Well for your information this is not the thread:
"OMG the 400mm2 970 is the best thing since sliced bread its 20% faster than the year old 290 of similar size - just remember to have two 6 pins and a 550w powersupply"
We actually have 3 more or less similar threads to that - and fine for me, thats tech enthusiasm. Thats appriciation.
This is the thread:
[OMG ...insert yourself]
"What will be AMD´S next move?"
This is something entirely different. And its not "appriciation".
Yep, seems this thread was a not-so-camouflaged attempt at claiming AMD, for a billionth time in their history, is doomed. Except not only they are not doomed, they are actually in a better possition than 7970 vs 680 2 years ago.
7970 vs 680
20% larger die (50% larger bus bandwith)
10-15% perf advantage for the 680
10% higher price for the 7970 (12.5% higher price for the 7950vs 670)
50% more VRAM for the 7970
15-20% delta perf watt in gaming (0% perf/watt difference in GPGPU)
new uarch for both companies (3 months difference between each product)
290x vs 980
10% larger die (100% larger bus bandwith)
15-20% perf advantage for the 980
0% pricing difference (21.21% higher price for the 290 vs 970)
Same ammounts of VRAM for both cards
30-40% perf/watt in gaming (0% perf/watt difference in GPGPU)
NVs new uarch vs amd's n-1 uarch (1 year difference between each product)
This shows that from a cost standpoint, AMD is better suited this time to lower 290/x prices than they were on 7970 launch (less die size difference even sporting a bigger bus bandwith difference, same ammounts of VRAM for both companies now vs 50% more VRAM for the 7970 vs 680, etc).
From the gaming efficiency standpoint there isnt much to be done as now AMD is competing to a quite newer product compared to tahiti launch, which can be said it was pretty even in this regard. That said, I have seen Tom's power analysis on Hawaii and their power consumption spikes (240-50 average with spikes to 420) have a lesser average to spike ratio than what has been seen on GM204 (170 avg and 290 spikes), and both will require you to have a pretty well built power supply to endure that kind of spiking delta. It is obviously easier to build a SLI of GM204 than it is for Hawaii, no doubt about it.
The answer in the end is pretty simple: AMD is not going anywhere, the hysteria indeed is disproportionate (and is coming from the usual suspects as always), but what is important is that this competition is good for us as costumers as this launch will obviously lead AMD to adjust their Hawaii pricing (which is easier for them this time compared to the Tahiti vs GK104 situation a long while ago, because of the points shown above). They will still be behind in perf watt, something expected from a newer uarch vs a 1yr old one. But hey, if GCN 1.2 changes regarding tesselation and bus bandwith efficiency are any indicator, it shows that they are trying to catch up in every indicator they were actually behind, while still focusing in the thing that will actually make them make more money, which is GPGPU and the professional market.
EDIT: Something I forgot: Bus bandwith is a bigger die area cost incurred by whoever implements it. However, it allows you to use lower binned VRAM modules, which also impact in the price. In their whole SKU range since Kepler, NV was forced to use 1500mhz rated modules, while AMD could use 1250mhz rated ones because of the 50% bigger bus width. Now with Maxwell, they are forced to use 1750mhz rated vram.
