Scores for the unreleased HTC Shooter/EVO 3D creep up on benchmark websites, nothing spectacular

Smartbench is a relatively new test, which accounts for multiple cores, and the performance results there are as follows:

GLBenchmark 2.0 measures the GPU productivity, and the Adreno 220 graphics subsystem in the HTC Shooter comes on par with Tegra 2, giving it up only to the OMAP4 chipset on the LG Optimus 3D:
Of course, these are just pre-production tests that software engineers and testers sometimes do when they are tweaking prototypes, and they stay in the benchmarks' databases. We wouldn't trust these results with that huge difference, not on a prototype, and will wait for the final unit before we pass any judgment.
On a different note, Qualcomm's custom-made Scorpion core, which is loosely based on ARM's Cortex-A8 architecture, has been around since the first 1GHz Snapdragon, and the other dual-core phones are based on Cortex-A9, which is optimized for multiple core performance, so there might be some merit to the general productivity results, despite the 20% higher clock speed. The lag in the GPU tests is more puzzling, though, and again makes us pause and wait for a final unit before we do any ranking.

We will be at Sprint's event at CTIA 2011 live, and will make sure to give you some hands-on time with the device, and solve the performance puzzle.
