Benchmark Results: Left 4 Dead, H.A.W.X, Grand Theft Auto 4

The Core i7s establish a measurable advantage, though it’s hardly relevant since, even at 1920x1200, all of our contenders hover around the 100 frame per second range.

You’d think that applying anti-aliasing and anisotropic filtering would have a profound effect on performance, but in Left 4 Dead, the penalty is minimal. More interesting is the fact that, at both resolutions, our entire field of contenders is exactly even, indicating a graphics bottleneck here.

All of the Core i7s score roughly the same in H.A.W.X., while the Phenom II and Core 2 Extreme processors take a small (yet measurable) lead.

That lead persists at 1680x1050, but is less significant at 1920x1200, even with anti-aliasing turned on to tax the GeForce GTX 260 Core 216 graphics card in our reference build.

This one is known to be more reactive to processor performance, yet most of the field seems fairly even at both resolutions. We don’t test with anti-aliasing turned on in Grand Theft Auto because, simply, the developer doesn’t support it.

    I've never seen anyone saying that the Phenom II is faster than any Core i7...

    Doesn't make any difference with games

    The i7's disadvantage in Far Cry 2 is well-known. That it gets beat in HAWX is something we only discovered this time around. In everything else, it's the faster CPU.

    Are we going to see a price reduction in the 940 or the 965 that gives me any reason to purchase them over the 920?

    Not enough to warrant spending an extra $200 or more, in my opinion.

    Good thing I didn't shell out for the 965 yesterday.

    Oh wait, I don't have unlimited cash, so I won't be shelling out for the 975 any time soon either . . .

    Those game results look like you ran into serious GPU limits. As a result I think you may have been showing a difference in motherboards rather than processors on some of those tests. That does make it an interesting result in other ways though. It looks like the i7 boards have room to mature a little bit more relative to the older tech.

    Who said that AMD holds the crown in performance? I think any half witted enthusiast who hasn't been hiding underneath a rock for the past year knows that the i7 (and even the core 2 duo in some test) is king. I would hope that people who visit tomshardware or rather any tech website knows that in terms of highend power, AMD doesn't come close to Intel at all.

    Likely, yes. If you look back to this doozy of a benchmark-fest, you'll see it isn't under you add a second or third GTX 280 that i7 starts putting on some distance. Up until then, though, it's worth noting that the other two platforms (Core 2 and Phenom) are actually faster!

    Really, any of the i7 processors besides the 920 seems like a waste because of the marginal performance increases for exponential price hikes. I was especially alarmed by the DDR3 memory results. There is the synthetic benchmark advantage of higher bandwidth at higher speeds but absolutely no difference across the board ranging from 1066 to 2133 in real world encoding or what not.

    Pretty absurd, I think I'd just stick with the 920 @ 3.8GHz and some affordable DDR3 1600MHz memory.
