The NVIDIA GeForce RTX 5080 pairs 16 GB of GDDR7 memory on a 256-bit bus with 960.0 GB/s of bandwidth. The GPU operates at a base clock of 2295 MHz and boosts to 2617 MHz, with the memory running at 1875 MHz (30 Gbps effective). The Blackwell 2.0 architecture provides 10752 shading units, 336 texture mapping units, and 112 render output units, along with 84 RT cores and 336 tensor cores.

The GPU's benchmark results show strong compute performance, with a 3DMark Steel Nomad DX12 score of 8637 and a Geekbench OpenCL score of 235901. The Vulkan score of 255450 is notably higher, indicating good API efficiency. In PassMark tests, the GPU scores 36565 in G3D and 21789 in compute tests. These results place the RTX 5080 at the 87th percentile among all GPUs, with an average benchmark score of 56083.

For Pc Building Simulator, the GPU's role is to render the 3D scenes of computer components and the assembly workspace. The game does not appear to be graphically intensive, as evidenced by the high frame rates achieved even at 4K resolution. The GPU's 16 GB of VRAM is more than sufficient for this title, and the high memory bandwidth of 960.0 GB/s ensures that texture streaming is not a bottleneck.

The GPU's performance relative to its nearest rivals shows a competitive position. The 0.6% lead over the Radeon 8060S and 0.7% lead over the RX 6750 GRE 12 GB indicate that the RTX 5080 is slightly ahead of these alternatives. The 2.3% lead over the Radeon Pro W5700X is more substantial, while the 2.2% deficit to the Radeon RX 9070 GRE shows that there is a faster option in this segment. However, for Pc Building Simulator specifically, these differences may not translate into noticeable frame rate advantages given the game's modest GPU requirements.

Settings Recommendations

Based on the measured frame rate data, the Ultra preset provides the most visually complete experience while maintaining playable performance at all resolutions. At 1080p Ultra, the combo delivers 172 FPS average, which is well above the threshold for smooth gameplay. At 1440p Ultra, 109 FPS average remains highly fluid, and even at 4K Ultra, the 57 FPS average is sufficient for a simulation game where precise timing is not critical.

However, the Medium preset offers the most balanced experience across the board. At 1080p Medium, the 256 FPS average provides a significant margin over the refresh rate of most displays, and the minimum of 218 FPS ensures no noticeable stuttering. At 1440p Medium, 162 FPS average with a minimum of 137 FPS keeps the experience consistently smooth. At 4K Medium, 85 FPS average with a minimum of 72 FPS remains well within the v-sync range for 60 Hz displays.

For users with 4K displays, the High preset at 60 FPS average is the recommended choice if visual fidelity is prioritized over raw frame rate. The Low preset at 119 FPS average at 4K may be preferable for those seeking maximum smoothness, but the visual compromise is likely unnecessary given the game's nature. The data shows that the combo is never below 57 FPS at any resolution and setting combination, meaning all presets are technically playable.

The most efficient configuration appears to be 1440p High, which delivers 114 FPS average while providing better visual quality than Medium. The jump from Medium to High at 1440p costs 48 FPS (162 to 114), while the jump from High to Ultra costs only 5 FPS (114 to 109). This suggests that the High preset at 1440p captures most of the visual benefit of Ultra without the performance penalty.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals important information about the limiting component in this system. At Low settings, the average FPS drops from 362 at 1080p to 228 at 1440p and 119 at 4K. This represents a 37% reduction from 1080p to 1440p and a 67.1% reduction from 1080p to 4K. The scaling is roughly proportional to the pixel count increase, suggesting GPU-bound behavior at low settings.

At Medium settings, the scaling shows a similar pattern: 256 FPS at 1080p, 162 FPS at 1440p, and 85 FPS at 4K. The reduction from 1080p to 1440p is 36.7%, and from 1080p to 4K is 66.8%. The consistency of these percentages across Low and Medium settings indicates that the GPU is the primary limiting factor at these settings, as the CPU has sufficient headroom to maintain frame delivery.

At High settings, the scaling is slightly different: 181 FPS at 1080p, 114 FPS at 1440p, and 60 FPS at 4K. The reduction from 1080p to 1440p is 37%, and from 1080p to 4K is 66.9%. At Ultra settings, 172 FPS at 1080p, 109 FPS at 1440p, and 57 FPS at 4K show reductions of 36.6% and 66.9% respectively. The remarkably consistent scaling percentages across all settings suggest that the GPU is the dominant limiting component throughout the resolution range.

The consistent ~37% drop from 1080p to 1440p and ~67% drop from 1080p to 4K aligns closely with the pixel count scaling (1440p has 1.78x the pixels of 1080p, 4K has 4x). This near-linear scaling indicates that the system is GPU-bound at all tested settings and resolutions, with the CPU providing adequate support even at the highest frame rates. The RTX 5080's performance characteristics, including its 960.0 GB/s memory bandwidth and 56.28 TFLOPS FP32 throughput, are the determining factors in this game's performance envelope.
