If it had not been Kinect in the package with the first Xbox, now you certainly would not say so, I mean to say that the Xbox one would be a lot stronger console than PS 4, which Anaconda will certainly be, whether you like it or not
But the Xbox One was a $100 more for the Kinect alone from what we heard. Take that away, that's a $100 less and now at $399 like PS4, with its specs still lower at 1.3tf vs PS4's 1.8tf.

MS simply weren't thinking straight back then.

Penello, guys.

As in Penis.
I like Panello. Gives me this funny image he has a Pan for a head.
 
PS5's not quite 8TF. It's more like 7.8TF.

That's according to a guy I overheard talking about it in the pub tonight. His mate's cousin's step brother once delivered some sandwiches to the SCEE offices back in 2015, and he heard them say 7.8TF as they came out of a board meeting. Can't get more accurate than that.

Although to be fair he did get the sandwich orders all mixed up, so there's always the possibility he was wrong.
 
If they do I really wish Other OS would come back, those cards are like $6999. We could get back to a console being a standout general compute per dollar machine like the Air Force PS3 cluster lol.
But we all know that OtherOS did nothing to increase their PSN profits. :)

Even MS doesn't allow you to install a regular Windows OS and run regular x86/Win32 apps on X1X. It's not a coincidence.

If original game relies on 4gb/sec. Then for 500mb/sec you'll need 8x the buffer.
Let's say console has 16gb ram. Then you need 128gb/ram to just keep up with the speed. You maybe able to rearrange data (will hit performance) and get to 64gb. But not realistically less than that.
Of course it's all hypothetical. But 8x speed difference in file mapping will be brutal.
PCs will use DDR4 buffer to achieve the same result. So initial load times will be higher to load the DDR4 buffer but its smooth sailing after that.
Let's say consoles have 20GB GDDR6 available for games
PCs 8GB-16GB VRAM and 32GB DDR4

On PC you can double consoles memory 40GB (VRAM + DDR4) vs 20GB
You have a 20GB memory buffer advantage on PC which can be used to stream assets on the fly.

I know I know...But a hardware nerd and data scientist wants what he wants...

If this does use an SSG configuration, it would be the cheapest way to get it by like, 14x. 14x just considering the card, not the whole rest of the computer around it.

Are they going to port XBOX 360 games like Halo, Gears etc. to an ARM-based console and still hit 720p 30 fps?

Would be cool if true, but I think streaming is far more likely (even home streaming from XBOX to Switch would be more than welcome, IF Nintendo would allow it).

Not sure bro. The thought just popped in my head while sitting on the can.

Even the XB1X is HDMI 2.1 compatible (although I'm not sure it ever got certified), so the next gen should absolutely be.



Indeed. It's funny how some people underestimate Microsofts ability to say a whole lot of words without saying anything with substance. If Phil wanted to say, that it was going to be the most powerful console, that's what he'd say. He specifically used the term "set the benchmark" to be able to turn that phrase into whatever he wants it to be.
They updated the Xbox one x to have hdmi 2.1 features. Not 2.1 itself. There isn't a cert for it. Tho it does use ALLM and Vrr.

Oh. Forgot about it. So first PC will be crippled by not enough vram and then by low streaming caps.
Pretty bad.
You cannot seriously compare high bandwidth vram with low bandwidth ram and you can never just add one to another.
Reminder: in directx vram is managed by system ram at all times. No more unmanaged buffers for you.

If consoles have 20GB available to games, only 10-12GB will be used as vram the rest will be used as system ram
You don't need as much bandwidth for CPU.

PCs will still have a 20GB buffer advantage to load streaming assets
8GB VRAM should be fine the first 2 years, i think 16GB VRAM GPUs will become the norm next gen.

It's all high bandwidth ram. The target usage doesn't matter. Both CPU and GPU can access same pages in AMD arch. All of it is VRAM for that purpose.
You have seen separate pools last gen only because the main platform in all the multiplatform games was D3D.

CPU has imbedded RAM?

So it's 78TF then.
MONSTER.

System ram is used by CPU, and VRAM by the GPU even on an unified pool
CPU does not benefit from crazy super fast bandwidth like GPU does.

uh?

Nope. The whole point of unified RAM is to access same pages by both GPU and CPU without needless copying. For example: CPU is setting up motion vectors according to controls pressed by user. And then GPU blends animation using that data. I.e. one slow write by cpu: vector update. Multiple fast reads for gpu for various animation tasks. Same ram page.

  1. CPU - 3.4ghz 12core Zen2
  2. GPU - AMD "Arcturus" 14.336tflops (80CUs) + L4 1GB @1.3TB/s
  3. RAM - 28gb gddr6 (4gb for OS) @672GB/s
  4. STORAGE - 500GB SSD NVMe @6GB/s cache + 1TB HDD

  5. "Secret sauce"

  6. MS AI + RT HW core (colab with Intel)
14TF arcturus + HW RT in a console😂😂, not even MS fanboys have so vivid imagination. But I need to say if MS will really pull it off, I will be willing to spend even 700$ on that console.

Who is this guy in the youtube? I can’t wait for the E3 conference so these silly videos stop.

I know the GPU can access system ram but it does so through a much slower memory bus so it doesn't make a difference how fast system ram is
Im assuming what's partitioned as system ram by devs can only be accessed by the GPU through the super onion bus. If someone more knowledgeable can confirm or deny this i would appreciate it.

Yea, 14TF isn’t happening lol.
Im personally betting somewhere in between 12-13TF
But at this point it woulnt surprise me 14TF

SSD and RT were far bigger surprises that i would had bet anything on it not happening yet it did.

There is no hard partitioning it defeats the whole purpose of unified memory.
The difference is CC (cache coherent) or no-CC access.
CC is needed for more complicated scenarios, where you need to do computations with CPU and GPU on the same blocks. But it doesn't mean that once block is accessed through CC bus it cannot be accessed through non-CC one.

The main benefit of unified pool is flexibility when it comes to assigning system ram and vram as opposed to hard limits
I admit i don't know if whats partitioned as system ram can be accessed by the GPU through the fast bus, if you are certain I'll take your word for it

Anyways i think 8GB VRAM cards will be fine for the first two years of crossgen ports, for next gen only games 16GB VRAM GPUs will be set for the whole gen.

I've done some calculations assuming next gen consoles have 20GB available for games and a 4GB/s SSD:
8GBVRAM/32GB DDR4 PCs would need a 2GB/s SSD

So you were right a 500MB/s SSD wouldn't be enough even accounting for the extra memory buffer, but i don't know if such scenario where you need constant non stop 4GB/s+ streaming will be common
Im inclined to believe a 20GB buffer would be enough for current gameplay till the next loading screen. We'll see i guess, especially interested to see how Sony exclusives exploit it.

It would be a shame if 3rd party games are (ironically) held back by PCs

It all depends on the exact spec.
But if very high throughput flash controller (>3gb/sec) will be there PCs will have a hard time keeping up.
Of course it can be crippled by the interface (ssd block device will be awful, direct ram mapping will be enormously fast and low latency).
And if ps5 will resemble ps2: relatively small ram size but huge wide buses, PCs may not even be targeted (as it was in the ps2 days).

IIRC, this dude made a video around the time that osiris talked about the PS5. Pretty sure this dude has no insider info.
Yea, it seems like he's just guessing and doesn't really know what the fuck he's talking about. And his voice makes me cringe.
