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

The AMD Ryzen 5 7600 is a 6-core, 12-thread processor built on the Zen 4 architecture, codenamed Raphael, and fabricated on a 5 nm process by TSMC. Its base clock is 3.80 GHz with a boost clock of 5.10 GHz, and it carries a 65 W TDP. The chip includes 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. Memory support is DDR5 over a dual-channel bus with 83.2 GB/s of bandwidth, and the CPU supports ECC memory. The 7600 integrates Radeon Graphics and connects via PCIe Gen 5 with 24 lanes from the CPU.

In synthetic CPU benchmarks, the Ryzen 5 7600 scores 999 in 3DMark single-thread and 6,503 in 3DMark max-threads. Cinebench R23 results show 1,852 single-core and 12,735 multi-core. Geekbench reports 2,521 single-core and 13,413 multi-core. PassMark multithread is 27,058, while PassMark single-thread is 3,910. The average benchmark score across all tests is 26,324, placing it in the 78th percentile of all CPUs.

For a simulation game like Pc Building Simulator, the data suggests the CPU's high single-thread performance is relevant. The boost clock of 5.10 GHz and strong single-core scores (999 in 3DMark single-thread, 1,852 in Cinebench R23) indicate that the CPU can handle the simulation logic and UI interactions that often rely on single-threaded tasks. The multi-thread capacity, with 12 threads and a 12,735 Cinebench R23 multi-core score, supports background processes and any parallelized simulation workloads, though the game's measured FPS patterns show the GPU becomes the primary bottleneck at higher resolutions.

Compared to its nearest rivals, the Ryzen 5 7600 sits very close in average benchmark score. The AMD Ryzen 9 6900HX has an average score of 26,274, just 0.2% behind. The AMD Ryzen 7 7435HS scores 26,402, 0.3% ahead. The Intel Core i9-11900KF scores 26,212, 0.4% behind, and the AMD Ryzen 5 8540U scores 26,187, 0.5% behind. These deltas are within noise, meaning the CPU's performance class is comparable to those parts, though the 7600's specific combination of 6 cores, 12 threads, and 5.10 GHz boost is what matters for this game.

How This Combo Ranks

The combination of the AMD Ryzen 5 7600 and the AMD Radeon RX 5700 XT ranks 2,769 out of 3,723 tested combos in Pc Building Simulator. This places the combo in the lower-mid range of all tested configurations, meaning roughly 74% of tested combos perform better in this game. The rank is driven by the GPU's age and performance tier rather than the CPU, as the CPU's percentile (78th) is far higher than the GPU's percentile (59th).

The data indicates that the CPU is not the limiting factor in this pairing. The Ryzen 5 7600's 78th percentile standing among all CPUs is strong, but the RX 5700 XT's 59th percentile among all GPUs drags the overall combo rank down. In Pc Building Simulator, which is a simulation title with moderate graphical demands, the GPU's raw throughput and memory bandwidth dictate frame rates more than the CPU's core count or clock speed.

The gap between the combo's rank (2,769 of 3,723) and the CPU's individual percentile (78) highlights this imbalance. If the CPU were the bottleneck, the combo rank would be closer to the CPU's percentile. Instead, the combo rank is lower, suggesting that the RX 5700 XT is the constraining component. For context, the CPU's nearest rivals all have average benchmark scores within 0.5% of the 7600, so swapping the CPU for a Ryzen 9 6900HX or Core i9-11900KF would not meaningfully change the combo's rank in this game, as the GPU would still limit performance.

Resolution Scaling

The measured FPS data shows a clear pattern of performance scaling across resolutions. At 1080p with Low settings, the combo achieves 220 FPS. Moving to 1440p Low drops this to 139 FPS, a 37% reduction. At 4K Low, the FPS falls to 72, another 48% drop from 1440p. This steep decline indicates that the GPU is increasingly stressed as pixel count rises, with the CPU having ample headroom at lower resolutions.

At Medium settings, the scaling is similar but with lower absolute numbers. The 1080p Medium average is 156 FPS, 1440p Medium is 98 FPS (a 37% drop), and 4K Medium is 51 FPS (a 48% drop from 1440p). The consistency of these percentage drops across settings suggests that the resolution scaling is primarily a GPU-bound effect, not a CPU or settings-driven phenomenon.

For High settings, the pattern holds: 1080p High is 110 FPS, 1440p High is 69 FPS (a 37% drop), and 4K High is 36 FPS (a 48% drop from 1440p). Ultra settings show 105 FPS at 1080p, 66 FPS at 1440p (a 37% drop), and 35 FPS at 4K (a 47% drop from 1440p). The uniform ~37% drop from 1080p to 1440p and ~48% drop from 1440p to 4K across all settings is a signature of a GPU-limited scenario. The CPU's performance headroom is sufficient to maintain the same relative scaling regardless of graphical load.

The limiting component is clearly the GPU. At 1080p Low, the 220 FPS result shows the CPU can drive very high frame rates, but the GPU cannot sustain that at higher resolutions. The RX 5700 XT's 8 GB of GDDR6 memory and 448.0 GB/s bandwidth are likely the constraints, as the game's asset loading and rendering at 4K exceed what the GPU can process quickly. The data shows no scenario where the CPU causes a disproportionate FPS drop; the scaling is smooth and predictable, pointing to the GPU as the bottleneck.

Measured FPS Breakdown

At 1920x1080, the measured average FPS ranges from 105 to 220 depending on settings. Low settings yield 220 FPS, Medium drops to 156 FPS (with a min of 132 and max of 179), High yields 110 FPS, and Ultra produces 105 FPS. The difference between High and Ultra at 1080p is only 5 FPS, suggesting diminishing returns from the highest preset. The min FPS data is only available for Medium (132 FPS), which represents a 15% dip below the average, indicating some frame time variance but no severe stutter.

At 2560x1440, the average FPS spans 66 to 139. Low settings give 139 FPS, Medium provides 98 FPS (min 84, max 113), High offers 69 FPS, and Ultra drops to 66 FPS. The gap between High and Ultra at 1440p is just 3 FPS, again showing that Ultra provides marginal gains over High. The Medium preset's min FPS of 84 is 14% below its average, slightly worse relative variance than at 1080p.

At 3840x2160, the averages fall to 35 to 72 FPS. Low settings reach 72 FPS, Medium averages 51 FPS (min 44, max 59), High averages 36 FPS, and Ultra averages 35 FPS. High and Ultra are nearly identical at 4K, with only 1 FPS separating them. The Medium preset's min FPS of 44 is 14% below its average, consistent with the 1440p pattern. The 4K Low result of 72 FPS is notable because it is close to the 1440p High result of 69 FPS, meaning the user can trade resolution against settings to achieve similar performance.

Across all resolutions, the FPS drop from Low to Ultra is substantial. At 1080p, it is 220 to 105 FPS, a 52% reduction. At 1440p, it is 139 to 66 FPS, a 53% reduction. At 4K, it is 72 to 35 FPS, a 51% reduction. This consistent percentage drop indicates that the GPU's shading and memory throughput scale linearly with settings, and there is no sudden cliff or bottleneck switch.

GPU Role

The AMD Radeon RX 5700 XT is based on the Navi 10 chip with RDNA 1.0 architecture, fabricated on a 7 nm process by TSMC. It has 2,560 shading units, 160 texture mapping units, and 64 ROPs. The base clock is 1605 MHz, boost clock is 1905 MHz, and game clock is 1755 MHz. Memory is 8 GB of GDDR6 on a 256-bit bus, providing 448.0 GB/s of bandwidth. The GPU's pixel rate is 121.9 GPixel/s, texture rate is 304.8 GTexel/s, and FP32 performance is 9.754 TFLOPS. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, with a TDP of 225 W and a suggested PSU of 550 W.

In synthetic benchmarks, the RX 5700 XT scores 16,277 in PassMark G3D and 7,650 in PassMark GPU compute. 3DMark Steel Nomad DX12 yields 2,134. Geekbench OpenCL scores 9,524, Vulkan scores 68,310, and Metal scores 74,647. The average benchmark score is 16,361, placing it in the 59th percentile of all GPUs. The nearest rivals show it is tightly clustered: the AMD Radeon Pro 5600M scores 16,351 (0.1% behind), the NVIDIA RTX PRO 6000 Blackwell scores 16,408 (0.3% ahead), the AMD Radeon PRO W7500 scores 16,415 (0.3% ahead), and the NVIDIA GeForce RTX 5090 D V2 scores 16,504 (0.9% ahead).

For Pc Building Simulator, the GPU's 8 GB VRAM and 448.0 GB/s bandwidth are the key specifications. The game's measured FPS at 4K Ultra (35 FPS) and 4K High (36 FPS) suggests the GPU is running out of memory bandwidth or fill rate at that resolution. The fact that High and Ultra are nearly identical at 4K (36 vs 35 FPS) while Low at 4K reaches 72 FPS indicates that the GPU's shading units are the constraint, not VRAM capacity, as Low settings reduce shading load significantly. The 59th percentile ranking aligns with the combo's overall rank of 2,769 out of 3,723, reinforcing that the GPU is the performance limiter.

The GPU's boost clock of 1905 MHz and FP32 of 9.754 TFLOPS are modest by today's standards, which explains why the card cannot maintain high frame rates at 4K. The data shows the GPU's performance degrades predictably with resolution and settings, with no anomalies that would suggest driver issues or thermal throttling. The RX 5700 XT is an end-of-life product, and its measured performance in this game reflects its age relative to the CPU.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target resolution and desired frame rate. At 1080p, the Medium preset provides 156 FPS with a min of 132 FPS, which is smooth and well above the 60 FPS threshold. High at 1080p offers 110 FPS, still comfortable, but Ultra at 105 FPS adds only 5 FPS over High while increasing graphical load. The data suggests 1080p High is the best balance, as it delivers 110 FPS with no min FPS data reported, implying consistent frame times.

At 1440p, Medium at 98 FPS (min 84) is the recommended preset for smooth gameplay. High at 69 FPS is playable but closer to the 60 FPS threshold, and Ultra at 66 FPS offers no meaningful improvement. The 84 FPS minimum for Medium indicates the worst-case frame rate stays above 60 FPS, making it the safest choice for a consistent experience. Low at 139 FPS is excessive for most displays and sacrifices visual quality unnecessarily.

At 4K, the choices are more constrained. Low at 72 FPS is the only preset that maintains a comfortable frame rate above 60 FPS. Medium at 51 FPS (min 44) is borderline, with drops below 60 FPS. High at 36 FPS and Ultra at 35 FPS are not recommended for smooth gameplay, as they fall well below the 60 FPS standard. For 4K users, Low settings provide the best experience, while Medium is acceptable if the user can tolerate occasional drops to 44 FPS.

Across all resolutions, the Medium preset offers the most consistent frame pacing, as it is the only preset with min FPS data. The min-to-average ratio is 0.85 at 1080p (132/156), 0.86 at 1440p (84/98), and 0.86 at 4K (44/51), showing stable performance. High and Ultra presets lack min FPS data, which could indicate either consistent performance or unrecorded variance. Given the data, Medium is the recommended preset for users prioritizing stability, while Low is the fallback for 4K or high-refresh-rate 1080p displays.
