I wouldn't be keen on trusting the words of someone with far less journalistic caliber than a rumor mongerer like Usman Pirzada, let alone someone like, say, Linus Sebastian. All of which would be perfectly happy to blast any tech rumor out of a megaphone if they laid their hands on it (since, of course, journalists aren't bound by non-disclosure agreements).

Several people are vouching for him and saying he is super reliable, they know him from Neogaf time.

HDD+SSD combo just won't work and I gave up on it a long time ago. Just look at the spiderman gameplay demo, how much data would require in the SSD and the Vram for spiderman to fly around in jet-speed in the entire city? How much for a next-gen game? What happens when someone loads up spiderman when there is 0 data in the SSD, you somehow gonna load 40-50GB of data from a slow mechanical laptop drive into the SSD and the Vram, it just won't work.

They do work... Trying using a PC with a 32GB Sandisk SSD Readycache cache drive+5400rpm HDD verses just a 5400rpm HDD. It's a night and day difference, it really is.

It takes a few rounds for the data to be loaded in, if the console recognizes that you launch more often other titles, it will preference that games data onto the Solid State Drive untill such a time that is no longer the case.

There will also be various small reads for OS/Background tasks that can be loaded from the SSD constantly too which can expedite various operations.

This post got much longer than I thought but short version (remember these specs are based on what Kleegamefan said):

XBOX: 8Core zen2 cpu clocked at 2,8-3,2 GHz, 52CU's GPU clocked at 1600Mhz (10,6TF), 1TB SSD, 12-14GB Vram 560 GB/s memory speed (10GB available for games).

PS5: 8Core zen2 cpu clocked at 3,2 GHz, 52CU's GPU clocked at 1800Mhz (11,9TF), 1TB SSD, 16GB Vram 512-576 GB/s memory speed.

Clockspeed based on the FLUTE/Gonzalo leak and 4 reports that PS5 has higher TF number.

The CPU being 8-core is a single Zen2 CCX, I have been asserting that next-gen will use a single CCX before we even knew what Zen 2 was going to be due to cost-reasons... If AMD was less ambitious with Zen 2 and went with a 6-core CCX, then these consoles would have likely had 6-core chips.

GPU clocks will likely be driven pretty hard I think, it worked well for the Xbox One X and allowed for a smaller, cheaper chip, so that line of thinking will probably continue.

Taking few rounds to load the data into to the SSD is the problem, the point with the SSD is to create new gameplay experiences not only to reduce loading times. Game developers won't be able to rely that enough or correct data is in the SSD when it's needed.

The spiderman video sony showed is a good example, how is spiderman suppose to able fly around the entire city in that speed when there is 0 data in the SSD, players will be hit with a massive long loading time to make it work.

Zen2 still contains 4 core per CCX "On these chiplets are two groups of four-cores arranged in a ‘core complex’, or CCX, which contains those four cores and a set of L3 cache – the L3 cache is doubled for Zen 2 over Zen 1." - Anandtech

I'm not sure why that is important but 8core per CCX wouldn't make much sense, 1CCX will be used for laptops and 8cores would just be to much.

About the clockspeed, I reduced it for PS5 to 1600mhz+, 1,8ghz is just to much for 52CU's even with 7nm+, also now I think I know why Sony is going with clamshell design, 16Gbps+ pins with 2GB Vram won't be ready for massproduction in time but 1GB Vram will be.
