7970 and battlefield 3

[sadfacebunny]

Okay i read last night in this article


http://www.tomshardware.com/reviews/fx-4100-core-i3-2100-gaming-benchmark,3136-9.html

that the 7970 bottlenecks battlefield 3.

could someone elaborate if that's true>? also is battlefield 3 just that hardcore or is the 7970 just not what we thought it was ?

I cant find it now but i swore i read that quote but i cannot find it this morning could someone help answer my questions?

yes if you have a good processor it will still bottleneck your cpu. its just because its so fast. not because it bad or anything just compared to the cpu its faster then previous gens. theres nothing to worry about.

BF3 is gpu and to a little lesser extend cpu heavy. it is extremely gpu heavy though.

I think @cbrunnem have right because 7970 is the best single gpu on the market http://www.tomshardware.com/charts/2012-vga-gpgpu/13-Battlefield-3-DirectX-11-B-Performance,2968.html

In order for these new cards to shine, you really need a motherboard with a PCIe 3.0 slot. And to take advantage of PCIe 3.0, you need one of the new 22nm Intel Ivy Bridge processors. The current Sandy bridge CPU's do not support PCIe 3.0.

Do you have a link / benchmark that shows the difference in gaming performance when running a 7970 on PCIE3 vs PCIE2. I thought even the top prior generation cards showed little difference between PCIE2 and PCIE 1 unless using SLI. I find it odd that the prior generation had more then enough bandwidth but that the new card is bottlnecked by 16 PCIE2 lanes.

Hopefully soon when Ivy bridge comes we can see some reviews and benches for it , I'm pleased to see the pci-e interface getting upgraded to 3.0 and curious to see what perfromance gains come out of it.

If PCIe 2.0s full bandwidth is not yet utilized, how do you expect for Ivy Bridge to do it on 3.0? And no, you do not need a PCIe 3.0 to take full advantage of the 7970. The PCIe 2.0s bandwidth is enough for getting the most out of the GPU.

@azeem40 have right.
