Is my OC FX-6300 bottlenecking my RX 480 1330mhz GPU

post #1 of 4
Thread Starter 
I recently built my first gaming pc, of which I had a tight budget but I wanted an rx 480 I found on sale newegg for only $200. When I put it togather, the fx 6300 was bottlenecking terribly, but since overclocking it from 3.5 ghz to 4.5 things have gotten better, but not the performance I would see on a benchmarking video with, say, rx 480 + i5 6600k. I am wondering though, is my cpu still holding back my GPU? In games like just cause 3 I have stuttering, although I dont know if this is because of my 8gb of ram, but in most games my GPU load is 100% and cpu around 50-80%. I just dont really know enough to officially answer this myself so someone please tell me.

GPU load at 100% is a good thing. So you still have CPU left to spare, but that CPU isn't very fast.

So say a game uses 3 of your 6 threads, you still have 3 threads left to spare, but it doesn't matter if the game your playing doesn't utilize it.
In this case you would want more single thread performance, and the FX series is severely lacking compared to a skylake i5 you mentioned.

So I guess to answer your question, yes it is bottlenecking but more-so due to how the game engine works, not because you are running out of CPU to use.

It's a loaded question. Your answer will be yes and no. In benchmarks you almost always see lower numbers than the newer Intel or AMD Ryzen systems. What resolution do you play at?

Yea sometimes the GPU load doesn't tell the whole story. You are likely bottlenecked a bit, or a lot depending on the game. If it becomes too bothersome, a r5-1400 + cheap am4 mobo + ddr4 ram is going to be your cheapest route.

Also, depending on your current cooling & Mobo, that 6300 could probably go further... like closer to 5ghz.
