I don't know which world you live in, but as long as a company needs to sell, it needs to improve its products regularly for each price point...

The issue is not "min framerate" but high resolution-independant frame time, although I'm not sure it's real. In other words, significantly reduced pixel time as you increase resolution.

Cayman's performance inconsistency seems to have much to do with nVidia's developers program. Look at Lost Planet 2 and HAWX 2 for instance, AMD's performance are just abysmal here and Cayman didn't improve that much over Cypress, meaning Cypress' bottleneck in these games hasn't changed...

Price is just a variable you adjust based on actual product positioning. In terms of performance, HD6970 ~ GTX570 ~ GTX480, that's a fact. Power draw nearly identical to GTX570's is a fact, too. Higher noise, too, and price is almost the same, too. That's not ~30% faster than HD5870 but...

Products are NOT OK. Only the 6950 is barely OK (compared to 5870), 6970 isn't at all... 1- Barely better performance, similar perf/area. 2- Considerably worse perf/watt (~15%). 3- One year later. Cypress' bottlenecks don't seem to have been adressed except the back-end one, probably...

Let's be serious... Would you use "Class of its own" to describe something only barely higher than your own lower product? Would you if it were closer to your competitor's 30% faster board? The performance chart floating around is probably a fake because of this and we should probably...

I can imagine, easily. In that case, going for a slightly bigger die wouldn't have such an impact on yield nor on die candidates per wafer, but that would have given them the performance crown. Performance crown itself allows for a price premium of at least $50 per board, and brand...

As I said, because sweet-spot does work for a mainstream/performance part (regular gasoline in a regular car) doesn't mean it'll work for a "competition" part (same regular gasoline in a race car). The marketing name itself says Cayman is an Enthusiast product, and as such it doesn't obey the...

Then, there are some issues... I think it's your own projection. 1- Barts is very similar to RV770 in terms of size, cost and pricing (and if you look closely, it's horribly worse in the "normalized perf/mm²" department, it should be ~200mm²) 2- Barts ended up in the "6800" series...

The answer to that is quite simple. Cayman signs the comeback of single GPU enthusiast boards from AMD, so it doesn't have to be small, and in fact it had to be quite big unless sufficiently fast without that. Now, what was "sufficiently fast" about one year ahead when Cayman was being...

If its performance isn't at least ~40% better than Cypress, it'll have been crippled, whatever the reason. On the other hand, 20 VLIW4 SIMDs is enough to be even higher than that, so either it's crippled (low specs, low perf) or more efficient (low spec, high perf). Limiting the SIMD count...

No, it doesn't. Consider the "1600" GPU-Z gives on that board, it means it has 1280SP if based on NI, or 1600 if based on EG. Either it's Cypress in disguise, severely crippled Cayman or Cayman dramatically reduced raw throughput in exchange for efficiency (theorically, with 20 VLIW4...

HD5970 "Fastest Enthusiast board" > GTX580 > HD6970 "Best Enthusiast GPU" > GTX570 is clearly strange. If Cayman ends up being a "small" die with minor improvements (perf/mm², tessellation performance) and even some pitfalls (perf/watt with 190 watt playing games) compared to Cypress, it will...

It seems like some S|A forum's comment about AMD sending fake presentations is true... How could a board between HD6870 and GTX480/570 be in "a class of its own"? Theres something like a 30% advantage for the GTX480/570, so it's either too slow to be worth producing (less than 20% faster) or...

It would be quite interesting to do an in-depth analysis with this particular benchmark, as it seems to allow for a fine tuning of tessellation and, quite importantly, uses a more "real world" workload than any other DX11 synthetic benchmark. I'm still quite disappointed by the low...
