Is there some hardware limitation of AMD Ryzen laptop processors that prevents a high-res display?

Every time I see one of these laptops (like the recent HP linux laptop, etc), I think they look really interesting except that I wish they had a higher res display - I've not seen any Ryzen laptop with what I'd call a premium display - something high DPI.

This laptop is a refresh based on the Tong Fang PF5NU1G chassis. Tuxedo just announced their version, the Pulse 15 Gen2 that has a WQHD 2560x1440 165Hz 350 nit display: https://www.reddit.com/r/tuxedocomputers/comments/vrb1me/tux...

There's no limitation for Ryzen itself, it's largely up to the ODM/OEM to decide. For example, Lenovo and Asus have multiple QHD/4K options for Ryzen 5000 and 6000 series (iGPU-only) laptops (just do a search for Yogas, Thinkpads, Zenbook, Vivobook, etc).

Note, certain designs might have display limitations. A couple years ago, for the 1st gen PF5NU1G, Schenker tried to get a 4K OLED panel to run, but failed due to PCON compatibility and then sourcing/logistics issues: https://www.reddit.com/r/XMG_gg/comments/izg598/no_4koled_pa...

I've actually found it quite hard to find Ryzen 6000 laptops with just an iGPU. RDNA2 would be perfect for me, you lose the weight and cooling issues that come with a dGPU but still have enough graphical performance to play some games.

I've scanned through the Lenovo site as an example and I can't find anything AMD with a display larger than 1920x1080 (at least on the UK site)...

How's the keyboard on the Pulse 2 from someone who might be very partial to loud, clickety, far travel, mechanical keyboards?

How does Linux do with the high refresh rate display? Does it destroy battery life like I imagine?

It's probably a limitation of the company they source the laptops from (Clevo?) :-)

The recently announced Tuxedo Pulse 2 [0] has a 1440p display; and the teased Starlabs Starfighter [1] is expected to come with a 4K display. Both are AMD laptops.

I didn't even see the Gen2 release. I own the Gen1 after much consideration (and very nice community management from Tom over at the XMG Subreddit). I got it in December of 2021 for about 600 Euros. (Great Deal).

I know I am very susceptible to "the new shiny" and already have the itch to go for the Gen2 since it really brings some amazing improvements to the table. Mainly more external displays. The rest is nice to have (wouldn't have needed >60Hz panel to be honest). Oh and the Gen1 USB-C charging only works with a subset of all available USB-C chargers. Probably some kind of incompatibility with the IC on the motherboard. [1]

If you're thinking about getting it, I can (at least for Gen1) vouch for it.

To clarify: Tuxedocomputers is a subsidiary(?) of XMG/Schenker. Their "Pulse 15" is equivalent to Schenker's "Via 15 Pro".

The Tuxedo Pulse 2 looks amazing. They really addressed all of the complaints we had (purchased at the beginning of the year for our company).

I still have minor nitpicks with it, but those pale in comparison with the display port upgrade they did.

jeffalyanak · 4 years ago
It's not a hardware limitation, but many vendors are still using AMD only in their budget SKUs and using Intel in their flagships.

Since the AMD SKUs are aimed at a different price-point, they generally don't have higher end display options.

Can you please explain what use hi DPI displays have in general? I bought one and it was almost nothing but disappointment except viewing photos. For me it concludes as purely wasted computational (and electrical) power.
speedgoose · 4 years ago
The text looks a lot nicer, without subpixel rendering which can also save computational power.

pivo · 4 years ago
As others have said, smooth, crisp font rendering. I’ve been using high DPI displays for almost 10 years now and would never consider going back. Using a 1440 monitor, say, feels to me like using a machine with a floppy disk: an anachronism.

My wife though swears she cannot tell the difference and doesn’t care which she uses. This boggles my mind and is actually a bit frustrating to me, but that’s my problem.

So, I’m interested in if you can tell the difference but don’t care or if it’s something else.

I’ve always used a Mac though, maybe that’s the difference? Never seen Linux/Windows in 4K.

minimaul · 4 years ago
For me, it's all about text. I spend my whole day staring at text in some form - email, code, etc. A good high DPI display creates a much better text shape for the same physical size text on screen (and doesn't have as much of an issue with trying to snap vertical text to actual pixels, etc).

It makes reading a lot easier for me - and vastly decreases how tired I feel after a day of it.

hansword · 4 years ago
I had an old iPad (before retina) and used it for general tasks, sometimes. My newer hiDPI iPad has become my primary device for everything but actual work.

I would never have read a book on the old iPad, I read several in hiDPI. It really changes the way you read if the fonts are (perceptually) as crisp as print.

For a programmer, screen real estate (dependent on scaling). I look at 4k 100% scaling as having condensed two 1080p monitors without bezels.

Switching from 1900x1200 to a 4k monitor was night and day for me. So much less eye strain by the end of the day.

Better text rendering is the main advantage. This means that you can set text sizes smaller and have a lot more usable screen real estate.

It's a gpu power consumption/battery life issue. Putting a high res display in an Air clone ("ultrabook") means poor battery life unless you can also make a very efficient GPU (which so far only Apple has done).

The battery life on my 4k XPS13 is atrocious and it gets hot enough to burn my thighs.

Silica6149 · 4 years ago
Battery life vs display resolution is always a balancing act. Even macbooks don't have 4k displays for this reason. Makes me wonder why manufacturers opt to make so many 4k laptops compared to 2k ones.
ClumsyPilot · 4 years ago
everyone talking about HiDPI, but everyone seems to miss display brightness. Standard displays are 200 - 300 nits, woefully inadequate if you are going to use it on the balcony, terrace or even near a big window. Very limiting if you open a laptop and it's unreadable.

For the first time I splashed out on a premium 4K monitor 32", and at 600 nits you forget the word glare - there is no glare if the screen is brighter than the sun.

kitsunesoba · 4 years ago
Yes, this is crazy frustrating. The problem isn’t exclusive to boutique Linux laptops either, a lot of manufacturers use terribly dim panels that are barely usable in a well-daylight-lit room, and exacerbating it they’re glossy with extremely ineffective antiglare coating, which adds a thick layer of glare that the dim backlight doesn’t have a prayer of cutting through.

Even expensive laptops can have this problem… I briefly owned a $2k+ ASUS ROG G15 that had an otherwise nice screen (15.6” 2560x1440 144hz IPS satin finish), but had a 300 nit backlight which rendered all that moot except at night.

This is one of those things that Apple nails. The MacBooks I’ve used for work have all had displays bright enough to handle a bright room with ease with very little glare despite being glossy. My Thinkpad X1 Nano also has a matte 500 nit display that’s quite nice.

Intel does a fair bit of exclusivity deals to prevent vendors from making certain pairings. It also didn't help that amd mobile CPUs were budget options for a long time. Manufacturers haven't caught on to the demand yet really.
bedast · 4 years ago
It depends on what you're looking for. There's been a withdrawal on focusing on 4K displays in laptops. Most of them exist as a marketing point, but provide no ancillary benefits.

One thing you might notice is "low res" displays tend to support things like higher refresh rates, might have better color and HDR

I have an ROG Flow X13 2021 with the 1980x1200 display. This "low res" display supports higher refresh rates, variable refresh rate, has good color and HDR support, and works quite well for a 13" laptop.

virtualritz · 4 years ago
Nope. See e.g. my reply here elsewhere about the Xiaomi RedmiBook Pro. These are available since a while with ~240ppoi screens (3.2×2k). I.e.the 2021 model already had that resolution.

Also Huawei's MateBook laptop series has been offering AMD CPUs + HDPI screens since years, afaik.

Amazing laptop. I'm never going back to a small screen or a non 3:2 screen

Very hard to source though. Had to have it shipped specially from China

dark-star · 4 years ago
I wonder what's with all the "3:2 screen" aficionados recently.

Some years ago, a 3:4 screen was considered "bad" and "unusable" and 16:9 or 16:10 was what you needed to have. Now 16:9 is bad and 3:2 (pretty close to 4:3) is back in business?

Is this just about chasing the latest fad? I mean 16:9 or even 16:10 has so much horizontal space that it's perfect if you do software development for example. Why is it so common now to give that up for more vertical space?

lhl · 4 years ago
A few notes that may or may not matter to people:

* great res/aspect ratio, but claimed 300 nits, which is good enough for most indoor usage, but not in brighter environments) - that being said, Notebookcheck tested theirs at 350 nits

* RAM is soldered so you're locked into 16GB (M.2 wifi and 2280 SSD can be replaced)

* no USB-A ports

Overall though it's a pretty great laptop, can't wait to see how the Ryzen 6000 version performs (and if it had a 32GB version would be high on my personal shopping list).

I've seen Ryzen 5000 series laptops with premium displays. I wouldn't consider 4K to be the only metric for that, though. My current Ryzen 5900HS laptop (from 2021) gave me the option of a 1920x1200 display or 3840x2400 at a lower refresh rate. Both displays have good color support, HDR, etc, but I went for the 1920x1200 display model for the smoother experience.

When I came out of laser eye surgery, I ended up with exceptional vision. I'd have to pixel peep to see a difference between those 2 display options. I would have preferred something that met half way in the middle, but this DPI is fine for the display size. Outside of that, I get good color accuracy, good brightness with HDR, and the high refresh rate with adaptive sync makes for a very smooth experience.

Do we not consider features like that also premium?

rez9x · 4 years ago
My experience has been that Linux is bad at scaling HiDPI. Maybe KDE is better. In Linux-specific forums and chats, I've seen many people comment that they go out of their way to buy a 1080p display to avoid the scaling issues.
sudosysgen · 4 years ago
None, I have an AMD Ryzen laptop with a highres display (1440p), and there are with 4k displays. It's just that a loooooot of laptops you're seeing are going to be rebrands of these ones.
syockit · 4 years ago
I have a 4K display AMD Ryzen laptop (Asus ROG Flow X13 2021 edition), so yes it's actually possible. The Japanese fonts look really pretty when everything is scaled 200% (to be equivalent to 2K display). But I value real estate so I still have everything on 100%.

For some reason, the 2022 edition lineup no longer offers 4K display.

oblak · 4 years ago
I guess you weren't looking hard enough. I am writing this on a fairly light and slim machine, equipped with Ryzen 5800 and a 16:10 2560x1600 @ 120Hz display. I used to have a 14 inch model with an even higher resolution at same refresh rate. Both were ~1k euro, depending on exact configuration.
usrn · 4 years ago
If I were to buy a new laptop I'd probably avoid high DPI displays. I can display fonts small enough that I can't read them even though the screen can resolve them on the older 1080p screen my thinkpad has. All the high DPI means is extra trouble and I think they know this.

Nope. Even HP sells a 13 inch 2560x1600 Ryzen laptop for about $700. Asus goes even higher resolution on their 13 inch OLED at 2880x1800 but it costs more.

But I'm not sure there is a difference between 1920 and 2560 for most users at 13-14 inches.

High DPI on something like a phone screen makes sense since it is often used so close to the face - but are people really getting this close to their computer displays?

For a 1080p 14" screen, and a person with 20:20 vision, you would need to be closer than 50cm to the screen to be able to discern any visual differences. Hackernews has lots of people who like to claim they can tell the difference, but the science of visual acuity is against them and they never back up these claims with studies or experiments.

Given a blind A/B test at a normal desk viewing distance, I'm doubtful any of these people would be able to pick out the difference between 1080p and 4k on a screen so small.

seltzered_ · 4 years ago
High DPI displays have been available for a decade, since the 2012 retina macbook pro. "Science of visual acuity" aside, the difference is noticeable.

I use a tablet pc and find it bizarre some vendors sell the m with 1080p displays when it's meant to be used closer to the face at be times. 2-in-1 budget laptops also have the same issue when using 1080p panels

The Ryzen 7 5700U is Zen2 based: https://www.cpu-world.com/CPUs/Zen/AMD-Ryzen%207%20Mobile%20...

Not that great a deal when Zen3 based notebooks (5400/5600/5800U) have been out for over a year already.

It is baffling to me why AMD chose to have the odd-numbered 5000 series (5300/5500/5700) with Zen2, and the even-numbered 5000 with Zen3.

Oh no, it's actually even worse than that.

5300U/5500U/5700U are Zen 2 (Lucienne, Renoir Refresh).

5300G/5400U/5700G/5700H are Zen 3 (Cezanne).

I find it remarkable how AMD started a completely new, fairly sane naming scheme from scratch and screwed it completely up within two generations (Remember 3200G/3400G? Pepperidge Farm remembers).

webmobdev · 4 years ago
I remember reading somewhere that this kind of convulated naming convention is intentional (both by Intel and AMD). Consumers prefer to buy the latest and fastest CPU they can afford. Such convulated designations confuse the consumer on what is the latest, and ensure old / previous generation stocks can still be sold for a good price.

The number of spam connections emerging from China and Russia are huge. For small firms who might not have the expertise or the budget to host things on CloudFlare, wholesale blocking off IP addresses from the two countries results in almost 100% decrease in spam.

Is there any high-end Linux laptops with matte displays? Everything seems to be using glossy displays, which after being used to use a matte one, is simply impossible to use, especially when using the laptop outside or in a sunny room.
dmos62 · 4 years ago
You can apply a third-party non-reflective screen-protector.

My guess is that the main reason many devices have reflective stock screens is that a reflective screen has higher brightness, while a matte screen is dimmer. I think most will agree that matte is preferable in actual use, but when looking at basic screen benchmarks or when looking at a bunch of screens in a hardware store, buyers are attracted to bright screens.

Writing this from a X1 Gen9, I wouldn't call the following "very good". Not sure if it's already fixed in new firmware (and couldn't google the support forum right away), but I had to

* switch sleep mode to stop it from getting hot while asleep;

* disable touchpad in BIOS to stop it from spinning fans while awake — great for me because I don't like it anyway and vastly prefer the trackpoint, but people not used to this consistently go wtf while trying to show something on my laptop.

I may or may not be super knowledgeable on the subject have the KDE Slimbook team considered going full with ARM chips instead of the x86_64 processors?

I keep reading how ARM is more "efficient" and lower power consumption altogether. I also noticed that some Windows-laptop devices are shipping with ARM as well. (Windows on ARM not being new if you have been following Microsoft closely)

viraptor · 4 years ago
Arm is mostly more efficient, but the overall performance is not there apart from Apple silicon. You can get some laptops with qualcomm chips and they're weak - basically an underpowered netbook class. The competition is missing because of a deal between qualcomm and MS for Windows laptops (https://www.theverge.com/2021/11/23/22798231/microsoft-qualc...). So if you want to do something serious, there's very little choice.

Then there's the issue of running Linux on SoC where Qualcomm and others are not super keen on providing open support. M1 is going to get reverse engineered support for all the devices first because they offer hardware people actually want.

But on that note I feel like a budget laptop for the masses with ARM-chips would be quite the spot for many people include my father. he doesn't need any application just being able to use a browser. ( I guess, a more open, less shady Chromebook-like equivalent).

Well, I guess I just say this because my experience with the m1 chip has been way over the top to the point I haven't really noticed any slow down with docker/vscode/etc etc.
