Select videocard for UE4 (system requirements)

Development Platform & Builds

Hi guys.

My current config:
• Intel Core i3 2.93
• 8GB DDR3
• Radeon HD 5670

I really want to work with Unreal Engine 4, but with my config I cant feel comfortable in editor - too lof FPS even with editor scalable settings.

Here I see system requirements for UE4

Here it is:
• Desktop PC or Mac
• Windows 7 64-bit or Mac OS X 10.9.2 or later
• Quad-core Intel or AMD processor, 2.5 GHz or faster
• NVIDIA GeForce 470 GTX or AMD Radeon 6870 HD series card or higher
• 8 GB RAM

So, looks like ,y only weak point is videocard.

I watched this table
http://radeon.ru/reference/cardtable/
and see that Radeon 6870 HD is a quite low.

So here is my question:
If I buy some inexpensite videocard in R7 line, for example Radeon R7 240 - can I bee sure that I will have good FPS in editor for a quite normal work.

Videocard needed only for work with UE4, I’m afraid to spend money for nothing :frowning:

That card is only a 128-bit graphics card. It is also a DDR3 card, whereas 5670 is DDR5.
All in all, benchmarks seem to indicate that the R7 240 and the HD 5670 are approximately equal in performance, with the HD 5670 being slightly faster.
I recommend spending significantly more on a card if you want to run the editor comfortably with complex scenes. Something like a GeForce GTX 750 would be about twice as fast as the 5670; a GTX 760 would be four times or better.

Also, are you SURE the graphics card is the problem? The Core i3 is only a dual-core CPU (it may have four hardware threads through hyperthreading, depending on model, but it’s a dual-core chip.) If the CPU is pegged at 100% when you run the editor, the CPU is the problem, not the GPU.

You need to buy a quad CPU and GPU with at least 2GB of video memory if not 4GB. This will get you a good frame rate.

Core i3s are very weak dual cores.
