The HTC Sensation benchmarks are still scant, but there is at least one GL Benchmark measurement.

I reserve judgement until I see more benchmarks on final hardware.

It is way too early yet to draw judgement. The Adreno 220 is a powerful GPU, though coupled with the Snapdragon 8260, I have some doubts as to its performance. It should be interesting, though as we'll see what type of a performance gap we can expect with different SoCs.

Remember the benchmarks for the MSM8660 w/ Adreno 220? They were rather impressive:

Also remember how poorly the early Galaxy S 2 performed:

Updates to the drivers/hardware have had a transformational effect on the benchmark results (GPU bench). Similar can be the case with the Sensation.

Lets see when more results start to filter in.
