GTX 750 or RX 460 - Bottleneck Issues

[Thaddeaus]

I have a Xeon X5450 and the GPUs that I can easily buy are GTX 750(not ti) and RX 460. The GTX 750 have less to no bottleneck caused by the X5450 compared to RX 460. Does that mean that if I buy RX 460, it will perform like a GTX 750 because it is bottlenecked by the CPU, so, I should buy the GTX 750? Please help. Thanks

how did you come by this information?

Sorry, I forgot to mention the bottleneck calculator online.

Xeon X5450 is a 4 core, non hyperthreaded Harpertown (Yorkfield) which is around the Core 2 Quad era of consumer processors, and is clocked at 3ghz.

 

I do not believe that it is overclockable, and I also believe that no matter what GPU you pair this with, the performance is going to be pretty bad, and neither one will be fully utilized.

unfortunately that tool is rather useless, it does not share reliable information.

 

As for GPU choice in this case, I think it matters little. You should go with the RX 460 if you plan on using it down the line for a future upgrade, however the real problem is that the X5450 uses a motherboard that has no good upgrade path, so if you haven't built this already you should reconsider the CPU choice. The best upgrade possible for a motherboard like that is a Xeon X5492 which is pretty terrible by today's standards.

Thank you. I would consider the thought of future upgrade.

The RX 460 is a lot faster

 

that's not really how bottlenecking works

 

if your CPU is stuck at 30-60 fps in a given game, you can just turn up your GPU settings so the game still looks better on the RX 460.

Correct.  Just crank SSAA or something similar, instantly GPU bottlenecked again.

 

Get the best GPU you can afford in your budget, the CPU/MB should be upgraded soonish though.  2nd gen i7 + H61 board will get you a platform that can push up to a 1060 without much struggle.

an overclocked i7 2600K should be able to do 60-100hz without an issue.

 

But I'd probably just go for a really cheap R5 1600 or R5 2600

I have such a setup, it struggles with keeping GPU usage up on an RX 470 on some games, in some cases only pushing 30-60 FPS.

 

R5-1600 has issues with the same games due to it being roughly the same on a per core basis.  It has better per clock performance, but lower clocks.

What games is it having issues with?

[KarathKasun]

Mechwarrior Online, Elite: Dangerous in some environments with ultra details, Elder Scrolls Online, etc.  Mostly games from the horrid days of multithreaded programming.

RX 570 4gig is your best option if you overclock your X5450 I run mine at 3.6 ghz runs fortnite at 75fps epic settings Forza is good for 60 FPS have also tried 750 and 1050 GTX TI cards the 570 is superior especially if you have a free sync monitor
