Microsoft Flight Simulator

Microsoft Flight Simulator is a notoriously demanding title, and the combination of the AMD Ryzen 7 3700X and Intel Arc B570 produces a specific performance profile that hinges heavily on resolution. The measured data reveals a system that is capable of smooth flight at 1080p but struggles to maintain playable framerates at 4K, with the GPU clearly becoming the primary bottleneck as pixel count increases. This analysis breaks down the measured FPS across various settings and resolutions, examining the distinct roles the CPU and GPU play in this demanding simulation.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent across all settings, underscoring the GPU-bound nature of Microsoft Flight Simulator at higher resolutions. At Low settings, the average framerate falls from 86 FPS at 1920x1080 to 69 FPS at 2560x1440, and finally to 51 FPS at 3840x2160. This represents a significant 41% performance loss when moving from 1080p to 4K, a clear indication that the Intel Arc B570's rendering capabilities are being taxed heavily by the increased pixel workload.

The trend continues with Medium settings, where the average FPS drops from 67 at 1080p to 54 at 1440p, and then to 40 at 4K. At High settings, the framerate declines from 50 FPS at 1080p to 41 FPS at 1440p, and bottoms out at 30 FPS at 4K. The Ultra preset shows the most dramatic scaling challenge, with averages of 48, 39, and 28 FPS across 1080p, 1440p, and 4K respectively. The data indicates that at 4K, the system is consistently operating at or below the 30 FPS threshold, which is generally considered the minimum for a playable experience in a flight simulator.

This scaling pattern suggests that while the Ryzen 7 3700X provides a solid foundation, the Arc B570 is the limiting component at 4K. The gap between 1080p and 1440p performance is notable but manageable, whereas the jump to 4K causes a disproportionate drop, indicating the GPU's memory bandwidth and compute resources are overwhelmed. The 10 GB of GDDR6 memory and 160-bit bus width, while adequate for 1080p and 1440p, likely contribute to the significant frame rate collapse at 4K Ultra, where texture data and rendering complexity increase exponentially. The measured data clearly shows that 4K is not a viable target for this pairing, even on the Low preset, which only manages an average of 51 FPS.

CPU Role

The AMD Ryzen 7 3700X, with its 8 cores and 16 threads based on the Zen 2 architecture, provides a robust processing foundation for Microsoft Flight Simulator. The CPU's base clock of 3.60 GHz and boost clock of 4.40 GHz are the key drivers for the simulation's complex physics and AI calculations. Benchmark results show the processor achieving a strong 2092 score in Cinebench R15 multi-core and 204 in single-core, indicating a balanced capability for both heavily threaded simulation logic and the primary game thread that handles flight dynamics.

The data suggests that the CPU is not the primary constraint in this configuration, as the framerate scaling is more closely tied to resolution changes than to CPU-bound tasks. At 1080p Low, the system achieves 86 FPS, which is a very high framerate for this simulator and suggests the CPU is capable of feeding frames well beyond what the GPU can render at higher resolutions. The processor's 32 MB of L3 cache helps maintain data locality for the large world-streaming assets in the game, while its PassMark multi-thread score of 22458 places it in the 84th percentile of all CPUs, confirming its strong multi-threaded performance.

The Ryzen 7 3700X's performance is closely matched by its nearest rivals, with a negligible 0.1% difference compared to the AMD Ryzen AI 7 350 and AMD EPYC 4244P. It is also just 0.2% behind the Intel Core i5-13450HX and 0.5% ahead of the Intel Core Ultra 7 165H. This indicates that the CPU is performing exactly as expected for its class, providing a stable platform that does not introduce significant frame pacing issues. The 65W TDP is a modest power envelope for an 8-core processor, allowing for consistent sustained performance without thermal throttling in a typical desktop chassis. The CPU's role is to maintain a consistent frame delivery, which it does admirably, as evidenced by the fact that even at 1080p Ultra, the framerate only drops to 48 FPS, a figure that is more likely constrained by the GPU's shading and texture throughput than by CPU processing power.

GPU Role

The Intel Arc B570 is the defining component in this system's gaming performance, and its characteristics directly explain the measured FPS figures. Built on the Xe2-HPG architecture with 2304 shading units, the GPU has a base and boost clock of 2500 MHz, delivering 11.52 TFLOPS of FP32 compute. This raw compute power is sufficient for 1080p gaming, but the 10 GB of GDDR6 memory on a 160-bit bus with 380.0 GB/s of bandwidth becomes a limiting factor at higher resolutions. The 4K Ultra score of 28 FPS is a direct consequence of this memory constraint, as the GPU must manage significantly larger texture sets and render targets.

The GPU's benchmark scores provide context for its positioning. Its PassMark G3D score of 14195 places it in the 65th percentile of all GPUs, and its performance is nearly identical to the NVIDIA GeForce RTX 3070 Mobile, which it trails by just 0.1%. It also sits within a 0.5% margin of the Intel Arc A750 and AMD Radeon R9 M390X, and is 0.4% ahead of the NVIDIA Quadro M4000M. This places the B570 in a competitive mid-range tier, which aligns with its 1080p and 1440p performance profile. The 18 ray tracing cores are present, but the low framerates at 4K suggest that the GPU is not fully utilizing these features in this simulator, likely due to the overall rendering load.

The GPU's memory bandwidth of 380.0 GB/s, while respectable, is not enough to sustain high framerates at 4K in a game as demanding as Microsoft Flight Simulator. The measured data shows a clear pattern: at 1080p, the GPU has enough bandwidth and compute to deliver playable framerates across all settings, from 86 FPS on Low to 48 FPS on Ultra. At 1440p, performance degrades but remains playable, with the Low preset hitting 69 FPS and Ultra dropping to 39 FPS. However, at 4K, the GPU is overwhelmed, with all presets failing to reach 60 FPS and the Ultra preset falling to a slideshow-like 28 FPS. The dual-slot cooler and 150W TDP suggest the card can sustain its boost clock under load, but the architectural limits of the 160-bit memory interface are the primary obstacle to high-resolution performance.
