# Pc Building Simulator: Intel Core Ultra 7 265 + NVIDIA GeForce RTX 5090

The pairing of Intel's Core Ultra 7 265 with NVIDIA's GeForce RTX 5090 produces a fascinating dataset in Pc Building Simulator, revealing a system that scales dramatically across resolutions but shows distinct bottlenecks at each tier. With a combo rank of 38 out of 3,002 tested configurations, this is a top-tier setup, yet the measured FPS numbers tell a story of diminishing returns as pixel counts rise. The 20-core Arrow Lake CPU and the 32 GB GDDR7 Blackwell GPU each take turns being the limiting factor, depending on where you look in the resolution and settings matrix.

Resolution Scaling

The resolution scaling behavior here is textbook GPU-bound scaling, but with a twist. At 1080p Low, the system delivers 473 FPS, which drops to 336 FPS at 1440p Low (a 29% reduction) and further to 176 FPS at 4K Low (a 48% reduction from 1440p). This pattern indicates that even at Low settings, the RTX 5090's rendering workload scales significantly with pixel count, though the CPU is clearly capable of feeding enough frames at 1080p to keep the GPU busy.

Moving to High settings, the scaling is more linear: 266 FPS at 1080p, 168 FPS at 1440p (a 37% drop), and 88 FPS at 4K (a 48% drop from 1440p). The 4K High result of 88 FPS suggests that at this resolution, the GPU is the primary limiter — the RTX 5090's 104.8 TFLOPS of FP32 compute and 1.79 TB/s memory bandwidth are being fully utilized, but the game's simulation engine likely imposes additional overhead that prevents higher frame rates.

The most telling data point is the Ultra preset scaling. At 1080p Ultra, the system hits 253 FPS. At 1440p Ultra, it drops to 160 FPS (a 37% reduction), and at 4K Ultra, it falls to 84 FPS (a 48% reduction from 1440p). This consistent ~37-48% scaling factor across all settings suggests that the RTX 5090's performance in this game scales predictably with resolution, but the absolute numbers at 4K are surprisingly modest for a flagship GPU. The 4K Ultra result of 84 FPS is only slightly above the 60 FPS threshold, implying that Pc Building Simulator's simulation logic, not raw graphics, is what keeps the frame rate from soaring higher.

Settings Recommendations

The measured data offers a clear hierarchy of performance-per-setting-tier. At 1080p, the jump from Low (473 FPS) to Medium (377 FPS) costs 20% performance, while Medium to High (266 FPS) costs another 29%. High to Ultra (253 FPS) is nearly free at just 5% — this suggests that Ultra at 1080p is the optimal choice, as the visual upgrade from High to Ultra barely impacts frame rate while presumably adding significant graphical fidelity.

At 1440p, the story is similar but with tighter margins. Low delivers 336 FPS, Medium 238 FPS, High 168 FPS, and Ultra 160 FPS. The High-to-Ultra gap is again minimal at 5%, making Ultra the sensible pick for anyone with a 1440p display. The 160 FPS at 1440p Ultra is well above the typical high-refresh threshold, so there is no reason to drop below Ultra for competitive play.

At 4K, the calculus changes. Low yields 176 FPS, Medium 124 FPS (with a minimum of 106 FPS), High 88 FPS, and Ultra 84 FPS. The Medium preset at 4K shows the only measured minimum FPS in the dataset (106 FPS), which suggests a degree of frame-time variance that could be perceptible. Given that 4K Ultra (84 FPS) is only 4 FPS slower than 4K High (88 FPS), the Ultra preset is again the better value — but players targeting a locked 60 FPS experience will find both acceptable. The data implies that this combo can run Ultra at any resolution without dipping below playable territory, though 4K Ultra's 84 FPS average leaves little headroom for demanding scenes.

GPU Role

The RTX 5090's specifications explain much of its behavior in this game. With 32 GB of GDDR7 memory on a 512-bit bus, the card has a massive 1.79 TB/s of bandwidth — more than enough to feed Pc Building Simulator's texture and asset streaming needs at any resolution. The 2,407 MHz boost clock and 21,760 shading units produce a theoretical 104.8 TFLOPS of FP32 compute, which is the kind of raw throughput that should crush most simulation titles.

Yet the benchmark data shows the RTX 5090 trailing its own average performance profile. The GPU's 3DMark Steel Nomad DX12 score of 18,355 and Passmark G3D score of 39,650 place it in the 92nd percentile of all GPUs, but its nearest rivals in the average benchmark score list include the NVIDIA Tesla P100 PCIe 16 GB (0.3% faster) and AMD Radeon RX 6850M XT (1.1% faster) — both far older or lower-tier parts. This suggests that Pc Building Simulator does not stress the RTX 5090's unique capabilities, such as its 170 RT cores or 680 tensor cores, which remain largely idle in a game that is more about system simulation than ray-traced visuals.

The VRAM capacity is effectively a non-factor here; 32 GB is overkill for a game that likely uses a fraction of that at 4K. The card's 1,636.8 GTexel/s texture rate and 423.6 GPixel/s pixel rate are more relevant to the resolution scaling seen in the data — at 4K, the GPU is pixel-bound, which explains why FPS drops roughly 48% from 1440p to 4K across all settings. The GPU's 575 W TDP and PCIe 5.0 x16 interface are adequate for this workload, but the benchmark results indicate the game's engine is not designed to exploit the full parallel throughput of Blackwell 2.0 architecture.

How This Combo Ranks

The combo rank of 38 out of 3,002 tested combinations places this system in the top 1.3% of all configurations tested. This is an elite standing, but the specific rank relative to the CPU's and GPU's individual percentiles (93rd and 92nd, respectively) reveals a subtle mismatch. The system is performing at a level consistent with its components, yet the fact that it is not higher — given that both parts are near the top of their respective charts — suggests that Pc Building Simulator's simulation engine creates a bottleneck that no amount of GPU or CPU compute can fully eliminate.

Consider the CPU's nearest rivals: the AMD EPYC 4464P (0.3% faster average benchmark score) and the Intel Core Ultra 7 265F (0.3% slower) are essentially performance twins. The GPU's rivals include the Tesla P100 PCIe 16 GB (0.3% faster) and the Radeon Pro Vega 64X (1.4% slower), which are data-center and workstation parts, not gaming GPUs. This implies that the RTX 5090's gaming-specific features (like its 4th-gen tensor cores) are not being leveraged in this title, and the combo's rank is likely driven more by the CPU's strong single-threaded performance (5,960 in Cinebench R23 single-core) than the GPU's raw compute.

The rank of 38 suggests there are 37 other combos that outperform this pairing in Pc Building Simulator. Given the GPU's near-flagship status, those superior combos likely feature even faster CPUs (possibly with higher single-thread scores) or optimizations in clock speeds that this game's engine favors. The data shows that this combo is excellent, but not the absolute best — a fact that aligns with the CPU being in the 93rd percentile rather than the 99th.

CPU Role

The Intel Core Ultra 7 265 presents an interesting case for Pc Building Simulator. With 20 cores and 20 threads (no hyperthreading), a base clock of 2.40 GHz, and a boost clock of 5.30 GHz, this Arrow Lake-S chip offers a blend of high single-thread and strong multi-thread performance. Its Cinebench R23 scores of 42,216 multi-core and 5,960 single-core place it in the 93rd percentile of all CPUs, with an average benchmark score of 64,640.

The CPU's role in this game becomes clearer when examining the FPS data at 1080p. At Low settings, the system hits 473 FPS — a number that is almost certainly CPU-limited, as the RTX 5090 could render far more frames if the CPU could feed it. The 20 cores and 20 threads handle the game's simulation logic (tracking PC components, temperatures, and system compatibility) alongside the rendering thread, and the 5.30 GHz boost clock ensures that the main game thread never stalls. The Passmark single-thread score of 4,689 and multi-thread score of 49,682 both support this: the CPU is strong enough to push frame rates into the 400+ range at low graphical loads.

However, the CPU's memory bandwidth of 102.4 GB/s (dual-channel DDR5) could be a limiting factor at these extreme frame rates. At 1080p Low, the game must update the simulation state each frame, and with 20 threads available, the memory subsystem is likely the bottleneck. The 30 MB of shared L3 cache helps, but it cannot fully compensate for the dual-channel memory bus when the GPU is capable of outputting frames faster than the CPU can process game state. This explains why 1080p Low (473 FPS) does not scale proportionally to 1080p Medium (377 FPS) — the CPU is working harder at Medium due to more objects, but the GPU is still not the limit.

At 4K, the CPU's role diminishes. The 88 FPS at 4K High is GPU-bound, as evidenced by the near-linear scaling from 1440p High (168 FPS) to 4K High (88 FPS). The CPU's 20 cores are more than sufficient to handle the simulation at 4K, where the GPU's pixel throughput is the deciding factor. This duality — CPU-bound at 1080p Low, GPU-bound at 4K High — is the defining characteristic of this combo.

Measured FPS Breakdown

At 1920x1080, the system delivers 473 FPS on Low, 377 FPS on Medium (with a 320-433 FPS range), 266 FPS on High, and 253 FPS on Ultra. The Medium preset's minimum of 320 FPS is notable, as it represents a 15% drop from the average, suggesting occasional simulation hitches even at this resolution.

At 2560x1440, the figures are 336 FPS on Low, 238 FPS on Medium (202-274 FPS range), 168 FPS on High, and 160 FPS on Ultra. The Medium preset's 36 FPS spread between minimum and maximum indicates more frame-time variance than at 1080p, but the average remains solidly high.

At 3840x2160, the results are 176 FPS on Low, 124 FPS on Medium (106-143 FPS range), 88 FPS on High, and 84 FPS on Ultra. This is the only resolution where the Medium preset shows a minimum FPS (106) that could dip below 100, and the 88 FPS at High is the lowest average in the dataset. The 4K Ultra result of 84 FPS is only 4 FPS below the High preset, indicating that the Ultra settings add negligible GPU load in this game — likely because it is simulation-bound rather than geometry-bound.

The progression from Low to Ultra at each resolution shows diminishing returns: at 1080p, the drop from Low to Ultra is 46%; at 1440p, it is 52%; at 4K, it is 52%. This consistency suggests that the game's graphics settings primarily affect GPU load, while the CPU-side simulation cost remains constant regardless of preset.
