Lenovo LePad K2 Nvidia Tegra 3 Tablet Benchmarked, Lags Behind the iPad 2

The GL Benchmark test suite seems to become a major source of leaks for the performance of upcoming tablet models as recently a new set of results, this time for Lenovo's LePad K2 Nvidia Tegra 3 based slate, made their appearance in the benchmark's database.

Every time someone runs the free edition of GL Benchmark, the results of the device are automatically uploaded to a public community database, which can be accessed from the apps official website.

The latest results to arrive in this manner seem to have originated from Lenovo's upcoming LePad K2 tablet that is designed around the Nvidia Tegra 3, code named Kal-El, system-on-a-chip (SoC) device.

With its quad-core ARM-based processor and improved graphics core, Kal-El should have no problem taking the first spot in this top, but it seem like things aren't as simple as this since the LePad K2 is considerably lagging behind the iPad 2 in graphics performance.

The results seem to be rather disappointing for Nvidia which was particularly confident in the graphics performance of its mobile chips.

This isn't to say that the Tegra 3 GPU is delivering bad performance, as after all, Heise.de explains, it actually manages to be 2.6 times faster than the previous Tegra 2 SoC.

However, when compared to the PowerVR SGX 543MP2 graphics core used in Apple's A5 chip Nvidia's solution is actually slower.

Lenovo's LePad K2 tablet was leaked at the beginning of this week and apart from the 1.6GHz quad-core Nvidia Kal-El SoC it also includes 10.1-inch screen, 2GB of speedy 1,600MHz DDR3 RAM, a standard-sized USB port, and a rear facing camera.

The tablet's most distinguishable feature is the back-mounted fingerprint scanner that apparently doubles as an optical joystick.

No details regarding pricing or availability were uncovered, but its presence in the GL Benchmark database seems to indicate that its release is pending.

This is an interesting development, but is the comparison o the Tegra 3 to the A5 adjusted for resolution difference, since the Lepad K2 runs at 1920 x 1152 and the iPad 2 runs at 1024 x 768. I'm not familiar much with how OpenGL tests, but if it's a simple frame rate, then a true comparison should be more sophisticated then this one.

The benchmark was actually run in the offscreen mode at 720p resolution for all the devices, so the results can be compared with each other.

1. Screen resolutions of IPad2 and K2 are _very_different_, with K2 having 3.5 times more pixels.
2. The leaked benchmark is done on a prototype of K2, will see how good they will optimize the drivers before sales...
