The combo ranks 2932 out of 3002 tested combinations in this game, placing it in the bottom percentile of all tested systems, which indicates that this pairing is not optimized for high-end gaming performance in this particular title. The data reveals a system where the integrated GPU becomes the primary constraint at higher resolutions, while the CPU demonstrates substantial headroom that remains underutilized in most gaming scenarios.

How This Combo Ranks

The combination of AMD Ryzen 9 8945HX and AMD Radeon 880M sits at rank 2932 out of 3002 tested combos in Pc Building Simulator, meaning only 70 combinations perform worse. This places the system firmly in the lower tier of tested hardware pairings, with approximately 97.7% of tested combos delivering better frame rates. The ranking reflects the fundamental imbalance between a high-end mobile CPU and an integrated GPU that, while capable for an IGP, cannot match discrete graphics solutions in sustained gaming workloads.

The CPU itself is a strong performer in synthetic benchmarks, with an average benchmark score of 76212, placing it in the 95th percentile of all CPUs. Its nearest rivals include the Intel Core Ultra 9 285HX at 76155 average score (0.1% slower), the AMD EPYC Embedded 8224P at 76492 (0.4% faster), the AMD Ryzen Threadripper PRO 9945WX at 76513 (0.4% faster), and the AMD Ryzen 9 9950X3D at 75779 (0.6% slower). These deltas are minimal, showing that the 8945HX competes directly with top-tier desktop and mobile processors in raw computational throughput.

The GPU, by contrast, has an average benchmark score of 8436, placing it in the 43rd percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce GTX 675MX at 8427 (0.1% slower), the NVIDIA GeForce MX330 at 8458 (0.3% faster), the AMD Radeon HD 8870M at 8462 (0.3% faster), and the AMD Radeon R9 M375X at 8325 (1.3% slower). These comparisons show the 880M performs comparably to older discrete mobile GPUs from roughly a decade ago, which explains its limitations in modern gaming titles.

The discrepancy between the CPU's top-tier percentile ranking and the GPU's mid-range percentile ranking creates a system where the weakest link determines overall gaming performance. In Pc Building Simulator, this means the GPU bottleneck dominates at higher resolutions, while at lower resolutions the CPU's capabilities become more relevant, though still constrained by the integrated graphics solution.

GPU Role

The AMD Radeon 880M is an integrated graphics processor built on the RDNA 3.5 architecture, manufactured on TSMC's 4 nm process node. It features a base clock of 400 MHz and a boost clock of 2900 MHz, with 768 shading units, 48 texture mapping units, and 16 raster operation units. The GPU includes 12 ray tracing cores and delivers a pixel rate of 46.40 GPixel/s, a texture rate of 139.2 GTexel/s, and FP32 performance of 4.454 TFLOPS. Memory is system shared, with bandwidth described as system dependent, meaning performance scales with the host system's memory configuration.

The integrated nature of this GPU means it relies on shared system memory rather than dedicated VRAM, which has significant implications for gaming performance. In Pc Building Simulator, the GPU's memory bandwidth limitations become more apparent at higher resolutions and settings, where texture data and frame buffers require greater memory throughput. The 880M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, ensuring compatibility with modern graphics APIs used by contemporary games.

In synthetic benchmarks, the 880M scores 535 in 3DMark Steel Nomad DX12, 31285 in Geekbench OpenCL, 40006 in Geekbench Vulkan, and 7615 in PassMark G3D. The PassMark DirectX tests show scores of 31 for DirectX 10, 73 for DirectX 11, 32 for DirectX 12, and 97 for DirectX 9, with a GPU compute score of 3719. These figures place the GPU in the 43rd percentile of all GPUs, indicating it performs better than many older integrated solutions but falls short of modern discrete graphics cards.

The GPU's thermal design power is rated at 15 W, which is remarkably low for the performance it delivers, but this also reflects its integration into the CPU package. The bus interface is PCIe 4.0 x8, which provides adequate bandwidth for the GPU's needs, though system shared memory access patterns can introduce latency compared to dedicated VRAM implementations. The pixel rate of 46.40 GPixel/s and texture rate of 139.2 GTexel/s suggest the GPU can handle moderate fill-rate demands, but the relatively low 4.454 TFLOPS FP32 performance limits its ability to handle complex shading workloads.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, codenamed Dragon Range, and manufactured on TSMC's 5 nm process node. It operates with a base clock of 2.50 GHz and a boost clock of 5.40 GHz, with a thermal design power of 55 W. The processor includes 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of L3 cache, totaling a substantial cache hierarchy that benefits workloads with high data reuse. Memory support includes DDR5 with a dual-channel bus and a memory bandwidth of 83.2 GB/s, though ECC memory is not supported. The CPU provides PCIe Gen 5 with 28 lanes from the CPU, and it integrates a Radeon 610M GPU as its basic graphics solution, separate from the discrete Radeon 880M used in this test configuration.

In synthetic benchmarks, the 8945HX demonstrates exceptional computational capabilities. Its Cinebench R15 multicore score reaches 4305, with a single-core score of 607. Cinebench R20 results show 17939 for multicore and 2532 for single-core, while Cinebench R23 delivers 42713 for multicore and 6030 for single-core. PassMark tests reveal a multithread score of 51405, single-thread score of 3907, floating point math score of 117453, integer math score of 195180, data compression score of 677755, data encryption score of 40836, extended instructions score of 49823, find prime numbers score of 262, random string sorting score of 78781, and physics score of 2168. These figures place the CPU in the 95th percentile of all CPUs, with an average benchmark score of 76212.

The CPU's nearest rivals in synthetic benchmarks include the Intel Core Ultra 9 285HX with an average score of 76155 (0.1% lower), the AMD EPYC Embedded 8224P at 76492 (0.4% higher), the AMD Ryzen Threadripper PRO 9945WX at 76513 (0.4% higher), and the AMD Ryzen 9 9950X3D at 75779 (0.6% lower). These tight margins demonstrate that the 8945HX performs at the top tier of available processors, whether mobile or desktop, in raw computing power.

For Pc Building Simulator, the CPU's role is significant because the game simulates hardware assembly and system diagnostics, which involves substantial computational logic beyond just rendering graphics. The 16 cores and 32 threads provide ample parallelism for physics calculations and system simulation tasks, while the high boost clock of 5.40 GHz ensures snappy single-threaded performance for UI interactions and game logic. However, the measured frame rates suggest that the CPU's capabilities are not fully utilized in this title, as the integrated GPU becomes the limiting factor at most resolutions and settings.

Measured FPS Breakdown

The measured frame rates reveal a clear pattern of performance degradation as resolution increases, with settings also playing a significant role. At 1920x1080, the system achieves an average of 105 FPS on Low settings, 74 FPS on Medium settings (with minimum 63 FPS and maximum 85 FPS), 52 FPS on High settings, and 50 FPS on Ultra settings. These figures show that at 1080p, the system can deliver playable frame rates across all settings, though Ultra settings drop below the 60 FPS threshold that many players consider smooth.

Moving to 2560x1440, the performance decreases noticeably. Low settings produce an average of 66 FPS, Medium settings average 47 FPS (with minimum 40 FPS and maximum 54 FPS), High settings average 33 FPS, and Ultra settings average 32 FPS. The drop from Low to Medium represents a 28.8% reduction in frame rate, while the difference between High and Ultra is minimal at only 1 FPS, suggesting that the GPU reaches its limits at this resolution regardless of the highest settings.

At 3840x2160, the system struggles to maintain playable frame rates. Low settings produce an average of 35 FPS, Medium settings average 25 FPS (with minimum 21 FPS and maximum 28 FPS), High settings average 17 FPS, and Ultra settings average 16 FPS. Only Low settings achieve frame rates that could be considered marginally playable, while Medium and above fall below 30 FPS, which is generally considered the minimum for acceptable gaming performance.

The data shows that the system's performance envelope spans from 105 FPS at 1080p Low to 16 FPS at 4K Ultra, representing a range of 89 FPS across the tested configurations. The minimum FPS values recorded only for Medium settings at each resolution show that the system maintains relatively stable frame delivery, with the gap between minimum and maximum at 1080p Medium being 22 FPS, at 1440p Medium being 14 FPS, and at 4K Medium being 7 FPS. This decreasing variance at higher resolutions suggests the GPU is working near its limits, leaving less headroom for frame rate fluctuations.

Resolution Scaling

The resolution scaling analysis reveals how the system's performance degrades as pixel count increases. From 1080p to 1440p, the average frame rates across all settings drop by approximately 37.1%, calculated by comparing the average of all settings at each resolution (70.25 FPS at 1080p versus 44.5 FPS at 1440p). From 1440p to 4K, the average frame rates drop by approximately 48.3%, from 44.5 FPS to 23.25 FPS. These scaling factors indicate that the GPU is the primary limiting component, as the performance loss exceeds what would be expected from the increased pixel count alone if the CPU were the bottleneck.

At Low settings, the frame rate drops from 105 FPS at 1080p to 66 FPS at 1440p, a 37.1% reduction, then to 35 FPS at 4K, a 47.0% reduction from 1440p. At Medium settings, the progression is 74 FPS to 47 FPS to 25 FPS, representing reductions of 36.5% and 46.8% respectively. High settings show 52 FPS to 33 FPS to 17 FPS, with reductions of 36.5% and 48.5%. Ultra settings display 50 FPS to 32 FPS to 16 FPS, with reductions of 36.0% and 50.0%.

These consistent reductions of roughly 36-37% from 1080p to 1440p and 47-50% from 1440p to 4K suggest that the GPU is operating at its compute and memory bandwidth limits. The slightly larger percentage drop at 4K indicates that the system shared memory bandwidth becomes more constrained at higher resolutions, where larger frame buffers require more frequent memory access. The CPU's high benchmark scores, including a Cinebench R23 multicore score of 42713 and a PassMark multithread score of 51405, suggest it has substantial headroom that remains unused in this gaming scenario.

The limiting component analysis points clearly to the GPU. The Radeon 880M's FP32 performance of 4.454 TFLOPS and its system shared memory architecture cannot sustain the frame rates that the CPU could theoretically support. If the CPU were the bottleneck, we would expect to see frame rates remain relatively constant across resolutions, as the CPU workload does not scale with pixel count in the same way as GPU workload. The data shows the opposite pattern, with frame rates decreasing significantly as resolution increases, confirming GPU-bound performance.

Settings Recommendations

Based on the measured frame rates, the optimal settings depend heavily on the target resolution. At 1920x1080, Medium settings provide the best balance of visual quality and performance, with an average of 74 FPS and a minimum of 63 FPS that stays above the 60 FPS threshold for smooth gameplay. High settings at 1080p deliver 52 FPS average, which is playable but may exhibit occasional stutter, while Ultra settings at 50 FPS average offer minimal visual improvement over High for a 3.8% performance cost.

At 2560x1440, the data shows that Low settings are the only configuration that consistently exceeds 60 FPS, with an average of 66 FPS. Medium settings at 47 FPS average and a minimum of 40 FPS provide a compromise for users who prioritize visual quality over frame rate stability, but the drop below 60 FPS may be noticeable. High and Ultra settings at 33 FPS and 32 FPS respectively are not recommended for this resolution, as the visual gains do not justify the significant performance penalty.

For 3840x2160, the measured data suggests that only Low settings approach playability, with an average of 35 FPS. Medium settings at 25 FPS average and a minimum of 21 FPS will feel sluggish, while High and Ultra at 17 FPS and 16 FPS respectively are effectively unplayable. Users targeting 4K should consider whether the simulation aspects of Pc Building Simulator are playable at these frame rates, as the game's slower pacing may tolerate lower FPS better than fast-action titles.

The best overall experience according to the measured rows is 1080p Medium settings, which delivers 74 FPS average with a tight frame time distribution (63-85 FPS range). This configuration maximizes the system's potential by keeping the GPU workload manageable while providing sufficient visual detail for a simulation game that focuses on hardware assembly and system diagnostics rather than fast-paced action. For users who prioritize frame rate above all else, 1080p Low at 105 FPS average offers the smoothest experience, while those who value visual fidelity might accept 1080p High at 52 FPS average as a reasonable trade-off.
