should be (if math doesn't fail me)
still great review, as always.
Excellent overcloking, way to go ASUS!
W1z, just a sugestion, why not put o/c results among the others? (all the benchmarks and de summaries)
That would be awesome!
PD: wake me up when this card costs $240 =)
Good suggestion, but I suspect because overclocking is like gas mileage - it may vary from one car(d) to another.
It was finally smart of asus not to bump price up on such a miniscuile overclock.
Id only pay higher if the cooler is far better as of keeping stock temps down while keeping noise tolerable. Also if the pcb is ref price shouldnt change drastically
makes graphs more complicated to read: "more colored bars", and adds a ton of testing time, running all the benchmarks again with oc
Wtf is wrong with the power consumption on this card? it only has 10% oc and no overvolting.
But W1z, that way we can compare o/c 7870 with the other cards on all the games!, please!!
The sample overclock resulted in +14.1% performance.
Get a calculator, turn it on, multiply results of benchmarks by 1.141.
Why should he waste his time rerunning benchmarks? He'd have to redo ALL benchmarks for ALL cards...
thats what the similar reviews button is for, review the product yourself
14.1 x everygame? it AVG, not the same increase for every game ...¬¬
amazing card must say
Looks like a nice card, but I probably wouldn't get rid of my 6950 unlocked for it due to the seemingly small performance difference. Probably decent if you don't have a 6950 and can't afford the awesome GTX 680 that beats nearly everything but costs $150 more.
It's a percentage. If the overclock gives that percentage in one benchmark, it will give it in all other benchmarks. If you want to look at it another way, think of it as a 'modifier', apply the the 1.141 modifier to the Asus Direct CUII at stock and you get the performance in any particular benchmark based on the percentage modifier. It has absolutely nothing to do with any manufacturer/designer specific features of the gpu, or any specific code in a game benchmark, it's an increase in overall hardware performance. It applies to all benchmarks...
Why do I even bother?
There are games that don't go up the same way others do, some get huge increases some don't, is that so hard to understand?
Anyway, thanks for your OPINION, i don't have to agree with you
"games that don't go up the same way others do..."
It doesn't apply well to cpu limited games, like Starcraft 2, but it applies to every other game out there. It doesn't matter what game it is, who coded it, what the gpu is; if you increase the performance of the gpu, it increases the performance in all games and benchmarks by the same percentage, except, as mentioned, in cpu limited games.
I can tell that your English is not precise enough for you to articulate yourself properly, and that you probably have not understood everything. So I'll leave it there.
Here's to hoping you don't make another intemperate comment based on misunderstanding.
Good, SLI scales better
I am sure something is wrong with the 7950/7970 because even with about 40% higher sp and 60% more transistors at 1920*1200 HD 7950 is only about 6% and HD 7970 is 18% faster than 7870. 7900 also has a 384 bit wide memory. :shadedshu
I agree something is off or they are just clocked too low stock
7870 and 7970 both @ 1ghz there will be only 15-20% difference but 7970 has 40% higher sp and 60% more transistor and also 384 bit wide memory. sometimes 7950 gets beaten by the 7870.
Might as well save some $ and just get this over the 7950.
WOW, 984bit that's monstruous!!
Maybe the 7970 & 7950 are bottlenecked?
It's the same thing in all reviews. The only potential bottleneck is ROP's, but I find that unlikely. There has to be something at work in the 79xx cards that makes them so much less efficient than Pitcairn...
Sorry its 384 bit not 984 bit. You should understand that its only a typing mistake.
7970 isn't bottleneck-ed by Rops because there is no game out there which can use 70% rops of the 7970
