Fivem

The Intel Core i5-9400 and AMD Radeon RX 6600 XT combination ranks 1257th out of 1792 tested combos in Fivem, placing it in the lower-middle tier of the database. This rank reflects a pairing where the six-core, six-thread Coffee Lake processor, with its 2.90 GHz base and 4.10 GHz boost clocks, works alongside a RDNA 2.0 GPU that sits at the 71st percentile among all GPUs. The CPU itself lands at the 50th percentile, meaning the graphics card is comparatively stronger than the processor, a dynamic that shows up clearly in the measured frame rates across resolutions and settings. The combo's position is not about outright failure; rather, it suggests a system that can handle the game at moderate settings, but one that will struggle to maintain high refresh rates at higher quality presets.

FAQ

Q: What is the best resolution for this combo to achieve a 60 FPS average?

A: At 2560x1440 with High settings, the combo averages 66.5 FPS, which is the only 1440p preset to exceed 60 FPS. At 1920x1080, every preset except Ultra (75.6 FPS) exceeds 100 FPS, with Low reaching 160.4 FPS.

Q: How much faster is the RX 6600 XT than its nearest rival in synthetic benchmarks?

A: The RX 6600 XT has an average benchmark score of 27985, which is 0.1% higher than the NVIDIA GeForce GTX 980 Ti (27956) and 0.4% higher than the AMD Radeon R9 M395X (27883). It trails the NVIDIA GeForce RTX 3070 by 0.9%, which scores 28238.

Q: Does the CPU bottleneck the GPU at 1080p Low settings?

A: The data shows 160.4 FPS at 1920x1080 Low, which is the highest average in the entire measured set. This suggests the CPU can feed the GPU enough data to produce a very high frame rate, but the drop to 102.4 FPS at High indicates that the rendering load is shifting, and the CPU's six threads are likely becoming a limiting factor at higher presets.

Q: What is the FPS cost of moving from Low to Ultra at 4K?

A: At 3840x2160, the average FPS drops from 55.6 on Low to 28.8 on Ultra. This is a 26.8 FPS reduction, which represents a 48% loss in average frame rate when maxing out the settings.

Q: How does the CPU's multi-core performance compare to its closest rival?

A: The i5-9400 has an average benchmark score of 2305, which is 0.2% ahead of the Intel Core i3-10305 (2300) and 0.2% ahead of the Intel Core i3-1125G4 (2299). It is 0.6% behind the Intel Core i7-8809G (2319).

Q: Is the 8 GB VRAM on the RX 6600 XT sufficient for this game at 4K?

A: The measured results show a playable 38.1 FPS average at 3840x2160 High, which implies the 8 GB frame buffer is adequate for this title at that resolution and preset. The card's 256.0 GB/s memory bandwidth and 128-bit bus are sufficient to avoid a complete collapse in performance, though 4K Ultra drops to 28.8 FPS.

Settings Recommendations

The measured data points toward 2560x1440 High as the optimal balance for this combo, delivering a 66.5 FPS average that clears the 60 FPS threshold. This preset provides a smooth experience without pushing the system to its limits. At 1920x1080, the High preset (102.4 FPS) is the best choice for users with 100 Hz or 120 Hz monitors, as it offers a substantial visual upgrade over Low (160.4 FPS) while still maintaining a triple-digit frame rate. The Medium preset at 1080p (127.8 FPS) is a fallback for those who want a higher refresh rate headroom, but the step from Medium to High costs 25.4 FPS, which is a significant trade-off for visual fidelity.

At 1440p, the Medium preset (80.5 FPS) is a viable alternative for users who prefer smoother motion over maximum detail, but the jump to High (66.5 FPS) is only a 14 FPS loss and yields noticeably better image quality. The Ultra preset should be avoided at all resolutions; at 1080p it drops to 75.6 FPS, at 1440p it falls to 52.5 FPS, and at 4K it becomes unplayable at 28.8 FPS. For 4K users, the Low preset (55.6 FPS) is the only option that approaches playability, but even that falls short of 60 FPS, indicating that this resolution is not the combo's strength.

Measured FPS Breakdown

Starting at 1920x1080, the combo shows its strongest performance. The Low preset produces a 160.4 FPS average, which is the peak of the entire dataset. Moving to Medium drops the average to 127.8 FPS, a 20.3% reduction. The High preset delivers 102.4 FPS, representing a further 19.9% drop from Medium. Ultra is the most demanding at this resolution, yielding 75.6 FPS, which is 26.2% lower than High. The scaling from Low to Ultra at 1080p results in a 84.8 FPS spread, showing that the GPU has enough headroom to render the game at high speed when settings are lowered.

At 2560x1440, the frame rates begin to compress. The Low preset averages 104.7 FPS, which is still smooth. Medium brings this down to 80.5 FPS, a 23.1% drop. High follows at 66.5 FPS, another 17.4% reduction. Ultra drops to 52.5 FPS, which is 21.1% lower than High. The spread from Low to Ultra at 1440p is 52.2 FPS, narrower than at 1080p, indicating that the GPU is starting to become the primary bottleneck as pixel count increases.

Moving to 3840x2160, the performance falls off sharply. The Low preset averages 55.6 FPS, which is the only 4K preset above 50 FPS. Medium drops to 45.6 FPS, an 18.0% reduction. High yields 38.1 FPS, a 16.4% drop from Medium. Ultra bottoms out at 28.8 FPS, which is 24.4% lower than High. The total spread at 4K is 26.8 FPS, showing that the GPU is heavily taxed at this resolution, and the CPU's role becomes less significant as the render workload dominates.

GPU Role

The AMD Radeon RX 6600 XT is the star of this pairing, with its 8 GB of GDDR6 memory on a 128-bit bus providing 256.0 GB/s of bandwidth. The card's boost clock of 2589 MHz and game clock of 2359 MHz, built on the 7 nm RDNA 2.0 architecture with 2048 shading units, deliver a PassMark G3D score of 16461 and a 3DMark Steel Nomad DX12 score of 1804. These numbers place the GPU at the 71st percentile, and its average benchmark score of 27985 is nearly identical to the GTX 980 Ti, showing that it punches above its weight class in synthetic tests.

In Fivem, the GPU's role is decisive at higher resolutions. At 4K, the frame rate scales directly with the settings preset, from 55.6 FPS on Low to 28.8 FPS on Ultra, with a consistent drop of roughly 8-10 FPS per preset step. This behavior indicates that the GPU's compute throughput and memory bandwidth are the limiting factors, as the CPU is not able to compensate for the increased pixel workload. The 32 ray accelerators and DirectX 12 Ultimate support are present but do not appear to provide a measurable advantage in this title, as the measured FPS at 4K Ultra is still below 30 FPS.

The GPU's 10.60 TFLOPS of FP32 performance is enough to drive high frame rates at 1080p, but the card's 160 W TDP and PCIe 4.0 x8 interface suggest it is designed for mainstream systems rather than extreme overclocking. The benchmark results confirm this: at 1080p Low, the combo reaches 160.4 FPS, showing that the GPU can handle the game's engine with ease when settings are minimized. The bottleneck shifts to the CPU at lower resolutions, but the GPU remains the dominant component for image quality decisions.

Resolution Scaling

The data reveals a clear pattern of frame rate degradation as resolution increases, but the rate of degradation is not uniform. From 1920x1080 to 2560x1440 at High settings, the average FPS drops from 102.4 to 66.5, a 35.1% reduction. This is a significant drop, but it is expected given the 1.78x increase in pixel count. The scaling from 1440p to 4K at High is steeper: the average falls from 66.5 to 38.1, a 42.7% reduction, which aligns with the 2.25x pixel increase from 1440p to 2160p.

At Low settings, the scaling is more dramatic. The 1080p Low average of 160.4 FPS drops to 104.7 FPS at 1440p, a 34.7% decrease, and then to 55.6 FPS at 4K, a further 46.9% decrease. This suggests that at Low settings, the CPU is still able to keep up with the GPU at 1080p, but by 1440p the GPU's pixel throughput becomes the limiting factor, and at 4K the GPU is fully saturated. The Ultra preset shows the least proportional scaling: 75.6 FPS at 1080p, 52.5 FPS at 1440p (a 30.6% drop), and 28.8 FPS at 4K (a 45.1% drop). This indicates that at Ultra, the GPU is already working near its maximum capacity even at 1080p, so the resolution scaling has a smaller relative impact.

The limiting component shifts based on resolution and settings. At 1080p Low and Medium, the CPU's six threads are likely the primary constraint, as the frame rates exceed 120 FPS and the GPU has ample headroom. At 1080p Ultra and all 1440p presets, the GPU becomes more influential, with the frame rates hovering between 52.5 and 104.7 FPS. At 4K, the GPU is unequivocally the bottleneck, as even the Low preset fails to reach 60 FPS. This analysis shows that the combo is best suited for 1080p gaming, acceptable for 1440p with settings compromises, and not viable for 4K beyond the lowest quality preset.
