Fivem

Resolution Scaling

The measured FPS data for Fivem with the Intel Core i5-9400 and AMD Radeon RX 6600 shows a clear and predictable pattern: performance degrades significantly as resolution increases, but the rate of decline varies sharply by settings preset. At 1080p Low, the combo produces 149.1 FPS, which drops to 95 FPS at 1440p Low (a 36% reduction) and further to 54.4 FPS at 4K Low (a 43% reduction from 1440p). This steep scaling at Low settings indicates that the GPU is being pushed harder as pixel count grows, but the CPU is still feeding frames efficiently at lower resolutions.

The picture changes at High settings. Here, 1080p yields 93 FPS, 1440p drops to 58 FPS (a 38% reduction), and 4K falls to 32.2 FPS (a 44% reduction from 1440p). The consistency of these percentage drops across settings suggests that the limiting component shifts from CPU-bound at 1080p Low to GPU-bound at 4K Ultra. At 4K Ultra, the combo manages only 29 FPS, which is below playable thresholds for most users. The gap between Low and Ultra at 4K is stark: 54.4 FPS versus 29 FPS, a 47% penalty for maxing out settings.

The data indicates that the RX 6600's 8 GB of GDDR6 memory and 224.0 GB/s bandwidth become strained at 4K, particularly with higher presets. Meanwhile, the i5-9400's six cores and six threads, with a boost clock of 4.10 GHz, appear sufficient to avoid bottlenecking at 1080p, where the GPU is the primary constraint. Resolution scaling is therefore smooth but punishing: dropping from 1080p to 1440p costs roughly 37% of FPS on average across presets, while moving from 1440p to 4K costs an additional 43% on average. This combo is best suited to 1080p or 1440p gaming, with 4K reserved for Low or Medium settings if frame rate is prioritized.

FAQ

CPU Role

The Intel Core i5-9400 is a six-core, six-thread processor from the Coffee Lake generation, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. Its 9 MB of shared L3 cache and dual-channel DDR4 memory support (42.7 GB/s bandwidth) are modest by modern standards, and its 50th percentile ranking among all CPUs reflects its mid-range position. In Fivem, benchmark results indicate that the CPU's role shifts depending on resolution and settings.

At 1080p Low, the combo achieves 149.1 FPS, which is near the upper limit of what this CPU can feed, given its six threads. The fact that FPS drops to 93 at 1080p High (a 38% reduction) suggests that the GPU is taking on more work, but the CPU's single-core performance (Cinebench R23 single-core score of 1125) is sufficient to avoid a hard bottleneck. At 1440p and 4K, the CPU's influence wanes as the GPU becomes the primary constraint. For instance, moving from 1080p High to 1440p High reduces FPS from 93 to 58, a 38% drop that is almost entirely attributable to GPU load.

The i5-9400's six threads are adequate for Fivem's multiplayer environment, but the data shows that higher settings increase GPU demand faster than CPU demand. The processor's avgBenchmarkScore of 2305 places it within 0.6% of the Intel Xeon E-2134 (2295) and 0.2% of the Intel Core i3-10305 (2300), indicating that it performs similarly to those chips in synthetic tests. In real-world Fivem results, the CPU's 4.10 GHz boost clock helps maintain frame times, but the lack of hyper-threading limits its ability to handle heavy background tasks alongside the game.

Settings Recommendations

Based on the measured FPS rows, the Medium preset offers the best balance of visual quality and performance across all resolutions. At 1080p Medium, the combo delivers 116.4 FPS, which is 22% lower than Low (149.1 FPS) but 66% higher than Ultra (70.3 FPS). This makes Medium the sweet spot for high-refresh-rate monitors at 1080p. At 1440p Medium, the combo achieves 75.8 FPS, which remains above 60 FPS and is only 20% lower than Low (95 FPS). This is the recommended preset for 1440p gaming, as it preserves fluidity while improving visual fidelity over Low.

For 4K, the data suggests using Low settings (54.4 FPS) as the only viable option for near-60 FPS gameplay. Medium at 4K drops to 45 FPS, which may be acceptable for less demanding users but falls short of smoothness standards. Ultra settings are not recommended at any resolution: at 1080p Ultra (70.3 FPS), the FPS is still playable, but the 53% penalty from Low (149.1 FPS) is not justified by visual gains. At 1440p Ultra (44.5 FPS) and 4K Ultra (29 FPS), the experience is compromised. The High preset sits between Medium and Ultra: 93 FPS at 1080p, 58 FPS at 1440p, and 32.2 FPS at 4K. For most users, Medium provides the best experience, with Low reserved for maximum frame rates and Ultra only for static screenshots.

How This Combo Ranks

The Intel Core i5-9400 + AMD Radeon RX 6600 combination ranks 1429 out of 1792 tested combos in Fivem, placing it in the 20th percentile of all configurations. This low-mid ranking is reflective of the hardware's age and tier: the CPU sits at the 50th percentile among all CPUs, while the GPU sits at the 69th percentile among all GPUs. The combo's rank is dragged down by the CPU's limited thread count and the GPU's 8 GB VRAM, which becomes a constraint at higher resolutions.

Compared to other tested combos, this pairing is outclassed by systems with newer CPUs and higher-tier GPUs, but it outperforms configurations with older or weaker components. The i5-9400's nearest CPU rivals—the Intel Core i3-10305, Intel Core i3-1125G4, and Intel Xeon E-2134—all have average scores within 0.4% of the i5-9400, indicating that this CPU is competitive with those chips in synthetic benchmarks. The RX 6600's nearest GPU rivals, including the RTX 3060 Ti (0.5% delta), show that the GPU is well-matched with mid-range competitors. However, in Fivem specifically, the combo's rank of 1429 suggests that other tested combos with similar or slightly better hardware achieve higher FPS, particularly at 1080p where the CPU's six threads may limit performance.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all presets. Low settings produce 149.1 FPS average, Medium produces 116.4 FPS, High produces 93 FPS, and Ultra produces 70.3 FPS. The progression from Low to Ultra shows a 53% reduction in FPS, with the largest single-step drop occurring between Medium and High (23.4 FPS) and between High and Ultra (22.7 FPS).

At 2560x1440, the FPS figures are 95 (Low), 75.8 (Medium), 58 (High), and 44.5 (Ultra). The drop from Low to Medium is 19.2 FPS (20%), from Medium to High is 17.8 FPS (23%), and from High to Ultra is 13.5 FPS (23%). This shows consistent scaling penalties as settings increase.

At 3840x2160, the combo manages 54.4 FPS (Low), 45 FPS (Medium), 32.2 FPS (High), and 29 FPS (Ultra). The gap between Low and Medium is 9.4 FPS (17%), between Medium and High is 12.8 FPS (28%), and between High and Ultra is 3.2 FPS (10%). The Ultra preset at 4K is the lowest measured result, representing a 81% reduction from the 1080p Low peak of 149.1 FPS.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a Navi 23 chip, featuring 1792 shading units, 112 texture mapping units, and 64 ROPs. It operates at a base clock of 1626 MHz and a boost clock of 2491 MHz, with a game clock of 2044 MHz. The 8 GB of GDDR6 memory on a 128-bit bus provides 224.0 GB/s of bandwidth, which is adequate for 1080p and 1440p gaming but becomes a limiting factor at 4K. The GPU's 69th percentile ranking among all GPUs and its avgBenchmarkScore of 25235 place it in the mid-range tier, just 0.5% behind the RTX 3060 Ti in average score.

In Fivem, the GPU's role is evident in the resolution scaling data. At 1080p Low, the GPU produces 149.1 FPS, but at 4K Low, it drops to 54.4 FPS—a 64% reduction that highlights the GPU's bandwidth and compute limits. The FP32 performance of 8.928 TFLOPS and texture rate of 279.0 GTexel/s drive the frame rates, but the 128-bit memory bus struggles with 4K workloads. The GPU's pixel rate of 159.4 GPixel/s is sufficient for 1080p, but the increasing pixel count at 1440p and 4K causes the FPS drops observed in the data. The RX 6600's 8 GB VRAM is not exceeded at 1080p or 1440p, but at 4K Ultra, the memory capacity and bandwidth become strained, contributing to the 29 FPS result. The GPU's boost clock of 2491 MHz helps maintain performance in lighter scenes, but sustained 4K gaming requires lower settings to avoid dipping below 60 FPS.
