Pc Building Simulator

This combo places 57th out of 3,723 tested configurations in Pc Building Simulator, putting it in the top 1.5% of all combinations evaluated. That rank is driven by a pairing of an upper-mid-range CPU with a flagship GPU, but the data shows the workload distribution is far from balanced. The Intel Core i5-14600K holds its own as a capable processor, while the NVIDIA GeForce RTX 5090 does the heavy lifting in most scenarios. Benchmarks indicate this is a system built for high-refresh-rate gaming at any resolution, though the CPU becomes a noticeable factor at lower settings where frame rates climb into territory that stresses even the fastest processors.

How This Combo Ranks

The 57th-place finish out of 3,723 combos puts this pairing in the 98.5th percentile of tested systems. That is a strong result, but not the very top tier—a handful of combinations with more balanced or higher-end CPUs outperform it. The rank reflects the sum of both components, and the data suggests the GPU is the primary driver of this positioning. The RTX 5090 sits at the 92nd percentile among all GPUs, while the i5-14600K ranks at the 90th percentile among all CPUs. Neither component is the absolute best in its class, but together they form a cohesive unit that excels in a simulation title like this one.

Relative to the CPU's nearest rivals, the i5-14600K posts an average benchmark score of 48,618. That puts it 0.2% behind the Intel Xeon Gold 5318H (48,698) and 0.3% ahead of the AMD EPYC 4345P (48,470). The gap to the Intel Core Ultra 5 245HX is 0.7% in favor of the i5, while the Core Ultra 5 245 sits 0.8% ahead. These are marginal differences, meaning the CPU choice within this performance band has little impact on the overall combo rank. The GPU, by contrast, shows a wider spread: the RTX 5090's average score of 79,842 trails the AMD Radeon Pro Vega 64X by 1.4% (80,959) but leads the NVIDIA Tesla P100 PCIe 16 GB by 0.3% (79,605) and the Tesla P100 PCIe 12 GB by 0.6% (79,396). The 1.1% edge over the AMD Radeon RX 6850M XT is equally modest. What this means in practice: the combo's high rank comes from having a top-tier GPU rather than an exceptional CPU, and the data shows that swapping the CPU for any of its nearest rivals would barely move the needle.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor from the Raptor Lake Refresh generation, built on Intel's 10 nm process. Its base clock runs at 3.50 GHz and boosts up to 5.30 GHz, with a 125 W TDP. The cache layout includes 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. For a simulation game like Pc Building Simulator, which typically involves managing multiple system components and calculating compatibility, the CPU's multi-threaded performance matters more than raw single-core speed.

Benchmark data supports this. The CPU scores 24,491 in Cinebench R23 multi-core and 2,064 in single-core, a ratio of roughly 12:1 that highlights strong scaling across its 14 cores. PassMark multithread score of 38,682 and integer math score of 125,737 reinforce the CPU's ability to handle parallel workloads. The data compression score of 482,020 is particularly relevant for a game that might involve file transfers or system imaging tasks. In the measured FPS results, the CPU becomes the limiting factor primarily at 1080p with Low settings, where the frame rate hits 430 FPS—a figure that demands high per-core throughput and low latency. At 4K Ultra, the CPU's role diminishes, as the GPU takes over the bottleneck.

The i5-14600K supports DDR4 and DDR5 memory over a dual-channel bus, and it includes integrated UHD Graphics 770, though the discrete RTX 5090 makes that irrelevant in this configuration. Its 90th percentile ranking among all CPUs places it firmly in the upper echelon, but the nearest rival comparisons show it's not a standout—it's simply a solid, well-rounded processor that doesn't hold back the GPU in most scenarios.

GPU Role

The NVIDIA GeForce RTX 5090 is a Blackwell 2.0 architecture GPU built on TSMC's 5 nm process, with 92,200 million transistors on a 750 mm² die. It comes with 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. The core runs at a base clock of 2017 MHz and boosts to 2407 MHz, with memory clocked at 1750 MHz (28 Gbps effective). The GPU packs 21,760 shading units, 680 TMUs, and 176 ROPs, along with 170 RT cores and 680 tensor cores. Its FP32 throughput is 104.8 TFLOPS, and the pixel rate is 423.6 GPixel/s.

For Pc Building Simulator, the GPU's role is to render the 3D workspace, case models, and component previews. The 32 GB VRAM is overkill for this title, but the raw compute power translates directly to high frame rates. The GPU's benchmark results show a PassMark G3D score of 39,650 and a Geekbench Vulkan score of 376,728, indicating strong DirectX and Vulkan performance. The DirectX 12 score of 185 in PassMark is less impressive, but the 3DMark Steel Nomad DX12 score of 18,355 suggests real-world gaming performance is solid.

The 92nd percentile ranking among all GPUs places it just below the very top tier, and the nearest rival comparisons show it's competitive with workstation-class Tesla parts rather than consumer gaming GPUs. That's a sign of its compute-oriented design, but in this game, the GPU's massive memory bandwidth and shader count ensure it never becomes a bottleneck at any resolution or setting tested.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings levels, providing a clear picture of performance scaling.

1080p: At Low settings, the combo averages 430 FPS. Medium settings drop that to 377 FPS (min 320, max 433), while High settings yield 266 FPS. Ultra settings produce 253 FPS. The 1080p numbers are exceptionally high across the board, with even Ultra settings staying above 250 FPS.

1440p: Low settings average 336 FPS, Medium settings hit 238 FPS (min 202, max 274), High settings reach 168 FPS, and Ultra settings drop to 160 FPS. The step from 1080p to 1440p cuts frame rates by roughly 20-25% at each setting, which is a smaller drop than the resolution increase might suggest.

4K (3840x2160): Low settings average 176 FPS, Medium settings average 124 FPS (min 106, max 143), High settings hit 88 FPS, and Ultra settings fall to 84 FPS. At 4K Ultra, the combo still maintains a playable frame rate, but the gap between Low and Ultra widens significantly compared to lower resolutions.

Across all resolutions, the pattern is consistent: Low and Medium settings deliver high frame rates, while High and Ultra settings impose a more significant penalty. The gap between Medium and High is substantial—at 1440p, it's a 70 FPS drop (238 to 168), and at 4K, it's a 36 FPS drop (124 to 88). The CPU's 20 threads and 5.30 GHz boost clock handle the physics and simulation logic without issue, while the GPU's 32 GB VRAM and 1.79 TB/s bandwidth manage texture loads effortlessly.

Resolution Scaling

The FPS drop from 1080p to 4K reveals where the bottleneck lies. At Low settings, 1080p delivers 430 FPS, which drops to 336 FPS at 1440p (a 22% reduction) and then to 176 FPS at 4K (a 48% reduction from 1440p). At Ultra settings, 1080p yields 253 FPS, 1440p yields 160 FPS (a 37% drop), and 4K yields 84 FPS (a 48% drop from 1440p). The scaling is roughly linear with pixel count, which points to the GPU as the limiting component at higher resolutions.

However, the 1080p Low result of 430 FPS suggests the CPU is nearing its limit there. A perfectly GPU-bound system would show a more dramatic drop from 1080p to 1440p, but the 22% reduction at Low settings is less than the 37% reduction at Ultra. This indicates that at 1080p Low, the CPU is holding the GPU back—the RTX 5090 could push higher frame rates if the i5-14600K could feed it faster. At 4K Ultra, the GPU is clearly the constraint, as the 84 FPS result aligns with the GPU's raw compute limits rather than any CPU deficiency.

The practical takeaway: this combo is GPU-limited at 4K and CPU-limited at 1080p with Low settings. At 1440p, it's a more balanced pairing, with the GPU taking the lead but the CPU still contributing meaningfully. For players targeting 4K, the RTX 5090 is the component to watch; for those chasing maximum frame rates at 1080p, the CPU becomes the bottleneck.

FAQ

Q: Is this combo overkill for Pc Building Simulator?

A: The data shows 430 FPS at 1080p Low and 84 FPS at 4K Ultra, which means the RTX 5090 is underutilized at lower resolutions. At 1080p, the CPU limits performance, so the GPU's full potential isn't reached. At 4K, the GPU is fully engaged, and the frame rates are still high for a simulation title.

Q: Which component is the bottleneck at 4K Ultra?

A: The GPU. At 4K Ultra, the combo produces 84 FPS, and the resolution scaling from 1440p to 4K shows a consistent 48% drop at both Low and Ultra settings, which is characteristic of a GPU-bound scenario. The CPU's role diminishes as resolution increases.

Q: How does the CPU compare to its closest rivals in raw performance?

A: The i5-14600K scores 48,618 on average, which is 0.2% behind the Intel Xeon Gold 5318H (48,698), 0.3% ahead of the AMD EPYC 4345P (48,470), and 0.7% ahead of the Intel Core Ultra 5 245HX (48,287). The Intel Core Ultra 5 245 is 0.8% ahead at 48,995. These are negligible differences in practice.

Q: What's the GPU's performance relative to its nearest rivals?

A: The RTX 5090 scores 79,842 on average. It trails the AMD Radeon Pro Vega 64X by 1.4% (80,959) but leads the NVIDIA Tesla P100 PCIe 16 GB by 0.3% (79,605) and the Tesla P100 PCIe 12 GB by 0.6% (79,396). The AMD Radeon RX 6850M XT is 1.1% behind at 78,940.

Q: What frame rates can I expect at 1440p with High settings?

A: The measured data shows 168 FPS average at 2560x1440 with High settings. This is a comfortable frame rate for high-refresh-rate monitors, and the system has headroom to spare if you lower settings to Medium, which yields 238 FPS.

Q: Does the 32 GB VRAM on the GPU matter for this game?

A: Pc Building Simulator doesn't require that much VRAM, and the data doesn't indicate any VRAM-related performance issues. The 32 GB GDDR7 memory is a feature of the RTX 5090, but the game's performance is driven by compute power rather than memory capacity. The 1.79 TB/s bandwidth helps with texture streaming, but the game itself is not VRAM-intensive.
