nvidia 970 vs amd 390 - Page 2

Frankly, I remember even 4.9GHz 2500k with 2133MHz RAM couldn't deal with some of the overhead I remember in FarCry3. The Vaas killing mission made me furious cause I was getting mad stutter and fps drops in the best mission of the whole game, although prior to that moment it ran at 60fps very smoothly. Back then I didn't know what was happening, I thought it was the game's fault. And it's gotta be said that CPU-overhead related fps drops are far worse for your perception than GPU-bound fps drops. Even at 57-58fps the stuttering is unbearable. Back then I was a FC3 nut and played every day, so I know every place where the CPU overhead became evident on my 290. After I bought a 980 I was already bored with FC3 but I did some testing and the problem of CPU overhead was gone. I could literally drop my CPU and RAM to stock settings and the fps drops would still not show up. You might argue that 980 is a tier faster but I bumped the visuals too in comparison to the 290. Another thing, once you encounter a CPU overhead changing the visual settings doesn't help at all. In the FC3 scene I was referring to I could drop the settings from v.high/high to medium and still I'd be under 60fps on the 290 since I wasn't GPU bottlenecked, it was the driver which induced a CPU overhead.
Like I said, if you have a strong CPU like OC'd i5 or better and i7 and fast RAM (that is important for the CPU too) it might alleviate the problem to a great extent, you might even say it's gone. But I wouldn't venture to buy a 390 if I was running e.g. i3 and 1600 memory. If this Venezuelan guy comes here and tries to lure you into 390 by denying every problem that ever existed on AMD hardware, showing outdated benchmarks, remember I told you my personal observations, not some looped up sequence of a game which might still hide a lot of existing problems. I hope I helped.

I know what you're talking about. I have 4770k at 4.5 and 16gb of 2133 c9 ram and going through vaas mission was hell. But at the same time Far cry 3 is known to run rather poorly on amd hardware (personally I think it runs flawless on single gpu 99% of the time except in some areas as you said, most notably in vaas mission. Dual gpu I keep getting CTD once every hour or so but other than that it's fine.).

With a weak cpu I would get Nvidia that's for sure. Anyone denying the amd cpu overhead problem is lying to themselves. Good thing dx12 is here and hopefully all these problems will be non existent in the future.

does ati always beat nvidia at the same price range as nvidia in previous generation ? nvidia 700 series and 600 series ? same price point against each other . like r9 390 price = nvidia 970 , but r9 390 performance > nvidia 970
previous generations ?

280x>960 (within several percent)
390>970 (very close,I'd say almost the same, trading blows in every game)
but:
980>390X (again, not by a huge margin, and the 390x is a bit cheaper)
980=Fury if we compare an aftermarket 980 like G1 or Classified with factory OC (but 980 is cheaper)
980Ti>Fury X (can range from almost the same performance to as much as 30% in favor of 980ti while running overclocked)
The biggest gap between the two is probably how aftermarket 980ti nails the Fury X since one overclocks really well and the other has very little OC room, while the 980ti is already faster than Fury with reference clocks and cooling. 980ti is also cheaper than Fury X.
I'd say the true winners are R9 290 (still biggrin.gif) and 980Ti. My 290 ran 1440p in Dying Light and FC4 like a champ,unless I got some overhead which kind of ruins the fun.
970/390/390X and 980 are all good choices. I would take neither 960 nor Fury/Fury X. All three are kind of disappointing.

If you've got a big enough PSU you can try finding a pair of used 290s, Two 290s for less than a 980 costs (they'll come used tho) is a lot of GPU horsepower/$. If only it always worked like it should.....I wouldn't worry about overhead much tho
I mean check out Bradley's AMD driver thread, but remember he's still running Sandy Bridge CPU, you've got less cores on yours but it's 2 gens newer and tbh games benefit more from IPC nowadays. Get that thing to 4.5 and you'll be fine.

thanks for your detailed listing very easy to understand + 1 rep
and where do 290 stand is not in the list ?
and lastly which would u take 390 or 970 ?

290 is the same thing as the 390 just without the 8GB of VRAM.

If you are buying used a 290 is a much better deal. If you can find them new they are also a better deal. The 390 is a waste of money.

^this. 290 used. Got mine for $240 with a full waterblock.

390 @ 1150 vs 290 @ 1200 . . .

ebay. under $300 is fine to take a chance. supposedly a mining card. The used ek block only cost $60. there should still be some floating around even here in ocn.

Compare graphics scores.

Compare memory clocks. That's why there is a difference in GPU score.

exactly. 300 series seem to use better vram quality and are able to oc higher. could be bios as well. Good observation. Hawaiis top out most at 1600.
