# Fortnite with AMD Ryzen 9 7900X + NVIDIA GeForce RTX 4070

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 4070 produces a wide spread of frame rates across Fortnite's four preset levels and three resolutions. At 1080p the combination delivers between 122 and 338 FPS depending on settings, while 1440p spans 77 to 215 FPS, and 4K drops to a 41 to 113 FPS range. The recorded data shows a system that is clearly capable of high-refresh gameplay at mainstream resolutions but becomes increasingly GPU-bound as pixel count rises.

Resolution Scaling

The measured FPS data reveals how the balance between CPU and GPU shifts across resolutions. At 1920x1080 with Low settings, the system produces 338 FPS average, which is the highest recorded value in the entire dataset. Moving to 2560x1440 at the same Low preset reduces the average to 215 FPS, a drop of 123 FPS or roughly 36 percent. At 3840x2160 Low, the average falls further to 113 FPS, which is about 33 percent below the 1440p figure and 67 percent below the 1080p figure.

The Medium preset shows a similar pattern. At 1080p the average is 238 FPS with a minimum of 202 FPS and a maximum of 274 FPS. At 1440p Medium, the average drops to 151 FPS with a minimum of 129 FPS and a maximum of 174 FPS. At 4K Medium, the average is 80 FPS with a minimum of 68 FPS and a maximum of 92 FPS. The scaling from 1440p to 4K at Medium is a 71 FPS reduction, which is a 47 percent loss, while the 1080p to 1440p step costs 87 FPS, a 37 percent loss.

High settings follow the same trend. The 1080p High average is 184 FPS, 1440p High is 117 FPS, and 4K High is 62 FPS. The 1080p to 1440p transition removes 67 FPS, while the 1440p to 4K transition removes 55 FPS. Ultra settings produce the lowest frame rates at every resolution: 122 FPS at 1080p, 77 FPS at 1440p, and 41 FPS at 4K.

The pattern across all four presets indicates that scaling is not linear. The largest absolute FPS losses occur when moving from 1080p to 1440p at Low and Medium settings, which suggests that at those settings the CPU and GPU combination is still capable of very high frame rates and the additional pixel workload has a pronounced effect. At 4K, the FPS values are much lower, and the gap between presets narrows in absolute terms, indicating that the GPU becomes the dominant limiting factor.

The 4K Ultra result of 41 FPS is the only recorded value below 60 FPS in the entire dataset, and it sits well below the 4K High result of 62 FPS. The data shows that the RTX 4070 can sustain playable frame rates at 4K when settings are kept at High or below, but Ultra settings at 4K push the GPU past its comfortable operating point.

GPU Role

The NVIDIA GeForce RTX 4070 uses the AD104 chip built on a 5 nm process with 35,800 million transistors and a die size of 294 mm². The GPU has 12 GB of GDDR6X memory on a 192 bit bus, delivering 504.2 GB/s of bandwidth. The memory clock is 1313 MHz with 21 Gbps effective data rate. The boost clock is 2475 MHz with a base clock of 1920 MHz.

The GPU's memory configuration is directly relevant to Fortnite's results at high resolutions. At 4K, the game must handle larger textures and more geometry, and the 12 GB frame buffer is sufficient for the measured presets, as the data shows no anomalous drops that would indicate memory capacity issues. The 504.2 GB/s bandwidth provides enough throughput for the 4K Medium result of 80 FPS and the 4K High result of 62 FPS. The 4K Ultra result of 41 FPS is more likely limited by the GPU's compute throughput rather than memory bandwidth.

The GPU's shading resources include 5888 shading units, 184 TMUs, 64 ROPs, 46 RT cores, and 184 tensor cores. The pixel rate is 158.4 GPixel/s and the texture rate is 455.4 GTexel/s. The FP32 compute is 29.15 TFLOPS. These figures explain why the GPU handles Low settings so efficiently. At 1080p Low, the system reaches 338 FPS, which is a very high frame rate but still below the theoretical maximum of the GPU, indicating that the CPU is also contributing to the ceiling.

The RTX 4070 produces a 3DMark Steel Nomad DX12 score of 3854, a Geekbench OpenCL score of 154858, a Geekbench Vulkan score of 174152, and a Passmark G3D score of 26927. The GPU's average benchmark score is 37648, placing it in the 81st percentile against all GPUs. Its nearest rivals in the database include the NVIDIA Tesla P4 with a score of 37628 and a delta of 0.1 percent, the AMD Radeon RX Vega 56 with 37507 and a delta of 0.4 percent, the NVIDIA GeForce RTX 4080 Mobile with 38135 and a delta of -1.3 percent, and the AMD Radeon PRO W6400 with 37157 and a delta of 1.3 percent.

Settings Recommendations

The measured FPS rows provide a clear picture of how each preset behaves on this hardware. The Low preset delivers the highest frame rates at every resolution: 338 FPS at 1080p, 215 FPS at 1440p, and 113 FPS at 4K. These numbers are far above the refresh rates of most displays, so the Low preset is only necessary if the user is chasing maximum frame rates on a very high refresh monitor.

The Medium preset offers a substantial visual improvement over Low while still maintaining high frame rates. At 1080p Medium the average is 238 FPS with a minimum of 202 FPS, so even the lowest recorded frame stays above 200 FPS. At 1440p Medium the average is 151 FPS with a minimum of 129 FPS, which is comfortably above 120 FPS. At 4K Medium the average is 80 FPS with a minimum of 68 FPS, which is playable but not ideal for competitive play.

The High preset reduces frame rates noticeably compared to Medium. At 1080p High the average is 184 FPS, at 1440p High it is 117 FPS, and at 4K High it is 62 FPS. The 1440p High result is close to 120 FPS, and the 4K High result barely clears 60 FPS. High settings provide better shadows, lighting, and texture detail than Medium, but the frame rate cost is significant at higher resolutions.

The Ultra preset produces the lowest frame rates: 122 FPS at 1080p, 77 FPS at 1440p, and 41 FPS at 4K. The 4K Ultra result falls below 60 FPS, which makes it unsuitable for smooth gameplay on this hardware. At 1080p Ultra the average of 122 FPS is still high, but the visual difference between High and Ultra in Fortnite may not justify the 62 FPS drop.

The best experience per the measured rows depends on the target display. For 1080p users, Medium provides the highest frame rates with a minimum above 200 FPS, while High still delivers 184 FPS average. For 1440p users, Medium is the optimal choice with a 151 FPS average and a 129 FPS minimum, while High at 117 FPS is acceptable for less competitive play. For 4K users, Low at 113 FPS is the only preset that stays well above 60 FPS, and Medium at 80 FPS is the highest quality option that remains playable.

How This Combo Ranks

The combination of the AMD Ryzen 9 7900X and the NVIDIA GeForce RTX 4070 ranks 864th out of 3700 tested combos in Fortnite. This places the system in the top 23 percent of all recorded configurations. The rank reflects the balance between the CPU and GPU, where the Ryzen 9 7900X provides a strong foundation and the RTX 4070 delivers competitive frame rates at mainstream resolutions.

The 864th rank out of 3700 combos indicates that many other configurations achieve higher Fortnite performance, but the majority of tested combos fall below this system. The measured data shows that the system is capable of very high frame rates at 1080p and strong performance at 1440p, with 4K being the weakest area. The rank is likely influenced by the 4K Ultra result of 41 FPS, which is the only sub-60 FPS value in the dataset, as well as the overall frame rate spread across all presets.

The RTX 4070's position in the GPU percentile ranking at 81 percent against all GPUs, combined with the Ryzen 9 7900X's 91 percent percentile against all CPUs, suggests that the CPU is relatively stronger than the GPU in this pairing. The measured Fortnite results reflect this imbalance at low resolutions, where the CPU has more influence, and at high resolutions, where the GPU becomes the bottleneck.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor from the 7000 series based on the Zen 4 architecture with the Raphael codename. It has a base clock of 4.70 GHz and a boost clock of 5.60 GHz, with 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. The CPU uses the AMD Socket AM5 platform, supports DDR5 memory on a dual-channel bus with 83.2 GB/s bandwidth, and features 24 PCIe Gen 5 lanes. The process node is 5 nm from TSMC, with 13,140 million transistors across a die size of 2x 71 mm².

The CPU's single-thread performance is strong, as shown by the 3DMark single-thread score of 1093 and the Cinebench R23 single-core score of 2016.5. The Passmark single-thread score is 4238. These numbers are relevant to Fortnite because the game's engine typically relies heavily on a few main threads for game logic and draw call submission. The high boost clock of 5.60 GHz gives the CPU a significant advantage in lightly threaded workloads.

The multi-thread performance is also substantial. The 3DMark max-thread score is 12536, the 3DMark 16-thread score is 10972, and the Cinebench R23 multicore score is 29300. The Passmark multithread score is 51406, and the Geekbench multicore score is 19267. These results show that the CPU can handle heavy parallel workloads, but Fortnite does not fully utilize all 24 threads, so the single-thread performance is more impactful for this game.

The CPU's average benchmark score is 53288, placing it in the 91st percentile against all CPUs. Its nearest rivals include the AMD EPYC 7313P with a score of 53206 and a delta of 0.2 percent, the Intel Xeon Phi 7290 with 53469 and a delta of -0.3 percent, the Intel Xeon 634 with 52974 and a delta of 0.6 percent, and the Intel Core i7-14700F with 53620 and a delta of -0.6 percent. The Ryzen 9 7900X sits within a tight cluster of these processors, with deltas of less than 1 percent in either direction.

In Fortnite, the CPU's role becomes more apparent at 1080p with Low settings, where the system reaches 338 FPS. This frame rate is high enough that the GPU is not the sole limiting factor, and the CPU's single-thread performance contributes to sustaining such high frame rates. At 4K with Ultra settings, the frame rate drops to 41 FPS, which is clearly GPU-bound, and the CPU's performance is not the bottleneck.

Measured FPS Breakdown

The spread from Low to Ultra at 1440p is 138 FPS, and the largest single drop is 64 FPS between Low and Medium.

At 3840x2160, the Low preset averages 113 FPS, the Medium preset averages 80 FPS with a minimum of 68 FPS and a maximum of 92 FPS, the High preset averages 62 FPS, and the Ultra preset averages 41 FPS. The spread from Low to Ultra at 4K is 72 FPS, and the largest single drop is 33 FPS between Low and Medium.

The Medium preset is the only setting that includes minimum and maximum FPS values in the measured data. At 1080p Medium, the minimum is 202 FPS and the maximum is 274 FPS, giving a range of 72 FPS. At 1440p Medium, the minimum is 129 FPS and the maximum is 174 FPS, giving a range of 45 FPS. At 4K Medium, the minimum is 68 FPS and the maximum is 92 FPS, giving a range of 24 FPS. The decreasing range at higher resolutions suggests that frame time variance is reduced when the GPU is more heavily loaded.

Comparing across resolutions at the same setting, the Low preset shows the largest absolute FPS drop from 1080p to 1440p at 123 FPS, while the Ultra preset shows the smallest drop at 45 FPS. The Medium preset drops 87 FPS from 1080p to 1440p and 71 FPS from 1440p to 4K. The High preset drops 67 FPS from 1080p to 1440p and 55 FPS from 1440p to 4K. These numbers confirm that the scaling penalties are proportionally larger at lower resolutions, where the system is less GPU-bound.
