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

Moving from 1920x1080 to 3840x2160 reveals how this pairing of AMD Ryzen 7 7700 and Radeon RX 9070 responds to pixel-count pressure. At High settings, the average framerate falls from 173 FPS at 1080p to 109 FPS at 1440p, then to 57 FPS at 4K. That is a drop of 64 FPS between 1080p and 1440p, and another 52 FPS between 1440p and 4K. The scaling is steep but not linear, suggesting the GPU begins to dominate as resolution climbs.

The Low preset tells a very different story. At 1080p Low, the combo produces 346 FPS, which is an enormous headroom figure. At 1440p Low, it still manages 219 FPS, and at 4K Low, it holds onto 114 FPS. The relative drop from 1080p to 4K at Low settings is about 67% (346 down to 114), whereas at High settings the drop is about 67% as well (173 down to 57). This consistency across presets points to a GPU-bound scenario at 4K, even when the workload is lightened.

Looking at Medium settings, the measured rows include min and max FPS, which gives more texture. At 4K Medium, the average is 81 FPS with a min of 69 and max of 93. At 1440p Medium, the average jumps to 155 FPS with min 132 and max 178. At 1080p Medium, the average is 245 FPS with min 209 and max 282. The spread between min and max FPS narrows as resolution drops—at 1080p the gap is 73 FPS, while at 4K it is only 24 FPS. This suggests that at lower resolutions, the CPU or memory subsystem introduces more variance, while at 4K the GPU's consistent frame pacing dominates.

Ultra settings show the largest absolute penalty from resolution scaling. The average FPS at 1080p Ultra is 165, at 1440p Ultra it is 104, and at 4K Ultra it drops to 54. That final figure sits below the 60 FPS threshold, which is notable for a game like Pc Building Simulator that is not typically considered a demanding AAA title. The data indicates that at 4K Ultra, the RX 9070 is the primary limiter, as the CPU's 8 cores and 16 threads are unlikely to be saturated in a simulation title.

The interesting anomaly is that High and Ultra settings produce nearly identical results at 1080p—173 vs 165 FPS—which implies that the extra visual features in Ultra are almost free at this resolution. However, at 4K, the gap widens to 3 FPS (57 vs 54), still small but measurable. This suggests that the GPU has enough headroom at 1080p to absorb the Ultra overhead, but at 4K it starts to feel the strain.

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

For 4K displays, the Medium preset stands out as the sweet spot. The average of 81 FPS is comfortably above the 60 FPS target, and the min of 69 FPS ensures no noticeable stutter. High settings at 4K produce 57 FPS, which is playable but close to the edge, and Ultra at 54 FPS dips below that threshold. Low at 4K delivers 114 FPS but sacrifices visual fidelity in a game that is about seeing details in your virtual PC builds.

At 1440p, the decision becomes easier. High settings yield 109 FPS, which is smooth and visually rich. Ultra at 104 FPS is only 5 FPS behind, so the cost of maxing out is minimal. Medium at 155 FPS is overkill unless you have a high-refresh display, but the extra headroom could help with frame time consistency. Low at 219 FPS is for competitive play or extreme refresh rates, which is not the typical use case for this simulation genre.

At 1080p, every preset except Ultra exceeds 165 FPS. High at 173 FPS and Ultra at 165 FPS are nearly indistinguishable in practice, so the recommendation is to use Ultra for maximum visual quality. Medium at 245 FPS and Low at 346 FPS are only relevant for esports-style monitors, but this game does not benefit from that level of responsiveness. The min FPS data at Medium (209 FPS at 1080p) shows there is no danger of drops even in complex scenes.

The measured data suggests that the optimal experience per preset is: for 4K, use Medium (81 FPS avg, 69 min); for 1440p, use Ultra (104 FPS avg) or High (109 FPS) depending on preference; for 1080p, use Ultra without hesitation (165 FPS avg). The difference between High and Ultra at 1440p is negligible, but at 4K, Medium is the only preset that guarantees a 60+ FPS floor.

How This Combo Ranks — use comboRankInGame vs other tested combos

The rank of 1082 out of 3723 tested combos places this system in the 71st percentile of all configurations tested in Pc Building Simulator. That means roughly 29% of tested combos perform better. For a game released in 2019, this is a strong showing, but it raises questions about what those higher-ranked combos are doing differently—likely more powerful GPUs at 4K or higher-core-count CPUs for simulation logic.

The rank is particularly interesting because the individual components have different percentile standings. The Ryzen 7 7700 sits at the 87th percentile among all CPUs, while the RX 9070 is at the 69th percentile among all GPUs. The combined result of 71st percentile (based on the rank) is closer to the GPU's percentile than the CPU's, which suggests that the GPU is the more limiting factor in this pairing for this specific game.

Comparing to the nearest rival combos is not possible directly, but the CPU's nearest rivals show how close the 7700 is to other processors. The AMD Ryzen AI 9 365 has an average score 0.1% higher, the Intel Core 5 221E is 0.2% lower, the AMD Ryzen 9 270 is 0.4% lower, and the Intel Core i9-13905H is 0.6% lower. This clustering means the CPU is in a very tight performance band, so the rank difference in-game is likely driven by the GPU.

The GPU's nearest rivals are more spread out. The NVIDIA GeForce GTX TITAN Z has an average score 0.6% higher, the AMD Radeon RX 6800S is 0.8% lower, the NVIDIA GeForce RTX 3080 Mobile is 1.1% higher, and the NVIDIA GeForce RTX 2080 SUPER is 1.2% lower. These deltas are small, indicating that the RX 9070 is positioned in a highly competitive segment where performance differences are minor.

For Pc Building Simulator specifically, the rank of 1082 suggests that this combo is more than capable for the game's typical demands—building and testing virtual PCs. The game's simulation nature may not stress the GPU as much as other titles, which could explain why the rank is not higher despite the strong CPU.

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

The AMD Ryzen 7 7700 brings 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.30 GHz. This is a Zen 4 architecture part built on a 5 nm process, with 32 MB of shared L3 cache. For a simulation game like Pc Building Simulator, the core count is more than sufficient, as the game's logic likely does not scale beyond a handful of threads. The high boost clock of 5.30 GHz helps with single-threaded performance, which is often more important in simulation titles.

The benchmark scores for the CPU show strong multi-threaded capability: Cinebench R23 multicore scores 18,760, while single-core scores 1,930. Geekbench multicore is 15,371 and single-core is 2,525. The 3DMark 16-thread score of 8,484 is nearly identical to the max-thread score of 8,479, which indicates that the CPU reaches its performance ceiling with 16 threads and does not benefit from additional threads beyond that. This is relevant for Pc Building Simulator, where the game's simulation loop may use fewer threads.

The CPU's 87th percentile ranking among all CPUs means it outperforms the majority of processors. Its nearest rivals are all within 0.6% of its average score, which shows that the 7700 is not a performance outlier but rather a solid mid-to-high range option. In the context of this game, the CPU's role is to feed the GPU with enough data to avoid bottlenecks, and the measured FPS at 1080p (346 FPS on Low) confirms that the CPU is not limiting even at high frame rates.

The TDP of 65 W is modest for an 8-core part, which means thermal headroom is not a concern. The memory bandwidth of 83.2 GB/s over dual-channel DDR5 is adequate for the game's data flow. The L3 cache of 32 MB is shared across all cores, which helps with data locality in simulation workloads. The CPU's integrated Radeon Graphics are irrelevant since a discrete GPU is present.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the measured averages are: Low 346 FPS, Medium 245 FPS (min 209, max 282), High 173 FPS, Ultra 165 FPS. The progression from Low to Ultra shows a 52% reduction in FPS (346 to 165). The Medium preset's min of 209 FPS is still well above the 165 FPS Ultra average, indicating that the drop from Medium to High is the largest step—72 FPS difference between Medium and High.

At 2560x1440, the averages are: Low 219 FPS, Medium 155 FPS (min 132, max 178), High 109 FPS, Ultra 104 FPS. The gap between High and Ultra narrows to just 5 FPS, while the gap between Medium and High is 46 FPS. This suggests that the visual fidelity gains from Medium to High are more expensive than those from High to Ultra at this resolution.

At 3840x2160, the averages are: Low 114 FPS, Medium 81 FPS (min 69, max 93), High 57 FPS, Ultra 54 FPS. The drop from Low to Medium is 33 FPS, from Medium to High is 24 FPS, and from High to Ultra is only 3 FPS. The Ultra preset at 4K produces the lowest average of any configuration tested, at 54 FPS. The Medium preset's min of 69 FPS is higher than the High and Ultra averages, making it the only 4K preset that maintains a consistent 60+ FPS experience.

The full matrix shows that 1080p Ultra (165 FPS) outperforms 1440p High (109 FPS) and 4K Medium (81 FPS), which is expected given the pixel count differences. However, the relative scaling from 1080p to 4K at each preset is roughly similar, indicating that the GPU scales predictably with resolution. The only anomaly is the 4K Ultra result, which falls below 60 FPS and represents the least playable configuration.

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

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture with a Navi 48 chip, featuring 16 GB of GDDR6 memory on a 256-bit bus. The memory bandwidth is 644.6 GB/s, which is substantial for a simulation game that may load many textures and models. The base clock is 1330 MHz, the game clock is 2070 MHz, and the boost clock is 2520 MHz. The 3584 shading units and 128 ROPs provide the raw compute power needed for rendering.

The GPU's 69th percentile ranking among all GPUs places it in the lower half of the top third. Its nearest rivals include the GTX TITAN Z (0.6% higher), RX 6800S (0.8% lower), RTX 3080 Mobile (1.1% higher), and RTX 2080 SUPER (1.2% lower). These small deltas indicate that the RX 9070 is in a tightly contested performance tier. For Pc Building Simulator, the GPU's primary role is to render the 3D view of PC components, which is not graphically intensive compared to modern AAA titles.

The 16 GB VRAM is more than enough for this game, as even at 4K Ultra the measured FPS does not show evidence of VRAM-related drops. The memory bandwidth of 644.6 GB/s ensures that texture streaming is never a bottleneck. The boost clock of 2520 MHz is high, and the measured FPS suggests that the GPU is able to maintain this clock under load, given the consistent scaling from 1080p to 4K.

The GPU's TDP of 220 W and suggested PSU of 550 W are modest for its performance class. The PCIe 5.0 x16 interface provides ample bandwidth for data transfer from the CPU. The 4 nm process node from TSMC keeps power efficiency reasonable, which aligns with the game's non-demanding nature. The RX 9070's performance in this game is more than adequate, with the only weak point being 4K Ultra at 54 FPS, which is a realistic limitation for any GPU in this class.
