(AMD) my new cpu scores lower than my previous.

Today I replaced my old Phenom II x4 840 with an AMD FX 4130. The new cpu compared to my old, runs 600mhz faster stock, has an l3 cache unlike the other, and is much newer. After my excitement was over and my pc was booted, I reran the Windows Assessment test and much to my surprise, my cpu score went from 7.3 to 7.2. I figured this was just an issue with that and I ran 3dmark. My overall score dropped almost 400, and the physics score dropped by 1000. In confusion, I went into the bios and disabled c1e, c6, and APM. Re ran the tests and still the same speed. The processor is always at the stock speed and is unparked, so why is it slower exactly? Is it maybe just slower in certain operations, or do I have something set wrong. The temperatures are also very good, 55 c average under load and 30c idle. I ran passmark performance test and I score 4185 for my cpu. The reported score online by passmark for my cpu is 4194, so that is good. Any explanations and ideas for the lower scores? thanks! I also found two hotfixes for the bulldozer architecture on windows 7 and installed them but still no difference.

 

Propus has slightly stronger cores than Vishera architecture. Thats why the Phenom 1100T is still next to the fx 6300. Still its a fair bit stronger than your previous cpu.

Really weird.

Could you check with actual games? If it runs better in games I think its negligible.

 

So should I not worry about the 3dmark and windows assessment score? Will games still run faster and better, or did I basically pay to downgrade? I dont understand how it could be slower, with a faster frequency and L3 cache.

edit to respond to your edit: I dont really know how my games ran before fps wise, and i dont think it will be a visible difference.

 

Test it, if its actually slower then I would RMA it.

 

i'd hate to RMA it. Ill just hope that 3dmark and windows arent being very accurate.

 

Tbh I think you were better off with that phenom. Bulldozer was a flop on release.

 

Ok, so I ran Passmark again and better analyzed the results. I saw a Phenom II x4 955 on the chart so I assumed that is a bit better than my phenom ii 840 was. Turns out on two or three tests the x4 did a little better, but the rest of the cpu tests, my 4130 did better on. I guess the 4130 just wasnt as good on the particular load it was put under in 3dmark, but its better at other sorts of things. Not bad then?

 

Singlecore is indeed a bit off compared to the Phenom2 but not that much, especially if you oc a bit. What is your cinebench score? (both single and multithread)

here some benches:

Here are my benches:
Cinebench 15.0
single 86
multi 264

Passmark Performance Test cpu 4940

 

In a way it was a sidegrade at best, and equal performance typically. Unless you clock it up very high, it'll not be very fast. If you had gotten a FX4300 or better yet, the Piledriver 3M/6T models, then you'll be set for most games and applications. Can you see if you can return it for a better model? I've tried playing a number on games with an A8-5600K + discreet card, even overclocked its too slow in CPU dependent games like BF3/4, SC2, Watch Dogs (these were the only heavy games I tried on it), causing FPS dips below 30 very often.

 

Yes, sad to say but the 4130 is kind of weak. A 4300 or much better, a 6300, would work better. All of the quad core FX series are underwhelming but the 4300 and 4350 are the best.

If they won't take it back, you could always sell it on eBay and recover some of the cost.

 

If it were me I wouldn't go no lower than fx 6300 as far as the FX line goes because the 6300 is pretty cheap and pretty good budget CPU.

 

As a 6300 user, I would agree. It's a very good CPU for the price and a lot better than any of the quad core offerings.

 

Your two main problems here are:

1) You bought a Zambezi core FX processor instead of Vishera which is SLOW. Piledriver is a marked improvement over Bulldozer.
2) You bought a quad core, when it would be highly recommended to get atleast a 6-core. The power in the FX processors is in the multi-threading.

My recommendation is to return the processor if you can, and get a Vishera (Piledriver) based 6 or 8 core. Bare minimum AMD FX-6300.

 

Hard to judge what the results will be with just specs, I suppose.

 

Amd cpu purchase

I KNOW THIS IS WAAAY LATER BUT FOR FUTURE READERS I ALWAYS GO TO CPUBOSS.COM before I do any cpu buying. It is a wealth of information, not always written in stone, but gives you enough info to see what you are getting into. If you had used this before purchasing the fx cpu it would have told you they are about dead even in performance, and actually costs you more to operate due to higher wattage consumption. Newer isn't always better lord knows I have found out the hard way many a time:bang: It also has GPUBOSS.COM and SSDBOSS.COM now too:banana: Happy puting!!!!
