WTF??

Ryzen 9 with LPDDR RAM?
And how they want to cool that processor with such ridiculous thin chasis and no ventilation entry?

On paper it has Ryzen 9. In reality it will have Ryzen 3.

Lenovo go f*** yourself with such trash design.

What on earth are you on about? Let's do this point by point:

-Dell is able to cool a 25W+ CPU in their XPS 13. This is a larger 14" laptop, so with a little effort 45W should be perfectly doable. It doesn't have a dGPU, keeping the total heat output down.

-LPDDR4x has higher bandwidth than DDR4. The memory controllers in Renoir are able to operate as 2 64-bit channels of DDR4, up to 3200 MT/s, or four 32-bit channels of LPDDR4x, up to 4266MT/s. The latter has significantly higher bandwidth, uses less power, but has slightly higher latency, tops out at 32GB capacity maximum (theoretical, not for this design) and only comes in soldered-on form factors. LPDDR4x should make for a very noticeable performance increase for GPU-bound workloads.

Apparently the idiot "WTF lenovo 45545" has been banned and the post removed. But let's try to answer the guy anyway. If he had only bothered to check the reviews of this unit (also called the Yoga 14S 2021 in China) with the maintenance hatch cover removed, the internals show a twin fan twin heat pipe cooling solution. Compared to the crappy Intel/Nvidia non-pro Lenovo Yoga Slim 7 version, this Pro version with AMD only needs to cool one single die. That is how Lenovo is able to coax such insane performance levels out of this 8C16T beast of an AMD 4800H/4900H!

So much angst about nothing!

Still not available in Canada months after the announcement. So disappointed in Lenovo.

I have been eyeing this while still waiting for a premium Ryzen laptop with - USB 4, 2-in-1 functionality with low-latency pen, base Nvidia dGPU, RAM sockets, better webcam in this day&age, and maybe, just possibly a bright OLED 120Hz display.

Nevertheless 16:10, QHD, 90Hz display and Ryzen H SoC in a thin and light Ultrabook are great moves from Lenovo, and honestly super commendable for setting up a high bar for 2021. Well done.

Finally arriving on PSREF in Asia and Australia
MT=82LA

Quite disappointed with that 400nits glossy screen... It's going to be limiting for mobile people.

nb: they've already released in Intel version with Tiger Lake i believe....

They haven't released the intel version...They promised the AMD for August-September and still nothing.

Where is this laptop? Still no signs of it.

Every time I think Lenovo can't get more idiotic, they step up and show they can. Seriously, what's the point in developing a naming scheme if you're not going to stick with it and are just going to start throwing various names that used to mean something on whatever random things they feel like. Yoga is supposed to mean convertible, yet lately they've been releasing several "Yoga" computers that are not!al laptops. Seriously Lenovo, get your heads out of your @$$3$.

Look like only the intel variant will have the 90hz screen... Why? Are you saying the Ryzen 4900h doesn't have enough power to use it ?

Also, there's no thunderbolt 3 on this one.
Fun fact: Lenovo put TB3 on the Yoga 7, and not on the Yoga 7 pro. I will not even try to find a logic anymore...

Lenovo please, make this and the ideapad Renoir laptops available with 32GB RAM.

The 8GB is just silly with such powerful APU's, Any Ryzen 7 APU should come with 16GB & 32GB RAM options, while Ryzen 5 & 3 come with 8GB and 16GB options.

Damn, why no 32 GB RAM option ? It would have been perfect for me  :(

Lenovo Yoga Slim 7i Pro will have up to 32gb ram, it might be using tigerlake as the press release says it uses next gen intel. it might be pretty good, who knows tho lol.

I don't understand why there's always a raft of "ugh, 16GB" comments on these types of devices. It's not a workstation. 16GB of RAM is enough for the vast majority of users - if you need more, you need a workstation laptop.

I kindly disagree. By your logic why would have this slim, small and very portable device should have Ryzen 9 4900H processor in the first place ? As you said, majority of users wouldn't need that kind of processing power anyway. And if they did, they should purchase a workstation laptop.

You can always make use of more RAM (atleast on Linux, don't know about Windows, but I assume it will work similarly), because OS will cache filesystem to the RAM and so you get faster access to the filesystem. It's much, much easier and cheaper to increase RAM than to put stronger CPU inside laptop. When you insert stronger CPU, you need more power, so you need design better cooling, which is hard to achieve in small, slim and lightweight device. So that's the thing I do not get - why Lenovo puts AMD's top laptop CPU and don't back it up with more RAM.

Hm... well if anyone is still waiting on the 4800u review, a Chinese youtube video seems to show cinebench r15 starting at 1600 points and dropping immediatey, then stable around 1490 points after 30 minutes.

The leaked notebookcheck chart shows it starting around 1590 and dropping to 1480.

In comparison, the notebookcheck test of the T14s 4750u pro starts at 1350 and dropping to 1300.

This actually looks like a solid use of Renoir - LPDDR4X in combination with the 45W Ryzen variants should provide better sustained CPU and GPU performance than Whisky/Comet Lake + MX150/250/330, in a smaller board area than that combination and with better thermals. Add a decent screen in a solid chassis and you ought to have a bit of a winner!

Yeah 16GB only is getting pretty dated especially in a laptop as fast as this.

I'd say 16GB is almost a non starter these days if the ram is non upgradable... my work laptop has 40GB in it (32GB + the 8GB i was ordered with).
