Cpu for unreal engine 4 dev. i5-7600K or i7-3820?

[Edgar R. Zakarian]

Hi, 
The choice is between these two available systems to avoid a whole platform update.

I7 3820  - 16gb DDR3 + 3070ti
i5 7600k - 16gb DDR4 + 3070ti

 

Which do you think is best for unreal engine 4 game dev?

No don't suggest platform upgrades...

[Levent]

LGA2011 parts are still expensive and I honestly wouldnt consider switching to when I would be using 3820. Considering you already have 7600K and the RAM, just get a graphics card.

So for unreal engine 4 development you would suggest the 7600k over the 3820? paired with the 3070ti?

I would not suggest either of them. This was due to this specific line in your post.

One is an 10 year old HEDT platform using the cheapest CPU that was available on that socket. Other is a 5 year old quad-core cpu with no SMT and doenst have a great upgrade path. I would recommend getting an AM4 platform or LGA1200.

 

One is a total waste of money, other is less waste of money.

Let me rephrase my question.
So if you had a gun to your head, Which of the two platforms would you pick to develop Unreal Engine 4 games?

I would take the bullet. Second choice would be LGA2011 but I would most definitely NOT stick with 3820.

Thanks man! that made me laugh hah!! I guess rough working days on an aging platform huh

[Edgar R. Zakarian]

Is there a cpu upgrade on that old motherboard/platform that's good to upgrade to? I saw old CPU's are cheap, because they rarely have functional motherboard, so a lot of cpu excess on the market?

So this is just a random Layman's opinion, but looking at your flair, it says you're using a 2400G in a living room pc. Honestly, that right there even being a Zen 1 part would probably outperform both the 3820 and 7600K for multithreaded UE4 development. Sandy Bridge E whilst good at the time, is starting to age out a bit, and the 7600K is just kind of anemic for anything remotely multithreaded. If it were me, I'd repurpose that 2400G into my main pc, and stick the 7600K in the living room pc, as I think the additional threads of the 2400G even whilst using a slower architecture, would probably come out on top for that kind of work most of the time. 

 

That being said I know next to nothing about the specific task at hand, and this mostly an "educated" guess just based on what I know of the performance levels of the cpus mentioned, so of course you'll have to verify with testing and what not. The 7600K will probably have faster single threaded performance than the 2400G, but not by a whole lot at stock. If you were to overclock it, it would probably end up being around ~15% faster per core than the 2400G, but still wouldn't close the gap in multithreaded performance because of the lack of hyperthreading. I really don't know which would ultimately end up being faster in this scenario for UE4 specifically, but I would imagine they would both probably be faster than the 3820. Again, testing is necessary here.

Very much so this. The 2400g is by far the best option here. Yes single core wise the 7600k is about 15-20% faster but the extra threads on the 2400g MORE than make up for that.

 

This would have also been why I'd suggested the 3820. Sure it's old but at least it's got the threads you need. However since that 2400g can also be an option that system is by far the best choice here. That and you can easily cheaply upgrade it to be a very good system whilst on the others that is simply not possible.

Yeah so the situation is that my sister is working on Unreal engine 4 game/art development. 

My current desktop is the one with 7600k & Full ATX motherboard. (750W PSU 80+Gold Corsair)
My living room pc 2400g (Mini itx) tiny HTPC. (450W Integra PSU)

Her current pc: i7-3820 with GTX 1060 (650W 80+ Gold PSU Corsair) and she's experiencing major lag issues.

When we checked usage, we saw that the GTX 1060 was a major bottleneck. 

 

So GPU upgrade is necessary. However I was wondering, if she was to buy a 3070 or 3070ti or similar, if it would be worthwhile if she got my setup (7600k) for her 3070/ti and I got her old setup. I can manage with her setup I think, I don't play very CPU intensive games other than CSGO & Rimworld (Heavily modded).
For anything above 3070/ti it seems she would need a higher wattage CPU than her 650 anyway. That's why I thought just swapping PC's. 

Also she uses a raid card to run like 4-6 harddrives in her PC, so Mini ITX isn't an option. (Some of her old SATA ports on the old mobo aren't working xD)

let her keep using the 3820 system it will do better than the 7600k for game dev by far due to the extra threads.

 

650w is already not enough for a 3070ti and the minimum for a 3070. What 650w psu is it?

It's Corsair TX650M
Alright thanks for the input. I guess she's better off with it so far then. Maybe we can just stick to upgrading the gpu only then.

For now sure if you get a 3070. A tx650m from that far back in the day is already not recommended for a 3070 but you can try and see if it works. If the psu shuts off you know what the issue is. A 3070ti is well beyond it's capabilities.
