Does the amd fx 8320/8350 get fps drops with a r9 280x?

tensai27 · Nov 16, 2013

It was suggested to me on another topic that I started to upgrade my CPU to the amd fx 8320 and overclock it. I am looking for a processor that is compatible with my motherboard and will not bottleneck/drop fps on my gpu.
Here's what I currently have:
FX 6300 -4.2ghz w/hyper 212 evo
MSI R9-280x -1120mhz core, memory untouched
8gb team 1333mhz ddr3 memory (8gbx2)
ASUS M5A97 R2.0
Toshiba 500gb 7200rpm hdd
SeaSonic S12II 520 Bronze 520W PSU
Cooler Master K280

Does anyone have the fx 8320 or 8350 with an r9 280x or 7970 ghz? How is the performance at 1920x1080? Any fps drops? I'm looking for a smooth 60fps experience at 1080p on high/ultra settings. I would really appreciate any info before I go out and buy a replacement for my cpu. Thanks!

I have an FX8350 with a HD7970 ghz (Sapphire Vapor-X), with no OC on either one. The only thing I've pushed it with is Skyrim with high res texture packs and ENBs, and it stays a 55-60 frames (and Skyrim prefers Intel chips).

Interesting, thanks for the reply. Isn't the amd fx 8350 essentially a factory overclocked version of the 8320? If so, I would probably opt for the 8320 and oc it myself to save a little. I'm getting massive drops in sleeping dogs while driving during the day. Have you had a chance to play that game? I also get some fps drops in BF4, farcry 3 and arkham origins. Also, what speed is your ram?

If you're comfortable with overclocking and looking to save a few dollars, the 8320 is the way to go.

I can't help you with the games, I don't play those.

I use 1600s (G-Skill Ripjaws X Series).

The 8320 is a lower stock clocked 8350 yes. You probably wouldn't see too much change from upgrading to it from a 6300 though.

Just get the 8350 , not worth skimping in this and day age... its a beast for the price smh

JOOK-D · Nov 16, 2013

chromex :

The 8320 is cheaper and most can reach 8350 speeds with just a multiplier bump... why spend extra?

tensai27 · Nov 16, 2013

If there isn't much of a change then no sense going and spending all that money. I bought this amd fx 6300 cpu 4 months ago so if the 8320/8350 isn't going to give me an improvement, it seems foolish to buy it. What about ram? I'm running 1333mhz as seen here http://www.overclockers.co.uk/showproduct.php?prodid=MY-023-TG

RAM seems fine. Higher RAM speed doesn't make that much difference at the moment, not enough to warrant the amount of money you'd need to spend to get a new kit.

JOOK-D :

Yeah, I've seen the benchmarks. I noticed you have the 8320, do you experience fps drops in games?

Depends on the situation. In single-threaded games it can often drop below 60.

tensai27 · Nov 16, 2013

I looked into it and the fps drops that I get during daytime in sleeping dogs are happening to lot's of people(even people with much better hardware than me). It's a problem with the game engine. Night time plays perfectly at 60fps but daytime goes all over the place.
I realize now that the 8320 is pretty much the same thing as the fx 6300 + 2 extra cores. The performance gain will be minimal unless the 2 extra cores are being used. Since most games on the market use 2-4 cores, it seems silly to think that the fx 8320 will solve my problem. Everyone I have asked in this thread and others, generally said they had good performance with the 8320. I noticed however, those people all happened to have faster ram than me. After doing some research, I have found that the FX chips respond very well to faster ram(1600mhz and up) and upgrading my ram might actually be the key to smoothing out my performance in some games. Keep in mind, I'm not playing old games, I'm playing much more demanding titles so it's reasonable to assume that those games would take advantage of faster ram. I appreciate the help, I will report back after buying faster ram in hopes of helping anyone who has a similar issue as me.

I was thinking of getting this: http://goods.ruten.com.tw/item/show?21311094810785
It's reasonably priced, any opinions?(Sorry if the site is in Chinese but I'm in Taipei. Still easy to figure out without being able to read it.)
Update: Found an English page: http://www.amazon.com/Kingston-Modules-1866MHz-KHX1866C9D3K2-8GX/dp/B0055ZEKC4
It's cheaper here in Taipei, probably because it's made here. That amazon seems like a rip-off but you get the idea.

JOOK-D · Nov 17, 2013

I have the same RAM but @ 1600mhz. It's decent.

JOOK-D :

This, worth saving money unless you have enough to get the 8350!!!!!

tensai27 · Nov 17, 2013

sora :

There isn't any point in buying either for me if I already have an fx 6300 at 4.2ghz. Most games don't even utilize 6 cores. Right now I am looking for something to reduce fps drops but I am almost certain that the fx 8320/8350 isn't the solution. Thanks for the input though.

tensai27 · Nov 17, 2013

Here's a question: What if I upgrade to the 6350? I'm pretty sure my psu can handle that. What would my chances be of reaching a higher overclock than I currently have? I'm almost tempted to do it since the only way I could get an i5/i7 is if I bought a new motherboard. It would be almost funny though if I only got up to 4.2-4.3ghz on the 6350 oc though.

JOOK-D · Nov 17, 2013

No I don't think you'd get a much higher OC, definitely not enough to warrant the spend.

And I agree, it would probably only be 0.1ghz or so which is the same as the 8320:8350 OC ceiling.

tensai27 · Nov 17, 2013

What the.... Found the solution on my own guys but let me share because I would like to save people the trouble of not going what I went through. HPC mode, I don't know if it will work all the time but on my motherboard at least fps drops are 100% gone with it enabled. I just fired up bf4 and loaded a map that gave me drops and even the most intense scenes stayed consistent. This really had me scratching my head, it seemed weird to me that people suggested an overclocked fx 6300 for gaming when it did this terrible. Now I get it, even though I found out the solution on my own, I really appreciate the time you guys took to try to help me. Thanks!

JOOK-D · Nov 17, 2013

tensai27 :

Select yourself as best solution if you can!

Also did you enable it or disable it?

EDIT: For future readers of this thread http://www.tomshardware.co.uk/forum/273947-29-what-mode

Toggle HPC mode.

tensai27 · Nov 17, 2013

I had it disabled and was getting the fps drops. Enabled it and problem solved. Not sure why....

JOOK-D · Nov 17, 2013

Weird according to the other thread haha. Well, just toggling it would probably help. :lol:

tensai27 · Nov 17, 2013

You know what is funny? That is the exact same thread I saw a while back which made me decide to disable it in the first place...guess it wasn't helpful in my case.

tensai27 · Nov 17, 2013

Actually just noticed they recommend to enable htpc mode on this guide: http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard
"HPC Mode - Recommended - Enabled - Prevents Throttling when Socket Temp gets high. (In some cases it may cause freezing - if this occurs its recommended to disable)"
Anyways, all I can say is it did the trick for me and if anyone else has fps drops on the fx 6300 or even maybe another fx cpu, it's worth a try.

tensai27 · Nov 18, 2013

Update: Sleeping dogs daytime fps drops are gone too! Even when driving. All this time I thought it was a broken game engine. Unbelievable. Borderlands 2 stuttering and fps drops are also gone when playing maxed out.

Does the amd fx 8320/8350 get fps drops with a r9 280x?
