# Pc Building Simulator: AMD Ryzen 9 8945HX + AMD Radeon 760M

This combination pairs a flagship 16-core mobile processor with an entry-level integrated GPU, and the benchmark data for Pc Building Simulator shows a system that is decisively GPU-limited at every resolution and settings level. The AMD Ryzen 9 8945HX, with its 16 cores and 32 threads based on Zen 4 architecture, sits in the 95th percentile among all CPUs, while the AMD Radeon 760M integrated graphics, built on RDNA 3.0 with 512 shading units, lands in just the 35th percentile among all GPUs. The measured frame rates in this simulation title reflect that massive capability gap, with the integrated GPU acting as the clear bottleneck even at lower resolutions where CPU load typically increases.

Resolution Scaling

The frame rate curve from 1080p to 4K reveals a system that is almost entirely constrained by the integrated GPU's fill rate and shading throughput. At the Low preset, average FPS drops from 77 at 1920x1080 to 48 at 2560x1440, then to 25 at 3840x2160. That represents a 37.7% performance loss when moving from 1080p to 1440p, and a further 47.9% loss from 1440p to 4K. The scaling is nearly linear with pixel count, which is the classic signature of a GPU-bound scenario — the CPU has ample headroom to feed frames, but the Radeon 760M simply cannot rasterize pixels fast enough as resolution increases.

The Medium preset tells a similar story with slightly lower absolute numbers. Average FPS at 1080p Medium is 54, dropping to 34 at 1440p and 18 at 4K. The percentage drops are 37.0% and 47.1% respectively, almost identical to the Low preset scaling. This consistency across settings further confirms that resolution, not graphical complexity, is the primary factor limiting performance. The High preset shows the same pattern: 38 FPS at 1080p, 24 at 1440p, and 13 at 4K, with drops of 36.8% and 45.8%. Even the Ultra preset, which starts at just 36 FPS at 1080p, scales down to 23 at 1440p and 12 at 4K.

What the data does not show is any meaningful CPU involvement in this scaling. The Ryzen 9 8945HX, with a boost clock of 5.40 GHz and 64 MB of L3 cache, is capable of far higher frame rates in this genre than the measured numbers suggest. The fact that performance degrades proportionally to pixel count at every settings level indicates that the Radeon 760M's 16 ROPs and 32 texture mapping units are saturated well before the CPU's processing capacity becomes relevant. For a simulation game like Pc Building Simulator, which typically involves modest per-frame CPU work, the integrated GPU is the sole limiting component across the entire resolution spectrum.

GPU Role

The AMD Radeon 760M is an integrated graphics processor with a base clock of 800 MHz and a boost clock of 2599 MHz, built on TSMC's 4 nm process with RDNA 3.0 architecture. Its memory configuration is System Shared, meaning it draws from the same DDR5 pool as the CPU, with bandwidth listed as System Dependent. The GPU's 512 shading units, 32 TMUs, and 16 ROPs produce a peak FP32 throughput of 5.323 TFLOPS, which is modest by discrete GPU standards but respectable for an IGP. The 8 ray tracing cores are present but largely irrelevant at these performance levels.

The benchmark scores for this GPU place it in the 35th percentile among all GPUs, with an average benchmark score of 6019. Its nearest rivals in the database include the AMD Radeon RX 6400, which scores 6001 (0.3% higher), and the NVIDIA GeForce GTX 770M at 6000 (0.3% higher). The NVIDIA Quadro P2000 is 0.5% faster at 6049, while the NVIDIA RTX PRO 6000 Blackwell Server is 0.4% faster at 5996. These deltas are all within a fraction of a percent, meaning the Radeon 760M sits in an extremely tight performance cluster around the 6000-point mark. In practical terms, this GPU is roughly equivalent to a low-end discrete card from several generations ago.

In Pc Building Simulator specifically, the GPU's VRAM allocation is System Shared, which means there is no dedicated video memory to exhaust. This is relevant because the game's simulation mechanics and menu-heavy interface do not demand large texture pools. The measured frame rates, however, show that even without VRAM pressure, the GPU's raw shading power is insufficient for smooth gameplay at any resolution above 1080p Low. The 4K Ultra result of 12 FPS average is essentially a slideshow, while even 1080p High at 38 FPS falls short of the 60 FPS target many players expect. The GPU's DirectX 12 Ultimate support and Vulkan 1.4 API compatibility are technically modern, but the underlying hardware simply lacks the throughput for this title at playable settings.

How This Combo Ranks

The combination of AMD Ryzen 9 8945HX and AMD Radeon 760M ranks 2992 out of 3002 tested combos in Pc Building Simulator. This places it in the bottom 0.3% of all configurations, a remarkably low position that reflects the severe imbalance between the CPU and GPU. The Ryzen 9 8945HX alone scores an average benchmark of 76212, putting it in the 95th percentile of all CPUs with nearest rivals like the Intel Core Ultra 9 285HX (76155, 0.1% slower) and the AMD Ryzen 9 9950X3D (75779, 0.6% slower). This is a top-tier processor by any measure, with multi-core scores like 42713 in Cinebench R23 and 17939 in Cinebench R20.

The GPU, however, anchors the entire system. With an average benchmark score of 6019 and a 35th percentile ranking, the Radeon 760M is the weakest link in this pairing by an enormous margin. The delta between the CPU's 95th percentile and the GPU's 35th percentile is the defining characteristic of this combo. In a game like Pc Building Simulator, which is not particularly demanding on either component, the result is a system that underperforms even modest discrete GPU configurations. The combo rank of 2992 out of 3002 means that only 10 tested combinations score worse, and those are likely pairings with even weaker integrated graphics or severely outdated discrete cards.

This rank is particularly notable because the CPU is capable of so much more. The Ryzen 9 8945HX's data compression score of 677755 and multithread score of 51405 in Passmark indicate a processor that could easily drive a high-end discrete GPU in this game. The fact that it is paired with an IGP that ranks in the bottom third of all GPUs creates a system where the CPU's potential is entirely wasted. For any user considering this combo, the benchmark data makes it clear that the GPU must be upgraded to achieve reasonable performance in Pc Building Simulator, as no amount of CPU headroom can compensate for the Radeon 760M's limitations.

Settings Recommendations

Based on the measured FPS data, the only configuration that approaches playable performance is 1080p Low, which delivers an average of 77 FPS. This is the sole settings/resolution combination in the entire dataset that exceeds 60 FPS, and it does so with enough margin to handle minor scene complexity variations. The 1080p Medium preset drops to 54 FPS average, which is borderline — playable for a simulation game but with noticeable dips during busy scenes. The 1440p Low preset at 48 FPS is also potentially acceptable for users who prioritize resolution over smoothness, but it falls short of the 60 FPS threshold.

For users seeking the best balance of visual quality and performance, 1080p Medium is the recommended starting point. The measured range of 46 to 62 FPS at this setting (with an average of 54) shows that the system can occasionally hit 60 FPS but will spend significant time below it. The 1080p High preset at 38 FPS average is the highest visual quality that remains technically playable, though it requires a tolerance for sub-60 FPS gameplay. The 1080p Ultra preset at 36 FPS average is not worth the extra GPU load relative to High, as the performance difference is minimal while the visual uplift is marginal in a simulation title.

At 1440p, the Low preset at 48 FPS is the only realistic option, as Medium drops to 34 FPS and High falls to 24 FPS. The 4K resolution should be avoided entirely for gameplay; even the Low preset at 25 FPS is below playable thresholds, and Ultra at 12 FPS is unusable. The data suggests that users with 1440p or 4K displays should set the game to 1080p rendering if possible, as the GPU does not have the throughput to handle higher resolutions at acceptable frame rates. For a simulation game where precision mouse control matters, the 1080p Medium setting offers the best compromise between visual fidelity and the responsiveness needed for building and managing PC components.

Measured FPS Breakdown

At 1920x1080, the system delivers its best results across all settings. The Low preset averages 77 FPS, which is the only measured configuration above 60 FPS. Medium averages 54 FPS with a measured range of 46 to 62 FPS, providing the most complete picture of real-world variability. High averages 38 FPS, and Ultra averages 36 FPS. The difference between High and Ultra is just 2 FPS, suggesting that Ultra settings impose a negligible additional cost over High at this resolution, likely due to the GPU being already saturated.

Moving to 2560x1440, performance drops significantly. Low averages 48 FPS, which is still usable but below the 60 FPS target. Medium averages 34 FPS with a range of 29 to 39 FPS, showing tighter minimums than at 1080p. High averages 24 FPS, and Ultra averages 23 FPS. The gap between High and Ultra narrows to just 1 FPS at 1440p, confirming that the GPU is fully bottlenecked and additional settings have almost no impact on the already-limited frame rate.

At 3840x2160, all settings produce unplayable results. Low averages 25 FPS, Medium averages 18 FPS with a range of 15 to 21 FPS, High averages 13 FPS, and Ultra averages 12 FPS. The Medium preset is the only 4K configuration with recorded minimum and maximum values, showing a tight 15-21 FPS band that indicates consistent GPU saturation. The scaling from 1440p to 4K at every settings level is roughly proportional to the pixel count increase, confirming that the Radeon 760M's rendering pipeline is the definitive performance ceiling for this combination.
