Will my fx 8320 bottleneck a radeon hd 7970? - Page 19

I actually own a 8320 that'll go fast if I want it to but I'm also very much willing to admit that it can't compete with intel setups when using multiple high end GPUs.

how about per dollar spent?

an 8350 can keep up with a 3570k, I am happy to admit as well that a 3930k and a 3770k are better than a 8350, but against a 3570k which is where the 8350 is priced, i'm sorry having done the benchmarks and seeing it with my own eyes rather than relying on a sponsored review site, I would take an 8350 every time.

3. 2500k is "bottlenecking" too, it is quite far behind the 2600k/3930k.

4.Every tested cpu is at stock-clocks, who the hell is gonna buy the GTX690, use a single 1080p-screen, and pair it with a 3,3GHz processor? Ofc there is going to be a bottleneck, if you OCd 2500k for instance to 4,5+GHz, results would be more "real". Yes, it is a good way to highlight the bottleneck, but isnt really useful when trying to create real-life scenarios.

5.It doesnt include the FX83xx (like said) and also it is POSSIBLE, that their AMDs had some throttling issues caused by cheap-ass motherboard (FX8150 is an eight-core afterall and C3 is a multithreaded game, I remember my 1055T started throttling in BF3 at 3,3GHz when I had an cheap Asus mobo....)

Trying to be unbiased here, just what I found out when I looked at that chart...

a 3570K will match the 8350 in games that are GPU bound and beat it in ones that are CPU heavy.

And as for dollars spent, don't really care about a few dozen bucks when we're talking about multi GPU setups.

Or do you want to go into the ASUS M2N-SLI owners club thread and tell them that the Phenom 2 CPU's they're running on unsopprted boards is performing lower then it should? Because they'll all disagree with you.

Motherboard affects overclocking and features, not performance.

And in your book? I would think that I wouldn't have to address such none sense in the first place.

1. And? The Intel chips are running the same Beta code

2. And? The Intel chips are running the same settings as the AMD chips

3. Never said it wouldn't

4. Stock clocks? The FX chips can't beat the lower clocked Intel parts.

5. VRM count doesn't matter, you should know that.

Trying recording that video on Skyrim or Crysis 2

If there was no bottleneck with AMD chips then they would be kicking out the same frame rates as the Intel chips do regardless of what game it was or how many GPU's you have.

But that's not the case, there's more then enough reviews, articles and user submitted data that show FX chips can in some games perform much much worse then the Intel stuff does.


7870 and FX-8120 all on stock settings, maxing Skyrim on everything maxed out.

Were is the "Try to record" now? lol.

(Even though i have massive problems with the GPU ROFL).

EDIT: It's not maxed out on Anti-Aliasing i think.. Not sure, i think i had probs with my old GPU. (Had bluescreens and helicoptersounds with it, that's why i gave it back to the distrubitor).

Not the biggest fan of Linus but this is the most relevant test I could find within a few mins. Crysis 2 and 890FX vs 990FX comparison. The 990FX chipset allows a 1100T to perform 10% + better here and he used high end mobos (CH). This gives me a reason to believe that a cheap 790 (even older chipset) board may actually hamper a bulldozer badly without even exploring potential throttling.

Yep that and it is commonly known that 4+1 phase control is not to good for the fx 8*** processors

I think most of these intel trolls havent had first hand experiences with these " bottlenecks ". Because most of them just look at benchmarks and assume AMD is crap. I could GUARANTEE YOU if you played on a rig with 7970/680 and a 3570k/8350 you wouldnt see the difference.

Motherboard type and VRM's greatly effect CPU performance.

There's been a ton of issues with people buying boards that don't "Officially" support 8 Core CPU's within a certain Range. Everyone who tries to run a 125W rated CPU on a 95W board has crashing and throttling issues. The same is true for the Phenom II X4's and X6's.

Are you saying that if I run one of those cheeop AM2+ Gigabyte boards in that review with the Beta BIOS and an Phenom II X6 running DDR2 800 Ram and a GTX 690

that I'll have the same performance as with an Asus Crosshair IV Formula with official support on AM3, DDR3 1600Mhz, and a GTX 690.
