Odd that it's reporting 4 logical cores there. I'd expect it to list 8.

Probably was changed due to testing. Shouldn't take it as something unless Valve says something

Maybe dropped SMT to emphasize low power and save die space? Full custom designs can do all sorts of wacky stuff compared to what we usually see.

Maybe it can be toggled on and off on boot as some games might work better with it off. It would be really weird for them to announce it with 8 logical cores and then not deliver that.

Removing SMT from the design would be such small savings in die space you'd be climbing a hill to convince anyone it's worth the layout effort.

It also doesn't save or cost power, it draws more power when it does more work.

Which is weird as SMT is exactly about power efficiency.

No, U-series often haven't HT. See 4500U.

Right, but their official spec sheet says 4c8t.

That's only with 4000 series which are based on Zen2 (like Van Gogh), all 5000U series have SMT including both Zen2 & Zen3.

As if we didn't know that already. What else would have 4 cores of Zen2 and RDNA2?

It’s missing an ear?

Wait a second


The Sega Neptune is real!

Pretty good leaking from MLID

It only has 1GB of VRAM? Hmm...

ID: h81e3xp

That's 1GB taken from the unified pool of 16GB of LPDDR5. I'd expect the OS dynamically resizes the amount taken depending on how much VRAM is currently required.

ID: h820gmu

Reserved, can not check my laptop now but if I remember well it can take up to 8GB if necessary, this should be the same.

Nanithefuck?! 4 logic cores? No SMT? VRAM 1GB? WHAT?!
