# Pc Building Simulator with Intel Core Ultra 7 265K + NVIDIA GeForce RTX 5090 D

Pc Building Simulator, a simulation title from 2019, presents an unusual workload pattern where the Intel Core Ultra 7 265K and NVIDIA GeForce RTX 5090 D combination delivers a rank of 2 out of 3002 tested combos, placing it in the 99.9th percentile of all configurations. The measured frame rates across three resolutions and four settings reveal a system that is heavily GPU-bound at lower settings but transitions to a more balanced profile as resolution and quality increase, with the CPU's 20 cores and 5.50 GHz boost clock proving more than sufficient for the game's simulation logic while the GPU's 32 GB of VRAM and 1.79 TB/s bandwidth handle the visual load.

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

The Intel Core Ultra 7 265K brings 20 cores and 20 threads from the Arrow Lake architecture, built on a 3 nm process by TSMC with 17,800 million transistors. Its base clock of 3.90 GHz and boost clock of 5.50 GHz, combined with 30 MB of shared L3 cache and 102.4 GB/s dual-channel DDR5 memory bandwidth, position it as a high-end desktop part. In Pc Building Simulator, the CPU's role is primarily to manage the simulation's logic, component compatibility calculations, and system boot sequences — tasks that benefit from high single-thread performance. The PassMark single-thread score of 4928 and Cinebench R23 single-core score of 2020 indicate strong per-core capability, which is critical for a game that simulates real-time PC building interactions.

The CPU's 20-thread configuration is notable because Pc Building Simulator's simulation loop, while not heavily multithreaded, does spawn background tasks for component thermal modeling and power draw calculations. The Cinebench R23 multicore score of 35850 suggests that even if the game were to utilize multiple threads, the headroom is substantial. At 1080p Low settings, the system achieves 496 FPS, which is likely near the CPU's practical limit for frame generation in this title, but the data shows the CPU is not a bottleneck at any tested configuration. The 94th percentile ranking against all CPUs, with nearest rivals including the Intel Xeon 6511P (-0.2% delta) and Intel Core i7-14700KF (+1% delta), confirms that the 265K sits at the top tier of desktop processors.

The L3 cache structure — 30 MB shared across all cores — provides ample capacity for the game's asset management, though Pc Building Simulator's modest system requirements mean the CPU rarely stretches beyond its capabilities. The integrated Arc Xe-LPG Graphics 64EU is present but irrelevant for this discrete GPU configuration. With a TDP of 125 W, the CPU's power envelope is modest for a 20-core part, allowing sustained boost clocks without thermal throttling in most chassis setups, which is relevant for a game that rewards stable frame times during complex build simulations.

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

The NVIDIA GeForce RTX 5090 D, built on the Blackwell 2.0 architecture with the GB202 chip, is a formidable GPU with 21,760 shading units, 680 texture mapping units, and 176 raster output units. Its 32 GB of GDDR7 memory on a 512-bit bus delivers 1.79 TB/s of bandwidth, which is excessive for Pc Building Simulator's relatively simple visuals but ensures no memory-related stutters regardless of resolution or settings. The base clock of 2017 MHz and boost clock of 2407 MHz, producing 104.8 TFLOPS of FP32 compute, drive the high frame rates observed across all test scenarios.

In Pc Building Simulator, the GPU's role is less about rendering complex 3D scenes and more about displaying the user interface, component models, and case interiors with smoothness. The measured frame rates show the GPU is fully capable of pushing 496 FPS at 1080p Low, but the more interesting data points come at higher settings where the GPU's resources are engaged more thoroughly. The 3DMark Steel Nomad DX12 score of 14326 and PassMark G3D score of 44065 indicate the GPU's raw performance, but the game's engine appears to scale with both resolution and settings in a predictable manner.

The GPU's 92nd percentile ranking against all GPUs places it near the top, though the nearest rivals — AMD Radeon RX 6650M XT (+1.1% delta), AMD Radeon RX 6850M XT (-1.6% delta), and two NVIDIA Tesla P100 variants (-2.1% and -2.4% deltas) — are a mix of mobile and datacenter parts, suggesting the RTX 5090 D's benchmark profile is unique. The 1750 MHz memory clock (28 Gbps effective) and 423.6 GPixel/s pixel rate provide ample fill rate for the game's resolution scaling, and the 575 W TDP with a suggested 950 W PSU indicates this is a power-hungry component that demands serious system planning — a fitting detail for a game about building PCs.

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

The resolution scaling data reveals a clear pattern of GPU-bound behavior at lower resolutions transitioning to a more balanced workload at 4K. At Low settings, frame rates drop from 496 FPS at 1080p to 358 FPS at 1440p (a 27.8% reduction) and further to 187 FPS at 4K (a 47.8% reduction from 1440p). This steep decline indicates the GPU is the primary limiter even at Low settings, as the CPU's 20 threads and high boost clock are not the constraining factor. The 4K Low result of 187 FPS still exceeds the refresh rate of most monitors, showing the system's capability.

At Medium settings, the pattern continues: 402 FPS at 1080p, 254 FPS at 1440p (a 36.8% drop), and 133 FPS at 4K (a 47.6% drop from 1440p). The scaling factor between 1080p and 4K is roughly 3x at Medium settings (402 to 133), which aligns with the pixel count difference of 3.7x, indicating the GPU is handling the increased load efficiently. The High settings show 284 FPS at 1080p, 179 FPS at 1440p, and 94 FPS at 4K, with the 1080p-to-4K scaling factor of 3.02x. Ultra settings produce 270 FPS at 1080p, 171 FPS at 1440p, and 89 FPS at 4K, with a 3.03x scaling factor.

The consistency of the scaling factors across settings — all around 3x from 1080p to 4K — strongly suggests the GPU is the limiting component at all tested configurations. If the CPU were the bottleneck, we would expect diminishing returns as resolution increases, with frame rates converging. Instead, the linear scaling with pixel count indicates the RTX 5090 D's compute and memory resources are being fully utilized, and the Core Ultra 7 265K is never the constraint. The 4K Ultra result of 89 FPS, while lower than lower settings, remains playable, and the data suggests that even at the highest quality setting, the system maintains smooth performance for a simulation game.

How This Combo Ranks — use comboRankInGame vs other tested combos

This combination of Intel Core Ultra 7 265K and NVIDIA GeForce RTX 5090 D ranks 2nd out of 3002 tested combos in Pc Building Simulator, placing it in the top 0.07% of all configurations. This exceptional ranking is driven by the combination's ability to maintain high frame rates across all resolutions and settings, with even the most demanding scenario (4K Ultra) achieving 89 FPS. The rank of 2 indicates that only one other combination outperforms this setup, which is remarkable given the game's 2019 release date and the relatively modest graphical demands of the simulation genre.

The CPU's 94th percentile ranking and the GPU's 92nd percentile ranking individually place them near the top of their respective categories, but the combination achieves a much higher relative position in this specific game. This suggests that Pc Building Simulator rewards a balanced pairing of a high-end CPU with a flagship GPU, even though the game does not heavily stress either component. The nearest CPU rivals — Intel Xeon 6511P (-0.2%), Intel Xeon Platinum 8270 (-0.7%), Intel Core i7-14700KF (+1%), and AMD Ryzen 7 9700F (+1.3%) — show that the 265K is competitive but not dominant in synthetic benchmarks, yet the real-world game performance is what matters here.

The GPU's nearest rivals, including AMD Radeon RX 6650M XT and RX 6850M XT, are notably different classes of hardware (mobile GPUs), which highlights the RTX 5090 D's unique position in the benchmark database. The delta percentages of -1.6% to +1.1% indicate that the RTX 5090 D's average benchmark score is within a narrow range of these rivals, but in Pc Building Simulator specifically, the combination's rank of 2 demonstrates that the game responds well to this particular hardware pairing. The data suggests that for simulation games with moderate graphical demands, having a top-tier CPU and GPU ensures maximum frame rates, but the marginal benefit of the highest-end components is limited once the game's engine caps performance.

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

Analyzing the measured FPS rows, the Medium settings at all resolutions offer the best balance between visual quality and performance. At 1080p Medium, the system achieves 402 FPS with a minimum of 342 FPS and maximum of 462 FPS, providing a substantial frame rate cushion above any display's refresh rate. The High settings at 1080p reduce performance to 284 FPS, and Ultra drops to 270 FPS — differences that are unlikely to be perceptible on most monitors but represent a measurable reduction in frame rate. Medium at 1440p delivers 254 FPS (minimum 216 FPS, maximum 292 FPS), which remains above 240 Hz refresh rate displays, making it the recommended choice for high-refresh-rate gaming.

At 4K, Medium settings produce 133 FPS with a minimum of 113 FPS and maximum of 153 FPS, which is ideal for 120 Hz displays but may not fully utilize 144 Hz or higher refresh rate panels. High settings at 4K drop to 94 FPS, and Ultra to 89 FPS, which are still playable but begin to approach the threshold where frame time consistency matters. The data shows that the step from Medium to High at any resolution costs approximately 25-30% of frame rate, while the step from High to Ultra costs only 5-10%, suggesting diminishing returns for the Ultra preset. For the best experience, Medium settings provide the highest frame rates while maintaining visual fidelity, and the 113 FPS minimum at 4K Medium ensures no noticeable stuttering.

The Low settings, while achieving the highest frame rates (496 FPS at 1080p, 358 FPS at 1440p, 187 FPS at 4K), sacrifice too much visual quality for a game that involves inspecting component details. Ultra settings, conversely, offer marginal visual improvements over High but at a significant frame rate cost. Given that the game is a simulation where smooth camera movement and responsive UI interactions are more important than ultra-realistic textures, Medium settings at any resolution represent the sweet spot. The measured data supports this recommendation: Medium settings consistently deliver frame rates that are 1.5-2x higher than Ultra while likely providing comparable visual clarity for the game's interface-driven gameplay.

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

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings achieve an average of 496 FPS, while Medium reaches 402 FPS with a minimum of 342 FPS and maximum of 462 FPS. High settings produce 284 FPS, and Ultra settings yield 270 FPS. The scaling from Low to Ultra shows a 45.6% reduction in frame rate, indicating that even the most demanding settings at 1080p leave substantial performance headroom. The minimum FPS at Medium (342 FPS) is still higher than the average FPS at Ultra (270 FPS), highlighting the performance cost of the Ultra preset.

At 2560x1440, the pattern shifts with a more pronounced impact from settings changes. Low settings average 358 FPS, Medium averages 254 FPS (minimum 216 FPS, maximum 292 FPS), High averages 179 FPS, and Ultra averages 171 FPS. The reduction from 1080p to 1440p ranges from 27.8% (Low) to 36.8% (Medium) to 37% (High) to 36.7% (Ultra). The High and Ultra settings are nearly identical (179 vs 171 FPS), suggesting that the Ultra preset's additional visual effects have minimal impact at this resolution. The Medium preset's minimum of 216 FPS ensures compatibility with 200 Hz displays, while High and Ultra dip below 180 FPS.

At 3840x2160, the frame rates become more moderate but remain playable. Low settings average 187 FPS, Medium averages 133 FPS (minimum 113 FPS, maximum 153 FPS), High averages 94 FPS, and Ultra averages 89 FPS. The 4K resolution imposes a 62.3% reduction from 1080p at Low settings, 66.9% at Medium, 66.9% at High, and 67% at Ultra. The consistency of this reduction across settings reinforces the GPU-bound nature of the workload. The Medium preset at 4K, with its 113 FPS minimum, is the only setting that maintains triple-digit frame rates, while High and Ultra fall below 100 FPS. The data clearly shows that 4K gaming with this combination is best served by Medium settings, as the visual improvement from Higher presets does not justify the 30-40 FPS loss.
