The T-Mobile G2 Preview
by Vivek Gowri on October 7, 2010 12:29 PM ESTOh yes, and now we get to the real stuff. Benchmarks! Let’s start with the CPU benchmarks to see how the 800 MHz 2nd gen Snapdragon matches up with the older 1 GHz parts. All of them implement the same Scorpion architecture, except that the MSM7230 is manufactured on a 45nm process as opposed to 65nm for the QSD8x50. Simple colour coding scheme going on in the graphs here: red for the G2, green for the 1st generation Snapdragon phones, blue for anything running TI OMAP 3 underhood, gold for the Hummingbird Galaxy S devices, black for the iPhone 4, and purple for the Marvell PXA930-running BlackBerry Torch.
The SunSpider Javascript benchmark is very quick on the G2. While the Froyo Nexus One remains the fastest on most of these benchmarks, the G2 is definitely getting there, probably due to the untouched Android build it’s running. So even with a slower clockspeed, the G2 has a better score on the JS benchmark than the NinjaBlur-equipped Droid 2 and the Sense UI-equipped EVO 4G.
Rightware’s BrowserMark puts the G2 right between the Droid 2, the Fascinate, and the iPhone 4, and about 20% slower than the Nexus One. Given the 20% reduction in clock speed, this is pretty understandable.
The G2’s Linpack score is about 25% lower than the Nexus One and EVO 4G, but significantly higher than the Droid 2’s score, potentially due to the higher throughput SIMD FP units in Qualcomm's CPU.
But the really interesting benchmarks are the graphics benchmarks. We’ll start with Neocore, which is Qualcomm’s benchmark to show off the capabilities of the Adreno GPU.
The score is quite good, at more than double the Nexus One’s. The benchmark is capped at roughly 60 fps which is why we see no real difference between the Adreno 205 and the PowerVR SGX 540. For a measurable performance difference we turn to our old favorite: Quake 3.
In a neutral gaming benchmark like the Quake III Arena demo, we can really get a feel for how fast Adreno 205 is. And though nothing on the market can touch the SGX 540, the Adreno 205 basically runs rings around the Adreno 200 in the EVO and Nexus One and even outpaces the SGX 530 in the Droid 2 and Droid X. So while the Adreno 205 isn’t world beating, it brings about a huge change by making the the 2nd generation Snapdragon SoC competitive as far as GPU performance goes. Qualcomm no longer comes with a GPU performance tradeoff.
The G2 comes with a pretty small battery, a removable 4.81 Wh (1300 mAh) Li-ion affair that can be easily accessed and replaced. The Nexus One came with a 5.18 Wh battery, the Droid 2 had 5.2 Wh capacity on tap, the Droid X had a 5.6 Wh unit, and the EVO used a 5.5 Wh battery. So naturally, with a lower capacity battery, the G2 comes with less battery runtime too. Thus far we’ve only had the time to run the 3G web browsing battery life test, and the G2 is way down at the very bottom of our charts, matching the Palm Pre Plus in battery life (which has a 1150 mAh battery). It’s not too bad, it’s on par with the Nexus One for minutes-per-Wh efficiency, but 3.5 hours of 3G web browsing is still not very good.
Update: We're adding battery life tests as we go, so here's the WiFi browsing test. Again, it's almost at the bottom, again it's about on par with the Nexus One on an efficiency level. It's a small battery, so when compared to phones that have 10-20% more battery capacity, it does look quite poor. What does seem to be consistent though is that the OMAP 3 phones are more power efficient, even on a per-Wh basis.
But given the 3G speeds the G2 is pulling, maybe we should give it a pass. T-Mobile's HSPA+ network is FAST, even in areas of Seattle that have rather poor signal coverage. On average, I'm pulling around 5.5 Mbps downstream and anywhere between 1 and 1.5 Mbps upstream. Interestingly, this is signifcantly faster than the speeds I saw out of Sprint's WiMAX 4G network on the EVO when I had it in June. While I can't vouch for areas that don't have T-Mobile's HSPA+ network enabled yet, the areas that do should see the G2 fly. It's T-Mobile's first HSPA+ device, so it should be able to utilise the full potential of the faster network.

Which port of Quake 3 is it that you used in the test?vol7ron - Thursday, October 7, 2010 - link
Could you also include the G1 "Physical Comparsion" statistisics for comparison?crazzeto - Thursday, October 7, 2010 - link
The last time I was dissapointed by an HTC device. The Verizon Wireless VX6800 wasn't very good, honestly it felt cheap from the get go. I did eventually have a partial fail of the slider hardware (half of it came off, for no apparent reason).More recent HTC devices seem better perhaps, but the VX6800 convinced me to go Motorola for my droid and honestly, I'm incredibly glad I did!

Why isn't the droid incredible running 2.2? The benchmarks make it look a lot worse when it should be on par with the evo and n1.fausto412 - Thursday, October 7, 2010 - link
i guess i can blame the iphone reviews for opening the gate,.is pc hardware that dead these days?
can we get an update on HTPC building and cable card compatibility? would like to learn more about that.
what about new monitor technology and how it compares to the old TN technology?
what about a high end gaming mouse review and round up that takes into accounts software support included and new features? g9x, cyborg, g500.
there is stuff to cover in pc realm. can get get back it?

The phone market is exploding while the PC market isn't seeing much growth. There also really haven't been much in the way of innovation on the PC side for quite a while now.Myrandex - Thursday, October 7, 2010 - link
The keyboard is surprisingly familiar to the Touch Pro 2's (superior to every other keybaord I've tried) keyboard, I do feel the need that with the space of such a large screen, another row of keys would have been nice to get a dedicated row of number keys across the top.The hinging mechanism is definitely interesting though!

Is this phone SIM free? I would love to use it on AT&T.Roland00 - Thursday, October 7, 2010 - link
if you do so the phone will just reload the OS from an included rom chip. Is this true?phoenix79 - Thursday, October 7, 2010 - link
Am I the only one that's noticing some pretty blatant errors in this article? First is the virtual keyboard, mine came with Swype installed alongside the stock one and enabled by default. As for the 2GB of memory, 5 minutes of googling and you would find out that the phones physically have a 4GB chip in them, this has been known for days.It seems that the fact-checking here has gotten considerably worse as of late...
