# Pc Building Simulator — Intel Core i5-10400F + AMD Radeon RX 7900 XTX

This combo ranks 454th out of 1,769 tested combinations in Pc Building Simulator, placing it in the top quarter of all systems evaluated. The pairing of a 10th-gen Intel six-core processor with AMD's flagship RDNA 3 graphics card produces a system that delivers high frame rates across most settings, though the data reveals interesting scaling patterns that suggest the CPU becomes a limiting factor at lower resolutions while the GPU dominates at 4K.

How This Combo Ranks

The 454th position out of 1,769 combos represents a solidly above-median result, but the ranking doesn't tell the full story about where this system's strengths and weaknesses lie. The CPU itself sits at the 73rd percentile among all processors, with an average benchmark score of 14,168. Its nearest rivals in the synthetic benchmark data include the AMD EPYC 7552 (scoring 14,115, just 0.4% behind), the AMD Ryzen 3 7320C (14,277, -0.8% ahead), the Intel Core i5-8500 (14,332, -1.1% ahead), and the AMD Ryzen Embedded V2546 (14,336, -1.2% ahead). This clustering within roughly one percent indicates the i5-10400F delivers performance consistent with its class, neither significantly outpacing nor falling behind comparable processors.

The GPU, meanwhile, achieves the 85th percentile among all graphics cards, with an average benchmark score of 44,019. Its nearest rivals are notably close: the AMD Radeon Pro 580 (44,195, -0.4% ahead), the NVIDIA GeForce RTX 4090 Mobile (43,667, 0.8% behind), the NVIDIA Quadro M6000 (43,313, 1.6% behind), and the NVIDIA GeForce RTX 4070 Ti (44,900, -2% ahead). This tight grouping around the 44,000 mark suggests the RX 7900 XTX delivers competitive raw compute performance within its peer group, though the game's actual frame rates will reveal how that translates to real-world playability.

In the context of Pc Building Simulator specifically, the combination's mid-pack ranking (454 of 1,769) reflects a system that's clearly capable, but the measured frame rates show that the CPU is holding back the GPU's potential in several scenarios — particularly at 1080p where the processor's six cores become the bottleneck.

GPU Role

The AMD Radeon RX 7900 XTX brings substantial hardware to this pairing: 24 GB of GDDR6 memory on a 384-bit bus delivers 960.0 GB/s of bandwidth, while the Navi 31 chip (built on a 5 nm process with 57,700 million transistors across a 529 mm² die) provides 6,144 shading units, 384 texture mapping units, and 192 raster operations units. The GPU's clock speeds are aggressive — a base of 1929 MHz, a game clock of 2365 MHz, and a boost of 2498 MHz — with memory running at 2500 MHz (effectively 20 Gbps).

These specifications translate into a GPU that scores 31,238 in Passmark G3D and 17689 in Passmark GPU Compute, with a 3DMark Steel Nomad DX12 score of 6,841. The pixel rate of 479.6 GPixel/s and texture rate of 959.2 GTexel/s are the theoretical maxima; the measured FPS data shows how these translate in practice.

In Pc Building Simulator, the GPU's role becomes most apparent at 4K resolution. At 3840x2160 with Ultra settings, the combo averages 64.9 FPS — just above the 60 FPS threshold for smooth gameplay. Dropping to High settings at the same resolution yields 67.7 FPS, a modest improvement of only about 4%. The jump to Medium settings produces 98.2 FPS, and Low settings nearly double that at 137.9 FPS. This scaling pattern indicates the GPU is the primary constraint at 4K, with settings changes having a significant impact on frame rates.

The 24 GB frame buffer is far more than Pc Building Simulator requires, but the memory bandwidth of 960.0 GB/s ensures that texture streaming and scene complexity never stall the rendering pipeline. The GPU's DirectX 12 Ultimate support (with a 12_2 feature level) aligns well with the game's requirements, though the simulation genre rarely pushes graphical effects to the extent that would fully utilize the RX 7900 XTX's capabilities.

CPU Role

The Intel Core i5-10400F provides six cores and twelve threads, with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. Built on Intel's 14 nm Comet Lake architecture, this processor features 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 12 MB of shared L3 cache. Memory support is DDR4 with dual-channel configuration providing 42.7 GB/s of bandwidth. The processor's synthetic benchmark results include a Cinebench R23 multi-core score of 10,297 and single-core score of 1,453, with Geekbench scores of 5,783 (multi-core) and 1,454 (single-core).

The CPU's percentile ranking of 73 places it comfortably above average, but its six-core configuration becomes a limiting factor in Pc Building Simulator at lower resolutions. The measured FPS data shows this clearly: at 1920x1080 with Low settings, the combo reaches 258.9 FPS, but Ultra settings at the same resolution drop to 195 FPS. This gap of about 33% between Low and Ultra at 1080p is smaller than what a GPU-bound system would typically show, indicating the CPU is preventing the GPU from reaching even higher frame rates.

The processor's 3DMark thread scaling scores — 688 for single-thread, 1,350 for 2-threads, 2,560 for 4-threads, 3,929 for 8-threads, and 4,735 for max threads — show diminishing returns beyond 8 threads. This pattern suggests the game's simulation logic benefits from multiple cores but doesn't scale perfectly to all twelve threads. The Passmark multi-thread score of 12,115 and physics score of 696 provide additional context: the CPU handles physics calculations adequately, but the relatively modest single-thread performance (Passmark single-thread score of 2,541) becomes more relevant at high frame rates where per-frame CPU work dominates.

Measured FPS Breakdown

At 3840x2160, the combo delivers 67.7 FPS on High settings, 137.9 FPS on Low, 98.2 FPS on Medium, and 64.9 FPS on Ultra. The 4K Ultra result is the lowest across all tested configurations, but still maintains playability. The scaling from Ultra to Low at 4K shows a 2.1x improvement (from 64.9 to 137.9 FPS), demonstrating that the GPU has substantial headroom when graphical load is reduced.

Moving to 2560x1440, performance improves markedly: High settings produce 134.9 FPS, Low reaches 219.1 FPS, Medium achieves 190.1 FPS, and Ultra delivers 130 FPS. The gap between Ultra and High at 1440p is only about 4% (130 vs. 134.9 FPS), suggesting diminishing returns from the highest settings tier. The jump from High to Medium at this resolution is more substantial at 41% (190.1 vs. 134.9), indicating Medium represents a sweet spot for visual quality versus performance.

At 1920x1080, the combo reaches its peak performance: 198.1 FPS on High, 258.9 FPS on Low, 224.6 FPS on Medium, and 195 FPS on Ultra. Notably, the difference between High and Ultra at 1080p is minimal (1.6%), while the gap between Low and Medium is 13% (258.9 vs. 224.6). The 1080p Low result of 258.9 FPS represents the highest measured frame rate across all configurations, but the relative compression between settings at this resolution (from 195 to 258.9 FPS, or 1.33x scaling) compared to 4K (2.1x scaling) confirms that the CPU is increasingly the bottleneck as resolution decreases.
