# Microsoft Flight Simulator: Intel Core i5-13400F + AMD Radeon RX 7700

The pairing of Intel's Core i5-13400F with AMD's Radeon RX 7700 produces a distinctly CPU-bound experience in Microsoft Flight Simulator, where the 10-core Raptor Lake processor becomes the primary limiter as resolution drops. Across the measured resolution spectrum, this combo delivers playable frame rates at 4K, solid performance at 1440p, and triple-digit numbers at 1080p, but the scaling patterns reveal that the RX 7700 has headroom left untapped. The data shows a system that handles the game's demanding flight simulation workloads with consistent results, though the gap between low and ultra settings at each resolution tells a clear story about where the bottleneck resides.

Resolution Scaling

The frame rate progression from 1080p to 4K follows an expected downward trajectory, but the magnitude of the drops reveals the CPU's influence. At High settings, the average FPS falls from 74 at 1920x1080 to 60 at 2560x1440, a reduction of 14 frames, then to 44 at 3840x2160, another 16-frame drop. This pattern—roughly a 19% decline from 1080p to 1440p and a further 27% decline to 4K—indicates that the GPU is increasingly the limiting component as pixel count rises, yet the 1080p result of 74 FPS is notably lower than what the RX 7700's raw compute would suggest capable.

Low settings amplify this CPU-bound signature dramatically. At 1080p Low, the combo hits 126 FPS average, but 1440p Low drops to 102 FPS (a 19% reduction) and 4K Low falls to 75 FPS (another 26% cut). The fact that 4K Low (75 FPS) still exceeds 1080p Ultra (70 FPS) demonstrates that the Radeon GPU has substantial performance reserves; the CPU is what prevents even higher numbers at lower resolutions. Medium settings show a similar staircase: 98 FPS at 1080p, 79 at 1440p, and 59 at 4K, with the 4K Medium result including a minimum FPS of 50 and maximum of 67.

Ultra settings compress the resolution scaling curve. The spread from 1080p Ultra (70 FPS) to 4K Ultra (42 FPS) is 28 frames, compared to the Low settings spread of 51 frames. This convergence at higher settings is a classic sign of GPU saturation—when the render load is heavy enough, the graphics card becomes the bottleneck regardless of resolution, and the CPU's limitations fade into the background. The data suggests that users targeting 60+ FPS will find 1440p High (60 FPS) as the sweet spot, while 4K requires either Medium settings (59 FPS) or accepting sub-60 performance on High.

GPU Role

The AMD Radeon RX 7700 brings 16 GB of GDDR6 memory on a 256-bit bus, yielding 624.1 GB/s of bandwidth—a configuration that proves ample for Microsoft Flight Simulator's texture-heavy environments. The GPU's boost clock of 2459 MHz and game clock of 2041 MHz, built on the RDNA 3.0 architecture with 2560 shading units, deliver a PassMark G3D score of 20974. This places the card at the 58th percentile of all GPUs, with nearest rivals including the NVIDIA GeForce RTX 3060 Ti (avgScore 16129, deltaPct -1.7) and AMD Radeon RX 9060 (avgScore 16014, deltaPct -1).

The VRAM allocation is never a limiting factor in this game, as even the most demanding 4K Ultra preset fails to stress the 16 GB pool. The GPU's 40 ray accelerators and 96 ROPs handle the game's volumetric clouds and terrain rendering without obvious stutter, though the minimum FPS of 50 at 4K Medium suggests occasional dips in complex scenes. The Radeon's FP32 throughput of 25.18 TFLOPS provides substantial compute headroom, yet the benchmark results show the card rarely operating at full utilization except at 4K Ultra, where the 42 FPS average indicates genuine GPU-bound performance.

Interestingly, the RX 7700's nearest rivals by average benchmark score include much older and less capable cards—the AMD Radeon R9 370X (avgScore 15862, deltaPct -0.1) and AMD Radeon Pro W5500 (avgScore 15679, deltaPct 1.1)—which speaks to the synthetic benchmark's weighting rather than real-world gaming performance. In Microsoft Flight Simulator specifically, the GPU's role is secondary to the CPU at lower resolutions, but at 4K the card's 16 GB memory and high bandwidth become decisive. The measured FPS at 4K Ultra (42) versus 4K Low (75) shows a 33-frame swing purely from settings, confirming the GPU's ability to scale its workload across the resolution range when given the chance.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on Raptor Lake architecture, with a base clock of 2.50 GHz and boost clock of 4.60 GHz. Its 20 MB shared L3 cache and 80 KB L1 per core provide the kind of low-latency memory access that flight simulators crave, as they must continuously stream terrain data and aircraft physics calculations. The CPU's Cinebench R23 multicore score of 22604 and single-core score of 3191 place it in the 77th percentile of all CPUs, with nearest rivals including the AMD Ryzen 9 6900HS (avgScore 25284, deltaPct 0) and AMD Ryzen 7 6800H (avgScore 25201, deltaPct 0.4).

The single-threaded performance is particularly relevant for Microsoft Flight Simulator, which historically relies heavily on one or two main threads for simulation logic. The 13400F's 3DMark single-thread score of 960 and 2-thread score of 1880 indicate strong per-core capability, yet the game's engine still leaves performance on the table. At 1080p Low, the CPU can only push 126 FPS, which is respectable but far below what the GPU could deliver if unconstrained. The scaling pattern—where 1080p Ultra (70 FPS) barely exceeds 4K Low (75 FPS) in raw output—shows that the CPU's thread scheduling and cache hierarchy are the deciding factors in this pairing.

The 65W TDP and locked multiplier (no overclocking) mean the processor operates within conservative thermal bounds, but its dual-channel DDR4/DDR5 memory support and PCIe Gen 5 interface provide adequate data pathways. The CPU's PassMark multithread score of 25032 and single-thread score of 3634 confirm its position as a mid-range performer that competes with the Ryzen 9 6900HS and Ryzen 5 5600X3D (avgScore 25365, deltaPct -0.3). In this game, the 10-core configuration with 16 threads appears to hit a sweet spot—enough cores for background tasks and simultaneous rendering threads, but the game's primary simulation thread remains the throughput limiter.

How This Combo Ranks

Within the benchmark database's tested combinations, this Intel Core i5-13400F + AMD Radeon RX 7700 pairing ranks 1324 out of 2996 combos in Microsoft Flight Simulator. That places it in the 44th percentile of all tested systems, a middling position that reflects the CPU's bottlenecking tendencies in this particular title. The rank is somewhat surprising given the individual component percentiles—CPU at 77th and GPU at 58th—but flight simulation's unique workload demands more from the processor than typical games.

The combo's position suggests that many systems with slower GPUs but faster CPUs achieve better frame rates in this game. For instance, a pairing with a higher-end CPU and a comparable or slightly weaker GPU would likely rank higher, since the game's performance ceiling at 1080p and 1440p is set by the processor. The fact that 4K Ultra (42 FPS) and 1080p Ultra (70 FPS) differ by only 28 frames, while low settings across the same resolution range differ by 51 frames, indicates that the combo's rank would improve if the GPU were more often the limiting factor.

The rank also reflects the game's release date of August 2020, predating both components' launches—the CPU in January 2023 and the GPU in September 2025. This generational mismatch means the hardware is optimized for newer titles, yet it still delivers playable performance in this older simulator. The data suggests that users with this combo should prioritize CPU-affecting settings (like draw distance and object density) over pure resolution scaling, as the processor's 16 threads are the primary constraint across most of the measured scenarios.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. Low settings produce an average of 126 FPS, Medium 98 FPS (with a minimum of 84 and maximum of 113), High 74 FPS, and Ultra 70 FPS. The jump from Low to Medium is 28 FPS, but the gap from Medium to High (24 FPS) and High to Ultra (4 FPS) narrows considerably, indicating diminishing returns from graphics settings above Medium. The 1080p results confirm that the CPU is the limiting factor, as even the lowest settings cannot push past 126 FPS.

At 2560x1440, the average FPS values are 102 (Low), 79 (Medium, with a minimum of 67 and maximum of 91), 60 (High), and 57 (Ultra). The 1440p results show a more balanced CPU-GPU relationship—the drop from Low to Medium is 23 FPS, and from High to Ultra is only 3 FPS. The 60 FPS High result is notable for being exactly at the refresh rate threshold of many monitors, making this the recommended settings/resolution combination for smooth gameplay. The minimum FPS of 67 at Medium suggests occasional frame dips during complex scenes, but overall the 1440p experience remains stable.

At 3840x2160, the performance becomes GPU-bound. Low settings average 75 FPS, Medium 59 FPS (with a minimum of 50 and maximum of 67), High 44 FPS, and Ultra 42 FPS. The 4K results show a compressed range—only 33 FPS separates Low from Ultra—compared to the 56 FPS spread at 1080p. This compression is the clearest evidence that the RX 7700 is fully utilized at 4K, particularly at Ultra settings where the 42 FPS average represents the hardware's realistic ceiling in this game. The 4K Medium result's minimum of 50 FPS indicates that even at this resolution, the combo can maintain playable frame rates with occasional dips below 60.
