Desktop versus laptop

And since it's an HX (unlocked) CPU in this laptop it's not a low power machine.
Which perversely makes it worse. The crappy laptop I bought early this year is fine for surfing the web. It'll likely be fine forever to surf the web.

Most people who buy a powerful laptop are buying it to do power intensive stuff. The stuff that tends to get harder or more specialized over time.
Yes, I imagine that in a few years what seems to be intensive today (Deep Prime exports) will seem like simple edits compared to whatever comes next. But, knowing myself I am looking at maybe a 3-year time horizon for this machine.

There are some downsides to using a laptop (see below), but nowadays laptops are quite powerful and many are desktop replacement while being very portable.

Laptop GPU power depends a lot on the TDP. For example 90w 3080 will be slower than 145w 3070Ti.

There are some major downsides to owning a laptop however, but they apply to specific people, like myself:

- Fan noise. My desktop even though it's built with 12 fans is a lot quieter than my laptop with 2 fans. Thermals are much lower therefore less spin is needed. Laptops can get way too loud for me and I usually run them at silent mode which limits their performance. But I'd rather have a quiet laptop.
My current desktop gets quite loud (it's a small form factor with probably poor ventilation as a result). I think I will have to accept some noise either way (it is easier to wear slippers than to carpet the entire world!).

- USB slot amount and power requirements. I have a total of 50TB connected to my desktop with Plex server as well as backups and a simple laptop is unable to provide that much power as well as connection. Granted I can get a dockning station, but most don't have all the connectors I need and those that do cost over €300-€400.
This one is pretty port friendly for sure, and I also like the fact that the ethernet, power, and USB-C (display port) all run out the back so it should look clean on my desk.

- New laptops are never as fast as desktop and the power shift between CPU and GPU can limit you in many cases. For example it can favor the CPU in CPU heavy tasks and give more power to it while taking away from the GPU.
Interesting. Again with the throttling. hmmm.

I'm a nerd however and use my PC from media consumption and as a server and work/study to gaming to video/photo editing so I like to build my own computers. But if I only wanted a PC for productivity and editing I'd get a laptop and a high quality external screen and call it a day.
As may I!
 
For me, in order:

1. Screen size and positioning (but can buy an external screen for laptop)

2. Heat dissipation and fan noise

3. Upgradability

4. Keyboard

5. Cost for similar performance level

All of these favor desktops, so their value should be balanced against the value of mobility. Different mix for different people. With various data networking options available today, it's easy to have both and work back and forth with both on a common data set.

In that case, you may have an easier time adapting to a high-end laptop than I would; quiet operation is high on my priority list for both desktops and laptops, with the exception of gaming where I use earphones.
 
I used a laptop for a year or two , even had a Wacom in the bag, and used to edit clients work on site for urgent publishing stuff. I hated the variation in screen brightness as you moved the angle of the screen , made judging a pain and all work was gauged by the info numbers.

I found them a pain and finally rested on a good desktop and a tablet. I can control the cameras from the tablet and use it with a tablet holder on an arm next to the camera.

PC's are so easily adapted to task and adapted to change, or upgraded. Even changing the motherboard and chip means you can retain the case, drives, graphics card power supply etc provided you over specified at purchase.

When was the last time you opened it up, blew the dust out in general and off the inside of the fans, and then vacuumed them out from the outside?

Also, if you are not using an internal HDD, you may have an unused HDD bracket that can be easily removed, opening things up which helps airflow.

Finally, small-form-factor cases are easy to slip into tight spaces, which can obstruct airflow in and out.
 
Yes. I don't know why people don't immediately think of the big difference between big screen / little screen.

Whenever I go from desktop to laptop the first sensation is one of cramped confinement.
To me any of the computers will do the job , it is all about the screen !
Yes, that's true, but for me the plan always was/is to connect the computer (either this or a desktop) to a nice, large, 4k monitor.
 
There is an entire science exploring acoustics, and air movement can create all sort of waves, not to mention poor fans . Luckily YouTube is full of case reviews and the good ones look at efficiency of air flow , acoustics and cooling.

I tried A Phanteks case this time and used good fans as they suggest , with the Corsair 850 w PSU running silent, the BeQuiet CPU fan doing what it says, and the Phanteks fans , the audible noise of the key board is my only sound created !

Keeping it clean is a big help too , but the Phanteks case has removable filters to catch the crud.

My dander exuding dog, who sleeps with her head on my computer which is stuffed under my desk, says "how dare you!!"

Seriously though, I'm sure you're right, I'll take a look.
 
I'm shopping for a new computer for photo editing (Deep Prime, focus stacking, panoramas, layers in Photoshop, etc.). I have mostly been looking at desktops and the ones I want are coming in around $2200 (something like i7-12700, 32GB ram, 3060 gpu, 2TB ssd).

Then just for fun I started looking at some laptops and was surprised at the low prices. I'd be looking at, for example, an OMEN with:

i7-12800HX

3070 Ti (laptop)

32 GB ram

2 TB ssd

is the same price: $2200.

It seems like the 12800HX might be quite close to the i7-12700; the 3070 Ti (laptop) looks better than the 3060 (desktop), etc.

Other things being equal, I would prefer a laptop (for the rare occasions I might want to move it, convenience, etc.).

Am I missing something? It seems odd that a tiny little gpu that can fit in a laptop (and be cooled there) could be better than the massive double fan 3060, etc. Would this laptop setup really get me Deep Prime exports as quickly as the desktop?

Why would I regret getting the laptop instead? Ports? OK, but I'm not port starved.

I feel like I must be failing to consider something else.

Thanks!
I bought a six-core Laptop two years after getting my four-CORE Desktop. The CPUMark measurements were great, the Laptop was 50% above the Desktop.

However when I did my own comparison with a quite routine job - converting 200 RAW files to JPG in DXO - the Desktop was significantly quicker. After just a minute or so the Laptop was throttling back the CPU speed by 50%. while the Desktop was just churning away with the blower making an enormous noise and the CPU heating up to 80°C.

The Laptop has a nice screen and sometimes I take it to process images on long trips but basically I do all of my serious postproduction on the Desktop when I get back.
 
Laptops. All Day.

Good choice.

I opted to do a similar Dell laptop plus a docking station for a couple of monitors and a HD. It was cheaper than upgrading my desktop.

I don't process a huge volume of raws at any one time, so I am not worried about the overheating.

Maybe in another year or two I will be back to a desk top.
 
Wow. I'm impressed.

I wonder whether its IPS display is 8 or 10 bit? I'd expect the latter. (8+2 FRC at the least.)

If I had to guess, its main drawback may be battery life. That could be the inescapable price of having a really powerful CPU and GPU, even with optimizations for when the laptop isn't doing serious processing (or 3D gaming). I presume that it does Optimus graphics, for power saving. (The I7-12700H includes a good iGPU.)
 
Do you want portability or power house?

Desktop parts are always more powerful than laptop parts. More power draw and better thermal dissipation are the big advantages for desktop computers.

Quick summary CPU and GPU performance:

Same scenario if comparing with i9 mobile vs i9 desktop. Desktop wins in performance.
Same scenario if comparing with i9 mobile vs i9 desktop. Desktop wins in performance.

Same scenario if comparing with 3070/3080 mobile vs 3070/3080 desktop. Desktop wins in performance.
Same scenario if comparing with 3070/3080 mobile vs 3070/3080 desktop. Desktop wins in performance.



Like others have pointed out, desktop can sustain high stress load without throttling or min throttling, whereas laptops throttle quickly to control heat.



It pretty much comes down to what you want in a computer. And Windows laptops need to be plugged in for that performance, on battery, they usually go into battery saving mode with low performance.

Lenovo's site claims 100% coverage of sRGB – but I don't see any claims about Adobe RGB coverage, DCI-P3 coverage, or bit depth.

Note that 8-bit laptop displays are sometimes 6-bit with 2-bit FRC.

https://www.lenovo.com/us/en/p/lapt...gion-5i-pro-gen-7-(16-inch-intel)/len101g0015
A review, that includes some color space testing: notebookcheck The claims are 97.6% sRGB, 70.9% Adobe RGB, and 68.7% Display P3. (Is that he same as DCI-P3?) There is no mention of the bit depth of the display, at least that I spotted.

It's a bit more complicated right now. Say you're buying a Dell then you're desktop CPU even if it doesn't "throttle" due to heat will drop down to PL1 after a short burst and get lower clock rates. But if you get one from a system integrator or build it yourself most of those motherboards are set to stay at the higher PL2 forever.

Also that difference is surprisingly small, they've made a lot of gains in efficiency.
