What key search rate can I expect from hardware X?
Detailed list forthcoming. Some ballpark estimates are listed below.
Dual-core desktop CPUs, 32-bit mode: 100-250 Kkey/s. Dual-core desktop CPUs, 64-bit mode: 150-450 Kkey/s. Quad-core desktop CPUs, 32-bit mode: 200-400 Kkey/s. Quad-core desktop CPUs, 64-bit mode: 300-750 Kkey/s. NVIDIA GT200 GPUs: up to 6.5 Mkey/s AMD Radeon 58XX, 68XX GPUs: up to 23.5 Mkey/s. AMD Radeon 69XX GPUs: up to 19.5 Mkey/s.
