SAN FRANCISCO – China gave a look at a national microprocessor design that aims to power a petaflops supercomputer in a paper at the International Solid State Circuits Conference here. At the same session, IBM described a 5.2 GHz mainframe processor, continuing the push the limits in CPU frequency.
Separately, Advanced Micro Devices gave more details of its new Bulldozer core and Intel described two server chips.
Weiwu Hu, lead designer of China's Godson processor family, described the Godson-3B which will emerge in a high-performance system from Dawning (Shenzhen) this summer. The Dawning system will use 3,000 Godson-3B chips to deliver about 300 Teraflops, Hu said. A future system aims to crack the petaflops barrier using the chip.
The eight-core 65nm processor delivers 128 GFlops at 1.05 GHz and is already in production at STMicroelectronics. The next-generation Godson-3C will be a 16-core version targeting 512 GFlops at 2 GHz operation in 28nm technology and is still two years away, said Hu.
The Godson-3B is based on a 64-bit MIPS core with 200 instructions added for x86 compatibility and integrates vector processing units. The chip was previously described at Hot Chips in August.
The chip and a related operating system make up one of 16 projects funded by China's national science and technology initiative. As such it will receive an estimated $5-10 billion over the 2006-2020 period, Hu said. Other projects include next-generation VLSI process technology, 4G networking, high res satellite system and China's space exploration program, he said.
