slow quartz
For context: This is for a laptop GPU dongle, I will mainly use it for graphical editing and CAD (Affinity Photo & Designer, Davinci Resolve, Onshape, Unity editor) and also for AV1 video encoding.
I'm considering buying a GPU in the first place because I feel my laptop's 7840HS internal GPU is laggy for the above applications.
I occasionally play games but this is not a priority. I'm also not considering running AI inference since I have a dedicated server for that.

the intel arc gpus the letter is the code name for gen
and there going in alphabetical order
you can wait i gess
if was me i try looking for a nice used gpu

Or just an B580 if you dont have patience, 4GB diff
haughty sonnet
GB dont matter
What does then? Performance wiese an B580 should beat an A770 not?
tacit arrow
if it dose have 16GB it allso has a wider bus/more core

yes b580 beats a770
haughty sonnet
Then that it is

ig A770 is the "nice used gpu"... they're selling for really cheap now.
though tbf B580 isn't that much more expensive either...
idk, B580 and A770 seems very similar on paper:
I want to know if there are any benefits to having a B580 instead of A770 for being newer?
haughty sonnet
Slightly better drives perhaps

driver?
haughty sonnet
ah yes...
slow quartz
hmm right
tacit arrow
they use the same drivers
slow quartz
they use the same drivers
yea that's what I've thougut

The A series have fucking awful driver implementation. It’s Intels first outing. Do not buy an A GPU.
haughty sonnet
Got an B580 myself and am happy, so i can speak for that

Okay bad news for anyone reading this thread in the future:
Intel GPUs does not work with thunderbolt 4 GPU dongles at all, probably due to its higher bandwidth requirement...
So I decide to give up and swapped for a 2060 instead 😭

Can you not limit the bandwith?
slow quartz
Can you not limit the bandwith?
I haven't tried, how do I do that?
haughty sonnet
In a BIOS you could set ithe pcie slot from 5.0 to 4, 3 etc.
idk how it works with your setup tho

it seems like I can't set PCIe speed on the eGPU adapter... and it's limited by Thunderbolt 4 speed anyways
this is my setup btw
haughty sonnet
oh my, such fancy
slow quartz
oh my, such fancy
now it's way less fancy with a 2060 lmao
slow quartz
never saw pcie cables with such thingies to them
oh yea I made the PSU cable myself, but the eGPU adapter was bought from taobao
I just had a 750W server CSPS PSU sitting around so just used that
downside it's loud AF under heavy load... I need to replace its fans some day
how loud it is
haughty sonnet
I would worry more about the lifespan of that PSU
From my experience most server PSUs are somehow trash, while most user grade ones can last a decade no problem

From my experience most server PSUs are somehow trash, while most user grade one...
yea that's expected, most servers have dual PSU slots with one for backup
but tbf it's cheap anyways, so I don't mind replacing it if it fails
a Huawei 750W CSPS PSU sells for CN￥45 on taobao, that's US$6.3
haughty sonnet
Thats nothing
slow quartz
yea right?
