MSI GTX 950 2GD5T triangles per second A friend got an MSI GTX 950 2GD5T graphics card for xmas.

I said "yeah, graphics cards are super fast now, that thing probably processes 2 billion triangles per second". Then I tried to look it up to check if that was even in the right ballpark, but I was unable to find a "triangles per second" stat for that card, and actually for many cards.

Is "triangles per second" even a meaningful stat? If so, what is the approximate number for this card? (given otherwise average conditions)
Yes, it's a meaningful stat: GPUs have dedicated triangle setup HW and the rate is measured in triangles/GPU clock. According to white papers available on NV's website, the 680 (Kepler) could issue one triangle per SM every other clock - with 8 SMs, this yielded 4 triangles/clock. The Maxwell white paper doesn't indicate a change in this rate per SM - the 980 has 16 SMs so, if there is really is no rate change per SM, it can produce 8 triangles/clock. While the 980 has 2048 CUDA cores, the 950 has 768, implying 6 SMs and 3 triangles/clock. The chip runs around 1 Ghz, so the 950 is probably limited to 3 billion triangles per second.
