Nvidia Unveils 'World's Fastest Notebook GPU'

Nvidia has what it calls "the world's fastest notebook GPU" with Tuesday's launch of the GeForce GTX 480M graphics processor based on the company's new Fermi architecture.

The Santa Clara, Calif.-based graphics chip maker said in a blog post that the new GPU "is DirectX 11 done right" thanks to a dedicated Tessellation engine built into GeForce GTX 480M chips that boosts the GPU's performance to five times that of other mobile graphics chips on the market, according to Nvidia.

The Fermi architecture and Nvidia's transition to 40-nanometer process technology mean more CUDA-enabled cores than previous-generation mobile GPUs from the company -- the GeForce GTX 480M has a whopping 352 cores in all and delivers 897 CUDA gigaflops of performance, according to Nvidia.

The new GPU has a 425MHz graphics clock, 850MHz processor clock and the memory clock spins at 1.2GHz with GDDR5 memory bandwidth of 76.8GB per second.
