Says its faster than Tegra 3

Huawei appears to be quite confident in its new quad-core K3V2 chip based on four ARM Cortex A9 cores and can be clocked at either 1.2 or 1.5GHz. The story gets a bit better as Huawei went on and compared its K3V2 against 4-PLUS-1 Tegra 3 chip in Transformer Prime as well as TI OMAP 4460 1.2GHz dual-core part inside Samsung Galaxy Nexus and came out on top.

In addition to the four ARM Cortex A9 cores, the new Huawei K3V2 chip also comes with 16 GPUs. Unfortunately, Huawei wasn't specific regarding the GPU inside the K3V2 but it did claim that K3V2 is currently the fastest quad-core on the market with lowest chip temperature in smallest package.

Apparently, the secret behind the K3V2 is actually its 64-bit memory controller as opposed to the 32-bit one on Tegra 3. According to Huawei's slides it ends up 49 percent faster in normal operation and in Quadrant Advanced, Antutu and Coremark benchmarks it pull ahead of Nvidia's Tegra 3. In GPU Basemark ES 2.0-Taiji and Nenamark, the K3V2 with its "16 GPUs" again moves ahead of Tegra 3.

Huawei didn't stop there as the actual lowest temperature is connected to low power consumption, another ace inside Huawei's pocket. The low power consumption is apparently achieved thanks to hardware, proprietary algorithms and faster signal detection that reduces power consumption.

Of course, we are talking about Huawei slides here but it still looks impressive. The K3V2 is apparently made at 40nm at TSMC which makes it quite similar to the Tegra 3, but of course 28nm Qualcomm and TI chips are pretty much just around the corner and we guess that Huawei's lead won't last for long.

We certainly look forward to see more about this chip as Huawei certantly shaked things up at MWC 2012.
