First 64-bit multi-core AMD processors
This Thursday, at the second anniversary celebration of Opteron, Advanced Micro Devices (AMD) started selling world's first 64-bit multi-core processors. At first they are only available for servers and workstations as dual-core AMD Opteron CPUs. AMD also announced the new brand name for desktop dual-core processors: AMD Athlon 64 X2. We will be able to buy these in June.
Besides improved performance and true multi-tasking another great thing about dual-core AMD processors is that you will not have to replace your motherboard (if it has socket 939 or 940). You only need to upgrade the BIOS and replace single-core CPU with dual-core one and you are ready to rock.
