AMD Claims Forthcoming “Shanghai” Chip to Be 35% Faster than Existing

From X-bit Labs: A vice president of Advanced Micro Devices said in an interview that the forthcoming quad-core AMD Opteron processor code-named Shanghai will have roughly 35% performance advantage over predecessor at the same clock-speed. If the information is correct, then AMD’s chips will have all chances to challenges products by arch-rival Intel in the higher-end segment.

Pat Patla, general manager of AMD’s server and workstation chip business, said in an interview with IDG News Service that AMD Opteron “Shanghai” would “give a 35% performance boost over Barcelona on average” and would also trim power consumption by 35%, which automatically transforms into colossal performance per watt improvements over existing quad-core AMD Opteron processors.

The advances are direct results of larger 6MB level-three cache, thinner 45nm process technology as well as micro-architectural improvements that boost instructions per clock (IPC) throughput.

Mr. Patla indicated that the first 45nm quad-core AMD Opteron chips that are scheduled to arrive in Q4 2008 will fit into mainstream 75W thermal envelope, whereas other models – which are due in Q1 2009 – will offer 55W thermal design power to fit into blade servers as well as 105W thermal envelop for high-performance machines.
