I know it has become a trend not to look at past console generations that much when speculating about this upcoming one and I get that, why would Sony and Microsoft be bound by what they did in the last 20+ years? We got mid-gen refreshes now which is unprecedented (I'd actually argue that the SEGA CD/N64 RAM pack are sort of a precedent) so people don't want to be bound by the rules of the past. Why not push past 200w tdp, hell why not push past 245w or 300w? What is keeping them from doing that?
I get that but with this recent speculation something is bugging me. An 11 TF or 13 TF RDNA GPU would immediately be AMD's top of the line card and there aren't any hints about such a GPU being released in the next few weeks/months putting the earliest release for such a GPU in late 2019 or early 2020 i.e. safe to say, less than a year before next gen consoles will be released.
How likely is it that AMD's top of the line card, or even one rung below, let's say the 2080 to their 2080 TI, how likely is it that such a card would end up in an affordable and at least somewhat power efficient next gen console less than a year later?
Yeah console manufacturers don't pay consumer prices, consoles tend to be sold at a loss, APUs are more power efficient than setups with discrete GPUs, 7nm+ will become a thing at some unknown point in the future and it will bring unknown benefits at unknown conditions - but that only gets you so far. Disregarding the past and just looking at this from a current standpoint, how likely is it for AMD's flagship high end GPU to end up in a console less than a year later?
There is unprecedented and there is wishful thinking.
There are a lot of precendents here that you seem to be conviniently ignoring.
1) You are ignoring the fact that the PS4, the PS4 Pro and the X1X were all based on the x800 GPUs in the AMD lineups. NOT the x700.
2) You are ignoring the fact that the Pro and the X1X launched the same year as their Polaris equivalents.
3) You are ignoring how both the Pro and X1X were made for profit consoles and yet contained MORE CUs than their polaris equivalents. the 480 and the 580.
In addition, You are ignoring the fact that last gen consoles were essentially designed as $399 consoles with the kinect costing MS an extra $75 that undoubtedly factored into MS's plans. Not to mention the ESRAM on the die to allow for 8GB DDR3 RAM for TV TV TV which made the die bigger and more expensive This time around they both have a $100 more to play with.
You also seem to have missed AMD's own plans for RDNA2 cards. They have specifically said that Hardware RT will be in RDNA 2, that RDNA2 will be 7nm+ cards and that they will release in 2020. We know the PS5 and Scarlett will have hardware RT. We know the 5700 does NOT have hardware RT. We know both Sony and MS used polaris cards that released the same year. Why is it so hard to swallow that the same will happen with RDNA2 cards on 7nm+? Especially now that they will be willing to take a loss unlike the mid gen refreshes which were designed to be sold for profit.
Just a few months ago, there were many people here looking at Vega cards and their TDP to rule out 10+ tflops GPUs. There were many on the 8 tflops bandwagon because it was wishful thinking to assume Vega 56 performance in a console. Now that the 5700 has been revealed, those same folks are now basing all their speculation on the new GPUs which again do not even support ray tracing. we simply should not be basing speculation on these new cards.
Lastly, if you do want to base your predictions on these new cards than you are getting a 7.9 tflops GPU in the next gen consoles. the 5700 is 7.9 tflops at 185w. Same as the 580 which was more or less equivalent to the GPU in the X1x. If we are to assume that 185w GPU is the max console makers can fit in a $499 console then logic dictates we must settle for a 7.9 tflops GPU. Are you seriously suggesting we should be expecting a 7.9 tflops GPU despite all the precedents and other info i posed above?
