Oh 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. 

SunSpider Javascript Benchmark 0.9

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 BrowserMark

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.

Linpack

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.

Android Neocore Benchmark

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.

Quake III Arena demo four - Native Resolution

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.

3G Web Browsing Battery Life

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.

WiFi Web Browsing Battery Life

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.

    Sorry, I wasn't criticizing the article. I really like that AT phone reviewers use the said phone for a few weeks before posting their full write-up. It shows exceptional polish and class on their part.

    Like you mentioned, this "preview" has about the same amount/quality of information that a typical "review" provides.

    Umm, sometimes the stuff in plain sight is the hardest to spot :) Sorry from me. Reply

    6Mbps down and 1Mbps up is what I get indoor with my HTC Hero (which is only 7.2 Mbps HSDPA) here in Canada. That doesn't sounds like HSPA+ speeds at all. Reply

    Yeah, And I get barely .5 Mbps from my Huawei 3G router with external antenna. That is explicitly on HSPA+.

    At the same time I get extremely good .2 Mbps from EDGE on the same spot cause the 2G tower is a bit closer...

    Basically, unless testing at the same time, during night, during clear weather, in the same setting, at the most optimal position, any such comparison is moot.
    There are just too many unaccounted variables.

    Still, 6 Mbps is below 7.2 so it is not a proof that HSPA+ is even being used. Reply

    Using my Sprint HTC Touch Diamond and booting into Android 2.2, the Speedtest.net app reads after 5 tests:

    136-710 kbps down
    83-160 kbps up
    140-190 ms ping

    Using WM6.5 and mobile speed test web page, I can get 1,300 kbps down, 800 kbps up, and 130 ping. WM6.5 is a bit easier for my meak hardware to run than Froyo.

    That's inside with a signal moving between 0 and 1 bar. It may seem pathetic, but it's fast enough to stream Youtube.

    .5/.2 Mbps seems "offly" low. Are you sure it's not MBps? Reply
  • sprockkets - Thursday, October 07, 2010 - link

    Not on EDGE :) Reply

    .5 is on the last straws of 3G signal & not very bad weather
    .2 is on 1800MHz 2G network with reasonable signal quality

    Why I mentioned is that there encoding and band used is only one of the variables. And in most cases not the most important one.

    It does come preloaded with SWYPE. I personally use it when I only have one hand free and can't flip the keyboard out.

    I think it is at least worth mentioning.
