Laptops vs desktops for 3d

[ragnar28]

Hi guys i realise this is probably going to be one stupid question given what ive read sofar on the forum regarding hardware. So here goes ... Im a web dev and recently ive started going into motion graphics. I find even some of the best laptops struggle with things like adobe premiere and davince with regards t redering and i went and looked it up and basically was told this studd isnt meant for laptop... Now i find that hard to believe but since i have a huge gap in knowledge for a web dev on hardware what are the main components related to " better 3d rendering " A graphics cards , Ram , Processor speed?

Im looking to upgrade and i just saw my friend make a massive purchase mistake on a laptop which we all though was pretty good ofcourse even the salesman talked him up about how this asus 3.1ghz i7 16gb ram ssd with nvidia graphics card ....was going to run everything and now he is back on a pavilion g7 because even that is faster. I dont want to end up like that.

Any advice would be appreciated

What hardware is good for rendering depends on the software and what you're doing with it. Adobe Premiere Pro can benefit a lot from CPUs with higher multithreaded performance (more cores), from 32gb RAM, and from a powerful GPU for example. Blender rendering can be mostly about the CPU, Octane can be mostly the GPU, as far as I know.

Intel are, I believe, releasing new or refreshed CPUs for laptops with more cores. They may be useful for what you want.

oh yeah i remember scratching around on day and saw a option to disable multi threading as somebody told me in some older programs it can cause crashing... i assume that has to do with the cores as you call them.

So i also heard that sometimes adding ram depending on "slots" they said can actually cause a degrade in performance i assume if done wrong maybe this is what happened to the asus. Maybe i can gather the specs for you and if you have time identify a weak link .... because your post suggest it can be multiple things.

As was noted in your first topic https://www.pcspecialist.co.uk/foru...Ragnar-Is-here&p=400450&viewfull=1#post400450, the forums are mostly for PC Specialist computers so a full troubleshooting of your friend's Asus might not really be practicable

In general terms there are quite a lot of things to consider. Like whether the hardware in the newer laptop was really that much better than what he had before anyway. i7 is quite broad. Some dedicated graphics cards aren't much better than integrated graphics. Some SSDs are pretty slow. Then there are hardware faults to consider, including thermal issues. Software issues like bad drivers, or settings in the software.

It will depend on the software, but in most software I've seen discussed on the forums, disabling multithreading isn't something that needs to be done very often. Not all software that supports multithreading (or claims to) benefits as much from a CPU with lots of cores as it might do from a CPU with fewer, faster cores. But that doesn't mean that leaving multithreading on actually hinders performance.

But this is all very vague and general.
