Pc Building Simulator

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

The AMD Ryzen 7 3700X is an 8-core, 16-thread processor built on the Zen 2 architecture, codenamed Matisse. It operates from a base clock of 3.60 GHz up to a boost clock of 4.40 GHz, with a 65 W TDP. This 7 nm part from TSMC is paired with a 32 MB L3 cache and supports dual-channel DDR4 memory. For a simulation title, the 8-core configuration is relevant because the genre typically involves physics calculations, object tracking, and system state updates that scale with core count. The processor's multi-core capability is reflected in benchmarks such as a Cinebench R23 multi-core score of 19087, while its single-core score of 2694 indicates modest per-thread strength.

In the context of Pc Building Simulator, the CPU's role is less about raw graphical output and more about maintaining consistent frame pacing during complex system-building interactions. The data shows that at 1080p with Low settings, the combo reaches 264.7 FPS, which suggests the CPU is not a bottleneck at lower resolutions when the GPU has less work. However, as resolution increases, the CPU's influence diminishes relative to the GPU. The Ryzen 7 3700X's 16 threads provide ample parallelism for a game that simulates hardware behavior, though the single-thread performance is only slightly ahead of rivals — the Intel Core i5-12600 scores -0.1% lower in average benchmark score, while the AMD Ryzen 5 5600XT is 0.1% higher. This tight grouping indicates that for this game's CPU-bound scenarios, the 3700X is competitive but not dominant.

How This Combo Ranks

The combination of the AMD Ryzen 7 3700X and NVIDIA GeForce RTX 3080 achieves a rank of 618 out of 1769 tested combos in Pc Building Simulator. This places it in the upper-middle tier of configurations, which is notable given the GPU's strength. The percentile data shows the CPU is in the 85th percentile versus all CPUs, and the GPU is in the 80th percentile versus all GPUs, yet their combined ranking is not proportionally higher. This suggests that the game's performance is not purely additive — the CPU's mid-pack single-thread performance may limit the GPU's potential in certain scenarios.

The ranking gap becomes clearer when examining the nearest rivals. The CPU's average benchmark score of 28631 is nearly identical to the Intel Core i5-12600 (28654, -0.1%) and the Intel Core i5-12600H (28666, -0.1%). The AMD Ryzen 5 5600XT is marginally ahead at 28591 (0.1%), and the AMD EPYC 7203P is slightly further at 28583 (0.2%). These differences are within statistical noise, meaning the 3700X is effectively tied with these processors in synthetic benchmarks. For the GPU, the RTX 3080's average benchmark score of 35787 is 0.2% behind the AMD Radeon Pro Duo (35860) and 0.9% behind the AMD Radeon RX 7900 GRE (36101), while being 0.4% ahead of the AMD Radeon 880M (35646) and 1% ahead of the NVIDIA GeForce RTX 5070 Ti Mobile (35435). The combo's rank of 618 out of 1769 indicates that while each component is strong individually, the pairing does not boost the system into the top tier for this specific simulation game, likely due to the game's moderate CPU demands that do not fully utilize the 16-thread capability.

Resolution Scaling

The FPS data from 1080p to 4K reveals a clear pattern of GPU-bound scaling. At 1080p High settings, the combo achieves 176.5 FPS, which drops to 112.8 FPS at 1440p (a reduction of 36%) and further to 55.4 FPS at 4K (a reduction of 69% from 1080p). This steep decline indicates that the RTX 3080 is the limiting component at higher resolutions, as the CPU's performance headroom is sufficient at lower pixel counts. The same trend appears at Ultra settings: 165.3 FPS at 1080p, 105.3 FPS at 1440p, and 55.5 FPS at 4K. The 4K Ultra score is nearly identical to the 4K High score (55.5 vs 55.4), suggesting that at 4K, the GPU is saturated regardless of whether High or Ultra settings are used.

At Low settings, the scaling is even more pronounced, indicating CPU involvement. At 1080p Low, the combo reaches 264.7 FPS, which drops to 222.2 FPS at 1440p (a 16% reduction) and 118.6 FPS at 4K (a 55% reduction). The smaller drop from 1080p to 1440p at Low settings compared to High settings suggests that the CPU is holding back performance at lower resolutions — the 8-core, 16-thread processor can only push so many frames, even when the GPU has minimal work. At 4K Low, the FPS more than doubles the 4K High score (118.6 vs 55.4), indicating that the game's graphical settings have a significant impact on GPU load, while the CPU remains the limiting factor only at the lowest resolution and settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce 264.7 FPS, Medium settings 233.1 FPS, High settings 176.5 FPS, and Ultra settings 165.3 FPS. The gap between Low and Ultra is 60%, showing that settings have a substantial impact on GPU workload even at 1080p. The difference between High and Ultra is only 6.3%, indicating diminishing returns at the highest quality preset.

At 2560x1440, the scores moderate significantly. Low settings yield 222.2 FPS, Medium settings 160 FPS, High settings 112.8 FPS, and Ultra settings 105.3 FPS. The drop from 1080p to 1440p is largest at High settings (36% reduction), while Low settings see a smaller 16% reduction. This suggests that the CPU can still feed the GPU at 1440p Low, but as settings increase, the GPU becomes the bottleneck, causing a steeper FPS decline.

At 3840x2160, the performance is heavily GPU-limited. Low settings produce 118.6 FPS, Medium settings 82.8 FPS, High settings 55.4 FPS, and Ultra settings 55.5 FPS. The striking similarity between High and Ultra at 4K (55.4 vs 55.5 FPS) indicates that the RTX 3080's 10 GB GDDR6X memory and 760.3 GB/s bandwidth are maxed out, regardless of whether High or Ultra is selected. The Medium setting at 82.8 FPS shows a 33% improvement over High, but still represents a significant drop from 1440p Medium (160 FPS). Overall, the data shows a consistent pattern: the RTX 3080 provides excellent performance at 1080p and 1440p, but 4K gaming requires either Low or Medium settings to maintain playable frame rates above 60 FPS.

GPU Role

The NVIDIA GeForce RTX 3080 is built on the Ampere architecture with the GA102 chip, manufactured on Samsung's 8 nm process. It features 8704 shading units, 272 texture mapping units, and 96 raster output units, along with 68 RT cores and 272 tensor cores. The GPU operates at a base clock of 1440 MHz with a boost clock of 1710 MHz, and its 10 GB of GDDR6X memory runs at an effective speed of 19 Gbps across a 320-bit bus, delivering 760.3 GB/s of bandwidth. This memory configuration is a key factor in the 4K performance observed — the 10 GB capacity is sufficient for most games at High settings, but the similar 4K High and Ultra scores suggest that memory bandwidth, not capacity, is the limiting factor at that resolution.

The RTX 3080's compute capabilities include 29.77 TFLOPS of FP32 performance, a texture rate of 465.1 GTexel/s, and a pixel rate of 164.2 GPixel/s. These specifications directly influence the measured FPS in Pc Building Simulator. At 1080p Ultra, the GPU produces 165.3 FPS, which drops to 105.3 FPS at 1440p and 55.5 FPS at 4K. The near-linear scaling with pixel count (1080p to 1440p is a 1.78x pixel increase, and FPS drops by 36%; 1440p to 4K is a 2.25x increase, and FPS drops by 47%) indicates the GPU is the primary performance limiter at higher resolutions. The GPU's 80th percentile ranking versus all GPUs, with an average benchmark score of 35787, places it slightly below the AMD Radeon RX 7900 GRE (36101, -0.9%) but above the AMD Radeon 880M (35646, 0.4%). In this simulation game, the RTX 3080 demonstrates strong 1080p and 1440p performance, while 4K requires settings tuning to stay above 60 FPS, with Low settings providing 118.6 FPS and Medium providing 82.8 FPS.
