Microsoft Flight Simulator

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

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor built on the Zen 4 architecture (Raphael) using a 5 nm process. It runs on the AMD Socket AM5 platform with a base clock of 4.70 GHz and a boost clock of 5.60 GHz. This CPU sits in the 91st percentile versus all tested processors, with an average benchmark score of 53,288. Its nearest rivals include the AMD EPYC 7313P (0.2% ahead), the Intel Xeon Phi 7290 (0.3% behind), the Intel Xeon 634 (0.6% ahead), and the Intel Core i7-14700F (0.6% behind). The performance deltas here are tiny, meaning the 7900X is trading blows with server-class and high-end desktop parts.

For Microsoft Flight Simulator, the CPU's job is substantial. The simulator is known for heavy single-threaded simulation logic, but the 7900X also brings 24 threads to handle scenery loading, AI traffic, and physics calculations. The single-thread benchmark scores are telling: 3DMark single-thread at 1,093, Cinebench R23 single-core at 2,016.5, and Geekbench single-core at 2,617. These numbers indicate strong per-core performance, which matters because flight simulators often bottleneck on a single main thread even when other cores sit idle. The multi-threaded results are equally robust: Cinebench R23 multi-core at 29,300, Geekbench multi-core at 19,267, and PassMark multi-thread at 51,406. This combination of strong single-thread and multi-thread scores means the CPU can handle both the simulation thread and background tasks without dragging down the frame rate.

The 7900X has 64 MB of shared L3 cache, which is significant for a flight simulator that streams terrain and airport data. It also supports DDR5 memory with a dual-channel bus and 83.2 GB/s memory bandwidth. In a game like Microsoft Flight Simulator, the memory subsystem can become a factor when the CPU is fetching large amounts of world data. The 170 W TDP and unlocked multiplier suggest this is a desktop enthusiast part, not a power-constrained mobile chip. The CPU's position relative to its nearest rivals — within 0.6% in either direction — shows that in synthetic benchmarks, the 7900X is essentially at parity with the EPYC 7313P and the Core i7-14700F. However, the actual game results will depend on how well the simulator uses those cores and threads.

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

The Intel Arc B570 is a Battlemage-generation GPU (Arc 5 series) built on a 5 nm process from TSMC. It features 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The GPU clocks are set at 2500 MHz base and 2500 MHz boost, with memory running at 2375 MHz (19 Gbps effective). The B570 has 2,304 shading units, 144 texture mapping units, and 80 raster output units, along with 18 ray tracing cores. Its compute performance is rated at 11.52 TFLOPS FP32 and 23.04 TFLOPS FP16 (2:1 ratio). The pixel rate is 200.0 GPixel/s and the texture rate is 360.0 GTexel/s.

This GPU sits in the 65th percentile versus all tested GPUs, with an average benchmark score of 20,556. Its nearest rivals are the NVIDIA GeForce RTX 3070 Mobile (0.1% ahead), the Intel Arc A750 (0.1% behind), the NVIDIA Quadro M4000M (0.4% ahead), and the AMD Radeon R9 M390X (0.5% behind). The deltaPct values show that the B570 is essentially matching a mobile RTX 3070 and the previous-generation Arc A750 in aggregate benchmarks. The 10 GB VRAM capacity is a key attribute for Microsoft Flight Simulator, which loads large texture sets for terrain, aircraft, and cities. At higher resolutions, VRAM pressure increases, and 10 GB can be a limiting factor if the simulator tries to load ultra-quality textures.

The 160-bit memory bus and 380 GB/s bandwidth are moderate — not top-tier, but sufficient for 1080p and 1440p gaming. The 2500 MHz boost clock is consistent, meaning the GPU won't throttle unpredictably under sustained load. The B570 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, which is relevant because Microsoft Flight Simulator can use DX12 and Vulkan paths depending on settings. The GPU's transistor count of 19,600 million on a 272 mm² die gives it a density of 72.1M per mm², indicating a modern, dense design. The 150 W TDP and single 8-pin power connector mean it won't stress a power supply beyond 450 W suggested rating.

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 resolution scaling. At 1920x1080 with Low settings, the combo achieves 86 FPS average. Moving to 2560x1440 at Low, that drops to 69 FPS, and at 3840x2160 at Low, it falls to 51 FPS. The drop from 1080p to 1440p is 17 FPS (about 20% reduction), and from 1440p to 4K is another 18 FPS (about 26% reduction). This scaling suggests that at Low settings, the GPU is more heavily involved, but the CPU still has headroom to push higher frame rates at lower resolutions.

At High settings, the pattern shifts. 1080p High yields 50 FPS, 1440p High drops to 41 FPS, and 4K High falls to 30 FPS. The drop from 1080p to 1440p is 9 FPS (18% reduction), and from 1440p to 4K is 11 FPS (27% reduction). At Ultra settings, 1080p gives 48 FPS, 1440p gives 39 FPS, and 4K gives 28 FPS. The scaling is similar: 9 FPS drop to 1440p, then 11 FPS drop to 4K. The consistent percentage reductions across settings indicate that the GPU is the limiting factor at higher resolutions — the CPU isn't the bottleneck because the frame rates scale proportionally with resolution.

However, looking at the Low settings specifically, the 1080p result of 86 FPS compared to 4K at 51 FPS shows a 35 FPS drop (41% reduction). This is a larger absolute drop than at High or Ultra, which suggests that when the GPU work is light (Low settings), the CPU can push more frames at lower resolutions, but the GPU still becomes the constraint at 4K. The data indicates a balanced system where neither component is severely underpowered, but at 4K Ultra, the GPU is clearly the limiting factor — 28 FPS is below playable thresholds for most users. At 1080p Low, the CPU is doing heavy lifting, and at 4K Ultra, the GPU is overwhelmed.

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

1920x1080 (1080p):

• Low: 86 FPS average
• Medium: 67 FPS average (min 57, max 77)
• High: 50 FPS average
• Ultra: 48 FPS average

2560x1440 (1440p):

• Low: 69 FPS average
• Medium: 54 FPS average (min 46, max 62)
• High: 41 FPS average
• Ultra: 39 FPS average

3840x2160 (4K):

• Low: 51 FPS average
• Medium: 40 FPS average (min 34, max 46)
• High: 30 FPS average
• Ultra: 28 FPS average

The 1080p results show a wide spread between Low and Ultra: 86 FPS down to 48 FPS, a 38 FPS difference. This indicates that the GPU has to work progressively harder as settings rise, but the CPU can keep up at all settings. The Medium preset at 1080p has a min FPS of 57 and max of 77, showing some frame pacing variability but no severe stutters. The 1440p results compress the range: 69 FPS at Low down to 39 FPS at Ultra, a 30 FPS difference. The Medium preset at 1440p shows min 46 and max 62, which is a narrower band than at 1080p. At 4K, the range narrows further: 51 FPS at Low down to 28 FPS at Ultra, a 23 FPS difference. The Medium preset at 4K has min 34 and max 46, indicating that frame times become more consistent as resolution increases, but average FPS drops.

The interpretation is straightforward. At 1080p, the system is CPU-bound at Low settings (86 FPS shows the CPU's ceiling), but GPU-bound at Ultra (48 FPS). At 4K, the system is GPU-bound across all settings — even at Low, the GPU can only manage 51 FPS. The medium presets at each resolution provide the most stable frame pacing (narrow min-max ranges), suggesting that Medium is the sweet spot for consistent performance. For a flight simulator, where smoothness matters more than raw FPS, the Medium preset at 1440p (54 FPS average) or 1080p (67 FPS average) would be the recommended settings. The 4K Ultra result of 28 FPS is effectively unplayable for most flight sim enthusiasts.

How This Combo Ranks — use comboRankInGame vs other tested combos

This specific combination of AMD Ryzen 9 7900X and Intel Arc B570 ranks 2,406 out of 2,996 tested combos in Microsoft Flight Simulator. That places it in the bottom 20% of all tested configurations — specifically, it's better than 590 combos but worse than 2,405 others. This rank is notably low for a CPU that sits in the 91st percentile and a GPU in the 65th percentile. The discrepancy highlights that raw component benchmarks don't always translate to game-specific performance.

The combo rank of 2,406/2,996 means that the vast majority of tested systems outperform this pairing in Microsoft Flight Simulator. This is likely because the game is extremely demanding on both CPU and GPU, and the Arc B570's 10 GB VRAM and 160-bit bus are modest for a game that can consume large amounts of memory at high settings. The CPU's 91st percentile ranking suggests it's not the primary drag, but the GPU's 65th percentile ranking is below average for a system expected to run a flight simulator at decent settings. In practical terms, this combo is suited for 1080p Medium or Low settings, but it won't excel at 1440p High or 4K Ultra.

Looking at the measured FPS, the combo achieves 30 FPS at 4K High and 28 FPS at 4K Ultra — both below the 30 FPS threshold often considered the minimum for playability. At 1440p High (41 FPS) and 1080p High (50 FPS), the results are playable but not smooth by modern standards. The rank of 2,406 suggests that many other CPUs and GPUs in the database deliver better frame rates, likely including systems with higher-end GPUs that pair better with the 7900X. For reference, the 7900X's nearest CPU rivals (EPYC 7313P, Xeon 634, etc.) are server parts unlikely to be paired with a mid-range GPU like the B570. The GPU's nearest rivals include the RTX 3070 Mobile and Arc A750, which are comparable in synthetic tests but may perform differently in this game.
