AMD Rembrandt specs revealed: powerful APUs that might fit into gaming handhelds like Steam Deck

The Ryzen 7 6800U is looking like a beast, even when compared to Steam Deck's Van Gogh:



https://www.techpowerup.com/img/ffNgnD4WY4gNqBrg.jpg



CPU
Van Gogh: 4-core Zen2 2.4-3.5GHz, 4MB L3
R7 6800U: 8-core Zen3 2.7-4.7GHz, 16MB L3

GPU
Van Gogh: RDNA2 8 CUs @ max 1.6GHz, 1.6TFLOPs, single shader engine / single shader array (?)
R7 6800U: RDNA2 12 CUs @ max 2.2GHz, 3.4 TFLOPs, dual shader engine / single shader array (?)

Memory:
Van Gogh: 128bit LPDDR5 5500MT/s, 88 GB/s
R7 6800U: 128bit LPDDR5 (up to) 6400MT/s, 102.4 GB/s


Power consumption:
Van Gogh: 5-15W
R7 6800U: 15-28W


Of course these new chips aren't made for the same power envelope as Steam Deck's Van Gogh, and at a similar 15W power consumption the 6800U might throttle so much it can't distance itself from Van Gogh.
However, we've seen a number of gaming PC handheld like the AYA Neo using 20W TDP on their SoCs and still getting over 2h of battery life.

Time for a PSP 3.
With Switch and Steamdeck, it shows they can play modern games downgraded for portable so Playstation no longer needs studios making Vita only games.

Plus the 4 shoulder button layout means it can play PS4/PS5 library downgraded.

Use sd card for memory and thats all the Vita issues dealt with.

Anyone who says it sold like shit, yeah true but so did N64, Gamecube and Wii U.
PSP has overall more sales that 3DS so it doesnt mean it will have Vita numbers.
It will have the library, controls and no memory card issues

Would only be able to run PS4 games, but yeah its possible now to make a PS4 tablet.

Unfortunately its like 5 years too late.
 
"Consumer Notebook Processor Lineup"

The U-series are always marketed towards thin&light laptops.

Just like AMD's 4000/5000U:
Product specifications for AMD’s Ryzen 4000 U-Series processors.




And Intel's Tiger Lake U:
Intel 11th Generation U series




Yet it's these were the CPUs being used in gaming handhelds like the AYA Neo, GPD Win 3, OneXPlayer and others.



The AYA Neo NEXT, being announced later today, is probably coming with these very same Rembrandt APUs. I doubt it's a coincidence that AYA decided to announce their next handheld gaming PC on the same day that AMD announces their next-gen APU.

PS Vita 2 ?

Gaffers please don't shatter my dream.
Well Komachi who first leaked the PS5 code names.


Has a list of AMD GPU generations.
[#小町戯言シリーズ] AMD GFX-ID : Which generation is the chip?

Looking through the list, you can see.
Microsoft XBSS/X SOC (GPU code is Lockhart/Scarlett)
ASIC ID : GFX10_2 = NAVI For SCBU.
: GFX1020 = ARDEN/ARDEN For Server = NAVI21LITE.
I'm thinking 'Arden for sever' is the XBSX.

Steam Deck APU
ASIC ID : GFX10_4 = NAVI For SCBU.
: GFX1040 = VANGOGH LITE = MERO (?).

Sony PS5 SOC (GPU code is Oberon)
ASIC ID : GFX10 = NAVI For SCBU.
: GFX1000 = ARIEL/OBERON = NAVI10LITE.
: GFX1001 = ARIEL/OBERON = NAVI10LITE.
: GFX100FFD = NAVI12LITE.
: GFX100X = NAVI14LITE.

Strangely enough, Sony has Navi 10, 10, 12 and 14 Lite.
So, my speculation is
Navi 10 Lite A0 = PS5 First Spin (Dev Kit?)
Navi 10 Lite B0 = PS5 Second Spin (Major Revision?)(Retail?)
Navi 12 Lite = PSVR 2?
Navi 14 Lite = PS Vita 2?

Is it just me, or are we being rationed advancements. All this time for a 4 core update in GPU tech? I was expecting 16 cores update over the old 8 cores to really push the APU technology ahead.

Yes, yes, its RDNA 2 blah blah. Even with the Perf.per.Watt uplift it still is a 19 core RDNA 1 (Just shy of 5500XT performance). Short of expectations given the time AMD has had.

APU gaming performance is often limited by memory bandwidth. Due to standardized motherboard designs, cost and power consumption they're almost always limited to 128bit of the latest DDR or LPDDR.
You don't get larger embedded GPUs because they'd be

Future APUs from AMD will probably have 3DVCache, but apparently those aren't coming in 2022 and maybe not 2023 either.

It is late, but can still happen.
Plus with Steamdeck playing the latest games, Im sure a PSP3 can play downgraded PS5 games like how Steamdeck is gonna play the newest games downgraded for 800p screen

Lol at getting Steam Deck fans' hopes up. That thing's locked in for a few years and already delayed twice.

I wish nvidia, intel were the good guys, and amd the bad ones. They simply can not make a decent gpu chip anymore [kind of dead since the 7970Ghz days].

eventually everyone is going to do the hybrid concept. Right now Nintendo is the only one that can afford to have outdated hardware in terms of specs, but years from now power/price is not going to be a problem. So don't worry PS fans, you will have your PSP, eventually.

No Rembrandt / Ryzen 7 6800U on the Neo NEXT, unfortunately.
It could be Van Gogh, i.e. using Steam Deck hardware.

Neo NEXT APU could be using Cyan Skillfish.
Zen2 + RDNA1 with Ray Tracing.

8 CPU Cores
12-18 CUs
1800-2000 GHz GPU clock
16 GB memory

Comparison of the other handhelds.

That would be cool. Maybe the XSS profile that exists for every game can help make this a reality on the xbox side. Performance would already be getting really close here, though GDDR6 memory to match XSS might be expensive power wise (what's the difference in draw between lpddr and GDDR6?).

It does not matter much how many cores the GPu has if the memory it accesses is too slow to feed them proprely.
PS Vita 2 ?

I would get that, if it could run PS4 games AS THEY ARE (or close enough)... 1080p IPS screen!!! can be attached to the PSVR headset... hmmm
 
.the thing is RDNA1/2 using 128bit can out perform GCN using 384bit.
I personally never understood how the bus width worked in graphics card. I remember at one point it was growing but then became smaller again or something. Guess architecture and memory speed made wide bus obsolete.

Yeah your right buses where getting bigger. I dont really understand them either i thought the higher bus = more and or faster RAM, but I think you're correct that other things that determine performance are at play.

I thought Cyan Skillfish was a prototype APU for the PS5, or what the PS5's SoC would have been if it launched in 2019 with a RDNA1 GPU.
Cyan Skillfish is recent and still being tested.
PS5 already finalized and has code name Ariel.

You can see Ariel and Cyan Skillfish are two different APUs. XBSS/X are both Arden.


Not to mention AMD has no fish code names for their custom SOCs for customers.
Van Gogh was said to be a cancelled. I can see Van Gogh being replaced with Cyan Skillfish.

Ariel = PS5
Arden = XBSS/X
Van Gogh Lite = Steam Deck

Green Sardine APU (Zen 2 + Vega)
Cyan Skillfish APU (Zen 2 + RDNA 1)
Yellow Carp APU (Zen 3 + RDNA 2)

That's not really the case. Yes RDNA architectures have better bandwidth usage, but all GPU architecture need good bandwidth to avoid limitation (and you'll see that directly when associated with high resolution). For example, RDNA2 PC GPU compensate their "lower" bandwidth compared to nvidia cards using big cache memory, but with these APU (and also with our gaming console) that's not the case.

Well im just repeating what I saw here


Where the 5500xt at 4tf sees similer performance to the higher bus 390

If this APU can run every Xbox One games, Microsoft should release a Xbox Series M, a portable machine.

If steamdeck can play future steam games on portable, maybe a new Xbox portable or PSP3 should be able to play Xboxseries and PS5 games downscaled on a 800p screen?

if AMD keeps this trajectory, Microsoft could actually release a Series S handheld in like 3 or 4 years.
the only question is... do they want to? they totally could do it tho seeing how powerful mobile AMD hardware already is today.
games wouldn't even need to be tailored to it if it can simply run the Series S versions of games

It is not like Nvidia isn't getting around the problem of memory on the mobile front. AMD is just being lazy and cheap.
3080 Ti Mobile
You're comparing top end dGPUs to iGPUs.

And AMD have tried going with some of the best memory at the time before. Each time it has turned out quite expensive for them. They tried HBM. They tried having really wide memory busses. Both are now not used in their consumer products.

Wait, so it IS about memory, or it IS NOT about memory? AMD throwing a Porche body on a Pinto engine with the Vega fiasco doesn't help your argument that they are constrained technologically.

Also that dGPU is on a laptop mainboard and at the 3080 Ti level of performance. Nvidia has to contend with a thermal envelope as well. You telling me AMD cannot squeeze out better performance than 12 cores on an APU?

Oh wait they did we just have to pay them for the desktop counterpart.
Radeon 6500XT

Which tells me they are rationing the APU market to pad their consumer desktop market with more options. You know since they can get away with throwing an extremely sub par desktop variant into the $200 market and still turn an insane profit.

Wow, you really are invested in Nvidia.

Sure, let's completely ignore that AMD (and Intel) have to cram their iGPUs onto the same die as the CPU. Let's ignore how little power iGPUs use. Let's ignore that the entire point of iGPUs is to be 'good enough for most people'. Let's ignore that dGPUs get their own section of devices for cooling (often with separate cooling these days). Let's ignore that the additional cost of APUs over CPUs is tiny compared to a dGPU. Do you know what there are for people who want to try and play at/near max settings? dGPUs.

Nvidia (and AMD, and in the future Intel) all have greater power and heat envelopes for their dGPUs as they aren't next to the CPU/APU.

You come across as very dishonest. You know that iGPUs and dGPUs are different things and why both continue to exist. Well, perhaps you don't and are an idiot, but I'll give you the benefit of the doubt and just call you obtuse.

I don't know what planet you are on, but I suggest you come back to Earth.

3DS sold more than PSP.

Sony won’t make a handheld because 1) It’s a crowded market with a clear leader (Nintendo). And 2) because all of their first party developers are working on PS5 or PSVR2 games. The Vita development bandwidth is now being used for VR. A business they can drive massive adoption in unlike the handheld market.
