XFX 8800 GTS 512 and Asus 8800 GT 512 - G92 shoot out

Overclocking

Overclocking
 
Overclocking was performed using Nvidia's drivers and the nTune plugin. No hard or soft mods were performed on the cards and overclocking in this way is meant to represent an "easy overclock", giving value for money on each card without making too much effort.
 
Results
 
Here's what happened:
 
overclock
 
Oddly enough, the cards were almost the opposite of each other. Whilst the XFX 8800 GTS 512 XXX Alpha Dog Edition made some great ground up on stock core clock, the Asus 8800 GT Top had a nice memory overclock.
 
Let's see how this affects performance:
 
3dmark06 overclocked
 
The chart above shows us that the large core overclock on the 8800 GTS was more effective than the large memory overclock on the 8800 GT.
 
Still, what we have to remember is that both of these GPU's are overclocked out of the box and so any overclocking above that is even more of a bonus than normal.
 
Power consumption
 
For a good approximation of the power consumption of each card, I measured the power consumption of the total system for each card at the wall socket.
 
Idle measurements were taken over a 30 minute period sitting on the desktop of Windows Vista and load measurements were taken again over a 30 minute period whilst stressing each card using RTHDRIBL in full screen mode 1920 x 1200.
 
power consumption
 
As you can see, the power consumption of the XFX 8800 GTS and the Asus 8800 GT was very similar at idle, but at load the 8800 GTS pushed up towards 8800 GTX numbers. Still, the beastly 8800 GTX managed to stay a fair way ahead in the energy guzzling stakes.

Great insight into the higher end of the gpu spectrum.

I have to be fair, even tho u`ve got a 1 to 4 positioning, I don`t think there`s that much in it for any of them. I know the Ati slides in the rankings, but it does show itself to be a fine card.

An interesting comparison would have been performance versus costing, seeing as they`re as close as they appear to be.

I`m a bit at odds with the oc results too. I simply can`t achieve the memory overclock on my GT without it having fits. But I can clock the gpu to around 720 (from 670).

What would impress me is some1 buying the cheapest GT, putting it under water, and claiming back those clock hertz with their superior cooling. Sounds nice.

Suprizes me a bit tho that the GTS isn`t launched as a bigger performer. Although pricewize, it does seem to start from stock where the GT limit starts. Leaving u further to climb

Nice review m8, think every1s doing the "going to bed early to get up early" trick Quote

Nice to see this review is finally up

Shame I cant view it as 128k is painfully slow :sleep:Quote

Thing is though there is a BIOS voltmod for the 8800GT that GREATLY increases its overclockability. If there isn't one for the 8800GTS I see them both reaching high limits but so far the 8800GT seems to OC better. With good cooling and the volt mod this thing easily passes 800mhz core, I've seen some at 850+.

What you also go to look at as well is shaders, they seem to be the key thing atm if the shaders OC much better on the 8800GT, which I guess they kinda should since they could simply lock the worst performing ones to get it top out better, it could impact performance in certain titles a lot.

Nice review though I was surprised the 8800GT didn't clock more, there wasn't a heat issue was there?

It should also be said about the supposed problems of the memory modules on the 8800GT, seems that long term use of the memory at 2ghz+ and it brakes. Thats why some companies like Zotac use better memory modules for their cards.Quote

Great review Kempez, can't wait to open my GTS tomorrow Quote

The GT was a little hot yes, but I will never change the cooling or take off the heatsink prior to running any tests. I test every card as it would be when it appears on your doorstep

Volt-modding is not part of the overclocking testing as the percentage of users who do that is small and it voids any warranty you have.

An overclock is dependent on what RAM is used, what cooling is like and also what luck you get with the silicon...the overclocking gods didn't smile on me this time

@Rast: I agree, the ATI card is a great card as I said in the ATI review, but this review was for these two cards. Having said that: would I buy the HD3850 personally? No, I'd go for an 8800 GTS 512mb G92 or an 8800 GT 512 G92 It's simply not fast enough with every game, I'm afraid.Quote
