Pc Building Simulator

The AMD Ryzen 9 9900X and NVIDIA GeForce RTX 4080 form a strong high‑end desktop pairing. In Pc Building Simulator, measured data shows this combination delivers consistently high frame rates across all tested resolutions and quality settings. The 12‑core, 24‑thread CPU with a 4.4 GHz base and 5.6 GHz boost, together with a 16 GB GDDR6X GPU and its 2505 MHz boost clock, keep the game well above playable thresholds even at 4K. The following sections break down how the system scales, which component dominates in different scenarios, and how it ranks against other tested configurations.

Resolution Scaling

The measured FPS list shows the expected trend: as resolution increases from 1080p to 4K, average frame rates drop at every quality level. Looking at the High setting, the 1080p average of 235 FPS falls to 148 FPS at 1440p and then to 78 FPS at 4K. This demonstrates a distinct pattern where the transition from 1080p to 1440p removes more frames than the transition from 1440p to 4K. At Low settings, the same pattern appears: 470 FPS at 1080p, 297 FPS at 1440p, and 155 FPS at 4K. The scaling difference shows that 1080p low is likely CPU‑bound, since the GPU can render frames at an extremely high rate, while 4K Low is still fast but increasingly reliant on the GPU.

The Medium setting provides min and max figures as well. At 1080p Medium, the average is 333 FPS with a minimum of 283 FPS and a maximum of 383 FPS. At 1440p Medium, the average drops to 210 FPS with a min/max of 179/242 FPS. At 4K Medium, the min/max is 93/126 FPS, yielding an average of 110 FPS. The min values suggest that the combo is never close to confounding the CPU at those resolutions – even the 4K Medium minimum of 93 FPS is well above the native refresh rate of the most standard monitors. The Ultra setting mirrors High with a negligible difference: 1080p Ultra averages 224 FPS, 1440p Ultra 141 FPS, and 4K Ultra 74 FPS. The gap between High and Ultra is so small that the difference is almost imperceptible, indicating that Ultra adds only marginal overhead on top of High – the bottleneck shifts progressively to the GPU as resolution rises.

What does this tell us about the limiting component? At 1080p Low, the 470 FPS figure is far beyond any display refresh, meaning the CPU is feeding the GPU a nearly unlimited workload. At 4K Ultra, the 74 FPS result is a clear sign that the GPU is the constraining element. The curve shows a steady shift from CPU‑limited at 1080p Low to GPU‑limited at 4K Ultra, with the combination being balanced enough that neither component falls far behind at any tested setting.

CPU Role

The Ryzen 9 9900X belongs to AMD’s 9000 series, built on TSMC’s 4 nm process with the Zen 5 architecture (Granite Ridge). It has 12 cores and 24 threads, a base clock of 4.40 GHz and a boost of 5.60 GHz. The CPU’s cache layout is 80 KB L1 per core, 1 MB L2 per core, and 64 MB of shared L3. This Zen 5 design also includes Radeon Graphics, though the game runs on the dedicated RTX 4080. For the benchmark database, the 9900X has a 92nd percentile rating among all tested CPUs and an average benchmark score of 57498. Its closest rivals in overall scores are the AMD EPYC 9015 (57555, 0.1% weaker) and the AMD EPYC 7313 (57399, 0.2% stronger). The Intel Core i9-14900 scores 58115, putting it 1.1% ahead of the 9900X, and the Xeon Platinum 8260M is 1.4% ahead as well.

In Pc Building Simulator, the data shows the CPU is not the bottleneck at low resolution or low settings. The 470 FPS achieved at 1080p Low is a strong signal that the 12 cores and 24 threads have substantial headroom. The game’s simulation workloads likely exploit multiple threads, but the CPU’s single‑core performance is equally strong: the Cinebench R23 single‑core score is 2252, and Geekbench single‑core is 3010. The measured minimum FPS in medium settings – 283 FPS at 1080p, 242 FPS at 1440p, and 126 FPS at 4K – confirms that frame‑time spikes are rare and the CPU rarely bottlenecks the pipeline.

The launch MSRP of the CPU is $499. Given the level of performance shown here, the CPU offers high raw compute, but the actual game frame rates are dictated by the GPU at all traditional gaming resolutions. The biggest takeaway: this CPU will not hold back the RTX 4080 in HEAD‑UP situations, and its long‑term headroom means future games that use more cores, will benefit from the 12‑core design.

GPU Role

The NVIDIA GeForce RTX 4080 is built on the Ada Lovelace architecture (AD103 chip, 5 nm TSMC process). It packs 9728 shading units, 304 TMUs, and 112 ROPs, with 76 RT cores equipped for ray tracing. The GPU runs at a base 2205 MHz and boosts to 2505 MHz, with 16 GB of sample memory across a 256‑bit bus running effective memory at 22.4 Gbps, giving a bandwidth of 716.8 GB/s to the card. The GPU occupies three slots and uses a single 16‑pin power connector; the PSU recommended for it is 700 W.

For compute performance, the PassMark G3D score reaches 34457, and the 3DMark Steel Nomad DX12 test gives 6567. Its overall average benchmark score is 54247. Among its closest rivals, the RTX 4080 SUPER, with a score 54209, is 0.1% behind the 4080; the AMD Radeon Pro W5700X is 1.1% higher, the Radeon RX 6750 GRE 12 GB is 2.6% higher, and the Radeon 8060S is 2.7% higher. These numbers indicate that the 4080 still holds its own among the mid‑range of high‑performance graphics cards, especially in the ray‑tracking tests.

In Pc Building Simulator, the gameplay shows the GPU scaling clearly. The transition from 1080p Medium (average 333 FPS) to 4K Medium (110 FPS) is almost a three‑fold loss, and the Ultra pair goes from 224 FPS to 74 FPS. The only setting where the GPU stands out as the absolute limit is at the highest resolution and maximum quality: Ultra at 4K gets just 74 FPS average. At 4K High the average is exactly 78 FPS, which is still playable but not the high‑refresh experience seen at lower resolutions. The 16 GB of VRAM is ample for the game, and the G‑class rendering pipeline of the engine is well fed.

The launch MSRP for the GPU is 1,199 USD. The card’s strong showing in this title is largely due to its massive compute power (48.74 TFLOPS FP32 and a pixel rate of 280.6 GPixel/s). The results show that the RTX 4080 delivers over 250 FPS in 1080p Ultra and never drops below 74 FPS at 4K Ultra, confirming its position as a top‑tier GPU for high‑refresh 1440p and 4K gaming.

Measured FPS Breakdown

1920×1080:

• Low: 470 FPS average.
• Medium: 333 FPS (min 283, max 383).
• High: 235 FPS.
• Ultra: 224 FPS.

At 1080p, the game aims for massive FPS, and the CPU/GPU combination produces triple‑digit FPS even under the highest settings. The tiny 11‑frame difference between High (235) and Ultra (224) suggests that the Ultra preset adds little additional GPU load, so the CPU headroom is still large.

2560×1440:

• Low: 297 FPS.
• Medium: 210 FPS (min 179, max 242).
• High: 148 FPS.
• Ultra: 141 FPS.

Moving to 1440p, the drop is noticeable, but all the averages stay above 140 FPS. The Medium min of 179 FPS is excellent, ensuring a smooth experience even for those with high‑refresh 1440p monitors. The High to Ultra gap is 7 FPS, reinforcing that Ultra is essentially a visual tweak rather than a heavy burden.

3840×2160:

• Low: 155 FPS.
• Medium: 110 FPS (min 93, max 126).
• High: 78 FPS.
• Ultra: 74 FPS.

4K is where the GPU starts to “feel” the load. The Medium value of 110 FPS is still very playable, but the High and Ultra settings are within 4 FPS of each other (the same pattern as lower resolutions), showing that the graphics settings scaling is modest. The fact that the system can maintain an average above 70 FPS at 4K Ultra from a dataset that only uses a 74 FPS Ultra, means that the combo is suitable for both 4K60 and mid‑refresh 4K monitors, depending on the chosen preset.

How This Combo Ranks

The combined rank of this CPU/GPU pair in Pc Building Simulator is 171 out of 3723 tested configurations. This puts it comfortably in the top brackets of the database, indicating that it provides a strong experience for the entire game. The data set flags it as measured, meaning it is the real observed performance rather than a projection.

Placing it in perspective: 171st of 3723 means it fills a spot within the top 200 of almost 4,000 configs, that translates to the frame rates you see in the measured breakdown. The CPU sits in the 92nd percentile among all CPUs, while the GPU is in the 86th percentile. That the combination performs slightly better than the raw CPU percentile suggests that the CPU and GPU work together without either becoming a severe bottleneck until pushed to 4K Ultra.
