This is really excellent pricing if the rumors are true, since these cards will be very similar to the 6950 and 6970 in performance (ATI has been a bit modest with their transition charts from what I've seen). Those cards can be found for around $240 and $350 respectively. Oh, and don't don't forget about the much lower power usage and thermals. ;)

The 28nm gen is certainly shaping up to be an interesting one.

Here's to hoping some better CPUs follow suit sometime soon.

It's a very wide gap between mobile and desktop GPUs, but my i7-2820QM literally is a locked, downclocked 2600k. It's hard to justify rolling a desktop when anything less than said 2600k feels like a lateral move.

Don't make me buy the same chip twice. Release a new CPU or let me extract my notebook CPU, throw it into a desktop, and even out the clock difference.

I find this news piece is written in an odd variation of english. It's not misspelled like Kevin's usual stuff, but it sort of sounds like a google translate or something.

[citation][nom]confish21[/nom]Ok, Ive been waiting to bring this up... Anyone else use google translate to check out expreview.[/citation]
I've stopped using it at all. The other day I wanted to translate a cake from danish to german. The end product according to google was 'green poison kuchen' - so only a third of the words were even german at the end of the day.

Was in the process of picking up a 6850...actually had it ordered but cancelled in the hopes I can hold off and grab a 7850. Everyone agree that it would be worth the wait?

I can't wait to see what Nvidia offers in the future. Can you say Physx ? I want a card with that and so ATI I pass on what you are offering.

I don't think Physx is the selling point it once was. Its a very specific library that was useful when general GPU Compute architectures were unavailable. But now that AMD is jumping in whole hog with GCN to match NVIDIA, I foresee physics based computations moving away from Physx to use general GPU compute libraries. General GPU compute is the best path because it will support the greatest number of cards and therefore the most customers as well.

Its only a matter of time before Physx dies in favor of general GPU computer libraries.

Performance wise 7870 will fall somewhere between 6950-6970 closer to 6950. It will not surpass 6970 at all that is where 6890 will take the place to fill the gap between 1792 and 1408 SPs and to replace 6970
The average performance difference between 7970 and 7950 is about ~15% and 7950 has ~12.5% less SPs...likewise 7870 has 31.2% less SPs than 7970 so one should expect performance somewhere in this range 31-37.5% less...Anyway 6950 has about 31% less SPs than 7970 and performance wise it is on average 35% slower. So let's look at the 6950 and 7870, same number of SPs, ROP'S, and TMUs. So we are looking at performance somewhere between 31-35% less than 7970 or 0-4% better than 6950.
The price you pay for 1SPs for 7850 at $220 is $0.171
The price you pay for 1SPs for 6950 at $250 is $0.177
The price you pay for 1SPs for 6970 at $300 is $0.195
The price you pay for 1SPs for 7870 at $300 is $0.213
The price you pay for 1SPs for 7950 at $450 is $0.257
The price you pay for 1SPs for 7970 at $550 is $0.268
 


Ridiculous comparison. 7000 SPs do a lot more than 6000 series, plus there's other factors like the 7900 having a bigger bus.

Wait till the reviews are out, at least, and then look at price/performance not price/SPs.

Yep, I was about to write a similar comment. That's pretty much what they are doing I'll make it simpler.
