There is a 15% difference in clock speed in those benches. There is NOT however a 15% difference in performance. 3 - 5% clock for clock is an understatement. In fact, 5% is the minimum. In some games, the performance is more like 15% clock for clock. It all depends on the game.

The HD 7950 boost in stock settings does not run at 925 Mhz because of powertune throttling. max the power option to +20% and it will run constantly at 925 Mhz and then compare with a HD 7970 at 925 Mhz. The compute benches will definitely show a difference more than games because performance in those benchmarks scales directly with number of shaders. But real world games don't show more than 5% at the same clocks. there are benchmarks posted by bruennis which confirm its even lesser at times. if you want ask him and he will bench any game for you.

plus, 7950 with Boost is slower than 7950@900Mhz. It's about the same performance as 7950@860Mhz

its actually amazing looking at these benchmarks and looking at the benchmarks with the new drivers, quite a remarkable difference

Clock for Clock and risking that 7950 dont overclock that well compare as a 7970..

It is a bargain most people are willing to take..

as me i wouldnt change my 1300/1950 7970 for @ 7950 XD
post #17684 of 38704
Just picked up a Diamond 7970 from Newegg for $379. I received the 6 free games, which was a pretty big perk; hitman, Deus Ex, Dirt Showdown, Nexiuz, Sleeping Dogs, Farcry 3, and 20% off Medal of Honor . The construction seemed pretty nice and uses a typical reference design. Going to order some Heatkiller backplates this week and hopefully a CPU cooler as well. Wife is going to snag the waterblocks themselves for Christmas, so I should have the system underwater around the new year and overclocking nicely. Right now I m on two monitors @ 1680x1050 and the card just falls asleep with everything maxed. SC2 was cracking me up with 200+ fps. Within a few months I should be picking up a 2560x1440 monitor and if I can swing it 120hz as well.

at average a 7950 OC around 60mhz less than a 7970 at average, source HWbot.
so all equal the difference is likely less/more than 5%.

You'll need 2 7970s minimum to do 120fps @ 2560x1440 if you manage to swing a Catleap 2B

Like I said it depends on the game. I highly doubt he has benched a stable of games to the extent of Anandtech or others. To form an opinion purely upon 1 user's benches, those benches need to be not only entirely on the same config and setup, but a bare minimum of 15 titles is required. Forming an opinion on 3, 4, or 5 games is fine, but it's not going to stand up as well as benches done by reputable reviewers with stables of games in the dozens.

As some have said above me, I've yet to see many 7950s OC as well as most 7970s do. I own 7 7970s, and I've owned more than that in the past total, and I've yet to have a 7970 NOT do 1200mhz when given enough volts, on AIR. With over half doing 1250mhz, and 3 doing 1300mhz. 2 of them will even push past 1.3ghz, up near 1330. I would happily take my 7970s over 7950s, especially since the prices aren't too far apart. I've obtained 7970s with warrantys under $300. You can't really argue against that rolleyes.gif

Off-topic a bit

Hi guys, I need help with something I'm not familiar with my MSI TwinFrzr Radeon 7950. 2-3 months ago, I bought this card, and it worked perfectly, but as soon as I launch a game, WoW, D3, I can hear a noise coming from my GPU. It didn't bothered me at first, but I still ended up RMA the first card. Then, they sent me a new one, and I still have the same problem.

When idle, the card doesn't make a sound, but when I start a game, it's noisy as hell. It's like an electrical sound or something, I don't know how to describe it.

Yes, drivers are up to date.

Here are my specs:

Summary
Operating System
Microsoft Windows 7 Ultimate 64-bit SP1
CPU
Intel Core i5 2500K @ 3.30GHz
Sandy Bridge 32nm Technology
RAM
8.00 GB Dual-Channel DDR3 @ 670MHz (9-9-9-24)
Motherboard
ASUSTeK COMPUTER INC. P8Z77-V LK (LGA1155)
Graphics
DELL U2312HM (1920x1080@60Hz)

Hard Drives
112GB SanDisk SDSSDX120GG25 (SSD)

Any help? Sorry if I'm not in the good forum.

Quick question!

I got Trixx working PERFECTLY! As opposed to the mess that MSI AB is... so I was wondering if anyone has found an unsafe voltage to put on the cards? Since now I am able to go up in voltage with Trixx, I'm sure I can OC more.

I'm gonna try doing 1300/1900 with 1.387v and 1.8v...
