Fortnite

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 5070 combination delivers a highly capable Fortnite experience, with performance scaling predictably across resolutions and settings. The data shows a system that can push high refresh rates at 1080p and 1440p, while 4K Ultra remains a demanding target. This analysis breaks down the CPU and GPU contributions, contextualizes the combo’s ranking, and answers common questions based on measured results.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, built on a 4 nm process at TSMC. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, drawing a 65 W TDP. In synthetic benchmarks, its multi-threaded performance is solid, with a Cinebench R23 multi-core score of 20851 and a single-core score of 2943. The 3DMark 16-thread score of 6091 and max-thread score of 6165 indicate that the processor scales well with additional threads, though the difference between these two scores is minimal.

The CPU’s role in Fortnite becomes evident when examining frame rates at lower resolutions and settings. At 1080p with Low settings, the combo achieves 362.8 FPS, which is a massive jump from the 199.9 FPS seen at 1080p High. This suggests that at Low settings, the GPU is not the primary limiter, and the CPU’s ability to feed frames quickly is being tested. The Ryzen 5 8400F’s high boost clock and efficient architecture help it keep up with the RTX 5070’s output. However, at 4K Ultra, the frame rate drops to 42.5 FPS, indicating that the GPU becomes the bottleneck as resolution increases. The CPU’s 16 MB of shared L3 cache and 83.2 GB/s of memory bandwidth are sufficient for Fortnite’s demands, as the game is not heavily cache-dependent. The processor ranks in the 82nd percentile among all CPUs, with an average benchmark score of 25064, placing it nearly identical to the AMD Ryzen 7 2700X (deltaPct 0) and slightly ahead of the AMD Ryzen 5 7500F (deltaPct 0.3).

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture, featuring 12 GB of GDDR7 memory on a 192-bit bus, providing a bandwidth of 672.0 GB/s. Its base clock is 2325 MHz with a boost clock of 2512 MHz, and it draws a 250 W TDP. The GPU’s raw compute power is substantial, with FP32 performance rated at 30.87 TFLOPS and a pixel rate of 201.0 GPixel/s. In synthetic tests, it scores 29137 in Passmark G3D and 5077 in 3DMark Steel Nomad DX12, placing it in the 83rd percentile among all GPUs with an average benchmark score of 41687.

In Fortnite, the GPU’s performance is the dominant factor at higher resolutions and settings. At 4K High, the combo produces 66.9 FPS, but dropping to 4K Low increases this to 124.7 FPS, showing how the GPU’s workload scales with settings. The 12 GB VRAM is sufficient for Fortnite at all tested settings, as the game is not particularly VRAM-hungry. The RTX 5070’s nearest rival, the NVIDIA GeForce RTX 3090, has a deltaPct of 0.6, meaning the RTX 5070 is slightly ahead in average benchmark scores. The GPU’s high boost clock and memory bandwidth are key to maintaining high frame rates, especially at 1440p where it achieves 228.9 FPS at Low settings. The data indicates that the RTX 5070 is never the limiting factor at 1080p, as the CPU-bound scenarios show, but it becomes the primary constraint at 4K Ultra.

How This Combo Ranks

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 5070 combination ranks 318th out of 1564 tested combos in Fortnite, placing it in the top 20% of all configurations. This ranking reflects a balanced pairing where neither component drastically bottlenecks the other at typical gaming resolutions. The combo’s performance at 1440p High (129.8 FPS) and 1080p High (199.9 FPS) shows it can handle competitive play with high refresh rates. However, the ranking is not near the top, as more powerful CPUs or GPUs would push higher scores.

The data suggests that the combo is well-matched for 1440p gaming, where the GPU is fully utilized without being overwhelmed. At 1080p, the CPU’s single-thread performance becomes more relevant, and the Ryzen 5 8400F’s 3DMark single-thread score of 951 indicates it can handle the game’s physics and draw calls. The ranking of 318 out of 1564 is respectable, but it indicates that there are many combos with higher performance, particularly those with higher-end CPUs like the AMD Ryzen 7 2700X, which matches the 8400F’s average score but may have different in-game characteristics. The combo’s percentile rankings for the CPU (82) and GPU (83) are nearly identical, reinforcing the idea that this is a balanced system.

FAQ

Q: What is the maximum average FPS this combo achieves in Fortnite?

A: The highest average FPS recorded is 362.8 at 1080p with Low settings. The next highest is 256.5 at 1080p Medium, showing a significant drop when settings are increased.

Q: How does the combo perform at 4K resolution?

A: At 4K with Ultra settings, the average FPS is 42.5, which is below the 60 FPS threshold for smooth gameplay. Lowering settings to High improves this to 66.9 FPS, and at Low settings, it reaches 124.7 FPS.

Q: Is the CPU or GPU more important for Fortnite performance?

A: The data shows that at 1080p Low, the CPU is the limiting factor, as the frame rate of 362.8 FPS is extremely high. At 4K Ultra, the GPU becomes the bottleneck, with the frame rate dropping to 42.5 FPS. The balance shifts based on resolution and settings.

Q: How does this combo rank compared to other tested configurations?

A: This combo ranks 318th out of 1564 tested combos. The CPU and GPU both sit in the low 80s percentile among their respective categories, indicating a balanced but not top-tier pairing.

Q: What is the frame rate difference between 1080p and 4K at High settings?

A: At 1080p High, the average FPS is 199.9, while at 4K High, it drops to 66.9. This is a reduction of approximately 66.5%, showing the heavy impact of resolution on performance.

Q: Does the combo support high refresh rate monitors at 1440p?

A: Yes, at 1440p with Medium settings, the average FPS is 165.3, which exceeds the 144 Hz refresh rate common on many monitors. At Low settings, it reaches 228.9 FPS, which is suitable for 240 Hz displays.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance scaling as resolution increases. At 1080p, the combo averages 362.8 FPS on Low, 256.5 FPS on Medium, 199.9 FPS on High, and 129.4 FPS on Ultra. Moving to 1440p, these numbers drop to 228.9, 165.3, 129.8, and 81.1 FPS respectively. At 4K, the averages fall further to 124.7, 85.2, 66.9, and 42.5 FPS. The percentage drop from 1080p to 4K at High settings is from 199.9 FPS to 66.9 FPS, a decrease of 66.5%. At Low settings, the drop is from 362.8 FPS to 124.7 FPS, a decrease of 65.6%.

This scaling indicates that the limiting component changes with resolution. At 1080p, the CPU’s ability to process game logic and draw calls is the primary constraint, as evidenced by the high frame rates that approach the CPU’s limits. At 4K, the GPU’s pixel throughput and memory bandwidth become the bottleneck, with the frame rates dropping to levels that suggest the GPU is working at full capacity. The GPU’s 672.0 GB/s bandwidth and 201.0 GPixel/s pixel rate are sufficient for 1440p gaming, but at 4K Ultra, the workload becomes too demanding, resulting in an average of 42.5 FPS. The data shows that this combo is best suited for 1080p and 1440p gaming, where it can deliver high refresh rates, while 4K gaming requires reduced settings to maintain playable frame rates.
