Still on 28nm, but more power efficient than their predececors in games.

Nvidia is kinda "steady" now. They seem like not moving anymore, or moving very slow. They announced us in the weekly letter (we are "consumers" of their Tegra chips for our industrial terminals) that Tegra3 availability and support is extended, and guaranteed until 2015. This is good for us like industrial manufacturer, but bad for me as mersenne cruncher, it smells like they are either not trying new designs, or tried and failed (just a hunch, hehe). Both Titan and R9-295x2 are hard to beat... Anyhow, doing this announcement about T3 when they already have T4 on the market it can be either a marketing trick/strategy, or either a big mistake...

Tegra 3 is now a moderately old chip (launch late 2011); since then the T4 and the TK1 are out. The TK1 is really not that bad a processor; I have a four-core TK1 devboard at home, it is only an order of magnitude slower than a quad-core Haswell at ECM, and only about a factor three slower than the Haswell at running msieve.

How did you get your hands on a GTX 900 so fast?

It seemed to me like the GTX 770 was the sweet spot for GPU computing in terms of performance per dollar (that might have been specifically for CUDALucas, though). Now the GTX 970 is considerably better and actually a good bit cheaper at release.

For mfaktc, GTX 580 is still the best. It gives a little more performance than the GTX 970 at one third the price on the used market. But if you're paying for electricity, the GTX 980 is easily the best to buy now.

Is the memory compression feature of any use at all in CUDALucas? I'm kind of thinking "No" because it's a colour thing.
