NVIDIA said that they'll be releasing their own line-up of ARM based CPU cores, designed for home PCs, servers and even "supercomputers."
The new set of ARM based CPUs will be fully integrated on the same chip as the NVIDIA GPU, meaning it'll consume less power and increase graphics performance. NVIDIA's line of CPUs are based on ARM's current Cortex A15 processor for its future generation Tegra mobile processors.
Bringing both the CPU and GPU together on the same chip means that the ARM CPU will consume less energy and output up to 20x better performance in graphics in some scenarios. NVIDIA might be a very interesting contender in the mobile CPU market with their ARM based chipsets, offering more consumer choices over Intel or AMD.
Microsoft also announced Windows 8 will be available on the ARM processor.
