Question i5 12400 or i7 12700f with rtx 4070?

[Kellerman88]

Hi.

Pc noob with some upgrade question.
Spec today:

i5 12400 12th generation
16gb ram
Rtx 3060ti.
Powersupply 500w FSP FSP500-10AGA

Is it possible to get 32gb ram and rtx 4070 grapic card for this pc? Using it for 4K gaming in most cases.

If it fit i also wonder if the i5 12400 would be a bottleneck for the 4070 gpu?

Also could go with a i7 12700F instead, would this cpu fit the cards better? Checked the two cpu on benchmark and it only seems like the i7 12700f is 10% faster then the i5 12400?
For me i7 sounds much stronger with 12 cores so maby my research is wrong about this two cpu?

Appreciate some advice about this, if the 2 cpu i mention is almost just as fast, and how it would be upgraded.

Looked for the manual but i cant find anything about what motherboard it have.

First of all, you need to upgrade your PSU. 500watts is barely enough for a 3060ti, and is definetly not enough for 4070.

As for 32GB of ram, unless you actually need them, it's probably not necessary and won't perform better.

Now for the CPU question, the i7 is obviously faster than the i5, but for gaming, especially at 4K, this won't matter.
The i7 is 10-20% faster in productivity (Video editing, 3D rendering stuff like that) especially since it has more cores.
But for gaming, since you only need a few cores, it is probably only 5-10% faster, and in 4K even less.

Higher resolution gaming (1440p or 4K) is more GPU bottlenecked than 1080p which is likely to be CPU bottlenecked.


TL;DR get a new PSU, and get a 4070 if you want. Leave the CPU and check if you actually need 32GB of ram.

Power supply is a bit of a problem. RTX 4070 is supposed to be up to a 285W card. Compared to the 200W GPU you have now, a 500W PSU is not going to be enough. (Also applies to the 4070Ti)

Really need to know the motherboard details and CPU cooler to suggest a CPU. 13th gen is a possibility.

10% is not really an accurate figure, it depends on how you are measuring performance.

In pure compute you are adding 2 P cores and 4 E cores, so in P cores alone you have a 33% increase, not to mention the 4 e cores which together are about as fast as a 6th or 7th gen i5.


Get to the BIOS to see what board you have, but you should get used to opening the computer if you are planning this level of upgrade.

Download and install CPU-Z and you should be able to get the model of the board.

Some good answers above ^^^ This is the way!

Thanks for good advices! I would probably need to change plan and go for another pc, as the pre build Acer would struggle to fit a bigger psu as i have been told by the store.
I would need help with this build for sure.

So if i order a custom build and add 750w psu and as i understand it would preform just as good in my use as a 1440p or 4K then it wont be noticable differences to still go with i5 12400 to save money? Or could we talk about less fps?
Aiming for 60fps in 4K, 120 would be a bonus but not a must for me.

What if i want to upgrade it to 4080 later at a time would i get just as high details in games running same 4K as i went with a more expensive cpu then i5 12400 12th gen?

Either processor should give you 60 FPS in 99% of games. @4K resolution the video card is going to be the limiting factor as to how high you can turn up the in game settings.

EDIT I would never buy a F processor just incase you have video card problems.

Couldn't agree more about F series chips. The on-board can just be a life saver.

For gaming, the i5 would handle a 4080 no problem, and probably then next few generations as well.
Of course you would get less fps, but it would be very minimal, less than 5% at 4K. maybe about 10% in most games in 1080p.
And yes, a 750w psu would be minimum for a 4070 build.
