Pc Building Simulator

# Pc Building Simulator — AMD Ryzen 9 7900X + AMD Radeon RX 6600

This combination pairs a 12-core Zen 4 flagship-class processor with a mainstream RDNA 2 graphics card, and the measured frame rates in Pc Building Simulator reveal a system whose performance ceiling is almost entirely defined by the GPU rather than the CPU. Across all tested resolutions and settings, the Ryzen 9 7900X provides ample headroom, while the RX 6600's 8 GB frame buffer and 128-bit memory interface become the decisive factors as resolution and quality settings increase. The data shows a predictable scaling pattern that is typical of a simulation title with modest CPU demands, but the absolute FPS numbers indicate that this is a 1080p-oriented configuration that can handle 1440p with settings compromises, while 4K remains largely out of reach for smooth gameplay.

Resolution Scaling

The measured FPS data shows a clear and consistent decline as resolution increases from 1920x1080 to 3840x2160, which strongly indicates that the GPU is the limiting component in this system. At Low settings, the average frame rate drops from 206 FPS at 1080p to 130 FPS at 1440p, a reduction of 76 FPS or roughly 37%. Moving from 1440p to 4K Low, the average falls further from 130 FPS to 68 FPS, another 48% decrease. This halving pattern at each resolution step is classic evidence of a pixel-bound workload where the RX 6600's shading throughput and memory bandwidth are the bottlenecks.

At Medium settings, the scaling is slightly less steep but still pronounced. The average FPS goes from 146 at 1080p, to 92 at 1440p, and finally to 48 at 4K. The drop from 1080p to 1440p is 54 FPS (37%), while the drop from 1440p to 4K is 44 FPS (48%). This consistency across settings levels suggests that the resolution scaling behavior is independent of the quality preset, which is expected when the GPU is fully saturated. The High settings row shows a similar trend: 103 FPS at 1080p, 65 FPS at 1440p, and 34 FPS at 4K. The percentage drops are 37% and 48% respectively, matching the Low settings pattern almost exactly.

The Ultra settings row exhibits the same relative scaling, with averages of 98 FPS at 1080p, 62 FPS at 1440p, and 32 FPS at 4K. The 4K Ultra result of 32 FPS is barely above the threshold commonly considered playable, and the data suggests that this resolution is not viable for this combo in this game. The fact that 4K Ultra (32 FPS) is only slightly lower than 4K High (34 FPS) indicates that the GPU is so heavily constrained at 4K that the additional settings overhead has minimal impact — the renderer is already waiting on the GPU at every frame. This resolution scaling analysis points to a system where the Ryzen 9 7900X is never the bottleneck; the RX 6600's pixel throughput dictates performance at every step.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a Navi 23 chip manufactured on a 7 nm process at TSMC. The GPU operates with a base clock of 1626 MHz, a game clock of 2044 MHz, and a boost clock of 2491 MHz. These clock speeds are relatively high for a mainstream card, but the 8 GB of GDDR6 memory on a 128-bit bus with 224.0 GB/s of bandwidth is the key limitation in Pc Building Simulator. The game's simulation nature means that memory capacity and bandwidth become critical when rendering detailed scenes with many objects, and the data reflects this.

The measured FPS differences between Low and Ultra settings at the same resolution show the GPU's resource constraints. At 1080p, the gap between Low (206 FPS) and Ultra (98 FPS) is 108 FPS, meaning Ultra delivers only 48% of the Low settings frame rate. At 1440p, the gap narrows to 68 FPS (130 vs. 62), and at 4K it is 36 FPS (68 vs. 32). This narrowing gap at higher resolutions is counterintuitive at first glance, but it makes sense when considering that the GPU is already saturated at lower settings at 4K, so the incremental cost of higher quality settings is relatively smaller in absolute FPS terms.

The RX 6600's 1792 shading units, 112 texture units, and 64 ROPs provide the raw compute for this game, and the FP32 throughput of 8.928 TFLOPS is sufficient for 1080p gameplay at high frame rates. The pixel rate of 159.4 GPixel/s and texture rate of 279.0 GTexel/s help explain why the card can achieve 146 FPS at 1080p Medium, but the same metrics are inadequate for 4K. The 8 GB memory capacity is also a factor — while the game does not appear to exceed this at the tested settings based on the FPS data, the steep drop from 1440p to 4K suggests that memory pressure increases significantly at higher resolutions. The GPU's position in the 63rd percentile of all GPUs, with an average benchmark score of 19036, confirms that this is a mid-range part. Its nearest rival, the NVIDIA Quadro K6000, scores 19030 (0% delta), indicating that the RX 6600 sits at the boundary between generations and market segments.

FAQ

Q: Can this system run Pc Building Simulator at 4K with playable frame rates?

A: The data shows that 4K performance is marginal. The best 4K result is 68 FPS at Low settings, but Medium drops to 48 FPS, High to 34 FPS, and Ultra to 32 FPS. Only the Low preset at 4K exceeds 60 FPS, and even that is far below the 1080p results.

Q: What is the best resolution for this combination?

A: Based on the measured FPS, 1920x1080 is the sweet spot. All four settings presets at 1080p exceed 98 FPS, with Low reaching 206 FPS and Medium hitting 146 FPS. The 1440p results are playable but require dropping to Low (130 FPS) or Medium (92 FPS) for smooth performance.

Q: How does the RX 6600 compare to its closest GPU rivals?

A: The RX 6600 has an average benchmark score of 19036, placing it in the 63rd percentile. Its nearest rival is the NVIDIA Quadro K6000 with a score of 19030 (0% delta), followed by the NVIDIA GeForce RTX 4050 Mobile at 19049 (-0.1% delta) and the NVIDIA Tesla K20m at 19089 (-0.3% delta). The RTX 2000 Ada Generation trails at 18954 (0.4% delta).

Q: Is the Ryzen 9 7900X holding back the RX 6600 in this game?

A: The resolution scaling data strongly suggests no. The consistent FPS drops as resolution increases indicate a GPU-bound scenario. The CPU's benchmark scores, including a 29300 Cinebench R23 multicore result and a 91st percentile ranking, far exceed what this simulation title requires.

Q: What is the FPS difference between Medium and Ultra settings at 1080p?

A: At 1080p, Medium averages 146 FPS with a minimum of 124 FPS and maximum of 168 FPS. Ultra drops to 98 FPS average, a reduction of 48 FPS or 33%. The gap is significant but both are playable.

Q: Does the 8 GB VRAM cause issues at higher resolutions?

A: The data indicates that performance degrades sharply at 4K, with the best average being 68 FPS at Low. The drop from 1440p Medium (92 FPS) to 4K Medium (48 FPS) is 44 FPS, suggesting that memory bandwidth and capacity become constraints at 4K, though the game does not exhibit a hard crash or stutter in the measured data.

Settings Recommendations

The measured FPS data provides clear guidance on which settings preset offers the best experience for this hardware combination. At 1920x1080, the Medium preset delivers an average of 146 FPS with a minimum of 124 FPS and a maximum of 168 FPS, which is the balanced choice for most users. The High preset at 103 FPS is also smooth, but the 43 FPS gap between Medium and High suggests that the visual quality difference may not justify the performance cost for a simulation game where UI elements and menus are prominent.

For 2560x1440, the Medium preset at 92 FPS (78 min, 106 max) is the recommended starting point. The High preset at 65 FPS is borderline for fast-paced interactions, while Low at 130 FPS sacrifices too much visual fidelity for the extra headroom. The 1440p Medium result of 92 FPS is only 6 FPS below the 1080p High result of 103 FPS, making it a viable alternative for users with 1440p monitors who want a balance of quality and speed.

At 3840x2160, the data shows that only the Low preset (68 FPS) provides a consistently playable experience. Medium at 48 FPS, High at 34 FPS, and Ultra at 32 FPS all fall below the 60 FPS threshold that most users consider ideal, and the minimum FPS data for Medium (41 FPS) indicates potential stutter during complex scenes. The recommendation is to avoid 4K with this combo unless the user is willing to accept Low settings; otherwise, a resolution drop to 1440p with Medium settings provides a far superior experience.

The Ultra preset offers diminishing returns across all resolutions. At 1080p, Ultra (98 FPS) is only 5 FPS lower than High (103 FPS), but at 1440p the drop from High (65 FPS) to Ultra (62 FPS) is just 3 FPS. The data suggests that Ultra is not a meaningful upgrade over High in this game, while Medium provides the best FPS-per-quality trade-off at every resolution except 4K Low.

How This Combo Ranks

This specific combination of the AMD Ryzen 9 7900X and the AMD Radeon RX 6600 ranks 2894 out of 3723 tested combos in Pc Building Simulator, placing it in the 22nd percentile of all tested configurations. This relatively low ranking is directly attributable to the GPU, as the CPU is among the top-tier options available. The Ryzen 9 7900X's percentile ranking of 91 among all CPUs, with an average benchmark score of 53288, puts it in the top 10% of processors, while the RX 6600's 63rd percentile and 19036 average score are decidedly mid-range.

The rank of 2894 means that 829 tested combos perform worse, but 2893 perform better. This places the combo in the lower-middle portion of the database, which aligns with the measured FPS data showing that 4K is not viable and 1440p requires settings compromises. The CPU's nearest rivals in benchmark scores — the AMD EPYC 7313P (53206, 0.2% delta), Intel Xeon Phi 7290 (53469, -0.3% delta), Intel Xeon 634 (52974, 0.6% delta), and Intel Core i7-14700F (53620, -0.6% delta) — are all within 1% of each other, highlighting that the CPU is not a differentiating factor in this game's performance.

The GPU's rivals — Quadro K6000, RTX 4050 Mobile, Tesla K20m, and RTX 2000 Ada Generation — all score within 0.4% of the RX 6600's average, indicating that the GPU is similarly not an outlier in its class. The combination rank of 2894 out of 3723 reflects that while both components are competent individually, the pairing creates a system that is GPU-limited in this simulation title. Users seeking higher rankings would need a more powerful GPU, while those satisfied with 1080p Medium settings (146 FPS) will find this combo adequate.

Measured FPS Breakdown

The complete measured FPS dataset for this combination in Pc Building Simulator is as follows. At 3840x2160, the High settings preset produces an average of 34 FPS, Low produces 68 FPS, Medium produces 48 FPS with a minimum of 41 and maximum of 55, and Ultra produces 32 FPS. The 4K results show that no preset exceeds 68 FPS, and the gap between Low and Ultra is 36 FPS.

At 2560x1440, High averages 65 FPS, Low averages 130 FPS, Medium averages 92 FPS (78 min, 106 max), and Ultra averages 62 FPS. The 1440p results are more spread out, with a 68 FPS difference between Low and Ultra. The Medium preset's minimum of 78 FPS indicates that even during demanding scenes, the frame rate stays above 60 FPS.

At 1920x1080, High averages 103 FPS, Low averages 206 FPS, Medium averages 146 FPS (124 min, 168 max), and Ultra averages 98 FPS. The 1080p results show the widest spread — 108 FPS between Low and Ultra — which is expected given the headroom available at this resolution. The Medium preset's minimum of 124 FPS ensures a smooth experience even in the most demanding scenes.

The data also reveals that the minimum FPS values are only provided for the Medium preset at each resolution: 124 FPS at 1080p, 78 FPS at 1440p, and 41 FPS at 4K. These minimums represent 85%, 85%, and 85% of their respective averages (146, 92, and 48), suggesting consistent frame pacing at Medium settings. The maximum FPS values for Medium are 168 at 1080p, 106 at 1440p, and 55 at 4K, showing that the GPU can occasionally burst above its average but remains constrained at higher resolutions.

CPU Role

The AMD Ryzen 9 7900X is a 12-core, 24-thread processor from the 7000 series, built on Zen 4 architecture with a 5 nm process at TSMC. Its base clock is 4.70 GHz with a boost clock of 5.60 GHz, and it carries a TDP of 170 W. The CPU supports DDR5 memory with a dual-channel bus and 83.2 GB/s of bandwidth, along with PCIe Gen 5 (24 lanes). Its cache hierarchy includes 64 KB L1 per core, 1 MB L2 per core, and 64 MB shared L3, which provides ample capacity for simulation workloads.

In Pc Building Simulator, the CPU's role is primarily to manage the game's logic, AI, and physics, but the measured FPS data shows that the GPU is the bottleneck at all resolutions. The CPU's benchmark scores are exceptionally high: Cinebench R23 multicore reaches 29300, Geekbench multicore scores 19267, and Passmark multithread scores 51406. The single-thread performance is also strong, with Cinebench R23 singlecore at 2016.5 and Passmark singlethread at 4238. These scores place the 7900X in the 91st percentile of all CPUs, with an average benchmark score of 53288.

The nearest CPU rivals in the benchmark database — the AMD EPYC 7313P, Intel Xeon Phi 7290, Intel Xeon 634, and Intel Core i7-14700F — all score within 0.6% of the 7900X, confirming that this processor is at the top of its class. In the context of this game, the CPU's 12 cores and 24 threads are far more than required; the FPS scaling from 1080p to 4K shows no sign of CPU limitations, such as the frame rate plateauing or failing to increase with lower resolutions. The fact that 1080p Low achieves 206 FPS indicates that the CPU can feed the GPU at high frame rates, but the RX 6600's 8 GB memory and 128-bit bus ultimately cap the system's performance. The 7900X is an overqualified partner for the RX 6600 in this title, and the combination rank of 2894 out of 3723 reflects the GPU's limiting role rather than any CPU deficiency.
