12-21% IPC increase for MTL over RPL? Locuza and Semianalysis already did a great die shot analysis of MTL. It seems there were few changes to the core, so doesn't that make this IPC prediction completely impossible?Thanks. Was on mobile at the time. Didn't want to scrub through a video. Or give it a view, tbh. And quality is plenty fine.
So I'll just give my take item by item.
MTL:
ARL:
- Socket - No clue. I thought MTL/ARL would use LGA
18001700 (Edit: Typo?), but I also knew they would not be platform compatible with ADL/RPL. Could see this being true, but little difference either way. Though a new socket typically hurts motherboard prices.
- IPC - Bull. Maybe bigger than Raptor Lake, but 12-21%? Nah, he's just making stuff up.
- Clock speed regressions - Probably bull. Maybe they'll lose 100-200MHz or so, but large enough to compare to ICL? Nah. I fully expect the node shrink to make up any regression from arch/design, and personally guess that clocks will ultimately be higher between comparable SKUs.
- VPU - sure
- 2+8, 6+8 - sure, 8+16 - no
- RPL/MTL volume split - Not sure, but certainly suspicious.
- Timing - Sounds reasonable enough.
- 8+32 on 20A - Think so?
- LNC IPC - I'm thinking comparable-ish to Golden Cove's gains. Expecting >>GLC gains (like his previous "at least 30%" claim) is just nonsense. But make no mistake, LNC is probably the most important evolution of Core since its inception. Much better in a whole host of ways.
- Lion Cove is not Royal. Royal is Royal. How hard is this to understand? Clearly no clue what he's talking about.
- Skymont - We're in for a treat with this one.
- Timing - Sounds reasonable enough.
In short, I think all the "new", important details range from suspect to nonsensical, and the rest just reiterating well established rumors.
I've seen MLID be proved wrong many times before, but never as soon as he made the prediction 😆
