Baseless Next Generation Rumors with no Technical Merits [post E3 2019, pre GDC 2020] [XBSX, PS5]

[Shortbread]

You really should go read the latest patents from Cerny, it shows their approach is more advanced than a software emulation and forcing high level access. There are no limitations or requirements for next gen hardware from that perspective, other than gating different sections, and adding low level translation layers. With this they can do boost modes and nearly 100% perfect compatibility, and practically cycle-exact fallback modes, which software emulation cannot do. If they succeed with this plan, they end up with the best of both worlds. It defintely requires a massive expertise to pull it off, from hardware and software alike.

Reading those documents destroys the narrative. Dumpster diving in pastebin nonsense and console warrior twitter ramblings are their safe-space.

People kept saying this before ps4p launched (sony stuck with old gcn version cause they suck at BC), and it ended up with a gpu with a more advanced feature set than MS who launched a year later.

The 4Pro was a frankenstein GPU, it was 2 of the PS4 GPUs with minor additional instructions added.

Nothing of that speaks to software advancements in virtualization or abstraction layers for the hardware, which is what was mentioned. So it seems Sony leans on hardware compatibility while MS leans on software.



Minor Additional Instructions, mostly surrounding 16-bit math instructions with conversion to and from, and some gradients:

• Scalar ALU Operations
  • 16-bit Pack Operations
• Vector ALU Operations
  • 16-bit Floating Point Operations: Arithmetic, Packed Arithmetic, Comparison, Field Access, Rounding, Transcendental
    
  • 16-bit Integer Operations: Arithmetic, Packed Arithmetic, Comparison, Shift, Packed Shift
  • 32-bit Bitwise Logical, Shift, Rotate, Bitfield
• Scalar Memory Operations
  • Real-time Global Timestamp Read Operation
• Vector Memory Operations
  • Buffer Access with Format Conversion
  • Image Access without Sampling
  • Image Access with Sampling

Yeah these regression tests for Oberon BC1 and BC2 are really extensive when it comes every GPU HW feature. Sony's solution for PS5 is tied to the hardware.

1. Having BC means Sony will have a chance to lock in 10's of millions of users who spent money on PS4 games over the last 6-7 years. Definetly more than just 7-8%. Would be a massive selling point.

My point was never that PS5 wouldn't have BC... but that PS5 hardware choices aren't solely wrapped around it.

2. Not really fanboy nonsense.

It is. I'm really not in the mood on posting certain statements of such BS as evidence.

but that PS5 hardware choices aren't solely wrapped around it.

Not solely, no-one said that, but it has been in their design from the beginning one can imagine.

 

[MrFox]

There's a misunderstanding about what a hypervisor and hal can and cannot do.

MS also have to design the hardware based on BC goals. They cannot just put an nvidia and ARM in there.

Reading those documents destroys the narrative. Dumpster diving in pastebin nonsense and console warrior twitter ramblings are their safe-space.

Unveiling is probably next month, we'll get more answers and less crazy rumors.

 

[PSman1700]

Unveiling is probably next month

Is that confirmed?

 

[BRiT]

Is that confirmed?

There is the Sony CES thang on 2020-01-06.

And someone on ResetEra mentioned a February 2020 reveal, but can't recall exact details.

 

[Deleted member 7537]

No way it is revealed at CES. Sony will have a separate event for their most important consumer product.

 

[Proelite]

It's not only hypervisor it's also HAL (Hardware Abstraction Layer) in the form of DirectX.

Yep. The Xbox BC team really delivered for MS this generation and the next. They're better setup for the future because of the BC teams work.

 

[MrFox]

Is that confirmed?

No I was just going by the history of Sony unveiling in february, with price at E3, for a holiday launch.

 

[mpg1]

This is the downside of "coding to the metal"..

 

[PSman1700]

There is the Sony CES thang on 2020-01-06.

And someone on ResetEra mentioned a February 2020 reveal, but can't recall exact details.

So a wild guess, not a confirmation it's about PS5.

 

[PSman1700]

Sony has nothing more important then play station?

 

[mpg1]

So a wild guess, not a confirmation it's about PS5.

Speculation based on the blue backdrop.

 

[BRiT]

So a wild guess, not a confirmation it's about PS5.

I think it was Klee that said Feb 2020 over at Era. So if you trust his hardware info you could trust his event timeline info too.

 

[iroboto]

Camera sensors come to mind.

 

[PSman1700]

I think it was Klee that said Feb 2020 over at Era. So if you trust his hardware info you could trust his event timeline info too.

Which is nothing. Feb is a guess, a good guess perhaps as it fits the timeline.

 

[X-AleX]

Which is nothing. Feb is a guess, a good guess perhaps as it fits the timeline.

It's a guess based on the PS4 reveal, which happened in February 2013.

 

[PSman1700]

Yes, nothing to do with Klee being god.
