News Intel's Arrow Lake-S won't be an AI powerhouse — 13 TOPS NPU is only slightly better than Meteor Lake, much less than Lunar Lake

I'm also curious if the tiled architecture will mean the death of the F SKU or if Intel will release some without an IGP. I cannot imagine the packaging failure rates on just the IGP will be high enough on their own to make for a whole F SKU line.

Just saw this information mentioned by benchlife. They have listed some F-class SKUs.

Cannot verify the authenticity of this claim, but this is the first time we are seeing anyone mention an F-class SKU for the Core Ultra 2 "Arrow Lake" lineup though.

Could be true as well since this is coming directly from Benchlife sources.

Here is the Arrow Lake CPU architecture diagram. We have four main tiles on top of a base tile. CPU, SoC, GPU, and IOE Tile.

All four tiles feature a dedicated D2D "Die-To-Die" interconnect.

Interesting slide. Architecture layout seems similar to raptor Lake with some few minor changes in think in the CPU tile unless I'm mistaken.

I'm disappointed to see the security and AI complexes appear. If it's accurate, and it seems legit, that confirms the NPU and indicates all chips are likely getting that built in security core they added for MTL. This is definitely a desktop part as it's missing stuff that would be in the laptop SoC tile.

Wondering what the PCIe in the SoC tile is for unless that's the 4 PCIe 4.0 CPU lanes. I first thought maybe it was the DMI lanes, but they list DMI as well so I don't think it would be that.

It's not like RPL as that was still monolithic so the CPU cores were in the middle, but it is the same as MTL with changes to the SoC tile.

Ah yes, my bad. Not Raptor Lake but MTL instead. But this architecture is still monolithic.

I doubt this is an actual chipset based architecture design. All the 4 tiles seem to use a D2D interconnect and they seem to form a single monolithic package and don't seem to be separate from one another like actual chiplet designs.

No it's really not. Each of those 4 tiles are fabbed separately and packaged together using Foveros.

I'm guessing this has something to do with the MS Copilot PLUS AI PC certification though ? Not sure, but if these desktop chips indeed have an AI accelerator, then this would be the only guess that comes to my mind.

Maybe they are making this a compulsory feature in future lineup of both desktop and mobile chips. To hop on the AI bandwagon.
