Intel i5 8400 running at 100% (alien.top)

Hey all I’m not super familiar with Intel chips so hoping someone might be able to give me some advice.

I’m pairing the above chip with a AMD RX6700 XT which sits around 60% usage.

When I boot games during the initial load they will freeze for 5ish seconds.

However my CPU is sat at 100% usage (both are while gaming) and I’m trying to understand if I have a bit of a bottleneck.

At the moment I have 16GB or RAM but that will be going to 32 tomorrow.

And I know the i5 is somewhat old but reading online it should still hold up pretty well.

All of this is playing COD which I know is a CPU heavy game.

Task manager also looks good in the respect of programmes using the CPU

Any advice would be great!

The i5 does still hold up pretty well, but it's only got six logical cores and no hyper threading. So it's not too hard to end up core limited, like you're seeing right now. Especially when you put a 6700 XT on it. Even if you weren't core limited, you'd likely be bottlenecking it via IPC limitations. You could go for a 8700K, which add hyper threading, but I would suggest getting an i9 9900K for the two extra cores and threads, as well as higher clocks. You might need to flash the BIOS to a newer version to run the 8th gen CPU in your board. If you don't want to go with the i9, I would suggest going with at least the 9700K, which has eight cores, with no hyper threading. Also, you'll likely need a cooler upgrade for any of those options.

"However my CPU is sat at 100% usage (both are while gaming) "

Sounds like a big cpu bottleneck.

its a 6 year old 2.8 ghz 6 core 6 thread cpu trying to play a game made for a modern console running an 8 core 16 thread cpu. your chip is way too weak, a good bit below the recomended settings

Yea your CPU is bottlenecking your GPU since it's pegged at 100%.

If you have a z board and decent cooler cheap option would be to grab a 8600k and overclock it to 5ghz, plus you can coin a bit back by selling the 8400. If you dont have a z board try and find a cheap 9700 for the extra cores

lol.. new cpu you will probably gain 80fps lmao

st there are budgets, wait for one, the 12gen i5 or 9gen i9 are fine if you pay like me the other day 300€ for z390 mobo 32 gb ddr4 3200 and i9 9gen k version. i saw last week other offer for an equal setup for 250.
