CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-12600KF is a 10-core, 16-thread desktop processor built on Intel's Alder Lake architecture and the 10 nm process node. It operates with a base clock of 3.70 GHz and a boost clock of 4.90 GHz, drawing up to 125 W TDP. The chip features a hybrid design, though the fact pack does not specify the exact P-core/E-core split; what is clear is that its cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and a shared 20 MB L3 cache. Memory support spans both DDR4 and DDR5 in dual-channel mode, and the CPU provides 20 PCIe Gen 4 lanes.

In synthetic benchmarks, the i5-12600KF posts a Cinebench R23 multi-core score of 23391 and a single-core score of 3302. Its 3DMark results show scaling from a 2-thread score of 1995 up to a max-thread score of 7952, with a single-thread score of 1016. The CPU's average benchmark score is 27799, placing it in the 79th percentile among all CPUs. Compared to its nearest rivals, the i5-12600KF is essentially neck-and-neck with the Intel Core i9-10900K (deltaPct -0.3), the AMD Ryzen 5 8500GE (deltaPct +0.3), the AMD Ryzen 7 6800U (deltaPct -0.3), and the AMD Ryzen 7 5800X3D (deltaPct -0.3). These tiny deltas mean that for CPU-bound tasks, the i5-12600KF trades blows with these competing parts within a fraction of a percent.

For Microsoft Flight Simulator, the CPU's role is primarily about maintaining a stable frame pipeline, especially at lower resolutions where the GPU has spare capacity. The measured FPS data shows that at 1080p Low, the combo achieves 164 FPS, while at 1080p Ultra, it drops to 91 FPS. This 73 FPS gap across settings indicates that the CPU is not the limiting factor at the low end; rather, the GPU load from higher settings becomes the bottleneck. The i5-12600KF's strong single-thread performance (Geekbench single-core 2157, Passmark single-thread 3925) helps with the sim's physics and AI calculations, which are often latency-sensitive. The multi-threaded headroom (Cinebench R23 multi-core 23391) ensures that background tasks and the sim's terrain streaming do not cause stutters, as evidenced by the 1080p Medium min FPS of 108 FPS, which is well above playable thresholds.

These deltas show that the RTX 3080 Ti sits in a competitive band, with the RTX 5070 being 2% ahead and the Radeon Pro 5300 being 0.8% ahead.

For Microsoft Flight Simulator, the GPU's 12 GB VRAM is crucial at high resolutions and detail levels. The measured data shows that at 4K Ultra, the combo averages 54 FPS, while at 4K Low it reaches 97 FPS. This 43 FPS spread across 4K settings demonstrates the GPU's workload sensitivity. The high bandwidth of 912.4 GB/s helps with texture streaming, which is a common bottleneck in flight sims that load large photogrammetry and terrain data. The RTX 3080 Ti's 80 RT cores and 320 tensor cores are not specifically utilized by this game's measured presets, but the raw rasterization performance from 10,240 shading units is what drives FPS. At 1440p High, the combo hits 77 FPS, and at 1440p Ultra, it manages 74 FPS, indicating that the GPU can maintain playable frame rates even at demanding settings.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear scaling pattern across resolutions. At 1080p, the combo delivers 164 FPS on Low, 127 FPS on Medium, 96 FPS on High, and 91 FPS on Ultra. Moving to 1440p, these numbers drop to 132 FPS (Low), 103 FPS (Medium), 77 FPS (High), and 74 FPS (Ultra). At 4K, the averages fall further to 97 FPS (Low), 76 FPS (Medium), 57 FPS (High), and 54 FPS (Ultra).

The percentage drops from 1080p to 4K are steepest at lower settings: Low settings drop from 164 FPS to 97 FPS (a 41% reduction), while Ultra settings drop from 91 FPS to 54 FPS (a 41% reduction as well). Interestingly, the Medium and High settings show similar relative declines — Medium drops from 127 to 76 FPS (40% reduction), and High drops from 96 to 57 FPS (41% reduction). This uniform scaling pattern indicates that the GPU is the primary limiting component across all resolutions, as the FPS reduction is proportional to the pixel count increase (1080p has 2.07 million pixels, 1440p has 3.69 million, and 4K has 8.29 million). The GPU's rendering load scales nearly linearly with resolution, and the CPU's performance headroom (as shown by its high synthetic scores) is sufficient to feed the GPU even at 1080p Low where the GPU is less stressed.

The 1440p to 4K transition shows a further 26% average FPS drop across all settings (from 77 to 57 FPS on High, for example), which again points to GPU-bound behavior. The fact that 4K Low (97 FPS) is nearly identical to 1080p High (96 FPS) suggests that the GPU can handle the lower-detail workload at higher resolution, but the CPU remains capable of delivering high frame rates when the GPU is not saturated. This data indicates that users upgrading from lower resolutions will see consistent performance degradation, but the RTX 3080 Ti's 12 GB VRAM and 912.4 GB/s bandwidth prevent any memory-related cliff at 4K.
