# Fortnite Performance Analysis: AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 4060

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 4060 delivers a firmly playable Fortnite experience across most settings, but the data reveals a system that is heavily GPU-limited at higher resolutions. At 1080p Low, the combo achieves 218 FPS average, which is competitive for high-refresh-rate monitors. However, the frame rate collapses to 26 FPS at 4K Ultra, exposing the RTX 4060's 8 GB VRAM and 128-bit memory bus as the primary bottleneck. The CPU, a 16-core Zen 4 Dragon Range part with a 5.40 GHz boost clock, is never the limiting factor in this pairing. The combo ranks 1632nd out of 2740 tested combinations, placing it in the lower-middle tier of the database, though this rank is influenced heavily by the GPU's modest standing among all tested graphics cards.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread mobile processor built on TSMC's 5 nm process, using the Zen 4 architecture with the Dragon Range codename. Its base clock is 2.50 GHz, boosting up to 5.40 GHz, and it carries 64 MB of L3 cache alongside 1 MB of L2 per core. These specifications translate into a processor that scores 42713 points in Cinebench R23 multi-core and 6030 points in single-core, placing it in the 95th percentile among all CPUs in the database. Its nearest rivals include the Intel Core Ultra 9 285HX (0.1% faster) and the AMD Ryzen 9 9950X3D (0.6% faster), indicating that this chip sits at the very top of mobile CPU performance.

In Fortnite, the CPU's role is to feed the GPU with draw calls and handle game logic, physics, and building mechanics. The measured data shows that at 1080p Low, the system produces 218 FPS, which is an excellent result that suggests the CPU is capable of driving very high frame rates. The single-thread score of 6030 in Cinebench R23 is particularly relevant here, as Fortnite's engine benefits from strong per-core performance. The 5.40 GHz boost clock and Zen 4's high IPC ensure that even the most demanding scenes with many players and structures will not cause CPU-bound stutters.

The multi-threaded performance is also substantial, with a PassMark multithread score of 51405 and an integer math score of 195180. While Fortnite does not typically scale perfectly across 16 cores, the headroom provided by this processor means that background tasks, streaming, or recording software will not compete with the game for resources. The data compression score of 677755 in PassMark further indicates that this CPU handles data-heavy workloads with ease, which is useful for games that stream assets from storage.

The CPU's position in the 95th percentile of all CPUs, combined with its average benchmark score of 76212, confirms that it is not a limiting factor in this combination. When comparing to the nearest rivals, the Ryzen 9 8945HX is statistically tied with the Intel Core Ultra 9 285HX (deltaPct: 0.1) and the AMD EPYC Embedded 8224P (deltaPct: -0.4). This means that swapping the CPU for any of these alternatives would yield virtually identical Fortnite performance, reinforcing the conclusion that the GPU is the dominant constraint.

GPU Role

The NVIDIA GeForce RTX 4060 is built on the Ada Lovelace architecture using the AD107 chip, fabricated on a 5 nm process with 18,900 million transistors. It features 3072 shading units, 96 TMUs, 48 ROPs, 24 RT cores, and 96 tensor cores. The GPU operates at a base clock of 1830 MHz and boosts to 2460 MHz, with memory running at 2125 MHz (17 Gbps effective) across an 8 GB GDDR6 frame buffer on a 128-bit bus, yielding 272.0 GB/s of bandwidth. The FP32 performance is 15.11 TFLOPS, and the card carries a TDP of 115 W.

In the context of Fortnite, the RTX 4060's specifications directly explain the measured frame rates. At 1080p Low, the card produces 218 FPS, which is a strong result for competitive play. The 8 GB VRAM is sufficient for 1080p and 1440p at most settings, as Fortnite is not a particularly VRAM-hungry title. However, the 128-bit memory bus and 272.0 GB/s bandwidth become a bottleneck at higher resolutions and settings. At 4K Ultra, the average FPS drops to 26, and at 4K High it is only 40 FPS. These figures indicate that the GPU is overwhelmed by the pixel count and texture complexity.

The GPU's benchmark scores further contextualize its position. It scores 19545 in PassMark G3D, placing it in the 61st percentile among all GPUs, with an average benchmark score of 17639. Its nearest rivals are surprising: the AMD Radeon HD 7790 (0.2% faster), the AMD Radeon 780M (0.3% slower), and the AMD Radeon Pro 560 (0.5% slower). This places the RTX 4060 in a peculiar position where it is comparable to older discrete GPUs and modern integrated graphics, which reflects the impact of its limited memory bus and VRAM capacity in synthetic benchmarks that do not always reflect gaming performance.

In Fortnite specifically, the RTX 4060's ray tracing capabilities, supported by 24 RT cores, are irrelevant at the measured settings since the data does not include any ray tracing presets. The 96 tensor cores enable DLSS, which could theoretically improve frame rates, but the measured FPS values are raw rasterization results. The card's DirectX 12 Ultimate support (12_2) and Vulkan 1.4 API compatibility ensure it is fully compliant with Fortnite's modern rendering requirements.

Settings Recommendations

The measured data provides four settings presets (Low, Medium, High, Ultra) across three resolutions. At 1080p, the differences are stark. Low produces 218 FPS, Medium drops to 154 FPS, High to 119 FPS, and Ultra to 79 FPS. The step from Low to Medium costs 64 FPS (29%), while the step from High to Ultra costs 40 FPS (34%). For competitive players seeking maximum frame rates, 1080p Low is the clear choice, delivering 218 FPS with no measured minimum below 131 FPS at Medium. The Medium preset at 1080p offers 154 FPS with a minimum of 131 FPS, which is still well above the 144 Hz threshold for most gaming monitors.

At 1440p, the data shows 139 FPS on Low, 98 FPS on Medium (minimum 83 FPS), 76 FPS on High, and 50 FPS on Ultra. The Medium preset at 1440p is the sweet spot for a balance between visual quality and smoothness, as the 83 FPS minimum is acceptable for most players. High at 1440p drops to 76 FPS, which is borderline for fast-paced action. At 4K, the results are less encouraging: Low produces 73 FPS, Medium 52 FPS (minimum 44 FPS), High 40 FPS, and Ultra 26 FPS. Only 4K Low is consistently playable, and even that is marginal.

The data suggests that the optimal experience is 1080p Medium, which delivers 154 FPS average with a minimum of 131 FPS. This provides a 31% improvement over High at the same resolution while sacrificing some visual fidelity. For players who prioritize image quality over raw speed, 1440p Medium at 98 FPS is a reasonable compromise. The Ultra preset should be avoided at all resolutions, as the frame rate drops below 80 FPS even at 1080p, and the visual difference between High and Ultra in Fortnite is often subtle. The 4K resolution is only viable at Low settings, and even then, the 73 FPS average is below what most competitive players would consider acceptable.

How This Combo Ranks

The AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 4060 combination ranks 1632nd out of 2740 tested combos in Fortnite, placing it in the 59.6th percentile of all tested systems. This rank is notably lower than the individual component percentiles (CPU at 95th, GPU at 61st), which indicates that the GPU is dragging the overall performance down relative to other combinations in the database. The rank of 1632 suggests that there are 1108 tested combos that perform worse, and 1631 that perform better.

This ranking is heavily influenced by the GPU's position. The RTX 4060's 61st percentile among all GPUs means that a significant portion of tested graphics cards are faster, and when paired with a top-tier CPU like the Ryzen 9 8945HX, the GPU becomes the sole limiting factor. The data supports this: at 1080p Low, the system achieves 218 FPS, which is excellent, but at 4K Ultra it drops to 26 FPS. A more balanced pairing, such as a mid-range CPU with a higher-tier GPU, would likely rank higher in the database because the GPU would not be the bottleneck.

The CPU's nearest rivals include the Intel Core Ultra 9 285HX, which has a deltaPct of 0.1, meaning it is essentially identical in performance. The AMD EPYC Embedded 8224P and AMD Ryzen Threadripper PRO 9945WX are both 0.4% slower, while the AMD Ryzen 9 9950X3D is 0.6% faster. These differences are negligible in gaming, so swapping the CPU for any of these would not change the combo's rank meaningfully. The GPU's nearest rivals, including the AMD Radeon HD 7790 and AMD Radeon 780M, are all within 0.7% of the RTX 4060's average score, further confirming that the GPU is the performance ceiling.

Resolution Scaling

The measured FPS data shows a clear and dramatic drop as resolution increases from 1080p to 4K. At Low settings, the average FPS goes from 218 at 1080p to 139 at 1440p (a 36% drop) and then to 73 at 4K (a 48% drop from 1440p). At Medium settings, the progression is 154 FPS at 1080p, 98 FPS at 1440p (36% drop), and 52 FPS at 4K (47% drop). High settings show 119 FPS at 1080p, 76 FPS at 1440p (36% drop), and 40 FPS at 4K (47% drop). Ultra settings follow the same pattern: 79 FPS at 1080p, 50 FPS at 1440p (37% drop), and 26 FPS at 4K (48% drop).

This consistent 36-37% drop from 1080p to 1440p and 47-48% drop from 1440p to 4K across all settings is a classic signature of GPU-bound performance. If the CPU were the limiting factor, the frame rate would remain relatively constant across resolutions, as the CPU workload does not scale with pixel count. The fact that the drops are nearly identical across all four settings presets further confirms that the GPU is the bottleneck, regardless of whether the game is running at Low or Ultra.

The scaling pattern also reveals that the RTX 4060's memory bandwidth (272.0 GB/s) and 8 GB VRAM are insufficient for 4K gaming. At 4K, the frame rate at Ultra (26 FPS) is less than one-third of the 1080p Low result (218 FPS). This is a larger drop than would be expected from pure pixel count scaling (which would be roughly 4x fewer pixels at 1080p compared to 4K, suggesting a theoretical 4x FPS increase, but the actual drop is much larger). The extra penalty comes from the GPU running out of memory bandwidth and possibly VRAM capacity, forcing the card to work inefficiently.

The CPU's performance at 1080p Low (218 FPS) indicates that it is capable of driving frame rates well above what the GPU can sustain at higher resolutions. The 16-core processor with a 5.40 GHz boost clock is not the limiting factor even at the lowest settings, where CPU-bound scenarios would typically manifest. This is a strong confirmation that any frame rate improvements in this combo would require a GPU upgrade, not a CPU upgrade.
