Towards the end of last year, AMD launched its Ryzen 5000 CPUs, snatching the gaming crown from Intel after three (2 and a half) generations of Zen. Featuring an IPC boost of 19%, higher boost clocks, and wider core complexes, we’re looking at generational gains ranging from 20-35%, especially in gaming workloads. You can read our architectural deep-dive of the Ryzen 5000 CPUs and the Zen 3 core here. We compared the inter-core and cache latency/bandwidth of Matisse and Vermeer and got some very interesting results.
In this post, we will be comparing the $299 (now $279) Ryzen 5 5600X against the now similarly priced Ryzen 7 3700X which packs two additional cores, and decide whether it’s better to opt for more cores or a higher IPC/boost clock combo for gaming.
Test Bench
- Motherboard: ASRock X570 Taichi
- Memory: Trident Royal Z 8GB x2 @ 3733MT/s (CL16)
- Cooler: NZXT Kraken X73: 360mm (Special thanks to NZXT for providing the AIO cooler)
- GPU: NVIDIA RTX 2080 Ti
- PSU: Corsair HX1000i
AMD Ryzen 5 5600X vs Ryzen 9 5900X: Specifications
| Specs | Ryzen 5 5600X | Ryzen 5 3600X | Ryzen 7 3700X | Ryzen 9 5900X |
|---|---|---|---|---|
| Cores/Threads | 6/12 | 6/12 | 8/16 | 12/24 |
| Base Clock | 3.7GHz | 3.8GHz | 3.6GHz | 3.7GHz |
| Boost Clock | 4.6GHz | 4.4GHz | 4.4GHz | 4.8GHz |
| L3 Cache | 32MB | 32MB | 36MB | 64MB |
| TDP | 65W | 95W | 65W | 105W |
| Price | $299 | $199 | $304 | $549 |
Out of the four processors that we’ll be testing, the Ryzen 9 5900X is the only one with a TDP of 105W. Despite using a high-end 360mm AIO cooler, the 5900X approached the 80-degree mark under heavy load. Technically, you can emulate the Ryzen 5 5600X by disabling one of the two CCXs on the 5900X but we decided to use the actual processors for the tests.
Ryzen 5 5600X vs Ryzen 7 3700X: Gaming Benchmarks
Ashes Escalation
We tested all the games at 1080p ultra and then 720p medium to avoid any GPU bottlenecks that may otherwise affect the results. In Ashes of the Singularity at 1080, both the CPUs produced nearly identical averages and mildly different lows. This is despite the fact that this is easily one of the most CPU-intensive games on the market.
Strangely, the Ryzen 5 5600X outperformed the 3700X as well as the 5900X with respect to the averages at 720p. In terms of the lows, the hex-core 5600X was once again faster than the older octa-core Ryzen part.
As you can see, the Ryzen 5 5600X reaches an average CPU load of 88% and a peak of 100%. The average thread utilization is also pretty high at 97%, with a minimum of 75%. The Ryzen 7 3700X, on the other hand, averaged a tad bit lower at 84%, with a minimum of 60% and a max of 100%. (ambien) The clock speeds for the latter are quite a bit lower here (by 500MHz) while the GPU utilization is roughly the same. This indicates that the delta here is primarily due to the IPC/single-threaded performance deficit between the two, despite the fact that Ashes is easily on the most heavily multi-threaded titles.
Assassins’ Creed Origins
Assassins’ Creed Origins produces very predictable results. Going from the hex-core 3600X to the octa-core 3700X yields less than a handful of frames. In a similar fashion, going from the 5600X to the 5900X pushes you up by just over 5 FPS at 720p. For reference, the overall CPU utilization for the Ryzen 5 5600X averaged close to 70% while the 3700X averaged just over 55%.
Assassins’ Creed Valhalla
At 1080p, Assassins’ Creed Valhalla runs into a GPU bottleneck with both the Ryzen 5 5600X and the 5900X posting similar figures when paired with the GeForce RTX 2080 Ti.
At 720p, although the GPU bottlenecks are removed and the 5900X rushes past the 5600X to an impressive 124 FPS (average) and 62 FPS (0.1 percentile FPS), the overall CPU usage remains rather poor, with the latter averaging just around 25% and the former staying just under 60%.
The Division 2
In The Division 2, the Ryzen 7 3700X barely outpaces the 3600X at 720p but falls behind at 1080p when it comes to the averages. The Ryzen 5 5600X is much faster than every other CPU tested, especially at lower resolutions.
Once again, the CPU utilization is more or less the same across the 5600X and 3700X, but the IPC/boost clock advantage puts the former ahead of the latter.
