Microsoft Flight Simulator

Microsoft Flight Simulator is an exceptionally demanding title, and the pairing of the Intel Core i3-12100F with the AMD Radeon RX 6700 XT produces a fascinating bottleneck profile. The combo ranks 988th out of 1795 tested combinations, placing it in the upper-middle tier of the database. Benchmark results indicate that this system is capable of delivering playable frame rates, but the performance ceiling varies dramatically depending on whether the CPU or GPU becomes the limiting factor at a given resolution and settings level.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor based on the Alder Lake architecture, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. It features a 12 MB shared L3 cache and 1.25 MB of L2 cache per core. In synthetic benchmarks, this CPU demonstrates strong single-thread capabilities with a 3dmark_single_thread score of 893 and a Geekbench single-core score of 2224, which is critical for a flight simulator that often relies on a primary simulation thread.

However, the CPU's multi-threaded performance reveals its limitations. The Cinebench R23 multicore score of 11912 and the Passmark multithread score of 14015 place it at the 72nd percentile against all CPUs. The data shows a clear scaling pattern: the 3dmark_4_threads score of 2859 jumps to 4026 for 8 threads, but the max_threads score of 4023 shows that adding more threads beyond 8 provides no benefit. This indicates that the processor's performance is effectively capped by its physical core count.

In the context of Microsoft Flight Simulator, the CPU's role is significant at lower resolutions. The measured FPS data shows that at 1080p Low settings, the system achieves 123.4 FPS, which is the highest average across all tested configurations. This suggests that at lower graphical loads, the CPU is able to feed the GPU adequately. However, the CPU's relative weakness becomes apparent when compared to its nearest rivals. The i3-12100F has an average benchmark score of 13516, which is nearly identical to the AMD Ryzen Threadripper PRO 3975WX (13534, a -0.1% delta) and the Intel Core i7-1250U (13462, a 0.4% delta). It is only 1.8% ahead of the Intel Core i7-7700K (13280). This places the i3 in a performance tier where it is competitive with older high-end parts but lacks the headroom of modern 8-core designs.

GPU Role

The AMD Radeon RX 6700 XT is built on the RDNA 2.0 architecture with a 7 nm process node and features 12 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 384.0 GB/s. The GPU operates at a base clock of 2321 MHz, a game clock of 2424 MHz, and a boost clock of 2581 MHz. With 2560 shading units, 160 TMUs, and 64 ROPs, the card delivers a theoretical FP32 performance of 13.21 TFLOPS.

The GPU's synthetic benchmark scores show it is a capable performer, sitting at the 77th percentile among all GPUs. Its average benchmark score of 33721 places it just 0.7% behind the AMD Radeon RX 6800 (33493) and 1% ahead of both the AMD Radeon HD 7950 (34050) and AMD Radeon RX 480 (34059). The GPU is also 1.3% ahead of the NVIDIA RTX A5000 (33294). These deltas are remarkably tight, indicating that the RX 6700 XT sits in a highly competitive performance band where small architectural differences dictate positioning.

In Microsoft Flight Simulator, the GPU's 12 GB VRAM buffer and high memory bandwidth are crucial for handling the dense terrain data and high-resolution textures. The data shows that the GPU becomes the primary bottleneck at higher settings and resolutions. At 4K Ultra settings, the average FPS drops to 38.9, which is the lowest measured result. This aligns with the GPU's compute capabilities, as the card struggles to maintain real-time rendering of the complex scenery at maximum quality. The GPU's DirectX 12 benchmark score of 77 and Vulkan score of 108032 from Geekbench suggest it has adequate API support, but the raw throughput is insufficient for the most demanding presets at 4K.

Resolution Scaling

The measured FPS data reveals a clear pattern of CPU and GPU bottlenecking across resolutions. At 1080p, the system shows strong performance, with Low settings achieving 123.4 FPS, Medium at 93.4 FPS, High at 70.4 FPS, and Ultra at 68.6 FPS. The relatively small gap between High and Ultra at 1080p (70.4 vs 68.6 FPS) suggests that the CPU is starting to limit performance, as the GPU has enough headroom to handle the extra graphical load without a significant frame rate penalty.

Moving to 1440p, the frame rates drop proportionally: Low settings yield 97.1 FPS, Medium 76.1 FPS, High 55.2 FPS, and Ultra 52.9 FPS. The delta between 1080p and 1440p at Low settings is a 26.3 FPS drop (from 123.4 to 97.1), which is a 21.3% reduction. This indicates that the GPU is beginning to become more relevant, but the CPU still holds some influence.

At 4K resolution, the bottleneck shifts decisively to the GPU. The frame rates are 67.8 FPS at Low, 56.3 FPS at Medium, 40.1 FPS at High, and 38.9 FPS at Ultra. The scaling from 1440p to 4K at Low settings shows a 29.3 FPS drop (from 97.1 to 67.8), a 30.2% reduction. This steep decline at the lowest settings level is a hallmark of GPU limitation, as the increased pixel count demands more from the renderer regardless of the CPU's capabilities. The data suggests that the RX 6700 XT is the limiting component at 4K, while the i3-12100F is more likely to constrain performance at 1080p.

FAQ

A: The data suggests it does not significantly impact 4K performance. At 4K Ultra, the system achieves 38.9 FPS, and at 4K High it gets 40.1 FPS, with minimal variation between these settings. This indicates the GPU is the primary bottleneck, as the CPU's workload does not change much with these settings.

Q: How does this combo rank against all tested configurations?

A: The combo ranks 988th out of 1795 tested combinations, placing it in the 55th percentile of all systems tested for this game. This indicates it performs above the median but is not in the top tier of configurations.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its highest performance ceiling. Low settings produce an average of 123.4 FPS, providing a smooth experience. Medium settings reduce the average to 93.4 FPS, still well above the 60 FPS threshold. High settings yield 70.4 FPS, and Ultra settings deliver 68.6 FPS. The narrow gap between High and Ultra (1.8 FPS) suggests that the CPU is limiting performance at this resolution, as the GPU is capable of rendering both presets at similar speeds.

At 2560x1440, the performance scales predictably. Low settings average 97.1 FPS, maintaining high fluidity. Medium settings average 76.1 FPS, which is still comfortable for most displays. High settings drop to 55.2 FPS, and Ultra settings fall to 52.9 FPS, indicating that users must accept frame rates below 60 FPS for the higher visual fidelity presets.

At 3840x2160, the GPU becomes the dominant constraint. Low settings average 67.8 FPS, which is playable but shows a significant drop from 1440p. Medium settings average 56.3 FPS, High settings average 40.1 FPS, and Ultra settings average 38.9 FPS. The minimal difference between High and Ultra at 4K (1.2 FPS) further confirms that the GPU is fully saturated, and additional settings increases do not meaningfully impact the frame rate because the renderer is already maxed out.
