We were informed that the blocks use a new production technique that makes them lighter and better-performing than existing all-metal, CNC-machined blocks.
The basis of the design is a hybrid injection-moulded plastic that's screwed on to the all-copper heatspreader and micro-channel fluid heat exchanger (FHE).
The GTX 285's block is shown below, and the entire card is lighter than a regular watercooled model.
And it fitted into a showcase system, alongside a Domino CPU pump/reservoir and control unit.
We doubt that the GTX 285 iteration will see the light of day, simply because that GPU's value proposition is poor to begin with. The GTX 295 version may have some legs, but we'll have to wait on pricing and performance before passing judgement on it.
