A: Yes, at 1080p with Low settings the average FPS is 117.6, and at Medium settings it drops to 85.1. High settings yield 58.2 FPS, while Ultra averages 54.9 FPS—all playable, though Ultra sits close to the 60 FPS threshold.

Q: How does the RX 580 compare to its nearest GPU rivals in raw benchmark scores?

A: The RX 580's average benchmark score is 13559, placing it within 0.1% of the NVIDIA GeForce GTX 950 (13549) and exactly tied with the NVIDIA GeForce GTX 570 (13564). It is 1.1% ahead of the AMD Radeon Pro 455 (13416) and 1.1% behind the NVIDIA P106-090 (13716).

Q: What is the CPU's performance standing relative to other processors?

A: The Ryzen 7 7700X has an average benchmark score of 34313, which is 0.4% higher than the Intel Core i5-13500 (34175) and 0.5% higher than the Intel Core i7-12800HX (34136). It trails the Intel Core Ultra 7 165H and AMD EPYC 4244P by 0.8% each (34584 and 34599 respectively).

Q: Is the RX 580's 8 GB VRAM sufficient for this game?

A: The RX 580 comes with 8 GB of GDDR5 memory on a 256-bit bus with 256.0 GB/s bandwidth. Given that the game runs at 18.1 FPS at 4K High settings, the memory capacity is not the limiting factor—raw compute power is.

Q: What kind of CPU workload does Pc Building Simulator present?

A: The Ryzen 7 7700X scores 30325 in Cinebench R23 multicore and 4281 in single-core. Its PassMark multithread score is 35686, while single-thread is 4190. The game's modest demands mean these scores are rarely stressed, as evidenced by the GPU-bound frame rates.

Q: How does resolution scaling affect the performance gap between Low and Ultra settings?

A: At 1080p, the gap between Low (117.6 FPS) and Ultra (54.9 FPS) is 62.7 FPS. At 1440p, the same spread is 43.8 FPS (78.1 vs 34.3). By 4K, the gap narrows to 23.3 FPS (42.2 vs 19.8), showing diminishing returns as the GPU saturates.

GPU Role

The AMD Radeon RX 580, built on the Polaris 20 chip with GCN 4.0 architecture, operates at a base clock of 1257 MHz and boost clock of 1340 MHz. Its 8 GB of GDDR5 memory runs at 2000 MHz (8 Gbps effective) across a 256-bit bus, providing 256.0 GB/s of bandwidth. 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.

In Pc Building Simulator, the RX 580's role is decisive. The measured FPS at 1080p High (58.2) drops by 38.1% at 1440p (36.0), and further by 49.7% at 4K (18.1). This steep scaling curve is characteristic of a GPU that runs out of compute throughput as pixel count rises. The GPU's PassMark G3D score of 8813 and compute score of 3488 reflect its mid-pack standing—it ranks in the 53rd percentile among all GPUs. Its FP32 performance of 6.175 TFLOPS is modest by modern standards.

The RX 580's DirectX 12 PassMark score of 43 is notably lower than its DirectX 11 score of 60, suggesting that the older API path may be more efficient on this architecture. This can matter in a game like Pc Building Simulator, which likely doesn't stress modern rendering features. The GPU's Vulkan score of 45173 and OpenCL score of 37453 in Geekbench indicate reasonable compute capability, but the game's reliance on traditional rasterization means these numbers don't translate to higher frame rates.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent across all settings. At Low settings, the RX 580 delivers 117.6 FPS at 1080p, which falls to 78.1 FPS at 1440p (−33.6%) and 42.2 FPS at 4K (−64.1%). Medium settings show a similar pattern: 85.1 FPS at 1080p, 54.6 at 1440p (−35.8%), and 29.1 at 4K (−65.8%). High settings yield 58.2, 36.0 (−38.1%), and 18.1 (−68.9%) respectively.

The Ultra setting reveals the most dramatic scaling: 54.9 FPS at 1080p, 34.3 at 1440p (−37.5%), and 19.8 at 4K (−63.9%). These percentage drops are remarkably consistent—typically 34-38% from 1080p to 1440p, then another 50-53% from 1440p to 4K. This linear scaling pattern is a textbook sign of a GPU-bound scenario. If the CPU were the bottleneck, the frame rates would compress as resolution increases, because the CPU's workload doesn't scale with pixel count.

The data indicates that even at 1080p Ultra, the RX 580 is working near its limits. The 54.9 FPS result at 1080p Ultra versus 117.6 at 1080p Low shows a 53.3% performance hit from settings alone, confirming that the GPU's shading and texture units are the primary constraint. The Ryzen 7 7700X, with its 8 cores and 16 threads boosting to 5.40 GHz, is not the limiting component in any resolution tested.

Measured FPS Breakdown

At 1920x1080, the RX 580 delivers its best results. Low settings produce an average of 117.6 FPS, making for a highly playable experience. Medium settings drop to 85.1 FPS, still well above the 60 FPS target. High settings achieve 58.2 FPS, while Ultra settings yield 54.9 FPS—both playable but with occasional dips likely in busy scenes.

Moving to 2560x1440, the GPU's limitations become apparent. Low settings still manage 78.1 FPS, but Medium falls to 54.6, High to 36.0, and Ultra to 34.3. The gap between Medium and Low at 1440p is 23.5 FPS, while the gap between Ultra and High is only 1.7 FPS—suggesting that beyond High settings, the GPU is hitting a hard compute ceiling.

At 3840x2160, the RX 580 struggles across the board. Low settings average 42.2 FPS, Medium 29.1, High 18.1, and Ultra 19.8. Notably, Ultra slightly outperforms High at 4K (19.8 vs 18.1), a statistical anomaly that could reflect driver-level optimizations or the game's specific workload at those settings. The 4K results are uniformly below 30 FPS except for Low, making this resolution impractical for smooth gameplay with this GPU.

The scaling from 1080p Low to 4K Low shows a 64.1% reduction in frame rate, while the same resolution jump at Ultra settings shows a 63.9% reduction. This consistency reinforces that the GPU's raw throughput, not memory bandwidth or CPU, governs performance. The RX 580's 256.0 GB/s bandwidth is adequate for 8 GB of GDDR5 at these resolutions, but the 6.175 TFLOPS FP32 compute is insufficient for higher pixel counts.

How This Combo Ranks

This combination ranks 1654th out of 1769 tested combos in Pc Building Simulator, placing it in the bottom 6.5% of configurations. This low ranking is almost entirely attributable to the RX 580, which sits in the 53rd percentile among all GPUs—essentially the median GPU. The Ryzen 7 7700X, by contrast, ranks in the 89th percentile among all CPUs, making it a top-tier processor.

The mismatch is stark: a CPU that outperforms 89% of its peers paired with a GPU that outperforms only 53% of its peers. In a simulation game like Pc Building Simulator, where the visual rendering demands are not extreme, this pairing yields mediocre results. The rank of 1654 out of 1769 suggests that most other combinations tested—even those with weaker CPUs but stronger GPUs—deliver better frame rates in this title.

The GPU's nearest rivals in benchmark scores are telling. The NVIDIA GeForce GTX 570 (13564) and GTX 950 (13549) are essentially performance equals to the RX 580, differing by less than 0.1%. This places the RX 580 squarely in the mid-range GPU category of its era, and its end-of-life production status confirms that it is not competitive with modern offerings. For Pc Building Simulator specifically, the combo rank reflects that this GPU cannot keep up with the CPU's potential.

CPU Role

The AMD Ryzen 7 7700X is a Zen 4 architecture processor built on a 5 nm process by TSMC, featuring 8 cores and 16 threads. Its base clock of 4.50 GHz boosts to 5.40 GHz, and it supports DDR5 memory via a dual-channel bus with 83.2 GB/s bandwidth. The CPU's 32 MB of shared L3 cache and 1 MB L2 per core provide ample memory hierarchy for gaming workloads.

In Pc Building Simulator, the CPU's role is largely supportive. The game's simulation logic is not demanding enough to stress the Ryzen 7 7700X's capabilities—its Cinebench R23 multicore score of 30325 and single-core score of 4281 are far beyond what this title requires. The PassMark multithread score of 35686 and single-thread score of 4190 reinforce that this CPU has massive headroom in this game.

The data confirms the CPU is not the bottleneck. If the Ryzen 7 7700X were limiting performance, we would expect frame rates to plateau across resolutions rather than scale linearly with pixel count. Instead, the RX 580's compute limitations drive the results. The CPU's 3DMark scores—8859 for 16 threads, 8852 for max threads, and 1090 for single thread—show strong multi-threaded performance that the game simply doesn't exploit.

The nearest rival comparison is instructive: the Ryzen 7 7700X is within 0.8% of the Intel Core Ultra 7 165H and AMD EPYC 4244P in average benchmark score, and within 0.5% of the Intel Core i7-12800HX. This places it among the top performers in its class, yet the RX 580 drags the overall combo down. For a game like Pc Building Simulator, the CPU's 8 cores and 16 threads are more than sufficient; the GPU is the limiting factor in every resolution and settings combination tested.
