EE Times reports Huawei has revealed high-end smartphones and tablets based on a quad-core chip designed by the company's HiSilicon division. Huawei officials claim the 1.2-1.5GHz KV32 chip outperforms NVIDIA's Tegra 3 SoC by 30 to 50 percent across a range of benchmarks.
A 64-bit memory bus--twice the width of the tegra3--is one of the main factors in the performance of the KV32, said Jerry Su, chief architect of the chip. Built in a TSMC 40 nm low power process, the chip fits in a 12x12mm package
The KV32 uses four ARM Cortex A9 cores and a 16 core graphics chip co-developed with an unnamed U.S. chip designer. The two collaborated on the GPU’s architecture and the U.S. partner handled its implementation.
The graphics handles 2-D and 3-D work and helps a handset deliver 35 frames/second video compared to 13 fps for Tegra 3 and 8.4 for a dual-core Qualcomm Snapdragon.
