CHIP DESIGNER Nvidia has refreshed its range topping single GPU enthusiast graphics card with the 2,304 core Geforce GTX 780.
Nvidia's Geforce GTX 680 was announced over a year ago and competed against AMD's Radeon HD 7970 and more recently Radeon HD 7970 GHz edition. While AMD has stuck with its Radeon HD 7970, Nvidia has launched a preemptive strike with its Geforce GTX 780, based on the same Kepler architecture as its predecessors but with a bump in memory to 3GB.
With Nvidia sticking to its Kepler architecture for the Geforce GTX 780, the firm isn't promoting Earth shattering performance figures but a steady increase in performance. On the specifications sheet, Nvidia's Geforce GTX 780 looks like a fair refresh, with 2.304 cores clocked at 863MHz that can be boosted to 900MHz.
Nvidia also touts impressive 4TFLOPS single precision floating point performance from those 2,304 cores. However Nvidia's decision to bump onboard memory from 2GB to 3GB of GDDR5 384-bit memory is perhaps the most important upgrade for those that run multi-display setups.
While Nvidia's Geforce GTX Titan will remain at the top of the firm's single GPU board selection, its high price puts it out of reach of most enthusiasts and gamers. The firm's Geforce GTX 780 doesn't come cheap at £550, but it is a whole lot more affordable than a GTX Titan, which goes for £800.
As for AMD's Radeon HD 7970, cards are available around £300, putting it in a completely different price bracket and also bringing up the possibility of buying two boards and running them in Crossfire configuration.
However with Nvidia refreshing its Kepler GPU architecture, it seems unlikely that AMD will keep its Radeon HD 8000 brand laptop parts on the market for much longer. µ
