AMD's Mobile Ryzen 9 4900U Listed by Lenovo

A video posted by Notebook Italia may have spilled the beans on a whole new tier for AMD's mobile APUs. The video, which has since been taken down, showed Lenovo's upcoming Yoga Slim 14, which was listed in its specs list with an AMD Ryzen 9 4900U. Of course, the need for such an SKU is debatable: it's relatively unlikely AMD would bring more than 8 cores and 16 logical threads to the mobile landscape and its higher concern with autonomy rather than pure performance. Especially when one considers the particular Lenovo model involved: the Yoga lineup isn't so much associated with ultimate performance. However, there are desktop-replacement scenarios where users might definitely want to see a more than 8-core CPU powering their machine.

That said, this could simply be a higher clocked 8-core (the Ryzen 7 4800U does feature a base 1.8 GHz/up to 4.2 GHz boost clocks, so there's room for improvement). The Yoga Slim 14 where the Ryzen 9 4900U was listed does only weigh 1.1 Kg and has a quoted 11 hour battery life on the 4K screen option (versus 14 hours on the FHD version). We'll just have to wait and see, with our thinking hats on. A typo is possible, but hard to make in both the physical specs list on the pictures, and on the official Lenovo website. The fact that the original video has since been edited with the specs list obscured definitely means something's afoot. This could also be another AMD bullet for the mobile market, where it has achieved its biggest share growth in recent times.

This. THIS. THIS WOULD BE PERFECT IF:

1. Thunderbolt 3 certification (not just DisplayPort USB-C Alternate Mode)
2. Paired with a full CU 5500M (or 5600M if it's possible to fit in a 14" chassis), like in the 16" MacBook Pro
3. 75 Hz to 144 Hz FullHD IPS panel
4. USB-C PD charging up to 100W (20V 5A)

Wouldn’t make much sense for an OEM machine to run a CPU that has not been announced. What would be the point of the secrecy, and wouldn’t AMD want to promote its own products? I guess it could be announced when this laptop launches.

Kudos for that Lenovo, and shame on you for limiting the screen options and reserving 4k UHD only to crashed blue.

It's a pretty beefy monolothic SOC if it includes eight cores, the usual IO functionality and a capable iGPU.

They actually aren’t very big—basically the chiplet X2. And the chiplets are already pretty small.

Ever been to a trade show? Judging by your response, I guess the answer is now. Always a lot of unannounced stuff at trade shows, if you pay attention. So this is far from a first.

But a higher model CPU? I get all the odd lesser products, but I would have to think that all the journalists at trade shows would pick up on a higher-than-announced mobile Ryzen out there.

Could be planned, to build up hype for unknown/unannounced products that the general public doesn't know about yet. It's a valid marketing tactic for companies.

I welcome a potential 4900U that can take on the six-core i7-10710U.

Odd lesser products? You mean like unannounced CPU SKUs? Happens almost every year at Computex.
I've spotted a lot of things over the years, usually at companies that you don't expect to have samples of those parts, as they're not exactly tier one.
It's also the fun part of shows like Computex, spot the unannounced products...
A lot of the time, things like this are hidden in plain sight.
Things like this for example.

Who even cares for 144hz on a thin and light laptop. A 4k OLED or MiniLED screen is far more appealing

Obviously I care since I would like it paired with a 5500M or 5600M which is capable of running some games with appropriate settings. Hi-DPI at 4K (regardless of panel) seems more useless due to the screen size. I would agree with you on 17.3" desktop replacements though.

Give me that full HD IPS panel first that doesn't cost an arm & a leg, in this part of the world :shadedshu:

I thought so too until I got an HP Spectre with OLED 4k. Hard going back now. Before it I had a ROG zephyrus which honestly sounds like the kind of laptop you are looking for. A 120hz screen with mid tier gaming specs. You won't get a 5600m on a form factor like this Lenovo here

Also, it would be perfect if Lenovo stopped doing crappy stuff like this, supposedly they have... but who knows

2015... I own two Lenovo laptops made in 2018-2019 and after clean Windows install bloatware was not installed.
If it's at the BIOS level of data mining, etc - you would never know it was there. The 2015 one was at the BIOS level. So....

It's like that stupid ASUS Service Crate (or whatever it's called) that you can disable in the UEFI. I'm not sure if that can be done in Lenovos. I have the 2019 Flex 14 with 3700U and it didn't really have any bloatware. On the Dell G5, there's an option in the BIOS to disable the "service drivers", but I would install it anyway because you can control the laptop fans and battery charge through SupportAssist.

Yea that isn't a typo. There isn't a Ryzen 9 nor is there a 4900U spec. The chance of 2 typos is pretty much next to none.

Do you think IF will reach 2400MHz this generation Seronx? Micron just introduced 6400MHz with DDR5 specification. This will be a big contest for whom exploits it first.

I'm hoping it's a 12 core. Then I would be very tempted. If it's just another 8 core, I'll wait for the next gen and pcie 4.

Well guess what, there's apparently a 4900H on the way too, unless that's also a typo :D
A retailer has posted preliminary listings for some upcoming Asus laptops. They do not contain product images, however, based on their model numbers and listed specs, they are clearly destined for the high-end gaming markets. For example, one of them appears to be for a Ryzen 9 4900H-powered Zephyrus G14.

Why?

12 cores is neat, but a 12 core 15 watt chip? for anything multithreaded, it would suck chode compared to the 8 core, constantly TDP limited, unable to boost at all. zen 2 isnt THAT power efficient.
