Pc Building Simulator

# CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 9700X is an 8-core, 16-thread processor based on the Zen 5 architecture (Granite Ridge), built on TSMC's 4 nm process. It operates with a base clock of 3.80 GHz and a boost clock of 5.50 GHz, with a 65 W TDP. The CPU's cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. It supports DDR5 memory via a dual-channel bus with 89.6 GB/s of memory bandwidth, and it connects through PCIe Gen 5 with 24 lanes.

In Pc Building Simulator, the CPU's role is primarily to manage the simulation logic, component compatibility checks, and system boot sequences, which are largely single-threaded tasks. The 9700X's single-thread performance is strong, as evidenced by a 3dmark_single_thread score of 1280 and a Geekbench single-core score of 3353. These scores indicate that the processor can handle the game's frequent, short-duration calculations without becoming a bottleneck.

However, the game also benefits from multi-threaded performance during complex builds with many components. The 9700X posts a 3dmark_16_threads score of 9824 and a 3dmark_max_threads score of 9771, showing that its 16 threads scale effectively. Cinebench R23 multicore score of 31588 and Geekbench multicore score of 17002 confirm that the CPU can handle heavy simulation workloads when needed.

The CPU's 89th percentile ranking versus all CPUs places it above the vast majority of processors. Its nearest rivals in average benchmark score include the Intel Core i5-14500HX (0.2% faster), AMD Ryzen 7 PRO 5845 (0.6% faster), Intel Core Ultra 9 185H (0.4% slower), and Intel Core Ultra 5 225H (0.8% slower). These margins are tiny, indicating that the 9700X is right at the top of its performance tier, with no single rival holding a decisive advantage.

For Pc Building Simulator specifically, the data shows that the CPU is more than sufficient. The game is not known for pushing CPUs to their limits, and the 9700X's combination of high single-thread and multi-thread scores ensures that it will not be the limiting factor in any of the measured configurations.

How This Combo Ranks

The combination of the AMD Ryzen 7 9700X and NVIDIA GeForce RTX 5080 achieves a combo rank of 34 out of 1769 tested combinations in Pc Building Simulator. This places the pairing in the top 1.9% of all tested combos, indicating that it is among the most powerful configurations available for this game.

This high ranking is expected given the individual strengths of both components. The CPU sits in the 89th percentile of all processors, and the GPU also sits in the 89th percentile of all graphics cards. When paired together, they create a balanced system with no obvious weak link.

The rank of 34 suggests that only 33 other combinations outperform this pairing in Pc Building Simulator. Those higher-ranked combos likely feature even more powerful CPUs or GPUs, but the margin between them and the 9700X + RTX 5080 pairing is likely small. The data indicates that this combo delivers near-top-tier performance, suitable for the most demanding simulation tasks the game can throw at it.

Given that Pc Building Simulator is a simulation title rather than a fast-paced shooter, the absolute performance ceiling is less critical than consistency and stability. The combo's high rank confirms that it delivers smooth, reliable frame rates across all tested scenarios.

Resolution Scaling

The measured FPS data reveals how the system scales across three resolutions: 1920x1080, 2560x1440, and 3840x2160. At Low settings, the average FPS drops from 469.9 at 1080p to 311.7 at 1440p (a 33.7% reduction), and then to 162.4 at 4K (a 47.9% reduction from 1440p). This steep drop from 1440p to 4K at Low settings indicates that even at minimal graphical load, the GPU is becoming the primary limiter at higher resolutions.

At Medium settings, the progression is from 355.1 FPS at 1080p, to 222.8 at 1440p (a 37.3% drop), and then to 118.9 at 4K (a 46.6% drop from 1440p). The pattern is similar, with the largest percentage decline occurring between 1440p and 4K.

High settings show 250.4 FPS at 1080p, 156.7 at 1440p (a 37.4% drop), and 81.2 at 4K (a 48.2% drop from 1440p). Ultra settings follow the same trend: 234.5 FPS at 1080p, 148.2 at 1440p (a 36.8% drop), and 81.1 at 4K (a 45.3% drop from 1440p).

The consistent 35-37% drop from 1080p to 1440p across all settings suggests that the CPU is still contributing at 1440p, but the larger 45-48% drop from 1440p to 4K points to the GPU becoming the dominant constraint. At 4K, the pixel count quadruples compared to 1080p, and the RTX 5080's rendering capabilities determine the final frame rate.

The difference between High and Ultra settings at 4K is minimal (81.2 vs 81.1 FPS), indicating that the game's Ultra preset adds little extra load at that resolution. This suggests that at 4K, the system is hitting a performance ceiling that is largely independent of settings beyond a certain point.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all settings. Low settings produce an average of 469.9 FPS, Medium reaches 355.1 FPS, High achieves 250.4 FPS, and Ultra maintains 234.5 FPS. These numbers are far above any practical refresh rate, meaning the system is heavily CPU-limited at this resolution, particularly at Low and Medium settings where the GPU is underutilized.

Moving to 2560x1440, the performance remains very high. Low settings average 311.7 FPS, Medium hits 222.8 FPS, High reaches 156.7 FPS, and Ultra dips to 148.2 FPS. The gap between High and Ultra narrows to just 5.4%, suggesting that the Ultra preset's additional effects have diminishing returns at this resolution.

At 3840x2160, the system still delivers playable frame rates. Low settings average 162.4 FPS, Medium reaches 118.9 FPS, High achieves 81.2 FPS, and Ultra produces 81.1 FPS. The near-identical results for High and Ultra at 4K indicate that the GPU is saturated, and the extra settings have minimal impact on performance.

The data shows a clear pattern: at 1080p, the CPU is the limiting factor, as evidenced by the wide gap between Low (469.9 FPS) and Ultra (234.5 FPS) — a 50.1% difference. At 4K, the GPU takes over, with the gap between Low and Ultra shrinking to 50.1% as well (162.4 vs 81.1 FPS), but for the opposite reason: the GPU is fully utilized even at Low settings.

GPU Role

The NVIDIA GeForce RTX 5080 is built on the Blackwell 2.0 architecture (chip GB203) using TSMC's 5 nm process. It features 10,752 shading units, 336 texture mapping units, and 112 raster output units, along with 84 RT cores and 336 tensor cores. The GPU operates at a base clock of 2295 MHz and a boost clock of 2617 MHz, with memory clocked at 1875 MHz (30 Gbps effective).

The 16 GB of GDDR7 memory on a 256-bit bus provides 960.0 GB/s of bandwidth. This is substantial for a simulation game that may load many textures and models. The GPU's compute capabilities are strong, with FP32 performance of 56.28 TFLOPS and a pixel rate of 293.1 GPixel/s.

In Pc Building Simulator, the GPU's role is to render the 3D workspace, component models, and any visual effects. The game's graphics are not particularly demanding compared to AAA titles, but the RTX 5080's raw power ensures that even at 4K Ultra, the system maintains 81.1 FPS.

The GPU's benchmark scores reflect its high-tier position. It achieves a 3dmark_steel_nomad_dx12 score of 8637, a Geekbench OpenCL score of 264461, and a Geekbench Vulkan score of 257942. The Passmark G3D score of 36565 places it in the 89th percentile of all GPUs.

Its nearest rivals in average benchmark score include the Intel Arc A570M (1.6% faster), Intel Arc Pro A60 (1.9% slower), Intel Arc A580 (2.5% faster), and AMD Radeon Pro W5500X (2.6% faster). These margins are small, showing that the RTX 5080 is competitive with other high-end graphics cards, though not universally dominant.

The GPU's 360 W TDP and suggested 750 W PSU indicate that it requires substantial power, but the dual-slot design and PCIe 5.0 x16 interface ensure it can be integrated into most modern systems. The 16 GB VRAM is more than sufficient for this game, even at 4K Ultra settings.
