# How This Combo Ranks

The Intel Core Ultra 7 265K paired with the Intel Arc B370 ranks 2770th out of 2996 tested combos in Microsoft Flight Simulator, placing it in the bottom 8% of all configurations. This is a decisively weak result for a CPU that otherwise sits in the 94th percentile among all processors. The data reveals a stark mismatch: the Core Ultra 7 265K is a high-end desktop part, but the Arc B370 is an integrated graphics solution that ranks in the 5th percentile among all GPUs. The combination produces frame rates that are largely unplayable at most settings and resolutions.

The pairing's poor standing becomes clearer when examining the GPU's benchmark context. The Arc B370's average benchmark score of 1184 places it within 1.4% of the AMD FirePro M2000 and just 0.2% behind the ATI Mobility Radeon HD 5570. These are legacy mobile and entry-level workstation parts from a different era. The CPU, by contrast, scores 70879 on average, sitting within 0.2% of the Intel Xeon 6511P and 1% ahead of the Intel Core i7-14700KF. The delta between the two components' competitive positions could hardly be more extreme.

What this means in practice is that the CPU is almost never the limiting factor. Even at 1080p Low, where the combo reaches its peak of 50 FPS, the system is still GPU-bound. The Core Ultra 7 265K has 20 cores and 20 threads, with a boost clock of 5.50 GHz, yet the Arc B370's integrated nature caps performance at levels that would embarrass a desktop GPU from a decade ago. The combination's 2770th place ranking reflects this bottleneck almost entirely on the graphics side.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a system that is overwhelmingly GPU-limited across the entire measured range. At Low settings, the drop from 1080p to 4K is 20 FPS (from 50 to 30), a 40% reduction. At High settings, the drop is 12 FPS (from 30 to 18), a 40% reduction. At Medium, the drop is 16 FPS (from 39 to 23), a 41% reduction. At Ultra, the drop is 11 FPS (from 28 to 17), a 39% reduction. The consistency of this ~40% penalty across all settings is a signature of pure pixel-throughput limitation.

The pattern holds when moving from 1440p to 4K. At Low, the drop is 11 FPS (from 41 to 30), a 27% reduction. At Medium, the drop is 9 FPS (from 32 to 23), a 28% reduction. At High, the drop is 6 FPS (from 24 to 18), a 25% reduction. At Ultra, the drop is 6 FPS (from 23 to 17), a 26% reduction. Again, the proportional penalty is nearly identical across settings, confirming that resolution, not scene complexity or settings overhead, dominates the performance curve.

The 1080p to 1440p transition shows a smaller but still significant drop. At Low, 50 to 41 FPS (18% reduction). At Medium, 39 to 32 FPS (18%). At High, 30 to 24 FPS (20%). At Ultra, 28 to 23 FPS (18%). The uniformity of these percentages — roughly 18-20% for the 1.78x pixel increase from 1080p to 1440p, then another 25-28% for the 2.25x pixel increase from 1440p to 4K — indicates that the Arc B370's render output units and texture units are saturated even at the lowest settings.

The limiting component is unambiguous. A CPU with 20 cores, a 5.50 GHz boost clock, and a 94th percentile ranking would not cause frame rates to scale so predictably with pixel count. The Arc B370, with only 20 ROPs and a 6.144 TFLOPS FP32 throughput, is the constraining factor at every measured point. Even at 1080p Low, the system only reaches 50 FPS, a figure that suggests the integrated GPU is already near its ceiling with minimal graphics load.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results, though none are particularly strong. Low settings produce an average of 50 FPS. Medium settings yield 39 FPS average, with a minimum of 33 and a maximum of 45. High settings drop to 30 FPS average. Ultra settings produce 28 FPS average. The full range from Low to Ultra spans only 22 FPS, from 50 down to 28, which is a narrow band for a 1080p resolution.

At 2560x1440, the performance degrades noticeably. Low settings average 41 FPS. Medium settings average 32 FPS, with a minimum of 27 and a maximum of 36. High settings average 24 FPS. Ultra settings average 23 FPS. The spread from Low to Ultra here is 18 FPS, slightly narrower than at 1080p, suggesting that the GPU is even more constrained as resolution increases.

At 3840x2160, the combo falls below playable thresholds across the board. Low settings average 30 FPS. Medium settings average 23 FPS, with a minimum of 20 and a maximum of 27. High settings average 18 FPS. Ultra settings average 17 FPS. The Low-to-Ultra spread compresses to 13 FPS, indicating that the Arc B370 is hitting hard architectural limits at 4K regardless of settings.

The Medium preset is the only settings level that includes full min/max data across all three resolutions. At 1080p Medium, the 33-45 FPS range shows noticeable frame time variance. At 1440p Medium, the 27-36 FPS range tightens slightly. At 4K Medium, the 20-27 FPS range compresses further. This trend suggests that as resolution climbs, the GPU becomes so saturated that frame rate variability diminishes — the system simply cannot push more frames regardless of scene complexity.

The delta between Low and Ultra is consistent across resolutions: 22 FPS at 1080p, 18 FPS at 1440p, and 13 FPS at 4K. This shrinking delta is a classic sign of a GPU that is bandwidth or fill-rate limited. The Arc B370's system-shared memory and system-dependent bandwidth mean that at 4K, the memory subsystem is likely the final bottleneck, not the shading units or ROPs.

Settings Recommendations

The measured data points to 1080p Low as the only configuration that approaches a playable experience, with an average of 50 FPS. Even this setting falls short of the 60 FPS threshold that flight simulation enthusiasts typically prefer for smooth panning across dense scenery. The 1080p Medium preset, at 39 FPS average with a 33 FPS minimum, is a compromise that maintains some visual fidelity but risks noticeable stutter during low-altitude flyovers or complex airport approaches.

For users who prioritize frame rate above all else, 1080p Low is the clear choice. The 50 FPS average is the highest figure recorded in the entire measured set. However, even this setting does not provide headroom for the frame time spikes that are common in Microsoft Flight Simulator when loading new scenery tiles. The 1080p Medium preset offers a 33 FPS minimum, which is only 5 FPS lower than the Low preset's average, suggesting that Medium at 1080p may actually provide a more consistent experience despite the lower average.

At 1440p, no settings level delivers a comfortable experience. Low averages 41 FPS, but Medium drops to 32 FPS with a 27 FPS minimum. High and Ultra at 1440p produce 24 and 23 FPS respectively, which are below the threshold for smooth simulation. The data suggests that 1440p should be avoided entirely unless the user accepts Low settings and the associated visual compromises.

At 4K, the combo is effectively unusable for flight simulation. Even Low settings average only 30 FPS, and Medium drops to 23 FPS with a 20 FPS minimum. The 17-18 FPS figures at High and Ultra are slideshow territory. No settings recommendation can salvage 4K performance with this GPU.

The best overall experience per the measured rows is 1080p Medium. It provides a 39 FPS average, which is within 11 FPS of the Low preset's peak, while offering significantly better visual quality. The 33 FPS minimum is the highest minimum recorded at any resolution and settings combination that includes min/max data. Users who cannot tolerate the visual downgrade of Low but still want playable performance should select 1080p Medium. Those who demand the highest possible frame rate should use 1080p Low, accepting that the visual quality will be minimal.

CPU Role

The Intel Core Ultra 7 265K is a 20-core, 20-thread processor built on Arrow Lake architecture using a 3 nm process node from TSMC. It has a base clock of 3.90 GHz and a boost clock of 5.50 GHz, with a 125 W TDP. The CPU features 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 30 MB of shared L3 cache. It supports dual-channel DDR5 memory with a bandwidth of 102.4 GB/s and includes ECC memory support. The integrated graphics are Arc Xe-LPG Graphics with 64 execution units.

In the context of Microsoft Flight Simulator, the CPU's role is largely theoretical because the GPU bottleneck is so severe. The 265K's 94th percentile standing among all CPUs means it has ample headroom for the simulation's complex physics, weather modeling, and AI traffic calculations. The 20 cores and 20 threads provide substantial parallel processing capability, and the 5.50 GHz boost clock ensures strong single-thread performance for the game's primary render thread.

The nearest CPU rivals illustrate the 265K's position. It scores 70879 on average, which is 0.2% lower than the Intel Xeon 6511P's 71051 and 0.7% lower than the Intel Xeon Platinum 8270's 71370. It is 1% ahead of the Intel Core i7-14700KF (70163) and 1.3% ahead of the AMD Ryzen 7 9700F (69996). These deltas are minor, indicating that the 265K is squarely in the upper tier of desktop processors.

However, this CPU strength does not translate into game performance because the Arc B370 cannot utilize it. The GPU's 1280 shading units, 40 texture mapping units, and 20 render output units are simply too few for a demanding flight simulator at modern resolutions. The 6.144 TFLOPS FP32 throughput and 96.00 GTexel/s texture rate are entry-level figures, and the 25 W TDP confirms that this is an integrated solution, not a discrete graphics card.

The measured frame rates show almost no sign of CPU limitation. If the CPU were the bottleneck, we would expect to see frame rates that plateau regardless of resolution or settings. Instead, the data shows consistent scaling with pixel count and settings level, which is the hallmark of a GPU-bound system. The 265K is effectively idle waiting for the Arc B370 to deliver frames.

The CPU's 17,800 million transistors and 243 mm² die size place it among the most complex desktop processors available. Its memory bandwidth of 102.4 GB/s is more than sufficient for the game's streaming requirements. But none of this matters when the GPU cannot render frames fast enough to exercise the CPU's capabilities. The combo ranking of 2770th out of 2996 is a direct consequence of this mismatch. Users pairing this CPU with a discrete GPU would see dramatically different results, but with the Arc B370, the CPU's potential is entirely unrealized in Microsoft Flight Simulator.
