The Lenovo LePad K2, based on Nvidia’s Tegra platform 3, was tested using GLBenchmark. The result was surprising. It looks like someone’s been running benchmarks on the next-generation Lenovo tablet. When you run the GL Benchmark using the free edition the results are submitted to a public community database for the world to see.
The graphics component of the Tegra 2 has 4 pixel shader units and 4 vertex shader units. In Tegra 3 the number of pixel shader units doubles while the vertex processors remain unchanged. This brings Tegra 3′s GPU core count up to 12. These benchmarks show Nvidia Tegra 3, code named Kal-El, graphics processor is much higher than the Tegra 2, but still maintain slightly lower performance than previous Apple products. The iPad 2 & iPhone 4S have Apple’s A5 processor which tout the graphics performance of the PowerVR SGX GPU 543MP2 and Tegra 3 doesn’t even come close.
However, when compared to the PowerVR SGX 543MP2 graphics core used in Apple’s A5 chip Nvidia’s solution is actually slower. The Lenovo LePad K2 running Tegra 3 is able to achieve 63.1 fps and Tegra 2 musters 24.1 fps which is actually a factor of 2.6, if you round up its close to 3X the performance. This is actually insignificant since Tegra 3 doesn’t stand up to the performance in the iPad2 which is 88.8 fsp compared it its 63.1.
Lenovo’s LePad K2 tablet offers an IdeaPad K1 tablet with a 10 inch screeen, Tegra 2 processor, and 1GB of RAM. It runs on Android 3.2 with a very interesting screen resolution of 1920 × 1152, probably not effective as it could correspond to the maximum resolution achieved by Tegra 3. This screen resolution isn’t taken advantage of in the GLBenchmark 2.1 since regardless of the resolution of the display test are always running at 1280 × 720 pixels so they won’t be slowed down by the vertical synchronization. This provides us with some very meaningful 720p results.
No details regarding pricing or availability were uncovered, but its presence in the GL Benchmark database seems to indicate that its release is pending. Looks like Tegra 3 still has a lot of work to do to catch up to Apple!
