It wasn't until October that AMD definitively gained outright single gpu performance.
You keep saying this over and over and it's incorrect. AMD definitively got the single-GPU performance crown in June 2012. Please go read 10-15 reviews when HD7970 Ghz launched. I am not going to repost them here again for the nth time. You can start with HD7970 Ghz reviews around June 21-22. Also, you conveniently ignored 1200mhz Sapphire TOXIC that trounced the fastest GTX680
a long time ago. With the latest drivers, AMD
extended the lead, not finally gained the lead. If you look at recent reviews and compare them to June 2012, the gap has actually widened in favour of HD7970Ghz, especially at 2560x1600 where the lead is now more than 10%. Additionally, it's impossible to even talk about GTX680 being on the same level as an HD7970Ghz ever since the Asus Matrix 7970 came out. I mean it's now
miles apart.
As far as those specs go, they are fake. There are major errors in that chart. Here are just a few:
1) HD8950 = 1050mhz x 2304 SP x 2 Ops = 4.84 Tflops SP vs. 4.5 in the chart.
2) Double precision specs are all wrong. HD8970 has 5.38 Tflops SP but they list DP as 1.6 Tflops. That's impossible since GCN has 1/4th DP. Even if you use 1/3rd it doesn't work.
3) HD8970 memory bandwidth = 6000mhz x 384-bit bus = 288GB/sec vs. 322GB/sec in the chart.
4) 140 TMUs for HD8950. That's impossible. Each CU is also equipped with 4 texture units & 64 Stream processors. To get 2304 SPs for HD8950, you need 36 CUs or 144 TMUs.
5) 50W power increase separates HD8870/8950/8970 despite a gigantic gap in specs between 8870 and 8950. This makes no sense since their clock speeds are so close yet the power consumption penalty is the same between each SKU step. This is not logical.
6) HD8990 with 375W of power? AMD couldn't get HD7990 out with 925mhz HD7970 x 2. Suddenly they are going to launch HD8970 x2 but a single HD8970 has an even higher TDP than an HD7970? Right...
I am not going to bother looking for more errors. These specs are rubbish. Some of those #s may be right but only by coincidence. The person who put that chart together doesn't understand how GCN architecture even works since even basic spec ratios don't align with how GCN is put together.
I would, however, probably not at all consider purchasing an AMD card if their financial situation continues it's course.
That makes a lot of sense considering you keep your GPUs for 3-5 years before upgrading. :thumbsup:
Your post would be a lot more genuine if you said you won't leave NV due to PhysX, TXAA, 3D vision, NV Inspector/driver preferences, or just brand loyalty. You realize who AMD's largest shareholder is? AMD can always tap
Mubadala for emergency funds. I guess from now on when we are buying trivial items that cost $300-400 we should do thorough due diligence on the company's balance sheet, income statement, build a DCF, consult industry and strategy experts on the company's going concern, double check its credit rating, perform a probability analysis on the chance of it failing in the next 1-5 years, etc. Sounds like a genuinely worthwhile analysis to hedge against a $400 GPU "investment" even though we'll probably upgrade in the next 2 years anyway to the next best thing for next gen games.
