G1 Assassin2 SandyBridge-E vs IvyBridge-E Some Bench Marks

[Gbmaryland]

So,

I decided I wanted a motherboard GPU combo that supported PCIE 3.0 without having to force it, or potentially deal with some instability.

For giggles I replaced the Sand Bridge-E with an IVY Bridge-E CPU after installing the G1Assassin2 Modded 12w BIOS.

I ran some simple bench marks before and after the swap; PCMark 7, 3D Mark 11, and Bioshock Infinite's Benchmark Tool.

What's interesting is that while the Ivy Bridge renders graphics faster as a system as a whole, it's not truly fast than the Sandy Bridge CPU.

Ivy Bridge-E (i7-4930k):

Bioshock Infinite Test - note the CPU in question for a dataset in listed at the BOTTOM of that set:

So, with BioShock, specifically, we see that because of the PCIE 3.0 being available, the minimum frame rate goes up for the native resolution I'm using [2560 x 1600 ]

Interestingly, while the overall stats are lower on the i7-4930K, the frame rates make a HUGE visable difference in the benchmark; you can actually see the system whipping through the screens, as opposed to pause and jerk a fair amount on the i7-3930K.

Neither of the CPUs or anything in the system is overclocked.... and the RAM is running a 1600.

Does GPU-z show that your video card is running with pci-e 3.0 mode?
I think that Nvidia only has two video card models that support pci-e 3.0 with X79 motherboards.

Yep, that the was the difference... I ran GPU-Z after noting that many of the individual tests were slower. Thet became clear I should check PCIE bus speed, as it didn't make sense otherwise.

if I did not have a C1 stepping of the SB-E, I would have just turned on PCIE using the NVidia tool. (It appears the the early revision of SB-E had a compatibly issue, but later ones will work without stability issues.)

Can you tell what the intel network driver is for?, how is it used, sorry I know its not part of benchmarking, would really like to know, as im debating whether top get the cpu, or get the new g1assasin3 first.
