Next Generation Hardware Speculation with a Technical Spin [pre E3 2019]

https://gematsu.com/2019/05/yakuza-...ory-is-finished-and-in-recording-ps5-comments

A lot of text that doesn't seem to say much, except maybe for continued PS4 support.

 

No. What I'm saying is that any type of customization on the GPU side for PS4 is more than likely straightforward or lite, nothing comparable to what needs to happen on the CPU and memory configuration side towards BC.

 

Remains to be seen exactly how much of Navi's earlier plans will be in this year's graphics cards, considering the architecture appeared with an early 2018 release window at some point.

 

You don't say...

CAFÉ is that you... lol

 

Ok, I have a different view than you do.
We was hoping navi would be a reasonable improvement over previous uarch, and now their rebranding it RDMA. I doubt things will just work with a couple lite tweaks.
Yet the CPU needed a magnitude more work.
If games was being recompiled for PS5 then I could half belief it.

It will definitely be interesting picking apart the differences.
Although may not be able to know if something only came about due to Sony, unless its not in Scarlett.

 

I read that as saying they finally have enough of an excess in CPU power that they can finally do more interesting things that aren't almost purely graphics or presentation related. So maybe we'll finally see AI in games catch up to what we had on the X360 again. IMO, the current generation (all platforms) took a backwards step compared to something like Halo: Reach, which IMO had some of the best AI ever in a game.

Alien Isolation hands down for me. Xenomorph was AI on steroids.

 

?
I thought they are teaching AMD how to do these things?

Lol that’s an impressive memory you have there. That totally would have flown under the radar for just about everyone here because we know there isn’t enough juice on Xbox.

 

Oh really? How could they fit 80 CUs? Radeon 7 is 330mm with 64 CU. A Zen chipset is ~70mm. Navi looks to have higher area usage per CU. So has are you going to fit all that in a 350mm APU on an even more expensive process.

 

OMG
Quotes like that were a gift to Misterxmedia. He served up kool-aid for two years with stuff like that. 15x Cloud power, APU + dGPU, embedded memory, and CUs waiting to be activated through firmware updates. I'm embarrassed to say that even I took a sip.

All that's required is the desire to believe what you're being told no matter how ridiculous it sounds and they've got you hooked.

 

I must quote this. It was a comment on that article, back in 2014, from a user named Jerusaelem:

"“The ‘Realtime Raytracing’ techniques will allow the Xbox One to finally generate the necessary 1.21 jiggawatts needed to propel the systems frame rate to a staggering 88fps, allowing both the Xbox One and it’s user to travel back in time to the year 1955!”, claims Microsoft’s studio boss/resident Peter Molyneux impersonator Phil Spencer in a follow up tweet. When asked where he came up with his concept in a phone interview later that day, Spencer replied, “I was hanging a clock in my bathroom after knocking back a fifth of Four Roses and a $2 gas station burrito when I slipped and hit my head on the toilet…when I came to, I had doodled a picture of the Xbox capacitor, which is what makes Realtime Raytracing possible! …also I drew a super cute gender swapped version of Bill Gates dressed up as Sailor Moon…they’re both on my DA page under the username qtPhilchanXB1 if anyone's interested. Constructive criticism only plz or your comments will be deleted."

 

Navis CUs will be smaller on the 32 SIMD wide config.Contrarly to popular believe CUs don't take most of the GPU die, they take around 40% a CU increase its not a linear area increase.
Radeon 7 has a lot of padding for yields and unneeded transistors for gaming

PS4 Pro was 325mm2 at 16nm and had 40 CUs with 4 disabled. Xbox One X had 44CUs and 4 disabled. when going from 16nm to 7nm, thats over a 2x increase and they could have put in 80CUs on the same size die.
For a deeper explanation i refer to @Proelite post

 

I am not sure how what he said in that tweet means or contradict anything. The tweet doesn't specify that said experiment with RT is on or will appear on X1. If anything this means the platform team has had RT in mind as a future technology with potential way back then. His recent statement in the 2018 vid was a direct statement on what they are working on with regards to the next generation of Xbox in which he name-checks framerate and RT as two things he has in mind for the next gen box.

 

Sure. But in 2014 we all ignored it. It wasn’t until DXR and We saw RTX demos in 2018 did RT mean anything to the entire gaming community.
It was an interesting hint to a larger idea that did eventually spawn. Just find it interesting he said his back in 2014.

 

Hmmm So perhaps while MS has moved onto Navi 20 (full Navi), PS5 is based on NAVI 10 architecture with GCN to facilitate easier BC. Sony does not have the software stack and software engineering capacity as MS, so perhaps they may have had to go with a more hardware based approach to backwards compatibility given GNM IS an arch specific api originally designed to go low level with Southern Island and GCN 1.0.

edited for typo

 

It does seem like Sony is going in between GPUs for the ps 5,( will probably be like a Navi 1.5 ) that’s not a bad thing to be honest.
I don’t believe there will be a big difference in the end between the two systems.
They still have similar constraints to contend with. These GPUs will be designed mostly for efficiency and grunt, they don’t have the space (like pc GPUs ) for a lot special sauce.

 

Thread dedicated to PS5 intermediate GPU is here: https://forum.beyond3d.com/threads/...0-ps5-navi-hybrid-xbox-navi-pure-spawn.61231/

 

r600 is ancient. Any idea why they’d want to support this?

BC for X360? Though X360 was using the r500, no? Maybe its closer enough to the R600.
