Hmm I don't know where you gotten geforce 1080 ti performance from never seen that anywhere, I think Navi mid-range cards will be between geforce 2060 and vega 56. The latest rumors had Navi mid-range at geforce 2070 but it was likely all fake though.
Right now I believe PS5 will launch Spring 2020 at 399$ with 3,2ghz zen 2 cpu that has 8 core and 16 threads, Navi at 9TF likely vega 56 performance, 12 GB Gddr6 Ram on a 192-bit bus and 1TB NVMe SSD drive.
And you probably will be wrong on just about everything you said there with exception to the CPU.
Damn there is s much wrong in that post......
Lowest to expect will be 10TF. First off we know nothing about Navi other than its a more efficient architecture than Vega or Polaris(whats in the PS4pro/XB1X). So if we take the CU cunt of the XB1X, do nothing but put it in a 7nm chip, we will be able t clock that GPU t as much as 1.8Ghz. Being that its really small. That alone gives you 9TF+.
But lets say they can some how throw in more CUs (which should go without saying really) And lets say for some reason they can't double the CU count (PS4 to PS4pro) or Triple the CU count (XB1 to XB1X) But instead only can add about 50% more CUs to whats in an XB1X (so 40 to 60 CUs). Now since the chip is bigger, say they only clock the GPU as high as 1.35GHz. You end up with a 10TF+ GPU.
And this is not taking any new improvements a new GPU architecture will no doubt bring
Not a chance it has the same amount f RAM that the XB1X that was released in 2017 had.
Further more you also aren't taking the inherent benefits of GDDR6 into account. Each GDDR6 package has twice the capacity of GDDR5 (16Gb vs 8Gb) while also being twice as fast. This means that if sony goes with a board layout similar to the PS4/PS4pro the least they can end up with is 16GB or GDDR6 ram. If they go with one similar to the XB1X, then they end up with 24GB of RAM.
Oh..... and definitely not on a 192bit bus.... dont even know where you pulled that from. Minimum 256bit bus and max 384bit bus.
Just forget that NvME drive.
It may be an M.2 drive. And as such an SSD but definitely not NVME class.
I'm glad you finding so much wrong with my post but let me explain. About the GPU.
First a 40CU (xbox one X SOC) clocked at 1800mhz on 7nm transistors will probably pull about 200w we need to get that number down to 100-120W. Looking at Vega for both 14nm/7nm, the chinese console and amds own apu with just 11CU at 210mm2 die I just can't get the math to support a gpu that has more than 9TF. Just looking at Vega VII with 338mm2 die at 7nm having just 60CU we can conclude it's very unlikely we will see more than 60CU on PS5. And based on towshardware vega 56 review on how much power this card pull at varies clock-speed my conclusion is that PS5 will have about 56CU clocked at 1200-1300 MHZ. Which is actually pretty close to what you wrote.
RAM and Storage:
There's two reason I believe we will see 12 GB ram and not the common-sense prediction of 16 or 24 GB of ram. The first is prices of GDDR6 seems a good amount higher than Gddr5 and second there won't be any need for more Ram anyways because PS5 will use AMDs High-bandwidth cache controller (HBCC) which will make the ram usage much more efficient.
Because of HBCC next-gen consoles will go 1TB NVME ssd drives which is needed to use HBCC, now I seen some people thinking the price to high, but right now looking at Newegg 1TB NVMe cost between 155-180$ (I'm assuming Sony buys this stuff half the retail price) and those are high quality NVMe SSDs (intel 660p, HP EX920 and Corsair Force MP300). Prices are also predicted to drop between 20-50% this year and will likely drop a good amount during next-gen because of very high competition making 1TB NVMe ssd drive an excellent choice.
