Fortnite

The AMD Ryzen 7 9700X paired with the NVIDIA GeForce RTX 4070 produces a Fortnite performance profile that is heavily dictated by resolution and preset selection. The measured data reveals a component pairing that scales predictably from high-refresh 1080p play to playable 4K, with the GPU becoming the clear limiting factor as pixel count rises. This analysis breaks down the measured FPS across all combinations, the role of each component, and how this combo stacks up against the broader tested field.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals the expected shift in bottleneck. At 1080p Low, the combo achieves 334.4 FPS, but at 4K Low, that number falls to 111.1 FPS—a reduction of roughly 67%. This steep decline indicates that at lower resolutions, the CPU and GPU are both highly capable, but the rendering load at 4K overwhelms the RTX 4070’s throughput.

The scaling pattern across presets tells a similar story. At 1080p Ultra, the average FPS is 120.2, while at 4K Ultra it drops to 40.1 FPS—a 66.6% reduction. The consistency of this percentage drop across Low and Ultra presets suggests that the limiter is purely resolution-driven, not settings-driven. When moving from 1440p to 4K, the High preset falls from 115.6 FPS to 63.6 FPS (a 45% drop), while the Medium preset goes from 150.2 FPS to 82.9 FPS (a 44.8% drop). These near-identical relative declines strongly point to the GPU’s pixel fill rate and memory bandwidth as the constraining factors at 4K.

At 1080p, the data implies the CPU has headroom left. The jump from Low (334.4 FPS) to Medium (238.5 FPS) is a 28.7% drop, and from Medium to High (186.4 FPS) another 21.8% drop. These are large steps, but the absolute numbers remain high enough that the Ryzen 7 9700X’s 8 cores and 16 threads are not the primary limiter. The scaling from 1440p to 1080p at Low settings (213.9 FPS to 334.4 FPS, a 56.3% increase) shows that the GPU is still the main bottleneck even at 1440p, as the CPU can push far beyond 200 FPS in this title.

GPU Role

The RTX 4070’s 12 GB of GDDR6X memory on a 192-bit bus provides 504.2 GB/s of bandwidth. In Fortnite, this memory configuration appears sufficient for 1080p and 1440p, where the highest measured average is 334.4 FPS at 1080p Low. The card’s boost clock of 2475 MHz and base clock of 1920 MHz, combined with 5888 shading units, deliver the raw compute needed for these frame rates. The data shows that the GPU is the dominant factor at 4K, where even the Low preset only reaches 111.1 FPS, suggesting that the memory bandwidth and pixel rate (158.4 GPixel/s) are strained by the 3840x2160 resolution.

The difference between 1440p Ultra (76.6 FPS) and 1080p Ultra (120.2 FPS) is a 57% increase, which is larger than the 33% increase in pixel count (from 3.7 million to 2.1 million). This super-linear scaling indicates that the GPU’s texture rate (455.4 GTexel/s) and FP32 throughput (29.15 TFLOPS) are heavily taxed by the Ultra preset’s effects at higher resolutions. The card’s 64 ROPs appear to be a limiting factor for 4K Ultra, where the 40.1 FPS average is below the 60 FPS threshold for smooth gameplay.

Notably, the RTX 4070’s percentile rank versus all GPUs is 81, and its average benchmark score is 37283. In Fortnite specifically, the 4K High result of 63.6 FPS shows that the card can handle modern titles at 4K with some settings compromises, but the 4K Ultra result of 40.1 FPS demonstrates that max settings are reserved for lower resolutions. The GPU’s 46 ray tracing cores are present but not directly measured in this dataset, so their impact on Fortnite’s ray-traced modes cannot be quantified here.

Settings Recommendations

The measured rows offer a clear hierarchy for optimal play. At 1080p, the Medium preset delivers 238.5 FPS, which is a 72.5% improvement over the High preset’s 186.4 FPS. The jump from Medium to Low (334.4 FPS) is another 40% gain, but the visual compromise may not justify it for most users. For competitive play at 1080p, the Low preset’s 334.4 FPS provides the highest headroom, while Medium offers a balance of visual fidelity and speed.

At 1440p, the Medium preset’s 150.2 FPS is the standout choice, as it sits comfortably above the High preset’s 115.6 FPS while maintaining a 60 FPS margin over the Ultra preset’s 76.6 FPS. The data suggests that 1440p Medium is the sweet spot for high-refresh monitors. For 4K, the Low preset’s 111.1 FPS is the only option that clears the 100 FPS mark, while Medium (82.9 FPS) and High (63.6 FPS) provide playable but not high-refresh experiences. The Ultra preset at 4K (40.1 FPS) is not recommended for any scenario, as it falls below the 60 FPS threshold.

The best experience per the measured rows depends on the target refresh rate. For 144Hz displays, 1080p Medium (238.5 FPS) or 1440p Medium (150.2 FPS) are the only presets that exceed that target. For 60Hz displays, 4K Medium (82.9 FPS) offers a smooth experience with better visuals than Low. The data consistently shows that Medium is the most balanced preset across all resolutions, providing FPS that is 19-29% higher than High while retaining most visual quality.

Measured FPS Breakdown

At 1920x1080, the results are as follows: Low hits 334.4 FPS, Medium drops to 238.5 FPS, High falls to 186.4 FPS, and Ultra bottoms out at 120.2 FPS. The step from Low to Medium is the largest absolute drop (95.9 FPS), while the step from High to Ultra is 66.2 FPS. This pattern suggests that the Ultra preset adds effects that disproportionately tax the GPU.

At 2560x1440, Low achieves 213.9 FPS, Medium reaches 150.2 FPS, High manages 115.6 FPS, and Ultra is limited to 76.6 FPS. The percentage drops between presets are relatively consistent: Low to Medium is 29.8%, Medium to High is 23.0%, and High to Ultra is 33.7%. The Ultra preset at 1440p shows the steepest relative decline, indicating a heavy load on the GPU’s 29.15 TFLOPS.

At 3840x2160, Low produces 111.1 FPS, Medium drops to 82.9 FPS, High falls to 63.6 FPS, and Ultra plummets to 40.1 FPS. The gap between High and Ultra at 4K is 23.5 FPS, which is smaller in absolute terms than at lower resolutions but represents a 37% reduction. The 4K Low result of 111.1 FPS is notable as it is higher than the 1440p Ultra result of 76.6 FPS, showing that resolution has a greater impact on performance than preset quality.

CPU Role

The AMD Ryzen 7 9700X features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.50 GHz. Its Zen 5 architecture on a 4 nm process provides a single-thread 3DMark score of 1280 and a max-thread score of 9771. In Fortnite, the CPU’s role is evident in the 1080p Low result of 334.4 FPS, which is the highest measured average. The 16 threads allow for smooth handling of the game’s background tasks, while the 32 MB of shared L3 cache reduces memory latency.

The CPU’s benchmark scores correlate with the FPS data. The Cinebench R23 multi-core score of 31588 and single-core score of 4459 suggest that the CPU is not a bottleneck at any resolution tested. At 4K Ultra, where the GPU is clearly the limiter (40.1 FPS), the CPU still has headroom, as the 8 cores are not fully saturated. The Ryzen 7 9700X’s 89th percentile ranking versus all CPUs, with an average benchmark score of 36029, places it slightly above the Intel Core i5-14500HX (35940, +0.2% delta) and slightly below the Intel Core Ultra 9 185H (36165, -0.4% delta). These rival comparisons show that the CPU is competitive but not leading in raw compute.

In Fortnite specifically, the CPU’s 5.50 GHz boost clock is likely the key factor for high-FPS scenarios. The 1080p Low result of 334.4 FPS demonstrates that the CPU can drive frame rates well beyond typical 240Hz displays. The data indicates that the CPU’s role diminishes as resolution increases, with the GPU taking over as the primary performance determinant.

How This Combo Ranks

This Ryzen 7 9700X + RTX 4070 combination ranks 399 out of 1564 tested combos in Fortnite, placing it in the top 25.5% of all configurations. This rank reflects the balance between the CPU’s strong single-thread performance and the GPU’s high-end 40-series capabilities. The combo’s position suggests that it outperforms most mid-range setups but falls short of top-tier configurations that pair higher-end CPUs with RTX 4080 or 4090-class GPUs.

The ranking is consistent with the measured FPS data. At 1080p, the combo’s 334.4 FPS Low result is exceptional, but the 4K Ultra result of 40.1 FPS pulls the overall standing down relative to combos with more powerful GPUs. The 1440p Medium result of 150.2 FPS is a strong showing, indicating that this combo is well-suited for 1440p high-refresh gaming. The rank of 399 out of 1564 means that approximately 74.5% of tested combos are slower, but the top 25.5% (roughly 390 combos) achieve higher average FPS, likely through more powerful GPUs or higher-end CPUs.
