University of Antwerp stuffs 13 GPUs into FASTRA II supercomputer
The researchers at the University of Antwerp's Vision Lab caused quite a stir last year when they built a supercomputer with four high-end NVIDIA graphics cards, but it looks like they've truly stepped up their game for their followup: a supercomputer that packs no less than thirteen GPUs. That, as you might have guessed, presented a few new challenges, but after wrangling some flexible PCI cables into a specially-made case and loading up a custom BIOS courtesy of ASUS, they were apparently able to get six dual-GPU NVIDIA GTX295 cards and one single-GPU GTX275 card up and running with only a few hiccups. As before, the big advantage with this approach is that you get an enormous amount of computing power for a relatively small cost -- twelve teraflops for less than €6,000, to be specific. Head on past the break for a pair of videos showing the thing off, and hit up the link below for the complete details (including some jaw dropping benchmarks).
EVGA GeForce GTX 275 co-opts a GTS 250 for PhysX duties
Ready for some more dual-GPU madness, only this time in the resplendent green of NVIDIA? EVGA has gone and concocted a special Halloween edition of the GTX 275, which has sprouted an entire GTS 250 appendage solely for PhysX gruntwork. Dubbed a new form of Hybrid SLI, EVGA's latest combines -- for the first time, from what we can tell -- two different GPUs and assigns them with specific and mutually exclusive tasks. Whether this concept takes off will depend to a large extent on the effectiveness of PhysX acceleration and whether it can show more efficient scaling than regular old SLI with two boards or more conventional dual-GPU setups like the GTX 295. Color us intrigued, either way. P.S. - That's what the actual card will look like, we're not making it up.%Gallery-77092%
NVIDIA GTX 275 / ATI Radeon HD 4890 review roundup
Unless you've started your weekend early, you have probably realized that both NVIDIA and AMD announced new GPUs this morning. Coincidental timing aside, it sure makes things easy for the consumer to eye the respective benchmarks and plan out their next mid-range GPU purchase accordingly. A whole bevy of reviews, tests, graphs and bar charts have hit the web this morning extolling and panning the pros and cons, but without getting too deep in the nitty-gritty, we can sum things up pretty easily with this. NVIDIA's GTX 275 showed performance that placed it perfectly between the GTX 285 and GTX 260, and in all but a few off-the-wall tests, it outpaced the ATI Radeon HD 4890 (albeit slightly). Granted, the HD 4890 was called the "fastest, single-GPU powered graphics card AMD has ever produced" by HotHardware, though apparently even that wasn't enough to help it snag the gold across the board. If you're hungry for more (and you are, trust us), take the rest of the day off and dig in below.Read - HotHardware GeForce GTX 275 reviewRead - HotHardware Radeon HD 4890 reviewRead - ExtremeTech GeForce GTX 275 and Radeon HD 4890 reviewRead - DailyTech GeForce GTX 275 and Radeon HD 4890 reviewRead - X-bit Labs ATI Radeon HD 4890 reviewRead - ComputerShopper ATI Radeon HD 4890 reviewRead - Guru 3D GeForce GTX 275 reviewRead - Guru 3D ATI Radeon HD 4890 reviewRead - PCPerspective ATI Radeon HD 4890 review
