To get double precision, you just need the FP64 multiplier, except in Titan's case also revise the GPU clock since it drops to 725mhz in FP64.

The penalty for enabling full speed FP64 mode is that NVIDIA has to reduce clockspeeds to keep everything within spec. For our sample card this manifests itself as GPU Boost being disabled, forcing our card to run at 837MHz (or lower) at all times. And while we haven't seen it first-hand, NVIDIA tells us that in particularly TDP constrained situations Titan can drop below the base clock to as low as 725MHz. This is why NVIDIA’s official compute performance figures are 4.5 TFLOPS for FP32, but only 1.3 TFLOPS for FP64. The former is calculated around the base clock speed, while the latter is calculated around the worst case clockspeed of 725MHz. The actual execution rate is still 1/3.

For the premium they are charging it should have a nice aluminum backplate. Exposed PCB? C'mon! I thought it was ridiculous with the 690 as well. EVGA finally got the $25 backplates in stock, but again (IMHO) they should be standard for this caliber of hardware!

As for the back side of the card, keeping with most of NVIDIA’s cards Titan runs with a bare back. The GDDR5 RAM chips don’t require any kind of additional cooling, and a metal backplate while making for a great feeling card, occupies precious space that would otherwise impede cooling in tight spaces.

Locking this one - let's move the discussion into the sticky thread.
