Performance
I’ve been skirting around it for no real reason, but the obvious other big important feature on the Sensation is that it’s the first dual core 45nm snapdragon SoC we’ve looked at in a shipping device. The HTC Sensation is built around a 1.2 GHz Qualcomm MSM8260 SoC with Adreno 220 graphics and integrated Previously, we looked at 3D performance on a 1.5 GHz Qualcomm MSM8660 in a Mobile Development Platform, and briefly in our initial hands on preview piece at Uplinq. There, we saw that performance was about where it should be given the difference in resolution between what we had tested (WVGA - 800x480) and the Sensation’s qHD (960x540) display.
The elephant in the room is what CPU performance on MSM8x60 is like. Dual core snapdragon consists of two scorpion cores clocked at up to 1.5 GHz. Anand is going to give a much deeper CPU architecture dive when he looks at the MSM8660 inside the EVO 3D (again, the x in MSM8x60 merely denotes which modem is onboard), but for now I’m going to present all the benchmark results for the Sensation.
First up are our web benchmarks, which primarily test JavaScript and page rendering. We’re still running SunSpider 0.9, though we’ll soon switch to 0.9.1 and report that alongside. JavaScript performance on HTC’s browser isn’t as good as it should be, and I’m a bit disappointed here that things aren’t better. We’ve seen HTC’s browser result in lower scores before, but it still is at odds with what Qualcomm has told me about how closely the two collaborate to optimize V8 for scorpion.
Flash is next, and here the Sensation delivers pretty good performance. It’s hard to make a direct comparison against the Optimus 2X again because we’re dealing with WVGA versus qHD, and we run this test aspect scaled.
I’m putting Neocore up next because I want to mention again that we’re capped at vsync. We had some hope for a while that we could turn vsync off on handsets, however this is only possible on development hardware, not final ROMs that ship in devices. Odds are you won’t see this pop up again in our suite unless we can make it actually say something. We’re at the Surround’s 60fps wall even at qHD.
GLBenchmark 2.0 is a mainstay in our benchmarking section, and I’ve already broken down results in our HTC Sensation hands on back at Uplinq. Things have actually improved a bit since that hurried benchmark run over dinner in San Diego, with the Sensation posting around 2fps higher in Egypt and Pro. Again keep in mind the resolution differences between everything here, there’s a 1.35x increase in pixels going from WVGA to qHD.
Next is BaseMark ES2.0, which is a nominally updated version of the hugely popular, industry-standard 3DMarkMobile ES2.0. Here we run at the default resolution, which is VGA, and thus get a picture without being constrained to just native resolution constantly. This one is a bit new for us, and I expect that Anand and I are going to explain things a bit more in the EVO 3D story. For now, just take away that MSM8x60 appears very speedy.
The Android port of Quake 3 is what we sort of started all of this mobile 3D benchmarking with, and we’re still running it even if it’s starting to hit vsync. The results look strange here until you realize that this is again running at native qHD resolution on the Sensation.
Next up is Linpack, which added a multi-threaded benchmark mode earlier this week. I’ve run it on all the dual core devices I could get my hands on. The initial multi-threaded version had some issues which were fixed on Tuesday, giving more accurate results. We’ll still run the single-threaded version alongside. The 20% jump in clocks shows itself nicely on the Sensation in single-threaded linpack compared to all those 1 GHz MSM8x55 phones we’ve tested.
Last and most definitely least is Quadrant, which I think we've gone over our numerous reasons for disliking a few times. The tests themselves are starting to look seriously dated, including 3D tests which render improperly on Android 2.3 and are themselves up against the 60fps vsync cap through their respective runs. I'm sure that the rest of the poorly documented subtests are equally as subpar, however it's become something of a de-facto standard in certain circles.
As an aside, I don't think we'll see Quadrant around for much longer, as there are better, more robust, fully documented tools by some established big names coming to the Android market (for free) shortly. All of those will probably quickly and thankfully replace Quadrant, as they all are gunning for its "go-to standard" status as the tool everyone runs, at least from the Android market. I have no doubt they'll quickly succeed.
The state of benchmarking on Android right now is a bit unbalanced, and what everyone wants is a system trace or general use benchmark that will show more than how the CPU does in synthetics and the GPU in synthetics. I fully expect all of that to change this calendar year. Just be patient.

Some reviews mention that, by cupping the non-metal parts at the back of the phone with your hands (like whule using it in landscape mode) seriously attenuate reception of one of the radios. Have you tested for this issue?warisz00r - Friday, July 1, 2011 - link
I've read the Connectivity part again now and found the mention about it, but you still didn't mention how this problem impacted your day-to-day experience with the phone.Brian Klug - Friday, July 1, 2011 - link
For me honestly the Sensation is still in-line with other handsets I've tried. You always end up dropping ~15 dB, sometimes more and sometimes less depending on whether the device has diversity with a second antenna up at the top.It makes a difference when you're on the lower end of signal, but again not more than any other smartphone (excluding the iPhone 4).

What?? no side-by-side pictures with the iphone 3g/s?bobbozzo - Friday, July 1, 2011 - link
HML/MHL on page 4clos instead of close on a previous page

Thanks, those are fixed now!-Brian

Is that an app, or built-in? I don't have it on my Evo 4g running 2.3thanks

NM, saw the icon on one of the app list pics; It's GPS Test Plus.Brian Klug - Friday, July 1, 2011 - link
GPS Test Plus - it's awesome, and it's just using the raw NMEA GPS output which includes SNR to make a nice visualization. ;)-Brian

brian,can it play 1080p flash videos in the browser flawlessly?
