Will a amd fx 8350 cpu bottleneck a r9 290 gpu?

[RowdyNeil]

Need to know for a gaming PC build.

 

[JoneD]

AMD FX 8350 CPU won't bottleneck a single R9 290 Graphics card.

 

[iron8orn]

The 8350 will limit the potential of the r9 290

 

[AMD_Liquidify]

It will not bottleneck. My friend has a FX-8320 at 4.0ghz with an R9 290X and it works like a charm.

Here's a chart of CPU performance. You can see that a 8350 slightly bottlenecks whatever GPU is used (most likely a GTX Titan). So A 8350 will limit a 290, but not by much. About 5 FPS compared to a 4770k.

That is one game.. here is some knowledgeable people running some hard data coming to the same conclusion.

If a R9 290 Doesn't bottleneck on a FX 8350 then it wouldn't bottleneck a A6-6400K because the 8350 isnt that much better than a 6400K

False. The A6 and the 8350 are entirely different chips, thus, you can't make assumptions on the performance of A6 based loosely on what is said about the 8350.

The A6, being a dual core, cannot handle CPU dependent games such as GTA V. There are many limitations the A6 faces that the 8350 can overcome with ease.

Back on topic. I have an OC'ed Fx 6300 @ 4.3 with a R9 290. I have hitting around 60 fps on AAA titles such as fallout 4 and battlefield 4 on ultra preset in 1920x1200p. You'll need to overclock the 8350 to get rid of the minor bottleneck.

Well I have a A6-6400K rn, but Im upgrading to the best FM2 socket CPU witch is the AMD Athlon 860k Quad-Core with a R9 290 and I have watched videos and people seem to get really good fps in lots of different AAA titles? so what do you think

 

[Benjiwenji]

An overclocked 860k will still bottleneck the 290 by a bit. I have a 760k @ 4.6 paired with a 280, and they don't bottleneck each other. In my opinion, the 280x is the best GPU to pair with a 860k @ ~4.5ghz. However, you'll still see excellent FPS with the 290. You will have to overclock the 860k to atleast 4.5 ghz.

Will it do it on a 500watt PSU, because aparently you can it just cuts it real close if you don't overclock the gpu

 

[Benjiwenji]

It depends on the quality of the PSU and the +12v rail. A 290 peaks at about 320w by itself. It is cutting real close. What is the PSU that you're planning on using?

I don't know the name but its the 500w PSU that I have in it with my A6-6400K and I'm getting all my stuff tomorrow

 

[Benjiwenji]

If you don't know the quality of your PSU, then I would highly advise against using it in that setup. It will push your PSU, lesser quality ones are likely to fail and take other parts with it.

I bought a 700Watt PSU 2 days untill its here 😀 just need to order the CPU and GPU

 

[Benjiwenji]

nice 😛

 

[Velinzor]

nice 😛

I got the athlon 860k with a XFX R9 280x with 700w PSU

 

[Benjiwenji]

that's a good setup. OC it to 4.4-4.5 and you're golden with the 280x

Ik Im so excited here is whats going to be my new specs

CPU: AMD Athlon 860k x4 OC to 4.5GHz
GPU: XFX R9 280x 3GB GDDR5 PCIe 3.0
MOBO: MSI-A78M-E35
RAM: 16GB Kingston HyperX Fury DDR3
PSU: Rosewill ARC-700, ARC Series 700W Power Supply, 80 PLUS Bronze Certified, Single
HDD: 1TB Samsung
2 Fishrocket fans and heatsink

What you think Benjiwenji?

 

[Benjiwenji]

Looks good! Did you get a CPU heatsink for the 860k? What model is it?

Listen, bud. Be careful when overclocking with that motherboard.

1.) It has no heatsink on VRMs, so keep case cool by having top and rear fan as exhaust while front and side panel fans as intakes to keep motherboard cool.

2.) Read and watch plenty of AMD overclock guides!!! Understand the process before starting. OC in BIOS, not through a program.

3.) Stress test often!!! (Every time you change the clock speed or voltage) You'll AMDOverdrive for temp reading, CPU-Z for voltage readings, and Prime 95 for stress testing.

4.) I wouldn't go above 1.45-1.5v, increase voltage by 0.01-0.05 increments. Too much can fry the system! So patience is key to success.

Good luck!

No that heatsink was with it when i bought it with the A6-6400k APU Its overclocked to 4.2GHz from 3.9

As someone who spent HUNDREDS of hours and nearly 50 threads on here a year or so ago, let me shed some light here.
In certain titles, the 8350 bottles the 290 a ton, drops it down to nearly 70% usage in GPU bound games (biggest problem was BF games)
In nearly all games you'll see 5 fps loss vs an i7, and maybe lower minimums, but in other games you can see massive drops.
In bottled games I got 10fps less on average and saw minimums 25fps lower than I get now with my Intel.

Here is some actual data I recorded, not just word of mouth here. Pay attention to GPU and CPU graphs as well as usage levels.
In GPU bound games, if your GPU is ever lower than 99% usage with Vsync off, you ARE bottlenecking, and I saw that routinely with the 8350.

If you want me to explain what some of the graphs mean I can, but basically as seen in thhe gameplay, the yellow(CPU) and GPU(green) should be right on top of each other. If one is higher than the other, that part is bottling.

Since I got my 4790k, I don't ever see lower than 97-99%, it fixed any low FPS issue I was having in all of my games (tested nearly 300 games) OVERNIGHT

If you can live with bottled performance to cut money, grab an 8350, but I highly recommend an i5 over one anyday
Maybe Zen will be better???

First of all, your videos are not benchmarks. All the essential information are either missing or done wrong. There are professional benchmarks out there if you're to make an argument or comparison. Obviously, you're having trouble with your system to begin with. Thus, your case is the exception rather than the rule. Start a new thread to discuss your problems, don't high jack this one. Furthermore, if you really want to benchmark on youtube, then start with screen recording rather than a hand held. Also, use creditable software, such as CPU-Z, AOD, MSI afterburner etc, instead of windows task manager. You should post your specs and settings as well.

Second, the Haswell i7s and the Fx-8350 are of different tiers entirely. The 4790k being $240 USD while the 8350 is $170. It is pointless to compare the two. The i7 is hardly worth the money if you're gaming. The i5-4690k will do just fine when games don't generally take advantage of the extra threads.

Who really wants a constant 99% GPU performance especially if running on a 60htz screen??
Its for bragging rights only ,

An 8350+290 is going to push 60fps on 99 % of games if vsync'd at 60-70% CPU & gpu usage - that's enough in my opinion.
