FX-8350 CPU bottleneck?

[ChuckFx]

I am in the process of refreshing my system, I replace my GPU with a new r9 290x and I wanted to know if my FX-8350 will bottleneck it..

The sole purpose of this computer is to play BF4/fraps and other demanding games.

I plan to expand to CF in 4-6months.

OC the chip and it is not a bottleneck.

Will go good with your 290x

If you're going to run something like FRAPS at the same time as your game, the 8350 is a good shout- the extra cores mean you can offload the recording program and still have plenty of cores for your game.

But would the performance with an i5-4670k be better overall?
If I get only a small gain, I'll keep my 8350 for awhile but if there is a major (15+ fps) gain to do, I will change.

It depends on the game. In BF4, I dont think you would gain much if anything by going to a non-hyperthreaded 4670k. In some games more dependent on single core performance you could see a considerable gain.

Overall, I probably would pick the 4670k if starting from scratch, but I dont think it is worth it to move to it if you already have an FX8350, especially if you are interested primarily in Frostbite games that utilize a lot of cores fairly well.

In most games you're going to get much more than a 15 frame difference with the i5-4670k. Take a look at the Ivy-E review on this site and look at the gaming results, the i5 beats the 8350 by 40+ frames in most of the games. There are a few (Tomb Raider) where it doesn't, but it's still a pretty significant jump for gaming. With a high end graphics card you should definitely notice a difference...

Yes

Wouldn't this question depend on how many pixels you are driving? I could see the answer changing if you are at single-screen 1920x1080 vs eyefinity 2560x1600x3.

You should OC your 8350.
Unless you go to an i7, you wont see a huge difference in game FPS.

Although the i5 will dominate anything Single threaded .

 

[ChuckFx]

Well I do want to go dual 1080 screens at same time as my new r9 290 arrives and a 3rd in 4-6months.

 

[Erenhardt]

Here is somewhat accurate comparison:
http://www.anandtech.com/show/6934/choosing-a-gaming-cpu-single-multigpu-at-1440p/8

7970 and 580 tested, but it is not that far from 290x. Multi GPU setups.

Judge yourself

^this. We can help you find data, but you have to make your own decision.

 

[ChuckFx]

I understand that I have to take my own decision but I like to take into account the expertise of more competent people too. From what I see, getting an Haswell will do a difference but not worth the money. I will hold on to my 8350 which is not bad at all and make the jump to Intel (something I Really want to do) in few generations.

 

[NTMBK]

Oh, you already have the 8350? Definitely stick with it! The performance gains from moving to Intel just aren't worth that much money and hassle.

Don't forget that BF4 is getting Mantle, which will supposedly reduce CPU load and make it run better on 8 core machines than it used to.

 

[Essence_of_War]

Yeah if you already have the 8350, I don't see a good reason to do a (relatively) minor upgrade at the cost of a new CPU+MoBo.

 

[AtenRa]

What motherboard and CPU cooler do you use ??? You could OC the FX8350 to 4.6GHz (turbo off) and you will not be bothered about CPU bottlenecks even with a CF 290X.

Not to mention that in BF4 MP, the Core i5 has worse gameplay than FX8350 even if they have the same fps.

 

[BallaTheFeared]

Considering you want to dump $1100 into video cards, and the 8350 is slower with one in pretty much every benchmark on the web the addition of a second card is going to further increase that deficit.

If you sold your current cpu and board the cost to switch won't be that great, and since you're planning to spend $1100 on your graphics cards don't you think it would be a bit silly not to go for maximum performance and not be held back by your processor?


As far as recording goes, the i5 comes with an iGPU which can offload the job from the CPU to the iGPU which directly reduces the FPS impact recording has on your gaming experience.

Top Center is FPS without recording, left is QuickSync with the video playback below it, right is FRAPS with its huge file playing below it as well.

 

[guskline]

I have a FX8350 at 4.6Ghz (21 multiplier x 219 mem bus) and it is really fast. I have a GTX 680 with it. I cool it with a Corsair H100 AIO cooler.

If you already own the FX8350 rig, spend your $$ on a good CPU cooler or ssd.

This is pretty awesome. Just so I understand though, you can use your iGPU to assist in encoding videos on the fly while he games/records? Does FRAPS do this? Or do you use another software to do this? (The MSI Afterburner software?)

 

[BallaTheFeared]

Other software, FRAPS does not do it.

MSI Afterburner does it, Action! has it as well. Some streaming software like Open Broadcaster uses it as well.

Yeah the basic idea is instead of dumping raw format like FRAPS does, or using to CPU to encode on the fly you use the iGPU built into the Intel chips to encode using it's dedicated quick sync encoder.

Nvidia has similar tech with ShadowPlay, AMD does not however for their graphics cards.

The videos I snipped were 104MB for QuickSync vs 6GB for FRAPS...

I thought that Raptr could do that?

Jittery as mad frametimes when using perfoverlay graph you mean? I noticed since bf3 that the game perf wise wont scale beyond 6, but going from 6 to 8 on fx and going ht off to on the frametimes become less jittery, less frametime variance could correlate to a more fluent gameplay experience

 

[Ventanni]

Honestly, you really can't argue that file size comparison alone.

 

[BallaTheFeared]

I think you can stream with it, but I don't know if it uses dedicated hardware on the AMD gpus to reduce the CPU overhead.

I tried to checked quick, but it crashes my games.

I couldn't find a way to just encode to HDD, I'm not really inspired by the software tbh.

LOL what? 240p?

 

[BallaTheFeared]

No, 1080p same as FRAPS.
