Fortnite

The Intel Core i5-12400 paired with the NVIDIA GeForce RTX 5070 delivers a Fortnite experience that is heavily dependent on resolution and quality settings. Across the measured data, the combination shows a clear shift from being partially CPU-bound at lower resolutions to firmly GPU-bound at 4K. The most striking result is at 1080p Low, where the combination achieves 366.2 FPS, indicating significant headroom that is likely constrained by the CPU's single-thread performance rather than the GPU's capabilities.

Resolution Scaling

The performance drop from 1080p to 4K is substantial and reveals the bottleneck dynamics. At 1080p High, the combo produces 201.3 FPS, which falls to 124.7 FPS at 1440p, and then to 64.9 FPS at 4K. This represents a 67.8% reduction in frame rate from 1080p to 4K at High settings. The scaling is even more dramatic on the Low preset, where 366.2 FPS at 1080p drops to 230.3 FPS at 1440p and then to 123.2 FPS at 4K — a 66.4% decrease overall. These large percentage drops indicate that the RTX 5070 is the limiting factor as resolution increases, with the i5-12400 providing sufficient throughput at lower resolutions.

The Medium preset tells a similar story: 258 FPS at 1080p, 161.2 FPS at 1440p, and 86.4 FPS at 4K. The scaling factor between 1080p and 4K is roughly 2.99x, which is close to the theoretical pixel count difference of 4x, suggesting that the GPU's raw fill rate and bandwidth are the primary constraints at higher resolutions. The Ultra preset shows the most severe drop, falling from 130.7 FPS at 1080p to 85.6 FPS at 1440p and then to 46.3 FPS at 4K. This 64.6% decline from 1080p to 4K indicates that the combination struggles to maintain playable frame rates at maximum quality settings in 4K.

GPU Role

The RTX 5070's specifications are central to understanding these results. With a 12 GB GDDR7 memory buffer and 672.0 GB/s of bandwidth, the GPU has ample resources for Fortnite's art style and geometry. The base clock of 2325 MHz and boost clock of 2512 MHz, combined with 6144 shading units, provide the compute throughput necessary for high frame rates. The pixel rate of 201.0 GPixel/s and texture rate of 482.3 GTexel/s directly influence how quickly the GPU can fill the screen with rendered frames, which becomes increasingly important as resolution scales.

The benchmark data shows that the GPU's performance is not fully utilized at lower resolutions. At 1080p Low, the 366.2 FPS result suggests that the i5-12400's 6 cores and 12 threads, with a boost clock of 4.40 GHz, are likely the bottleneck. The CPU's single-thread performance, evidenced by its 3DMark single-thread score of 910, limits the maximum frame rate achievable in less GPU-intensive scenarios. Conversely, at 4K Ultra, the 46.3 FPS result indicates that the GPU's memory bandwidth and ROPS (80) are the limiting factors, as the CPU has more than enough headroom to feed the GPU.

The GPU's percentile ranking of 83 among all tested GPUs, with an average benchmark score of 41687, places it in the upper tier of graphics cards. Its nearest rival, the AMD Radeon Pro 5300, scores nearly identically at 41610, a delta of just 0.2%. This performance parity is interesting, though the RTX 5070's architecture and features such as 48 RT cores and 192 tensor cores suggest it is better suited for modern game workloads.

How This Combo Ranks

Within the benchmark database, this Intel Core i5-12400 + RTX 5070 combination ranks 292 out of 1564 tested combos for Fortnite. This places it in the top 18.7% of all combinations, which is a strong result for a mid-range CPU paired with a high-end GPU. The ranking reflects the balance between the i5-12400's processing power and the RTX 5070's graphics capabilities, though the CPU's percentile of 77 versus the GPU's percentile of 83 indicates a slight imbalance favoring the GPU.

The CPU's nearest rivals in synthetic benchmarks provide context for its Fortnite performance. The Intel Core i7-9700 scores 19831, just 0.1% below the i5-12400's 19850 average, while the Intel Core i7-8700 scores 19894, 0.2% higher. These negligible deltas suggest that in CPU-bound scenarios, the i5-12400 performs nearly identically to these older i7 parts. The AMD Ryzen Threadripper PRO 5995WX scores 19928, only 0.4% higher, which is remarkable given its workstation positioning. The Intel Core i5-11600K rounds out the rivals with 19771, 0.4% below.

The GPU's rivals show a similar pattern of near-parity. The AMD Radeon Pro 5300 is 0.2% ahead, the NVIDIA Tesla M40 is 0.5% behind, the RTX 3090 is 0.6% ahead, and the AMD Radeon Pro 580X is 0.7% behind. These small deltas mean that in GPU-bound scenarios, the RTX 5070's performance is effectively equivalent to an RTX 3090, which is a significant achievement for a newer generation card.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and desired frame rate. At 1080p, all settings presets deliver playable frame rates, with even the Ultra preset reaching 130.7 FPS. For competitive play, the Low preset at 1080p offers the highest frame rate at 366.2 FPS, which is ideal for maximizing responsiveness in a battle royale context. The Medium preset at 258 FPS provides a better balance between visual quality and performance, while the High preset at 201.3 FPS still exceeds the refresh rate of most 144Hz monitors.

At 1440p, the Low preset maintains a high 230.3 FPS, making it suitable for high-refresh-rate displays. The Medium preset at 161.2 FPS is the sweet spot for most users, offering solid visual fidelity while staying above 144 FPS. The High preset at 124.7 FPS is still playable but may not fully saturate a 144Hz panel. The Ultra preset at 85.6 FPS is the weakest option, falling below the 100 FPS threshold that many players consider smooth.

At 4K, only the Low preset at 123.2 FPS and Medium preset at 86.4 FPS provide acceptable frame rates for most players. The High preset at 64.9 FPS is borderline for a competitive game, while the Ultra preset at 46.3 FPS is not recommended for gameplay. For 4K gaming, the Low preset is the only option that comfortably exceeds 120 FPS, making it the recommended choice for players who prioritize frame rate over visual detail.
