hi,all.
My old computer is broken lately.
and I plan to assemble a new one.
I’m kinda entangled between intel 12400f AMD r7 5700x.
Their prices are similar but one is 6 cores and another is 8 cores.
which one is better for unreal engine,especially for compiling material and work with Niagara.
If one is better then another.will the advantage be obvious?
also I heard that 13th gen intel’s small cores are not compatible very well with unreal engine.is that true?
thank you very much.
5700x3d/5800x3d would be great, yes 8 cores better for your usecase than 6
Don’t know about small cores compatibility but you don’t need them unless you are building a laptop)
What does this even mean?
The E-Cores work fine, they’re efficient in certain tasks and idle in others - where single core peak matters the most, for example. You will see similarly priced AMD / Intel chips trade blows depending on whether you’re compiling shaders, building lighting, playing a specific game. It’s somewhat irrelevant as we’re talking about a few percentage points one way or the other.
I would avoid Intel 13th and 14th gen specifically for very different reasons, though:
You will see similarly priced AMD / Intel chips trade blows depending on whether you’re compiling shaders, building lighting, playing a specific game.
This is no longer true since the advent of the new Ryzen lineup which blows everything out of the water… 
However the 12th gen and equivalent Ryzen chips went head-to-head indeed. AMD had a slight bias towards gaming with the 5800X3d chip, ofc.
What is the CPU budget? Because these two vary in price significantly, meaning you could get 12400f and have £50 for another 32GB RAM kit… which is NOT insignificant all of a sudden. Or a better GPU?
This mean that you need this extra efficiency only on devices with batteries, on PC I saw people disabling those small cores due to performance issues.
Don’t need to look for a CPU with them on PC and especially workstation
This makes no sense whatsoever. First hand experience. Especially in UE. They load to 100% and make cycles go brrrrr. AND make the rest of the system responsive under full load. Pudget has a bunch of tests across all ranges and many scenarios, take a deeper dive to find out for yourself.
I wonder if you are referring to the early version of Baldur’s Gate 3 - that was one scenario (that I remember) where E-Cores created stutter, it was patched a week later or so. Admittedly, the E-cores only matter in games that can utilise / need the extra cores. Not many titles; those cores shine in production. And that’s what matters here.
Just a couple of days ago I saw game tests running on E-Cores exclusively with P-Cores disabled, for fun. It’s stupid but works surprisingly well!
Hi,
I don’t know how much they sell in Europe.in where I live they are almost the same price when adding the motherboard together.
It’s about 220 $ I guess (I converted my currency to USD with a online tool I found)
12400+a low-level B660m with 2 ram sockets.
5700x+a high-level B550m with 4 ram sockets(ASUS B550m TUF Plus gaming).
maybe the 12400 suit is 200~210 USD.but if I choose the same level motherboard as AMD’s. the price of 12400 suit will become more expensive then 5700x suit.
AMD’s motherboard is much cheaper then Intel’s for some reasons in my area…so I can only choose between them.
That makes a lot of sense. When it comes to RAM, it’s generally better these days to run with 2 large stick than 4 sticks due to XMP / Expo compatibility - especially for DDR5. One thing worth noting here is that AMD is DDR4 only, while Intel supports DDR5 as well - be mindful of that when choosing an intel mobo - they come in 2 flavours. Perhaps you already have compatible DDR4 RAM you can use?
12400 vs 5700x
Were I to choose between the 2 today, I’d opt for the 5700x - because I’m upset with Intel and it makes more sense overall.
I’d ask grandma for an early xmas allowance and splurge on 5800x non-3d and never look back.
I don’t know this …I was plan to get 16gb x 2 sticks and add more sticks later ,sounds like I need to get 32gb x 1 version.
DDR5 platform expands the budget too much…
no,this is a trap.there’s always better one and better one.i must suppress the Dopamine releasing.haha.
and…I’m an adult…
Haha anyway thank you.
Overrated, pfff.
get 16gb x 2 sticks and add more sticks later ,sounds like I need to get 32gb x 1 version.
I would not - a single stick robs you of dual channel mobo support. Get 2x16GB. Expo / XMP issues are mostly there for DDR5 which you’re not getting and get annoying when you try something above DDR5 6000+.
Get 2x16GB. Add identical set at a later date, if at all needed.
Very informative, because my knowledge of the hardware is a few years out of date.
