Fortnite

The Intel Core i3-12100F paired with the NVIDIA GeForce RTX 4070 presents a striking asymmetry in Fortnite: a 4-core, 8-thread CPU from the Alder Lake generation driving a high-end Ada Lovelace GPU with 12 GB of GDDR6X memory. Benchmark results across three resolutions and four settings presets reveal how this combination behaves, where the bottlenecks sit, and what the measured frame rates imply for players. The data shows a system that can deliver very high FPS at 1080p, but the scaling curve from 1080p to 4K exposes the limits of the processor and the strengths of the graphics card.

Resolution Scaling

Moving from 1920x1080 to 2560x1440 and then to 3840x2160 produces a predictable but uneven drop in average FPS across all settings. At Low settings, the average frame rate falls from 338 FPS at 1080p to 215 FPS at 1440p, a reduction of 123 FPS, then to 113 FPS at 4K, another 102 FPS lower. The percentage decline from 1080p to 4K at Low settings is roughly 66%, indicating that the GPU is becoming the primary constraint as pixel count rises. At Medium settings, the pattern is similar: 238 FPS at 1080p, 151 FPS at 1440p, and 80 FPS at 4K, with the 4K figure representing about 34% of the 1080p performance. This sharp drop at 4K suggests that the RTX 4070’s 12 GB memory and 504.2 GB/s bandwidth are being taxed heavily, but the 4-core CPU may also struggle to feed the GPU at higher resolutions.

The High preset tells a more telling story. At 1080p, the average is 184 FPS; at 1440p, it drops to 117 FPS; at 4K, it falls to 62 FPS. The gap between 1080p and 1440p is 67 FPS, while the gap between 1440p and 4K is 55 FPS, which is a more gradual decline than at Low settings. This indicates that at High settings, the workload is balanced between CPU and GPU, but the CPU’s 4 cores and 8 threads become a limiting factor at 1080p, where frame rates are high enough to expose per-core limitations. The Ultra preset shows the lowest performance overall: 122 FPS at 1080p, 77 FPS at 1440p, and 41 FPS at 4K. The 4K Ultra result of 41 FPS is barely playable, and the scaling from 1080p to 4K is a 66% reduction, similar to Low settings, suggesting that the GPU is the dominant bottleneck at Ultra.

The data implies that at 1080p, the CPU is the limiting component for all presets except Ultra, where the GPU’s ray tracing and shading load becomes more significant. At 4K, the GPU is clearly the bottleneck across all settings, as the RTX 4070’s 29.15 TFLOPS of FP32 performance and 158.4 GPixel/s pixel rate are pushed to their limits. The 4K Medium result includes a min FPS of 68 and max FPS of 92, providing a range that shows frame-time variance under load. The 1440p Medium range (129 min, 174 max) and 1080p Medium range (202 min, 274 max) similarly show that variance narrows as resolution drops, which points to the CPU handling the lower-resolution frame pacing better.

How This Combo Ranks

The combination of the Intel Core i3-12100F and NVIDIA GeForce RTX 4070 ranks 864th out of 3700 tested combos in Fortnite, placing it in the top 23% of all configurations. This rank is notable because the CPU itself sits in the 68th percentile against all CPUs, while the GPU is in the 81st percentile against all GPUs. The combo rank is lower than both individual percentiles would suggest, which indicates that the CPU is holding the GPU back in this specific game. The CPU’s avg benchmark score of 13494 is nearly identical to its nearest rival, the Intel Core 3 N355, which scores 13492 with a deltaPct of 0. The i5-9500 scores 13452, just 0.3% lower, while the Core 5 120UL scores 13594, 0.7% higher, and the i7-1250U scores 13351, 1.1% lower. These tiny deltas show that the i3-12100F is closely matched with mid-range processors from previous generations, but none of these rivals offer the same boost clock of 4.30 GHz or the 4 cores and 8 threads that Fortnite can utilize.

The GPU’s nearest rivals paint a different picture. The RTX 4070 scores 37648 on average, with the NVIDIA Tesla P4 at 37628 (0.1% higher), the AMD Radeon RX Vega 56 at 37507 (0.4% higher), the RTX 4080 Mobile at 38135 (1.3% lower), and the AMD Radeon PRO W6400 at 37157 (1.3% lower). These deltas are all within 1.3%, meaning the RTX 4070 is statistically tied with these GPUs in synthetic benchmarks, yet in Fortnite, the combo rank of 864 suggests that the CPU limits the GPU’s potential. The rank implies that many other combos with stronger CPUs and similar or weaker GPUs achieve better Fortnite performance, which is a direct consequence of the i3-12100F’s 4-core limit.

A: The combo ranks 864th out of 3700, while the CPU sits in the 68th percentile and the GPU in the 81st percentile. The combo rank is lower than both individual percentiles, indicating that the CPU’s 4-core configuration limits the GPU’s ability to perform at its full potential in Fortnite.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are 338 for Low, 238 for Medium, 184 for High, and 122 for Ultra. The Medium preset includes a min FPS of 202 and max FPS of 274, which are the only range values recorded at this resolution. The spread from Low to Ultra is 216 FPS, with Low outperforming Ultra by a factor of 2.8. This wide gap demonstrates how heavily the Ultra preset’s effects, likely including ray tracing and advanced shadows, tax the GPU. The 1080p results show that the i3-12100F can sustain frame rates above 120 FPS even at Ultra, but the CPU’s 4 cores and 8 threads may cause stutters in crowded battle royale scenarios, though the data does not include min FPS values for most presets to confirm this.

At 2560x1440, the averages are 215 FPS for Low, 151 FPS for Medium, 117 FPS for High, and 77 FPS for Ultra. The Medium preset again provides a range with min 129 and max 174 FPS. The transition from 1080p to 1440p reduces FPS by 36% at Low, 37% at Medium, 36% at High, and 37% at Ultra, showing a consistent scaling factor across all settings. This consistency suggests that the GPU is handling the increased pixel count in a linear fashion, while the CPU’s role remains constant. The 1440p High result of 117 FPS is notably above 60 FPS, making this resolution viable for competitive play, but the 4K result of 62 FPS at High is just barely at the playable threshold.

At 3840x2160, the averages are 113 FPS for Low, 80 FPS for Medium, 62 FPS for High, and 41 FPS for Ultra. The Medium preset’s range is 68 to 92 FPS, which is the only range at 4K. The drop from 1440p to 4K is 47% at Low, 47% at Medium, 47% at High, and 47% at Ultra, which is a uniform reduction. This uniformity indicates that the GPU’s memory bandwidth of 504.2 GB/s and 12 GB capacity are the limiting factors at 4K, as the CPU has less impact at higher resolutions. The 4K Ultra result of 41 FPS is below 60 FPS, suggesting that this combo cannot maintain smooth gameplay at maximum settings in 4K, while Low and Medium presets remain playable.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with a 5 nm process and 35,800 million transistors on a 294 mm² die. Its base clock is 1920 MHz, boosting to 2475 MHz, and it features 5888 shading units, 184 texture mapping units, and 64 raster output pipelines. The GPU’s memory subsystem consists of 12 GB of GDDR6X on a 192-bit bus, yielding a bandwidth of 504.2 GB/s and a memory clock of 1313 MHz (21 Gbps effective). In Fortnite, the GPU’s role becomes more pronounced at higher resolutions and presets. The 4K results, where FPS drops to 41 at Ultra, demonstrate that the GPU’s 29.15 TFLOPS of FP32 performance is insufficient for maxed-out settings at 2160p. The pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s are the theoretical limits that the measured FPS reflects.

The GPU’s 46 ray tracing cores and 184 tensor cores support DirectX 12 Ultimate, which Fortnite can leverage, but the data does not specify whether ray tracing is enabled in the Ultra preset. The 4K Medium range of 68 to 92 FPS shows that the GPU can handle moderate settings at high resolution, but the 12 GB memory may be a limiting factor for textures at Ultra, as the 41 FPS result suggests memory pressure. The GPU’s avg benchmark score of 37648 places it in the 81st percentile, but in Fortnite, the measured FPS at 1080p Low (338 FPS) shows that the GPU is rarely the bottleneck at lower resolutions. The GPU’s 200 W TDP and dual-slot design indicate a power-hungry card, but the data does not include thermal or power measurements in-game.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor from the Alder Lake-S architecture, manufactured on Intel’s 10 nm process. It has a base clock of 3.30 GHz and a boost clock of 4.30 GHz, with a 58 W TDP. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 12 MB of shared L3 cache. In Fortnite, the CPU’s role is most evident at 1080p, where frame rates exceed 184 FPS at High settings. The CPU’s single-thread performance, as measured by a passmark single-thread score of 3444 and a geekbench single-core score of 1932, is strong for a 4-core part, but the limited core count means that the GPU cannot always be fed with enough draw calls in a fast-paced battle royale. The CPU’s cinebench r23 multicore score of 11860 and 3dmark 16-thread score of 4051 show that multithreaded performance is adequate, but not exceptional.

The CPU’s nearest rivals, such as the Intel Core i5-9500 with an avg score of 13452 (0.3% lower), indicate that the i3-12100F is competitive with older 6-core parts in synthetic tests. However, in Fortnite, the combo rank of 864 suggests that the 4-core limitation becomes a factor when the GPU is capable of very high FPS. The boost clock of 4.30 GHz is critical for maintaining high average FPS at 1080p, but the lack of additional cores means that background tasks or complex scenes with many players could cause drops, though the data does not provide min FPS for most presets to confirm this. The CPU supports DDR4 and DDR5 memory, but the data does not specify which was used in testing, which could affect performance.

Settings Recommendations

Based on the measured FPS values, the best experience for this combo depends on the target resolution. At 1920x1080, the Medium preset delivers 238 FPS with a range of 202 to 274 FPS, which is more than enough for high-refresh-rate monitors and provides better visuals than Low. The High preset at 184 FPS is also viable, but the jump from Medium to High costs 54 FPS, which is a significant trade-off for visual fidelity. Low settings at 338 FPS are only recommended for competitive players who prioritize maximum frame rate over visuals, as the difference between Low and Medium is 100 FPS, but Medium offers a more stable experience with a narrower range.

At 2560x1440, the Medium preset stands out with 151 FPS and a range of 129 to 174 FPS, making it the best choice for a balance of quality and smoothness. High settings at 117 FPS are still above 60 FPS, but the 34 FPS drop from Medium to High may be noticeable on 144 Hz displays. Low settings at 215 FPS are excessive for most 1440p monitors, which typically cap at 144 Hz or 165 Hz, so Medium is the recommended preset. Ultra at 77 FPS is playable, but the trade-off in visual effects may not justify the 74 FPS loss from Medium.

At 3840x2160, the recommended preset is Medium, with an average of 80 FPS and a range of 68 to 92 FPS. This is the only 4K preset that consistently exceeds 60 FPS, as High averages 62 FPS (which could dip below 60 in intense scenes), and Ultra averages 41 FPS, which is not smooth. Low settings at 113 FPS are an option for 4K gamers who want high frame rates, but the visual quality is significantly reduced. The data implies that this combo is best suited for 1440p gaming, where Medium or High presets offer a strong experience, and that 4K should be reserved for Medium settings or lower.
