Fivem

Fivem, Rockstar’s multiplayer modification platform, presents a unique scaling pattern for the AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 4080 combo. The measured data shows a clear transition from a GPU-bound scenario at 4K to a more balanced workload at 1080p, where the CPU’s capabilities become increasingly relevant. This analysis breaks down the measured FPS across resolutions, settings, and component roles.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, indicating that the RTX 4080 is the primary limiting factor at higher resolutions. At Low settings, the average FPS falls from 239 at 1080p to 157 at 1440p, a 34% reduction, and then to 87 at 4K, a further 45% reduction from the 1440p figure. This scaling is typical for a game where pixel throughput dominates at lower preset levels.

At High settings, the progression is 151 FPS at 1080p, 99 FPS at 1440p, and 55 FPS at 4K. The percentage drops are 34% and 44%, respectively, mirroring the Low preset's behavior. This consistency suggests that the rendering load scales nearly linearly with pixel count, which is a hallmark of a GPU-bound workload. The RTX 4080's 16 GB of VRAM and 716.8 GB/s bandwidth are sufficient to feed the pipeline, but raw compute power at these resolutions is the deciding factor.

The Medium preset tells a similar story, with averages of 189 FPS at 1080p, 124 FPS at 1440p, and 69 FPS at 4K. The drop from 1080p to 1440p is 34%, and from 1440p to 4K is 44%. The Ultra preset is the most demanding, yielding 117 FPS at 1080p, 77 FPS at 1440p, and 43 FPS at 4K. Here, the drops are 34% and 44% as well, showing that even at the highest graphical fidelity, the scaling pattern remains unchanged.

This data suggests that at 4K, the combo is heavily GPU-bound across all settings. The gap between Low and Ultra at 4K is 44 FPS (87 vs. 43), which is significant, but the relative scaling between resolutions is uniform. At 1080p, the picture changes. The spread between Low and Ultra is 122 FPS (239 vs. 117), which is much larger in absolute terms. This wider gap at 1080p indicates that the CPU, the Ryzen 9 8945HX, has more headroom to push frames when the GPU is less stressed, but it still manages to keep up with the GPU’s output without becoming a hard bottleneck.

The key takeaway is that 1440p is the sweet spot for this combo. The FPS at High (99) and Medium (124) presets are playable, while 4K demands compromises. At 1080p, the system is capable of very high frame rates, but the scaling shows that the GPU is no longer the sole constraint; the CPU's 16 cores and 32 threads begin to matter more for maintaining those high numbers.

Settings Recommendations

For 4K gaming, the data shows that the Low preset, with an average of 87 FPS, is the only option that consistently clears the 60 FPS threshold. The Medium preset delivers 69 FPS, which is playable but with occasional dips to 59 FPS, as indicated by the min FPS data. High (55 FPS) and Ultra (43 FPS) are not recommended for a smooth experience at this resolution, as they fall below the 60 FPS target.

At 1440p, the High preset is the best balance. The average of 99 FPS is smooth, and the visual uplift from Medium is worthwhile. The Medium preset’s 124 FPS is faster but sacrifices detail. Ultra at 77 FPS is also viable, but High offers a better margin for demanding scenes. The Low preset at 157 FPS is for competitive play, but it leaves performance on the table.

For 1080p, the Medium preset is the recommended choice. The average of 189 FPS is excellent, and the min FPS of 160 ensures that even in busy multiplayer lobbies, the frame rate stays high. The High preset at 151 FPS is also strong, but Medium provides a better buffer. The Low preset at 239 FPS is for high-refresh-rate monitors, but it shows that the CPU is capable of feeding the GPU well beyond typical needs. Ultra at 117 FPS is respectable, but the jump from Medium is not worth the performance cost.

The measured rows indicate that the Medium preset offers the most consistent experience across all resolutions. It provides a significant boost over Low in visual quality while maintaining a playable frame rate at 4K and a very high frame rate at 1080p. For users with a 144Hz or 165Hz monitor at 1440p, High is the best choice to balance image quality and refresh rate. The data strongly suggests avoiding Ultra at 4K unless a lower frame rate is acceptable.

How This Combo Ranks

The combo of the AMD Ryzen 9 8945HX and the NVIDIA GeForce RTX 4080 ranks 941st out of 3005 tested combos in Fivem. This places it in the 69th percentile of all configurations, meaning it outperforms more than two-thirds of the systems tested. This is a solid result, but it is not top-tier, which reflects the game’s heavy dependence on both single-threaded CPU performance and raw GPU throughput.

The CPU’s nearest rivals help contextualize its contribution. The Ryzen 9 8945HX has an average benchmark score of 76212, which is 0.1% ahead of the Intel Core Ultra 9 285HX (76155) and 0.6% ahead of the AMD Ryzen 9 9950X3D (75779). It trails the AMD EPYC Embedded 8224P (76492) and the AMD Ryzen Threadripper PRO 9945WX (76513) by 0.4%. These are all very close scores, indicating that the 8945HX is performing at the expected level for a high-end mobile CPU.

On the GPU side, the RTX 4080’s average benchmark score is 54247. Its nearest rival, the RTX 4080 SUPER, scores 54209, which is a 0.1% difference. The AMD Radeon Pro W5700X (54828) and the AMD Radeon RX 6750 GRE 12 GB (55698) are 1.1% and 2.6% ahead, respectively. The AMD Radeon 8060S (55757) is 2.7% ahead. These small deltas show that the RTX 4080 is performing within its expected band, and the ranking is not being dragged down by a defective or throttling component.

The rank of 941 out of 3005 suggests that while the individual components are strong, the combo is not optimized for Fivem’s specific engine. The game’s multiplayer nature introduces CPU overhead that can limit performance, and the data shows that other combos with even faster single-threaded CPUs or different GPU configurations achieve higher frame rates. The 8945HX’s boost clock of 5.40 GHz is high, but its performance in Fivem is likely tempered by the game’s reliance on fewer cores.

Measured FPS Breakdown

At 1080p, the measured FPS shows a clear hierarchy across presets. Low settings produce an average of 239 FPS, with no min or max data recorded. Medium settings deliver 189 FPS, with a min of 160 and a max of 217. High settings average 151 FPS. Ultra settings drop to 117 FPS. The gap between Low and Ultra is 122 FPS, which is substantial.

Moving to 1440p, the averages are lower but still playable. Low settings yield 157 FPS. Medium settings produce 124 FPS, with a min of 106 and a max of 143. High settings average 99 FPS. Ultra settings average 77 FPS. The gap between Low and Ultra is 80 FPS, which is smaller than at 1080p, showing the GPU’s increasing workload.

At 4K, the performance drops significantly. Low settings average 87 FPS. Medium settings average 69 FPS, with a min of 59 and a max of 79. High settings average 55 FPS. Ultra settings average 43 FPS. The gap between Low and Ultra is 44 FPS, which is the smallest of the three resolutions. This indicates that at 4K, the GPU is the primary bottleneck, and the CPU’s speed has less impact on the final frame rate.

The min and max FPS data for Medium settings provides insight into frame pacing. At 1080p, the range is 160-217 FPS, which is a 57 FPS variance. At 1440p, the range is 106-143 FPS, a 37 FPS variance. At 4K, the range is 59-79 FPS, a 20 FPS variance. This tightening of the range at higher resolutions suggests that the GPU’s consistent frame times are more predictable when it is fully saturated, whereas at lower resolutions, CPU-related hitches can cause larger fluctuations.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component at 4K, as evidenced by the sharp FPS drop as resolution increases. With 16 GB of GDDR6X memory on a 256-bit bus, the card has ample bandwidth (716.8 GB/s) for Fivem’s textures and geometry. The memory clock is listed at 1400 MHz, with an effective data rate of 22.4 Gbps. This memory configuration is sufficient for the game, and the data shows no signs of VRAM capacity limitations at any setting.

The GPU’s base clock is 2205 MHz, with a boost clock of 2505 MHz. These clocks are relevant for sustained performance. The measured FPS at 4K High (55 FPS) and 4K Ultra (43 FPS) suggest that the GPU is running near its limits. The card’s 9728 shading units and 112 ROPs are being fully utilized at these settings. The FP32 performance of 48.74 TFLOPS is high, but Fivem’s engine appears to be more sensitive to memory bandwidth and pixel fill rate than raw compute.

The RTX 4080’s role is clear: it is the gatekeeper for high-resolution gameplay. At 1080p, the GPU can render frames quickly enough to reach 239 FPS on Low, but the CPU is likely limiting the absolute maximum. At 4K, the GPU is the limiting factor, and the data shows that even the Low preset only achieves 87 FPS. The card’s 76 RT cores and 304 tensor cores are not heavily utilized in Fivem, as the game does not feature extensive ray tracing or DLSS support in the measured scenarios. The GPU’s average benchmark score of 54247 and its 86th percentile ranking among all GPUs confirm that it is a high-end part, but its performance in this game is dictated by resolution and preset demands.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture. Its base clock is 2.50 GHz, and it boosts up to 5.40 GHz. This high boost clock is crucial for Fivem, which often relies on a few fast cores for game logic and physics. The CPU’s 64 MB of L3 cache is also beneficial for reducing memory latency in multiplayer scenarios.

The CPU’s role becomes more apparent at 1080p. The jump from 151 FPS at High to 239 FPS at Low shows that the CPU can feed the GPU with enough data to push frame rates very high when the GPU is not the bottleneck. The 8945HX’s performance in Cinebench R23 (42713 multi-core, 6030 single-core) indicates strong single-threaded capability, which is directly relevant to Fivem’s performance. However, the combo’s rank of 941 suggests that other CPUs with even higher single-core scores may achieve better results.

At 4K, the CPU’s impact is less visible. The FPS at Low (87) and High (55) are primarily determined by the GPU. The CPU is still important for maintaining minimum frame rates, but the average FPS is not significantly affected by the processor’s speed. The data shows that the 8945HX has enough headroom to avoid being a hard bottleneck at 4K, as the GPU is clearly the limiting factor. The CPU’s 5.40 GHz boost clock is likely being reached in these scenarios, but the game’s engine cannot utilize all 16 cores effectively, so the extra threads are underutilized.

The CPU’s benchmark scores against rivals, such as being 0.1% ahead of the Intel Core Ultra 9 285HX and 0.6% ahead of the AMD Ryzen 9 9950X3D, show that it is a top-tier mobile processor. In Fivem, its performance is adequate for high-refresh-rate gaming at 1080p and 1440p, but the combo’s overall rank indicates that the platform is not the absolute best for this specific game. The CPU’s 95th percentile ranking among all CPUs is impressive, but the game’s engine rewards higher single-threaded performance, which is where the 8945HX excels but is not unmatched.
