Atlantico: forget it, why even bother.
ET3D: You didn't bother. You didn't give even a single example. That's a classic line of someone clueless.
Edit: What I mean is: please give an example where knowing of a specific architectural feature should make a significant difference to a buying decision based purely on benchmarks.
"should" or "would"? :p
Example: compute performance on nvidia quadro cards tends to be a lot higher than on geforce cards (or, in certain scenarios, the gtx cards tilt and crash). But that's also the case even when these two models actually use the same chipset. The reason for that is simply that the instruction queue scheduler on the gtx cards doesn't exist. So with current chipset production, the basic difference between a 1000 dollar card and a 100 dollar card is a software/firmware layer and a laser-cut for some of the lanes.
Does this make a difference to someone playing Call of Duty with FSAAx16 on top of the same blurry texture supersampled for precision 32 times? No. Should it make a difference considering how relevant OpenCL and other compute-type platforms are going to be soon? Maybe.
Another example: So it turns out that the ram "speed" on graphics cards is actually very, very low. And that the simd principles graphics card operations run on essentially makes that comparatively low access speed both optimal and necessary. If people knew a lot about gddr5 and ddrx4awesome standards, and so on, then they'd know that going from "ddr3" to gddr4 and gddr5xsupreawesome... really was a complete PR blitz. It had nothing to do with higher speed, and a lot to do with manufacturers wanting to get rid of gddr memory modules manufactured in bulk for different applications than just for graphics cards. They saved money on manufacturing, and sold the card for more money! And it used a lot more power, and memory bus architecture optimisations made it difficult to compare with the previous cards, so everything's great. Except for us, who are paying for this crap, and in so doing essentially stalling already scheduled architecture improvements. Because yay, gddr5awesome!
Should stuff like that matter? Anandtech and gawker doesn't think so, so I guess not.
