Core i7 965 Extreme Versus Athlon X2 7850
A Platform That Makes Sense
You’ll notice that we just ran that full suite of gaming tests on an Intel Core i7 965 Extreme-based machine, complete with X58 motherboard, 6 GB of pricey DDR3 RAM, and a 1,100W power supply—all to test a $109 graphics card.
We do this for a reason. When you test a platform that’s clearly overkill, you help minimize the number of potential bottlenecks that could inadvertently affect results. In a graphics card comparison, you want to reflect only the performance differences attributable to the card in question. But without a doubt, the configuration itself is unrealistic. So, we took what we hoped would be a sweet-spot setting, 1680x1050 without AA or AF enabled, and pit the powerful Core i7 965 Extreme against a significantly less-muscular processor being launched today, wondering if we’d see any performance variation.
The Athlon X2 7850 is a 65nm, 2.8 GHz chip based on the Kuma design. It sports two cores, twin 512 KB L2 caches, and a shared 2 MB L3 cache. With an expected price tag around $70, it’s a reasonable complement to the $109 graphics card. Ironically, you’d likely spend the most money on a motherboard in this little setup.
It’s generally thought that a majority of games are not optimized to take advantage of threading, but there is more than just a core discrepancy in play here. Clock speed, cache, micro-architecture are all different. But if these titles were purely graphics limited, none of that would matter and you’d still see similar performance numbers across the board.
A couple of apps are in fact decidedly limited by the muscle of our little Radeon HD 4770 here. Stalker and Crysis—two obvious contenders for such an honor—achieve low 30-ish frames per second on the $70 and $1,000 CPUs. The rest of the field does demonstrate bias toward the Core i7 965, though, subtly suggesting that we should probably recommend a quicker CPU for gamers. The Phenom II X3 720 does cost twice as much, but would likely make a prudent upgrade. Far Cry 2, Left 4 Dead, World in Conflict, and Grand Theft Auto 4 all stand to benefit from a quicker CPU.
Couldn't say it better, myself.
Looks to be a pretty good card, but nothing spectacular. 40nm is nice, a little cheaper HD 4850 (fewer FPS, too), but all in all, nicely done.
I wonder who'll sell more, now, the 4850 or the 4770?
ATI is leading us into graphics nirvana.
great card for 16x10 resolution. good job ati, you've done more damage to nvidia in the past year than they've done to you in the pass 3-4
just checked newegg and they all have aftermarket coolers on them... wow *_*
Nah, they're reference coolers from AMD. From what I heard, AMD gave the AIB partners a choice between the dual slot and the, for lack of a better term, uglier cooler. Apparently the "uglier" one is cheaper so that's what you're probably going see for now.
