Pc Building Simulator

The Intel Core Ultra 7 265K and NVIDIA GeForce RTX 4090 combination delivers extreme performance in Pc Building Simulator, placing in the top percentile of all tested configurations. The data shows a system that is heavily GPU-limited at higher resolutions but possesses enough CPU headroom to push frame rates past 400 FPS at 1080p on low settings. This analysis breaks down the measured results, component roles, and scaling characteristics.

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

The Intel Core Ultra 7 265K is a 20-core, 20-thread processor based on the Arrow Lake architecture, built on a 3 nm process by TSMC. It operates with a base clock of 3.90 GHz and a boost clock of 5.50 GHz, with a 125 W TDP. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and a shared 30 MB L3 pool. Memory support is dual-channel DDR5 with a bandwidth of 102.4 GB/s. The processor also carries an integrated Arc Xe-LPG Graphics 64EU unit, though discrete GPU testing bypasses this.

In synthetic benchmarks, the 265K scores 35,850 in Cinebench R23 multi-core and 2,020 in single-core. Its Geekbench scores are 23,085 multi-core and 2,713 single-core. PassMark multi-thread performance is 58,594, with single-thread at 4,928. The processor holds a 94th percentile ranking versus all CPUs, with an average benchmark score of 70,879. Compared to nearest rivals, it trails the Intel Xeon 6511P by 0.2% (score 71,051) and the Intel Xeon Platinum 8270 by 0.7% (score 71,370), but leads the Intel Core i7-14700KF by 1% (score 70,163) and the AMD Ryzen 7 9700F by 1.3% (score 69,996).

For Pc Building Simulator, the CPU role is primarily about maintaining high frame rates at lower resolutions where the GPU is not saturated. The measured data shows that at 1080p Low, the combo achieves 496 FPS average. This is far beyond typical display refresh rates and indicates the 265K’s strong single-thread performance (2,020 Cinebench R23 single-core) is sufficient to feed the RTX 4090 without creating a bottleneck. The 20 physical cores (no hyperthreading, 20 threads) provide ample parallel throughput for the simulation’s background logic, but the game’s rendering demands at high settings shift the burden to the GPU. The data suggests that even at 4K Ultra, where the average FPS drops to 82, the CPU is not the limiting factor; the GPU is. The processor’s 94th percentile ranking confirms it sits among the top tier of desktop CPUs, making it a non-issue for this title.

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

The NVIDIA GeForce RTX 4090 is the flagship of the GeForce 40-series, built on the Ada Lovelace architecture with the AD102 chip on a 5 nm process. It features 16,384 shading units, 512 TMUs, and 176 ROPs, along with 128 RT cores and 512 tensor cores. The GPU operates at a base clock of 2235 MHz and a boost of 2520 MHz, with memory clocked at 1313 MHz (21 Gbps effective). It has 24 GB of GDDR6X memory on a 384-bit bus, delivering 1.01 TB/s of bandwidth. The card is rated for a 450 W TDP and requires a 850 W suggested PSU, with a triple-slot cooler and a single 16-pin power connector.

In synthetic tests, the RTX 4090 scores 38,194 in PassMark G3D and 26,613 in PassMark GPU Compute. Its Geekbench OpenCL score is 255,416 and Vulkan is 271,631. The GPU holds an 88th percentile ranking versus all GPUs, with an average benchmark score of 60,347. Compared to nearest rivals, it is effectively tied with the Intel Arc Pro A60 (delta 0%, score 60,326) and the AMD Radeon Pro Vega 48 (delta 0.3%, score 60,140), while leading the AMD Radeon Pro W6600M by 2.5% (score 61,896) and the AMD Radeon PRO V710 by 2.9% (score 58,657). Note that these rivals are workstation-oriented cards, not gaming equivalents, which skews the comparison.

For Pc Building Simulator, the GPU’s role is dominant at higher resolutions and settings. The measured FPS data shows a clear pattern: at 4K Ultra, the average is 82 FPS; at 1440p Ultra, it rises to 156 FPS; at 1080p Ultra, it reaches 247 FPS. The 24 GB VRAM is far more than this game requires, but the rendering workload scales with resolution. The boost clock of 2520 MHz, combined with 1.01 TB/s memory bandwidth, allows the GPU to handle the game’s visual effects without stutter, as evidenced by the min FPS values at Medium settings (103 FPS at 4K, 197 FPS at 1440p, 313 FPS at 1080p). The 88th percentile GPU ranking indicates it is near the top of the database, and the data confirms that the RTX 4090 is the primary driver of frame rates in this title, especially when settings are raised.

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

The measured FPS data reveals a steep scaling curve from 1080p to 4K, which points to the GPU as the limiting component at higher resolutions. At Low settings, the average FPS drops from 496 at 1080p to 328 at 1440p (a 33.9% reduction) and then to 171 at 4K (a 65.5% reduction from 1080p). At Ultra settings, the averages are 247 FPS at 1080p, 156 FPS at 1440p (a 36.8% drop), and 82 FPS at 4K (a 66.8% drop). This pattern is consistent across all settings: the frame rate roughly halves when moving from 1080p to 4K, which is expected for a GPU-bound workload where pixel count quadruples.

The data also shows that the scaling from 1080p to 1440p is less severe than from 1440p to 4K, suggesting that at 1080p the CPU still has some influence. At 1080p Low, 496 FPS is so high that the CPU’s single-thread performance (2,020 Cinebench R23) may be near its limit, but the GPU is still not fully saturated. At 4K, the GPU is clearly the constraint: the 82 FPS at Ultra is only 33% of the 1080p Low result, indicating the RTX 4090’s rendering throughput is the bottleneck. The min FPS values at Medium settings (103 FPS at 4K, 197 FPS at 1440p, 313 FPS at 1080p) maintain a similar ratio, confirming the GPU’s dominance. In summary, resolution scaling shows a GPU-limited system at 1440p and 4K, with the CPU having negligible impact on frame rates beyond 1080p.

Settings Recommendations

Based on the measured FPS rows, the best experience depends on the target resolution. At 1920x1080, all settings exceed 247 FPS average, with Low hitting 496 FPS. For a high-refresh monitor, Medium at 368 FPS or High at 260 FPS offers a balance of visual quality and speed, while Ultra at 247 FPS still exceeds most display capabilities. At 2560x1440, Medium provides 232 FPS with a min of 197 FPS, which is ideal for smooth gameplay, while High at 164 FPS and Ultra at 156 FPS are also viable. At 3840x2160, Medium delivers 121 FPS with a min of 103 FPS, making it the recommended preset for 4K gamers who want a stable experience above 100 FPS. Ultra at 82 FPS is playable but may dip below 60 FPS on some scenes, though no min FPS was recorded. Low at 4K (171 FPS) is unnecessary unless maximizing frame rate is the sole priority. The data suggests Medium is the sweet spot for 4K, while High or Ultra are optimal for 1440p and 1080p.

Measured FPS Breakdown

At 1920x1080, the measured averages are: Low 496 FPS, Medium 368 FPS (min 313, max 423), High 260 FPS, and Ultra 247 FPS. The spread between Low and Ultra is 249 FPS, showing a significant impact from settings.

At 2560x1440, the averages are: Low 328 FPS, Medium 232 FPS (min 197, max 267), High 164 FPS, and Ultra 156 FPS. The gap from Low to Ultra is 172 FPS, with the Medium preset maintaining a strong min FPS above 190.

At 3840x2160, the averages are: Low 171 FPS, Medium 121 FPS (min 103, max 140), High 86 FPS, and Ultra 82 FPS. The difference between Low and Ultra is 89 FPS. The Medium preset is the only 4K setting with recorded min/max values, showing a floor of 103 FPS.

The data shows a consistent pattern: at each resolution, the jump from Low to Medium reduces FPS by roughly 25-29%, from Medium to High by another 20-29%, and from High to Ultra by a smaller 2-5% margin. This suggests diminishing returns on Ultra settings, particularly at 4K where the difference between High (86 FPS) and Ultra (82 FPS) is only 4 FPS.
