Unreal Engine 5 Matrix City Sample PC Analysis: The Cost of Next-Gen Rendering

- Very CPU single thread limited
- 2060 Super able to get 30fps 4k TSR from 1080p Internal
- 2060 Super and 3080/3090 hardware lumen performs 7% slower than software lumen
- 6800XT hardware lumen performs 17% slower than software lumen
- 6800XT 3% slower than 3080 at 4k and at Epic settings, 6800XT is 10% slower than 3080 which is a reversal from UE5 Early Access demo where 6800XT was 10% ahead
- AMD Ray Tracing has glitches vs Nvidia so it's not 1:1 comparison
- PS5 either running sub 1080p or TSR mode is worse than on PC to help with the demo
- Console reduce motion blur resolution to quarter resolution
- Shadows on PS5 half resolution

I am surprised how CPU limited this demo really is vs GPU. Even a 2060 Super is able to get pretty good results all things considering where as the 3600 CPU is getting trashed but so are console CPUs. It seems that most of the CPU issues are coming from enabling hardware Ray Tracing as CPUs are currently doing BVH calculations along with being heavily single threaded. But I suspect by the time it ships, most of the issues will be ironed out.

AMD Ryzen 7 5800X3D Zen3 processor with 3D V-Cache is now available

I feel like UE5 is really going to show the limitations of older Zen 1/2 CPU's and Intel 10th and 11th gen CPU's very rapidly.

Core clocks and cache is what this engine will love...

We need to remember that UE5 wasn't designed and built around Hardware Ray Tracing either, Lumen was originally a software-only ray tracing engine and the engine reflects that.

Seems the 5800X3D flew off shelves here, didn't even get a look in. Not that I would buy only an 8 core CPU anyway...


The Radeon 6400 has 75% of the hardware as the 6500XT, but half the power consumption, 25% lower price.
If you need a half height, low-powered GPU for a SFF or HTPC, it's not bad... But it's also no better value-for-dollar wise than the 6500XT... The video decode is likely the biggest screw up for that market, would be better off with a Polaris derived GPU.
