Fivem

The Intel Core i5-9400 paired with the NVIDIA GeForce GTX 1660 Ti produces a clear performance hierarchy in Fivem, with the data showing a steep penalty as resolution climbs. At 1920x1080 with Low settings, the combo delivers 125.1 FPS, which drops to 84.1 FPS at 2560x1440 and further to 42.4 FPS at 3840x2160. This represents a 32.8% reduction from 1080p to 1440p, and a 66.1% reduction from 1080p to 4K. The scaling pattern suggests that at lower resolutions, the system has headroom, but the 4K results indicate a hard ceiling. The gap between Low and Ultra at 1080p is 63.6 FPS (125.1 vs. 61.5), which is a substantial spread that highlights how settings choices can dramatically alter the experience. At 4K, the same Low-to-Ultra gap narrows to 22.1 FPS (42.4 vs. 20.3), implying that resolution scaling flattens the impact of settings because the GPU becomes the primary bottleneck. The 1440p data shows a middle ground: Low produces 84.1 FPS, Medium 61.9 FPS, and High 52.3 FPS, with Ultra at 38.8 FPS. The measured rows indicate that 4K Ultra at 20.3 FPS is essentially unplayable for smooth motion, while 4K Low at 42.4 FPS is borderline. The limiting component at 4K is the GPU, as the frame rate collapse from 1080p to 4K is far steeper than what a CPU-bound scenario would produce.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor with a base clock of 2.90 GHz and a boost clock of 4.10 GHz, based on the Coffee Lake architecture on a 14 nm process. Its synthetic benchmark scores place it at the 50th percentile among all CPUs, with an average benchmark score of 2305. In Cinebench R23, it scores 7969 multi-core and 1125 single-core. The nearest rivals in the CPU benchmark database are the Intel Core i3-10305 and Intel Core i3-1125G4, both with an average score of approximately 2300 and a deltaPct of 0.2% relative to the i5-9400. The Intel Xeon E-2134 is also close at 2295 with a 0.4% delta, while the Intel Core i7-8809G sits slightly ahead at 2319 with a -0.6% delta. These tight deltas indicate that the i5-9400 sits in a crowded mid-range segment where performance differences are minimal. In Fivem, the CPU’s role is most evident in the 1080p Low setting, where the frame rate reaches 125.1 FPS. This high value suggests that the 6 cores and 6 threads are sufficient to feed the GPU at lower resolutions, but the lack of hyper-threading may become a factor in multiplayer scenarios with many entities. The boost clock of 4.10 GHz helps with single-threaded tasks, which is typical for game logic, and the 9 MB of shared L3 cache provides adequate data locality. The 65W TDP and dual-channel DDR4 memory support with 42.7 GB/s bandwidth are standard for this class. The data shows that at 4K, the CPU is not the limiting factor, as the frame rates drop uniformly across settings, pointing to GPU saturation. However, at 1080p, the CPU’s ability to maintain 125.1 FPS on Low indicates it can handle high refresh rates in less demanding scenes. The Cinebench R20 scores of 3346 multi-core and 472 single-core reinforce the picture of a capable mid-range chip that pairs well with a mid-range GPU.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is built on the Turing architecture with a 12 nm process, featuring 1536 shading units, 96 texture mapping units, and 48 ROPs. It has 6 GB of GDDR6 memory on a 192-bit bus, delivering 288.0 GB/s of bandwidth. The GPU’s base clock is 1500 MHz with a boost clock of 1770 MHz, and its memory runs at 1500 MHz (12 Gbps effective). The pixel rate is 84.96 GPixel/s, and the texture rate is 169.9 GTexel/s, with FP32 performance at 5.437 TFLOPS. The GPU’s benchmark percentile is 55 among all GPUs, with an average benchmark score of 13925. Its nearest rivals include the AMD Radeon RX 570X with a score of 13871 and a deltaPct of 0.4%, the NVIDIA Tesla K10 at 14029 with a -0.7% delta, the NVIDIA RTX A2000 Mobile at 13821 with a 0.8% delta, and the NVIDIA GeForce GTX 680 at 13812 with a 0.8% delta. These deltas show the GTX 1660 Ti is essentially equal to these cards in aggregate benchmark scores, but in Fivem, the measured FPS reveals its practical limits. At 4K, the GPU struggles: High settings yield 30.5 FPS, Medium 35.6 FPS, Low 42.4 FPS, and Ultra 20.3 FPS. The 6 GB VRAM capacity is sufficient for 1080p and 1440p, but at 4K, the memory bandwidth of 288.0 GB/s becomes a constraint, as the frame rates drop below the 60 FPS threshold even on Low. The 192-bit bus width and GDDR6 memory are typical for this tier, but the data indicates that the GPU is the primary bottleneck at 4K, given that the frame rate differences between settings are relatively small (22.1 FPS between Low and Ultra) compared to the resolution scaling. At 1440p, the GPU delivers 84.1 FPS on Low, which is respectable, but Ultra drops to 38.8 FPS, showing that the card lacks the headroom for high settings at this resolution. At 1080p, the GPU performs well, with 125.1 FPS on Low and 75.9 FPS on High, indicating that it can handle competitive play at lower settings. The 120W TDP and dual-slot design make it a manageable card, and its DirectX 12 (12_1) support aligns with modern game requirements.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and desired frame rate. At 1920x1080, the Medium preset offers 95.8 FPS, which is a strong balance between visual quality and smoothness, especially for a multiplayer game like Fivem where responsiveness matters. High settings produce 75.9 FPS, which is still playable, but the drop from Medium to High is 19.9 FPS, suggesting that the visual gains at High come at a noticeable cost. Ultra at 61.5 FPS is the minimum for acceptable smoothness, but it leaves little headroom for frame drops in busy scenes. For players prioritizing frame rate, Low at 125.1 FPS provides the best competitive advantage, though it sacrifices visual fidelity. At 2560x1440, the Medium preset delivers 61.9 FPS, which is just above the 60 FPS threshold and is the recommended choice for a balanced experience. High at 52.3 FPS is playable but may feel less smooth, while Low at 84.1 FPS is ideal for those who want high refresh rates at this resolution. Ultra at 38.8 FPS is not recommended, as it falls below the smoothness threshold and the visual improvement over High or Medium is not worth the frame rate penalty. At 3840x2160, all settings struggle: Low at 42.4 FPS is the only viable option for playability, while Medium at 35.6 FPS and High at 30.5 FPS are marginal. Ultra at 20.3 FPS is effectively unplayable for most users. The data indicates that for this combo, 1080p Medium is the best overall experience, as it provides a high frame rate (95.8 FPS) with reasonable visual settings. If the user has a 1440p monitor, Medium is the sweet spot, but they must accept a lower frame rate (61.9 FPS) than at 1080p. The measured rows show a consistent pattern: lowering settings from Ultra to Low yields a 63.6 FPS gain at 1080p, a 45.3 FPS gain at 1440p, and a 22.1 FPS gain at 4K. This diminishing return means that at higher resolutions, the settings have less impact because the GPU is already saturated.

How This Combo Ranks

In the database of tested combos for Fivem, this specific pairing of the Intel Core i5-9400 and NVIDIA GeForce GTX 1660 Ti ranks 1585 out of 1792 total combinations. This places it in the lower half of all tested systems, with a rank percentile that indicates it is outperformed by roughly 88% of the combos in the database. The rank is a reflection of the overall performance across all measured resolutions and settings, and the data shows that this combo is not competitive with higher-end systems. The CPU’s 50th percentile ranking and the GPU’s 55th percentile ranking both indicate mid-range components, but their combined score in Fivem is dragged down by the 4K results, where the system falls below 45 FPS on all settings. At 1080p, the combo performs adequately, with Low settings reaching 125.1 FPS, which would rank higher in a resolution-specific comparison. However, the overall rank of 1585 out of 1792 suggests that most other tested combos achieve better frame rates across the board. The nearest rivals in the GPU benchmark (RX 570X, Tesla K10, RTX A2000 Mobile, GTX 680) all have similar aggregate scores, but in Fivem, the GTX 1660 Ti’s 6 GB VRAM and 288.0 GB/s bandwidth may not be enough to push the rank higher. The CPU’s nearest rivals (i3-10305, i3-1125G4, Xeon E-2134, i7-8809G) are also clustered within 0.6% of its average score, so the CPU is not a differentiator. The combo rank of 1585 out of 1792 indicates that this system is suited for 1080p gaming at medium to high settings, but it falls short at higher resolutions. For users with this hardware, the data suggests that 1080p Medium is the best way to maximize the experience, as the system’s rank improves when not burdened by 4K rendering. The measured FPS at 1080p Medium (95.8 FPS) is above the 60 FPS target, which is a positive sign, but the overall rank reflects that many other combinations offer superior performance in this game.
