AMDs’ upcoming 12-core chips will draw the same power as existing six-core chips, but’ll have reduced clock speeds, a company official said. The company’s upcoming 12-core server chips, code-named Magny-Cours, put two six-core chips in one package. The same silicon is used in existing six-core chips, code-named Istanbul, which are part of the Opteron line of server processors. AMD designed Magny-Cours chips to draw the same power as Istanbul chips, said Pat Conway, a member of AMD’s technical staff, in a presentation at the Hot Chips conference at Stanford University. AMD is reducing the clock speeds of the Magny-Cours and added that power management features are being added.
