NVIDIA GeForce GTX Titan leaks, could cost a grand
NVIDIA's GeForce GTX 690 currently wears the world's-fastest-graphics crown, unless you count the limited edition Ares II, by cramming two Kepler GPUs onto one mainstream board. When it comes to improving on that, some leaked European retailer listings suggest NVIDIA might not wait on a completely next-gen architecture, but may instead try to deliver similar performance through a less power-hungry single GPU design. The listings, gathered together by TechPowerUp and VideoCardz, point towards a pricey new flagship, the GeForce GTX Titan, that would be a graphics-focused adaptation of the beefy Tesla K20 computing card. It'd pack 2,688 shader units, a 384-bit memory bus and 6GB of RAM, all with one chip -- for reference, the GTX 690 needs two GPUs to offer 3,072 shader units and has 4GB of RAM. There's no confirmed unveiling date, and the primary leak on a Danish site has actually been pulled, but ASUS and EVGA are rumored to be launching their own GTX Titan variants as soon as next week, possibly in the $1,000 to $1,200 ball park. That's a short wait for what could deliver a serious boost to game performance, not to mention bragging rights.
Cray's Jaguar supercomputer upgraded with NVIDIA Tesla GPUs, renamed Titan
Cray's Jaguar (or XK7) supercomputer at Oak Ridge National Laboratory has been loaded up with the first shipping NVIDIA Tesla K20 GPUs and renamed Titan. Loaded with 18,688 of the Kepler-based K20s, Titan's peak performance is more than 20 petaflops. Sure, the machine has an equal number of 16-core AMD Opteron 6274 processors as it does GPUs, but the Tesla hardware packs 90 percent of the entire processing punch. Titan is roughly ten times faster and five times more energy efficient than it was before the name change, yet it fits into the same 200 cabinets as its predecessor. Now that it's complete, the rig will analyze data and create simulations for scientific projects ranging from topics including climate change to nuclear energy. The hardware behind Titan isn't meant to power your gaming sessions, but the NVIDIA says lessons learned from supercomputer GPU development trickle back down to consumer-grade cards. For the full lowdown on the beefed-up supercomputer, hit the jump for a pair of press releases.
Pentax douses K-m in olive, K20D in titanium
We know, you're a firm believer that there's evidence of thaumaturgy splattered all over here, but believe it or not, all it takes to create a camera in a new color is powerful signature and a little paint. As Pentax has done so often in the past, it's pumping out new editions of old cameras with fresh hues. The latest duo to don new Springtime wardrobes is the K20D -- which is now outfitted in titanium -- and the K-m, which now sports an absolutely peculiar olive shade. Both models are being limited to 1,000 in quantity, and while no price is mentioned, we get the feeling a ticket to Tokyo may be your only shot at acquiring one.Read - Olive K-m, via PhotographyBLOGRead - Titanium K20D, via PhotographyBLOG
