Yeah but they describe HBAO+ a fair bit (interleaved rendering+IIRC some temporal reprojection)... it's not hard to understand what's going on.

And like I said, ultimately it doesn't matter if...

HBAO has been described enough in the original paper and follow-up tech reports for someone to implement it themselves. In fact, haven't folks already done this? The GameWorks implementation would...

It's a simple question of power. Even at 65W you obviously can't run 4 cores + GT3e GPU at max turbo all at the same time. Otherwise there'd be no point in the 84W TDP on desktop CPUs (that have half...

Completely depends on what you mean by "all shading effects on" :) You obviously shouldn't expect it to be as fast as a 200W discrete GPU or anything, but depending on your definition of "casual",...

So is that striped across the address space then? Any idea what the stripe size is? Just trying to figure out if really you'd get much more multi-rank stuff from a 2 slice vs. 1 slice part.

Interesting idea - the screen is statically split into tiles across the two slices so you'll definitely get somewhat more scattered access in GT3 from that point of view (both ROP and memory reads...

I think it does things like control how big the "brilinear" region is, etc. but I'm not 100% sure on the comprehensive list. I'll dig and let you know what I find out :)

The 4670k is a GT2 GPU whereas the one Intel tested is GT3 (i.e. twice as big). It's definitely expected that the latter will be much more significantly bottlenecked by DRAM bandwidth than the...

IIRC RGBA16f is half speed in ROPs and maybe trilinear too (when not in the brilinear zone) although the latter probably doesn't apply to light accumulation. I think it actually has the same blend...

Correct, although somewhat more confusingly there is no "feature level 11_2"... but yes you can be a feature level 11_1 device and not support tiled resources at all, as is the case for Haswell.
