Small displays produce big results in GPU benchmarks

Update: As reader Chris wisely points out, the Slide is running a lower resolution (HVGA vs WVGA) so the benchmarks should be pushing less pixels. This explains why the slower phone is able to produce more frames per second.

Welcome to another episode in blog journalism where we provide the questions and you provide the  answers. We came across some interesting news tonight and I have no way of explaining it so I come to our loyal readers with the evidence and maybe you can help me solve this case.

Earlier tonight, I was filming some GPU benchmarks with all our high-end Android phones and I planned on making an extensive post tomorrow. I tweeted a link to the video so others could have a sneak peek before the post went up.

Almost immediately, I received a tip that the someone with the myTouch 3G Slide was reporting higher scores in every GPU benchmark. I don’t have a Slide on hand, so I had the guy perform 4-5 tests and he sent me over all the results. Surprisingly, the Slide outpaced much faster phones like the Droid, EVO, Incredible, and a Nexus One that had Android 2.2 installed.

So what kind of GPU is included with that Slide? This is where the picture gets a little fuzzy. The Slide features the 600 MHz Qualcomm MSM7227 (ARM11 based) which is geared towards mass-market smartphones and not the high-end. Qualcomm’s official press release gives little details on the GPU and only mentions it has “hardware-accelerated 3D graphics”.

Using a system information tool, we were able to determine that the Slide is using an Adreno GPU, which some of you know is also included in the much faster 1 GHz Snapdragon.

I know from my earlier testing that the Droid has the fastest GPU (200 110 MHz PowerVR SGX 530) and it outperformed the Nexus One’s Adreno GPU (even though the Nexus had the advantage of Android 2.2).

If the Slide and all other Snapdragon phones use a similar Adreno GPU, then how is it possible for the Slide to outperform all others when the CPU runs at 600 MHz and the firmware is still Android 2.1? Believe it or not, the Slide is scoring nearly 2x in some taxing benchmarks like GLBenchmark and NeneMark1.

Surely, there is some reasonable explanation for this. From what I know, the Slide GPU should be last when compared to the other high-end phones, but it actually comes up first. Expect a full report later today when we dig a little deeper.

Benchmark results from myTouch 3G Slide

I’m only listing the results for the myTouch 3G Slide and posting the screen caps as evidence. For full benchmark scores on all devices, look for our detailed post tomorrow.

Know of any other GPU benchmarks for Android? Share the links and we will be glad to test them out and post our results.
