Asus GeForce 8800 GT – first look
Almost as fast as the GeForce 8800 GTX, but for much less money
With Christmas approaching, manufacturers are frantically churning out their merchandise. Shiny new products range from silly, stocking-filler fripperies to huge items that won’t even fit under the tree. The new GeForce 8800 GT graphics card slots in between these two extremes - it’s a long graphics card (9in, in fact) with a single-slot cooler on top. It’s the card that Nvidia hopes you’ll buy this Christmas, but why?
This is the first PCI-E 2.0 card we’ve seen, so obviously, it’s almost twice as good as those rubbish old PCI-E 1.1 cards, right? As ever, though, matters aren’t that straightforward. All PCI-E 2.0 offers over PCI-E 1.1 is twice the usual bandwidth (if the chipset supports PCI-E 2.0, which currently only applies to the super-expensive Intel X38) and some extra power through the slot. Determining whether the extra bandwidth makes a difference to gaming performance is nearly impossible, as you can’t switch between PCI-E 1.1 and PCI-E 2.0 on an X38 motherboard. This means that we’d have to test on different motherboards, which would invalidate any comparative results. At least PCI-E 2.0 is backwards compatible with PCI-E 1.1, so this card will work in any motherboard with a 16x PCI-E slot.
First, we tested to ascertain whether an X38 board could power the card through just the slot, thus avoiding the need for a separate PCI-E power cable. Unfortunately, though, the card wailed like a distressed pre-pubescent on helium until we plugged in the 6-pin PCI-E connector. With a PCI-E 2.0 slot providing 150W of power (double that of a PCI-E 1.1 slot), the GeForce 8800 GT resides in the high-energy bracket of GPUs. However, our test system only drew 240W from the socket during gaming, making the GeForce 8800 GT 6W less energy-hungry than a 320MB GeForce 8800 GTS.
Nvidia has stated that the board will draw no more than 105W, and also claims that the chip will be more power efficient compared to its predecessors when idle. This frugality of power consumption is good considering the specs of the new GPU, codenamed G92. There are 112 stream processors running at 1.5GHz, while the rest of the GPU runs at a respectable 600MHz. That means that the core of the 8800 GT runs faster than that of the 8800 GTX (575MHz), while the stream processors are clocked at the same speeds as those on the 8800 Ultra.
A little maths shows just how impressive this new GPU is. Take the amount of stream processors and multiply it by the speed at which they operate, and you have the number of peak stream processor operations per second. As it’s the stream processors that are rendering the eye candy, this figure is fairly indicative of performance even if it's only a very rough guide. The 112 stream processors in the 8800 GT run at 1.5GHz, so this GPU has a peak of 168 billion stream processor operations per second. Comparatively, the 8800 GTS (either version) has only 96 stream processors running at 1.2GHz, providing ‘only’ 115.2 billion stream processor operations per second.

i think that it is more like ford releasing the new Mondeo at the price of a mondeo, as opposed to the price of a ferrari. Don't forget, 450 pounds is a lot for a graphics card, that'd be the ferrari price.

...Ferrari were to announce the arrival of a new lighter, faster, more powerful, more aerodynamic, more comfortable F430 for the price of a Mondeo, and that just about sums this up. I don\'t care what anyone else thinks, this, for whole £76 cheaper than my 640Mb 8800GTS (the cheapest XFX model) is the January sales come early. I\'m not going to send the card back (unless it screws up like my last one) but I will be buying one of these in the new year for my 3rd workstation and I\'d advise anyone thinking of getting any other card to do so as well because the power:price ratio is too good to ignore. My only reservation, now that normal memory amounts are back in fashon after the wierd 320/640/768 varieties, is... are they going to release a 1Gb version...?

Actually I think I\'m good with my 8800GTd 640MB. I bought to be able to play at 1920*1200 and as test from various websites show at that resolution (especially) with AA and/or AF enables the 640MB tops the GT. Given the fact that I have overclocked mine to above ULTRA (648-1620-2106) numbers, I feel no need to buy a GT. But I am faced with 2 options: eithere sell my GTS or buy another one and pair them for some HD FPS gaming. @ Landy_Ed How much for yours (and does it OC?) or how much would you willing to pay for mine? :-)

I have a 8800GTS 640MB and the only keeping me sane is the fact that I managed to get a stable OC to 648-1620-2106, which I think puts me on par, at least, with the 8800GT, but more suitable for higher resolutions (1920*1200 and above) due to the extra ram. (still, anyone interested in bying it?)

The only problem in this industry (and hobby) is that as soon as you buy it, its out of date, no matter what it is. More so is it in the past year, where Intel and Nvidia have totally ''Blitzkrieged'' the market with its massive range of products, more of which are coming out every month. Im dissapointed that 2 months back i bought a 320mb gts, only to find a cheaper and more powerful, single slot card to come out and put the big V sign in my face ! But besides the point Build a system, upgrade it, throw it out, build a system, upgrade it, throw it out, you know the drill..... Go Buy This Card! Alternatively, buy my 320mb GTS for only £130 ? xD

Good first look. Pleased to see the benchmarks at 1680x1050 as that's the res I tend to run at and it's frequently overlooked in most 4:3 aspect centric reviews. I'd be interested in details on a couple of things though: - What is performance like under the Source Engine, UT3 and Crysis? Games like FEAR, STALKER, etc. aren't really stressing modern GPUs imo. - What aftermarket coolers fit with the 8800GT? The current single-slot cooler hits 91C under load. That's not good, and will certainly limit the long-term overclocking potential of the card. There's stuff all detail out there about which aftermarket VGA coolers will fit. I've seen some reports that the mounting holes are the same as the 7xxx series cards but little corroboration. Any info would be useful. ;o)

i got it from ebuyer, it was £154.99! THEN i used google check out! so a tenner off! i was wondering if anyone and any dimensions for this card at all?
Comment by jonconlon at 11:04am 30th October 2007
If you're an early adopter you would, like me, have had an 8800GTS 640mb for a year already and probably be looking to upgrade anyway. If having great gaming performance and being able to play Crysis in DX10 mode on high detail at 1680x1050 is being a sucker, then so be it! If you've only just bought your 8800GTS then yes, you would be slightly miffed. I could flog my 8800GTS and grab a pair of these, or just wait until they refresh the 8800GTX with a 65nm chip and get one of those. Choices choices!

Does having a PCI-E 2.0 slot really make any real world performance difference with this card?
Comment by AlphaLife at 3:23am 30th October 2007
Not like I was first off the bat, I waited awhile. If I'd bought a GTX I'd be really annoyed. This is the equivalent of buying, say, the new ford mondeo, then 6 months later the new fiesta comes out at half the price & outperforms the mondeo to boot. Normally it's the same thing that gets dropped in price a fair whack & the new higher performance stuff comes out at similar price points. Consider the PS, always it comes out at a high price then drops over time. Same with most goods, and usually computer kit as well. This is not about early-adopting per se, as it is the early adopters that normally cover R&D costs before economies of scale come into play at the low-mid price market. Instead, I think nvidia are trying to deliver a killer blow to ATI before they've managed to respond properly to even the original card. I also think they've missed a trick, because another £30 on the rrp would have made all the difference while still not hurting their sales but left less of a poor taste in the mouths of those who spent that little bit more. Look at the prices, it STILL costs a lot more for the GTS 640 despite the new GT pricing & performance. So there's a lot of product lying around that will have to be sold at a loss. Lke I said, I'm glad about the card, if for no other reason that the current draw of gpus is getting stupid & needs to go the other way, but why alienate the very people who cover the initial costs - not much of a reward & that's how you lose loyalty.

"Early adopters" is just a nice way of saying "Suckers." In an industry where everything gets cheaper, faster, cooler and more quiet with time, it just doesn't make sense to buy early.
Comment by MetaCatastrophe at 5:07pm 29th October 2007
that tiny fan must work it's socks off... are there going to be any aftermarket dual-slot coolers!? or any single slot but larger-fan models around the corner?? otherwise i'm sold...

The early bird may get the worm Landy_Ed, but the second mouse gets the cheese!

overclockers just got a whole range of them in, here: \

Sounds good but does it support direct X 10.1 and how does it run at 2560 x 1600
Comment by stephen at 1:22pm 29th October 2007
Pleased that the card is here, but it fairly insults the early adopters - normally better kit comes in at the same price point, not half the price. Anyone now want to buy an 8800GTS 640? No? (quel surpris)
