As always, there are going to be a plethora of rumors about the next GPUs coming from AMD and Nvidia, so it comes as no surprise that new details are leaking about Nvidia’s next generation of GPUs based on Maxwell. Nvidia has already launched the Maxwell architecture with the incredibly efficient and modular GTX 750 Ti. However, this is their one and only Maxwell part and there are lots of people wondering when we’ll see the mid and high-end parts.

So, today’s rumor, about the GeForce GTX 880 and GTX 870 are clearly feeding off of this desire for information and likely enlighten when and what we can expect to see from Nvidia. The first and foremost important detail is that their sources claim that the GeForce GTX 880 and GTX 870 will be launching in the fourth quarter of 2014, most likely in October or November. This would give Nvidia ample time to prepare for the fall/winter game release rush and to have a new and exciting product for the holiday season.

Also, as expected this part will still be based upon the 28nm process from TSMC as the countless rumors of TSMC’s 20nm delays seem to never end. While we all believe that both AMD and Nvidia would love to manufacture their latest generation of high-end GPUs on TSMC’s 20nm process, it simply does not appear to be ready for their multi-billion transistor chips. Let’s remember that Nvidia’s GK-110 is actually a 7.1 billion transistor chip and there is a very strong liklihood that a Maxwell part like what we would expect to be the GM-110 is very likely going to be a GTX 9 series part and not a GeForce GTX 880.

As we saw from Nvidia in the past, they generally launch a cut-down version of the architecture first like the GTX 680 (GK104) and then once their process is more mature and their thermals/yields are manageable, then you’ll see a GTX 780 Ti (GK110) that fully follows the ‘full-blown’ architecture design without any compromises. A lot of sites are referring to the Maxwell batch of GPUs as GM204 and GM-210 however there is no reason to believe that Nvidia would do this, especially since the GTX 750 Ti is a GM107 chip. If the process hasn’t changed and the architecture is the same, I don’t see any reason why the GeForce GTX 880 could not be a GM-104 with its full-blown successor being a GM110 or GM210 if they decide to go with the 20nm die shrink (very likely).

However, some of the rumors continually refer to the high-end GPUs as GM204, which leads some people to believe that we may see more than just higher performance out of a GeForce GTX 880 or GTX 870 part. Realistically, though, I don’t really see this being possible and those parts may be reserved for professional or HPC applications that will get released shortly after the GeForce GTX 880.

We were a bit surprised to see an announcement on Techpowerup! that ASUS had launched their GTX Titan Z without any hoopla from Nvidia or any of their other board partners. So, it comes as little surprise that the article itself has since been pulled and that any and all mentions of ASUS’ GTX Titan Z have disappeared. But of course, the damage has already been done and Pandora’s box has been opened. However, there isn’t that much about this card that is really a mystery.

The GTX Titan Z is expected to be a dual Titan graphics card, air cooled, that enables some of the best dual precision compute performance on earth while still delivering an incredible gaming experience, all while doing it with only one graphics card. This is possible because of the dual GPUs and 12 GB of RAM, which in theory would make the Titan Z a possibly better single card solution for driving three 4K monitors simultaneously. Obviously, based on our findings with the AMD R9 295X2, the likelihood of driving all three of those 4K monitors while gaming is out of the question, but driving a single 4K monitor is very likely possible if not encouraged. What’s more interesting is that Nvidia told us the price of the GTX Titan Z before we actually knew anything else about the card and as a result, it costs as much as two of AMD’s latest high-end GPU, the R9 295X2 at $3,000 a pop.

ASUS GTX Titan Z

Based on what we saw from Techpowerup, the ASUS card will have its own real-time graphics tuning utility called GPU Tweak to allow on-the-fly adjustments, even though I don’t know many people that need to make on-the-fly adjustments to a $3,000 card. Remember, this isn’t quite a professional card, but it also isn’t quite a gaming card since it is $3,000 and that takes it out of the reach of about 99.99% of gamers. It will also have each GPU running at a base clock of  705 MHz and a boost clock of 876 MHz, meaning that this card is significantly slower per GPU than its single GPU counterparts, which isn’t necessarily unexpected considering the TDP of each GPU. With both GPUs and memory combined, this card will have a total of 12 GB of GDDR5 memory and 5760 CUDA cores, which are what this card is designed to deliver, lots of memory and lots of cores.

According to the Techpowerup! article this GPU is supposed to be available worldwide on April 29th, yesterday. However, we’re hearing that there is a slight delay with this card and that date has been pushed back to May 8th, essentially a week away from tomorrow. Which may explain why ASUS had Techpowerup pull the article and why there is no news about it, Techpowerup may have just not gotten the memo.
