Hardware / Re: New Build options - mobility vs. utility
« on: 2024-02-11, 19:43:00 »
Hey there, many times I had similar dilemma :- ) The best answer really changes through years.`

(I try to be impartial in my answer below, but I want to note that I receive few free laptops from Intel here and there. But I built plenty of other computers myself, from SFFPCs to big server-builds, so I can compare stuff from experience.)

5 years ago I think, laptops were really weak (although there were few desktop Ryzen in ECO mode (65W) put into few Clevo chassis), so I built portable SFFPC with Cerberus-X and put 18-core i9 into it, was still bit weaker than my 32-core Threadripper at that time, but so much more powerful than any laptop on market. This was quite heavy SFFPC and it wasn't easy to lug around. The really small SFFPC were impractical in shape and only supported ITX boards, which mean 2x32GB ram limit, too little. Nowadays, 2x48GB ram is plenty for ITX boards and mainstream laptops since 96 is quite bit closer to 128 than 64GB was.

2 years ago, Intel came with HX chips, effectively desktop CPUs in laptop. Shortly after, AMD came with their own HX, which is lot more energy efficient :- ). But there are few laptops with it only, mainly Lenovo Legion series. I have 12950HX Dell Precision 16, 13950HX MSI Titan GT77, and will probably get Razer Blade 18 14950HX at some point.

My observations:
- These laptops are really powerful, the CPU chips themselves are absolutely identical to desktops. But that depends on chassis and how much they can supply power and cooling. For example, the Dell Precision is rather thick and heavy workstation (not the XPS-body style, the big-body version), but has rather weak cooling, so it's like 40perc. weaker than my MSI Titan.
- They are very loud if you set them to desktop performance. As in, people will be angry at you in office :- ). You can put on noise-cancelling headphones on. But you can just keep swapping between performance profiles and keep the laptop reasonably silent for most work, and set it on maximum only when you need it.

My MSI Titan, is big, ugly, plastic and loud. But it's otherwise absolutely identical in performance to 13900K, or 7950X, etc.. Engineering marvel. So the only time it would make sense for me to build SFFPC, is to build mini-Threadripper. Because mainstream CPUs don't outperform HX-series in big-body laptops like the Titan.
Medium-body laptops like Razer Blade are slighly more compromise, but they are more portable and easier on eyes (nice metal chassis, clean design, better display calibration from factory,..).

Unfortunately, all laptops of this sort are now like 4000-5000 Euro if you also want high-vram GPU before you even upgrade ram to 2x48GB.

Asus Strix and Lenovo Legion are most reasonably priced and have best performance/price value. Lenovo has better quality control. MSI and Razer are really expensive, with MSI Titan-series you get desktop performance (it's like the only laptop with 350W power delivery, insane thing), with Razer you get the only Macbook style body.

Laptops are imho much better than SFFPCs since you also get a display with them, so the moment you plug into external 27" monitor in office or elsewhere, you get free side monitor on the laptop itself.
SFFPC really only make sense if you want to maximize GPU performance, so they're really more like niche gaming builds. If you follow the Reddit/r/sffpc, then you know the audience :- ). 90perc. of them are super impractical and barely cost effective against laptop and unless they have 280mm AIO on CPU, the CPU performance is often just as laptop, so it's just the GPU working as intended.

I remember trying to trick this (in Max though) by using ShadowCatcher>RaySwitch>TonemapControl in DirectlyVisible Slot. But I don't remember how well it worked (or didn't work).

Killer carpet :- )

That would be behind the artificial cap of 4 RDIMM slots :- ) ?

Peak market segmentation, though it's logical and more like thrown bone to the HEDT crowd. Can't complain, they could have just skipped the non-pro stuff totally and everyone would be worse off.
I am bit sad the workstation market is back in the 10 000 Euro build segment like 7-8 years ago, but this come and goes in circles. Everything is expensive now, not much can be done.

1950X/2990WX were peak affordability. 3xxx were peak solid value/performance. 5xxx is not worth mentioning in any way. 7xxx is excellent performer, but back to high prices mostly due to whole package (motherboard + memory).

With everyone on GPUs though nowadays, not much excitement on internet for these chips anymore.

Not many kickass builds in this thread anymore either. Even I am not very excited about cpus, but that is because they've long surpassed my work capability and I am only limited by shitty single-threaded softwares like Max and my own inefficiency.

35
Is it because the TRX50 is now derived from WRX90 directly, just stripped of channels and lanes?

That will probably go for the physical boards themselves, paying same price and one gives you overclocking and other gives you the bigger physical layout for more dimms and pci cards.
In the end, you're just saying bit of money with non-WX chips.


36
Damn, I need to update my RDIMM knowledge before I confuse people :- ) Super sorry about this.
Anyway, looks like Threadrippers 7xxx even non-pro require RDIMM memory, so for G.Skill, that would be their Zeta R-series, not the Z5 series.

And yup, that's the https://www.newegg.com/g-skill-192gb/p/N82E16820374533?item=N82E16820374533&source=region

1600 USD you quoted above, uff.

You can always go for generic stuff like https://www.newegg.com/nemix-ram-256gb/p/1X5-003Z-01FM5 (1000 USD for 256GB DDR5 RDIMM 5600)
But I would probably buy the G.Skill for those Samsung ICs if I was building state-of-art workstation.

37
Wrong advice from me ;- ) Ignore.

G.Skill Trident Z5 series uses Samsung chips, and is among probably the most high-end kits on market right now. I can't imagine it not working :- ) If these wouldn't, none would.

That doesn't mean it will run at their XMPP/DOCP settings, and G.Skill validated those numbers for Intel Alder-Lake desktops. So you will be on your own to figure out the best stable configuration.

38
Is the dual Xeon 8480 ES, QS or Retail stepping? My older dual 8280s are extremely consistent in performance with my 3990X Threadripper for example.

It's been long time since I've used ES/QS builds, but a lot of shenanigans can happen between Windows Scheduler, Board microcode, Chipset drivers that non-retail steppings can be very sensitive to (unless manufacturers are using some more precautions, but the fault can be with motherboards as well).

What can be done to bypass these limitations is the old trick Vlado from Vray suggested almost 10 years ago, is to run multiple rendering sessions at same time. I've never personally done it, so not sure what is the best way today, I personally would try ProcessLasso, but experimentation is needed.

Of course, highly sub-optimal for single-renders, but doable solution for animations. And of course super-bad solution for workstation, but then dual-builds, even retail are generally poor workstations today.

Should we start ES/QS build thread btw :- ) ? Looks like golden age for this is upon us again lol! Lot more complicated situation with motherboards, but so many Epycs and Xeons and memory is very reasonable priced. Sadly I no longer need render-farm for my studio needs but I always loved building them.

Very nice, the colours and mood.

The design can be even more minimal without compromising practicality if you skip the board behind the kitchen top/stove. You really don't need it.
 
The brickwork is done very well but I find it nearly impossible with Corona to render rough or course brick (see attachement). I haven't managed yet to capture the fine but sharp "bump" real bricks have. A displacement would not work for these fine textural bumps and holes. It's almost like sandpaper also for the reflections. Bumps in Corona always seem to be a bit rounded of in detail.

I had to unsubscribe from FriendlyShade because I just didn't need any stuff he kept scanning, but he does this actually :- ) like.. 64 000 px big textures. Then you use like 0.5px Texture Displacement in Corona (and prepare all 128GB to be spent on one wall), but... you'll get that result :- ).

Fastest way is importing FBX files from Rhino3D :- )

Self-bumping up :- ) ? Heh it was so common back in day when most images were posted in Facebook Groups. Man I hated those groups.. such a rat race.

That's why I like Behance, you just post the work and let it live. Unfortunately, looks like buying likes&comments came to it as well, often very obvious for some countries (the same one who buy those fake likes on Instagram and else).

Anyway, someone selling LinkedIn likes ;- )?

42
thanks Aram, good to hear!

Now that almost 80perc. of my materials feature Randomizer and Triplanar, often both in row, that is not nice news. I did want better representation in viewport (just by taking any bitmap in chain), but if it's causing  performance issues now : /

Very smooth and clean! It's simple scene, but has no weak points so it works super well. Pleasure to look at.

But this is not bug-reporting thread :- ). My Max/Corona is super-sluggish and I am still on Corona10.

This thread gave me more ideas to test certain scenarios I didn't pay attention to before, mainly:

1) Show all viewports performance
2) Alt-tab in & out

That's on top of few I listed myself on first page.

I mean working in Max has been pain for past few years, I need to figure out what everything causes downgrade. Lot of it is Corona related on Materials in Viewport.

(To be truly off-topic, I would start how damn slow latest Photoshop is! What's up with that).
