I5 8400 bottleneck?

Solution


Yeah, this is GTA V maxed out settings at 1080P on my system, GTX 1080 FTW2 and i7 7700K as an example.

Any CPU can bottleneck any GPU. Just depends on your performance vs visual quality expectations and the types of applications or games being run and the conditions they are being run in.

What are you going t be doing with the i5 8400 and the GTX1050?
 


You would have to disable 5 cores then drop the resolution way down under 800x600 for that to happen and even then maybe not as the GTX 1050 really isn't that powerful of a card.

I did that experiment with both my i7 870 machine with a RX 480 and i7 7700K with GTX 1080 to see what it would take to create a bottleneck.

His question is vague, We don't know what he will be doing with the system. If he is using it for gaming, most modern games are limited by the GPU rather than the CPU. Unless he is planning on playing CPU intensive games.
1 The most CPU Intensive Games:
1.1 Resident Evil 7:
1.2 Just cause 3:
1.3 Hitman:
1.4 Prey:
1.5 Tekken 7:
1.6 Call of Duty: Infinite Warfare Or Call of duty WW1
1.7 Rise of the Tomb Raider:
1.8 GTA 5:

But if you crank up the quality and textures and antialiasing on your favorite game, you're typically only burdening the GPU. Just as long as the CPU can keep feeding the GPU with stuff to do... if the CPU is too slow, then your GPU is sitting around waiting for things to do.
But for normal 1080p gaming, The core i7 8400 is a great gaming CPU able to handle a GTX 1050 or even a GTX 1060.

An i5 8400 would be better suited at a higher resolution. In 4k there is no way this cpu would bottleneck a 1080 ti. Not even close.
Buy the 8400. You'll be very pleased and will be fine for a number of years. Hopefully the game developers start making more use of the extra cores.

He is using a GTX 1050!!! can't do 4k with that.

How do you find it? Everyone is saying it could potentially bottleneck the 1080ti. But i feel it's the best bang for your buck

Dude if you just wanna game please note, the i5 8400 is faster than ryzen 2600 and all of the 1st gen ryzen lineup. Its faster than an i5 7600k overclocked to 4.8 ghz in most games. It has 1% and 0.1% frames above 60 fps in the most intense cpu limited games infact its 1% and 0.1% frames are better than 7700k in few games.

Get a cheap H310 motherboard and cheap 2666 MHz ram with decent timing that CPU (8400) can make your gaming dreams come true on budget.

That CPU can stretch you gtx 1050 2GB to max all the time.

I bet you're only getting GTX 1070 performance out of that 1080 TI with that CPU though.

I doubt that, i5 8400 is a full 6 core CPU. It beats an overclocked 7600k. That thing is very close to i7 7700 non-k in performance infact.

Actually he's right. The i5-8400 has enough gas in the tank to drive a 1080 TI, at very respectable frame-rates too. However, I do recommend the minimum resolution to be 2560 x 1440p, if choosing to do so; as that will force the GPU to be the bottleneck anyways.

My fps dips below 100fps in project cars 2 in 2560x1440 144hz with the graphic's set to high

Dips below 100 fps, running only a single GTX 1080? Well that sounds about right. You may want to step up to the 1080 TI if you want a higher minimum on 2560 x 1440p. The GTX 1080 can only achieve above 60-75 fps in 1440p. Only the 1080 TI can surpass 90+ FPS in 1440p.

I can get above 100fps, my cpu runs at 60 ish % but my gpu only runs at 79% an to the early 90% when racing in projrct cars 2.
