I don't think so. Definitely would of heard about it since I did a lot of research into 5800 series before I bought my card.

If anyone can prove otherwise, please do. Would like to find out that I can unlock shaders, but people have been flashing to 5870 BIOSes on their 5850s and I've yet to see shaders unlock, only increases were to stock voltage and core speed, no extra shaders.

--Edit--
Could OP add in the Call of Pripyat benchmark and maybe BFBC2? Would like to see more gaming benchmarks than just Crysis, sorry. tongue.gif

I do have BF:BC2 so I can bench that when I have time.

The HD 6950's and HD 6970's use the same PCB and everything, only difference is the disabled shaders.

The HD 5850's and HD 5870's have different PCB's and I actually don't think there are any shaders to unlock on the HD 5850.

BTW it's "would've", not "would of".

Awesome writeup, kinda defeats the point of shader unlock, but still the satisfaction remains. smile.gif

Wow nice tests.

It'd be great if someone could do a HD6950 unlocked against HD6970, to see if they are really the same stuff.

6970's have binned Cayman GPU's, different higher clocking memory chips and slightly different PCB to handle higher voltages.

  • My locked HD 6950 overclocked to max performs the same as a HD 6970
  • My unlocked HD 6950 overclocked to max performs 3% better than a HD 6970

Perhaps one more things to add is:
  • Unlocked HD 6950 overclocked to HD 6970 speeds performs the same as a HD 6970

I suppose, the hype is not only about the % gain in performance but is also about the saving the difference between the prices of the 2 cards. In other words, the quotient (Performance gain / Cost saved) gives a good satisfaction.

I wonder, if possible, you have looked into the Power Consumption issue as shown in the Table under Testing in this TPU's article:

Fantastic write up! Made everything pretty darn clear for me, I was tempted by a 6970 to replace my GTX 470, and now, I really may just stick with my 470. I get almost the same FPS in Crysis Warhead! I don't see the point in spending however much more that card is than mine (I'm in the UK) for 5-10 FPS increase.

Saved me some money, so rep for you biggrin.gif

Unlocked 6950 performs the same as a stock 6970. Without having to increase voltages.

See my sig link for *a basic test* on the above statement smile.gif
