It’s taken NVIDIA a mighty long time to squeeze its Kepler GPU into something more affordable than the GTX 670, but it’s finally happened — the mid-range GTX 660 Ti is out and available to purchase for $299 on boards from EVGA, Gigabyte, ASUS and the usual suspects. Some buyers may complain that’s $50 more than the 560 Ti, while others will no doubt be reeling off their CVV codes already. For its part, NVIDIA claims the 660 Ti is the “best card per watt ever made” and that it beats even AMD’s higher-priced Radeon HD 7950 at 1920 x 1080. Check out the slide deck below for official stats, as well as for examples of what the card can do with its support for DirectX 11 tessellation, PhysX (particularly on Borderlands 2, which you may well find bundled free) and NVIDIA’s TXAA anti-aliasing.
We’ll wait for independent benchmarks in our review round-up before making any judgment, but in the meantime it’s fair to say that this 150-watt card comes fully featured. For a start, it has just as many 28nm CUDA cores as the GTX 670, the same base and GPU Boost clock speeds, the same 2GB of GDDR5 and indeed the same connectivity. The only sacrifice is memory bandwidth: all that computational performance is limited by a 192-bit memory bus, compared to the 256-bit width of the 670. Judging from those specs, we’d expect it to be almost 670-like in performance, and that’s going to be pretty impressive.
We know you’re going to be shocked — shocked! — to hear this, but NVIDIA’s gone and refreshed its high-end line of GeForce GTX cards. The GTX 580M takes the place of the GTX 485M, and NVIDIA’s bragging that it’s the “fastest notebook GPU ever,” capable, we’re told, of besting the Radeon HD 6970M’s tesselation performance by a factor of six. The new GTX 570M, meanwhile, promises a 20 percent speed boost over the last-generation 470M. Both 40-nanometer cards support DirectX11, OpenCL, PhysX, CUDA, 3D Vision, Verde drivers, Optimus, SLI, and 3DTV Play. As for battery life, NVIDIA’s saying that when coupled with its Optimus graphics switching technology, the 580M can last through five hours of Facebook, but last we checked, that’s not why y’all are shelling out thousands for beastly gaming rigs. You can find the 580M in the Alienware M17X and M18X (pictured) starting today, though you might have to wait a week or so for them to ship. Meanwhile, the 570M is shipping in the MSI GT780R as you read this, and you’ll also find the 580M in a pair of 3D-capable Clevo laptops: the P170HM3 and the SLI-equipped P270WN. Handy chart full ‘o technical details after the break.
