Today at GTC NVIDIA announced their next GTX Titan family card. Dubbed the GTX Titan Z (no idea yet on why it’s Z), the card is NVIDIA's obligatory entry into the dual-GPU/single-card market, finally bringing NVIDIA’s flagship GK110 GPU into a dual-GPU desktop/workstation product.

While NVIDIA has not released the complete details about the product – in particular we don’t know precise clockspeeds or TDPs – we have been given some information on core configuration, memory, pricing, and availability.

In brief, the GTX Titan Z is a pair of fully enabled GK110 GPUs. NVIDIA isn’t cutting any SMXes or ROP partitions to bring down power consumption, so each half of the card is equivalent to a GTX 780 Ti or GTX Titan Black, operating at whatever (presumably lower) clockspeeds NVIDIA has picked. And although we don’t have precise clockspeeds, NVIDIA has quoted the card as having 8 TFLOPS of FP32 performance, which would put the GPU clockspeed at around 700MHz, nearly 200MHz below GTX Titan Black’s base clock (to say nothing of boost clocks).

On the memory front GTX Titan Z is configured with 12GB of VRAM, 6GB per GPU. NVIDIA’s consumer arm has also released the memory clockspeed specifications, telling us that the card won’t be making any compromises there, operating at the same 7GHz memory clockspeed of the GTX Titan Black. This being something of a big accomplishment given the minimal routing space a dual-GPU card provides.

In terms of build the GTX Titan Z shares a lot of similarities to NVIDIA’s previous generation dual-GPU card, the GTX 690. NVIDIA is keeping the split blower design, with a single axial fan pushing out air via both the front and the back of the card, essentially exhausting half the hot air and sending the other half back into the case. We haven’t had any hands-on time with the card, but NVIDIA is clearly staying with the black metal styling of the GTX Titan Black.

The other major unknown right now is power consumption. GTX Titan Black is rated for 250W, and meanwhile NVIDIA was able to get a pair of roughly 200W GTX 680s into the 300W GTX 690 (with reduced clockspeeds). So it’s not implausible that GTX Titan Z is a 375W card, but we’ll have to wait and see.

But perhaps the biggest shock will be price. The GTX Titan series has already straddled the prosumer line with its $1000/GPU pricing; GTX Titan was by far the fastest thing on the gaming market in the winter of 2013, while GTX Titan Black is a bit more professional-leaning due to the existence of the GTX 780 Ti. With GTX Titan Z, NVIDIA will be asking for a cool $3000 for the card, or three-times the price of a GTX Titan Black.

It goes without saying then that GTX Titan Z is aimed at an even more limited audience than the GTX Titan and GTX Titan Black. To be sure, NVIDIA is still targeting both gamers and compute users with this card, and since it is a GeForce card it will use the standard GeForce driver stack, but the $3000 price tag is much more within the realm of compute users than gamers. For gamers this may as well be a specialty card, like an Asus ARES.

Now for compute users this will still be an expensive card, but potentially very captivating. Per FLOP GTX Titan Black is still a better deal, but with compute users there is a far greater emphasis on density. Meanwhile the GTX Titan brand has by all accounts been a success for NVIDIA, selling more cards to compute users than they had ever expected, so a product like GTX Titan Z is more directly targeted at those users. I have no doubt that there are compute users who will be happy with it – like the original GTX Titan it’s far cheaper per FP64 FLOP than any Tesla card, maintaining its “budget compute” status – but I do wonder if part of the $3000 pricing is in reaction to GTX Titan undercutting Tesla sales.

Anyhow, we should have more details next month. NVIDIA tells us that they’re expecting to launch the card in April, so we would expect to hear more about it in the next few weeks.

    You are clearly not a gamer at all, much less one that runs a 2560x1440 screen at 120 Hz or multiple monitors, or both.

    No, you are wrong, think big: for 6-9 K$, you can have a true supercomputer that otherwise costs 5 million. Who is the greedy one here?
    Of course, this is a valid argument for you only If you need one.
    I do and this offer makes me happy. My palms are already sweaty :-)

    <This is a worthless card for gamers.>
    Absolutely! And I'm wondering what will happen with the professional cards Quadro and Tesla? Expend $ 3,000 for a GPU is really insanity! In the next future we'll see heavier applications, but for that time 20nm fab GPUs already will be released for 1/3 of that price, and then you'll regret it!

    I think the comparison is quite apt: this is this generation's ARES. Ridiculously niche, more of a showcase than anything.

    Double the card for triple the price. That's the Nvidia way!
  • Nagorak - Tuesday, March 25, 2014 - link

    Less than double since it has to be clocked lower.
  • The_Assimilator - Wednesday, March 26, 2014 - link

    So how's that dual-GPU Hawaii card working out for you?

    "I do wonder if part of the $3000 pricing is in reaction to GTX Titan undercutting Tesla sales." Yep, me too.

    Possibly, but if they've priced it too high for the pro market then it simply won't sell, plus it's not
    suitable for certain types of pro tasks anyway, eg. those that must have ECC RAM. Other pro
    tasks don't exploit 64fp, in which case the 6GB 780 makes more sense (though why the 6GB
    was put on a 780 and not a 780Ti I cannot figure).

    (sorry for the typo.. seriously, we still can't edit posts?)
