Introducing AMD’s HD 6790

Call Of Duty 4: Modern Warfare
iw3mpcod4

Call of Duty 4: Modern Warfare (CoD4) is a first person shooter running on a custom engine. It has nice graphics but the engine is somewhat dated compared to others and it runs well on modern PCs. It is the first CoD installment to take place in a modern setting instead of in World War II.

It differs from the previous Call of Duty games by having a more film-like plot that uses intermixed story lines from two perspectives; that of a USMC sergeant and a British SAS sergeant. There is also a variety of short missions where players control other characters in flashback sequences to advance the story. Call of Duty 4’s move to modern warfare introduced a variety of modern conventional weapons and technologies including plastic explosives.

There are currently about 20 multiplayer maps in CoD4. It is still very popular. CoD Modern Warfare 2 was also released with updated visuals but it is also not very demanding on graphics cards.

Our timedemo benchmark was created by ABT’s own Senior Editor and lead reviewer, BFG10K. It is very accurate and totally repeatable. Here is CoD4, first at 2560×1600 resolution with all in-game settings completely maxed out plus 4xAA:

Let’s next test at 1920×1200.

We see that a popular multiplayer game is very playable even on midrange graphics cards and it plays very smoothly with this generation’s top video cards. The HD 6790 is faster than the GTX 550 Ti and overclocked it is slightly faster than the GTX 460.  It does an admirable job compared with the HD 5770 that it replaces and it scales nicely with increasing clockspeeds.

    I still think that 6790 is the 5830 of its generation. Too many cuts leads to a crippled chip that exists only because AMD marketing wanted to sell you a chip that would otherwise be thrown in the trash bin because it had too many defects to pass as a 68xx/69xx. That might be good marketing but it’s not a good deal for the buyer.

    Beating the GTX 550 is an accomplishment, sure, but not much of one, since the 550 is such a garbage card to begin with.

    If you’ve got $150 to spend on a video card, just save up and buy a 6950 for $250. That extra $100 has a great deal of marginal value. As opposed to, say the $150 delta between a GTX 570 and 580, which is just like throwing money away.

    This generation of GPUs at 40 nm has been rather underwhelming on the whole. No true spiritual successor to the 8800 GT from either the red or green team. And with DX 11 adoption at a virtual trickle, thanks to the negative effects of consolization, it would appear that progress will be slow until the next-generation of consoles appears.

    Bring on 28 nm.

    On the bright side, another great review by ABT.

    100% agreed with above comment!

    Well, I’d say that GTX 460 1GB is almost like the 8800GT of its time, but only if you could find one for $150 with rebates.

    Both companies are desperately trying to keep the prices up. Now, a $500 GTX 580 is starting to look a bit “mediocre” with some recent games like Metro 2033, Mafia 2, etc.. The price to pay for eye candy on the PC is rather high, and many games are console ports from consoles that are “several” years old, or a few PC generations behind.

    I find it to be really misleading when AMD claims that the 6790 has 256-bit memory when the sawed-off ROPs limit access to only half of the available bandwidth, as the card behaves exactly like as if it has 128-bit bus. For more on this, if you want to discuss on the forums here, I started a thread: http://alienbabeltech.com/abt/viewtopic.php?f=6&t=22733
    I also believe that all Barts GPU’s are VLIW4-based like the rest of Northern Islands. It’s something else that appears to be in a dimly-lit area.. when one shines a candle in that area, something just doesn’t look right.
