Microsoft Flight Simulator

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

The AMD Ryzen 5 7600 brings six cores and twelve threads to Microsoft Flight Simulator, running at a base clock of 3.80 GHz and boosting to 5.10 GHz. This is a Zen 4 Raphael part on the AMD Socket AM5 platform, built on a 5 nm process at TSMC. The 6,570 million transistors are arranged in a 71 mm² die, and the cache layout provides 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3.

For a flight simulator, the CPU workload is substantial. The game engine has to process terrain data, weather simulation, and aircraft systems continuously, and it does not scale perfectly across many threads. The Ryzen 5 7600's single-thread performance is its strong suit here. Its 3DMark single-thread score of 999 places it well above the 83rd percentile of all CPUs tested, meaning it will handle the game's primary simulation thread competently.

Multi-threaded results are equally respectable. The Cinebench R23 multi-core score of 22,992 and the 3DMark max-threads score of 6,503 show that the 12 threads are not a bottleneck when the game does spread work across cores. The average benchmark score of 26,617 places this CPU in a tight cluster with its nearest rivals: the AMD Ryzen 7 5800X3D scores 26,574 (0.2% higher), the Intel Core i9-12900HK scores 26,672 (0.2% lower), and the AMD EPYC 8024P scores 26,555 (0.2% higher). The Intel Core i9-11900K sits 0.3% ahead at 26,546. These deltas are within noise, meaning the 7600 is effectively tied with these parts in overall compute.

In practical terms for Flight Simulator, the CPU's job is to feed the GPU with draw calls and manage the simulation state. The 65 W TDP and DDR5 memory support with 83.2 GB/s bandwidth give the CPU enough headroom to maintain consistent frame pacing. The data shows that at 1080p Low settings, the combo reaches 95.1 FPS, which indicates the CPU is not holding back the GPU at lower resolutions where the graphics card has less work to do.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B580 is a Battlemage-generation GPU with the BMG-G21 chip, built on a 5 nm TSMC process with 19,600 million transistors on a 272 mm² die. It operates with a base and boost clock of 2670 MHz, and its memory runs at 2375 MHz (19 Gbps effective) across a 192-bit bus. The 12 GB of GDDR6 VRAM provides 456.0 GB/s of bandwidth, which is a meaningful amount for a flight simulator that loads large texture sets and terrain data.

The GPU's compute resources include 2,560 shading units, 160 TMUs, and 80 ROPs, with 20 ray tracing cores. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s indicate solid fill rate capabilities. The FP32 performance of 13.67 TFLOPS places this card in the mid-range segment, and its 66th percentile ranking among all GPUs confirms that positioning.

Looking at the nearest rivals, the Arc B580's average benchmark score of 23,021 is nearly identical to the AMD Radeon 760M (22,999, 0.1% higher) and the NVIDIA P106-100 (22,950, 0.3% higher). The NVIDIA GeForce RTX 4060 scores 23,181, which is 0.7% higher, while the RTX 4060 Mobile trails by 1.3% with a score of 22,729. This GPU sits in a competitive band where small percentage differences translate to a few frames.

In Flight Simulator specifically, the GPU's VRAM capacity becomes important at higher settings. The 12 GB frame buffer is sufficient for Ultra presets at 1080p and 1440p, and the measured data shows the card handling these loads without catastrophic drops. The 456.0 GB/s bandwidth helps when the sim streams in new scenery tiles as you fly, which is a memory-bandwidth-intensive workload.

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

The measured FPS data reveals a clear pattern of GPU-bound behavior as resolution increases. At Low settings, the frame rate drops from 95.1 FPS at 1080p to 75.2 FPS at 1440p and then to 54.6 FPS at 4K. That is a 20.9% drop from 1080p to 1440p and a further 27.4% drop from 1440p to 4K. This steep scaling indicates the GPU is the limiting factor at higher resolutions, even on the least demanding preset.

At Medium settings, the progression is 76.4 FPS at 1080p, 61.6 FPS at 1440p, and 41.6 FPS at 4K. The drop from 1080p to 1440p is 19.4%, and from 1440p to 4K it is 32.5%. The larger drop at 4K suggests that the GPU's memory bandwidth and compute are being saturated by the increased pixel count and texture detail.

High settings show a similar trend: 56.1 FPS at 1080p, 46.2 FPS at 1440p, and 32.7 FPS at 4K. The percentage drops are 17.6% and 29.2%, respectively. Ultra settings produce 51.6 FPS at 1080p, 41.4 FPS at 1440p, and 33.3 FPS at 4K. Here, the drop from 1080p to 1440p is 19.8%, but the drop from 1440p to 4K is only 19.6%, which is the smallest relative decline across all settings.

The fact that the CPU can push 95.1 FPS at 1080p Low but the GPU only manages 54.6 FPS at 4K Low points to the Arc B580 being the bottleneck at higher resolutions. The Ryzen 5 7600 has enough headroom to drive higher frame rates if the GPU could keep up. The shrinking gap between High and Ultra at 4K (32.7 vs 33.3 FPS) suggests that the GPU is hitting a hard performance ceiling regardless of how much additional visual detail is enabled.

How This Combo Ranks — use comboRankInGame vs other tested combos

This combination of the AMD Ryzen 5 7600 and Intel Arc B580 ranks 1,421 out of 1,795 tested combos in Microsoft Flight Simulator. That places it in the lower-middle portion of the field, which is a meaningful signal. The CPU alone sits at the 83rd percentile among all CPUs, and the GPU at the 66th percentile among all GPUs, but the combined result is not the sum of those parts.

The rank position indicates that while each component is competent individually, the pairing does not boost to a top-tier experience in this specific game. Flight Simulator is known to be heavily single-thread dependent on the CPU side and VRAM-hungry on the GPU side, and this combo's 12 GB of VRAM and strong single-thread CPU score (3DMark single-thread 999) are not enough to break into the upper quartile of test results.

Compared to the nearest rival combos that would feature the Ryzen 7 5800X3D or the RTX 4060, this pairing would likely trail in scenarios where the extra L3 cache of the 5800X3D or the superior rasterization of the RTX 4060 matters. The data shows the GPU is within 0.7% of the RTX 4060 in average benchmark score, but the 5800X3D's 0.2% advantage over the 7600 in CPU benchmarks suggests the CPU side is not the differentiator.

The practical takeaway is that this combo is a serviceable mid-range pairing for Flight Simulator, but it will not deliver high-refresh-rate experiences at 4K. The rank of 1,421 out of 1,795 means roughly 79% of tested combos perform better in this game, which aligns with the measured FPS numbers showing sub-60 FPS at 1440p High and 4K Medium.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured data points to Medium settings at 1440p as the sweet spot for this combo. At 2560x1440 Medium, the average FPS is 61.6, which clears the 60 FPS threshold that most users consider acceptable for a smooth flight sim experience. The 1080p Medium result of 76.4 FPS is smoother, but the visual fidelity gain from 1080p to 1440p at Medium is substantial for terrain readability.

If the user prioritizes frame rate over visual detail, 1080p Low at 95.1 FPS is the highest measured result and offers the most headroom for complex scenes with dense clouds or heavy airports. The 75.2 FPS at 1440p Low is also viable and provides a good balance of resolution and smoothness.

At 4K, the options are more constrained. Low settings produce 54.6 FPS, which is near playable but may dip in demanding scenarios. Medium at 4K drops to 41.6 FPS, and High to 32.7 FPS. Ultra at 4K yields 33.3 FPS, which is barely distinguishable from High in this measurement. The data suggests that 4K gaming with this combo requires accepting Low settings for a playable frame rate, and even then, the margin is thin.

For most users, the recommendation is 1440p Medium as the default. It provides 61.6 FPS, which is smooth enough for flight simulation where the camera moves slowly relative to other genres. Users who want to push visual quality can try 1440p High at 46.2 FPS, but the jump from Medium to High costs about 15 FPS, which is a significant trade-off for incremental visual gains. The Ultra preset at 1440p (41.4 FPS) offers even less value per frame lost.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the combo produces its best results. Low settings yield an average of 95.1 FPS, which is the highest measured frame rate across all configurations. Medium settings drop to 76.4 FPS, a 19.7% reduction. High settings further reduce to 56.1 FPS, a 26.6% drop from Medium. Ultra settings produce 51.6 FPS, which is 8.0% below High and 45.7% below Low. This resolution shows the clearest separation between presets, indicating the GPU has enough headroom to differentiate between quality levels.

At 2560x1440, the frame rates compress somewhat. Low settings average 75.2 FPS, which is 20.9% lower than the 1080p Low result. Medium settings average 61.6 FPS, an 18.1% reduction from 1080p Medium. High settings produce 46.2 FPS, a 17.6% drop from 1080p High. Ultra settings yield 41.4 FPS, which is 19.8% lower than 1080p Ultra. The gaps between presets narrow here, with Low to Medium showing a 18.1% difference and Medium to High a 25.0% difference.

At 3840x2160, the GPU is clearly struggling. Low settings average 54.6 FPS, which is 27.4% below the 1440p Low result. Medium settings drop to 41.6 FPS, a 32.5% reduction from 1440p Medium. High settings produce 32.7 FPS, a 29.2% drop from 1440p High. Ultra settings average 33.3 FPS, which is 19.6% below 1440p Ultra. Notably, the difference between High and Ultra at 4K is only 0.6 FPS, suggesting the GPU is saturated and additional graphical features have minimal impact on performance.

The full picture shows that this combo is best utilized at 1080p or 1440p with Medium or Low settings. The 4K results, while measurable, do not provide a consistently smooth experience at any preset above Low. The 12 GB VRAM and 456.0 GB/s bandwidth are adequate for 1080p and 1440p Ultra, but the GPU's raw compute power of 13.67 TFLOPS is the limiting factor at 4K.
