Check out the Dell
Axim X51v running
Windows Mobile 5.0, which replaced the X50v on Sept. 20, 2005!
The VGA Pocket PC marketplace is getting
interesting now that we have three brands to choose from in the
US, and more overseas. The Dell Axim X50v is the newest VGA model
on the block, sporting a 3.7" transflective display, dual
wireless and dual slots. Dell has never been known for their
sleek and sexy industrial designs, but that's changed with the
X50. The X50 models which replace the chunky Axim
X5 line have
curvy designs that look and feel good, and an attractive two-tone
color scheme. The HP iPAQ line has always been praised for their
attractive designs, but in Fall 2004, HP has gone rectangular
and business-like while competitors such as Dell and ASUS are
breaking out in style.
So far, VGA models are at the top of each manufacturer's
lineup, and each shares much in common having both CF and SD slots
supporting SDIO, a good amount of memory and at least one wireless
networking technology built-in. The Axim X50v fits in between the
ASUS A730 and HP
iPAQ hx4700 VGA Pocket PCs in terms of specs and
performance. It's also middle of the road in size, being just a
bit larger than the ASUS but smaller than the large, slate-like
For those of you who are new to Pocket PCs, VGA
models are new for Fall 2004 with the release of the Windows Mobile
2003 Second Edition OS from Microsoft, which adds support for VGA
displays and the ability to switch from portrait to landscape mode
on the fly. Previous Pocket PCs (with the exception of the discontinued
Toshiba e805) had QVGA 240 x 320
displays with fixed portrait modes. The 640 x 480 VGA display shows
you four times as much on screen in theory, though Microsoft's
implementation of VGA rarely goes that far. MS went for readability
which means you'll see approximately twice as much on screen when
using applications that support VGA rather than four times more.
We'll cover more of that in the display section of our review.
Features at a Glance
The Dell Axim X50v runs on a 624MHz processor,
has 64 megs of RAM, 128 megs of ROM, a CF type II slot, an SD slot
supporting SDIO, IR, Bluetooth and WiFi
802.11b wireless local area networking. It has a user replaceable 1100
mA battery and comes with a charger, cradle, slip case, manual and
Design and Ergonomics
Yes, this Dell has curves and good looks. Like
ASUS, Dell went with the curvy bottom designed that last year's best
selling iPAQ 1945 and 4155 sported. Everyone loved that look and it
lives on thanks to HP's competitors. Though not as small as those diminutive
iPAQs, the X50v is certainly not a very large Pocket
PC and is mid-sized. It feels great in the hand thanks to the
bottom and back curves and weighs in at 6.2 ounces.
The X50v has a plastic casing. The back is matte black
and curves to cover the sides of the PDA. The front has a silver surround
that wraps around the gloss black plastic upper and lower front faces.
It looks sleek, contemporary and was designed by HTC. Those of you
familiar with the Dell Axim X3 and X30 will immediately recognize the
5-way directional pad, though it takes a smaller form on the X50v. In
fact, the d-pad is as small as you can go without forgoing usability,
and it's a very sensitive control as are the application and side buttons.
Gamers may have to lighten their touch when playing on the Dell.
Above: comparing the size of the iPAQ
hx4700 and the X50v. The ASUS A730 (not pictured) is just a hair shorter
than the Dell.
The four front application buttons also look like shrunk
down versions of the X30's buttons. From left to right they launch Calendar,
Contacts, Outlook Inbox and Dell's Home launcher. As with all PDAs, you
can assign different applications to these buttons; and as with all Windows
Mobile 2003 SE Pocket PCs, you can press and hold a button to launch
a secondary application.
The power button is located top center, while the voice
recorder and wireless radio on/off button are located on the left side.
Above these two buttons on the left side you'll find the hold slider
switch which will prevent all buttons (even the power button) from turning
the unit on accidentally. Since the side buttons are easily accidentally
pressed, that's a good thing. The SD and CF slots are on the top edge,
as is the IR window and the standard 3.5mm stereo headphone jack. The
user replaceable battery lives under a door on the back and there's a
battery lock switch to keep the battery in place. The metal and plastic
stylus lives in a silo on the top right corner. The stylus end is small
so you'll want to have a good fingernail to get it out.
The mic is located on the top left corner and the speaker
is under the d-pad, so if you want to use this with VoIP apps, you'll
likely need to hold it upside down or get a stereo headset with mic.
The unit has a single LED on the top right corner which flashes blue
when one or more wireless radios are on. As with other Axim models,
the power button lights amber when the unit is charging and glows green
when fully charged. The power button flashes amber when a reminder
Horsepower and Expansion
The X50v is in the top tier of current Pocket PCs thanks
to its 624MHz "Bulverde" Intel XScale PXA270 processor. Currently,
only the high end Dell Axim X30 model (QVGA) and HP iPAQ hx4700 run the
same 624MHz processor. As you'd expect, the unit is fast, though you
may see the slightest delay opening menus and windows since the device
is running at VGA resolution. It is up to the task of even the most demanding
applications including action games and video playback.
The unit has 64 megs of RAM with 61.76 available to
the user. In addition, it has 128 megs of flash ROM, 91.43 of which are
available as "Built-in Storage". Dell
always uses Intel StrataFlash memory for flash ROM which is faster than
NAND. Though flash ROM is slower than the SDRAM used in main memory,
it's fast enough to run applications well.
For expansion, the Dell offers standard (not consumer)
IR, Bluetooth, a CF slot compatible with type I and type II cards and
an SD slot supporting SDIO and SDIO Now! All these expansion options
make for a very versatile and expandable device that will work with CF
cellular cards, GPS, presentation, modem and networking cards.
VGA Display and Sound
The X50v uses the Intel 2700G graphics processor with
16 megs of RAM. That's an impressive amount of video memory for a PDA,
and beats out all other models on the market. The 2700G comes in two
versions with 384k and 704k of on-die video memory, but the chip can
address additional external memory and that's how Dell got 16 megs into
this model. The graphics processor also offers 3D acceleration, while
all other PDAs except the gaming oriented Palm OS Tapwave
only 2D acceleration if any at all. The 2700G was designed by Intel to
work with the PXA270 family of processors, and it has a fast pipeline
between the CPU and graphics processor. In fact, I was surprised that
the 2D benchmark tests and video playback performance weren't higher.
I spoke with Intel about the 2700G's benchmark performance and they stated
that the graphics accelerator really shines for GDI and Open GL based
software rather than GAPI which is currently most commonly used by Pocket
PC applications, especially games. Since the benchmarks thus weight GAPI
tests more heavily than GDI tests, the X50v with its 2700G processor
doesn't get overall high scores in benchmarks. In our graphics benchmarks
below, the two tests where the Dell gets very high numbers are GDI tests,
while the other two tests where it scores low are GAPI tests. Dell released
update A02 in late January 2005 which offers some modest GAPI improvements
and we include benchmarks for both the original and updated ROM below.
Certainly, the potential seems high for this graphics
processor if and when we see apps that use GDI and Open GL rather than
GAPI for graphics. For those of you who aren't mega-graphics chip geeks,
GAPI stands for game API (application programming interface), GDI stands
for graphics device interface and Open GL is a common standard for
3D used on many desktop games. GAPI and GDI provide software developers
with two ways of sending data to a graphics device, with GAPI being
the commonly used standard put forth by Microsoft for Pocket PCs. GAPI
allows a program to write directly to graphics memory and is in some
ways the Pocket PC version of MS Direct Draw for PCs.
The X50v ships with two Open GL games that
show off the unit's 3D performance: Fathammer's Stuntcar Extreme driving
game and the 3D puzzle game Enigmo which look gorgeous and run well
on the Dell. If and when other games take advantage of the 2700G's 3D
acceleration, we could see some exiting games. Will we see games that
make use of this graphics processor? If other models use it the odds
are better, but if only the X50v bears the 2700G, we may not see many
titles because application developers need sufficient market share to
make their efforts worthwhile. In the meantime, game performance on the
X50v was certainly good enough for even demanding games.
The 3.7" LCD is sharp and reasonably bright. Text
is clear even at the smallest type settings. While not stunningly vivid
like the iPAQ hx4700, the screen is still very good and will please those
who want to view photos or videos. The 2700G
supports video mirroring, and the X50v has a Mirror Mode control panel
that allows you to enable mirroring when using a presentation card to
connect the Dell to an external display.
The Dell has a VGA 640 x 480
resolution display, while standard QVGA Pocket PCs have QVGA (quarter
VGA) 240 x 320 resolution displays. That means you'll see more on screen,
but not four times more, even though VGA is four times higher resolution
than QVGA. Why? Microsoft's implementation of VGA is designed to make
the display very attractive and readable rather than cram true VGA
into a small screen. That means those with good or poor eyes can use
a VGA Pocket PC, but if you were hoping to see four times more on your
screen, you'll be disappointed. Note that this is true of all VGA Pocket
PCs running Windows Mobile 2003 Second Edition, and is not Dell specific.
If you do have a hankering for true VGA and have excellent eyes, you
can download the free SE_VGA utility which allows you to run a VGA
Pocket PC in standard Microsoft VGA mode, true VGA or QVGA. However,
unless you have excellent eyes, you'll discover why Microsoft didn't
go with a true VGA experience: it's not
easy to see things or read text. Do check out Tweaks2K and the hack listed
site to get individual apps running in true VGA mode. That way
you can run the device in normal (and readable) standard MS VGA mode,
but have certain apps such as Adobe Acrobat Reader, NetFront
ebook readers running in true VGA mode.

The X50v, with fonts set to smallest
The Dell has great sound and its built-in speaker is
easy enough to hear in all but extremely noisy environments. MP3s and
movies sound great through stereo headphones plugged into the 3.5mm headphone
jack and volume is quite good. Like all Pocket PCs, the X50v has a microphone
and can record voice notes. Dell includes a Microphone control panel
that lets you use AGC (automatic gain control) or set mic gain manually.
The mic is located on the top left corner and the speaker is under the
d-pad. Like the iPAQ hx4700, the X50v's 3.5mm headphone jack works with
standard stereo headsets and headset mic combos that have 3.5mm 3 ring
plugs. That's good news for those of you who want to record better quality
voice notes or use the unit for voice over IP applications.
We use Spb
Benchmark to test PDAs. Since the Axim offers a variety
of CPU speed settings in the battery control panel applet,
we benchmarked it in both Auto mode, where the PDA sets processor
speed relative to current program demands, and Max mode which
sets it at a fixed 624MHz. On prior Axim models we've been
impressed with Auto mode's ability to step up processor speed
whenever improved performance was needed and found that Auto
and Max benchmarked similarly. The X50v is no exception, giving
nearly identical benchmarks for both modes. In fact, Auto mode
beat out Max mode narrowly in a few tests!
The X50v does well on benchmarks thanks to
its 624MHz processor. While the VGA iPAQ beats it in many tests,
the numbers are fairly close with the exception of graphics where
the iPAQ wins. We do wonder if the X50v could do better in the
graphics department with some driver tweaks since it has the
new Intel G2700G graphics processor and 16 megs of RAM. While
the 2700G is promoted as a 3D accelerator it does offer some
2D acceleration which should help it in 2D graphics benchmarks
and in general responsiveness when using non-3D applications
(games make use of 3D while most other apps would not).
How does the unit feel? It feels very fast,
though you will see some lag in screen re-draws when opening
menus and windows such as Programs and Settings. This minor graphics
lag is no stranger to VGA Pocket PCs but given the X50v's spiffy
graphics processor I didn't expect to see it. The lag is not
apparent inside of applications and is only noticeable when navigating
the OS, Using a utility like RegKing
2003 (free) to increase the Glyph Cache to 32,768 will increase
screen re-draw speed.
Video Playback and Gaming
Video playback is excellent on this unit. Watching
videos stretched to full screen is a lovely thing and will sell
you on VGA Pocket PCs. We tested the unit with PocketTV
Enterprise, PocketMVP and BetaPlayer,
three excellent 3rd party video applications as well as the built-in
Pocket version of the new Windows Media Player 10. Intel tells
us that the X50v has a codec for the 2700G graphics processor
to optimize video performance in WM10, and it shows because playback,
even in full screen is impressive.
PocketTV plays MPEG1
files and we threw our usual test files at it: "The Chosen" (a
neat BMW flick with Clive Owen) which is a 4:26 minute long,
10 meg MPEG1 file recorded at 320 x 240, 308 kb/s. PocketTV played
the file at 24.06 fps with smooth video and perfectly synced
audio. We tested the Spider Man trailer file commonly found on
the web (240 x 136, 452Kb/s encoded MPEG 1 file) at 24.11 fps.
PocketMVP, an open source free video player
got 23.95 fps with 12 dropped frames out of 6394 for "The
and 23.87 fps with 14 dropped frames out of 2640 for the Spider
Man trailer. That's very good performance.

BetaPlayer is an extremely fast open source free
video player that supports MPEG1, DivX and AVI files. There are
also plugins for ASF and WMV format, though we found that the X50v
and BetaPlayer couldn't play these formats using the plugin (it
does work on ATI-based machines like the iPAQ hx4700). BetaPlayer
has similarities to PocketMVP, another free open source player.
But PocketMVP doesn't support full screen playback and showed some
artifacts below the movie window on the X50v. BetaPlayer did an
awesome job. BetaPlayer played back "The Chosen" with

All in all, the X50v offers good video performance
and should please most folks. It is beat out in benchmarks and
screen quality by the iPAQ hx4700, but then the Dell is $150 cheaper.
The iPAQ has an ATI Imageon 3220 graphics chip, and these players
have ATI optimizations which may help the iPAQ get the best numbers,
along with HP's excellent video driver.
Most recent games ran fine on the Dell. Again,
if the games weren't designed for VGA mode, they will run in QVGA
mode stretched to fill the entire screen using pixel doubling.
Despite the stretching, games like most apps look quite good.
The popular emulator MorphGear
didn't give the best performance, clocking in an average of
5 to 9 fps playing GameBoy Advance titles like Tony Hawks Underground
2, Starsky and Hutch and Megaman Zero 3. It faired better with
NES games which are less demanding, and we got 28fps playing Galaga
and Super Mario Bros. 3. MorphGear had trouble drawing its own
on-screen program controls when the game was running, though the
game window and virtual controller rendered correctly worked fine.
WiFi and Bluetooth
The X50v has integrated WiFi 802.11b wireless
networking and Bluetooth 1.2. To turn on the wireless radios, simply
press the button on the left side of the PDA. As with the Dell
Axim X30, this button will turn on both wireless radios, which
seems a little odd, but you can turn them off using the on-screen
management utilities. WiFi has excellent range and was reliable
for us connecting to 802.11b access points using WEP encryption.
The X50v comes with Funk Odyssey VPN client and supports 64/128
bit WEP, WPA and CCX 1.0. Dell includes their excellent WLAN application
for managing WiFi connections, and this full-featured utility that
lists available networks in range (shows SSID, channel, signal
strength and mode), shows data transfer stats, lets you set the
default network and power saving mode and more.
For Bluetooth, Dell uses Broadcom's (formerly
Widcomm) excellent Bluetooth drivers and software, version 1.5.0.
The software helps you connect to Bluetooth enabled mobile phones,
ActiveSync, browse files on another Bluetooth enabled device, connect
to Bluetooth access points for LAN connections and even supports
Bluetooth headsets using headset and hands-free profiles. The Dell
supports the new Bluetooth 1.2 standard which is backward compatible
Though the Axim X50v is reasonably priced
for the hardware you get, Dell has included a nice software
bundle. You get Funk Odyssey VPN client, WLAN (a full-featured
WiFi manager), Resco Picture Viewer (an excellent photo viewer),
Data Backup which backs up your PDA to a storage card and the
cool VGA 3D games Enigmo by Aspyr and Fathammer's Stuntcar
Extreme (previously a Tapwave Zodiac exclusive). Both games
look fantastic on the Dell and really show off its VGA and
The X50v has a 1100 mAh Lithium Ion battery
that's user replaceable. That's an average capacity battery
for a Pocket PC, and a little low for a 3.7" display VGA
model running at 624MHz with dual wireless (large displays,
wireless networking and fast processors consume lots of power).
That said, battery life is average for a Pocket PC, giving
about 3 hours of actual use in average conditions consisting
of PIM use, working with MS Office documents, surfing the web
for an hour using WiFi, gaming for 45 minutes and playing a
few short videos. If you need more power, Dell sells an optional
2200 mAh battery which will increase the thickness of the PDA.
If you're a heavy wireless user, you may want to consider this
extended battery or a second standard battery. In our video
test, the X50v used 50% of its charge playing a 1 hour 20 minute
film using Windows Media Player 10. Brightness was set at 66%,
WM10 was set to stretch video to full screen and we had sound
piped out through stereo earbud headphones.
let's face it, we don't need 624MHz all the
time, but we may need longer runtimes when on the road. That's
why Dell allows you to set the CPU speed to Power-Saving (208MHz),
Normal (520MHz), Maximum Performance (624MHz) or Auto which
sets processor speed relative to demand. Auto can set the CPU
from 104MHz up to 624MHz depending on load and gives great
performance overall. I found the Power-Saving mode to be too
slow even for PIM lookups and working with Pocket Word documents,
but Normal mode is just fine and may get you 15 minutes
more out of your battery compared to Max mode.
Like prior Dells, you can charge the unit
in its cradle or use the included dongle adapter to plug the
charger directly into the PDA. This world charger is the same
model included with the X5, X3 and X30, but the connector and
thus dongle adapter are different. This means you can use chargers
from your old Dell with the X50v as long as you use the X50v's
adapter, but you will not be able to use cradles meant for
other Dell models.

Comparing the X50v, HP iPAQ 4700 and ASUS A730
If size really matters to you, the ASUS is the
smallest VGA Pocket PC, with the Dell being just a a hair taller
and the HP being the largest. The iPAQ is the only unit in this
trio to wear a magnesium alloy metal casing, while the other two
have plastic casings. While the HP is the largest, it needs more
space to accommodate its 4" display
which bests the 3.7" display
on the Dell and ASUS. Given that Microsoft's version of VGA doesn't
make things terribly tiny, the screen dimensions may not matter
to you unless you have tired eyes or want to view lots of photos
and watch videos frequently. The iPAQ does have the best quality
display: that Sony LCD is unbeatably vivid and no other Pocket
PC display rivals it.
When it comes to performance, the iPAQ wins,
though the Dell is close in many benchmarks. Though the Dell has
an amazing amount of video memory for a Pocket PC, the iPAQ still
beats it on graphics benchmarks. But honestly, all three look great
playing games and videos encoded at fairly high bitrates. As with
PCs, the megahertz wars mean that our machines are often faster
than most tasks we can throw at them. Battery performance is another
matter: today's fast PDAs with large color displays don't run as
long as we'd like. That makes the iPAQ and its very large standard
1800 mA battery a real winner.
If you want an integrated digicam, the ASUS certainly
wins since it's the only VGA model in the US with a camera.
Gamers will likely favor the Dell and ASUS over
the iPAQ since the hx4700's touchpad isn't the most responsive
or usable for action gaming.
On the pricing front, the ASUS A730 and Dell
X50v are $499 which the iPAQ is $649. We'll leave it up to you
to decide which combination of form factor, size, features and
performance match your budget and needs.
An excellent offering from Dell at a nice
price. The unit should suit power users and those who crave
the VGA experience. It offers excellent expandability, dual
wireless and enough memory to hold your favorite programs.
Not only that, it's attractive and feels good in the hand.
a very good device. Attractive
and ergonomic design, good price, VGA display, fast processor,
both CF and SD slots with SDIO support for the SD slot, Bluetooth
1.2 and WiFi, has Windows Media Player 10 which unlike Windows
Media Player 9 can play videos stretched to full screen (handy
if you want to watch your QVGA movies full screen).
Con: The buttons
are too easy to press and the d-pad is a little small. Standard
battery capacity is a lean: consider the extended battery.
The screen isn't as nice or as large as the iPAQ hx4700 nor
is current 2D graphics performance as good. But the Dell
costs less and we may see driver improvements in the future.
