CPU slower than old one.

TheShaun · Apr 30, 2016

Pc specs:
Windows 7 Ultimate 64 bit
Motherboard - ASRock 980DE3/U3S3
Processor - AMD FX-4300 3.8GHz Quad-Core
Power supply - EVGA 600w
Graphics card - Sapphire Nitro R9 380

My processing speed is waaaaaaaaaaaaaay slower with the new cpu. The old one was a triple core around 2.something low ghz.Motherboard's BIOS has been updated, all drivers updated, everything updated, defragged, ccleaner used for both registry issues and cleaning. So what could be causing this? What am I missing?

Was your old CPU an Intel?

Archaic59 :

Intel has no triple cores. This must have been a Phenom I, II, or Athlon II, which could very well have played the game better than the FX-4300 due to higher IPC and more FPU power (if the game is not AVX aware).

Had a similar problem and a bios reset fixed it for me

damric :

Yeah, I believe it was a Phenom II. Though, it's not gaming where it lags. I used to have a lagging issue in games too but I solved that by shutting down my pc at least once a day. Now it only lags for non-gaming programs. Only other detail I remember about it was it was not an AM3+ because I had to get a new motherboard(the ASRock mentioned in the specs) for the new CPU. I didn't realize though that the new CPU being twice the price of the old one would end up slower. I didn't do any research on that because I didn't think it would be logical for something being an upgrade and twice the price to be inferior. To make sure I am understanding you and what I just briefly researched about IPC and FPU, my best course of action would be to research a replacement for the new CPU, correct?

Phenom II were and are superior core for core vs FX, the only true upgrade to one minimum is the FX 8350.

A 4.3ghz Quad Phenom II will dust a 5.3ghz FX 4300.

TheShaun · May 1, 2016

MushBrain :

So I should get a new Phenom II? Or is there another brand or type that beats them both in price and speed?

MushBrain · May 1, 2016

TheShaun :

I would not go AMD at all if buying new, i would grab an intel core i3 6100 and a H170 mobo.

Massive upgrade.

TheShaun · May 1, 2016

MushBrain :

I can't afford to upgrade both. I only need enough to run video and image editing software a little bit faster. Not the speed of light or anything, just enough that it doesn't lag my browser when trying to search for images and videos while the editing software is open. I am hoping that can be accomplished under $100.

damric · May 1, 2016

I would suggest some very light tuning/overclocking since neither your board, cooling, or CPU are really designed to handle that, but it may help. First I would adjust power settings in Windows to force all high power settings, then shut off all the power saving in BIOS. IF that's not good enough, then perhaps a light overclock to about 4.14-4.2GHz.

I expect this isn't a CPU problem. Even an older AMD dual core should feel plenty fast in day to day tasks. I think what you probably need is a solid state drive (SSD).

TheShaun · May 1, 2016

Since multiple people say it's the CPU, that must be the issue. Since damric was the first to give reasoning as to why, I guess best solution goes to them. I won't mess with overclocking though cause I do not know enough about it. My only option is to find an upgrade within my price range. Ty damric. Now I'm off to find out what the best compatible processor is for under $100.

Ecky · May 2, 2016

The FX chips might have slightly lower IPC, but you have more cores and higher clocks. At worst, I'd expect the performance to be about the same. An FX should not be "wayyyy slower" - that implies something is wrong.

damric · May 2, 2016

Ecky :

This is a good point. SSD can make even the most sluggish system feel so much faster.

If going to spend money, this is where I would spend it first if you are still on a mechanical drive.

I would not pour any money into the AMD money pit at this time. The technology is just too old to be bothered with unless you can ebay something used for dirt cheap.

I just googled some short info on SSDs as well as a page on pros and cons and I agree, from what I have already learned so far on related information, that it sounds more plausible. I'll give that SSD you linked a try. So, does this mean best solution should actually go to Ecky since he first mentioned SSD as the possible answer?

I don't mind. If it works, you can certainly give it to him.

There is not a single old phenom 2 CPU that comes even close to matching a 4300 on single core or multi-threaded performance.

Your issue may lie with picking that cheap ass motherboard in all honesty.

You need to do some more testing to make sure the CPU is running OK under load - it may be throttling for one reason or another , some of these old boards like you have tend to be massivelybover zealous on their power management.

You changed the motherboard same time as the CPU??

Assuming you didn't clean reinstall windows ??

If this is so then it may be your issue entirely, old driver remnants can cripple performance.

MushBrain · May 3, 2016

madmatt30 :

You are correct, Old Phenom II demolishes the 4300.

madmatt30 :

Yes, both were installed at the same time. No, didn't reinstall windows. I know the motherboard was cheap but I needed a new one for the new GPU and everything I looked up said motherboards weren't much of a deal as long as they are compatible with everything else. Also, I assumed it would at least be better than my old one(which btw was a ECS GF8200A black series).

CPU slower than old one.
