Hey guys long story short I need a PC than can handle building VR sims using blueprint for my post doc (neuro).
I’ve already ordered parts for a lab PC, but the way this project is going I’ll need to be able to work on it at home as well, so now I need a rig for home.
A friend of mine is giving me his old 1950x & I’ll splurge on a EVGA 2080 Super (which model idk).
Besides that I have no idea what to do with, I’m working 12 hr days and my brain is fried by the time I get home I can’t process the more technical stuff. I only just realized that for my office PC (1920x sitting in a ASRock x399m) spending the extra money to get 64gb DDR4 3600 wasn’t great because it’ll never hit those speeds (right?).
Any suggestions would be great, I’m trying to keep this build (CPU & GPU excluded) under $1K. Thanks!
The bigger shame is they have no low cost 12-16 core option for future Threadripper for people that just want a cheap CPU with tons of I/O for Machine Learning. Threadripper PRO won’t work on Threadripper TRX40, so you were screwed out of those cheaper processors if you wanted 64 lanes.
Do you mind explaining what a single core IPC is, why unreal needs it, and what the 1950x has in relation?
The PC ordered for the lab is a 1920x, x399 taichi (maybe the x399m), 64 gb Ripjaws V, a 2080 Super (XC Ultra Gaming or Black Gaming). I gave my lab manager a list of parts and it’s unclear what they ordered for some parts like the mobo as it hasn’t come in yet. I had less than a week to put a parts list together and tried to crowdsource as much info as I could from my friends who VR. Unfortunately the lab machine will be off network because I work in a hospital and being on network means HIPAA. So the idea was to put together something self contained that could build and run simple VR sims.
As far as ML, I don’t do it often - and when I do I’m just optimizing parameters on my pc and then shipping it off to a server because Matlab is powerful but slow. If my post doc gets extended it’s because I’ve picked up a grant, I’ll budget a few grand for a blazing neural network pc when (hopefully) that time comes.
ipc–> Instructions per clock. I’m simplifying this a fair bit, but it’s basically how much work can be done every clock cycle.
Games (and by extension game dev) need high IPC cores but not many cores. (6 or 8 cores with hyperthreading are enough)
The deal with the 1950X is that it had many cores for its time, but they were relatively slow cores. In high threaded workloads, it will shine, but for game dev it’s not very quick, even compared to low core Intel equivalents from 2017/2018.
There are also other factors like the memory access latency of the older Threadrippers that seriously disadvantage them in tasks like gaming etc.
The 1st and 2nd gen of threadrippers are not good for gaming (and game dev probably) because they were designed with other goals in mind (high performance compute).
On the other hand, 3rd gen threadrippers (which are on another socket) fixed the previous gen shortcomings and can game very well, thanks to the high ipc of zen 2 cores and memory access latency improvements.
Ahhhh OK that makes sense! I was under the assumption threadrippers were good for gaming! Well darn.
The work PC is half here, waiting on a few more parts. Our starting place was a $2k Gaming build outlined on Tomshardware and I had to start subbing out different components due to parts not being available.
Ok thanks! Looks like I’ll be able to use 3 of the old cables they have the same plug in pattern both are Yestone P01001 4 but the part that plugs into the PSU (LB57) looks different. I’m just trying to figure out how to wire up my case fans properly. I’m debating adding a few 60mm fans because it looks like their might be room for it.
Sort of, we have similar interests in restoring vision. He does glaucoma, we focus on patients with massive stroke-induced vision loss.
Here’s a cheesy example of what it’s like:
I didn’t listen to the whole podcast but that was one of the few times I could listen to someone discussing neuro stuff without shouting “THAT’S NOT HOW THAT WORKS” at least once.
Edit - So for the PC I’m building for home, I really like the Thermaltake X9 cases in white, but I can’t find any online. Do y’all have any recommendations for similar cases? I also like this one but I can’t find out what brand or model it is.
