midrange, true high-end... never heard it before?
You are really trying to be deceptive with that comment. Even though NV improved efficiency of memory bandwidth by at least 30%, 256-bit on Maxwell is mid-range, 398mm2 GM204 is mid-range in the Maxwell stack, and its performance for a next gen 970/980 product is just mid-range 960Ti/970 level, not 980 = end of story. We know this is not the real flagship Maxwell card over the next 2 years until Pascal; and even NV primarily compares 980 to GK104 680 in its marketing slides as an upgrade replacement.
Obviously it's pointless to say that 512-bit bus on 2900XT makes that card high end vs. 256-bit 970. When we discuss the limitations of 256-bit bus, it's in relation to NV's Maxwell stack overall. The delta compression benefits will apply to GM210 just as well and that card will surely have a wider than 256-bit bus. Even though 980 keeps up with 780Ti/290X at 4K, it is
only 7-8% faster, which changes
nothing about 4K gaming playability for single GPUs. What's revolutionary here are 970 SLI bang-for-the-buck, some HTPC features such as HDMI 2.0 finally hitting mainstream, and perf/watt on the same 28nm.
As far as moving the absolute performance level from 780/780TI, 970/980 are nothing special from what was available 1 year ago. It's just that 970 brings 90% of 780Ti's performance at $330.
Now they are touting compression similarly as Nvidia.
Except AMD introduced this tech before NV with 285 so the statement should be NV is touting compression tech similar to AMD.
I have a feeling on AMD's line your going to see a huge amount of products now between the $200-350 range compared to before. I feel like there is going to be a lot of redundancy there, though.
1) A 354mm2 R9 280 has seen drops to $180 for a while so a cheaper to manufacture 256-bit bus Tonga 285 should be $169.
2) R9 280X has seen prices of $240-260 for months so if AMD officially drops it to $219, and that's $110 less over 970 and R9 280X. 960 priced at $229 could really kill 285/280X sales though. If R9 280X is $219, then it will offer
better performance/$ than a $329 970.
3) If AMD moves R9 290 to $269, there is still a market for it I think since performance of after-market 290s is pretty close to the 970. A lot of people look at R9 290 level of performance (~Titan/780) and keep thinking $500-650 but R9 290 came out at $399 and it's been 1 year since it came out. Surely AMD can afford to cut prices on that card.
