Titan is a consumer grade part, the server grade parts cost multiple times more.
I dunno. The Titan supercomputer cost $60 million and has 18,688 K20X's , but it also has 18,688 Opteron 6274's, 598 TB RAM and 10PB storage. If you figure the GPU's made up half the cost, that's only $1603 each.
That's incorrect. Titan is a GK110 chip like the Teslas. The 690 and lesser series use chips that are half the size and as a result have different chip names.
The K10 uses the GK104. Are the GTX 690, 680, 670, and 660Ti not consumer grade cards?
The M2090, M2070, and M2050 use the GF110. Are the GTX 590, 580, 570, and 560Ti 448 Cores not consumer grade cards?
The C2050, 2070, and 2090 use the GF100, Are the GTX 480, 470, and 465 not consumer grade cards?
The C1060 was GT200, I believe. Were the GTX 260 275, 280, 285, and 295 not consumer grade cards?
