My two main computers have the above listed processors, both running with stock coolers at stock speeds on Win7 64-bit. I'm really puzzled as to why my i5 system is benchmarking so much faster. I know it's a more modern processor and the individual cores are much more powerful, but the difference seems too large. I'm comparing them using Intel Burn Test on the standard setting with "All" threads enabled. Both systems use DDR3-1600 RAM and have turbo boost enabled and speedstep disabled. What we have is:
i7-920
X58 chipset (memory running in triple channel)
Time completed: ~25.3 seconds
GFlops: ~35
vs
i5-4670k
Z87 chipset (memory running in double channel)
Time completed: ~9.3 seconds
GFlops: ~96
Both processors top out around 80°C (thanks, stock Intel coolers), but both remain well above stock clock speeds (thanks to turbo boost), mostly maxed out, for the duration of the standard 10 replicates.
Both computers use SSD's, although obviously the one with the X58 chipset is limited to SATA 2.0 speeds.
Any help or advice would be appreciated. Just so nobody asks, yes, the latest storage controller, chipset, and various drivers are installed on both computer and both computers are virus/malware free. The i7 is my "main" computer and has a lot of software installed, so I confirmed the results in safe mode. They were identical.
