Think we've been hearing this one for the last 4 years. CUDA won't disappear anytime soon because its much more robust than its nearest competitors. The Intel Phi is a threat for sure but its perf/w is laughable.
Plus, its not the theoretical maximum FLOPs that matters but how you achieve it. There is a reason why AMD based cards dont jive well with GPGPU programmers outside a few applications. I mean, what is luxmark and how does this relate to the real world apps? Its also based on OpenCL which nVIDIA gives minimal support/performance optimizations.
If everything was based on pure theoretical numbers alone, the Tesla/CUDA/Quadro market would cease to exist. Except in the real world, this is far from the truth.
However the 3K price tag is a little too extreme.
I`ve been saying this many times too and people just don`t get it or enjoy trolling the forums.
For people with software and algorithm that is optimized for CUDA, the price premium for any CUDA card far outweigh the cost it would be to convert their workflow for AMD and their cards. But not even that is a possible option for many professionals.
AMD may be "killing Nvidia" on gaming with R9 295X2 being much cheaper, but a lot of people still rely on CUDA and have no other choice than buying Nvidia cards. That said, Nvidia isn`t forcing anyone to buy Titan Z anyway, since GTX Titan Black in SLI would still be much cheaper and offer better performance (Fully unlocked 1/3 FP32) than Titan Z.
The exact same can be said about R9 290X in CF, which is $400 cheaper than 295X2.
Both R9 295X2 and Titan Z are just an attempt at milking the market anyway, in wait for the next architectures which are LONG overdue, which anyone who follow the GPU scene knows, and one should assume that both companies therefor have sales expectations accordingly.
I agree that the price for Titan Z should maybe come down, but one have to put it in a little perspective:
2 * 290X : $1100
295X2: $1500
2 * Titan Black: $2200
Titan Z: $3000
This price model is obviously tailored for GPGPU people, hence why both Titan Black and Titan Z are exactly 2x the cost of the AMD alternative.
GTX 780 Ti are at $700 and are for gamers since the FP64 cores are mostly disabled.
This price strategy is exactly in line with what Nvidia have been doing the whole time. Milking the CUDA clients with a hefty price premium while placing the gamer cards a little above the competition.
I don`t understand why people even care and keep whining. I get it if you are running a small desktop with only room for one graphic card, but for the rest, buy 2 * 780 Ti instead. Much cheaper. If anything, Nvidia is doing you a favour in scaring you away from Titan Z. I don`t think anyone should dish out for any graphic card now anyway, since both Maxwell and the next architecture from AMD is just around the corner. All the recent cards are just a big MEH and nothing new.
Its actually a bit desperate if you ask me and I think both AMD and Nvidia know they won`t move so many units of these cards.
