Nvidia's GK110 GPU, otherwise known as Big Kepler, may soon be coming to a consumer-oriented graphics card. The chip has thus far been reserved for enterprise-grade Tesla products. However, Sweclockers quotes multiple sources as saying the top rung in the Kepler ladder will power a GeForce Titan card due to be released in March. According to the site, the card will cost an eye-popping $899 and offer 85% of the performance of the GeForce GTX 690.
The GTX 690 is this generation's SLI-on-a-stick; it features dual GK104 GPUs from the GeForce GTX 680 and costs about a grand. Given that context, offering 85% of the performance for 90% of the price doesn't sound all that unreasonable.
Although the GeForce Titan's specifications are unknown, it's worth noting that the GK110 implementation in Nvidia's flagship Tesla K20X isn't a full-fat affair. In that product, one of GK110's 15 SMX units is disabled, and the clock speed is only 732MHz. GK104 is clocked from 915-1006MHz in the GeForce GTX 680 and 690, although the chip has only eight SMX units. GK110 also enjoys a much wider memory interface than GK104: 384 bits versus 256.
Ultra-high-end graphics cards may have little appeal to budget-conscious enthusiasts, but everything we've heard suggests that these kinds of products routinely sell out. Halo products are all about image, too, and Nvidia will want to have something to counter the 8000-series Radeons rumored to be just around the corner.
