Nvidia’s new graphics card is $3,000, painted gold, and not meant for graphics

Although Nvidia launched its 21 billion transistor Volta GPU architecture back in May, until now the chip has been used exclusively in compute cards—specifically, the Tesla V100 cards, which cost about $10,000 for the PCIe version. But now Volta GPU is available in a graphics card: at the 2017 Neural Information Processing Systems conference, Nvidia CEO Jen-Hsun Huang announced the Titan V, a $3,000 golden video card making the same GPU—the Volta architecture GV100—available to regular end users.

Unlike the Tesla cards, the Titan V is a proper graphics card. It has three DisplayPort and one HDMI outputs, it uses the standard GeForce driver stack, and it will play games. It'll probably play them quite well, although Nvidia hasn't made any gaming performance claims thus far. That's because, although it's a graphics card, it's not really being aimed at graphics applications. Rather, it's being aimed at the same kinds of GPU-based computation (especially machine learning) applications that the Tesla cards are meant for, just on a slightly smaller scale. Titan V would be used in a workstation PC, rather than a compute cluster in a datacenter.

With these similar roles in mind, it's not too surprising that Titan V's specs are extremely similar to Tesla V100's. Both cards have 5,120 compute cores, and both have 640 machine learning-oriented "tensor cores" that specialize in 4×4 matrix arithmetic. Exact clock speeds for the Tesla cards aren't known, but Titan V can boost to 1.455GHz, slightly more than V100's 1.370GHz. It's the memory subsystem that has the biggest difference: Titan V has 12GB of HBM2 memory, with a 3,072-bit memory bus. Tesla V100 has 16GB of HBM2 and a 4,096-bit bus. The Titan's memory is also a hair slower, clocked at 1.70Gb/s compared to 1.75Gb/s.

Taken together, the new card has almost identical computational performance—13.8 trillion single precision floating point operations per second, 6.9 double precision TFLOPS, and 110 reduced precision machine learning TFLOPS in Titan V, compared to 14 single precision, seven double precision, and 112 machine learning TFLOPS on V100—but with memory bandwidth of a mere 653GB/s, compared to 900GB/s for the compute card.

For that price everyone can buy two and run them in SLI!

I paid less for my car than what that thing costs. :lol:
In the 60's, people took acid to make the world weird. Now the world is weird and people take Prozac to make it normal.
