Yeah there still is contradictory info about the GPU uArch of Renoir. Two things off the bat that for me make it highly unlikely Gonzalo/Flute is a AMD APU are 1, I believe they are 4c8t and 2, surely won't have 40CUs Gonzalo/Flute seem to have? Pretty sure there are some other things that point away from it too.

AMD bin their chips, so Renoir performance probably ranges from poor to good/great. I very much doubt it's a single product configuration unlike Intel chips.

At the top end of Renoir's performance curve I could see it reaching the levels of Gonzalo/Flute - which I don't believe are next-gen console chips but ymmv.

I just simply believe it highly unlikely AMD go from the top desktop APU of the 3400G with 4c8t Zen+ and 11 CU Vega that launched 3 weeks ago to a 8c16t Zen 2 and 40CU Navi less than 6 months later.

Even with the cut down cache 8 cores seems top end for APU.. and why was there a single APU score, when we should expected multiple Renoir skus .. no this seems like a custom sample, not part of a product range

But AMD haven't gone with 8 cores in a APU so far. Probably because they need as much die space for the GPU? And just how big would a 8 core Zen 2/40 CU Navi APU be? 12nm 3400G is already 210mm^2.

It just seems so highly unlikely!

Depending of who you ask: Gonzolo believers or heretics

Gonzalo believers have less base than my dead momma, is ridiculous, no thx :c

The heretics are just working with theoric facts, but nothing directly from employees, not from Sony, amd, or whatever.

Sigh ;;

Raven Ridge used D or M indicators in it's OPN. G is for something more specific. Like a Subor or PS5.

G is for gaming.

AMD offer embedded solutions for casino and gaming machines that support up to 4k and 36 CUs.

Applications include
  • Digital Casino Gaming
  • Amusement with prizes
  • Skill based gaming
  • Pachinko/Pachislot systems
  • Video/Lottery systems
  • Arcade/Panyu Gaming
HongFu Lottery platform anyone? ;)

Of course much easier if we continue to believe that all this underpowered AMD stuff is PS5, right?

Much more here

Aaaaand you are wrong.

Polaris does not have FP16. Vega has FP16.

Since PS4 Pro has FP16, it cant be Polaris based.

Except it is.
Every today GPU has FP16... hell even older GPUs from 20 years (Nvidia FX even run FP16 twice faster than FP32 like Vega).

What Vega has and Polaris not is RPM... Rapid Package Math... in simple terms Vega runs FP16 twice faster than FP32... so twice faster than Polaris.

PS4 Pro chip is Polaris based with some features from Vega but the main parts are Polaris.

Missed up a bit? The entirety of the leak is wrong Lol.
It's full of obvious nonsense even for back then (like the 32bit CPU, no-HDD, and 'opengl gpu') mixed with some bits he must have overheard from a real source (like the codenames, 8 cores, and even the early 4 core part (which was not a Jaguar afaik)).
Which seems to be a running theme for early leaks - people get one or two pieces of random info and pad it out with their own fantasies.

If you're managing publicity/secrecy and want to avoid leaks the standard way to do this is create so much noise that even if the correct data comes out no-one can see it for the noise.

This old leak actually fits the pattern - it takes the correct code name(s) and attaches nonsense info to them - so if anyone leaks later with the same (correct) code names - it looks like they're just an internet fantasist who is shitposting ....

This is what makes me think the 5700 in the consoles may be able to support RT.

So someone from Era cought one super interesting tidbit.

Flute and Gonzalo are both Shakespear characters lol that cannot be coincidence!

Ok so I checked for Ariel! Its Shakespear character as well holy shit :eek:

Ariel is a spirit who appears in William Shakespeare's play The Tempest

https://en.m.wikipedia.org/wiki/Ariel_(The_Tempest)

Francis Flute is a character in William Shakespeare's A Midsummer Night's Dream

https://en.m.wikipedia.org/wiki/Francis_Flute


Gonzalo (/ˈɡɒnzəloʊ/ GON-zə-loh) is a fictional character in William Shakespeare's The Tempest.

https://en.m.wikipedia.org/wiki/Gonzalo_(The_Tempest)

OMFG

As a person who studied practically all of Shakespeare's plays and sonnets, I'm personally embarrassed that I didn't decipher this myself.

mmmm Project Quantum revived?

Renoir is laptop APU with low/mid Vega chip.
Renoir was originally listed as Vega but more recently it is being shown as Navi.
R600 is right, commercial AMD APU won't have nowhere the grunt of Navi 10, maaaaaybe Navi 14 and even that its probably too much

AMD commercial APUs are just CPUs with integrated graphics that go inside CPU sockets
An APU with a 5700 class GPU with its own dedicated memory (gddr6/hbm) needs a custom board to properly feed it, so gonzalo/flute (if real) is semi custom. That said a company like Alienware might be interested in such design for a economic performance gaming box or laptop. Or Subor
This is what makes me think the 5700 in the consoles may be able to support RT.
Unlike RPM, RT its not simple addition, it requires the GPU pipeline be designed around it.

Funny how on ree they are pushing the narrative that 1700x performance is somehow good news :messenger_tears_of_joy::messenger_poop:

Interesting post on by3d
Let me inject some data here. While pricing per wafer is hard to come by, and likely depends a bit on the specific chip (number of exposures) and of course volumes, current pricing seems to be just over $5000/wafer for TSMC 16/12nm and ”just under $10000/wafer” (I’d ballpark it at $8/9000 or so for a 10000 wafer order) for TSMC 7nm. Again, at this point in time, as cost per wafer typically drops at a somewhat exponential rate after introduction. Also if you come in with a large order (say 300000 wafers) and stretched over time, that should affect pricing downwards as well.

Then you need to estimate the number of dies per wafer, and for a ballpark estimation you can use a calculator such as this.
Yeilds will tend to improve over time, and you would also design a big console chip with redundancy, for instance only using 7 out of 8 cores, or 44 out of 48 CUs or some such to mitigate the impact of defects.

I used his estimates to calculate the costs of a ~390mm2 die
LXTIUDR.png
Defective Dies: 43
Partial dies: 8
Good Dies: 94
Recovered Dies by Redundancy (50%): 21
Total Good Dies: 115

$9000/wafer, cost per die = 9000 / 115 = $78.3

Granted this is the cost straight from the fab without accounting for R&D, packaging, AMDs cut etc, lets add $50 and round it up to $130 per APU.
Also worth pointing out consoles manufacturers will place orders north of 100k wafers for the first year alone, so better better pricing per wafer

This looks good. I tried before based on 75% yield for 128mm2 and a $10,000 wafer cost. That gives a hell on earth yield for 400mm2 of 43% (yours works out at ~79%), and a cost of $165 per die after correcting for partial dies ..

Design costs have been estimated ~$300million (or $3 if you sell 100million..) I'd expect packaging to be sub $10, though there are additional costs like shipping etc all minimal. 100% mark up on production cost in normal, though Sony should be able to get way less.

Was defect density a guess, or are there up to date figures ?

PS5 with dedicated ray-tracing chip/chiplet? I'm surely daydreaming, but here's my crazy theory: if that rumor turns out to be true then maybe Microsoft and Sony won't focus on rasterization performance that much and instead they will spend their budget on raytracing. That would explain Gozalo being only equivalent to a 5700/XT. Imagine having a big dedicated chip for fullscene raytracing. With consoles being designed to last about 7 years, focusing on RT kinda makes sense. I bet many games in some years will switch from using rasterization/Hybrid RT.

Another point brought up in the video is that raytracing requires a lot of memory. Maybe next-gen consoles will have a lot of memory after all (or maybe that's why they'll probably be using the SSD as virtual RAM).

What do you guys think?

Makes no sense from a performance or economic perspective
Its a shitty theory, sorry to be so blunt but it has no merit
How come chiplets are advantage, when it's about CPUs, but suddenly not the right thing, when it is about APUs?

Pros:
1) yields
2) heat spread
3) flexibility (piecemeal upgradable etc)

Cons:
1) harder to package, perhaps?
2) linked via Infinity Fabric, instead directly... (but what does CPU have to share with GPU anyhow? Do they have shared cache in APUs?)

RT cores might simply be to small to warrant a separate die.

But we're talking about x86-64, which is 16 years old. :)
Yes, something FORCED, when we hit 4Gb wall and were left with only ugly memory addressing solutions.
AMD64 (Intel, of course, had to give it a different name, but that's what it is, is mostly "how could I slightly change things, to support 64 bits"..
