Counter-Strike: Global Offensive

The AMD Ryzen 5 3600 and Intel Arc B390 combination delivers playable frame rates across the board in Counter-Strike: Global Offensive, but the data reveals a clear hierarchy: this pairing is heavily CPU-bound at lower resolutions, with the GPU becoming the primary constraint only at 4K Ultra settings. The measured results place this combo in the 2510th position out of 2848 tested configurations, indicating a below-average pairing for this title, yet the actual frame rates remain competitive for the game's fast-paced nature.

Settings Recommendations

The benchmark data shows that the Medium preset offers the best balance of visual quality and performance across all three tested resolutions. At 1080p, Medium produces an average of 258 FPS with a minimum of 219 FPS and a maximum of 296 FPS, according to the measuredFps rows. This represents a significant improvement over High settings, which average 223 FPS, while remaining visually superior to Low settings at 303 FPS. The gap between Medium and Low is only 45 FPS at 1080p, but Medium provides substantially better image quality for that modest performance cost.

At 1440p, the Medium preset averages 177 FPS with a minimum of 151 FPS and a maximum of 204 FPS. This is 23 FPS higher than High settings (154 FPS) and 46 FPS higher than Ultra (131 FPS). The scaling pattern repeats at 4K, where Medium achieves 105 FPS with a minimum of 89 FPS and a maximum of 120 FPS, compared to High's 91 FPS and Ultra's 77 FPS. The Medium preset consistently outperforms High by roughly 14-15% across resolutions, while the jump from Medium to Low yields diminishing returns—only 18 FPS at 1080p, 31 FPS at 1440p, and 18 FPS at 4K.

For competitive play, the data suggests that Low settings at 1080p (303 FPS) provide the maximum headroom for high-refresh-rate monitors, but the Medium preset's 258 FPS average remains sufficient for most displays. The Ultra preset is clearly not recommended, as it drops below 200 FPS at 1080p (190 FPS) and falls to 77 FPS at 4K, which is marginally above the 4K Medium minimum of 89 FPS. The most sensible recommendation is Medium across all resolutions, as it delivers the best compromise between the visual fidelity gains over Low and the substantial performance advantages over High and Ultra.

GPU Role

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture with a 3 nm process node from Intel. Its clock speeds are listed as a base of 300 MHz and a boost of 2500 MHz, with system shared memory operating at system-dependent bandwidth. The GPU features 1536 shading units, 48 texture mapping units, and 24 raster output pipelines, along with 12 ray tracing cores. Its theoretical peak performance is 7.680 TFLOPS for FP32 operations and 15.36 TFLOPS for FP16 (2:1 ratio).

Benchmark results indicate this GPU sits in the 9th percentile of all GPUs, with a 3DMark Steel Nomad DX12 score of 1482. Its nearest rivals in the database are the NVIDIA GeForce GT 520MX (1463, 1.3% faster), NVIDIA GeForce 800M (1460, 1.5% faster), NVIDIA GeForce GT 625 OEM (1446, 2.5% faster), and NVIDIA GeForce GT 710 (1443, 2.7% faster). This places the Arc B390 at the very bottom of the GPU performance spectrum, just above some of the oldest dedicated graphics cards in the database.

In Counter-Strike: Global Offensive, the GPU's role becomes apparent only at higher resolutions and settings. At 1080p, the frame rates are so high (190-303 FPS across settings) that the GPU is not the limiting factor—this is a CPU-bound scenario. The GPU's shared memory architecture and integrated nature mean it relies on system memory bandwidth, which is system-dependent per the specifications. The transition from 1440p to 4K shows the GPU starting to strain: at 4K Ultra, the average drops to 77 FPS, which is 40% lower than 1440p Ultra (131 FPS). The GPU's 24 ROPs and 48 TMUs are modest, but they are sufficient for this older title at 1080p and 1440p, where the frame rates remain well above playable thresholds.

CPU Role

The AMD Ryzen 5 3600 is a 6-core, 12-thread processor from the 3000 series, based on the Zen 2 architecture (Matisse) manufactured on TSMC's 7 nm process. It has a base clock of 3.60 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 32 MB of shared L3 cache. Memory support is DDR4 with dual-channel configuration and 51.2 GB/s bandwidth.

This CPU's benchmark scores show strong multi-threaded performance: Cinebench R23 multicore reaches 15045, while the single-core score is 2124. Geekbench results are 7372 multicore and 1536 single-core. The CPU sits in the 71st percentile of all CPUs, with an average benchmark score of 17035. Its nearest rivals are the Intel Core i7-1260P (17007, 0.2% faster), Intel Core i5-11400 (17067, 0.2% slower), AMD EPYC 7573X (17070, 0.2% slower), and AMD EPYC 7742 (16998, 0.2% faster). These deltaPct values are negligible, indicating the Ryzen 5 3600 is performance-equivalent to these processors in aggregate benchmarks.

In Counter-Strike: Global Offensive, the CPU's 6 cores and 12 threads are more than adequate for the game's engine, which traditionally favors high single-thread performance. The 3DMark 16-thread score of 4605 and single-thread score of 696 indicate the CPU's capability to handle both multi-threaded engine tasks and the critical single-threaded game logic. The evidence for CPU-bound behavior comes from the resolution scaling: at 1080p, frame rates are very high (223 FPS on High), but they do not double when going from 4K to 1080p—they increase by roughly 2.4x, suggesting the CPU is capping performance at lower resolutions. The boost clock of 4.20 GHz is sufficient to drive high frame rates, as evidenced by the 303 FPS at 1080p Low, which is likely near the CPU's maximum output for this game.

How This Combo Ranks

The combination of the AMD Ryzen 5 3600 and Intel Arc B390 ranks 2510 out of 2848 tested combos for Counter-Strike: Global Offensive, placing it in the bottom 12% of all configurations. This low ranking is primarily attributable to the GPU, which ranks in the 9th percentile of all GPUs, whereas the CPU ranks in the 71st percentile of all CPUs. The pairing creates a significant imbalance: the CPU is capable of much higher frame rates than the GPU can deliver at higher resolutions and settings.

This rank of 2510 out of 2848 (with 338 combos ranked lower) indicates that most other tested hardware pairings achieve better performance in this game. However, the actual frame rates are not poor in absolute terms—the combo still delivers 190+ FPS at 1080p across all settings, which would be playable on most monitors. The low rank is a reflection of the GPU's position in the performance hierarchy rather than a failure to achieve playable frame rates. The data suggests that pairing this CPU with a more capable GPU would yield dramatically better results, as the CPU's 71st percentile ranking indicates it has substantial headroom that the Arc B390 cannot utilize.

Resolution Scaling

The measured frame rates show a clear pattern of diminishing returns as resolution decreases. At 1080p Medium, the average is 258 FPS; at 1440p Medium, it drops to 177 FPS (a 31% decrease); and at 4K Medium, it falls to 105 FPS (a 41% decrease from 1440p). This scaling pattern reveals that the system becomes progressively more GPU-bound as resolution increases. The 4K-to-1080p ratio for Medium is 258/105 = 2.46x, which is close to the pixel count ratio of 4K (8.3 megapixels) to 1080p (2.1 megapixels) at 3.97x—indicating that the GPU is not scaling linearly with pixel count, but the CPU is not the sole limiter either.

The most telling evidence comes from the Low settings: at 1080p Low, the average is 303 FPS, while at 4K Low, it is 123 FPS. The 2.46x difference (303/123) is smaller than the pixel count difference, suggesting that even at Low settings, the GPU is starting to become a factor at 4K. Conversely, at 1080p, the difference between Low (303 FPS) and Ultra (190 FPS) is 59%, which indicates the CPU can handle the extra GPU workload without significant frame rate degradation. At 4K, the difference between Low (123 FPS) and Ultra (77 FPS) is 60%, showing the GPU is the dominant constraint at this resolution.

The data indicates that the CPU is the limiting component at 1080p and 1440p, as evidenced by the high frame rates that near the CPU's maximum capability. At 4K, the GPU becomes the bottleneck, particularly at Ultra settings where the average drops to 77 FPS. The system's performance at 1080p is sufficient for competitive play, but the GPU's limitations at 4K make high-resolution gaming less viable, especially at higher quality presets.
