Fivem

# How This Combo Ranks

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 5090 D lands at rank 284 out of 3005 tested combos in Fivem, placing it in the top 9.5% of all configurations. This is a strong showing, but the ranking reveals an important story: the GPU is doing the heavy lifting, while the CPU holds back what would otherwise be a top-tier result. The i5-9400 sits at the 47th percentile among all CPUs, while the RTX 5090 D ranks at the 92nd percentile among all GPUs — a clear mismatch in raw capability that shows up in the measured frame rates.

Looking at the combo's position more critically, the RTX 5090 D's nearest rivals in average benchmark score include the AMD Radeon RX 6850M XT at 1.6% higher score and the NVIDIA Tesla P100 PCIe 16 GB at 2.4% higher. The i5-9400's nearest rivals are clustered tightly: the Intel Core i7-1068NG7 is just 0.2% ahead, while the AMD Ryzen 5 PRO 1500 is 0.4% behind. This tells us the CPU is performing exactly as expected for its class — no surprises, but also no headroom for the GPU to stretch its legs.

The rank of 284 might seem modest for a combo containing one of the most powerful consumer GPUs ever made, but the data shows why. Fivem is a multiplayer title that depends heavily on single-thread performance and consistent frame delivery. The i5-9400's six cores and six threads, boosting to 4.10 GHz, provide adequate but not exceptional throughput. The result is a system that outperforms 90.5% of tested combos, yet leaves significant performance on the table compared to what the RTX 5090 D could deliver with a stronger processor.

# FAQ

Q: Is the Intel Core i5-9400 bottlenecking the RTX 5090 D in Fivem?

A: Yes, the data strongly suggests CPU limitation. At 1080p Low, the combo achieves 213 FPS, while at 1080p Ultra it drops to 165 FPS — a relatively small 22.5% penalty for maxing out graphics settings. This indicates the CPU is the limiting factor at lower settings, as the GPU has ample headroom that the processor cannot feed.

Q: How does the i5-9400 compare to its nearest CPU rivals?

A: The i5-9400's average benchmark score is 2254, placing it within 0.4% of all four nearest rivals. The Intel Core i7-1068NG7 scores 2259 (0.2% higher), the Intel Core i3-10305 scores 2264 (0.4% higher), while the Intel Core i7-10710U at 2248 and AMD Ryzen 5 PRO 1500 at 2246 are marginally behind. This is a tightly clustered field with no meaningful performance separations.

Q: What is the best resolution for this combo in Fivem?

A: At 1440p High, the combo delivers 157 FPS, which represents the sweet spot between visual fidelity and frame rate headroom. At 4K High, it drops to 93 FPS, which is still playable but shows the GPU beginning to work harder. At 1080p, frame rates exceed 165 FPS at all settings, but the CPU limits scalability beyond that point.

Q: How does the RTX 5090 D compare to its nearest GPU rivals in average benchmarks?

A: The RTX 5090 D has an average benchmark score of 77712. The AMD Radeon RX 6650M XT scores 76904 (1.1% lower), while the AMD Radeon RX 6850M XT scores 78940 (1.6% higher). The NVIDIA Tesla P100 variants score 79396 and 79605, which are 2.1% and 2.4% higher respectively. The GPU is competitive with its immediate peers.

Q: Does the i5-9400's lack of hyper-threading hurt in Fivem?

A: The i5-9400 has 6 cores and 6 threads, with no hyper-threading. Its Cinebench R23 multicore score of 6629 and single-core score of 935 indicate solid per-core performance. In Fivem's multiplayer environment, the 4.10 GHz boost clock helps, but the thread count limits how much the CPU can handle when many players and vehicles are active simultaneously.

Q: What does the 92nd percentile GPU ranking mean for longevity?

A: The RTX 5090 D outperforms 92% of all GPUs in the database, making it an exceptionally powerful part that will remain relevant for years. However, the i5-9400 at the 47th percentile will likely become the more significant upgrade path sooner, as Fivem and other multiplayer titles continue to demand more CPU throughput.

# Resolution Scaling

The measured FPS data reveals a clear scaling pattern from 1080p to 4K that highlights the changing bottleneck between CPU and GPU. At 1080p High, the combo produces 181 FPS. Moving to 1440p High, it delivers 157 FPS — a 13.3% drop. At 4K High, it falls to 93 FPS, representing a 48.6% reduction from 1080p High. This scaling curve is characteristic of a system where the GPU becomes increasingly dominant as resolution rises.

At Low settings, the pattern shifts. The 1080p Low result of 213 FPS drops to 186 FPS at 1440p Low (12.7% decrease) and further to 147 FPS at 4K Low (31.0% decrease from 1080p). The smaller percentage drop at higher resolutions when using Low settings indicates that the CPU is the primary constraint at 1080p — the GPU is not being fully utilized. At 4K Low, the GPU still has headroom, but the frame rate ceiling imposed by the CPU becomes less relevant as the GPU starts to work harder.

The Medium settings row provides the most complete data, including min and max FPS values. At 4K Medium, the combo averages 116 FPS with a minimum of 99 FPS and maximum of 133 FPS. At 1440p Medium, it averages 170 FPS with min/max of 145/196. At 1080p Medium, the average is 196 FPS with min/max of 166/225. The gap between 1080p and 1440p Medium is 13.3%, while the gap between 1440p and 4K Medium is 31.8%. This widening gap confirms that the GPU's workload increases disproportionately at higher resolutions.

The limiting component analysis is straightforward: below 1440p, the i5-9400's six cores are the ceiling. Above 1440p, the RTX 5090 D's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth begin to matter more. The 4K Ultra result of 72 FPS, versus 93 FPS at 4K High, shows a 22.6% performance cost for the Ultra preset, indicating the GPU is being pushed hard at this setting while the CPU remains relatively constant in its contribution.

# Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 213 FPS average, Medium settings yield 196 FPS with a 166-225 FPS range, High settings reach 181 FPS, and Ultra settings drop to 165 FPS. The spread from Low to Ultra is 48 FPS, or 22.5%. This is a relatively narrow range, which strongly suggests the CPU is capping performance — if the GPU were the limit, the gap between Low and Ultra would be much wider given the RTX 5090 D's capabilities.

At 2560x1440, the performance hierarchy remains consistent. Low settings hit 186 FPS, Medium averages 170 FPS with a 145-196 FPS range, High achieves 157 FPS, and Ultra manages 130 FPS. The Low-to-Ultra spread is 56 FPS, or 30.1%. The increased spread at 1440p compared to 1080p indicates the GPU is becoming a larger factor, but the CPU still imposes a ceiling — note that 1440p Low at 186 FPS is still below 1080p Ultra at 165 FPS, showing the resolution penalty is manageable at lower settings.

At 3840x2160, the picture changes dramatically. Low settings produce 147 FPS, Medium averages 116 FPS with a 99-133 FPS range, High drops to 93 FPS, and Ultra falls to 72 FPS. The Low-to-Ultra spread is 75 FPS, or 51.0%. This is the clearest evidence that the GPU is now the dominant factor. The 4K Ultra result of 72 FPS is less than half of the 1080p Low result of 213 FPS, a 66.2% reduction that reflects the massive pixel throughput demands at 4K.

The Medium settings at each resolution offer the most complete picture because they include min and max FPS. At 1080p Medium, the 166 FPS minimum still exceeds the 4K Ultra average of 72 FPS by a factor of 2.3. The consistency of frame delivery, measured by the min-to-max range, is tightest at 1080p Medium (59 FPS range) and widest at 4K Medium (34 FPS range), indicating more frame-time variance at higher resolutions as the GPU works harder.

# CPU Role

The Intel Core i5-9400 is a six-core, six-thread processor based on the Coffee Lake architecture, built on Intel's 14 nm process. It operates at a 2.90 GHz base clock and boosts to 4.10 GHz. The 9 MB shared L3 cache and dual-channel DDR4 memory support with 42.7 GB/s bandwidth provide adequate data throughput for most gaming scenarios, but the lack of hyper-threading means only six threads are available for all workloads.

In CPU benchmark terms, the i5-9400 scores 6629 in Cinebench R23 multicore and 935 in single-core. Its Geekbench scores are 5141 multicore and 1389 single-core. These figures place it at the 47th percentile of all CPUs, which is below average for a gaming-focused processor in 2025. The nearest rivals, all within 0.4% of its average score of 2254, include mobile and desktop parts that demonstrate the i5-9400 performs at the level of a mid-range processor from its generation.

Fivem's multiplayer nature means the CPU must handle many concurrent entities — players, vehicles, and world state updates. The i5-9400's six threads can manage this, but the 4.10 GHz boost clock is the key asset. The measured FPS data shows that at 1080p Low, the combo hits 213 FPS, which is likely near the CPU's practical ceiling for this game. The fact that 1080p Ultra only drops to 165 FPS — a 22.5% reduction — while the GPU workload increases substantially, confirms that the processor is the limiting factor at lower resolutions.

The CPU's PCIe Gen 3 interface with 16 lanes is another consideration. The RTX 5090 D supports PCIe 5.0 x16, but the i5-9400's Gen 3 connection could theoretically reduce data transfer rates. However, the measured FPS in Fivem does not show a dramatic penalty from this interface mismatch, suggesting the game's data demands do not saturate the available bandwidth.

# Settings Recommendations

The measured data points to Medium settings as the optimal choice for this combo across all resolutions. At 1080p Medium, the combo delivers 196 FPS average with a minimum of 166 FPS — both figures are well above the 144Hz refresh rate common on modern monitors. At 1440p Medium, the average of 170 FPS with a 145 FPS minimum still provides smooth gameplay, and at 4K Medium, the 116 FPS average with a 99 FPS minimum is playable for competitive multiplayer.

High settings offer diminishing returns relative to Medium. At 1080p High, the average drops to 181 FPS (7.7% lower than Medium), at 1440p High it falls to 157 FPS (7.6% lower), and at 4K High it drops to 93 FPS (19.8% lower). The visual improvement from Medium to High is unlikely to justify these frame rate losses, particularly at 4K where the drop below 100 FPS becomes noticeable.

Ultra settings are the least recommended. At 1080p Ultra, the 165 FPS average is still playable, but the 22.5% penalty versus Low settings shows the CPU is already constraining performance. At 1440p Ultra, 130 FPS is acceptable, but at 4K Ultra, the 72 FPS average falls below the threshold for smooth competitive play. The RTX 5090 D's 32 GB of GDDR7 memory and 104.8 TFLOPS of FP32 compute can handle Ultra settings, but the i5-9400 cannot feed the GPU fast enough at lower resolutions, and at 4K Ultra the GPU itself becomes taxed.

For the best balance of visual quality and frame rate, Medium at 1440p is the standout choice. The 170 FPS average with a 145 FPS minimum provides a smooth experience with good image quality. At 4K, Medium at 116 FPS is the highest setting that maintains triple-digit frame rates. Players with 144Hz displays should strongly prefer Medium over High, as the latter drops to 93 FPS at 4K — below the refresh threshold.
