AMD gave some information on their future Dual Core processors. These processors will be release mid-2005 for servers and working stations and during the last semester 2005 for desktops.
Currently, the 106 millions of transistors of the Opteron processors have a 130 nm fabrication process and use a 194 mm² surface. The future dual-core Opteron will have 205 millions of transistors (each core has 1 MB of cache L2) with a 90 nm fabrication process, and the die surface will be within 5% equivalent to the previous one. 95 Watt will be the maximum electrical consumption and these processors will have an improved pre-fetching and 10 of the 13 SSE3 instructions.
The SPEC benchs performances gains estimated by AMD should be from 39 to 57% between two mono cores CPU and two dual core CPU. These improvements might seem disappointing, but AMD specified that for heating reasons dual cores processors frequencies were 600 MHz lower than their mono core counter part. This situation explains the performances gap. With a 1GHz lower frequency, performances gains vary approximately from 26 to 45%.
