Way back at CES we saw our first glimpse of MSM8x60 and Qualcomm's Snapdragon Mobile Development Platform (MDP) with an MSM8660 SoC inside. Though we couldn't run any benchmarks on it, we got a sneak preview of dual core snapdragon. This year at MWC Qualcomm gave us a considerable amount of hands-on time with the same MDP hardware. We did a bit of testing, and then Qualcomm did something awesome - they let us take an MDP with the MSM8660 inside home with us.

In case you haven't been following, MSM8x60 is Qualcomm's first dual-core SoC. It's two Scorpion cores, an Adreno 220 GPU, and cellular modem all built on the 45 nm process. Like the rest of Qualcomm's lineup, the x in MSM8x60 can either be a 2, denoting GSM, UMTS, and HSPA+ support, or a 6, denoting all the same thing but with CDMA2000 and EVDO. Similarly, 9 will connote LTE support when we get to that point as well. MSM8x60 comes clocked at either 1.2 GHz or a higher 1.5 GHz. The MDP we were given was the higher 1.5 GHz variant. The MSM8x60 is the successor to MSM8x55, which is single core 1 GHz Snapdragon and Adreno 205, also built on 45 nm process. 

Qualcomm Mobile Development Platform (MDP)
SoC 1.5 GHz 45nm MSM8660
CPU Dual Core Snapdragon
GPU Adreno 220
RAM (?) LPDDR2
NAND 8 GB integrated, microSD slot
Cameras 13 MP Rear Facing with Autofocus and LED Flash, Front Facing (? MP)
Display 3.8" WVGA LCD-TFT with Capacitive Touch
Battery 3.3 Whr removable
OS Android 2.3.2 (Gingerbread)

It's been a bit busy since we got the MDP home with us, but we've run and re-run tests on the MDP all along and are ready to talk about GPU performance. The MDP we have right now is optimized for evaluating graphics performance, which we'll take a look at in this article. We'll then go into architectural changes between Adreno 200, 205, and 220, and then do the same combo of performance numbers plus architectural deep-dive with the CPU side of things in a future article. 

The MDP itself is stark black and completely utilitiarian - it's a glossy, tall, extremely square package, but a smartphone nonetheless. It runs Android 2.3.2 (as an aside, isn't it ironic that prototype devices are running newer builds of Android than most smartphones you can buy retail right now) and has a number of interesting extras. There's a 13 MP rear facing camera with LED flash, front facing camera, 3.8" WVGA display, speakers, microHDMI port, microUSB, and microSD card slot. The MDP's battery is a comparatively tiny 3.3 Whr, but the entire package is totally mobile. 

The one we have is again optimized for GPU testing, and sadly lacked cellular connectivity or WiFi, but gets the job done nonetheless. 

The MDP's purpose is to act as a pre-commercial handset for software development rather than be something you'd ever carry around. Making reference hardware designed for developers isn't anything new in the SoC space - look no further than OMAP's Blaze platform. Qualcomm started making MDPs with the MSM8655 and sells them through bsquare, who sells them for $995. Though it isn't up yet, both these pages will soon have the MSM8660-based Mobile Development Platform. 

One of the more interesting things about the MDP is that because it's a development platform, not a consumer device sold by an OEM though a carrier, it can either have Vsync enabled or disabled. This is the framerate cap we've seen on virtually every other device, which usually is right around 60 Hz. Through adb, we can turn Vsync on or off on the fly, then reboot Android's surface flinger and run tests. Sadly this procedure, while simple on the MDP, doesn't work on any other devices that aren't running Qualcomm's Android builds.

Since all of the devices we've tested thus far have been commercial, they've shipped with Vsync on and thus are limited to around 60 FPS. Thus, more than a few platforms could have had instantaneous bursts during test runs which are clipped to Vsync. To be fair to those, we've run everything on the MDP with Vsync on and off for illustrative purposes. 

The MDP we tested was running all out, with maximum clocks and no power management thorottling CPU or GPU clocks down based on usage and load. As a result, testing was performed constantly plugged into a beefy USB AC power adapter. Though these benchmarks show off what MSM8660 is capable of, actual performance in shipping devices will obviously be different depending on UI, power management, and display resolution choices made by Qualcomm's OEM customers, like HTC.

    Um, the benchmarks for OpenGL ES2 and Egypt run on the iPhone and iPad. Reply

    I was referring to 3dmark, that was his question. Reply

    Except, the MSM8960 is what we should be looking for, due to the integrated LTE antenna. Right?

    Does the 8960 have the Adreno 220? I forget. I think 28nm 8960 will be substantially faster and more power efficient than Tegra 2, assuming T2 doesn't improve that much architecturally by the time 8960 is in mass produced devices.

    The MSM8960 will perform identically, except it will have LTE. All MSM8x60s will have the same hardware, with the sole difference being the cellular antenna. Since this MDP has no cellular connectivity at all (or even WiFi) it's a moot point, anyway. They can't test any of that kind of stuff yet. Reply

    Great point. Thanks for the clarification.

    Really impressive SoCs coming out. I just wish battery tech evolved instep with SoCs.

    8960 will bring a new CPU design; Krait will replace Scorpion. Reply

    Tegra 2? The 1.5 Ghz quad core Tegra 3 will be long out before the 1.5 Ghz dual core Snapdragon chip is out. I think they said it will ship around late Q4 this year Reply

    Lucian,

    You have many postings all over the web where you're singing the praises of Tegra's graphics performance even when faced with irrefutable benchmark data, such as that from Anandtech, proving that Tegra 2 often has inferior graphics to SGX based devices like iPad2, and now ,it is clear that Tegra 2 has inferior performance to Qualcomm's 8660. Is Tegra 3 really better than future products/chipsets from Apple, TI, Samsung and Qualcomm, and do you think that these other companies are just going to stand still while NVIDIA alone produces new chipsets? Hmmm...think it through man, everybody has a killer next chip.

    Also, you've posted above a strong statement about the availability of future Tegra 3 quad core based OEM products vs. the commerical availability of those based on dual core products Qualcomm, TI and others. - again, how do you know? Just because NVIDIA says something in the press doesn't exactly make it so. Please stop being such an obvious NVIDIA fanboy, and do a little more research before you post such drivel.

    On the 8655MDP VEE is available in the Trepn Profiler app under the Current option.

    Thanks.

    Considering the A5 is a good gauge for whats going to be in the next iphone, I think it would be interesting to see the ipad2 benchmarks in the comparison. Reply
