| Trumpstyle said: Okey let's just disagree. I just expect 7nm will bring about twice the TF compared to 16nm. And in my prediction I believe Sony will go similiar strategy they went with ps4 and ps4 pro. A console that has a pretty small box, consume 150w for the entire system and is pretty cheap to produce. So that means twice the compute units, 80. That is slightly higher clocked, let's say about 1050 mhz. This gives about 9,6 TF so a bit higher that I predicted. Edit: About xbox one die size, I don't know why it's relevent. Reason for the big die size was because microsoft went for Esram, without it the die size would probably be about 300mm2 |
You are still looking at it wrong. The two primary benefits from doing a fabrication shrink are cramming more transistors in a similarly sized space and improved thermal efficiency. The latter means that it would be possible to clock the chip higher before hitting a thermal ceiling or as seen in tech these days, make the casing smaller and use a smaller fan or none at all. You get these by default, without even trying.
So no, they wont double the compute cores in the XB1X (going from 40 to 80CU) then downclock it to 1050mhz. Thats counterproductive. At the very least it will run at the same clock or even higher. To not do so would mean that the console is prioritizing design over function. And thats just not how consoles are made. A 12TF GPU is pretty much they least you can expect on a 7nm process.
Oh, the PS4 OG die size was 328mm2..... and it didn't have EsRam. The reason these are relevant is that it should give you an idea what die size the are already willing to hit while still remaining thermally stable without using any extreme cooling solutions. That should set the basis of what to expect from the next gen hardware.

For PS5 sony will probably go for a similiar strategy as they did with Ps4 and Ps4 pro. A console in a small case, that's cheap to produce and the entire system pulls about 150W. This worked very well for them and they will probably stick to that strategy. For the Ps5 specs I got this: Cpu: Ryzen 8/8 cores (no extra threads) with a clock speed of 2,6ghz. This will pull about 15-20W and zen2 is the most likely architecture. Gpu: Navi 9,5 TF (upped the TF slightly from my last post). This should pull about 120W. Memory: 16 GB ram, will be gddr6 with 448 GB/s of memory bandwidth. Hard drive: 2 tb in memory storage. 140 mb/s read speed will be a laptop mechanical drive. Release time: 2019 with a 449$ price tag. |
- I have explained the GPU thing.
- If using GDDR6 and 16GB of it, unless for some strange reason sony decides to underclock the Ram, or even crazier insist on using a smaller bus than the standard 256-bit bus in an attempt to bottle neck it..... then the least you will get is 500GB/s of bandwidth. And thats lowballing it.

For the Xbox two specs, it was a bit harder to speculate. As Microsoft has already released Xbox one X which is pretty powerful and it will be difficult to release a much better console with a mainstream price in 2020. They will probably aim to keep the title "The most powerful console", this is what I got: Cpu: Ryzen 8/8 cores (no extra threads) with a clock speed of 3,2ghz. Will likely be zen2. Gpu: Navi architecture with 13 TF of performance. Memory: 12 GB gddr6 + 4gb ddr4. The operating system will run on the ddr4 ram and all the Gddr6 memory is for games. Microsoft will use a 384 bus width for increase memory bandwidth for an total 768 GB/s. (a bigger bus witdh is also a bit more expensive) Hard drive: Mechanical desktop hard drive, 2 TB with 200 mb/s read speed. Release time: 2020, 449$ price tag. This console will be slightly more expensive to produce compared to the ps5 as the entire system will probably pull about 180-190W, it will require a bigger console case and a bigger fan. |
Lol.... No. Look at it this way. This isn't another PS4pro to XB1X battle. Not a mid gen refresh. We are talking start of gen hardware here. There is not a chance in hell that MS lets sony release a new generation console a year earlier. Not a chance. Even with sony having won this gen, they would not let MS launch a year early either. And you really think sony will release in 2019, while bing the market leader and making a ton of money from the PS4 all the while launching a console that would have a GPU that is onna be as much as 3-4TF outpaced in as little as a year? Why?
Secondly, and more importantly..... if the PS4 and XB1 should have thought you anything, its that the next gen consoles will also be very similar in their hardware. More so next gen than they were this gen. Armed with that then you should know they are waiting for the exact same things before releasing their new hardware.
Looking at the XB1X, and the fact that its more similar design wise to the OG PS4 than it is to the OG XB1, it should be relatively easy guessing exactly what to expect from the next gen consoles.
