Holy shit the IGPU on these nvidia cpus are going to absolutely shit on anything else.

I'm pretty excited for scaled down versions of these coming to handhelds. The efficiency and DLSS would bring the biggest hardware shake-up to that market.
The Switch 2 does wonders with that ultra low power Pascal. I'd love to see what a recent gen GPU architecture at 25W could do.
AuthoringInProgress@reddit
It may just match the Switch.
I'd love to be proven wrong, but one of the problems with this handheld space is that it's really difficult to see generational improvement, primarily because of memory bandwidth issues.
DDR5 over a typical memory bus cannot provide sufficient bandwidth to power modern iGPUs without massive performance hiccups. It's one of the big reasons the new AMD extreme chips aren't showing massive improvements over the previous generation options, they just don't have enough bandwidth. You need to run the memory faster or put it on a wider bus, both of which jack up power consumption and push the system out of the tdp range that makes handheld use viable.
The Switch 2 benefits from using customized silicon from the ground up, unlike the various laptop iGPUs converted to APUs AMD has been putting into handhelds, but even then memory bandwidth is likely going to constrain the system more and more as time goes on. Add to that the fact that silicon doesn't necessarily scale well at extremely low TDPs...
Now, most of the hardware within this power class are exclusively AMD powered, so it's plausible Nvidea gpus could circumvent the issue somewhat, but it's hard to say until we see actual products in the wild.

The ai max 395 strix halo was powered down on one of those tablets down to 12 watts. And it out performed most handhelds running a z1extreme at 15 watts by about 40%. The thing was it scaled really well so going from 15-25 watts on the handhelds normally achieved modest results on the strix halo chips it scaled very linearly. Double power you doubled framerate. At 24 watts it was using full system bus. So there is something to using a higher bus. A handheld with one of these chips can give you a true docked mode at 65 watts with impressive power and still run cool. Ayaneo Next 2 handheld is going to use one of these Apu. And AMD next gen strategy Medusa halo is widening the bus more to 384 bit which means you will see better bandwidth down low and better scalability while ramping it up. Once and starts incorporating RDNA 5 into it then we will see a major uplift in handhelds. All of AMD next gen soc for Sony and Microsoft will be using off the shelf PC soc. Think strix halo but with up to 70 CU. Strix is using 40 CU. Medusa Halo will be 48CU but still RDNA 3.5. by the time we see RDNA 5 I'm betting the bus on the top end SKU might even be 512. Remember they are looking for local AI models to run as good as possible. But AMD will have killer economies of scale cause consoles tablets laptops desktops handhelds will all run different power levels of the same architecture.

AMD extreme chips run on RDNA3 and there hasn't been an update nor will there be an update till 2027. Even Zen 6 APUs will still use RDNA3, that's 5 years of RDNA3.
Let's see what Intel X3 and Nvidia Blackwell can do in an soc form factor.
goldcakes@reddit
Reality is this segment is just not that big relatively to warrant the opportunity cost.
Vb_33@reddit
It's AMDs laptop (mobile) business. The laptop business is way bigger than desktop and desktop got RDNA4 not laptop.
Intel upgrades their GPUs mich quicker than AMD as does Nvidia, every new Nvidia gen is immediately put on laptops as well. This is very much an AMD problem.
Active-Quarter-4197@reddit
I thought the switch two used ampere
AssCrackBanditHunter@reddit
It even has some Lovelace features I think they mentioned but I'm not sure what features those are
AuthoringInProgress@reddit
Clock gating. Don't understand the science but it's basically a way of backporting some of Ada's power efficiency gains to Ampere.
PastaPandaSimon@reddit
It absolutely did. Brain fart around architecture names. Corrected. Thank you!
gizmosliptech@reddit
Have you not see the iGPU from AMD in 80W tablets in the Ryzen AI MAX+ 395? Can play most games on ultra at QHD settings already.
Shadow647@reddit
Only if we consider non-RT ultra to be actually "ultra", otherwise good luck
fuckthisnameshit@reddit
This is just wrong
gizmosliptech@reddit
Here’s a bench of game benchmarks of the igpu in this video if you don’t believe: https://youtube.com/live/RPUhAnPoHd0?feature=share
lintstah1337@reddit
For the low low price of $2000+
ProjectPhysX@reddit
This was known for long time already. It's basically an RTX 5070 as big iGPU, with 128GB unified memory.
Kryohi@reddit
Much lower bandwidth, lpddr5x will be a bottleneck even with the doubled bus width.
ProjectPhysX@reddit
Yes! Won't be particularly fast, and will be rather expensive. It's cool to have large memory capacity hardware options though.
Affectionate-Memory4@reddit
Looks to be a 10+10 CPU based on the 2 clusters. Based on the 4ghz clock I'm betting one of those clusters is Cortex X cores. No idea of the other, but some A7xx cores would make sense for E-cores on a beefy PC chip. The article claims X925 and A725 cores, and I believe that makes sense for the clocks and apparent size of this chip.
GPU is the same size as the 5070. I'm expecting performance close to the 5070tiM, as going a little wider and a little slower than that GPU's 5888 Cuda cores would be a bit more efficient. A reasonable compromise for a premium SoC.
I doubt it's literally a 5070 strapped in there, as in a GB205 die, but it could be the same configuration. 5x10 total with 1 TPC disabled. Could also be 4x12 fully-enabled, but that would drop it to 64 ROPs.
Lord_Muddbutter@reddit
A7x cores sound like a Nightmare
Affectionate-Memory4@reddit
I'm using 7xx as a stand in for anything that might start "A7". A725 like the GB10 or a new A730 for example. Not literally A7 cores.
Lord_Muddbutter@reddit
I should have known...
strawbitcherry@reddit
Such a replaceable liar... /jk
From-UoM@reddit
Its literally the GB10 chip from DGX Spark.
10 x925 cores + 10 A725 Cores.
It also has 48 SMs. You can count the SMs using the promo materials of the CPU.

The chip - https://youtu.be/kZRMshaNrSA?si=EQbQk_-uLomXp7p1
Its seams to have 4 GPCs. Each GPC has 6 TPCs each. Each TPC has 2 SMs each
4x6x2 = 48 SMs
Affectionate-Memory4@reddit
Oh awesome! I wasn't aware there were materials out for GB10 yet, or if there were changes for the N1X.
DerpSenpai@reddit
This could be a fake and just a Nvidia Spark
Affectionate-Memory4@reddit
It absolutely could. On the other hand, I don't see many reasons why Nvidia couldn't use GB10 as a WoA chip. If they already have the silicon made, it could make sense to get as many uses out of it as possible.
DerpSenpai@reddit
100%, as their flagship SKU
Marv18GOAT@reddit
Am I reading it wrong or does it say worse than 2050 and a couple lines down says competes or outperforms 5070?
AssCrackBanditHunter@reddit
I mean in that paragraph it literally gives a couple of reasons why it might be performing so poorly
col2thecore@reddit
Will they be selling the chip only?
Homerlncognito@reddit
Barebones PCs (or boards) at best.
RealisticMost@reddit
Really curious whether all is a missundedstanding and this is just the sparx ai computer or whatever but no Windows on ARM release.
Affectionate-Memory4@reddit
The specs of this exactly match GB10, so it's possible this test was run on a spark. But I don't see anything stopping them from doing a WoA product based on this chip.
wtallis@reddit
It was completely obvious all along that DGX Spark and the GB10 chip were part of something bigger. Releasing it first in the form of a low-volume Linux-based developer workstation then following up with mass-market products after getting Windows support up to an acceptable level is the strategy that makes the most sense.

VideoCardz just happened to find this:

all by themselves did they?
