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

The AMD Ryzen 7 7800X3D brings 8 cores and 16 threads to this build, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. This is a Zen 4 architecture part, codenamed Raphael, built on TSMC's 5 nm process node with 11,270 million transistors across a 71 mm² die. The chip's 96 MB of shared L3 cache is the standout feature for gaming workloads, alongside 64 KB of L1 and 1 MB of L2 cache per core. Memory support is DDR5, dual-channel, with 83.2 GB/s of bandwidth, and the CPU includes ECC memory support and Radeon integrated graphics as a fallback.

In synthetic benchmarks, the 7800X3D demonstrates strong multithreaded performance: a Cinebench R23 multicore score of 16817 and a single-core score of 1713. The Geekbench multicore result is 15610, with a single-core score of 2426. PassMark multithread sits at 34293, while single-thread reaches 3759. These numbers place the CPU in the 83rd percentile among all CPUs, with an average benchmark score of 33079.

The nearest rival comparisons are remarkably tight. The AMD Ryzen 7 8700G and Intel Core i7-13650HX both post average scores of 33089, a 0% delta. The AMD Ryzen 7 7745HX matches that 33089 figure again at 0% delta, while the AMD Ryzen 9 PRO 6950H scores 33201, a -0.4% delta — meaning the 7800X3D is essentially neck-and-neck with these parts in aggregate benchmark performance.

For Pc Building Simulator, the data suggests the CPU is not the limiting factor. At 1080p Low, the system reaches 352 FPS, which is far beyond what any game logic would need. Even at 4K Ultra, the CPU's headroom is evident: the bottleneck shifts to the GPU, as shown by the FPS scaling across resolutions (detailed in the Resolution Scaling section). The 8-core, 16-thread configuration is more than sufficient for a simulation title, where the workload is primarily about physics, UI updates, and component state tracking — none of which stress a modern high-end CPU to its limits.

The 3DMark thread scaling scores reinforce this: 2-thread score of 1887, 4-thread of 3684, 8-thread of 6539, and max-thread of 7967. The near-linear scaling from 2 to 8 threads (roughly 3.5x) suggests the game can exploit multiple cores, but the 16-thread result (7967) barely exceeds the 8-thread figure (6539), indicating that Pc Building Simulator likely saturates at around 8 threads — a common pattern for simulation games of this vintage (released January 28, 2019).

Settings Recommendations — which preset gives the best experience per the measured rows

The measured FPS data across all presets provides a clear picture of what this combo can deliver. At 1080p, the Ultra preset averages 168 FPS, while High hits 176 FPS, Medium 249 FPS, and Low 352 FPS. The jump from Ultra to High is only 8 FPS, suggesting diminishing returns at the top end. However, moving to Medium provides a substantial 73 FPS increase over High, with a 81 FPS gain over Ultra.

At 1440p, the pattern holds: Ultra averages 106 FPS, High 111 FPS, Medium 157 FPS, and Low 222 FPS. The Ultra-to-High delta is just 5 FPS, while Medium is 46 FPS ahead of High. At 4K, Ultra yields 55 FPS, High 58 FPS, Medium 82 FPS, and Low 116 FPS. Here, the Ultra-to-High difference is only 3 FPS, but Medium provides a 24 FPS improvement over High.

The data indicates that Medium is the sweet spot for this build. At 1080p Medium, the average of 249 FPS with a minimum of 212 and maximum of 287 FPS ensures smooth gameplay with no perceptible stutter. At 1440p Medium, 157 FPS average (min 134, max 181) maintains high refresh rate compatibility. Even at 4K Medium, 82 FPS average (min 70, max 95) stays above the 60 FPS threshold for comfortable play.

High preset is the conservative choice for visual fidelity. It delivers 176 FPS at 1080p, 111 FPS at 1440p, and 58 FPS at 4K — the latter barely dipping below 60 FPS. Ultra provides only marginal gains over High (8 FPS at 1080p, 5 FPS at 1440p, 3 FPS at 4K), making it the least efficient preset in terms of performance per frame. Low is only useful for maximum FPS testing, as it produces 352 FPS at 1080p, which exceeds the refresh rate of most monitors.

For a balance of visual quality and performance, Medium is recommended. The data shows that the frame time consistency (measured by min-max ranges) is best at Medium: at 1080p, the 75 FPS spread (212-287) is the tightest relative to the average, indicating stable delivery.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The FPS scaling from 1080p to 4K reveals the classic GPU-bound behavior. At Low settings, 1080p delivers 352 FPS, dropping to 222 FPS at 1440p (a 37% reduction) and 116 FPS at 4K (a 67% reduction from 1080p). At Medium, the progression is 249 FPS → 157 FPS → 82 FPS, representing 37% and 67% drops respectively. High settings see 176 FPS → 111 FPS → 58 FPS, with reductions of 37% and 67%. Ultra follows the same pattern: 168 FPS → 106 FPS → 55 FPS, with 37% and 67% drops.

This consistent scaling pattern — roughly 37% loss from 1080p to 1440p, and another 48% loss from 1440p to 4K — is a hallmark of GPU-bound rendering. The CPU's performance is constant across resolutions (it doesn't work harder at higher resolutions), so if the CPU were the bottleneck, FPS would remain flat. Instead, the FPS drops proportionally with pixel count, indicating the NVIDIA GeForce RTX 3080 is the limiting component as resolution increases.

The RTX 3080's capabilities align with this: 10 GB of GDDR6X memory on a 320-bit bus with 760.3 GB/s bandwidth, 8704 shading units, 272 TMUs, and 96 ROPs. The boost clock of 1710 MHz and pixel rate of 164.2 GPixel/s suggest a card designed for high-resolution gaming, but at 4K Ultra, the 55 FPS average shows it's reaching its limits in this title.

The 4K-to-1080p FPS ratio is telling: at Ultra, 4K delivers 55 FPS vs 168 FPS at 1080p, a 3.05x difference. The theoretical pixel count difference is 4x (3840x2160 vs 1920x1080), so the FPS drop is slightly less than pixel scaling would suggest, implying some headroom in the GPU's compute or memory bandwidth at lower resolutions. Conversely, at Low settings, the ratio is 116/352 = 0.33, meaning 4K runs at one-third the speed of 1080p — closer to the 4x pixel count difference, indicating the GPU is fully utilized even at Low settings.

How This Combo Ranks — use comboRankInGame vs other tested combos

This CPU-GPU combination ranks 1022 out of 3723 tested combos for Pc Building Simulator, placing it in the top 27.5% of all configurations tested. This percentile ranking is notable because it suggests that while this is a high-end pairing, the game's modest requirements mean many lower-tier combos achieve similar playable frame rates.

The CPU itself sits at the 83rd percentile among all CPUs, while the GPU is at the 68th percentile among all GPUs. The combo rank of 1022/3723 (72.5th percentile) is lower than either component's individual percentile, indicating that the pairing is somewhat mismatched for this game — the CPU's strength (83rd percentile) is underutilized, while the GPU's 68th percentile is the more relevant factor.

Comparing to the nearest rivals, the CPU's average benchmark score of 33079 is nearly identical to the AMD Ryzen 7 8700G (33089, 0% delta), Intel Core i7-13650HX (33089, 0% delta), and AMD Ryzen 7 7745HX (33091, 0% delta). The AMD Ryzen 9 PRO 6950H edges ahead at 33201 (-0.4% delta). The GPU's average score of 23172 is close to the NVIDIA P106-100 (23249, -0.3% delta), AMD Radeon Pro Vega 16 (23250, -0.3% delta), and AMD Radeon RX 6600M (23273, -0.4% delta).

The implications are clear: swapping the 7800X3D for a cheaper 8700G would yield near-identical CPU performance (0% delta), while swapping the RTX 3080 for an RX 6600M would cost only 0.4% in GPU benchmarks. Yet the measured FPS in this game would likely remain similar, given the simulation's lower demands. The combo rank reflects that many other pairings could deliver comparable frame rates at lower cost, but the data only shows performance — not value — so this analysis stays with what the numbers reveal.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3080 is an Ampere-architecture GPU built on Samsung's 8 nm process, with 28,300 million transistors across a 628 mm² die. The chip, GA102, features 8704 shading units, 272 TMUs, 96 ROPs, 68 RT cores, and 272 tensor cores. The base clock is 1440 MHz, boosting to 1710 MHz, with memory running at 1188 MHz (19 Gbps effective). The 10 GB of GDDR6X memory on a 320-bit bus provides 760.3 GB/s of bandwidth. Compute performance is rated at 29.77 TFLOPS for both FP32 and FP16.

The GPU's benchmark results show a 3DMark Steel Nomad DX12 score of 4407, Geekbench OpenCL score of 152423, and Vulkan score of 33620. PassMark G3D scores 25086, with GPU compute at 14397. The card sits in the 68th percentile among all GPUs, with an average benchmark score of 23172.

In Pc Building Simulator, the RTX 3080's role is clearly visible in the resolution scaling. At 1080p, the GPU has headroom — even at Ultra, 168 FPS leaves performance on the table. At 4K, the card is fully utilized, with Ultra dropping to 55 FPS. The 10 GB VRAM is not a constraint in this title, as simulation games typically have modest texture requirements, but the 760.3 GB/s bandwidth and 164.2 GPixel/s pixel rate determine how quickly the renderer can fill frames.

The memory clock of 1188 MHz (19 Gbps effective) combined with the 320-bit bus yields the 760.3 GB/s figure, which is crucial at 4K where memory bandwidth becomes a bottleneck. The data shows that at 4K, the FPS drops are more pronounced (67% loss from 1080p), consistent with the GPU's memory system being the limiting factor at higher resolutions.

The passmark DirectX scores (DX9: 258, DX10: 170, DX11: 207, DX12: 100) provide context — the DX12 score is lowest, but this game, released in 2019, likely uses an older API path. The RTX 3080's support for DirectX 12 Ultimate (12_2) is forward-looking, but the game's engine may not fully leverage it.
