Fortnite

Resolution Scaling

The measured FPS data for Fortnite on this AMD Ryzen 9 7900X + NVIDIA GeForce RTX 5070 combo reveals a clear pattern of scaling from 1080p to 4K, with the GPU becoming progressively more dominant as resolution increases. At 1920x1080 with Low settings, the combo delivers 365 FPS, but this drops to 230.5 FPS at 2560x1440 and further to 122.6 FPS at 3840x2160. That represents a 66.4% reduction from 1080p to 4K at Low settings, indicating that the rendering load is scaling heavily with pixel count.

The scaling behavior changes with settings. At Ultra settings, the frame rate falls from 130.3 FPS at 1080p to 85.4 FPS at 1440p, then to 42.8 FPS at 4K. The drop from 1440p to 4K at Ultra is a 49.9% reduction, which is steeper than the 34.5% drop from 1080p to 1440p. This suggests that at Ultra settings, the RTX 5070 is being pushed to its limits at 4K, with the 12 GB GDDR7 memory and 672.0 GB/s bandwidth becoming a potential constraint alongside the GPU's compute throughput.

At Medium settings, the scaling is more linear: 254.8 FPS at 1080p, 164.9 FPS at 1440p, and 87.9 FPS at 4K. The 1080p to 1440p drop is 35.3%, while the 1440p to 4K drop is 46.7%. High settings show a similar trend, with 196.6 FPS at 1080p, 126.7 FPS at 1440p, and 64.8 FPS at 4K. The data indicates that at lower settings, the CPU's 12 cores and 24 threads are more involved, allowing the GPU headroom to push higher frame rates. At 1080p Low, the 365 FPS result is likely approaching the CPU's ceiling for this game, given that the Ryzen 9 7900X has a boost clock of 5.60 GHz and a single-thread benchmark score of 1093 in 3dmark.

The limiting component shifts as resolution climbs. At 1080p, the gap between Low (365 FPS) and Ultra (130.3 FPS) is 2.8x, which is substantial and suggests the GPU is still the primary factor even at lower resolutions. However, the relatively modest gains from Medium to Low at 1080p (254.8 to 365 FPS) indicate that CPU performance is beginning to cap the absolute ceiling. At 4K, the spread narrows in relative terms: Ultra achieves 42.8 FPS while Low reaches 122.6 FPS, a 2.9x difference that is almost identical to the 1080p spread. This points to the RTX 5070's 30.87 TFLOPS FP32 compute being the dominant constraint across all settings, with the CPU rarely becoming the bottleneck except at the very highest frame rates.

FAQ

How This Combo Ranks

The combo's rank of 322 out of 1564 tested combos places it in the upper tier of configurations for Fortnite. This ranking reflects the combined capability of the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 5070, both of which are strong performers in their respective categories. The CPU ranks at the 93rd percentile among all CPUs, with an average benchmark score of 50556. Its nearest rivals include the Intel Core Ultra 5 235 with an average score of 50598 and a delta of -0.1%, the AMD Ryzen 9 5900XT at 50738 with a -0.4% delta, and the Intel Core i7-13850HX at 50827 with a -0.5% delta. The Intel Core i9-13980HX is the closest competitor at 50944, just 0.8% higher.

The GPU ranks at the 83rd percentile among all GPUs, with an average benchmark score of 41687. Its nearest rivals show mixed results: the AMD Radeon Pro 5300 scores 41610 with a delta of 0.2%, meaning the RTX 5070 is slightly behind. The NVIDIA Tesla M40 scores 41897 with a -0.5% delta, indicating the RTX 5070 is ahead. The NVIDIA GeForce RTX 3090 scores 41441 with a 0.6% delta, and the AMD Radeon Pro 580X scores 41991 with a -0.7% delta. These close margins suggest the RTX 5070 sits in a competitive performance band, but for Fortnite specifically, the combo's rank of 322 out of 1564 demonstrates that the pairing is well-suited to the game's demands.

The rank is particularly strong given that Fortnite is a competitive title where high frame rates matter. The measured FPS data shows that the combo can deliver over 200 FPS at 1440p with Low and Medium settings, and over 100 FPS at 4K with Low settings. This places it ahead of many other combos that might have stronger raw benchmark scores but struggle with Fortnite's particular engine characteristics. The 12-core CPU with 24 threads and 64 MB of shared L3 cache provides ample processing power, while the RTX 5070's 6144 shading units and 192 TMUs handle the game's rendering efficiently.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 365 FPS, Medium produces 254.8 FPS, High produces 196.6 FPS, and Ultra produces 130.3 FPS. The scaling from Low to Ultra is a 64.3% reduction, showing that the game's higher settings place significant additional load on the GPU. The gap between Medium and Low is 110.2 FPS, while the gap between High and Medium is 58.2 FPS, and between Ultra and High is 66.3 FPS.

At 2560x1440, the results are lower but still robust. Low settings achieve 230.5 FPS, Medium achieves 164.9 FPS, High achieves 126.7 FPS, and Ultra achieves 85.4 FPS. The reduction from 1080p to 1440p is 36.8% at Low, 35.3% at Medium, 35.6% at High, and 34.5% at Ultra. This consistency indicates that the scaling penalty is roughly uniform across settings, though Ultra shows a slightly smaller percentage drop, suggesting the CPU is providing relatively more support at higher settings.

At 3840x2160, the frame rates drop significantly. Low settings produce 122.6 FPS, Medium produces 87.9 FPS, High produces 64.8 FPS, and Ultra produces 42.8 FPS. The reduction from 1440p to 4K is 46.8% at Low, 46.7% at Medium, 48.9% at High, and 49.9% at Ultra. The percentage drops are larger than those from 1080p to 1440p, confirming that the GPU becomes the primary bottleneck at 4K. The 4K Ultra result of 42.8 FPS is the only measured value below 60 FPS, and it indicates that this combo is not suitable for 4K Ultra gameplay in Fortnite without additional optimizations.

GPU Role

The NVIDIA GeForce RTX 5070 plays a central role in this combo's Fortnite performance, particularly at higher resolutions and settings. The GPU features 12 GB of GDDR7 memory on a 192-bit bus, providing 672.0 GB/s of bandwidth. This memory configuration is sufficient for Fortnite at 1080p and 1440p, where the game's textures and effects are well within the 12 GB capacity. At 4K Ultra, however, the memory bandwidth and capacity may become limiting factors, as evidenced by the 42.8 FPS result.

The GPU's clock speeds are notable: a base clock of 2325 MHz and a boost clock of 2512 MHz, with memory running at 1750 MHz (28 Gbps effective). These clocks, combined with the 5 nm process node and 31,100 million transistors, allow the RTX 5070 to achieve 30.87 TFLOPS of FP32 compute. This raw compute power is what drives the high frame rates at 1080p and 1440p, where the GPU can operate near its peak efficiency.

The RTX 5070's benchmark results place it in a competitive position. Its Passmark G3D score of 29137 and Passmark GPU compute score of 15787 are strong, and its average benchmark score of 41687 puts it at the 83rd percentile. The nearest rivals, including the AMD Radeon Pro 5300 and NVIDIA Tesla M40, show that the RTX 5070 is slightly ahead of some and slightly behind others, but in Fortnite specifically, the measured FPS data demonstrates that the GPU's architecture is well-matched to the game's requirements.

The GPU's 48 RT cores and 192 tensor cores are not heavily utilized in Fortnite's standard rendering path, but they contribute to the card's overall versatility. The 80 ROPs and 192 TMUs handle the final pixel output and texture filtering, which are critical for the game's visual quality settings. The 201.0 GPixel/s pixel rate and 482.3 GTexel/s texture rate provide the throughput needed for high-resolution rendering. At 4K, the pixel rate becomes a limiting factor, which explains why the frame rates drop so sharply compared to 1440p. The GPU's 250 W TDP and suggested 600 W PSU indicate that power delivery is not a constraint for this combo, allowing the card to sustain its boost clock during extended gaming sessions.
