Not a massive difference for me 3788 in 2.0 and 3804 in 2.1. What jumps are others seeing?

This is with dual Sapphire 7950 Boasts (unmodded).

Gigabyte Radeon HD 7970 3GB - showing up as FirePro D700 in Luxmark 2.1

Tony -

This seems low - my un-modded 7950s are beating your 7970 (ignoring the fact I have two of them). I got a big speed boost when I did the NVRAM iMessage fix which seemed to enabled by cards power management (the fans spin up after, not before).

Otherwise, are you being hindered by being recognised as a D700 and the math it is doing is more accurate? I heard one of the big differences with FirePros was the driver traded speed for accuracy.

Ok retested the 7970 on the Haswell Z87MX-D3H + Core i7-4770K system:



I think this score is accurate now.

COOL

That looks better!

I wonder how much is CPU? What PCIe version are you plugged into on each rig? My cards are being forced back to v2 by the motherboard.
