AMD extends game-boosting 3D V-Cache to laptop CPUs for the first time

But it's not a waste of power if it's in a desktop?
I don't like laptops but why get upset about other people using something that's none of your business?

I'm always a fan of "lower power usage and higher efficiency" but especially in laptops. This sounds like a great use case for this caching tech.

Agreed, different use cases entirely. I have a desktop, but stopped upgrading it because I found myself playing in different areas of the home depending on the situation. Local game streaming solutions could work, but $250 for an XBox series S + 2 controllers (I know...ugh) was a much better proposition cost/performance wise.
If I had $4,000 to burn, I'd love to have this laptop and just shuffle it to whatever screen I happened to be near.

Meanwhile, my Windows Desktop is dismantled after a move and I'm doing all my gaming on either Apple Silicon Macs or a SteamDeck and I'm gaming far more, with more variety and higher-end games, than I used to.
I'm seriously considering just selling it to a friend (or family, I bet my Air Force JROTC nephew would love it and my flight sim peripherals) and going without a Windows desktop for the first time since 2008.
Edit: Let me add, that there's a surprising number of high end Apple Silicon native games now that'll run without turning on a fan while sipping power. At the worst the bottom of the case will get a little warm after a couple hours.

Wonder what the cooling situation will be like for this thing.
My dell G5155 (Ryzen 7 5800H + 3060m) gets toasty under full load (90C CPU temps) but that's within design limits.
Very interestingly, the keyboard surface is used as a heat sink area. If you try to run the laptop at even a moderate load with the lid closed, it will throttle HARD.
All that to say, Asus is gonna need to use every tool at its disposal to keep temps under control. But that's not new to them or the portable desktop space. Just always a constant challenge at the super high end.

I seem to recall that some gaming laptop vendors will pull in air from the keyboard opening and blow it out the back. So it's not that the keyboard is a heat sink, it's that it's part of the airflow design.

Hard no on the Asus. It has a heat exhaust port pointed directly at the right mouse hand. I've bought laptops like that and returned them since I'd need to wear an oven mitt while playing games.
Only interested if they exhaust out the back.
Note - I haven't bought a gaming desktop in over 15 years. I buy a new gaming laptop every 2-3 years.

It's even worse when it goes out the left side.....warms my beer up.

What an odd take. Power? If you want to rail against laptops, bring up the repairability with soldered on memory modules and integrated NVMe drives. Bring up the shortened life cycle and how more often they're designed to be e-waste when they reach end of life. They're not desktops. Evidently they're also not for you.
(Edited "landfill fodder" to "e-waste")

Damn, it used to be "gaming or laptop, pick one" but these days you can get a really good setup.

I love the framework 16 concept. It’s very close to all things to all people. I’m not in the market for a computer at that price (I’m much more a fan of off lease workstations and a used gpu, but that’s neither here nor there). I think there are great options when people pause for a bit and consider the options.

Sorry, but too many asshole are out there claiming to be autistic without an actual diagnosis by a professional (Elon Musk) just to excuse being an asshole. (Same with bipolar disorder, which I also have.)

It's not really too much of a issue for 15'/16'/17' modern gaming/workstation laptops....
It's been common for the last few years for top end gaming laptops to hit 300w+ total laptop power draw, with the GPU drawing between 120-175w, and CPU drawing 100w+...

Yeah, I was pretty boggled that the laptop in question, if not exactly thin and light, is quite svelte for a huge gaming laptop, yet has a 330W power brick and must be using most of it. The cooling system inside that must be legendary.

The biggest reason I don't like to spend that much money on laptops, especially not for gaming, is because they break. Apple's laptops tend to be pretty durable, but most I've owned on the Windows side of the fence have broken down relatively quickly, usually within a couple of years. And if you want to fix most laptops, it's usually staggeringly expensive, if you can get parts at all.
Desktops are less convenient, but very durable. The only typical wear items are keyboards, mice, and system fans, and all three are relatively cheap and easy to replace. You can make your own tradeoffs for price versus longevity, as well.
You can also upgrade a desktop; laptops that can do that are few and far between.

My current gaming laptop is literally 15 years old, I just use it to stream Game Pass and GeForce Now to my TV.

Thanks a lot Andrew for the article.
But what a s***ty naming system for these AMD CPUs.
I believe the two mentions of 7950HX and 7950HX3D in the article were meant as 7945HX and 7945HX3D respectively.
But I must admit I am a bit confused about these names ...

You’ve been here for that long and you still write comments like that one, huh? That’s wild. And not in the good way.

It would be really interesting if Framework did a motherboard with this CPU. Wouldn’t be for everyone, but there are certain applications (eg FPGA synthesis) where having lots of cache is a big advantage. Being just a motherboard it would be a single SKU rather than a whole range of laptops, so easier to manage. Maybe even a third party could do it. Not sure about thermals, but maybe scope for using the GPU bay for extra cooling?

I'm very interested whether they tested 32mb on each chiplet vs. 64mb on one, and what the results were. I guess it makes sense 64mb on one might be the winner, as games still don't seem like they make best use of lots of cores anyway, as turbo boost speeds usually seem to still be the winner compared to quantity of cores.
The built-in undervolting is interesting; I've started to advocate undervolting on Ryzen CPUs unless you have a big case with solid cooling, as a small drop of 0.05-0.1v can greatly reduce temperatures, while precision boost override gives you a lot of the speed back anyway.
I did this with a 5500 in my small form factor living room gaming PC, as on stock settings it could hit 85ºC with the stock cooler or an all-in-one liquid cooler, whereas a 0.1v undervolt keeps it around 60ºC maximum with the AIO cooler, with no noticeable performance difference in benchmarks (maybe 1 or 2%).
These days I don't really see much benefit to overclocking, whereas undervolting can give you much lower temperatures that can lead to better overall performance, especially in smaller cases. Plus it seems a lot easier to test for stability; if you undervolt and your system won't startup, you went too far, otherwise it seems to be fine, though you should still run at least one proper test to be sure.

Any chance you could point me at a beginner's guide to undervolting if you know of one please?
It's something I want to try, but I'm finding modern BIOSes horribly confusing and mobo manufacturer manuals quite unhelpful.

honestly its been that way since the Nvidia 970m video card, if not earlier. My first Alienware gaming laptop was nearly 15 years ago and it embarassed a lot of desktop users. Hell, it ran as much RAM as todays Apple silicon (or can they do more than 16GB now?)

Professional diagnoses aren't infallible.
Amateur diagnoses like yours are just garbage, and not worth the microsecond of "thought" you put into them.

So what's the point about being Autistic? I've been diagnosed as ADHD/OCD/BiPolar and Paranoid (is it paranoia when someone is actually out to get you?) along with being sociaopathic (Dalek's! Exterminate all Lifeforms!) More then likely the idiots have Aspergers Syndrome and feel that being an Asshole/Troll is the best thing to be. At least I'm an Ogre and tend to love playing with Trolls and Tangle Trees.

It's a 6.6 lb laptop lol
The now common vapor chambers has really brought the cooling of laptops forward by a huge amount since the old days of just heat pipes...
My friend has the lenovo legion i7 (intel+nvidia rtx 4080) that's only 5.85 lbs also got a 330w brick and it doesn't hit over 85C during gaming...
This is the cooling system of the older model of that laptop, but it's ridiculously big compared to my old ass 7+ lb 2007 dell inspiron 17 laptop lol...
Edit: of course reddit API fucks with linking their hosted pictures on other websites. Just pasted the link in...
