Laptops based on Ryzen 4000 Mobile will go on preorders today, however, it may take few weeks for them to be widely available. AMD releases more information on the architecture itself. AMD also confirmed Ryzen 9 4900H flagship CPU.

 

The Ryzen 4000 Mobile is based on Zen2 architecture, a refined version designed specifically for laptops. The new silicon is codenamed Renoir, it features with up to 8 graphics units and 8 processing cores (16 threads) — which also happen to be the specs of the Ryzen 9 4900H and Ryzen 7 4800U.

 

AMD claims 25% IPC gain over Ryzen 3000M, 20% lower SoC power, 2x higher power efficiency, and 5x faster state switching. But the integrated graphics received a substantial boost, all Renoir CPUs use 7nm Vega graphics.

 

The Renoir silicon is fabricated by TSMC in 7nm node, it features 9.8 billion transistors and the package is 25x25x1.38mm in size. This means that the package has twice as many transistors as Picasso while the die is 25% smaller.

 

 

 

About time AMD brought the fight to Intel on the laptop market. The power efficiency of the Zen architecture makes it a much bigger threat on laptops, compared to the desktop side of things where the 9900k can overclock its way to lead in gaming.

these arent leaks, iirc this is official information that the embargo was lifted for yesterday. 

Spoiler

 

in fact the headline in the article you quoted is:

Today AMD launches its high-performance Ryzen 4000H series and low-power Ryzen 4000U series for laptops. 

just fyi

Hardware Unboxed made a video on the topic yesterday, after spending a few weeks with AMD in February:

I'm surprised it hasn't been posted here before.

Interesting that U series are not getting much HT love and are mostly straight real cores.

Anandtech also has an in depth article into this as well

Now wait for the laptops to arrive.

Wow this is extremely good

I believe smt takes up a good but of power. Perhaps they decided to use some chips that would normally not meet the low power requirements to be a laptop chip and remove smt to allow for them to reach low enough power draw. I mean not all chips are going to be able to run at super low wattage so this could be a way around that whereas the H models aren't as constrained on low power draw requirements so it doesn't make sense to disable smt simply to decrease power draw.

These are quite a big improvement really, especially for mobile. Also seeing tighter control with OEM how they configure laptops is great.

6 out of 9 have SMT...

 

-edit-

nvm you said "U" specifically

2x higher power efficiency

If this is true it should make for some serious improvements on battery life. My current laptop has a 3700u and while performance is perfectly acceptable the battery life isn’t the greatest at around 5-6 hours using a 48 Wh battery and AMD’s balanced performance profile. I should mention that the laptop was purchased new with 8 gigs of RAM (I upgraded to 16 for $30 to take advantage of dual channel), 512 gig SSD, and it’s a 2-1 for $500, not bad. If pricing for these new CPU’s is similar it should be a real win for AMD.
