Is my X6 1090T bottlenecking my HD6990? - Page 5

post #41 of 85
Well if you do, don't get the H50, it is very overrated and not that good of a cooler. Rather look at the new H100/H80 coolers if you want an all-in-one cooling unit. Or maybe even the RASA kits for a nice easy intro into watercooling.

The x6 processor (or mines at least) isnt at full load on all 6 cores, and all 6 cores are working while playing crysis 2.

That's not bottlenecking.

However, If a sandy bridge works better, than the x6 under performs when compared to a 2600k.

So bottlenecking is just overstating the difference between AMD and Intel. People say that your CPU is bottlenecking you card (99% of the time thats not true, there just some setting they need to fix for optimization) and it makes it seem like their CPU is no good and outdated.

Why is it then, when on the intel board, when people are complaning about sli and crossfire and other FPS problems, people are trying to trouble shoot.

But in the AMD board, as soon as somebody is having FPS problems about 10 sandy bridge owners pop in and yell "BOTTLENECK BOTTLENECK"
Actually, the game can't utilize all those cores. The ones it can though are used 100%. So yes, the CPU is bottlenecking because it can't support the GPU in this particular game. In comparison, a lot of games use 4 cores and since i5's and i7's have 4 more efficient cores, they don't bottleneck as easily. The more efficient cores benefit Intel even more in games limited to 2 cores (StarCraft 2 is a very good example of this). A Phenom II X6 doesn't have the power in 2 cores to support a good GPU in SC2, so by your definition, it's bottlenecking. Technically though, a 2500K will still bottleneck a high end PC in SC2, that game is just ridiculously CPU dependent.

Derp is right, if a different CPU performs better then the Thuban is bottlenecking. It is by your definition.

I'd like to see you say with a straight face that the 1100T doesn't bottleneck the GPU in SC2. No, it's not at 100% load, but it's still not able to support the GPU.

All Phenom II CPUs bottleneck high and dual-GPU setups.

Well, a re-install of Windows fixed the issue for me. Now averaging 55 FPS.

99% load on both GPU`s.

I think from all the reviews I have read the 1090T just doesn't compare to a 2600K in performance. I have the same setup in one my rigs with a 1090T and Crosshair IV plus two 6970s, and slightly disappointed. Heres why:

1. Amd's top cpu can't hold a candle to Intel's top performing cpu (Consumer grade that is).
2. Amd's top Gpu can't again compete to nVidia's top gpu..

Its not just a question of bottleneck but how fast your engine is under the hood and all the other parts installed. Guru3d just released a Crysis 2 high res HD texture pack benchmark and the numbers do not look good for AMD. Not only that is stands to reason they are also over priced!

I learned that the hard way with AMD. They take out good products but the drivers are a let down. They made me a beta tester for 2 years with their crap drivers. I used to have a huge issue in SC II with CFX 5870 XXX. Many people here on OCN said that my I7 920 was bottlenecking which was totally false. At one point I was running my I7 @ 4.4 GHz to find out from the chimp leader, aka Terry Makedon, that they are working on a hotfix for the game. The word bottleneck is used on OCN far too often. If you are using an AMD high end gpu, rule of thumb before you claim to have a bottleneck is to check the drivers.

Yeah I heard that the 11.8 Preview Drivers release some 10 percent extra performance, but your right their drivers can be a let down at times in the past. Seems like lately though they have got their act together..

Crysis 2 has problems with Crossfire.

Yes, a Thuban will bottleneck a 6990.

Yes, Intel is currently that much faster.

Should you care about the bottleneck? No.

Actually learned the word "bottleneck" from searching the forums here, so guess you can say that it`s over-used.

Anyway, Crysis2 is moving along at 70-80 FPS now

Once they have a fix for the Xfire issues, those frames will jump even higher. Keep that card till you upgrade to Bulldozer/Sandy Bridge/Ivy Bridge, and watch the frames open up even more.
