Pc Building Simulator

Pc Building Simulator is a simulation title that scales unusually well across hardware, and the measured results for the Intel Core i7-14700KF paired with the AMD Radeon RX 7900 XTX show a system that remains fluid from 1080p through 4K, though the performance curve reveals where each component's workload begins and ends.

Resolution Scaling

The measured FPS data shows a dramatic drop as resolution increases, but the pattern is not linear. At 1080p with Low settings, the combo produces 426.4 FPS. Moving to 1440p Low drops that to 267.9 FPS, a 37% reduction. At 4K Low, the average falls to 138.4 FPS, which is another 48% cut from 1440p. This steep scaling from 1080p to 4K indicates that the system is heavily CPU-limited at lower resolutions; the GPU has ample headroom, and the frame rate is being capped by the processor's ability to feed the renderer.

Looking at the Ultra preset, the scaling is less severe but still pronounced. At 1080p Ultra the combo hits 205.1 FPS, at 1440p Ultra it drops to 126.4 FPS, and at 4K Ultra it settles at 67.6 FPS. The 1080p-to-1440p drop is 38%, while the 1440p-to-4K drop is 46%. The fact that the percentage losses are similar across both resolution steps suggests that the GPU is becoming the primary limiter as pixel count rises, but the CPU is still contributing enough overhead that the GPU cannot fully stretch its legs even at 4K.

The most telling data point is the difference between Low and Ultra at each resolution. At 1080p, Low produces 426.4 FPS versus 205.1 FPS at Ultra, a 2.08x gap. At 1440p, the gap narrows to 2.12x (267.9 vs 126.4). At 4K, the gap is 2.05x (138.4 vs 67.6). This consistency across resolutions implies that the settings preset affects the GPU workload proportionally, but the absolute FPS ceiling at each resolution is set by a combination of CPU and GPU capabilities. The 4K Ultra result of 67.6 FPS is just above the 60 FPS threshold, while 4K High at 70.9 FPS offers a slight margin.

GPU Role

The AMD Radeon RX 7900 XTX is built on the RDNA 3.0 architecture with a Navi 31 chip, manufactured on a 5 nm process at TSMC. It carries 24 GB of GDDR6 memory on a 384-bit bus, yielding 960.0 GB/s of bandwidth. The base clock is 1929 MHz, with a boost clock of 2498 MHz and a game clock of 2365 MHz. Memory runs at 2500 MHz with 20 Gbps effective speed. The GPU has 6144 shading units, 384 texture mapping units, and 192 raster operations units, along with 96 ray tracing cores.

In Pc Building Simulator, the GPU's role becomes evident when comparing the measured FPS across settings at a fixed resolution. At 4K, raising from Low to Medium increases the average from 138.4 FPS to 98.1 FPS, a 29% reduction. Moving from Medium to High drops to 70.9 FPS, another 28% cut. From High to Ultra, the average falls to 67.6 FPS, a 4.7% reduction. The diminishing penalty from High to Ultra suggests that the Ultra preset adds only marginal GPU load beyond High, or that the game's Ultra settings are not substantially more demanding than High in this scene.

The GPU's benchmark scores place it at the 85th percentile among all GPUs, with an average benchmark score of 44019. Its nearest rivals include the AMD Radeon Pro 580 (avg 44195, delta -0.4%), the NVIDIA GeForce RTX 4090 Mobile (avg 43667, delta 0.8%), and the NVIDIA Quadro M6000 (avg 43313, delta 1.6%). The 7900 XTX trails the Radeon Pro 580 by 0.4% and the RTX 4070 Ti (avg 44900, delta -2%) by 2%. This indicates that while the 7900 XTX is a high-end part, it is not the absolute top performer in the database, and its 4K performance in this game reflects that positioning.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor from the Core 14th Gen series, built on the Raptor Lake architecture with a 10 nm process. Its base clock is 3.40 GHz, and it boosts to 5.60 GHz. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3. It supports DDR4 and DDR5 memory in a dual-channel configuration, and it uses PCIe Gen 5 with 16 lanes from the CPU.

In this game, the CPU's influence is most apparent at 1080p, where the frame rates exceed 200 FPS even at Ultra. The measured 426.4 FPS at 1080p Low and 299.7 FPS at 1080p Medium show that the processor can push very high frame rates when the GPU is not the bottleneck. The fact that 1080p High (215.5 FPS) and 1080p Ultra (205.1 FPS) are relatively close to each other, while both are far below the Low preset, indicates that the GPU load from increased settings is becoming significant even at 1080p.

The i7-14700KF's benchmark scores reinforce its strength. It achieves a Cinebench R23 multicore score of 44557 and a single-core score of 6290. In Geekbench, it scores 19287 multicore and 2972 single-core. Its PassMark multithread score is 52425, and its single-thread score is 4480. The CPU sits at the 96th percentile among all CPUs, with an average benchmark score of 70104. Its nearest rivals are the Intel Core i7-14700K (avg 70074, delta 0%), the AMD EPYC 9115 (avg 69887, delta 0.3%), and the AMD Ryzen 9 9950X (avg 70420, delta -0.4%). The i7-14700KF is essentially tied with the i7-14700K, 0.3% ahead of the EPYC, and 0.4% behind the Ryzen 9 9950X.

How This Combo Ranks

The combo of the Intel Core i7-14700KF and AMD Radeon RX 7900 XTX ranks 195th out of 1769 tested combinations in Pc Building Simulator. This places it in the top 11% of all combos in the database for this game. Given that the CPU is at the 96th percentile and the GPU is at the 85th percentile, the combo rank of 195 suggests that the pairing is well balanced for this title, but not optimal.

The rank is likely influenced by the fact that Pc Building Simulator is not a graphically demanding game by modern standards. The 7900 XTX's 85th percentile GPU performance is good, but the game's low graphical requirements mean that a less powerful GPU could achieve similar frame rates at lower resolutions. The CPU's high percentile is more relevant here, as the game's simulation logic can benefit from strong single-thread and multi-thread performance. The fact that the combo still lands at 195 out of 1769 suggests that there are 194 other combinations that deliver better FPS in this specific title, likely with even stronger CPUs or GPUs that excel in the game's particular workload.

Settings Recommendations

Based on the measured FPS data, the Ultra preset at 1440p delivers 126.4 FPS, which is well above the 60 FPS threshold and provides a smooth experience. At 4K, the Ultra preset drops to 67.6 FPS, which is still playable but leaves little headroom for demanding scenes. The High preset at 4K produces 70.9 FPS, which is actually 4.9% higher than Ultra at the same resolution, suggesting that High is the better choice for 4K if you want to prioritize frame rate stability over the marginal visual gains from Ultra.

For 1080p, the Ultra preset at 205.1 FPS is more than sufficient for any display, and the Medium preset at 299.7 FPS offers a significant boost for high-refresh-rate monitors. The Low preset at 426.4 FPS is likely overkill for most users, unless the goal is to maximize FPS for competitive play or benchmarking. The data indicates that the Medium preset at 1440p (189.1 FPS) is the sweet spot for balancing visual quality and performance, as it is 50% faster than High at the same resolution while only stepping down one quality tier. At 4K, the Medium preset (98.1 FPS) is the recommended choice, as it stays comfortably above 60 FPS while offering better visuals than Low.

Measured FPS Breakdown

At 3840x2160, the measured averages are as follows: Low settings produce 138.4 FPS, Medium produces 98.1 FPS, High produces 70.9 FPS, and Ultra produces 67.6 FPS. The spread from Low to Ultra is 70.8 FPS, with the largest single-step drop occurring between Medium and High (27.2 FPS).

At 2560x1440, the averages are: Low at 267.9 FPS, Medium at 189.1 FPS, High at 133.6 FPS, and Ultra at 126.4 FPS. The Medium-to-High drop is 55.5 FPS, which is the largest step here, while the High-to-Ultra drop is only 7.2 FPS, indicating diminishing returns from the highest preset.

At 1920x1080, the averages are: Low at 426.4 FPS, Medium at 299.7 FPS, High at 215.5 FPS, and Ultra at 205.1 FPS. The Low-to-Medium drop is 126.7 FPS, the Medium-to-High drop is 84.2 FPS, and the High-to-Ultra drop is 10.4 FPS. This pattern shows that the game's settings have the most impact at lower resolutions, where the CPU is less of a limiting factor and the GPU's workload increases more noticeably with each preset step.
