Although Nvidia Corp. and its partners did not release the GeForce GTX Titan Z dual-GPU graphics card this week, they plan to start selling the flagship graphics solution next week, according to media reports. As expected, the GTX Titan Z will not be as fast as two GTX Titan Black graphics boards because of lowered clock-rates, still, it should be very fast in games.
Instead of the 29th of April, the GeForce GTX Titan Z graphics card powered by two GK110 graphics processing units (GPUs) will arrive on the 8th of May, reports Hermitage Akihabara. The graphics solution will cost starting from $3000 (£2330, €2835) without taxes, just as Nvidia announced back in March. The reasons for the delay were not revealed.
As previously reported, 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. In a bid to properly cool-down two GPUs the developer had to slow-down their clock-rates to 705MHz in default mode and 889MHz in “boost” mode, which is lower compared to the frequencies of the single-chip GeForce GTX Titan Black (889MHz/980MHz). The board is equipped with 12GB of GDDR5 memory (6GB with 384-bit bus per GPU) that will be clocked at 7.0GHz, as reported initially.
Chinese JD.com web-site has also published an image of the GeForce GTX Titan Z graphics card without a cooler, revealing a rather complex design with two GK110 GPUs, 24 memory chips (another 24 are located on the back side), a PLX PCI Express bridge chip and two 8-pin PCIe power connectors (which means that the card can consume up to 375W of power). In a bid to simplify the design a bit (probably because there is not a lot of space on the PCB), Nvidia decided to use five-phase voltage regulator module (VRM) for each GPU + memory pair instead of six-phase VRM on the GeForce GTX Titan.
It looks like nearly all the secrets of the GeForce GTX Titan Z are now revealed. While the new dual-GPU graphics card will provide 8TFLOPS of single-precision compute performance, two GeForce GTX Titan Black boards already offer whopping 10TFLOPS of computepower, at a lower price-point. Therefore, unless Nvidia implemented certain SLI enhancements on the GeForce GTX Titan Z that greatly improve efficiency of its multi-GPU technology, two of already available solutions will be faster than the upcoming dual-GPU graphics board.

KitGuru Says: The GeForce GTX Titan Z will clearly find its buyer despite of a direct rival in the face of the Radeon R9 295X2 graphics card, massive price and performance that is lower compared to already available dual-GPU setups. However, it is hard to expect that there will be a lot of buyers for this one…
