Server Maker Leaks Clock-Speeds of AMD Opteron Bulldozer Chips

From X-bit Labs: Gateway, a maker of servers, has accidentally revealed clock-speeds of Advanced Micro Devices' upcoming AMD Opteron chips for servers code-named Interlagos and Valencia, which are based on Bulldozer micro-architecture. As projected initially, clock-speeds of the new microprocessors are not high.

Based on the configurations of Gateway's future servers (which were noticed by Bright Side of News web-site), AMD's initial lineup of Opteron 6200-series microprocessors will consist of four models: two with sixteen cores, one with twelve cores and one with eight cores. The chips with twelve and sixteen cores are multi-chip modules with two 6- or 8-core dies, whereas the one with eight cores is likely to be powered by a single eight-core die code-named Valencia.

Clock-speeds of the chips are not really high because AMD needed to limit thermal design power to maintain compatibility with current-generation G34 socket servers. The four models that AMD seems to plan to release initially will be the following SKUs:

Opteron 6220: 8-core, 3.0GHz, 3.5GHz Turbo, 4MB L2, 8MB L3 cache
Opteron 6234: 12-core, 2.4GHz, 2.9GHz Turbo, 6MB L2, 12MB L3 cache
Opteron 6272: 16-core, 2.1GHz, 2.6GHz Turbo, 8MB L2, 16MB L3 cache
Opteron 6276: 16-core, 2.3GHz, 2.8GHz Turbo, 8MB L2, 16MB L3 cache

At present AMD's fastest twelve-core Opteron 6180 SE server chip works at 2.50GHz, so it remains to be seen how significantly faster will the new sixteen-core Opteron 6276 chip with 2.30GHz/2.80GHz clock-speeds be against its predecessor.
