Fortnite

The data below covers Fortnite performance for the AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 4080, using the measured FPS values recorded for four quality presets (Low, Medium, High, Ultra) at three resolutions. The combo stands at rank 231 out of 3,700 tested combinations, placing it in the top 7% of configurations for this game. The CPU, with 12 cores and 24 threads clocked at 4.70 GHz base and 5.60 GHz boost, and the GPU, a GeForce RTX 4080 with 16 GB of GDDR6X memory, together deliver frame rates that span from 52 FPS at 4K Ultra to 432 FPS at 1080p Low. This article analyzes how the combination scales with resolution, what the measured numbers indicate about the limiting component, and which settings offer the best playable experience.

Resolution Scaling

The measured FPS values show a clear trend: as resolution increases from 1080p to 4K, average frame rates decline across every preset, but the degree of drop varies by quality level. At 1080p, the Low preset reaches 432 FPS, Medium 304 FPS, High 235 FPS, and Ultra 156 FPS. Stepping up to 1440p, these numbers fall to 275, 194, 150, and 99 FPS respectively. At 4K (3840×2160), the averages drop to 145, 102, 79, and 52 FPS for Low through Ultra. This pattern indicates that the RTX 4080’s GPU throughput becomes the dominant limiting factor at higher resolutions—while the CPU can saturate low-resolution queues at high frame rates, the GPU workload per pixel forces scaling down quickly.

• 1080p to 1440p: At Low, the average FPS falls from 432 to 275, a 36.4% reduction. At Medium, it drops from 304 to 194 (36.2%), at High from 235 to 150 (36.2%), and at Ultra from 153 to 99 (35.3%). This fairly uniform percentage loss suggests that resolution increases are being handled proportionally by both GPU and CPU, though the effective workload per frame doubles.
• 1440p to 4K: The drop is even steeper: Low goes from 275 to 145 (47.3% reduction), Medium from 194 to 102 (47.4%), High from 150 to 79 (47.3%), and Ultra from 99 to 52 (47.5%). The near-identical percentage drop across all presets indicates that once the resolution quadruples (from 1440p to 4K), the GPU becomes the bottleneck, because the CPU can already produce the maximum frame rate at 1440p for that load, but the GPU cannot keep up.

The fact that the FPS at 1080p Low is more than double that at 4K Low (432 vs 145) underscores the GPU-bound nature of 4K. At 1080p, the CPU is able to feed framerates above 400 FPS, suggesting the Ryzen 9 7900X has ample headroom for even high-refresh-rate e-sports displays. However, at 4K the RTX 4080’s shading and memory bandwidth become the limiting factor—even at Low settings, it cannot deliver more than 145 FPS average.

How This Combo Ranks

The database places this CPU-GPU pair at rank 231 out of 3,700 tested combos in Fortnite. That is the top 6.2% of configurations—a strong showing, but not the absolute top tier. The ranking implies that there are other combinations that achieve higher frame rates, but those are likely using more powerful GPUs (e.g., the RTX 4080 SUPER or other top-end models) or CPUs with higher single-thread performance, since Fortnite is not heavily threaded.

When looking at the individual components, the CPU’s average benchmark score of 53,288 places it at the 91st percentile of all CPUs, and it is essentially a dead heat with the closest competing models: the AMD EPYC 7313P (average score 53,206, 0.2% ahead) and the Intel Core i7-14700F (average 53,620, 0.6% behind). The GPU’s passmark score of 34,457 and its 86th percentile among all GPUs are within a whisker of the RTX 4080 SUPER (54,209, +0.1%) and other high-end cards—though the AMD Radeon RX 6900S and RX 6000-series appear to be slightly higher in the raw 3DMark scores, but their actual game performance is not listed here. The combined performance, however, results in a GPU-bound experience at 4K, so the GPU’s ranking has a stronger influence on overall Fortnite performance than the CPU’s does.

FAQ

Q: What is the maximum average FPS the Ryzen 9 7900X + RTX 4080 combo achieves in Fortnite at 1080p?

A: The highest measured average is 432 FPS at 1080p on Low settings. This suggests that the CPU is the limiting factor at this resolution, as the GPU is not yet saturated.

Q: What is the average FPS at 4K with Ultra settings?

| 1920×1080 (1080p) | Medium | 304 | 259 | 350 |

| 1920×1080 (1080p) | High | 236 | — | — |

| 1920×1080 (1080p) | Ultra | 153 | — | — |

Note that the Ultra settings at 1080p deliver 156 FPS, while the Medium preset gives 304 FPS – a 48% increase in frame rate from Ultra to Medium, at the cost of reduced visual fidelity. At 4K, the ratio is even larger: 145 (Low) vs 52 (Ultra) is a 179% difference.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor based on the Zen 4 (Raphael) architecture, fabricated on a 5 nm process. Its base clock is 4.70 GHz and boost up to 5.60 GHz, with a TDP of 170 W. The CPU sports 64 MB of shared L3 cache and a 64 KB L1 per core, which provides plenty of cached data for rendering input. In three more complete CPU benchmarks, the 7900X scores 29,300 in Cinebench R23 multi-core and 2,016.5 single-core, which places it in the top 10 % of processors via percentile of 91% of all CPUs.

In Fortnite, the game has had varying thread fidelity; its core engine is not heavily threaded, so single-thread performance is more critical than the number of cores. The single-core score of 2,016.5 in Cinebench R23 is a direct indicator of its single-thread capability, and it contributes heavily to the 1080p Low frame rate of 432 FPS. However, as resolution increases, the GPU takes over, and the CPU's load is lessened, so the same CPU can still manage to provide frame rates between 52 and 145 at 4Kp, showing that even at 4Kp, the CPU is not the bottleneck—since the FPS drop more matches the pixel increase than CPU limits.

The 12-core design does not hurt in this game; no thread is a limiting factor. Its high boost of 5.60 GHz and base 4.70 GHz are both high, which contribute to its position at the 91st percentile of all CPUs. The CPU’s performance is also tied closely to three rivals: the EPYC 7313P (maybe a server chip), the Xeon (5106?), and the i7-14700F. The difference in average benchmark scores is within 0.6% each, meaning the CPU is essentially an equal among its peers.

In practice, gamers can expect that any of these four CPUs would deliver similar Fortnite performance when paired with the same GPU at 1080p and at 1440p, but the higher core counts may not matter much.

Settings Recommendations

Based on the measured FPS, the optimal resolution and setting depends on the display's refresh rate and the player’s frame-time sensitivity.

• 1080p (1920×1080): For high-refresh-rate monitors (165 Hz or higher), the Low preset delivers the highest average at 432 FPS, but Medium provides still-excellent 304 FPS with a visual quality upgrade. Ultra at 153 also satisfies a 144 Hz display, and the difference between Low and Ultra is more than 100 FPS. If you want a balanced experience, Medium is the best pick—it pushes above 300 FPS, keeping up with any 240 Hz monitor, and it has a measured minimum of 259 FPS, ensuring no severe stutter. High gives 236 FPS, which also hit 240 Hz screens but at lower margins.

• 1440p (2560×1440): Typical high-refresh 1440p monitors are 144 Hz or 165 Hz. The High preset averages 149 FPS, which meets that 144 Hz target, but not for 165 Hz. Medium provides 194 FPS, comfortably reaching 165 Hz, and it has a reported minimum of 165 FPS—exactly meeting that refresh gap. Ultra is only 99 FPS, so unless your monitor is 60 Hz, it's not advisable. Low gives 275 FPS, but that may look noticeably worse. For 1440p, Medium is the sweet spot: it provides a 194 FPS average with a 165 FPS floor, which pairs well with 165 Hz displays. If you prioritize visual fidelity, High (149 FPS) is still playable but 144 Hz screens will show dips.

• 4K (3840×2160): At 4K, even the RTX 4080 can only sustain above 100 FPS with the Low preset (145 FPS). Medium gives 102 FPS average, with a minimum of 87 – that is enough for 60 Hz TVs but not 120 Hz. Ultra yields only 52 FPS, which is playable but may feel sluggish. Given the low frame counts, the Medium preset is the best combination of visual quality (compared to Low) and playable fifty‑99 FPS, since it delivers a smooth experience on a 60 Hz display and also has a minimum of 87 FPS, avoiding the worst drops. High or Ultra fall below a 60 FPS target.

FAQ

Q: Why is there a difference in FPS between Low and Ultra at 1080p?

A: The frame rate drops from 432 to 153, a 179% reduction. This is because the Ultra preset increases lighting, shadows, and effects significantly, placing higher demand on both the CPU and GPU, but the CPU still has headroom as evidenced by the 432 FPS at Low.

Q: Does the CPU get overwhelmed at 1080p Low?

A:** No, the 12-core 24-thread Ryzen 9 7900X can feed 432 FPS at 1080p Low, which is above any current monitor's refresh rate. This suggests the CPU is not the limiting factor at that resolution.

Q: How does the combo rank among others in Fortnite?

A:** The combo is 231st out of 3,700 measured combos, placing it in the top 6.2% of configurations. That position shows it’s a very capable pairing, though not the absolute fastest.

Q: Can this combo maintain a 144 Hz 4K experience?

No. The highest 4K preset average is 145 FPS (Low) and 102 FPS (Medium). Neither passes 144 FPS consistently, so 4K but only 60 Hz is the realistic ceiling.

Q: What are the CPU's architectural details relevant to Fortnite? For battle royale, the priority single-thread speed is high (boost to 5.60 GHz) and a mature instruction set. The 5 nm TSMC process gives fast switching, and the 64 MB L3 cache increases hit rates.

Q: What are the advised power requirements?

A:** The TDP is 170 W for the CPU and 320 W for the GPU, with a total system PSU of 700 W suggested, according to the GPU specification.
