Alongside the Titan X, NVIDIA has announced the Quadro M6000. In terms of hardware, they are basically the same component: 12 GB of GDDR5 on a 384-bit memory bus, 3072 CUDA cores, and a reduction in double precision performance to 1/32nd of its single precision. The memory, but not the cache, is capable of ECC (error-correction) for enterprises who do not want a stray photon to mess up their computation. That might be the only hardware difference between it and the Titan X.
Compared to other Quadro cards, it loses some double precision performance as mentioned earlier, but it will be an upgrade in single precision (FP32). The add-in board connects to the power supply with just a single eight-pin plug. Technically, with its 250W TDP, it is slightly over the rating for one eight-pin PCIe connector, but NVIDIA told Anandtech that they're confident that it won't matter for the card's intended systems.
That is probably true, but I wouldn't put it past someone to do something spiteful given recent events.
The lack of double precision performance (IEEE 754 FP64) could be disappointing for some. While NVIDIA would definitely know their own market better than I do, I was under the impression that a common workstation system for GPU compute was a Quadro driving a few Teslas (such as two of these). It would seem weird for a company to have such a high-end GPU be paired with Teslas that have such a significant difference in FP64 compute. I wonder what this means for the Tesla line, and whether we will see a variant of Maxwell with a large boost in 64-bit performance, or if that line will be in an awkward place until Pascal.
Or maybe not? Maybe NVIDIA is planning to launch products based on an unannounced, FP64-focused architecture? The aim could be to let the Quadro deal with the heavy FP32 calculations, while the customer could opt to load co-processors according to their double precision needs? It's an interesting thought as I sit here at my computer musing to myself, but then I immediately wonder why did they not announce it at GTC if that is the case? If that is the case, and honestly I doubt it because I'm just typing unfiltered thoughts here, you would think they would kind-of need to be sold together. Or maybe not. I don't know.
Pricing and availability is not currently known, except that it is “soon”.
