GPU Role

The GeForce RTX 5070 brings 12 GB of GDDR7 memory across a 192-bit bus, delivering 672.0 GB/s of bandwidth. The memory clock runs at 1750 MHz with 28 Gbps effective speed. These memory specifications are highly relevant to Fortnite's performance scaling, as the game's texture streaming and asset loading can benefit substantially from high memory bandwidth. The GPU operates at a base clock of 2325 MHz and boosts to 2512 MHz, which is a relatively modest boost ratio, suggesting the card is designed to sustain high clocks under load.

The GPU's 6144 shading units, 192 texture mapping units, and 80 render output units provide the raw compute throughput needed for Fortnite's stylized but demanding visuals. The card achieves 30.87 TFLOPS of FP32 performance and 201.0 GPixel/s pixel rate. The 48 RT cores and 192 tensor cores also position this card well for Fortnite's evolving use of ray tracing and upscaling features. The data shows the GPU's PassMark G3D score of 29137 and its percentile rank of 83 versus all GPUs, which contextualizes its performance class. In Fortnite specifically, the measured results show the GPU scales strongly from Low to High settings at 1080p, but the Ultra preset causes a dramatic performance cliff, suggesting the RTX 5070's capabilities are stretched by the highest quality settings even at lower resolutions.

CPU Role

The Intel Core i5-12400F provides 6 cores and 12 threads based on the Alder Lake architecture, manufactured on Intel's 10 nm process. It operates with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. The CPU's cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 18 MB of shared L3 cache. This configuration supports DDR4 and DDR5 memory in dual-channel mode, though the fact pack does not specify which memory type was used in these benchmark runs.

The CPU's single-thread performance is particularly relevant for Fortnite, which is known to be sensitive to single-core speed in many scenarios. The 3DMark single-thread score of 909 and the Cinebench R23 single-core score of 2332 indicate strong per-core performance. The multi-threaded results show a Cinebench R23 multi-core score of 16518, which demonstrates the 12 threads provide solid scaling for games that utilize multiple cores. The CPU's PassMark single-thread score of 3481 and multi-thread score of 19433 place it near the Intel Core i7-8700K in aggregate performance, with a delta of just 0.1%. This is notable because the i7-8700K is an older, higher-end part, suggesting the i5-12400F offers competitive processing power for gaming workloads. The CPU's 77th percentile ranking versus all CPUs indicates it is not a bottleneck for most gaming scenarios, though the data suggests it may limit maximum frame rates in Fortnite's least demanding settings.

Resolution Scaling

The measured data reveals how this combination scales across resolutions. At 1080p with Low settings, the average FPS is 363.6. Stepping up to 1440p Low drops the average to 229.6, a 36.9% reduction. Moving to 4K Low yields 121.3 FPS, which is 47.2% lower than 1440p and 66.6% lower than 1080p. This scaling pattern indicates the GPU is the primary driver of performance at lower settings, as the CPU has enough headroom to feed frames at these rates.

The scaling at High settings tells a different story. At 1080p High, the average is 201.3 FPS. At 1440p High, it drops to 129.4 FPS, a 35.7% reduction. At 4K High, the average falls to 67.3 FPS, which is 48.0% lower than 1440p and 66.6% lower than 1080p. The percentage drops between resolutions are remarkably consistent across Low and High settings, suggesting the GPU is the limiting component throughout. However, the Ultra preset shows a steeper decline: 131 FPS at 1080p, 80.6 FPS at 1440p (a 38.5% drop), and 43.5 FPS at 4K (a 46.0% drop from 1440p). This steeper decline at Ultra suggests the additional graphical features in this preset place extra strain on the GPU's memory subsystem and compute units.

The data implies that at 1080p Low, the system is likely approaching the CPU's maximum frame delivery capability, given the extremely high 363.6 FPS average. The i5-12400F's single-thread performance becomes more relevant at these frame rates, as the CPU must process game logic and draw calls quickly enough to keep up with the GPU's rendering speed.

Settings Recommendations

The measured FPS rows provide clear guidance on which preset offers the best balance of visual quality and performance. At 1080p, the High preset delivers 201.3 FPS average, which is well above the refresh rate of most high-refresh monitors. The Ultra preset drops to 131 FPS, which is still playable but represents a 34.9% performance penalty. The data suggests High is the optimal preset at 1080p, as it maintains excellent frame rates while providing better visual quality than Medium's 254.5 FPS.

At 1440p, High settings produce 129.4 FPS, which is suitable for 120Hz monitors. The Medium preset at 163.8 FPS offers additional headroom for competitive play, while Ultra at 80.6 FPS is still above 60 FPS but significantly lower. The recommendation at 1440p depends on the user's monitor refresh rate, but the High preset appears to be the sweet spot for visual fidelity and performance.

At 4K, High settings yield 67.3 FPS, which is just above the 60 FPS threshold. The Medium preset at 86.6 FPS provides more comfortable margins above 60 FPS, while Ultra at 43.5 FPS is below the threshold and not recommended for smooth gameplay. Low settings at 4K produce 121.3 FPS, which is surprisingly high and suggests the GPU has significant headroom when visual effects are minimized. For 4K users, the Medium preset offers the best combination of acceptable frame rates and visual quality, as it maintains 86.6 FPS while providing more detail than Low settings.

Measured FPS Breakdown

The complete dataset of measured frame rates shows the system's performance across all tested configurations.

At 1920x1080, the average FPS ranges from 363.6 at Low settings to 131 at Ultra. Medium settings produce 254.5 FPS, while High settings yield 201.3 FPS. The progression from Low to Ultra shows a 63.9% reduction in frame rate, demonstrating the substantial performance cost of the Ultra preset's additional effects.

At 2560x1440, the results scale down proportionally. Low settings achieve 229.6 FPS, Medium produces 163.8 FPS, High delivers 129.4 FPS, and Ultra drops to 80.6 FPS. The difference between Low and Ultra at this resolution is 64.9%, similar to the 1080p scaling.

At 3840x2160, the performance becomes more constrained. Low settings still achieve 121.3 FPS, which is impressive for a 4K resolution. Medium settings produce 86.6 FPS, High settings yield 67.3 FPS, and Ultra falls to 43.5 FPS. The gap between Low and Ultra at 4K is 64.1%, consistent with the other resolutions.

The data shows that the RTX 5070's 12 GB of GDDR7 memory and 672.0 GB/s bandwidth is sufficient to handle Fortnite's texture requirements even at 4K, as evidenced by the playable frame rates at High settings. The GPU's 48 RT cores may contribute to the Ultra preset's performance cost, as Fortnite's Ultra settings likely enable additional ray tracing features that stress these dedicated cores. The CPU's role becomes more apparent at lower resolutions and settings, where frame rates exceed 200 FPS and the i5-12400F's 6 cores and 12 threads must process game logic at increasingly rapid intervals.
