Although Nvidia Corp. was expected to begin sales of the GeForce GTX Titan Z dual-chip graphics card on Tuesday, partners of the company did not start to sell the new flagship graphics solution. According to several media reports, Nvidia decided to postpone the release of the GeForce GTX Titan Z to a later date.

Nvidia announced its GeForce GTX Titan Z graphics card based on two GK110 graphics processing units in late March, 2014, but disclosed neither precise specifications nor official launch date. Last week it was reported that the graphics board, which price-tag will start at $3000 (£2331, €2834) without taxes, will finally hit the market on Tuesday, the 29th of April. Unfortunately, now it does not look so: the graphics solution is unavailable in Japan, Europe and the U.S.

According to SweClockers web-site, resellers still have not received the GeForce GTX Titan Z graphics boards and Nvidia now intends to release the high-end graphics solution at a later date. VideoCardz.com web-site also reports that the GeForce GTX Titan Z is postponed indefinitely.

Nvidia GeForce GTX Titan Z is powered by two Nvidia GK110 graphics processors in their maximum configuration with 2880 stream processors (as well as 240 texture units and 48 raster operations pipelines), which gives the solution 5760 compute units in total to offer whopping 8TFLOPS of single-precision compute performance. The board is equipped with 12GB of GDDR5 memory (6GB with 384-bit bus per GPU). Unfortunately, Nvidia did not reveal actual GPU frequency of the GTX Titan Z a month ago. According to some reports, the clock-rate of the two GK110 chips on the Titan Z will be 695MHz – 730MHz, considerably lower than 875MHz GPU clock-rate of the GeForce GTX 780 Ti. Moreover, in a bid to ensure stability, Nvidia reportedly had to lower memory frequency from 7GHz to 6GHz and install a special back-plate on the back-side of the card to cool-down memory chips.

The situation with the GeForce GTX Titan Z’s availability remains largely unclear. At present it does not even look like Nvidia has made its mind regarding exact specifications of the product. Since specs affect performance, the company cannot just offer the GTX Titan Z for $3000 and upwards in case the solution is not the world’s highest-performing graphics card. All-in-all, Nvidia needs to finalise the specs, finalise the price and only then start to sell.

Nvidia did not comment on the news-story.

KitGuru Says: It looks like this time AMD’s dual-chip flagship graphics board – the Radeon R9 295X2 – will remain alone on the market for a while. So, if you want the world’s fastest graphics card, you know what to buy.
