Nvidia Geforce GTX 660 and 650 expected in September, GTX 660 Ti reviewed early
Last we heard, Nvidia was getting ready to expand its its Kepler-based GPU lineup beyond the current high end offerings, with a sub-$300 GeForce GTX 660 Ti arriving at some point in mid-August. Now fresh rumours are pointing at two additional graphics cards to cover the mainstream ~$190 - $230 price range, with the GeForce GTX 660 and GTX 650 reportedly scheduled for release in September.
Similar to the GTX 670 and upcoming GTX 660 Ti, the non-Ti GTX 660 would be based on the GK104 core, but with 5 or 7 SMX units enabled for a total of 960 or 1152 CUDA cores. The card is expected to feature 2GB of GDDR5 memory along a 192-bit interface. Its expected price is $229.
Meanwhile, the GTX 650 appears to be a GT 640 with GDDR5 memory and improved clocks. It will reportedly feature the same GK107 chip as its lower-end sibling, with 384 CUDA cores clocked beyond 1GHz and 1GB of GDDR5 memory on a 128-bit bus. As it’s often the case, partners will be able allowed to custom-design their own variations of the card with extra memory and better coolers.
The GTX 650 is rumored to hit the market shelves on September 17 at a price range of $189-$199. Later in the year during Q4 Nvidia is said to be releasing an in-between model, the GeForce GTX 650 Ti, based on the GK107 with 960 active cores and 1 or 2 GB of memory on a 192-bit bus.
In the meantime those in the market for a ~$300 graphics card have the GeForce GTX 660 Ti to look forward to. TweakTown managed to get a sample and posted an early review of the card ahead of its official launch, and from the looks of it, AMD’s Radeon HD 7870 has some serious competition ahead.
The Nvidia GeForce GTX 680 contains four GPCs with a total of eight SMXs, 1536 CUDA cores, eight geometry units, four raster units, 128 texture units, and 32 ROP units. The base clock is 1006MHz, the GTX 680 also carries 2GB of GDDR5 VRAM running at 6008MHz with a 256-bit interface providing 6.0Gb/s of throughput. Dual six-pin power connectors feed the card's TDP of 195W.
The Nvidia GeForce GTX 690 features 3,072 CUDA cores, 4GB of GDDR5 RAM at 6.0Gbps running on a 512-bit bus and a base clock of 915MHz, although it can be boosted to 1019MHz. Video output is provided by three dual-link DVI ports and a single Mini-DisplayPort 1.2 output. Power is provided by two 8-pin connectors using a new 10-phase heavy duty power supply which is connected to a ten layer two-ounce copper PCB.
