# Pc Building Simulator with AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 5050

This simulation title proves unusually demanding at higher resolutions, with the data showing a clear GPU-bound pattern as pixel count climbs. The Ryzen 9 8945HX provides ample headroom, but the RTX 5050's 8 GB GDDR6 frame buffer and 128-bit memory interface become the decisive factors at 4K. The measured results across twelve configurations reveal a combo that excels at 1080p, remains viable at 1440p, and struggles to maintain playable frame rates at 2160p with higher quality presets.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent across all settings, indicating that the NVIDIA GeForce RTX 5050 is the primary limiting component as resolution increases. At Low settings, the average FPS falls from 196 at 1920x1080 to 124 at 2560x1440, then to 65 at 3840x2160. That represents a 37% reduction moving from 1080p to 1440p, and another 48% drop going from 1440p to 4K. The pattern is similar at Medium settings, where averages go from 139 to 88 to 46 across the three resolutions.

The scaling behavior at High and Ultra presets tells the same story with slightly different numbers. At High, the combo delivers 98 FPS at 1080p, 62 at 1440p, and just 32 at 4K. Ultra settings produce 93, 59, and 31 FPS respectively. Notably, the gap between High and Ultra at 1080p is only 5 FPS, while at 4K the difference narrows to just 1 FPS — both presets are hitting the same GPU ceiling. This compression at 4K strongly suggests the RTX 5050 runs out of raw throughput and memory bandwidth before the quality preset becomes the bottleneck.

The 1440p to 4K transition is particularly punishing. At Medium settings, the drop from 88 to 46 FPS means losing nearly half the performance. The RTX 5050's 320.0 GB/s memory bandwidth and 8 GB capacity are likely strained by the four-fold increase in pixel count from 1440p to 4K. The Ryzen 9 8945HX, with its 16 cores and 32 threads, shows no signs of holding the system back — the FPS scaling follows what you would expect from a GPU-limited scenario rather than a CPU-limited one.

FAQ

Q: Can this combo handle 4K gaming in Pc Building Simulator?

A: Only at Low settings, where the average FPS reaches 65. At Medium, High, and Ultra, averages fall to 46, 32, and 31 respectively. The 4K Medium result has a minimum of 39 FPS, but the High and Ultra presets are below playable thresholds.

Q: What is the best resolution for this pairing in this game?

A: 1920x1080 is clearly the sweet spot. All four settings presets deliver playable averages: 196 FPS at Low, 139 at Medium, 98 at High, and 93 at Ultra. The 2560x1440 results are also usable, with Low and Medium hitting 124 and 88 FPS, but High and Ultra dip to 62 and 59.

Q: How does the RTX 5050 compare to its nearest rivals?

A: The RTX 5050's average benchmark score of 21035 puts it 0.6% behind the AMD Radeon RX Vega M GL, 1% behind the AMD Radeon HD 8970M, and 1.6% ahead of the AMD Radeon RX 5600 XT. It also trails the NVIDIA RTX A4000 Mobile by 1.6%.

Q: Is the Ryzen 9 8945HX strong enough for this title?

A: Yes. The CPU's multi-threaded performance is substantial, with a Cinebench R23 multi-core score of 42713. Its single-core score of 6030 in the same test is equally strong. The CPU ranks in the 95th percentile among all tested processors.

Q: Does the game benefit from the CPU's 32 threads?

A: Pc Building Simulator's simulation nature likely uses multiple cores, but the FPS scaling across resolutions indicates GPU limitation. The Ryzen 9 8945HX provides enough headroom that frame rates are dictated by the RTX 5050 rather than the processor.

A: The measured average is 88 FPS, with a minimum of 74 and maximum of 101. This is the most balanced configuration in the dataset, offering smooth gameplay without the FPS sacrifice seen at High or Ultra settings.

How This Combo Ranks

The combination of the AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5050 ranks 2390 out of 3002 tested combos in Pc Building Simulator. That places this pairing in the bottom 20% of all combinations tested, which may seem surprising given the strong CPU performance. The explanation lies in the GPU's relative standing — the RTX 5050 sits in the 66th percentile among all GPUs, while the CPU is in the 95th percentile. The GPU drags the overall combo ranking down.

The ranking suggests that while this system is far from the weakest tested, it is not optimized for maximum performance in this simulation title. The gap between CPU and GPU capability is notable: the Ryzen 9 8945HX's average benchmark score of 76212 puts it within 0.1% of the Intel Core Ultra 9 285HX and 0.6% behind the AMD Ryzen 9 9950X3D. The RTX 5050, by contrast, trades blows with much older mobile and desktop parts like the Radeon HD 8970M and RX 5600 XT.

For context, the CPU's nearest rivals include the AMD EPYC Embedded 8224P and AMD Ryzen Threadripper PRO 9945WX, both within 0.4% of its average score. This is a top-tier mobile processor paired with a mid-range GPU, resulting in a combo that underperforms relative to what the CPU alone might suggest. The rank of 2390 reflects the GPU bottleneck that appears at 1440p and becomes severe at 4K.

Measured FPS Breakdown

At 1920x1080, the RTX 5050 delivers strong results across all presets. Low settings produce an average of 196 FPS, Medium reaches 139 with a minimum of 118 and maximum of 160, High hits 98, and Ultra achieves 93. The gap between Low and Medium is 57 FPS, while the gap between High and Ultra is just 5 FPS — indicating diminishing returns beyond Medium settings.

Moving to 2560x1440, the averages drop noticeably. Low settings still deliver a smooth 124 FPS, Medium averages 88 with a range of 74 to 101, High falls to 62, and Ultra bottoms out at 59. The Medium preset at 1440p offers the best balance in the entire dataset, with a minimum that stays above 60 FPS.

At 3840x2160, the picture changes dramatically. Low settings average 65 FPS, which is playable but not high-refresh territory. Medium drops to 46 FPS with a minimum of 39 and maximum of 53. High and Ultra average 32 and 31 FPS respectively, which are below the threshold for smooth gameplay. The 4K results clearly show the RTX 5050's limitations, as even the Low preset cannot maintain the frame rates seen at lower resolutions.

The data also reveals interesting scaling patterns between settings at each resolution. At 1080p, Ultra is only 5% slower than High, but Medium is 42% faster than High. At 1440p, the differences compress: Ultra is 5% slower than High, while Medium is 42% faster. At 4K, Low is 102% faster than High, but High and Ultra are nearly identical. This suggests the GPU saturates at 4K regardless of quality settings beyond Low.

Settings Recommendations

For 1920x1080, the Medium preset delivers the best experience in the measured data. At 139 FPS average with a minimum of 118, it provides a significant margin above the 60 FPS threshold while still offering better visual quality than Low. The High preset at 98 FPS is also viable, but the 41 FPS cost over Medium buys relatively little visual improvement in a simulation game. Ultra at 93 FPS is acceptable but offers no meaningful advantage over High.

At 2560x1440, Medium is the clear recommendation. The 88 FPS average with a 74 FPS minimum ensures consistent smoothness, while Low at 124 FPS sacrifices visual fidelity for headroom that this game does not require. High at 62 FPS is playable but leaves little margin for demanding scenes, and Ultra at 59 FPS dips below the 60 FPS target.

For 3840x2160, only Low settings are recommended. The 65 FPS average is playable, though not ideal. Medium at 46 FPS and High/Ultra in the low 30s are not suitable for comfortable gameplay. The 4K data suggests that users with 4K displays should either accept Low settings or consider a different GPU pairing.

Overall, the Medium preset at 1440p offers the most balanced experience across the entire dataset. It provides 88 FPS average, stays above 74 FPS minimum, and represents a reasonable middle ground between the Low preset's high frame rates and the diminishing returns of High and Ultra.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, built on TSMC's 5 nm process. It runs at a base clock of 2.50 GHz and boosts up to 5.40 GHz, with 64 MB of L3 cache and 1 MB of L2 cache per core. This mobile processor supports DDR5 memory in dual-channel configuration with 83.2 GB/s bandwidth, and it connects via PCIe Gen 5 with 28 lanes.

In Pc Building Simulator, the CPU's role appears largely supportive rather than performance-limiting. The FPS scaling patterns across resolutions and settings consistently show GPU-bound behavior. The fact that frame rates drop by roughly half from 1080p to 4K at every settings level indicates the RTX 5050 is the constraining component, not the processor.

The CPU's benchmark results confirm its capability. A Cinebench R23 multi-core score of 42713 and single-core score of 6030 place it among the top processors tested. PassMark results further reinforce this: a multi-thread score of 51405, single-thread score of 3907, and physics score of 2168. The processor ranks in the 95th percentile among all CPUs, with an average benchmark score of 76212.

The Ryzen 9 8945HX's nearest rivals in the benchmark database include the Intel Core Ultra 9 285HX, which scores 0.1% higher, and the AMD Ryzen 9 9950X3D, which scores 0.6% higher. The AMD EPYC Embedded 8224P and AMD Ryzen Threadripper PRO 9945WX both score 0.4% lower. This places the CPU in elite company, far above what the RTX 5050's performance tier would typically pair with.

In this game, the CPU's 32 threads and high boost clock ensure that simulation calculations and game logic never become a bottleneck. The 5.40 GHz boost clock provides strong single-threaded performance for any serial tasks, while the 16 cores handle parallel workloads. The data shows that at 1080p Low, the system reaches 196 FPS, which is likely near the game engine's practical limit given the GPU's capabilities. At no point do the measured frame rates suggest CPU limitation, making this processor more than adequate for the title.
