Despite a last-minute delay, Nvidia has officially launched its GeForce GTX Titan Z graphics card - described by the company as 'the fastest and most advanced graphics card' it has ever made - in the UK.
Unveiled by Nvidia's Jen-Hsun Huang at the company's GPU Technology Conference (GTC) back in March
, the GeForce GTX Titan Z is designed to sit very firmly at the top end of the consumer graphics card spectrum. Featuring a pair of GK110 GTX Titan Black graphics processors with 6GB of 7Gb/s memory each, a custom-designed 12-phase power supply featuring dynamic power balancing and 5,760 CUDA cores without the usual double-precision performance crippling found in consumer-grade graphics cards, there's little denying the Titan Z is a beast.
The GPUs are clocked at 705MHz as standard, boosting to 876MHz when possible, while the memory is connected over a pair of 384-bit buses - one for each GPU. The triple-slot card includes a single dual-link DVI-I connector, another dual-link DVI-D, an HDMI connector and a DisplayPort connector, with support for four displayu and a maximum resolution of 4,096x2,160. It's powered by a pair of eight-pin PCIe power connectors, with Nvidia claiming a 375W thermal design profile (TDP) and recommending that the cards are used with a 700W power supply as a bare minimum.
Nvidia's usual board partners have announced boards based on the company's reference design, with Asus and Gainward offering UK stock ready for shipping and Gigabyte, MSI, Zotac and EVGA offering pre-orders at most retailers. Pricing is set at an eye-watering £2,399.99 across the board, with the exception of the oddly discounted Gainward model which is available from Overclockers UK for a still-not-quite-a-bargain £2,329.99.
Nvidia's pricing may be high, but its unlocking of the double-precision floating point performance could nevertheless spell success: typically, to get full-performance double-precision requires the company's high-performance computing (HPC) product lines which cost considerably more. Without the same enterprise-grade support, however, it's hard to see the Titan Z making inroads into the supercomputing sector unless pricing drops considerably.
