Pc Building Simulator

Pc Building Simulator’s benchmark data for the AMD Ryzen 5 3600 paired with the AMD Radeon RX 7900 XT shows a configuration that is heavily GPU-limited at high resolutions but reveals a more balanced profile as resolution drops. The measured rows span three resolutions and four settings presets, providing a clear picture of how this pairing behaves under varying loads. The data indicates that the RX 7900 XT’s substantial memory bandwidth and compute resources dominate the frame rate equation at 4K, while the Ryzen 5 3600’s six cores and twelve threads become increasingly relevant at 1080p. This analysis breaks down the settings hierarchy, the GPU’s role, resolution scaling behavior, exact FPS measurements, the combo’s rank among tested configurations, and the CPU’s contribution, all strictly from the provided fact pack.

Settings Recommendations

The measured data makes a compelling case for the High preset as the optimal experience across all three resolutions. At 3840x2160, High produces an average of 65.7 FPS, which is 2.2 FPS higher than Ultra’s 63.5 FPS, while Low and Medium deliver 129 and 92.2 FPS respectively. The jump from High to Ultra yields a negligible gain in visual fidelity for a measurable performance cost—the 65.7 to 63.5 delta represents a 3.3% drop, which is not worth the marginal quality increase. At 2560x1440, High averages 127.3 FPS, comfortably above the 60 FPS threshold and only 5.9 FPS behind Ultra’s 121.4 FPS, but with a 4.6% performance penalty that High avoids. The 1080p data reinforces this pattern: High sits at 201.1 FPS, while Ultra drops to 189.5 FPS, a 5.8% reduction for what is typically a subtle difference in shadow and texture filtering quality.

Medium settings deserve consideration for users prioritizing higher frame rates without sacrificing too much visual polish. At 4K, Medium’s 92.2 FPS is 40.3% faster than High’s 65.7 FPS, making it the best choice for high-refresh-rate 4K displays. At 1440p, Medium’s 175.9 FPS versus High’s 127.3 FPS represents a 38.2% improvement, which could be decisive for 144Hz monitors. Low settings are only recommended for extreme frame rate chasing, as they produce 255.7 FPS at 1080p and 218.3 FPS at 1440p, but the visual compromises are typically severe in a simulation title where reading small text and UI elements matters. The data suggests High provides the best balance of image quality and performance, with Medium as a strong fallback for high-refresh-rate scenarios.

GPU Role

The AMD Radeon RX 7900 XT’s specifications explain its dominant role in this game’s results. The GPU features 20 GB of GDDR6 memory on a 320-bit bus, delivering 800.0 GB/s of bandwidth, which is critical for a simulation game that renders dense scenes with many objects and textures. The memory clock runs at 2500 MHz with 20 Gbps effective speed, while the GPU’s base clock is 1387 MHz, boost clock is 2394 MHz, and game clock is 2025 MHz. The 5376 shading units, 336 texture mapping units, and 192 raster operations pipelines provide the raw compute needed to push high frame rates, with a pixel rate of 459.6 GPixel/s and texture rate of 804.4 GTexel/s.

The GPU’s FP32 performance of 51.48 TFLOPS and FP16 of 103.0 TFLOPS (2:1) indicate substantial parallel processing capability, which aligns with the measured FPS results showing the GPU as the primary bottleneck at 4K. The 300 W TDP and dual-slot design suggest this is a high-power component, and the 2x 8-pin power connectors point to a card that requires robust power delivery. The RX 7900 XT’s 82nd percentile ranking among all GPUs in the benchmark database, with an average benchmark score of 38358, places it well above the median, and its nearest rivals—the NVIDIA GeForce RTX 5080 Mobile (deltaPct 0) and NVIDIA CMP 70HX (deltaPct 0.3)—show it is competitive with top-tier mobile and mining variants. The GPU’s role is clearly to provide headroom at lower resolutions, but at 4K, its performance ceiling is still high enough to keep frame rates playable even on Ultra.

Resolution Scaling

The FPS data reveals a steep scaling curve as resolution increases, which is a hallmark of GPU-bound workloads. From 1920x1080 to 2560x1440, the average FPS drops by 36.7% on High settings, from 201.1 to 127.3. The 1440p to 4K transition on High shows a further 48.4% reduction, from 127.3 to 65.7 FPS. This compounding drop—roughly half the frame rate lost at each step—indicates that the RX 7900 XT’s rendering load scales nearly linearly with pixel count, which is expected for a simulation game with heavy draw calls and complex geometry.

Low settings exhibit a similar pattern but with less severe drops. At Low, the 1080p score of 255.7 FPS falls to 218.3 at 1440p (a 14.6% reduction) and then to 129 at 4K (a 40.9% reduction from 1440p). This non-linear behavior suggests that at lower settings, the CPU becomes more involved in feeding the GPU, and the Ryzen 5 3600’s capabilities start to matter. At 1080p Low, the system is likely CPU-limited to some degree, as evidenced by the relatively modest FPS gain from Medium (225.5) to Low (255.7) compared to the larger gains at higher resolutions. The data implies that the 1080p results are partially constrained by the CPU’s processing of game logic and simulation updates, while 4K results are purely GPU-bound.

Measured FPS Breakdown

The measured FPS values provide a complete picture of performance across all tested configurations. At 3840x2160, the Ultra preset averages 63.5 FPS, High averages 65.7 FPS, Medium averages 92.2 FPS, and Low averages 129 FPS. The gap between Ultra and High is minimal at 2.2 FPS, but the jump from High to Medium is substantial at 26.5 FPS, indicating that certain settings in the High preset—likely shadows or post-processing—have a disproportionate impact on 4K performance.

At 2560x1440, the data shows Ultra at 121.4 FPS, High at 127.3 FPS, Medium at 175.9 FPS, and Low at 218.3 FPS. The Medium-to-Low gain of 42.4 FPS is significant, while the High-to-Ultra difference of 5.9 FPS is minor. This resolution is where the setup’s sweet spot lies, with High achieving over 120 FPS and Low exceeding 200 FPS, making it ideal for high-refresh-rate gaming. At 1920x1080, the scores are Ultra at 189.5 FPS, High at 201.1 FPS, Medium at 225.5 FPS, and Low at 255.7 FPS. The 1080p results show diminishing returns from lowering settings—the gap from High to Low is only 54.6 FPS, whereas at 4K the same settings range spans 65.5 FPS, confirming that the CPU is starting to cap performance at this resolution.

How This Combo Ranks

CPU Role

The AMD Ryzen 5 3600’s specifications provide context for its role in this pairing. With 6 cores and 12 threads, a base clock of 3.60 GHz, and boost clock of 4.20 GHz, this Zen 2 architecture processor (codename Matisse) on the 7 nm process offers solid multi-threaded performance for a simulation game that likely utilizes multiple threads for physics, AI, and building logic. The 32 MB shared L3 cache and 51.2 GB/s memory bandwidth (DDR4, dual-channel) are adequate but not exceptional, and the CPU’s 65 W TDP indicates efficient operation. The benchmark scores show strong multi-threaded capability—Cinebench R23 multicore scores 15045, while single-core scores 2124—but the PassMark single-thread score of 2562 suggests less impressive single-thread performance, which can impact games that rely heavily on one or two threads.

The CPU’s percentileVsAllCpus of 76 and average benchmark score of 18129 place it just below the Intel Core i5-11400 (18150, deltaPct -0.1) in the nearest rivals list, indicating it is competitive with newer mid-range parts but not a top-tier performer. The 1080p FPS data reveals the CPU’s limiting effect: at Low settings, the system reaches 255.7 FPS, which is high but not extraordinarily so for a GPU like the RX 7900 XT, suggesting the CPU cannot feed the GPU fast enough to exceed this threshold. The 3dmark scores further illustrate this—single-thread score is 696, while max-thread score is 4603, showing a significant scaling efficiency but a relatively low per-core ceiling. In a simulation game where frame pacing depends on consistent CPU frame times, the Ryzen 5 3600’s older architecture may introduce occasional hitches at very high frame rates, but the data shows no such issues in the averaged FPS measurements. The CPU’s role is to provide adequate processing power for game logic while relying on the GPU for most of the rendering work, and this division of labor works well at 1440p and 4K but becomes strained at 1080p.
