# Pc Building Simulator — Intel Core i7-12700K + AMD Radeon RX 580

The Intel Core i7-12700K paired with the AMD Radeon RX 580 produces a distinctly GPU-limited experience in Pc Building Simulator, with the CPU's substantial headroom visible only at lower resolutions and settings. The measured frame rates across 1080p, 1440p, and 4K reveal a system whose performance ceiling is dictated almost entirely by the Polaris 20 GPU. At 1080p Low, the combo achieves 120.5 FPS, but this drops to 20.2 FPS at 4K Ultra — a 83.2% reduction that underscores the GPU's limitations under heavy load. The data indicates that while the i7-12700K is capable of feeding the RX 580 at 1080p, the GPU saturates quickly as resolution and settings scale upward.

Resolution Scaling

The FPS degradation from 1080p to 4K follows a steep curve that clearly isolates the RX 580 as the bottleneck. At Low settings, the average frame rate falls from 120.5 FPS at 1920x1080 to 78.9 FPS at 2560x1440 (a 34.5% drop), then to 43.1 FPS at 3840x2160 (a further 45.4% drop from 1440p). This pattern — where each resolution step costs roughly a third to nearly half of the remaining performance — is characteristic of a GPU that is running out of pixel throughput and memory bandwidth. The RX 580's 256.0 GB/s bandwidth and 32 ROPs are simply insufficient for 4K workloads, even at minimal settings.

At High settings, the scaling is even more punishing. The transition from 1080p (62.7 FPS) to 1440p (38.2 FPS) represents a 39.1% reduction, while moving to 4K (21.2 FPS) costs another 44.5%. The Ultra preset tells a similar story: 57.1 FPS at 1080p, 33.6 FPS at 1440p, and 20.2 FPS at 4K. The fact that 4K High and 4K Ultra produce nearly identical results (21.2 vs 20.2 FPS) suggests that the GPU is completely saturated at this resolution — additional settings changes yield diminishing returns because the render pipeline is already maxed out.

The 1080p-to-4K delta at each setting tier is revealing. Low settings see a 77.4 FPS absolute drop (120.5 to 43.1), High sees a 41.5 FPS drop, Medium sees a 59.4 FPS drop (87.0 to 27.6), and Ultra sees a 36.9 FPS drop. The larger absolute drop at Low settings indicates that when the GPU is not heavily loaded by effects, the resolution scaling has more room to expose the raw pixel-fill limitations. Conversely, at Ultra, the GPU is already struggling at 1080p, so the additional resolution burden has less absolute impact.

This data strongly indicates that the limiting component at 1440p and 4K is the RX 580. The i7-12700K, with its 12 cores and 20 threads, shows no signs of being the constraint — a conclusion supported by the fact that even at 1080p Low (the most CPU-favorable scenario), the frame rate of 120.5 FPS is well below what this processor is capable of delivering in less GPU-bound titles. The system is balanced only at 1080p Medium and above, where the GPU's 8 GB GDDR5 memory and 2304 shading units become the primary determinants of performance.

FAQ

Q: What is the maximum average frame rate this combo achieves in Pc Building Simulator?

GPU Role

The AMD Radeon RX 580 is the decisive component in this pairing, and its specifications explain the measured results. The GPU operates with a base clock of 1257 MHz and a boost clock of 1340 MHz, paired with 8 GB of GDDR5 memory on a 256-bit bus. The memory runs at 2000 MHz (8 Gbps effective), yielding a bandwidth of 256.0 GB/s. These figures are modest by modern standards, and the data confirms that they become the limiting factor as resolution increases.

The GPU's 2304 shading units, 144 texture mapping units, and 32 ROPs deliver a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s. The FP32 performance of 6.175 TFLOPS (with FP16 at the same 1:1 ratio) places this GPU in the mid-range of the database's tested hardware. Its percentileVsAllGpus of 53 indicates that it sits almost exactly at the median of all GPUs in the benchmark database, which is consistent with the observed frame rates — playable at 1080p, marginal at 1440p, and inadequate at 4K.

The memory configuration is particularly relevant for Pc Building Simulator. The 8 GB VRAM is not exhausted at any of the tested settings (the game is not VRAM-intensive in the measured scenarios), but the 256-bit bus and 256.0 GB/s bandwidth are the physical constraints that limit fill-rate-bound scenarios. At 4K, the pixel throughput requirement exceeds what the RX 580 can deliver, resulting in the 20-43 FPS range observed across all settings.

The GPU's DirectX 12 (12_0) and Vulkan 1.3 API support are adequate for this 2019 simulation title. However, the Polaris 20 chip, built on 14 nm with 5,700 million transistors at 232 mm², does not have the architectural efficiency of newer designs. The measured FPS data shows that the GPU's performance ceiling is reached well before the CPU's potential is tapped — the i7-12700K's 3.60 GHz base and 5.00 GHz boost clocks are never the constraint in this game.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average of 120.5 FPS, which is the only configuration exceeding 100 FPS in the entire data set. Medium settings yield 87.0 FPS, High settings drop to 62.7 FPS, and Ultra bottoms out at 57.1 FPS. The gap between Low and Medium (33.5 FPS) is larger than the gap between High and Ultra (5.6 FPS), suggesting that the Medium preset introduces a significant portion of the visual effects that tax the GPU, while the jump from High to Ultra has diminishing performance costs.

Moving to 2560x1440, the frame rates become more constrained. Low settings average 78.9 FPS, which is still smooth but represents a 34.5% drop from the 1080p Low result. Medium settings fall to 54.8 FPS, High to 38.2 FPS, and Ultra to 33.6 FPS. The 1440p Ultra result of 33.6 FPS is notable — it is only 66.5% of the 1080p Ultra figure, showing that the resolution increase alone costs one-third of the performance even at the highest settings.

At 3840x2160, the RX 580 is clearly overwhelmed. Low settings manage 43.1 FPS, which is the only 4K result above 40 FPS. Medium drops to 27.6 FPS, High to 21.2 FPS, and Ultra to 20.2 FPS. The differences between High and Ultra at 4K (1.0 FPS) and between 1440p Ultra and 4K Ultra (13.4 FPS) illustrate the severe pixel-fill bottleneck. The 4K Ultra result of 20.2 FPS is below the 24 FPS threshold typically considered the minimum for cinematic frame rates, making this configuration unsuitable for 4K gaming in this title.

The settings scaling at each resolution follows a consistent pattern: Low is always approximately 1.4x faster than Medium, Medium is roughly 1.4-1.6x faster than High, and High is only slightly faster than Ultra. The one outlier is 1080p, where the Low-to-Medium gap (33.5 FPS) is disproportionately large compared to the High-to-Ultra gap (5.6 FPS), indicating that at lower resolutions the CPU can still push high frame rates until the GPU reaches its architectural limits.

How This Combo Ranks

This configuration of Intel Core i7-12700K and AMD Radeon RX 580 ranks 1621 out of 1769 tested combos in Pc Building Simulator, placing it in the bottom 8.4% of the database. This low ranking is driven almost entirely by the GPU, as the CPU is a high-performing part in isolation. The i7-12700K's avgBenchmarkScore of 35684 puts it in the 89th percentile of all CPUs, with nearest rivals including the AMD Ryzen 7 PRO 5845 (35802, deltaPct -0.3%) and Intel Core i7-13700T (35468, deltaPct 0.6%). The CPU's 3dmark scores range from 1043 (single thread) to 9979 (max threads), and its Cinebench R23 multicore score of 29241 confirms strong multi-threaded capability.

In contrast, the RX 580's avgBenchmarkScore of 13559 places it in the 53rd percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce GTX 570 (13564, deltaPct 0%), NVIDIA GeForce GTX 950 (13549, deltaPct 0.1%), AMD Radeon Pro 455 (13416, deltaPct 1.1%), and NVIDIA P106-090 (13716, deltaPct -1.1%). All four rivals are within 1.1% of the RX 580's score, confirming that this GPU is clustered tightly with other mid-range parts from its generation.

The combination of an elite CPU with a mediocre GPU creates a significant imbalance. The i7-12700K could drive a much more powerful GPU without bottlenecking, but the RX 580 limits the system to the frame rates documented above. The combo's rank of 1621 reflects this mismatch — there are 148 combos in the database that perform worse, but the vast majority of tested configurations (1768 total) achieve better results in this game. For a simulation title like Pc Building Simulator, which is not particularly demanding on either component, the ranking suggests that most other hardware pairings tested in this database deliver smoother gameplay than this specific combination.
