# Pc Building Simulator Performance Analysis: Core Ultra 7 265HX + RTX 5080

The Intel Core Ultra 7 265HX paired with the NVIDIA GeForce RTX 5080 delivers a remarkably consistent experience across Pc Building Simulator, with the data showing a combination that scales predictably from 1080p to 4K. The measured frame rates reveal that this pairing is heavily GPU-bound at higher resolutions, while at 1080p the CPU's 20 cores and 5.30 GHz boost clock keep the pipeline fed without bottlenecking. This combo ranks 725th out of 3002 tested configurations, placing it in the top quarter of all tested combinations despite the game's modest visual demands.

Resolution Scaling

The resolution scaling pattern in Pc Building Simulator is textbook GPU-bound behavior, but with some notable nuances at the extremes. Moving from 1920x1080 to 2560x1440 at Ultra settings, the average frame rate drops from 172 FPS to 109 FPS, a 36.6% reduction. The 1440p to 4K transition at Ultra is steeper, falling from 109 FPS to 57 FPS, a 47.7% decline. This accelerating drop-off as resolution increases confirms that the RTX 5080's rendering throughput becomes the limiting factor at 4K.

At Low settings, the scaling pattern tells a different story. The 1080p Low result of 362 FPS drops to 228 FPS at 1440p (37% reduction) and then to 119 FPS at 4K (47.8% reduction). The fact that even at Low settings 4K performance falls below 120 FPS suggests that pixel throughput, not shader complexity, is the primary constraint. The RTX 5080's 960.0 GB/s memory bandwidth and 56.28 TFLOPS FP32 compute are being exercised heavily at 3840x2160 regardless of settings.

The Medium preset shows the most complete data, with minimum and maximum frame rates recorded. At 1080p Medium, the average of 256 FPS spans a range from 218 to 295 FPS, a 77 FPS spread. At 1440p Medium, the 162 FPS average spans 137 to 186 FPS, a 49 FPS spread. At 4K Medium, the 85 FPS average spans 72 to 97 FPS, a 25 FPS spread. This narrowing variance at higher resolutions is characteristic of GPU-bound scenarios where frame time consistency improves as the CPU has more headroom relative to GPU workload.

Comparing High to Ultra at each resolution reveals the cost of the highest preset. At 1080p, High delivers 181 FPS while Ultra delivers 172 FPS, a modest 5% penalty. At 1440p, the gap is 114 FPS versus 109 FPS, a 4.4% penalty. At 4K, High achieves 60 FPS exactly, while Ultra falls to 57 FPS, a 5% penalty. The consistency of this penalty across resolutions suggests that the Ultra preset adds a relatively uniform workload increase rather than a resolution-dependent effect.

Settings Recommendations

For players targeting 60 FPS as a baseline, the data shows that 4K High is the minimum viable preset, delivering exactly 60 FPS on average. However, the lack of minimum frame rate data for High settings at 4K means there is inherent uncertainty about frame time consistency. The Medium preset at 4K provides more confidence with a 72 FPS minimum and 85 FPS average, making it the safer choice for 4K gaming despite the visual downgrade from High.

At 2560x1440, the High preset delivers 114 FPS average, which comfortably exceeds 100 FPS for smooth gameplay. The Ultra preset at 1440p still manages 109 FPS, making it the recommended choice for players with 144Hz displays who want maximum visual quality. The jump from Medium to Ultra at 1440p costs only 53 FPS (162 down to 109), which is a reasonable trade for the visual improvements.

For 1080p, the Ultra preset at 172 FPS is the clear recommendation for high-refresh-rate displays up to 170Hz. Players with 240Hz displays should consider High at 181 FPS, though the Low preset at 362 FPS is the only option that fully saturates a 360Hz panel. The Medium preset's 256 FPS average with a 218 FPS minimum makes it viable for 240Hz displays with some headroom for frame time spikes.

The data suggests that the Low preset is rarely the optimal choice given the hardware's capabilities. At every resolution, the gap between Low and Medium is substantial (119 to 85 FPS at 4K, 228 to 162 FPS at 1440p, 362 to 256 FPS at 1080p), but the visual quality trade-off is rarely worth it when Medium or High maintain playable frame rates at all resolutions.

How This Combo Ranks

With a rank of 725 out of 3002 tested combinations, this Intel Core Ultra 7 265HX and RTX 5080 pairing sits comfortably in the upper quartile of all tested configurations for Pc Building Simulator. This ranking is particularly noteworthy given the CPU's mobile market segment and 55 W TDP, which might suggest lower performance headroom than desktop parts. However, the benchmark data shows the CPU competing effectively, with a 93rd percentile ranking against all CPUs and an average benchmark score of 63173.

The CPU's nearest rivals in the overall benchmark hierarchy include the Intel Core i7-13790F with an average score of 63080 (0.1% behind), the AMD Ryzen AI 7 450G at 63331 (0.2% ahead), and the AMD Ryzen AI Embedded P185 at 62839 (0.5% behind). The Intel Core Ultra 7 255HX trails by 0.7% with a score of 62738. These tight margins indicate that the 265HX is positioned within a competitive cluster of processors rather than dominating its segment.

For the GPU, the RTX 5080's 87th percentile ranking among all GPUs and average benchmark score of 56083 places it ahead of the AMD Radeon 8060S (55757, 0.6% behind) and the AMD Radeon RX 6750 GRE 12 GB (55698, 0.7% behind). The AMD Radeon Pro W5700X at 54828 trails by 2.3%, while the AMD Radeon RX 9070 GRE at 57367 leads by 2.2%. This positioning suggests the RTX 5080 is a strong but not dominant performer in its peer group.

The game-specific ranking of 725 out of 3002 combos (approximately the 76th percentile) is lower than both component percentile rankings might suggest, indicating that Pc Building Simulator's workload characteristics do not fully utilize the strengths of this particular pairing. The simulation genre's typically modest graphical demands mean that the RTX 5080's substantial compute resources are only partially exercised at lower resolutions.

CPU Role

The Intel Core Ultra 7 265HX brings 20 cores and 20 threads to this configuration, operating with a base clock of 2.60 GHz and a boost clock of 5.30 GHz. This Arrow Lake-HX architecture, built on TSMC's 3 nm process, features 30 MB of shared L3 cache and per-core L2 cache of 3 MB. The CPU's benchmark results demonstrate strong multi-threaded performance, with a Cinebench R23 multi-core score of 40642 and a single-core score of 5737.

In Pc Building Simulator, the CPU's role appears primarily focused on maintaining high frame rates at lower resolutions where GPU load is less demanding. The 1080p Low result of 362 FPS is particularly telling, as this scenario would expose CPU limitations if they existed. The processor's 47985 Passmark multi-thread score and 4500 single-thread score suggest it has ample headroom for the game's simulation logic, which typically involves managing component inventories, compatibility checks, and system building mechanics.

The CPU's 93rd percentile ranking among all processors, with an average benchmark score of 63173, places it in the top tier of available CPUs. Its nearest rivals in benchmark performance are separated by less than 1%, indicating that the 265HX is not an outlier but rather a solid mid-high performer. The Passmark physics score of 2978 and floating point math score of 161605 indicate strong computational throughput, though these are unlikely to be fully utilized by Pc Building Simulator's relatively straightforward simulation demands.

The 17,800 million transistors packed into a 243 mm² die with a 3 nm process node give the 265HX a significant efficiency advantage, though TDP data shows a 55 W envelope that is modest for a 20-core processor. The dual-channel DDR5 memory support with 102.4 GB/s bandwidth provides sufficient memory throughput for the game's data access patterns, and the integrated Arc Xe-LPG Graphics 64EU offers a fallback display option, though the discrete RTX 5080 handles all rendering duties in this configuration.

Measured FPS Breakdown

At 1920x1080, the measured results show exceptional performance across all presets. The Low preset leads with 362 FPS average, followed by Medium at 256 FPS (with 218 FPS minimum and 295 FPS maximum), High at 181 FPS, and Ultra at 172 FPS. The progression from Low to Ultra shows a 52.5% reduction in frame rate, reflecting the increasing graphical workload at this resolution where the CPU has significant headroom.

The 2560x1440 results demonstrate the expected performance scaling. Low delivers 228 FPS, Medium provides 162 FPS (137 minimum, 186 maximum), High achieves 114 FPS, and Ultra reaches 109 FPS. The gap between Medium and High is 48 FPS, while the gap between High and Ultra narrows to just 5 FPS, indicating diminishing returns from the highest preset at this resolution.

At 3840x2160, the performance envelope tightens considerably. Low manages 119 FPS, Medium delivers 85 FPS (72 minimum, 97 maximum), High achieves exactly 60 FPS, and Ultra falls to 57 FPS. The 4K Low result of 119 FPS is notable as it shows the RTX 5080 can exceed 100 FPS at 4K when graphical settings are minimized, but the progression to higher presets quickly brings performance down to console-like levels.

The Medium preset is the only one with complete minimum and maximum data across all three resolutions, providing the most detailed picture of frame time behavior. At 1080p, the 218-295 FPS range represents a 35.3% spread relative to the 256 FPS average. At 1440p, the 137-186 FPS range represents a 35.8% spread. At 4K, the 72-97 FPS range represents a 29.4% spread. The slightly tighter percentage spread at 4K suggests more consistent frame pacing when the GPU is the primary bottleneck.

The overall pattern across all measured results shows a clear hierarchy: resolution scaling has the largest impact on performance, followed by preset selection. The RTX 5080's 16 GB of GDDR7 memory on a 256-bit bus with 960.0 GB/s bandwidth provides ample capacity and throughput for 4K textures, while the GPU's 10752 shading units and 112 ROPs handle the pixel workload efficiently. The 293.1 GPixel/s pixel rate and 879.3 GTexel/s texture rate are the specifications most relevant to the game's 2D-heavy interface and component visualization workloads.
