Published this weekend was a 25-way Linux graphics card comparison for the newest major Linux game release, A Total War Saga: Thrones of Britannia, that was released natively for Linux days ago by Feral Interactive and ported from Direct3D to Vulkan in the process. As a result of premium requests, here are some additional tests for this Linux game when comparing the performance on Intel Core i7 8700K and Ryzen 7 2700X processors.

Similar to past Core i7 8700K vs. Ryzen 7 2700X Linux gaming benchmarks, this is seeing how the performance differentiates between these enthusiast/gaming Intel and AMD processors. With each system, an AMD Radeon RX Vega 64 and GeForce GTX 1080 were tested.

The latest drivers were used on each platform and testing happened with Ubuntu 18.04 LTS x86_64 on the Linux 4.17 kernel. Both CPUs were running at stock speeds, utilizing DDR4-3400 memory, and set to use the performance CPUFreq/P-State frequency scaling governor.

This Thrones of Britannia comparison is very straight-forward so let's get to the numbers. Following the FPS and frame time measurements are also some performance-per-dollar metrics looking at the cost of the combined CPU/GPU combinations. All of the benchmarks were facilitated using the Phoronix Test Suite.

First up was 1080p with low quality settings. The Core i7 8700K was faster than the Ryzen 7 2700X with both graphics cards tested. The RX Vega 64 was 3% faster with the Intel CPU while the GTX 1080 was 11% faster with the i7-8700K over the Ryzen 7 2700X.

What is interesting to note as well is the peak frame time being much higher with the Ryzen CPU too. The peak frame time being higher on Ryzen was found with both graphics cards tested. The RX Vega 64 had a peak frame time of 285 ms on the Intel CPU while on the Ryzen 7 2700X it drifted up to 424 ms, a similar margin was found with the GTX 1080 testing too.

When running at low quality settings at 1440p, the average frame-rates were similar between the Core i7 and Ryzen 7 processors, but there remained a noticeably higher peak frame time with the AMD Ryzen CPU under both of the graphics cards tested.

When moving up to high quality settings at 1080p, the Core i7 8700K was running much better than the Ryzen 7 2700X: the RX Vega 64 on the Intel CPU was in fact faster than the GTX 1080 on the AMD CPU. The RX Vega 64 was 16% faster with Intel and 18% faster with the NVIDIA GTX 1080 on Intel. The trend also continued with a higher peak frame-time on the Ryzen CPU while the average frame-time was about a 1ms difference.

At 1440p with high quality settings, the Core i7 8700K was still favored over the Ryzen 7 2700X, but by a lesser extent. The GTX 1080 was 12% faster here with the Intel CPU over AMD.

At 1080p with extreme settings, the average frame-rates were similar between the Ryzen 7 2700X and Core i7 8700K with both of the tested graphics cards. However, the maximum frame-rate was higher with Intel CPUs with the GTX 1080 topping out at 122 FPS on the i7-8700K but only 100 FPS with the Ryzen 7. Meanwhile, when it came to frame-times, the Ryzen 7 CPU continued having the highest peak latency on both of the graphics cards tested.

1440p with extreme quality settings had similar average frame-rates between the competing desktop CPUs but with the Intel CPU allowing for a higher peak frame-rate while the Ryzen 7 CPU also had a noticeably higher peak frame time.

Lastly is a look at the performance-per-dollar on these results. The current pricing comes in at $319 USD for the Ryzen 7 2700X, $349 for the Core i7 8700K, the GeForce GTX 1080 Founders Edition for $549, and the Radeon RX Vega 64 at $599.

The combination yielding the best value for Thrones of Britannia on Linux with this new Vulkan-powered game was the Intel Core i7 8700K with GeForce GTX 1080.
