CPU bottleneck ?`

[almighty15]

Guffaw.

Similarly, if people now have 7990's to test with I'm sure we can work out what card does actually bottleneck the FX83 if at all..

I was thinking a 260 would compliment it well. I didnt realise two 7770's are not far behind a 7950 meaning only a card around the 7970 (or better) is a worthwhile 'upgrade'.

The FX8350 will DEFFO bottleneck a 7990..

My 4.8Ghz 2600k holds back my 7950's in 80% of all the games I have.... Odd exception being Crysis 3 and such.

7950's in CF or a 7990 is an awful lot of power...

There are plenty of games where there will be no bottleneck at all with an 8350 and 7990. It all depends entirely on the game, the CPU is perfectly able to push the GPU to 100%.

There's probably more games it'll bottleneck than games it won't though (Given the amount of decently threaded games are in the minority)
Not that the bottleneck renders the games unplayable.

Simply addressing the casual misinformed dismissal of the 8350.

I don't care myself if my GPUs are at 20% or 100% as long as I'm getting the frame rate I want, and since I use vsync, it's 60fps.

60fps V-sync isn't the variable you should be looking at..... It should be how often it drops off V-sync when the action heats up.

My old Phenom 2 x6 for the most part would run Crysis at 60fps V-sync but it dropped like a bitch during fire fights. Just like it did in loads of other games, minimum frame rate is much more important then running an average of 60fps.

And while a 8350 might handle 60fps V-sync I can guarantee you they'll be quite a few games where it will not be a rock solid 60fps V-sync with no dips.

This is true, although the list of games using 6+ threads is growing. Some of this also depends on the resolution being used. At 1440p+ it is less of an issue compared to 1080p. With Mantle, even less of an issue theoretically.

Yeah, I tend to talk about 1080p as that's the majority resolution.

The list of using 6+ threads is probably around 20 games (But even using 6+ threads on that basis doesn't give the whole story, as it might need 2 main threads etc and the other threads are for music etc.)

 

[teppic]

The direction is certainly towards GPU limits - a year ago few people would have wanted more than a 7970 at 1080p, but now two of them can't fully max out quite a few games (Crysis 3, Sleeping Dogs, Metro Last Light, even Batman AO).

 

[Martini1991]

With all the raw power we get in GPU's, we're increasingly losing efficiency, ergo, the IQ gain is dwarfed by the power needed.

 

[teppic]

Hopefully Mantle will save us all.

Nah I'm not counting my chickens but in this case would love to be proven wrong
