14 DAY TRIAL // When we saw that EVGA had released two NVIDIA GeForce GTX 780 graphics cards with waterblocks, we suspected one stuck to reference clocks and the other was factory overclocked, but that is not the case.
In fact, both cards have factory-overclocked graphics processing units, even if the memory is left alone.
The EVGA GeForce GTX 780 with Hydro Copper operates at 980 MHz most of the time and 1,033 MHz in a pinch.
Compared to the standard 863 / 900 MHz clock speeds, that is quite a leap.
Meanwhile, the GTX 780 Classified with Hydro Copper Watercooler will probably be faster than even the normal Hydro Copper card.
We can't know for sure though, since the speed settings haven't been announced yet. EVGA has a nice product page here, with both of them, but even there, the Clock setting says “TBA.”
Anyway, the 3 GB of GDDR5 work at 6 GHz in both cases, over a memory interface of 384 bits. The bandwidth is of 288.38 GB/s.
As for the cooler itself (or the cooler component, since waterblocks can do nothing without a full system made of a reservoir, pumps and water), it covers everything on the PCB that produces heat (GPU, memory chips, VRM). The main material is chrome-plated C110 copper.
For those who want more specifics, the waterblock uses a thin-pin matrix too, as well as swappable Inlet/Outlet, custom compression fittings (both 3/8" and 1/2" compression fittings, no hose clamps required) and a glowing EVGA logo on top.
Needless to say, all the Key NVIDIA technologies are supported:
NVIDIA TXAA Technology NVIDIA GPU Boost 2.0 NVIDIA PhysX Technology NVIDIA FXAA Technology NVIDIA Adaptive Vertical Sync NVIDIA Surround Support for four concurrent displays; two dual-link DVI connectors, HDMI and DisplayPort 1.2
EVGA hasn't released the prices of the card yet, although some retailers may begin listing the items soon, if they haven't already.
