Yeah, this is pretty ridiculous. How is any normal person supposed to know what they're actually buying? Buying the most important info in the third digit is just insane.


It's nonsensical. Exactly RE: most important info and the digit order. Hadn't read your comment in full before I replied to Uzzi, but I believe we see the same in this.

This is a case against it still - it's more difficult to garner the most basic information from this SKU system. The leading digit gives no information as to the (most important part of) the generation, which is the *one* thing your average lad might be interested in, if only instrumentally^1.

You did not at all read what I wrote, did you?

Your average consumer literally does not care about what processor is inside. It doesn't matter what you name them for that market of people, because those people won't recognise nor care about it either way. They don't read ANY of the numbers at all.

The number of people that read anything at all are a very small set of the consumer base. And they only make it to the i3/i5/i7/r3/r5/r7 names. not the rest of it. How many times have you seen people just call their CPU "an i7 processor" or something to that effect?

the Strategic Silicon Solutions group at AMD. I doubt they would bother with a mainline cost-optimized part.
SCBU->S3 is covering Sony, Microsoft, and Valve.
Seriously nice find about S3. That's rather fresh.

The leading digit gives no information as to the (most important part of) the generation
But exactly that has been the problem again and again, the leading digit too often factually is not the core generation anyway but the launch timing. For a current example, with Raptor Lake you have the 13th gen but how do you know whether a Raptor Lake or an Alder Lake die is being used in a particular chip? Through the model number alone you just can't. If you want to get Raptor Lake below the top chips the likelihood you actually get Alder Lake is very high.

Atari released Its last game in 2019, after that there is nothing, so what do you expect from their software side? Their console Atari VCS is just a retro box based on a 2C4T R1606G APU with 8gb Vram 32GB eMMC paired with Linux. You can play only 25 games as I counted on their webpage.
Are they really capable of using PHX2? I beg to differ.
2020+ games:
Pong Quest, Kombinera, Qomp, Recharged Series, Atari Mania, Atari 50th (Reimagined Series)...

These games are still pre-mobile to PC/console as in 2021:
"With the video game business looking to realign itself around the market for higher value-added
premium console and PC games, it was decided to discontinue the development of five free-to-
play games (RCT Story, Crystal Castles, Castles & Catapults, Ninja Golf, Atari Combat: Tank
Fury)." // There is actually more games than the above... one that should be shamed is Night Driver - Android/iOS.

Better Hardware -> Better Game selling price

Game mode example;
Raven2 3CU ~= Bristol Ridge 8CU
Phoenix2 2WGP ~= XeGen12 96EU/Vega7 8CU
There is a lot more frames given to 2d or extra fidelity given to 3d. Since, the DIY Developer (2022 OS - Beta Feature) games all look like Zeebo-era games. They definitely need new hardware if they want to breach the $25+ game market. Demakes/Port-downs will probably prefer RDNA3 graphics over current GCN. Also, makes the port to bigger consoles more simple: Atari Published game optimized for a hypothetical VCS2 can probably relatively seamlessly run on PS5/Xbox Series/Steamdeck. Atari published game profits are more important than own console exclusive victories.

For PC mode example; If they upgrade to Phoenix2+etc(ex: more RAM/NVMe) and price it at $299 for base, it wouldn't be far away from another modern cheapo minipc.
i31215u.png

Given Subor's Z+:
OS Option 1 (PC Mode): Windows 10
OS Option 2 (Console Mode): Windows 10 with Z+ Custom Interface

Makes sense to target the above because of the shocking "success" of this:
atariusbpcstick.png
Hybrid Option of Atari PC OS(first-party on NVMe instead of third-party on USB) and Atari Game OS.

Atari VCS problems:
1. Prior CEO
2. Crowdfunded
3. Bugs from FP5 having a common appearance.
4. Hardware is behind significantly, behind in game mode and pc mode.
5. Sourcing issues are becoming more prevalent.

Atari VCS2 having a PHX2 deal making sense:
1. New CEO
2. Not Crowdfunded, known market demand from the prior console.
3. Not being alone on PHX2, thus sourcing becomes easier.
4. Hardware is at least up to date to a standard.

On the "not being alone" part, example:
atarioddoneout.jpeg
One of these is not like the others... there is a much larger Gaming-focused Minipc market than in 2019. The userbase also thirsts for the bleeding-edge of cost-optimized.

To Steamdeck:
SteamDeck is already low-cost at $399 for what is being provided. So, it doesn't make any sense to come out with another product. That is in the same price domain as it.

The current SteamDeck refresh rumor covers the above instead:
6nm TSMC
Swaps the 64GB eMMC with a 128GB NVMe in the $399 spot.

The actual spot if Valve is going to target is a higher-end machine for their non-portable VR stuff. While using a later node to convert the steamdeck processor(4c/4wgp on N5/N3/N2/etc) into the SteamHead(Standalone VR Headset/No PC required) or whatever.

To re-iterate:
Valve/Microsoft/Sony/Nintendo => AMD's S3 division, because they make billions of revenue off their games/storefront. <== Prefers custom silicon.
Atari => Non-S3 division, because they make millions of revenue off their games/storefront. <== Can't afford custom silicon.

Hence, why Atari using a mainline FP8 from FP5 in a console deal would be more believable than Valve. They were the first announced customers for the cost-optimized Raven2 in a console setting. It would be the norm for the next cost-optimized processor Phoenix2 on the main, not the value socket to be selected for Atari VCS2.

This is sad, because then things will be difficult for those who DO CARE. Today I see several laptops advertised merely as Ryzen 5 or Core i7 etc.. without the specific model number. Some go a bit further and specify Ryzen 5 5000 series. But that's all still rather vague.

You didn't provide any reason why Steam couldn't use PHX2 instead of a custom chip. BTW the custom one Steam used is pretty much Van Gogh and that one was meant for Microsoft originally If I remember correctly, so It wasn't like they commissioned AMD to make them one, they used an existing one.

What I meant was a Steam Deck 2 Lite based on PHX2, which would replace Steam Deck at the $399 price point. Steam deck 2 would have a more powerful chip with more storage or even more RAM and higher resolution screen. I don't dare to say they will do It, but could do It, and that looks to me more realistic than a new Atari console with PHX2.

ATARI VCS:
AMD R1606G is basically Ryzen 3 3200U a 14nm Zen+ based 2C4T 2.6GHz(3.5GHz) with 3CU 1.2GHz Vega IGP
4-8GB RAM depending on model
32GB eMMC
Introduction price:
$299 (Onyx Base system without controllers)
$399(All-In system with 2 different controllers)
Those specs are so pathetically cheap, yet they dared to ask $299-399 for this!

Performance comparison:
3200U IGP -> 3CU*64SP*1.2GHz*2FLOPs => 461 GFLOPs
PHX2 IGP -> 4CU*64SP*2.4GHz*2FLOPs => 1229 GFLOPs
If I include the better architecture, then PHX2 IGP could be ~4-4.5x faster.
R15 ST 64bitR15 MT 64bitR20 STR20 MT
Ryzen 3 3200U130 (100%)353 (100%)318 (100%)727 (100%)
Ryzen 5 PRO 6650U234 (180%)1539(+436%)574 (181%)3564 (490%)
PHX2 CPU should be faster than 6650U.

4nm PHX2 based machine with more and costlier DDR5 RAM, bigger SSD would naturally cost more, so $299 for base without controllers is already pretty questionable and who would buy this console for that price without a controller?
You have better options like a more powerful Xbox with a Xbox controller for the base price or simply buy a Steam Deck for the price of console + controller with a way better software support.

You also didn't explain why Atari would even need to use PHX2 in Atari VCS2, when the games they produce simply don't need so much horsepower and can be played on Windows. Atari would need first those visually better games and only after them could have a reason for this console to exist or for buyers to want It.
Possibility of installing windows on It is not such a great selling point.

Current rumors suggest that Engineering Samples, for 35W designs, with 2600 MHz iGPU clock are around RX 570 in performance.

Isn't that like 50% faster? That seems like a stretch with no CU gain and only a 8% clock speed gain.

Not to mention no infinity cache and sumilar DRAM bandwidth. Driver updates in Linux suggest internal cache improvements with respect to RDNA2 and differences vs. desktop RDNA3 that point to a focus on improving capabilities relevant to its APU target, so it may surprise us, however, expecting RX570 level performance out of Phoenix without a significant hardware change vs. Rembrandt is overly optimistic.

Keep in mind, RX570 had 224GB/sec of VRAM bandwidth. Rembrandt was doing well to get 50GB/sec of read bandwidth out of its ddr5-4800 spec. Phoenix is supposedly only getting a modest bump to somewhere in the 5200-5600 range for ram, so maybe another 10% vram throughput is available. I don't care how good your memory efficiency is and your internal caching is, you're not making that up easily.

It is isn't why they couldn't use it, it was about why would they use it. If Valve got the custom Steamdeck processor without spending the silicon development cost good on them. However, if they want to do a Steamdeck 2 it would not be PHX2, but rather a custom solution with newer Zen_x/RDNA_y IP instead. Since, Valve is covered by the S3 Group at AMD. Every dollar saved on the first custom Steamdeck processor can be prepared for the second custom Steamdeck2 processor. Since, they can use customer feedback to make a better SoC -> leading to a better handheld or where ever.
4nm PHX2 based machine with more and costlier DDR5 RAM, bigger SSD would naturally cost more, so $299 for base without controllers is already pretty questionable and who would buy this console for that price without a controller?
People who are going to use it as a personal computer?

Atari VCS is currently $200 (Official Atari store) and to get the PC mode USB thing $40 (Also, Official Atari store). It is probably one of the current cheapest upgrade-able minipc's for Raven2. This is a lot cheaper than getting something from System76, purism, Think Penguin, other MiniPC+Linux vendors. As they can use game revenue to offset PC net profit loss.

It also gives them the benefit of just fitting under Apple, if they went MiniPC as well:
https://browser.geekbench.com/v5/cpu/18302986 <== Atari VCS
https://browser.geekbench.com/v5/cpu/19087977 <== Apple A16, (pointing towards Apple TV products but if they were actually aimed at the MiniPC market: TV has access to Apple Arcade. Which of course has a blend of phone-esque to console-esque games. Also, have to bring your own controller for Apple TV:Apple Arcade)

Atari upgrading to PHX2 and doing Streaming, Gaming, PC, etc stuff at least puts them on-par with Intel's cheapo minipcs and Apple's cheapo minipcs.
You also didn't explain why Atari would even need to use PHX2 in Atari VCS2, when the games they produce simply don't need so much horsepower and can be played on Windows. Atari would need first those visually better games and only after them could have a reason for this console to exist or for buyers to want It.
Games come after hardware releases. If there is going to be an improvement in figures of complexity with better 3D/2D framerates. A Phoenix2(RDNA3) VCS2 optimization would scale up or down from <-> Steamdeck(RDNA2) <-> XSS(RDNA2) <-> PS5(RDNA+) <-> XSX(RDNA2) <-> Gaming PC(RDNA/RDNA2/RDNA3), a lot easier than a VCS(Vega14-GCN) Raven2 optimization.

Atari VCS 1 (plagued by controversies, prior CEO) => Original launch window was Q4-2019 through Q1-2020, didn't become generally available till Q2-2021.
following industry <-- time between consoles -->
Atari VCS 2 (straight launch, sweeping VCS 1 under the rug, new CEO) => Launch window given +4 years = Q4-2023 through Q1-2024, bonus time till Q2-2025(avoiding this hopefully).
//New CEO -> ??? -> New Director of VCS* -> New Lead Architect of VCS*
* Not in known capacity, probably won't be till software is finished on VCS1. => No Crowdfunding.

The change away from mobile is to focus more on:
Nightdive's Remake/Remasters like System Shock Remake
Ziggurat's Remake/Remasters like Deadly Dozen Reloaded
But, for Atari games...

Convert an old game(that might not have been in 3D) into 3D. Then, first port is at least on one console and PC(before VCS2), then it is ported down to Atari VCS2(when it comes out). Visually beyond the scope of Haunted Houses in the Reimagined Series. It will take awhile before we see the actual games the PC/Console focus will actually lead to. As well as if Atari does use the PHX2 to extend their renewed VCS(translated: game console)/ST(translated: personal computer) ambitions.

Steamdeck: February 2022 +4 => February 2026, if Valve is following the industry. If not, they are more likely to follow Sony's rapid refresh cycles: 2020(7nm) -> 2021(7nm/lighter) -> 2022(6nm/lighter). In this, it is highly unlikely for Valve to swap out the Steamdeck processor for PHX2. Since, they would be going for a refresh with same exact specs and reduced power/heat like Oberon+: https://www.angstronomics.com/p/ps5-refresh-oberon-plus
With a February 2026 target it at least gives a window for porting down(Nintendo Sw1:20nm/Sw1+:16nm, same console different process type) or developing new(true SD2) on GAA-nodes.

Atari VCS has significant decay where the phone ports of 3D console games can run at 4K/1080p on Apple TV 4K, while it struggles at 720p~900p. Any extraneous work to make a port work would be mute if the hardware(aka using PHX2) was much closer to more modern hardware(2p+4e+>mid-speed iGPU).

Weighting benefits:
Steamdeck => Basically is already at Orin-Switch spec. Valve/Nintendo is already paired, no reason to switch to another chip of different spec than 4c/4wgp. There is no reason to downgrade to keep costs when valve highlights "great on deck" titles. Thus, anything lost on the hardware is given back by the cut of steam store. Which gives the opposite target, they will want an EVEN larger SoC than Phoenix1/Strix. Which will make them wait for mature GAA-nodes later in 2025+.
Atari VCS => Not paired with any current gen console, an upgrade is definitely desired. The minipc aspect is already way behind, Jasper Lake/Alder Lake-N/Alder Lake-M are pulling their cost-effective added-value weight. Thus, PHX2 has the highest benefit is for Atari not Valve. They also don't have billions of excess like Valve for a custom chip.

Distribution of sales:
Steamdeck1 + 64GB eMMC$399/$400Extreme minority of sales / Sold as loss
Steamdeck1 + 256GB NVMe$529/$530Minority of sales / Sold as profit
Steamdeck1 + 512GB NVMe$649/$650Majority of sales / Sold as profit
Given the above, the desire isn't to sale a worse model or a lite model. Since, the volume of sales by Gabe indicates preference of the best one.

A better SoC is preferred for big chunks of triple AAA:
Early millions $70 => $21 for every game license bought
Late millions $70 => $14 for every game license bought
It is up to developers/publishers selling on steam to have a SteamDeck mode(quality mode), since Valve isn't funding that. So a stronger, better SoC means less work for the developers/publishers who do decide to integrate a SteamDeck mode.

Steamdeck2 instead probably would prefer:
8c Zen4 (8p, 2p+6e, 4p+4e)
>8wgp RDNA3
$599 w/ 512 GB
$799 w/ 1 TB
$999 w/ 2 TB

Atari VCS Base (+ PC USB)$200 (+$40), less on salesMajority of sales / Sold as loss
Atari VCS All-in (+ PC USB)$300 (+$40), ' ' 'Minority of sales / Sold as loss
Given the table above, the desire appears more for a preference of a minipc rather than a game console. This is probably a symptom of launching the hardware with a barebone operating system, etc stuff.

Steamdeck was built off the SteamMachines/SteamOS. Atari VCS was a race track to get the hardware out. The current VCS plan is software(Games and getting the OS basic features: Dashboard, AtariLive(XboxLive clone), etc. features) with a shift to newer hardware(More likely to use PHX2).

With this timeline:
January 2022 => Atari new hardware was referenced
July 2022 => Atari has new hardware set in action
Time continues -> Atari finishes their development of the PC OS(usb stick) and Game OS(eMMC).
Time continues -> PHX2 AMD launch or reveal
Mid-2023/Q3-2023+ => Atari announces PHX2-based VCS and it is to use the hybrid-variant PC/Game OS on NVMe. Straight to release, no crowdfunding shenanigans/controversies/etc.

It is much more believable that Atari would use the PHX2 over Valve's Steamdeck successor using it.

What are people on about with "but same number of CUa as Rembrandt"... Hello? They're not the same architecture. 😅

I for one don't find it unrealistic to expect a similar IGP jump with Phoneix as from Cezanne to Rembrandt. Hell I think the RX 570 projection puts it at less than that. We'll know in a month anyway.

Pretty sure the MX570 already gets that level of performance at 96GB/s.

Also, why are we pretending the LPDDR5 specification doesn't exist? That's the one that actually matters the most for thin and light devices where the iGPU would be used.

speaking of mx570's, whats the deal with low power mobile dgpus like the mx series & 6600m from AMD? i don't recall ever seeing a laptop in the past few years which includes them- instead they all seem to have high power laptop versions of desktop gpu's like 3050, 3060, etc?

Just worth pointing out that N31 compared to the 6950XT is only 20% more CUs and is actually -5% on clock speed (at the stock 2.3GHz).

Context matters you know.

Yeah but AMD greatly increased the memory and infinity cache bandwidth with Navi 31, something Phoenix won't get the benefit of. And I thought the CU design on the IGP is an inferior version, reduced to save space.

And we haven't seen independent benchmarks of Navi 31 either.

I think 8C16T Phoenix could hit 4GHz all core in CB R15 with 45W TDP or 35W?

P.S. How is mobile vs desktop TDP calculated? Is It the same or mobile TDP is basically desktop PPT?

And none of that translates to RDNA3 IGPs being architecturally the same with RDNA2 tho.

The point is Phoenix vs Rembrandt/RDNA2, not vs RX 7900/RDNA3.

One big contention point I see is literally no one bringing up, is IGP power efficiency.

Ryzen 7 6800H (12CU, 2,2GHz) needed roughly 45-54W to sustain those IGP clocks across all workloads, Ryzen 9 6000 (2,4GHz) probably needs even more.

If Phoenix can sustain 2,6GHz+ clocks at 35W or less, then it already had a big leg up on Rembrandt. Irrespective of higher performance per CU, better DCC/end-to-end compression and support for faster DDR5 and LPDDR5X.

Here's a breakdown of what cache upgrades Phoenix/RDNA3 (GFX1103) is getting vs Rembrandt/RDNA2 and it's bigger N31 and N32 brothers:


They also talk about the new GFX1104 (PHX2) in a newer post. Use a translation machine if needed.

If 8C/16T 7700X clocks around 5.55 GHz at 65W TDP - at 35W TDP I think we can expect even 4.4-4.5 GHz all core boost.

Well Rembrandt 45W parts, like 6900HX, were actually 55W parts based on the power drawn for whole package.

P.S. With such temperatures on the CPU, for 65W TDP I think those CPUs are easily able to be passively cooled by something like Noctua NH-P1, or BeQuiet! Shadow Rock 3.

Let alone even lower wattage APU chips.
