Pc Building Simulator

# How This Combo Ranks

The Intel Core Ultra 9 275HX paired with the NVIDIA GeForce RTX 4090 lands at rank 598 out of 3,002 tested combos in Pc Building Simulator. That places this combination in the top 20% of all tested systems, which is a strong showing for a mobile processor paired with a flagship desktop GPU. The rank suggests that while this setup is far from the absolute top, it sits comfortably above the vast majority of configurations tested for this simulation title.

What makes this ranking particularly interesting is the nature of the components themselves. The Core Ultra 9 275HX is a mobile processor, with a 55 W TDP and a 3 nm process node, while the RTX 4090 is a desktop-class GPU with a 450 W TDP and a 5 nm node. The data shows that this hybrid combination—mobile CPU with desktop GPU—still manages to outperform roughly 80% of all tested combos, which speaks to both the capability of the Ultra 9 275HX and the raw power of the RTX 4090.

Looking at the CPU's benchmark percentile, the Ultra 9 275HX sits at the 94th percentile among all CPUs, with an average benchmark score of 67,469. Its nearest rivals in the CPU benchmark database include the Intel Xeon w5-3525 (deltaPct -0.3%), AMD EPYC 4484PX (deltaPct -0.5%), AMD Ryzen Threadripper PRO 5955WX (deltaPct -0.6%), and Intel Xeon 6515P (deltaPct 0.7%). These are all workstation-class processors, which contextualizes the mobile Ultra 9's standing—it's competing with far larger, higher-power parts and essentially matching them within a single percentage point.

For the GPU, the RTX 4090 holds the 88th percentile among all GPUs, with an average benchmark score of 60,347. Its nearest rivals include the Intel Arc Pro A60 (deltaPct 0%), AMD Radeon Pro Vega 48 (deltaPct 0.3%), AMD Radeon Pro W6600M (deltaPct -2.5%), and AMD Radeon PRO V710 (deltaPct 2.9%). The fact that the RTX 4090 sits in the 88th percentile despite being an end-of-life product from 2022 suggests newer GPUs have pushed past it, but it remains a formidable performer in this simulation context.

The combo rank of 598 out of 3,002 represents a nuanced picture: the CPU is exceptional for its class, the GPU is very strong but no longer the absolute top, and together they produce a system that is clearly capable but not the ultimate Pc Building Simulator machine. The data indicates that this combination would serve most users exceptionally well, with headroom for high settings at most resolutions.

GPU Role

The NVIDIA GeForce RTX 4090 brings substantial resources to Pc Building Simulator. Its 24 GB of GDDR6X memory on a 384-bit bus provides 1.01 TB/s of bandwidth, which is an enormous amount for a simulation game that likely involves rendering complex PC components and cases. The GPU's memory clock runs at 1313 MHz, translating to 21 Gbps effective, and the core clocks are 2235 MHz base and 2520 MHz boost.

The RTX 4090's architecture, Ada Lovelace, includes 16,384 shading units, 512 texture mapping units, and 176 raster operation pipelines. It also features 128 ray tracing cores and 512 tensor cores, though a simulation title like Pc Building Simulator is unlikely to heavily utilize ray tracing or tensor operations. The raw rasterization throughput is what matters most here, with a pixel rate of 443.5 GPixel/s and a texture rate of 1,290.2 GTexel/s. The FP32 performance of 82.58 TFLOPS gives the GPU plenty of compute headroom for any physics or simulation calculations the game might throw at it.

In the context of Pc Building Simulator, the GPU's role appears to be the primary driver of frame rates at higher resolutions. The measured FPS data shows a clear pattern: at 1080p, the CPU has enough headroom to push FPS very high, but at 4K, the GPU becomes the limiting factor. This is consistent with the GPU's design as a high-resolution rasterization powerhouse, though the data suggests that even this flagship GPU struggles to maintain ultra-settings frame rates at 4K in this title.

The GPU's benchmark results reinforce its standing: a Passmark G3D score of 38,194, a 3DMark Steel Nomad DX12 score of 9,223, and Geekbench OpenCL and Vulkan scores of 255,416 and 271,631 respectively. These numbers indicate strong DirectX 12 and Vulkan performance, which aligns with the game's likely rendering API. The Passmark DirectX 11 score of 326 and DirectX 12 score of 150 are harder to interpret without context, but the GPU compute score of 26,613 suggests substantial parallel processing capability.

Resolution Scaling

The measured FPS data reveals a distinct scaling pattern across resolutions. Starting at 1920x1080, the combo achieves 370 FPS on Low settings, which drops to 262 FPS on Medium, 185 FPS on High, and 176 FPS on Ultra. Moving to 2560x1440, the numbers fall to 233 FPS on Low, 165 FPS on Medium, 117 FPS on High, and 111 FPS on Ultra. At 3840x2160, the frame rates decline further to 122 FPS on Low, 86 FPS on Medium, 61 FPS on High, and 58 FPS on Ultra.

The scaling from 1080p to 1440p shows roughly a 37% reduction in FPS across most settings, which is a typical resolution scaling penalty. However, the jump from 1440p to 4K is more dramatic: Low settings drop from 233 to 122 FPS (a 48% reduction), Medium from 165 to 86 FPS (48% reduction), High from 117 to 61 FPS (48% reduction), and Ultra from 111 to 58 FPS (48% reduction). This consistent ~48% drop across all settings from 1440p to 4K strongly indicates that the GPU is the limiting factor at higher resolutions.

The data suggests that at 1080p, the system is heavily CPU-bound or at least balanced, since the Ultra 9 275HX's 24 cores and 24 threads can feed the RTX 4090 enough data to reach frame rates as high as 370 FPS on Low. At 4K, however, the GPU's pixel throughput becomes the bottleneck, as even the RTX 4090's 443.5 GPixel/s pixel rate can't sustain the highest frame rates. The 4K Ultra result of 58 FPS is particularly telling—it's barely above the 60 FPS threshold commonly considered smooth, suggesting that users wanting 4K Ultra would need to make compromises.

Interestingly, the resolution scaling pattern is remarkably consistent across all four settings levels, which implies that the game's settings don't dramatically change the balance between CPU and GPU load. The 48% drop from 1440p to 4K is nearly identical whether on Low or Ultra, suggesting that Pc Building Simulator's rendering workload scales uniformly with resolution regardless of quality presets.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 370 FPS, which is exceptionally high and indicates the system has massive headroom at this resolution. Medium settings yield 262 FPS on average, with a minimum of 222 FPS and a maximum of 301 FPS—the only settings level in the entire dataset that provides min/max values. High settings drop to 185 FPS, while Ultra settings produce 176 FPS. The gap between High and Ultra at 1080p is only 9 FPS (about 5%), suggesting that the Ultra preset adds visual quality without a proportional performance cost at this resolution.

Moving to 2560x1440, the frame rates remain very playable. Low settings average 233 FPS, Medium averages 165 FPS with a minimum of 140 FPS and maximum of 190 FPS, High averages 117 FPS, and Ultra averages 111 FPS. The difference between High and Ultra at 1440p is just 6 FPS (about 5%), again showing that the Ultra preset's additional demands are modest at this resolution. All 1440p settings maintain averages above 100 FPS, which is excellent for a simulation game that might involve complex scenes with many on-screen components.

At 3840x2160, the performance picture changes significantly. Low settings average 122 FPS, which remains smooth. Medium settings average 86 FPS, with a minimum of 73 FPS and maximum of 99 FPS—the consistent minimum above 70 FPS suggests acceptable frame pacing even in demanding scenes. High settings average 61 FPS, which is right at the edge of smoothness for many users. Ultra settings average 58 FPS, dipping below the 60 FPS threshold. The 4K results show that while the combo can handle 4K, users targeting 60+ FPS will need to use Medium settings or lower.

The data reveals an interesting pattern: the gap between Low and Ultra at each resolution is substantial but consistent. At 1080p, the spread is 370 to 176 FPS (a 210% range); at 1440p, it's 233 to 111 FPS (a 210% range); at 4K, it's 122 to 58 FPS (a 210% range). This consistency suggests that the settings presets scale the GPU workload proportionally regardless of resolution, and that the RTX 4090's relative performance across settings is predictable.

Settings Recommendations

The measured FPS data provides clear guidance for optimal settings at each resolution. At 3840x2160, the Ultra preset averages 58 FPS, which is below the 60 FPS threshold. High settings at 4K average 61 FPS, barely crossing that line, but Medium settings at 86 FPS offer substantially more headroom with a minimum of 73 FPS. For 4K users, Medium is the recommended preset—it provides a comfortable margin above 60 FPS while the visual difference from High is likely minimal in a simulation game.

At 2560x1440, all four presets exceed 100 FPS on average. Ultra at 111 FPS is the best choice here, as the 6 FPS difference from High (117 FPS) is negligible but the visual quality improvement is worth it. The minimum FPS on Medium is 140, which indicates strong frame pacing, and Ultra's lack of min/max data doesn't suggest any issues given the high average.

At 1920x1080, the system has enormous headroom. Ultra at 176 FPS is entirely playable, and even Low at 370 FPS is overkill for any display. The recommendation is Ultra at 1080p, as the performance cost from High is only 9 FPS (about 5%) but the visual quality gain is meaningful.

Across all resolutions, the gap between High and Ultra is consistently small (5-6%), making Ultra the preferred choice wherever the frame rate remains acceptable. The only exception is 4K, where Ultra's 58 FPS average might cause stutter on some displays; Medium at 86 FPS is the safer pick there. The data suggests that this combo is powerful enough to run Pc Building Simulator at High or Ultra settings at 1440p without concern, and at Medium for 4K.

CPU Role

The Intel Core Ultra 9 275HX is a 24-core, 24-thread mobile processor based on the Arrow Lake architecture, built on a 3 nm process by TSMC. It has a base clock of 2.70 GHz and a boost clock of 5.40 GHz, with a 55 W TDP. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache. The CPU supports DDR5 memory on a dual-channel bus with 102.4 GB/s bandwidth, and its integrated Arc Xe-LPG Graphics 64EU provides a fallback display solution.

In Pc Building Simulator, the CPU's role is evident from the 1080p performance. At Low settings, the system reaches 370 FPS, which is far beyond what any display can show, indicating that the CPU can feed the RTX 4090 without bottlenecking at lower resolutions. The 24 cores and 24 threads are particularly relevant for a simulation game, which often involves managing multiple systems, components, and physics calculations simultaneously. The 36 MB of L3 cache provides ample fast memory for game state data.

The CPU's benchmark results are impressive for a mobile part. Its Cinebench R23 multicore score is 35,589, and its single-core score is 2,204. Geekbench results show 20,795 multicore and 2,458 single-core. Passmark scores include 55,759 for multithread performance, 191,186 for floating point math, and 155,218 for integer math. The data compression score of 608,381 and encryption score of 47,112 suggest strong general-purpose compute capability.

The Ultra 9 275HX's percentile ranking of 94 among all CPUs, with an average benchmark score of 67,469, places it in elite company. Its nearest rivals are all server or workstation processors, which typically have much higher power envelopes. The fact that this mobile CPU matches them within 0.7% is remarkable. In the context of Pc Building Simulator, the CPU's high single-thread performance (2,204 in Cinebench R23 single-core) is likely crucial, as simulation games often rely heavily on single-threaded game logic.

The CPU's performance at 1080p, where the system reaches 370 FPS on Low, suggests it has significant headroom even for high-refresh-rate displays. At 1440p and 4K, the GPU takes over as the primary performance driver, but the CPU's ability to maintain high frame rates at 1080p indicates it is not a limiting factor in this combination. The 24 threads and 3 nm process node provide a strong foundation for both current and future simulation workloads, and the CPU's 94th percentile standing confirms it is a top-tier mobile processor that pairs well with a flagship GPU.
