F1 2020 is the official video game of the 2020 Formula 1 and Formula 2 Championships developed and published by Codemasters. It is the thirteenth title in the Formula 1 series developed by the studio and was released on 7 July 2020 for pre-orders of the Michael Schumacher Edition and 10 July 2020 for the Seventy Edition on Microsoft Windows, PlayStation 4, Xbox One.

Engine: EGO. We test using the Ultra High preset, DX12 API.

The results from F1 2020 once again show a clear benefit to using an eGPU with an external monitor. The RTX 3060 Ti, for instance, is 10% faster on an external screen than it is using the integrated laptop display. Another way of putting it is that the RTX 3070, when using an external monitor, is only 4% slower than the RTX 3090 when that GPU is using the laptop screen.

Even then, at 1080p we are running into some fairly strong bottlenecking, which could be either the CPU or the fact that Thunderbolt 3 can only provide 4 PCIe lanes, but I'd suggest the issue is mostly likely a combination of those two factors. Either way, the bottleneck is clearly shown by the fact that the RTX 3090 is just 5% faster than the RTX 3080, delivering just 5 more frames per second on average. The RTX 3080, however, is still 16% faster than the RTX 3070; it’s a decent margin, but still not as large as we’d expect on a desktop system.

At 1440p, we’re not as limited as we were at 1080p, shown by the fact the RTX 3090 is now 8% faster than the RTX 3080. The RTX 3070 is also doing reasonably well, delivering 73FPS, which is 9% more than the RTX 3060 Ti, a number which isn’t too far off from what we’d expect to see from desktop performance.

As for 4K, we’re getting a decent experience from all four GPUs here. The RTX 3090 is stretching its legs now, beating out the RTX 3080 by 11%, which is pretty much the sort of margin we’d hope to see. The RTX 3080 also manages to outpace the RTX 3070 by 20%. Our previous testing shows, on a desktop, that margin would be closer to 30%, so we’re not seeing maximum performance scaling, but you’re still gaining a sizable chunk of extra performance from the RTX 3080 over the RTX 3070.
