GeForce… GTX… 280… so many reviews theses last two days. Where is ATI? Hope with the launch of Radeon HD 4870 we’ll assist to the revenge of Radeon reviews! Anyway, here is a 14-page review by Guru3D about the SLI of GTX 280 in Two and Tri Way.
Guru3D’s test system contains a Core 2 Duo X6800 Extreme Processor, the nForce 680i mainboard, a passive water-cooling solution on the CPU, DVD-rom and a WD Raptor drive. The results:
* PC in Idle = 197 Watt
* PC 100% usage (wattage gaming Peak) = 530 Watt (SLI)
* PC 100% usage (wattage gaming Peak) = 749 Watt (3-way SLI)
Alright, the conclusion really doesn’t need to be very long. Money wise high-end SLI and 3-way SLI doesn’t make much sense, and it never will. It’s bragging rights, and only for very few of you with a 30″ monitor actually a wish. See, the GeForce GTX 280 by itself already is a power house.
Because the fact remains that when you factor the money out, the SLI setup as tested today is just an awful frickin lot of fun. I mean playing Call of Duty 4 at 2560×1600 with 4xAA and every possible image quality setting set to the highest possible setting returns an average framerate of nearing 80 with SLI; that will make you laugh a little giggly. Once firing 3-way SLI and to play the game at the same setting at near 110 FPS .. you’ll giggle again, yet in a weird girlish gay kind of way, it surely is fun folks. No doubt about it.
Researchers at the University of Antwerp in Belgium have created a new supercomputer with standard gaming hardware. The system uses four NVIDIA GeForce 9800 GX2 graphics cards, it costs less than 4000EUR to build and thanks to NVIDIA’s CUDA technology it delivers roughly the same performance as a supercomputer cluster consisting of hundreds of PCs!
The guys explain the eight NVIDIA GPUs deliver the same performance as more than 300 Intel Core 2 Duo 2.4GHz processors.
Another interesting note is that this system doesn’t need SLI, their application uses the NVIDIA CUDA programming model which makes all eight GPUs work in parallel.
Scaling from one GPU to two doesn’t necessarily result in doubling the performance as we’ve seen in countless SLI and Crossfire articles. But what happens when you add a third GPU to the mix? That is what we’re going to find out today by putting three 9800GTX SLI cards together.
So at the moment, Triple SLI might only be worth for people with displays capable of extremely high resolutions- we’re talking 30″ LCDs here. For everyone else including a high-end gamer that plays at 1920×1200 with 4X AA, your standard dual card SLI is more than capable and the scaling of Triple SLI is not required.
