Guys some terrible news, I think navi sucks, look at this tweet:

Another note on AMD's GPU news. People have been asking if the 50% eff. gain is just arch, or arch + process. So I went over AMD's keynote for the specific words used: as presented, it's the latter. So arch + process gains = +50%. But we'll know for sure with a full tech briefing

It's 50% effiency gain with 7nm process and architectural improvements, just doing simple math we are absolutely not getting any crazy Teraflops numbers. The card AMD demoed is at best a 225watt gpu, probably 250watt and has about 10 Teraflops based on the 25% ipc gain. A $400 dollar console (PS5) need a gpu that pulls 120watt and a premium $500 console (Xbox anaconda) about 150-160watt.

Both console will almost certainly be below 10 Teraflops, based on the gonzalo codenamn showing PS5 having a 1,8ghz navi gpu it will likely just have 32CU's with 2-4 disabled CU's giving 6,4-6,9TF. Xbox anaconda will probably have 40CU's but 4 disable for yield improvements so 36CU's clocked at 1,9ghz is my guess and will result in a 8,7TF gpu.

Navi went from super-good to good to terrible. Look at this quote from Lisu Su at computex:

"And then, when you put that together, both the architecture – the design capability – as well as the process technology, we're seeing 1.5x or higher performance per watt capability on the new Navi products"

She mentions process technology!!!

That's good news though. If they have to use a crappy GPU anyways there is more room for that 1TB crazy fast SSD of yours!
