Fortnite

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 4070 is a formidable combination for Fortnite, capable of delivering high frame rates across all tested resolutions. The benchmark data shows this combo ranks 374th out of 1564 tested combinations, placing it in the top 24% of all systems. The measured FPS figures reveal a system that is overwhelmingly GPU-bound at higher resolutions, but becomes increasingly CPU-sensitive at 1080p with lower settings, where frame rates exceed 300 FPS.

CPU Role

The Intel Core i5-12400F provides the computational foundation for this Fortnite configuration. With 6 cores and 12 threads, this Alder Lake processor operates at a base clock of 2.50 GHz and boosts up to 4.40 GHz. The processor's 18 MB of shared L3 cache and 1.25 MB per-core L2 cache help maintain consistent performance during intense battle royale action. The CPU's benchmark results show a PassMark multithread score of 19433 and a single-thread score of 3481, with a Cinebench R23 multicore score of 16518 and single-core score of 2332.

The CPU's performance percentile sits at 77, meaning it outperforms 77% of all tested processors. Its nearest rival, the Intel Core i7-8700K, scores nearly identically with an average benchmark score of 19210 versus the i5-12400F's 19221, a delta of just 0.1%. This close comparison indicates that the i5-12400F delivers exceptional value in its performance class, matching an older high-end processor while offering modern architecture benefits.

In Fortnite, the CPU's influence becomes most apparent at 1080p with Low settings, where the measured average FPS reaches 334.4. This extreme frame rate suggests the processor can feed the GPU with data faster than the graphics card can render at lower resolutions. The 3DMark single-thread score of 909 and multi-thread score of 5912 indicate the CPU has sufficient raw throughput for the game's physics and simulation workloads, even when pushing beyond 300 FPS.

GPU Role

The NVIDIA GeForce RTX 4070 serves as the primary rendering engine, equipped with 12 GB of GDDR6X memory on a 192-bit bus delivering 504.2 GB/s of bandwidth. The GPU operates at a base clock of 1920 MHz with a boost clock of 2475 MHz, and its memory runs at 1313 MHz (21 Gbps effective). Built on the Ada Lovelace architecture with 5888 shading units, 184 TMUs, and 64 ROPs, this GPU achieves a PassMark G3D score of 26927 and a 3DMark Steel Nomad DX12 score of 3854.

The GPU's percentile ranking of 81 places it above 81% of all tested graphics cards. Its nearest competitor, the AMD Radeon RX Vega 56, scores 37507 on average compared to the RTX 4070's 37283, a delta of -0.6%. Interestingly, the RTX 4070's closest rivals include the NVIDIA GeForce MX570 A and RTX 4080 Mobile, with deltas of -1.9% and -2.2% respectively, though these comparisons highlight the desktop GPU's competitive positioning.

The GPU's 12 GB VRAM capacity proves sufficient for Fortnite's Ultra settings at 4K, where the measured average FPS drops to 41.2. The graphics card's FP32 performance of 29.15 TFLOPS and texture rate of 455.4 GTexel/s enable smooth rendering of the game's vibrant environments. The ray tracing cores and tensor cores, while not directly measured in this benchmark, support the game's advanced visual features when enabled.

Resolution Scaling

The measured FPS data reveals clear scaling patterns across resolutions. At 1080p with Low settings, the system achieves 334.4 FPS average, which drops to 214 FPS at 1440p (-36%) and further to 111.1 FPS at 4K (-48% from 1440p). This substantial drop indicates the GPU becomes the limiting factor as resolution increases, with the CPU's headroom at 1080p allowing frame rates far beyond what most displays can show.

The High settings preset shows a similar but less dramatic scaling pattern: 183.9 FPS at 1080p, 118.2 FPS at 1440p (-36%), and 62.2 FPS at 4K (-47% from 1440p). The consistent percentage drops across settings suggest the system maintains a balanced workload distribution, with the GPU handling the increased pixel count proportionally.

The most revealing data point comes from the Ultra settings, where 4K performance drops to 41.2 FPS, below the 60 FPS threshold commonly considered ideal for competitive play. This represents a 66% reduction from the 1080p Ultra result of 123 FPS. The scaling from Medium to High to Ultra at 4K (79.2, 62.2, and 41.2 FPS respectively) shows that each settings tier costs approximately 20-25% performance, confirming the GPU's dominance in determining frame rates at higher resolutions.

Settings Recommendations

For 4K gaming, the data indicates that High settings provide the best balance of visual quality and performance, with 62.2 FPS average. This exceeds the 60 FPS threshold while maintaining acceptable visual fidelity. Medium settings at 4K offer 79.2 FPS and represent a solid option for players prioritizing smoothness, while Low settings at 4K achieve 111.1 FPS but sacrifice visual quality significantly. Ultra settings at 4K, at 41.2 FPS, fall below playable thresholds for most users.

At 1440p, the High preset delivers 118.2 FPS, which is excellent for competitive play on high-refresh-rate monitors. The Medium preset at 154.1 FPS offers a substantial performance boost with minimal visual compromise, making it the recommended choice for players with 144Hz displays. Low settings at 1440p produce 214 FPS, which exceeds the refresh rate of most monitors but indicates the system has significant headroom.

For 1080p gaming, all settings presets exceed 120 FPS, with Low achieving 334.4 FPS, Medium at 239.6 FPS, High at 183.9 FPS, and Ultra at 123 FPS. The High preset at 183.9 FPS offers the best balance for competitive play, providing excellent visual quality while maintaining frame rates well above the 144Hz threshold. Ultra at 1080p, at 123 FPS, still provides smooth gameplay for most users and represents the best visual experience without sacrificing playability.
