Overclocking: Gaming Performance

Since both of our retail cards reached the same overclock, for the purpose of our graphs we’re simply listing the same number for both cards. In turn both cards are listed so that anyone flipping through the graphs without reading the accompanying text can still see both cards.

With our overclocks in hand, the core clock difference between these overclocked cards and the 7950 starts to get ridiculous. At 1200MHz for the 7870s, this is a massive 50% core clock advantage on the 7950; the overclocked 7870s have 50% more frontend and ROP performance compared to AMD’s next card up at stock, furthering the gap caused by this effect.

The end result is that more often than not, the overclocked 7870s can meet or beat the stock 7950. Even the 7970’s lead is uncomfortably narrow at times, such as in Battlefield 3 at 1920. Ultimately if you liked the 7950’s stock performance it’s possible to get something similar for upwards of $80 less if you don’t mind some overclocking, and chance is on your side.

    On the first page, you make an error in the table saying the PCS+ is Triple Slot while the IceQ Turbo is Dual Slot; obviously this is backwards based on the photos.

    How about the biggest error of all... no mention of the near paper launch - we get a pretend scenario that the 7870 and 7850 are somehow populating retail channels... no mention in the entire article of the terrible near non supply.
    Instead we get the reviewers wined and dined at Cebit and or GDC, where they are treated to the "unveiling", then handed special overclocked models, then we all get to pretend you could buy it up as of yesterday...
    Nope, egg had 2, one sold and the buyer commented that made 1 available (7870). Same thing earlier. 7850 wasn't any better.
    So AMD gets a giant pass on their near pure paper launch.
    Is that free weeks long yearly for 500 'reviewers/reporters' AMD posh Island Vacation bribe coming up soon or what - did they just get back from it ?

    What is the use of scheduling? Is it only useful for compute or does it have usefulness in graphics also?

    Here is the link to an interesting overview performance 7870 and 7850 of 5 Web sites competing Nvidia cards - GTX580 and GTX570 and penalties of the previous generation AMD - 6970 and 6950.

    Analysis of the results of the Radeon 7870 and 7850 in 12 games and 5 resolutions:

    You will know the relationship between average interest rates these cards and you will find out in which graphics card is better in the game and resolution.

    You've put tripple width and 390$ for PCS, while you say otherwise in article. Tripple width and 390$ is mentioned in part about HIS card, so I believe you've mixed up the columns.. or at least part of data, as memory OC seems to be correct for both cards in table. Please review and correct as not to confuse readers..

    I see this 7870 is virtually the same as the GTX 570, and when I check the prices a GTX570 is $260-$289 and the 7870 is $369 minimum.
    This card at it's current price is no value at all.

    For comparison sake you should throw a $309 GTX 570 Classified in there. (which will beat it) But OC to OC is only fair.

    If 7870 is overpriced, then what is GTX 580?
  • Zebo - Tuesday, March 20, 2012 - link

    Cheaper than these cards and faster!

    On the 4th page:
    Numerous times before we’ve seen loud & cool cards, but it’s rare to come across a loud and quiet card.

    You should give the article to other editors before you publish it. Happens to myself all the time.
