Why is gaming performance worse with my FX-8320 than my old i3 2100?

Hi

I am a bit confused as to why my new system is worse in gaming than my old system, specs are below:

Latest System:
AMD FX-8320,
MSI 7850 1gb OC,
8gb DDR3 1333,
60gb SSD,
1tb hdd,
Asus M5A99FX PRO R2.0 Motherboard.

Old System:
Intel i3-2100,
AMD HD 6770 1gb,
8gb DDR3 1333,
60gb SSD,
1tb hdd,
Cheap Foxconn motherboard.

I built the latest PC believing I was going to start doing more video and 3d rendering but I really haven't and the rendering times haven't been much better :(

i have noticed the latest system is slower to start up than the old system and when basic multi tasking it is slower to react.

But in games i have noticed generally the FPS has been lower on the new PC even though it has a more powerful CPU and GPU! although it is more stable, so frame rates don't jump up and down as much but the frame rates tend to be lower. e.g. latest system will hover around 60fps on say skyrim where as my old system would be between 30 and 90 on skyrim.

why is the performance more stable but lower?

would it be worth swapping 8320 for something like an i5 for more gaming performance?

the 8320 is better with online games, i guess this is because of the more cores, would and i5 be better though?

I'm likely to change my current case and mother board early next year for a Mini ITX Case to save space and the motherboard is far better than i really need as i don't have multiple graphic cards, so should i change the cpu for an Intel Core i5 3470?

sorry for the really long post!

Thanks

sure it will help, since you got a quality motherboard and a decent cooler, 4,2-4,4 ghz should be possible.

just found this, you cant disable vsync in skyrim ingame, so you are stuck at 60fps, this should help:
Disable Vsync
Access the SkyrimPrefs.ini again and add iPresentInterval=0 to the bottom of the [Display] section.

See AMD has multiple cores with are weaker... While intel has fewer cores which are stronger...AMD FX CPUs do good when overclocked and are good in multi-threaded tasks... But in multi-tasking Intel wins... In gaming also, in older games Intel gives more FPS while AMD does not... In newer games like BF4, AMD and Intel performs same as BF4 uses multiple core which is provided by AMD and due to Intel's solid cores are also good...

You can get Intel Core i5 3470 for better gaming but I suggest you to overclock the AMD FX 8320 for better performance... AMD FX processors do good when they are overclocked... So I think you should first overclock your CPU then try gaming and if gives you good gaming performance(as per you) then you do not need to buy i5 3470...

One thing, which cooler are you having for CPU? Is it the stock one? If yes then change it to a aftermarket cooler... I recommend Cooler Master Hyper 212 Evo... And then only you do overclocking...

That build should be faster.
Make sure you have all the latest drivers installed and that you did a fresh install of windows.

As for Skyrim it can't use the 8 cores on that CPU and tends to run faster on fast dual cores.
It is also highly optimized for intel.
Most games should run very well on that system:)

Personally I'd be happier with a stable 60 than 30-90 though OP...

If you wish to swap to an i5 you'll need a new motherboard and probably a new copy of windows too if yours is OEM. So no, I wouldn't say it's worth it. Skyrim in particular, as jay said, performs much better on intel. I believe there are some tweaks you can do to get skyrim to use more cores, but I've completely forgotten. Also, overclock that 8320 I wasn't happy with mine at stock (only turbo'd to 3.7) so I OC'd to 4.2 and was happy. I'm at my limit on my board with 4.4 though. If you don't know how to overclock: http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard . And only do it if you have a decent aftermarket cooler, I'd avoid it altogether if you have a stock one.

Hi

Yeah I have a Cooler Master Hyper 212 Evo, so overclocking is possible! Maybe the reason I feel the PC isn't as fast I expected is that because I thought moving from 2 cores to 8 was going to be a massive difference in performance, but most programs still run from 2 cores!

I am thinking of changing my case at the moment to a Mini ITX case to save space, this would mean i would need to down grade my mother board, so I thought selling my CPU and Motherboard would pay for a new i5 and mini/micro motherboard which could also lead to me getting better performance!

Okay if you still want to get an i5 you can get... But If I were you I would stay with 8320 overclocked... Programs which appears to be giving low performance in AMD FX can give better performance if the CPU is overclocked...But it is your decision... You can go with a i5...

**My suggestion- I prefer ATX motherboards much from the micro/mini motherboards...**

Hi

Thanks for your response, your probably right in the fact I should just overclock, I will start reading up on overclocking and give it a go sometime soon.

All things the same, the i3-2100 should be absolute destroyed by the 8320.

The 8320 has 3x's higher passmark score, 2x's higher cinebench, 2x's higher geekbench, faster cpu, SIGNIFICANTLY MORE CACHE, overclock capability smokes it, literally every spec is significantly higher then any i3, much less the 2100 (except for the intel fanboi cry of "single core performance").

You should see appreciable gains on everything you're doing in an x86 environment. If you're not, something is most likely not proper.

No way man, compare his entire rig to the old rig. Theres no way in hell he's getting lower fps unless something is wrong.

Yes I agree with bouncedk... AMD FX processors do good in new games and do okay in older games as the older games demand less cores... The INTEL gives more performance in older games and AMD is near to equal performance with Intel in newer games...

See overclocking your CPU if it helps regain more performance... It should definitely do that... :)

He went from a 6770 to a 7850... thats HUGE. That card is SIGNIFICANTLY better then the 6770, theres no way the 8320 is throttling back "worse' performance on a 7850, even in stock settings. The single core speed isn't THAT much slower. No matter how good the intel, that 6770 should have been limiting fps.



I was speaking purely of his GPU upgrade, its MASSIVE.

See, FX processors do up to the mark if they are overclocked... At stock settings they give less performance then they should give... Yes he has a good GPU but still he would feel bottlenecked somewhat with his performance due to stock FX processor... But he would find very good performance if he had overclocked his FX processor... In multi-threaded tasks AMD is better and in single and some multi-threaded tasks Intel is better...

Correct... Overclocking fx processors give exact performance it should be giving... And that performance is good...

nu wtf pentium 8086 iz wey fastr dan ef ex 8350

*Cough*

I'll mention that Intel's compiler will butcher any non-intel CPU's performance. The 8350, when in use with a program made with intel's compiler, will not even touch an i3 2100.

Conversely, in a program compiled with GCC, an 8150 will trade blows with intel's best i7; nevermind the 8350.

In rendering its fine just while gaming it seems less powerful than my previous system

I have just noticed I have been an absolute retard, I'm playing on ultra when I used to play on med-high, thats why the fps is more stable at a solid 60fps.

What should I be able to overclock my 8320 to so it is stable and doesn't increase much in heat? Will overclocking help increase my FPS and rendering times?
