As we'd expect, the new machine's Ivy Bridge-based CPU is barely faster than the Sandy Bridge-E-based Core i7-3930K at stock settings. But it overclocks better. The difference is quite apparent in SiSoftware's Sandra Arithmetic and Cryptography metrics (the latter of which uses host processing power for the SHA-based hashing test).
The new system has faster RAM, but Sandra’s bandwidth scores still appear exceptionally high. Perhaps the newer CPU’s memory controller is just that much better? The bandwidth result affects our measure of encryption/decryption in the Cryptography test, too.
