Sapphire 7950 Scoring Lower to MSI 7950

[The N]

hey guys

i have sapphire 7950 DualX in my Rig. but i am facing interesting difference between two different brands of same card. i ran 3dmark 11/valley/Firestrike on sapphire 7950 but at same Clock rates comparing to my Previous MSI 7950 ,,,,,,sapphire Graphics scoring lowered to MSI 7950, even sapphire clocked even better to MSI. but still the score is about 500-600 lowered.

here is the comparison

(Previous)MSI 7950@1220/1500 mhz Vs. Sapphire 7950@1220/1700 mhz(current)

3DMArk 11

MSI

Vs.
Sapphire

Firestrike
MSI

Vs.
Sapphire

Valley 1.0v
MSI

Vs.
Sapphire

you guys can see a clear and very noticeable difference between both GPUs, I might think its behavior factor, as every unit of GPU Behaves differently. But that factor more comes in GPU Overclocking. some GPU overclocks well some dont. But here Both GPUs Overclocked Equal on Core and Sapphire better in memory overclock by 200mhz. so it should score atleast equal to MSI one. may be cross it.

I just want to know if there is another factor that i am missing??? or there is certaintly a problem while running this card??? OR it is NORMAL??

My Current Specs Vs. Previous Specs

i7 2600K @4.5GHz Vs. i5 2500K@4.5GHz
Asrock z77 Extreme 6 Vs. Same
Fury 8GB 1600mhz Vs. Gskill ripjaws 4Gb
Sapphire 7950 DualX Vs. MSI 7950 TF III
GS800w Vs. Same


Thanks in ADVANCE!!!

The difference has got to be due to the cpu and ram change. Run the benchmarks again with the same cpu and ram and see if there's any noticeable difference.

i am little bit confused. if they are same GPU why are the default clocks different for both cards. 960 for MSI and 925 for sapphire.

My first guess would be you've overclocked the memory on the Sapphire card too far. I can't remember when, but at some point AMD started using an ECC algorithm on the memory of their cards. When you overclock the memory too far and it starts generating error the ECC algorithm kicks in and hinders performance. W1z mentioned this in one of his reviews.

One has a higher overclock from the factory.

3dmark 2011 can be also a difference with the CPU.. physics score.. Faster CPU

but newtekie1 is right, Ram can have ECC, I would drop to the same ram speed (also make sure to use same system driver and same CPU)

But unigine will reflect more, as it is less CPU dependant.

brother, currently i am using i7 2600K@4.5GHz, which is better than i5 2500K(its already sold now) due to more threads. so physics score should be higher which also i am getting low. . One of the factor for better physics score with i5 2500K was RAM. previously i had gskill 1600mhz @7.8.7.24 rams which i overclocked to 1866mhz @8.9.8 timings. it was alrready a faster ram which increased the physics score hugely.

Secondly i have more concern towards Graphics Score. as i am comparing here Sapphire Vs. MSI 7950.

Physics Score
Anotehr point is i7 2600K @4.5GHz(4/8)+FURY 1600mhz, didn't you guys think should perform better against i5 2500K(4/4)+gskill 1866mhz.????

@newtekie1
bro i tried to lower the Memory to 1600/1500mhz and then check. but i am unaware about ECC. if you give some light on it, would be appreciated. or any valid link.

 

[ChristTheGreat]

At top, your 2500k = 4.8ghz vs 4.5ghz but yeah, you should have a bigger score with the 2600k.

does the 2 run are with the same driver? but like I said, try to set te same GPU ram speed first.

Look up core parking

@eidairaman1 @ChristTheGreat

brother i just checked and yes there was 4 core parking in resource monitor. now i disable it through registry config.

so i again gonna compare results this time for CPU only.

Just compare Physics Score

i5 2500K @5.0GHz + Gskill 2x2GB @1866 @8.9.8.24 timings

i7 2600K @5.0GHz + Kingston Fury single 8GB @1866 @9.10.9.35 Timing

i7 2600K score definitely lower, even i overclocked CPU and Rams and tighten the timings as well. only 200 difference not good results. what you guys have thoughts on it.

@The N

Why do you keep creating variables in your system and yet expect to get similar results? You ran dual channel ram with the 2500k and single channel with the 2600k. Why aren't you keeping changes to the system to the minimum if you want to find out if there really is any difference between the gpus and the cpus in these scenarios?

What I mean to say is, you want to test the gpus, you keep the rest of the system the same for both gpu tests; you want to test the cpus, you keep everything else the same for both tests and so on.

I might be mistaken in thinking this is what is making the difference, but it sure seems like common sense to me, or at least it's what I would have done.

Sorry if my reply wasn't of any help to you.

So?. His current setup is better than his previous setup yet he got a lower score.

@SKBARON

bro firstly i clear one thing 4 u. i dont have both setup right now. i am into benchmarking from some time now. so i usually upgrade or downgrade setups as per my will. currently i am doing work on i7 2600K setup. previously i had 2500K .......... unfortunately i sold my gskill rams but doesnt matter alot. i already ovelcocked my current rams to almost same levels. i benched both at their time. now when i bought i7 after selling 2500K i expected to get better score in benching like 3dmark 11 which actually i am not getting.

so my concern is why i7 2600K not drawing full potential/performance outta it, as i have seen on web it scored above 10k in many cases. these forums are here and build for discussions so i thought i might get some help from here. that is why i put a brief my problem through benching screens.

 

[vega22]

software bloat?

single chan ram will not be helping it much either but for ref my 26k used to get between 10.2 and 10.7k cpu score at that speed from what i recall.

 

[Schmuckley]

You gotta mess with the BIOSes to get maximum performance per clock..

ie:You can overclock and get worse performance if it's not set up right.

 

[EarthDog]

So much effort there to not get throttling in a power virus program. For anything outside of that, just raise the power limit...

But someone nailed it. Tough to compare results when its not Apples to apples.

There is a 'bro' overoverkill in this thread.

 

[Aquinus]

For the 2600k system being single channel, this makes complete sense. Numbers aren't more than 5% off and is well within error considering the differences between PCs. I'm not sure what your complaining about. Put the 2600k into dual-channel and run the i7 without HT and it will probably almost be the same numbers assuming everything else is the same.

This and...

This.

Also I saw the i5 running at 1.57v, are you trying to kill your CPUs?

yes i know it is too much vcore on i5 2500K but it was applied to make it stable just in benching run. it wasn;t a cool chip either to overall well on with 1.45v. currently have i7 2600K @5ghz @1.50v , it was a cool chip though i only tested it on Physics Test run.

1.5v will still degrade a SB much like my SB-E CPU. If you're not under water or phase change, you're going to damage your CPU over time with voltages that high. Also you said that this wasn't a cool chip even at 1.45v. It's the temperature that kills it, not the voltage. Higher voltage usually means higher temps.

higher voltage means more heat, which means high temps which ultimately reduce high score, limiting performance i:e throttling. and hows this i manage to get 9300 physics score in 3dmark 11. @5.0ghz. somehow it gave me quite good score i guess.

2500K already sold brother. now i have 2600K. only done 5.0 @1.5v for benching. right now using @4.5GHz @1.34v. i am not long term user of any component. i use to play with CPU/GPU/RAM long time now,

USed 2500K 2x chips and 2x2500 and now working 2600K. but i think i need dual channel RAM for better scoring like over 10K

 

[EarthDog]

Why are yo not running dual channel? And that may not help as much as you think it will...

yeah, you are right. and i already analyse it. let see if i can get another 8Gb stick.
