Resolution Scaling

The measured FPS data for FiveM with the Intel Core i5-14600KF and NVIDIA GeForce RTX 5090 reveals a pronounced CPU-limited profile at lower resolutions, with the scaling pattern confirming that the GPU headroom is substantial until 4K. At 2560x1440 with Low settings, the combo delivers 251.7 FPS, but dropping to 1920x1080 at Low pushes that to 374.9 FPS — a 48.9% increase. This disproportionate gain from resolution reduction is the classic signature of a CPU-bound scenario, where the RTX 5090 is nowhere near its rendering ceiling.

Moving from 2560x1440 to 3840x2160 at Low settings, the frame rate falls from 251.7 to 140.5 FPS, a 44.2% reduction. This is a much steeper drop than the pixel-count increase alone would suggest, indicating that at 4K the workload shifts decisively toward the GPU. The same pattern holds across all settings: at Medium, the 1440p-to-4K transition drops from 200.6 to 111.6 FPS (-44.4%), and at High from 155.8 to 86.9 FPS (-44.2%). The consistency of this ~44% penalty across three different quality presets strongly implies that the scaling bottleneck at 4K is the GPU's raw throughput, not any single setting.

At 1920x1080, the data shows extreme CPU saturation. The gap between Low (374.9 FPS) and Ultra (184.2 FPS) is 190.7 FPS, which is a 50.9% performance penalty solely from raising quality. Compare that to the 4K gap between Low (140.5) and Ultra (68.8), which is also large at 71.7 FPS but represents a smaller 51.0% relative drop. The near-identical relative penalties suggest that FiveM's Ultra preset imposes a consistent load overhead, but the absolute numbers tell the real story — at 1080p the CPU is the limiting component, while at 4K the GPU becomes the primary constraint.

GPU Role

The RTX 5090's 32 GB of GDDR7 memory on a 512-bit bus delivers 1.79 TB/s of bandwidth, and in FiveM this capacity is far beyond what the game demands at any measured setting. The data shows that even at 4K Ultra, the combo produces 68.8 FPS, which is playable but not the triple-digit figures seen at lower resolutions. The GPU's boost clock of 2407 MHz and base of 2017 MHz, combined with 21,760 shading units, 176 ROPs, and a 104.8 TFLOPS FP32 throughput, suggest a card that should theoretically crush this title — yet the 4K results indicate a ceiling.

At 3840x2160, the scaling from Low (140.5 FPS) to Medium (111.6 FPS) costs 28.9 FPS, and from Medium to High (86.9) another 24.7 FPS. These are substantial per-step penalties, and the step from High to Ultra (68.8) adds a further 18.1 FPS loss. The diminishing returns pattern is typical of GPU-bound rendering where each quality tier adds measurable pixel and shading work. The 4K Ultra result of 68.8 FPS is the lowest in the entire measured set, confirming that the RTX 5090 is being fully exercised only at the highest resolution and preset combination.

The GPU's passmark G3D score of 39,650 and 3DMark Steel Nomad DX12 score of 14,411 place it in the 94th percentile of all GPUs, and benchmark results indicate it sits 0.1% ahead of the RTX 5090 D and 1.3% ahead of the AMD Radeon PRO W6600 in average score. However, in FiveM specifically, the GPU's 32 GB VRAM is effectively a non-factor — the game's measured frame rates at 1080p and 1440p are far more dependent on CPU throughput, as evidenced by the massive FPS jumps when lowering resolution.

CPU Role

The Intel Core i5-14600KF is the dominant factor in this combo's FiveM performance, and the data makes this unambiguous. With 14 cores, 20 threads, a 3.50 GHz base clock, and 5.30 GHz boost clock, this Raptor Lake-R chip produces a Cinebench R23 multi-core score of 32,889 and single-core score of 4,643. The single-core strength is particularly relevant for FiveM, which is a multiplayer modification framework that typically relies on fewer threads for the main game loop.

The evidence for CPU limitation is overwhelming. At 1920x1080 Low, the combo achieves 374.9 FPS, but at 2560x1440 Low it drops to 251.7 FPS — a 32.9% decrease from a 77.8% pixel increase. If the GPU were the limiting factor, the FPS drop would be closer to the pixel count ratio. Instead, the relatively smaller FPS loss indicates the CPU is holding performance back even at 1440p. The 1080p results across all settings — 241.3 High, 299.2 Medium, 374.9 Low — all exceed what a GPU-bound scenario would produce, confirming the processor is the ceiling.

The CPU's passmark multi-thread score of 38,697 and single-thread score of 4,273 place it in the 93rd percentile of all CPUs. Its nearest rival, the Intel Core i5-14600K, is just 0.4% behind in average benchmark score, while the AMD Ryzen 9 5950X is 0.6% behind and the Intel Xeon Gold 5318H is 1.4% behind. In FiveM, the 5.30 GHz boost clock is likely the key differentiator, as the game's frame pacing at high FPS depends on rapid single-thread execution.

FAQ

Q: Why does the FPS drop so much from 1080p to 4K at Low settings?

A: At 1920x1080 Low the combo produces 374.9 FPS, but at 3840x2160 Low it falls to 140.5 FPS. The 4K resolution increases pixel count by 4x, and the data shows a 62.5% FPS reduction, indicating the GPU becomes the primary bottleneck at 4K whereas the CPU limits at 1080p.

Q: Is the RTX 5090's 32 GB VRAM necessary for FiveM?

A: The measured results show no evidence that VRAM capacity affects performance in this title. The 32 GB GDDR7 memory with 1.79 TB/s bandwidth is far beyond FiveM's requirements, as frame rates are instead dictated by CPU speed at lower resolutions and GPU compute at 4K.

Q: What is the best resolution for maximizing frame rate with this combo?

A: 1920x1080 with Low settings delivers the highest measured average at 374.9 FPS. For balanced quality, 2560x1440 at Medium produces 200.6 FPS, which is likely the sweet spot for high refresh rate displays.

Q: How does the i5-14600KF compare to its closest CPU rivals?

A: The i5-14600KF's average benchmark score of 49,367 is 0.4% higher than the i5-14600K, 0.6% higher than the Ryzen 9 5950X, and 1.4% higher than the Xeon Gold 5318H, though these are synthetic benchmarks rather than game-specific measurements.

Q: Why is the 4K Ultra FPS so much lower than 1080p Low?

A: The 4K Ultra result of 68.8 FPS versus 1080p Low's 374.9 FPS represents an 81.7% reduction. This combines the GPU workload increase from 4K resolution with the additional shading and texture demands of the Ultra preset, pushing the RTX 5090 to its limits.

Q: Does the CPU or GPU matter more for FiveM performance?

A: The data strongly indicates the CPU is the primary factor at 1080p and 1440p, as evidenced by the large FPS gains when lowering resolution. At 4K, the GPU becomes the limiting component, with the RTX 5090's throughput capping results around 140 FPS at Low settings.

Measured FPS Breakdown

At 1920x1080, the results span from 184.2 FPS at Ultra to 374.9 FPS at Low. The Medium preset delivers 299.2 FPS, while High sits at 241.3 FPS. The step from Low to Medium costs 75.7 FPS, from Medium to High costs 57.9 FPS, and from High to Ultra costs 57.1 FPS. These are substantial per-tier penalties, and the fact that even Ultra maintains 184.2 FPS indicates the CPU is still providing enough throughput at 1080p.

At 2560x1440, the pattern is similar but with lower absolute numbers. Low produces 251.7 FPS, Medium 200.6 FPS, High 155.8 FPS, and Ultra 123.8 FPS. The Low-to-Medium drop is 51.1 FPS, Medium-to-High is 44.8 FPS, and High-to-Ultra is 32.0 FPS. The diminishing per-step losses suggest that at 1440p, the GPU begins to share the bottleneck with the CPU, particularly at higher settings.

At 3840x2160, the results are 140.5 FPS at Low, 111.6 FPS at Medium, 86.9 FPS at High, and 68.8 FPS at Ultra. The Low-to-Medium penalty is 28.9 FPS, Medium-to-High is 24.7 FPS, and High-to-Ultra is 18.1 FPS. The relatively smaller absolute gaps at 4K confirm that the GPU is the limiting factor here, as each quality tier adds similar relative workload but the frame rate floor is much lower.

Settings Recommendations

The measured data points to 2560x1440 at Medium as the optimal balance for this combo. At 200.6 FPS, it clears the 144 Hz refresh rate threshold comfortably while maintaining a quality level that is visually meaningfully higher than Low. The 1440p Medium result is 51.1 FPS lower than Low at the same resolution, but the visual uplift is substantial, and the frame rate remains well above competitive thresholds.

For users prioritizing maximum frame rate, 1920x1080 at Low delivers 374.9 FPS, which is the highest measured result in the entire dataset. This is the clear choice for esports-style play where every frame matters, though the visual compromise is significant. At 1080p Medium (299.2 FPS) the experience remains extremely smooth while adding moderate visual fidelity.

At 4K, the data suggests High (86.9 FPS) is the most sensible preset, as Ultra (68.8 FPS) offers diminishing visual returns for a 18.1 FPS penalty. The 4K Low result of 140.5 FPS is playable but visually barren for a title like FiveM, which benefits from higher quality settings for visibility. The 4K Medium result of 111.6 FPS is a reasonable compromise for users with 60-120 Hz 4K displays.

How This Combo Ranks

The Intel Core i5-14600KF + NVIDIA GeForce RTX 5090 combination ranks 6th out of 1,792 tested combos in FiveM, placing it in the top 0.3% of all configurations. This is an exceptional result, though not the absolute best — the rank indicates that a handful of other CPU-GPU pairings achieve higher measured frame rates in this specific game.

The ranking is particularly notable because the RTX 5090 is the highest-performing GPU in the dataset by percentile (94th), and the i5-14600KF is also strong (93rd percentile). However, FiveM's CPU sensitivity means that processors with even higher single-thread performance could potentially edge out this combo, despite the i5-14600KF's 5.30 GHz boost clock.

The data shows that this combo's 1080p Low result of 374.9 FPS is likely near the practical ceiling for the game's engine, and the 4K results are competitive but not class-leading. The 6th place ranking out of 1,792 combos means that only five other CPU-GPU pairings deliver higher average frame rates in FiveM, making this a top-tier configuration for the game. The combination of the i5-14600KF's strong single-core performance and the RTX 5090's massive throughput creates a well-rounded pairing that excels across all measured resolutions and settings.
