Microsoft Flight Simulator

# How This Combo Ranks

The AMD Ryzen 7 7700 paired with the Intel Arc B370 ranks 2770th out of 2996 tested combos in Microsoft Flight Simulator. This places the combination in the bottom 8% of all tested configurations, a position that reflects the GPU's severe limitations rather than the CPU's capabilities. The data shows a system that is fundamentally GPU-bound at every resolution and setting tier tested, with the processor's strong multi-threaded performance unable to compensate for the graphics card's modest output. In practical terms, this combo sits near the tail end of the performance distribution, meaning most other tested hardware pairs will deliver higher frame rates in this flight simulator.

The ranking is particularly striking because the CPU component alone performs respectably in general benchmarks. The Ryzen 7 7700 achieves an 87th percentile ranking among all CPUs, with an average benchmark score of 40081. Yet when paired with the Arc B370, the combined result falls dramatically. The discrepancy highlights how a weak GPU can drag down an otherwise capable processor. In Microsoft Flight Simulator, which demands substantial graphics throughput for terrain rendering and cockpit displays, the Arc B370 becomes the decisive bottleneck, capping performance well below what the Ryzen 7 7700 could otherwise support.

GPU Role

The Intel Arc B370 is an integrated graphics solution based on the Xe3-LPG architecture and Panther Lake chip, manufactured on Intel's 3 nm process. Its specifications immediately signal its limitations for a demanding title like Microsoft Flight Simulator. The GPU operates with a base clock of 300 MHz and a boost clock of 2400 MHz, with 1280 shading units, 40 texture mapping units, and 20 render output units. It includes 10 ray tracing cores and delivers 6.144 TFLOPS of FP32 compute performance. The memory subsystem is entirely system-shared, with no dedicated VRAM, relying on system memory bandwidth that is "System Dependent."

In benchmark terms, the Arc B370's lone 3DMark Steel Nomad DX12 score is 1184, placing it at the 5th percentile among all GPUs. Its nearest rivals are all legacy or low-end parts: the ATI Mobility Radeon HD 5570 (score 1186, delta -0.2%), the ATI Radeon HD 5770 (score 1190, delta -0.5%), the AMD Radeon HD 7650M (score 1192, delta -0.7%), and the AMD FirePro M2000 (score 1168, delta +1.4%). This places the Arc B370 in the company of graphics hardware from over a decade ago, which directly explains the measured FPS results in Microsoft Flight Simulator. The GPU's 25 W TDP and IGP form factor confirm its integrated nature, with display outputs described as "Portable Device Dependent."

The memory configuration is particularly problematic for a flight simulator that streams vast terrain and aircraft models. With "System Shared" memory, the GPU competes with the CPU for bandwidth on the system's DDR5 memory bus. While the Ryzen 7 7700 supports dual-channel DDR5 with 83.2 GB/s of memory bandwidth, the integrated GPU's share of that bandwidth is not fixed and can vary based on system load. In practice, this means the Arc B370 cannot sustain the texture throughput needed for high-detail flight simulation, leading to the low average frame rates observed across all settings.

Resolution Scaling

The resolution scaling data reveals a clear pattern of GPU-limited performance throughout. At 1920x1080 with Low settings, the combo achieves 50 FPS average. Moving to 2560x1440 Low, the average drops to 41 FPS, a reduction of 18%. At 3840x2160 Low, the average falls further to 30 FPS, another 27% reduction from 1440p. This scaling behavior shows that even at the lowest settings, the Arc B370 struggles to maintain playable frame rates as pixel count increases.

The pattern repeats across all settings tiers. At High settings, the progression is 30 FPS at 1080p, 24 FPS at 1440p, and 18 FPS at 4K. At Medium settings, the averages are 39 FPS at 1080p, 32 FPS at 1440p, and 23 FPS at 4K. At Ultra settings, the averages are 28 FPS at 1080p, 23 FPS at 1440p, and 17 FPS at 4K. The consistent pattern — roughly a 20-25% drop from 1080p to 1440p and another 25-30% drop from 1440p to 4K — indicates that the GPU's fill rate and shading capacity are the primary constraints. A CPU-bound scenario would show smaller FPS differences across resolutions, but here the resolution scaling is steep at every setting level.

The limiting component is unambiguously the Intel Arc B370. The Ryzen 7 7700's 8 cores and 16 threads, with a boost clock of 5.30 GHz, provide ample processing power for the simulation's physics and AI workloads. Yet the GPU's inability to render frames quickly enough means the CPU spends most of its time waiting. The measured FPS data shows no scenario where the combo exceeds 50 FPS, and even that only occurs at the lowest resolution and settings combination tested. For a flight simulator that benefits from smooth frame pacing, these results indicate a hardware pairing where the GPU severely bottlenecks the overall experience.

Measured FPS Breakdown

The complete set of measured frame rates for Microsoft Flight Simulator with the AMD Ryzen 7 7700 and Intel Arc B370 is as follows:

At 3840x2160 (4K):

• Low settings: 30 FPS average
• Medium settings: 23 FPS average, with a minimum of 20 FPS and maximum of 27 FPS
• High settings: 18 FPS average
• Ultra settings: 17 FPS average

At 2560x1440 (1440p):

• Low settings: 41 FPS average
• Medium settings: 32 FPS average, with a minimum of 27 FPS and maximum of 36 FPS
• High settings: 24 FPS average
• Ultra settings: 23 FPS average

At 1920x1080 (1080p):

• Low settings: 50 FPS average
• Medium settings: 39 FPS average, with a minimum of 33 FPS and maximum of 45 FPS
• High settings: 30 FPS average
• Ultra settings: 28 FPS average

The data reveals several important patterns. First, the difference between Low and Ultra settings at any given resolution is substantial but not overwhelming — at 1080p, the spread is 22 FPS (from 50 to 28), while at 4K it is 13 FPS (from 30 to 17). This suggests that the GPU is so constrained that even reducing settings yields limited gains. Second, the Medium settings tier consistently shows the largest gap between minimum and maximum FPS, indicating frame pacing variability at moderate graphics loads. Third, no setting at any resolution reaches 60 FPS, and only 1080p Low exceeds 45 FPS, confirming the combo's position in the bottom percentile of tested systems.

CPU Role

The AMD Ryzen 7 7700 is a Zen 4 architecture processor based on the Raphael codename, fabricated on TSMC's 5 nm process with 6,570 million transistors on a 71 mm² die. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.30 GHz. The cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. The CPU supports DDR5 memory with dual-channel configuration, offering 83.2 GB/s of memory bandwidth, and includes ECC memory support. It connects via PCIe Gen 5 with 24 lanes from the CPU, and integrates Radeon Graphics.

In synthetic benchmarks, the Ryzen 7 7700 demonstrates strong multi-threaded performance. Its Cinebench R23 multicore score is 18760, while the single-core score is 1930. Geekbench results show 15371 multicore and 2525 single-core. PassMark multithread score is 34470, with single-thread at 4063. The 3DMark results scale from 1049 single-thread to 8484 for 16 threads and 8479 for max threads. These numbers indicate a CPU that is well-equipped for the complex simulation workloads in Microsoft Flight Simulator, which includes flight dynamics calculations, weather simulation, and AI traffic management.

However, the CPU's role in this combo is secondary to the GPU's constraints. The processor's 87th percentile ranking among all CPUs and its average benchmark score of 40081 place it in the upper tier of desktop processors. Its nearest rivals — the AMD Ryzen AI 9 365, Intel Core 5 221E, AMD Ryzen 9 270, and Intel Core i9-13905H — all score within 0.6% of the Ryzen 7 7700, showing that this CPU is competitive with contemporary options. The launch MSRP is $329, with a TDP of 65 W and an unlocked multiplier for overclocking.

In Microsoft Flight Simulator specifically, the CPU's 8 cores and 16 threads provide sufficient parallelism for the game's multi-threaded rendering and simulation tasks. The 5.30 GHz boost clock ensures strong single-thread performance for the main game loop, which is critical in flight simulators that often have a primary simulation thread. The 32 MB L3 cache helps with terrain and scenery data locality. Yet none of these CPU strengths can overcome the GPU's fundamental limitation — the measured FPS data shows that even at the lowest settings and resolution, the system only achieves 50 FPS, a figure that would be much higher if the CPU were the limiting factor. The evidence points to a system where the Ryzen 7 7700 is waiting on the Intel Arc B370 at nearly every frame, making the GPU the clear performance ceiling for this combination.
