Hello everyone
I’m about to get a new PC to begin serious business in Unreal Engine for game development and I’m considering a build with:
CPU i7 12700 KF
Asus 4070
32gb of DDR4 RAM
2 To SSD
The person I asked to make the build told me that the i7 12700 KF is a specific type of CPU that doesn’t have an integrated GPU but is able to overclock. I considered it to be pretty good for the usage I intend to have in Unreal Engine but can you tell me if the absence of integrated GPU with the CPU could be an issue for UE5? I know that if the GPU goes down, the PC won’t be able to be used btw.
Also, I prefered DDR4 RAM over DDR5 because of the price and from what I understood, it’s making a huge difference in performances. Is that true ?
Also, if you see anything wrong with that PC buid, feel free to tell me but I think that it meets the current minimal standards to work properly in Unreal Engine from what I read.
Integrated graphics is a feature designed for computers that don’t have sole dedication to graphical tasks. Any PC intended for applications that need heavy duty graphics support will have some type of dedicated system. You PC should default to using the GPU for high-demand applications, assuming you connect your monitor to it via HDMI/DP (DO NOT PLUG IT INTO YOUR MOTHERBOARD HDMI, YOU WILL HAVE MASSIVE PERFOMANCE DROPS/BLACK SCREENS). If for whatever reason the GPU failed and your PC reverted to a hypothetical integrated graphics system, UE5 would probably be unusable anyway.
I’m running UEFN, not UE5, on a 9th gen I5, 3060ti, 32 gbs DDR4 with 3.5 tb’s of storage. I have no issues other than lag if i’m dragging 1000+ duplicated objects. Sometimes I am running chrome, brave, photoshop, blender, Fortnite, and UEFN all at the same time. Only then it may get a bit laggy but its usually if i’m baking something in blender at the time.
It may be worth going a generation up to the 13000 series CPU’s if you can afford it. Make sure the GPU has at least 8gbs of VRAM. Also, overclocking today isn’t what it used to be compared to 10 years ago since most CPU’s run close to their max clock speed. It’s not something you need to worry about, but if you want to get into that community make sure you have a good quality PSU and a motherboard designed for overclocking.
As in the GPU “going down”, meaning total failure, that is such a rare scenario. They will last the lifetime of the PC. If you’re worried about that get a warranty for the GPU.
