# Microsoft Flight Simulator: Intel Core Ultra 7 265K + Intel Arc B570

This combo ranks 2406th out of 2996 tested configurations in Microsoft Flight Simulator, placing it in the lower third of all measured systems. The pairing of Intel's 20-core Arrow Lake processor with Intel's 10 GB Battlemage GPU produces playable results at 1080p and 1440p on medium settings, but the data shows a system that struggles to maintain smooth framerates at higher presets and resolutions. The benchmark results indicate a CPU that is far more capable than the GPU, with the graphics card becoming the primary constraint in nearly every measured scenario.

CPU Role

The Intel Core Ultra 7 265K brings substantial processing power to this flight simulator, featuring 20 cores and 20 threads running at a base clock of 3.90 GHz with a boost clock of 5.50 GHz. This Arrow Lake-S architecture chip, built on a 3 nm process from TSMC, includes a 30 MB shared L3 cache and 3 MB L2 cache per core, with 192 KB L1 cache per core. The processor supports DDR5 memory over a dual-channel bus with 102.4 GB/s bandwidth, and it includes integrated Arc Xe-LPG Graphics with 64 execution units.

In synthetic benchmarks, the CPU demonstrates strong performance. The Cinebench R23 multi-core score reaches 35850, while the single-core result hits 2020. Geekbench tests show 23085 multi-core and 2713 single-core scores. Passmark tests reveal 58594 in multithread, 4928 in single thread, and 189629 in floating point math. The processor sits at the 94th percentile among all CPUs, with an average benchmark score of 70879.

Relative to its nearest rivals, the Core Ultra 7 265K is essentially tied with the Intel Xeon 6511P, which scores 71051 (0.2% higher). It trails the Intel Xeon Platinum 8270 by 0.7% (that chip scores 71370) and leads the Intel Core i7-14700KF by 1% (70163) and the AMD Ryzen 7 9700F by 1.3% (69996). These narrow margins confirm the CPU is performing at a high level, though not at the absolute top tier.

In Microsoft Flight Simulator, the CPU's role is substantial because flight simulation involves complex physics calculations, terrain loading, and AI traffic processing. The 20-core configuration with 20 threads means no hyper-threading, but the high boost clock of 5.50 GHz helps single-threaded performance, which is critical for the simulator's main simulation loop. The benchmark data shows that at 1080p Low settings, the system achieves 86 FPS, indicating the CPU can feed the GPU adequately at lower graphical loads. However, the CPU's capability is not fully utilized in this game at higher settings, as the GPU becomes the limiting factor.

The processor's memory bandwidth of 102.4 GB/s and DDR5 support matter for a game that streams large world data. The L3 cache of 30 MB shared is reasonably sized for loading terrain tiles and aircraft models. The 94th percentile ranking among all CPUs suggests this processor is well above average, and the nearest rival comparisons confirm it is competitive with workstation-class Xeon chips and high-end consumer parts like the Core i7-14700KF.

GPU Role

The Intel Arc B570 is a Battlemage-generation GPU built on TSMC's 5 nm process, featuring the BMG-G21 chip with 19,600 million transistors on a 272 mm² die. The card operates at a fixed 2500 MHz base and boost clock, with memory running at 2375 MHz (19 Gbps effective). It comes equipped with 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The GPU packs 2304 shading units, 144 texture mapping units, and 80 raster operation units, along with 18 ray tracing cores. Compute performance is rated at 11.52 TFLOPS FP32 and 23.04 TFLOPS FP16.

In synthetic benchmarks, the Arc B570 achieves a 3DMark Steel Nomad DX12 score of 2649, Geekbench OpenCL of 83514, and Geekbench Vulkan of 96844. Passmark tests show 14195 in G3D and 7281 in GPU compute. The GPU sits at the 65th percentile among all graphics cards, with an average benchmark score of 20556.

The nearest rivals are tightly clustered. The NVIDIA GeForce RTX 3070 Mobile scores 20534 (0.1% higher), the Intel Arc A750 scores 20582 (0.1% lower), the NVIDIA Quadro M4000M scores 20480 (0.4% higher), and the AMD Radeon R9 M390X scores 20662 (0.5% lower). This places the Arc B570 in a highly competitive band, but notably these are mobile and older desktop parts, suggesting the B570 is not a high-end desktop GPU.

For Microsoft Flight Simulator, the GPU's 10 GB VRAM is a critical factor. The game loads extensive textures for terrain, aircraft, and scenery, and 10 GB can become a constraint at higher resolutions and settings. The 380 GB/s memory bandwidth is modest for 4K workloads, and the 160-bit bus width limits memory throughput. The GPU's 65th percentile ranking indicates it is above average but not exceptional, and the game's measured performance confirms this.

The fixed 2500 MHz clock means the card runs at a consistent speed, but the FP32 throughput of 11.52 TFLOPS is relatively low for modern gaming. In this flight simulator, the GPU is clearly the bottleneck in most scenarios, as evidenced by the FPS scaling from 1080p to 4K, which will be examined in the resolution scaling section.

Settings Recommendations

The measured FPS data provides clear guidance for optimal settings. At 1080p, the Medium preset delivers 67 FPS average with a minimum of 57 FPS and maximum of 77 FPS. This is the sweet spot for smooth gameplay, offering a comfortable margin above the 60 FPS threshold while maintaining visual quality. The Low preset reaches 86 FPS, but the visual compromise is substantial. High and Ultra settings at 1080p drop to 50 FPS and 48 FPS respectively, which are borderline for a flight simulator where smooth panning is essential.

At 1440p, the Medium preset again proves the best choice, averaging 54 FPS with a minimum of 46 FPS and maximum of 62 FPS. This provides playable performance, though the minimum dipping below 50 FPS may cause minor stutters in dense scenery. The Low preset at 1440p achieves 69 FPS, which is smoother but sacrifices significant visual detail. High and Ultra at 1440p fall to 41 FPS and 39 FPS, which are too low for a comfortable experience in a game that requires sustained attention to instruments and terrain.

At 4K, the picture changes dramatically. Even the Medium preset only manages 40 FPS average with a minimum of 34 FPS and maximum of 46 FPS. Low at 4K hits 51 FPS, while High drops to 30 FPS and Ultra falls to 28 FPS. None of these 4K options provide a consistently smooth experience, with even the best preset (Low) hovering barely above 50 FPS.

The data strongly supports the Medium preset at 1080p or 1440p as the best experience. At 1080p Medium, the 67 FPS average with a 57 FPS minimum ensures mostly smooth flight. At 1440p Medium, the 54 FPS average is acceptable for a slower-paced simulation, though less ideal. For users prioritizing framerate, the Low preset at 1440p (69 FPS) or 1080p (86 FPS) offers the smoothest experience, but the visual downgrade is significant. The Ultra preset is not recommended at any resolution, as it provides only 48 FPS at 1080p, 39 FPS at 1440p, and 28 FPS at 4K — all below acceptable thresholds.

How This Combo Ranks

This configuration ranks 2406th out of 2996 tested combos in Microsoft Flight Simulator, placing it in the 20th percentile of all systems measured. This is a low ranking that reflects the GPU's limitations rather than the CPU's capabilities. The Core Ultra 7 265K is a top-tier processor at the 94th percentile, while the Arc B570 sits at only the 65th percentile among GPUs. The mismatch means the system's overall performance is dragged down by the graphics card.

The combination of a high-end CPU with a mid-range GPU is common in systems where the user prioritizes CPU-heavy workloads but games at moderate settings. In this flight simulator, the GPU bottleneck is evident: at 1080p Low, the system achieves 86 FPS, but at 4K Ultra, it falls to 28 FPS — a 67% reduction that is primarily due to GPU limitations.

Compared to other tested combos, this system performs in the lower third, which is consistent with the Arc B570's modest standing among GPUs. The CPU's strong synthetic benchmarks do not translate to a high game ranking because the game is GPU-bound at most settings. Users seeking better rankings would need a more powerful GPU, but within this specific pairing, the measured data shows a system that is adequate for 1080p Medium gaming but struggles at higher resolutions.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a clear GPU-bound profile. At Medium settings, the system achieves 67 FPS at 1080p, 54 FPS at 1440p, and 40 FPS at 4K. This represents a 20% drop from 1080p to 1440p and a 40% drop from 1440p to 4K. The scaling is nearly linear with pixel count, which is characteristic of a GPU-limited scenario where the CPU has headroom to spare.

At Low settings, the scaling is similar: 86 FPS at 1080p, 69 FPS at 1440p, and 51 FPS at 4K. The 4K result of 51 FPS suggests the GPU is still the limiting factor even at the lowest settings, as a CPU-bound system would show less dramatic drops at higher resolutions. At High settings, the numbers are 50 FPS at 1080p, 41 FPS at 1440p, and 30 FPS at 4K. Ultra settings show 48 FPS at 1080p, 39 FPS at 1440p, and 28 FPS at 4K.

The consistent pattern across all settings — roughly a 40-45% reduction from 1080p to 4K — indicates the Arc B570's 10 GB VRAM and 380 GB/s bandwidth are insufficient to maintain framerates at higher resolutions. The CPU, with its high single-thread performance and 20 cores, is not the constraint. If the system were CPU-bound, the FPS at 1080p and 4K would be much closer, as the CPU's workload does not scale with resolution in the same way the GPU's does.

The data suggests that for this game, the optimal resolution is 1080p, where even Medium settings achieve 67 FPS. At 1440p, the Medium preset at 54 FPS is playable but close to the edge. At 4K, no setting provides a comfortable experience, with even Low at 51 FPS being marginal.

Measured FPS Breakdown

At 1920x1080, the system delivers its best performance. Low settings produce 86 FPS average, which is the highest result across all measurements. Medium settings achieve 67 FPS with a minimum of 57 FPS and maximum of 77 FPS, providing a stable experience. High settings drop to 50 FPS, and Ultra settings fall to 48 FPS. The transition from Low to Medium costs 19 FPS (22% reduction), while the jump from Medium to High costs 17 FPS (25% reduction). High to Ultra is only a 2 FPS difference, suggesting diminishing returns at the top end.

At 2560x1440, performance decreases noticeably. Low settings average 69 FPS, which is still smooth. Medium settings reach 54 FPS with a minimum of 46 FPS and maximum of 62 FPS, making it the recommended preset at this resolution. High settings drop to 41 FPS, and Ultra falls to 39 FPS. The scaling from 1080p to 1440p at Medium settings represents a 13 FPS loss (19% reduction), while at Low settings the loss is 17 FPS (20% reduction).

At 3840x2160, the GPU struggles. Low settings average 51 FPS, which is the only 4K preset above 50 FPS. Medium settings reach 40 FPS with a minimum of 34 FPS and maximum of 46 FPS. High settings drop to 30 FPS, and Ultra falls to 28 FPS. The 4K Medium result is 27 FPS lower than 1080p Medium (40% reduction), and the 4K Low result is 35 FPS lower than 1080p Low (41% reduction). The minimum FPS of 34 at 4K Medium indicates noticeable stuttering in complex scenes.

Across all settings and resolutions, the data shows a consistent pattern: the Arc B570 provides acceptable performance only at 1080p and 1440p with Medium or lower settings. The system's ability to run Microsoft Flight Simulator is fundamentally limited by the GPU, and users should set expectations accordingly. The measured numbers confirm that this combo is best suited for 1080p Medium gaming, where it achieves a stable 67 FPS with a 57 FPS minimum, offering the best balance of visual quality and smoothness.
