With navi 10 ? Don't think soCouldn't Gonzalo be the PS4 refresh? Qualification sample being out now would seem awfully early to me.
If it is 1800mhz navi 10 lite (48-56cu) then 11-12.9 tflops
"What took 15 seconds now takes less than one: 0.8 seconds, to be exact.They were explicitly stated that the PS5 had these. Nowhere does it say, "PS5 has an SSD." Everyone thinks it does when they read it, but when you really look at it, it doesn't and only implies heavily. But what's shown could be achieved by a cache. Might be a 64 GB flash cache between HDD and RAM. Might be a 1 TB SSD. Might be a 256 GB SSD and a large HDD. We don't know.
I'm fairly confident that's not what they meant.435.2 GB/s x 40 GFLOPs per GB/sec = 17.41 Tflops
435.2 GB/s x 50 GFLOPs per GB/sec = 21.76 Tflops
He may mean that PS5 RAM bandwidth can meet the requirement of a 17.41~21.76 Tflops GPU.
It's not that surprising since RTX 2080 only has 448GB/s bandwidth.
A the only one skeptical of this 1.8GHz number?..
Seems ridiculously high for a console....
Unless Navi is AMDs Maxwell (efficiency) and Pascal (clocks). The 1060 boosts to 1709 MHz while keeping the power draw relatively low.
Cerny refused to elaborate what the implementation is. He only implied it's faster than a pc ssd, and that it's a different implementation in terms of the full I/O path. The journalist interpreted this as an ssd."What took 15 seconds now takes less than one: 0.8 seconds, to be exact.
That’s just one consequence of an SSD"
I think the statement is very clear. The reporter does'really need to write a sentence such as "PS5 has an SSD". Since 0.8 sec loading time is consequence of an SSD, if PS5 doesn't have a SSD why 0.8 sec is the consequence of an SSD?
But I agree that the SSD solution is not mentioned, and we don't know if there is a HDD.

Eurogamer reported a rumor of 1TB SSD. It seems more reasonable than a cache because users can install several games completely into the 1TB SSD. If just using a small cache then the console needs to read huge data frequently from slow HDD, which causes slow loading when fast switching between different games.
Interesting part is that he asked Cerny why now, why the interview. He said they just sent out a lot of devkits, and they wanted to stay ahead of the leaks.Interview with the journalist that visited Sony, got the presentation from Cerny and written that PS5 article.
Sony called Wired, they were not provoked into the collaboration [for example, if Wired got early leaks from devs with devkits]. Sony just wanted to start the talk about the PS5.
Someone helpfully pointed out I wasn’t considering DDR4 bandwidth on top of HBM. That puts you in the 10.7 to 13.4TF realm.I try not to crosspost between forums, but I felt this was important to share. This is regarding the reddit rumor saying PS5 will have HBM2.
Another interesting point to make regarding this rumor is that TSMC actually consulted with Sony (among others) during the development of InFO_MS, which would make Sony familiar with it and probably in the back of their mind when developing consoles. I'd also like to point out that Sony is not a stranger to being inventive with memory. The Vita had a special packaging method in use to get very high bandwidth to the Vita's GPU.
Also, let's assume for a second there was a typo in the original rumor, because it doesn't quite make sense as it is. It says:
Which doesn't make sense. Typically when we talk about GPUs, we talk about GB/s per GF/TF, not the other way around. However, 40GB/s per GF would be a stupidly low number, so let's now assume they meant TF. We need a second part of the comment for future information
1.6Gbps per second would result in 409.6GB/s in a 2-stack config. 1.7Gbps bumps it to 435.2GB/s, which is competitive with 256-bit GDDR6 solutions. If we're now assuming the 40-50 GB/s per TF is valid, this gives us a range of 8.7TF to 10.875TF for PS5.
Finally, regarding my skepticism around HBM2 supply, some key things have happened since Samsung's comments about low capacity. SK Hynix and Micron have both entered the market in full force (after the latter abandoned HMC development). And the crypto market crashed. With DRAM and NAND markets easing up, that capacity has to shift somewhere.
Regarding HBM pricing, it's hard to know much it has eased over the past few years (we do have some Vega VII rumored costs for reference), but I think it may be possible to get it down to less than 50% more than GDDR6 per GB, perhaps even just 35% to 40% higher. When you consider that they just need 8GB instead of 16GB of GDDR6, their solution is extremely cost competitive. At that point, it becomes a lot more attractive. HBM is also done on contract pricing (i.e. not floating with market costs), so a big order from Sony locks that factor in and sets up a mutually beneficial relationship with that partner to help them build up their own capacity.
The only rumor around this giving me pause is the digitimes rumor that stated ASE will do the packaging. Other than that, a lot of this rumor makes sense the more I dig into it.
Also, I imagine if that PS4 rev mentioned is coming, it's definitely this Fall. Since it's a console rev, it may not get cracked open to confirm the 7nm EUV from Samsung part, but the timing makes so much sense with MS pushing costs down with the SAD model and the rumored E-revision of the device internals.
Finally, here's the rumor in its entirety for posterity:
And the extreme cynics could say the maximum 2.5 GB of data read could have already been loaded in the extra ram PS5 has since even the One X could.
What is Reasonable Ranges?
Reasonable speed of mechanical drive from 2013: 100 MB/s
Upper end of Mechanical drives from 2013: 150 MB/s
Extreme end of Mechanical drives even now: 200 MB/s
Interesting part is that he asked Cerny why now, why the interview. He said they just sent out a lot of devkits, and they wanted to stay ahead of the leaks.
Meaning we should get credible leaks now.
Well we know that power usage was a priority for them with Navi. Couldn't that chip be the rumoured top spec next gen Xbox?
