    If AMD weren't a little worried they wouldn't have paper launched and gotten everything out as quickly as humanly possible. Nvidia seems confident GK104 will be enough to counter AMD offerings, only time will tell.

    a paper launch is better than a wood shop launch ;)

    Why? It performs the same as the 7850, just consumes more power.
    If it's unlocked to 6970 it outperforms the 7850 with 5%.

    How does the ASUS GeForce GTX 560 Ti DCII TOP 1GB card compares to the Radeon HD 7850 card?

    I see the overall improvements in performance is 9% better for the 7850 card over the stock GTX 560 Ti card.

    But the ASUS GeForce GTX 560 Ti DCII TOP card is a bit more powerfull than the stock GTX 560 Ti card.

    If the Radeon 7850 card is just 2-3% better than the ASUS GeForce GTX 560 Ti DCII TOP card, then i don't see a reason to change out my GPU to the Radeon 7850, because the GTX 560 Ti cards have CUDA and PhysX that i actually use in some programs and games that would make rendering things in Adobe Premiere Pro CS5 to take much lesser time to render for example.

    Just wanted to give a big THANK YOU out to W1zz for the review (and all past ones, too) - TPU's graphics reviews are - for me - the best there are, as everything that needs to be tested gets tested and compared to all other relevant cards.

    Maybe rops its the bottleneck seeing they both have 32.

    Still, the ratio between SPs and performance is really weird comparing HD7800 to HD7900

    I think we would see a bigger difference between both as we went to lower resolutions in that case, and I always say that if you are making a GPU you just don't let a very small portion of your GPU bottleneck the rest, meaning they would have put 40-48 ROPs in that case, since they are completely decoupled now and die size wouldn't increase a lot. But who knows it could be.

    But if I had to bet I'd say it's the same "problem" as with previous generations HD6000 and HD5000 and the culprit is the front end. With this one it would be the 3rd generation to suffer from this small-ish limitation, but it's their decision, a compromise that probably allows them to make it simpler and release cards easier/sooner and with less problems and R&D. It's worked for them in the past so why not.

    I'm very happy with my 2x 6950s for the time being, but these are some nice cards.

    A bit pricey, but nice nontheless.

    Nice review.

    I hope the price will drop. If so, maybe the HD7870 would be a nice replacement for my HD6950. It depends if I can get at low price a second HD6950. Planning to play on eyefinity 3 monitor, so :)

    disappointed with only 1 crossfire tab :(
    AMD WHY U LIMIT ALL LOWER CARDS TO TWO CARD CROSSFIRE NOW!
    price is right where I thought it would be.

    Unless GTA5 is a killer I think one massively overclocked 7870 is in my future.

    Yeah...5xx series was already overpriced too, at least at this later stage in it's life.

    Can't wait for the Crossfire reviews.

    Very good show... AMD and W!zzard, while not extra ordinary for a reference board… I'm liking! :toast:

    Consider that very quickly most AIB's will offer OC'd and different coolers at or not much more than such MSRP, so start pricing isn't the worst. 78XX OC's are stratospheric, and if 7770 Cross-Fire is any indication 7850’s CF and some OC will be very quickly be the legitimacy for low power and $/perf.

    We've yet to see how Nvidia will present their TSMC 28Nm price increase for the coming GK104. I think we will see Nvidia GK104 in 3 variants; first something that works above a 7850 for under $300, then the more common OC’d cards can really sparing with 7870 $370; lastly a limited run of Uber and FTW OC’s that can best the 7950 at 1920x, but power would be stratospheric and $420 or above.

    Well according to Charlie next week we'll know more about Kepler as the press will be briefed about the GTX680. If GK104 is the new GTX680 then be very sure that it will be better than Tahiti XP. Prices will be probably according to performance and market.

    Umm, good for you.
    So a single review that disagrees with one from W1zz

    http://www.techpowerup.com/reviews/AMD/HD_7850_HD_7870/26.html


    When his review and others show different, and then the overclock results come in where they have....talk is cheap.

    Well based on that what will Nvidia "call" their top dog once GK110 is brought to market?

    I don't care what chip they use or what they call it, if it battles performance directly with Tahiti(s) and priced in the same realm $400-500 it's the successor to the GTX570/580... and Nvidia needs to think up a new name for the top dog whenever it shows!

    If Nvidia feels there a whole new rung on the enthusiast realm and they can bring it to market at $600+ best of wishes... Selling them and really bringing anything to their bottom line or if they want to wear a crown at that price... it's fine.

    You're forgetting the rest of the results (other cards) are benched on the same system as well.
    Consistency is sorta important in reviews, at least the ones that are worth reading.

    Nice review wizz. :rockout:
    7870 seems like an awesome card, just a little bit pricier than I suspected.

    +59765723894568234756 for consistency in reviews.

    Its a tough call when to switch platforms, thats for sure. If you do, then all other cards/reviews, especially at lower resolutions, their results are rendered useless to compare.

    Nice review on these cards W1zz!

    this sure is incredible, and only makes me think an hd7970 is disappointing
    an hd7870 has 1280 stream processors(40% less than hd7970), and yet performs only 20% slower than an hd7970
    i guess hd7970 can use some more memory bandwidth thats for sure because as far as my calculations(hd7970 vs hd6970) went GCN cores were on par with VLIW4 cores in graphical operations, and had double the performance in compute
    but with hd7870 out this changes everything, its almost as if the GCN cores on the pitcairn are doing a better job than tahiti
