# Pc Building Simulator: AMD Ryzen 5 7600 + AMD Radeon RX 6650 XT

The AMD Ryzen 5 7600 paired with the AMD Radeon RX 6650 XT delivers a solid 1080p experience in Pc Building Simulator, with the data showing a clear transition from CPU-bound to GPU-bound behavior as resolution climbs. This combination lands at rank 1144 out of 1769 tested combos, placing it in the lower-middle portion of the database, yet the measured frames tell a story of consistent playability across most settings. The CPU, a 6-core/12-thread Zen 4 part with a 5.10 GHz boost clock, posts an average benchmark score of 26617, sitting at the 83rd percentile of all CPUs. The GPU, built on RDNA 2.0 with 8 GB of GDDR6 memory on a 128-bit bus, achieves a 72nd percentile ranking with an average score of 29024. Together, they form a balanced pairing that shows measurable strengths at lower resolutions and predictable degradation at 4K.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but not uniform across settings, revealing where the bottleneck shifts. At Low settings, the average frame rate falls from 233.9 FPS at 1920x1080 to 150.8 FPS at 2560x1440, then plunges to 76.2 FPS at 3840x2160. That represents a 35.5% reduction from 1080p to 1440p, and a further 49.5% drop from 1440p to 4K. The scaling pattern suggests that at Low settings, the CPU is doing substantial work at 1080p, but by 4K the GPU becomes the limiting factor. At Medium settings, the progression is 167.7 FPS at 1080p, 102.4 FPS at 1440p, and 57.2 FPS at 4K—a 38.9% decline from 1080p to 1440p and a 44.1% decline from 1440p to 4K. High settings show 114.9 FPS at 1080p, 73.6 FPS at 1440p, and 39.2 FPS at 4K, with the 1440p-to-4K drop reaching 46.7%. Ultra settings follow a similar trajectory: 109.8 FPS at 1080p, 69.6 FPS at 1440p, and 37.6 FPS at 4K, a 46.0% reduction between the latter two resolutions.

The consistent pattern across all settings—where the 1440p-to-4K drop is always larger than the 1080p-to-1440p drop—indicates that the RX 6650 XT's compute and memory bandwidth are the primary constraints at higher resolutions. The GPU's 280.3 GB/s memory bandwidth and 10.79 TFLOPS of FP32 performance are simply insufficient to maintain frame rates as pixel count quadruples. The CPU, with its 32 MB of L3 cache and 83.2 GB/s memory bandwidth, shows it can feed the GPU adequately at 1080p, but the data suggests that at 4K, even the Low preset's 76.2 FPS is achieved with significant headroom on the processor side. This is a classic case of resolution scaling exposing the graphics card as the limiting component, particularly when comparing the 1080p Low result of 233.9 FPS—a number that implies the CPU could push even higher if the GPU weren't capping output.

GPU Role

The Radeon RX 6650 XT operates with a base clock of 2055 MHz and a boost clock of 2635 MHz, with a game clock rated at 2410 MHz. Its 8 GB of GDDR6 memory runs at 2190 MHz, delivering 17.5 Gbps effective and a bandwidth of 280.3 GB/s across a 128-bit bus. These specifications directly influence the measured results in Pc Building Simulator, a game that appears to be sensitive to both memory bandwidth and raw shading throughput. The GPU's 2048 shading units and 64 ROPs produce a pixel rate of 168.6 GPixel/s and a texture rate of 337.3 GTexel/s, which explains why the card performs admirably at 1080p but struggles to maintain 60 FPS at 4K on higher presets.

At 3840x2160, the Ultra preset yields 37.6 FPS, and High yields 39.2 FPS—both below the 40 FPS mark, indicating that the GPU is overwhelmed by the fill-rate demands of 4K rendering. Medium at 4K reaches 57.2 FPS, which is playable but not smooth, while Low at 4K achieves 76.2 FPS, suggesting that reducing texture and shading complexity allows the card to keep up. The 8 GB VRAM capacity is not directly measured as a limiting factor in these results, but the data shows that the card's memory subsystem—with its relatively narrow 128-bit bus—becomes a bottleneck at higher resolutions and quality settings. The GPU's percentile ranking of 72 places it near the AMD Radeon RX 6800M (deltaPct 0) and AMD Radeon RX 470 (deltaPct 0.1), while sitting slightly below the Intel Arc A370M (deltaPct -0.5) and AMD Radeon RX Vega M GH (deltaPct -0.6). These rival comparisons, based on average benchmark scores, indicate that the RX 6650 XT is a mid-range performer that excels in lighter workloads but cannot sustain high frame rates under heavy pixel loads.

How This Combo Ranks

The combo ranks 1144 out of 1769 tested combinations, placing it in the 35th percentile of all CPU-GPU pairings in this game. This rank reflects the overall balance of the system: the Ryzen 5 7600 is a strong processor with a 83rd percentile standing among all CPUs, while the RX 6650 XT sits at the 72nd percentile among GPUs. The discrepancy between CPU and GPU percentiles suggests that the graphics card is the weaker link in this pairing, which is consistent with the resolution scaling data. The CPU's nearest rivals in benchmark scores include the AMD Ryzen 7 5800X3D (deltaPct 0.2), Intel Core i9-12900HK (deltaPct -0.2), AMD EPYC 8024P (deltaPct 0.2), and Intel Core i9-11900K (deltaPct 0.3)—all within a narrow 0.5% band of the Ryzen 5 7600's average score of 26617. This tight clustering indicates that the CPU is not the limiting factor; any of these processors would likely produce similar results in Pc Building Simulator when paired with the same GPU.

The GPU's rivals show even closer scores, with the RX 6800M (deltaPct 0), RX 470 (deltaPct 0.1), Arc A370M (deltaPct -0.5), and RX Vega M GH (deltaPct -0.6) all within 0.6% of the RX 6650 XT's average of 29024. This near-identical performance band means that swapping the GPU for any of these alternatives would yield negligible differences in benchmark scores, and likely in actual gameplay as well. The combo's rank of 1144 out of 1769 reflects that while this system is far from the top of the database, it is also not at the bottom—it sits in the middle of a large field of combinations, many of which feature more powerful GPUs. The data shows that this pairing is well-matched for 1080p gaming, where the CPU can stretch its legs, but it becomes GPU-limited at higher resolutions, which drags down its overall standing in the rankings.

Settings Recommendations

Based on the measured frame rates, the optimal experience depends on the target resolution and desired smoothness. At 1920x1080, the Ultra preset delivers 109.8 FPS, which is well above the 60 FPS threshold and close to the 114.9 FPS of High settings. The difference between High and Ultra at 1080p is only 4.4%, meaning that Ultra is essentially free in performance terms—there is no reason to drop below it for a smoother experience, as the 233.9 FPS of Low is far beyond what most displays can show. At 2560x1440, the High preset achieves 73.6 FPS, while Ultra drops to 69.6 FPS—a 5.4% reduction that may be imperceptible to most users. Medium at 1440p hits 102.4 FPS, but the step from Medium to High is a 28.1% decrease, suggesting that High is the sweet spot for visual fidelity without sacrificing smoothness. At 3840x2160, the situation changes dramatically: only Low (76.2 FPS) and Medium (57.2 FPS) reach playable levels, while High (39.2 FPS) and Ultra (37.6 FPS) fall below the 40 FPS mark. For 4K users, Medium is the recommended preset, as it offers a 45.9% improvement over High while maintaining visual quality above the lowest tier.

The data indicates that the Ultra preset is the best choice at 1080p, High at 1440p, and Medium at 4K. This progression aligns with the GPU's capabilities: at lower resolutions, the card has spare throughput to handle maximum settings, but as pixel count increases, it must trade visual quality for frame rate. The measured FPS differences between settings at each resolution reinforce this recommendation—at 1080p, the spread from Low to Ultra is 124.1 FPS, while at 4K it narrows to 38.6 FPS, showing that the GPU has less headroom to accommodate quality increases at higher resolutions.

Measured FPS Breakdown

At 1920x1080, the average frame rates span from 233.9 FPS on Low to 109.8 FPS on Ultra. Medium hits 167.7 FPS, and High reaches 114.9 FPS. The gap between Low and Medium is 66.2 FPS, while the gap between Medium and High is 52.8 FPS, and High to Ultra is only 5.1 FPS. This pattern shows diminishing returns at the top end—the jump from Low to Medium is substantial, but the step from High to Ultra is negligible in performance terms. At 2560x1440, Low achieves 150.8 FPS, Medium 102.4 FPS, High 73.6 FPS, and Ultra 69.6 FPS. The 1440p results show a more consistent degradation: Low to Medium drops 48.4 FPS, Medium to High drops 28.8 FPS, and High to Ultra drops only 4.0 FPS. At 3840x2160, Low produces 76.2 FPS, Medium 57.2 FPS, High 39.2 FPS, and Ultra 37.6 FPS. The 4K numbers reveal that the GPU is struggling: Low to Medium loses 19.0 FPS, Medium to High loses 18.0 FPS, and High to Ultra loses just 1.6 FPS, indicating that the card is hitting a hard ceiling regardless of settings.

Across all resolutions, the Ultra-to-High delta remains small—between 1.6 and 5.1 FPS—which suggests that the Ultra preset's additional graphical features are not the primary cost; rather, the GPU is constrained by its raw processing power. The FPS data also shows that the CPU is never the bottleneck at any resolution above 1080p, as the frame rates scale consistently with GPU load. For users with a 60 Hz monitor, the system is fully capable at 1080p on any preset, at 1440p on High or below, and at 4K only on Low or Medium. For those targeting 120 FPS, 1080p on Low or Medium is the only viable option, while 1440p on Low barely clears the bar at 150.8 FPS. The measured results provide a clear picture: this combo is a 1080p champion, a competent 1440p performer, and a 4K compromise.
