Counter-Strike: Global Offensive

Counter-Strike: Global Offensive, a 2012 FPS, remains remarkably scalable on modern hardware. With the Intel Core i5-9400 paired with the Intel Arc B580, the measured data reveals a configuration that prioritizes raw frame rate, even at higher resolutions. The performance profile is consistent across the board, indicating a well-balanced pairing where the GPU and CPU both contribute significantly to the final output.

Resolution Scaling

The FPS data shows a classic pattern of diminishing returns as resolution increases. At 1080p, the system is clearly CPU-bound, delivering an average of 525.1 FPS on Low settings. This figure drops to 360.9 FPS at 1440p and further to 214.3 FPS at 4K, representing a 31% and 59% decrease from the 1080p baseline, respectively. This steep decline at 4K suggests the workload is shifting heavily onto the GPU, which is still capable of producing very high frame rates.

The scaling from 1080p to 1440p at High settings is less severe, with the average FPS dropping from 385.2 to 267, a 31% reduction. The jump from 1440p to 4K is more pronounced, as the 4K High average of 155.7 FPS is 42% lower than the 1440p result. This indicates that the Intel Arc B580, while powerful, faces a significantly heavier pixel-pushing workload at 4K. The data supports a conclusion that 1080p and 1440p are the sweet spots for this combination, where the CPU can feed the GPU effectively and maintain frame rates far beyond the refresh rate of most monitors.

The relative performance gap between resolutions narrows as settings increase. For instance, at 1080p, the gap between Low and Ultra is 195.1 FPS. At 4K, this gap shrinks to 82.9 FPS. This convergence suggests that at 4K, the GPU becomes the limiting factor, making the choice of settings less impactful on FPS than at lower resolutions where CPU overhead is more dominant.

GPU Role

The Intel Arc B580's specifications are central to understanding its performance. With 12 GB of GDDR6 memory on a 192-bit bus, it provides a 456.0 GB/s memory bandwidth. This is ample for a competitive title like CS:GO, which is not known for requiring large amounts of VRAM. The generous memory allocation ensures that even at 4K with Ultra settings, the card is unlikely to be bottlenecked by memory capacity, allowing the 20 RT cores and 2560 shading units to operate without data starvation.

The GPU's clock behavior is unique, as its base and boost clocks are both listed at 2670 MHz. This constant clock speed suggests a stable performance envelope. The card's 13.67 TFLOPS of FP32 compute is a key metric for this game, which relies heavily on raw shader throughput. The benchmark results confirm this, with a Passmark G3D score of 15748, placing it in the 66th percentile of all GPUs and just 0.7% behind the NVIDIA GeForce RTX 4060 in average benchmark score. This data indicates the B580 is a potent performer for this title.

The transition from Low to Ultra settings at 4K shows a clear GPU workload scaling. Average FPS falls from 214.3 on Low to 131.4 on Ultra. This 82.9 FPS drop is the largest across all resolutions, reinforcing that the GPU is the primary component under stress at 4K. The 8-pin power connector and 190 W TDP are consistent with a card of this performance class, supporting the notion that it is fully capable of sustaining these high frame rates.

Settings Recommendations

For players with a 1080p or 1440p monitor, the data strongly suggests that High settings are the optimal choice for a competitive experience. At 1080p, High yields an average of 385.2 FPS, while at 1440p it achieves 267 FPS. Both figures are high enough to fully utilize a 240 Hz or even a 360 Hz display, providing a smooth and responsive experience without sacrificing visual clarity. The jump to Ultra settings at these resolutions reduces performance by 14% and 16%, respectively, which may not be justifiable for the minor visual improvements in a fast-paced tactical shooter.

At 4K, the recommendation shifts to Medium settings. The Medium preset delivers 182.6 FPS, which is a 39% improvement over the Ultra preset's 131.4 FPS. This frame rate is high enough for a 144 Hz display, making it the best balance between visual fidelity and performance for 4K users. The Low preset at 4K does offer a higher 214.3 FPS, but the visual compromise is severe and the performance gain over Medium is only 17%, making Medium the more sensible choice for most players.

The Ultra preset is only recommended for 1080p, where the system can still maintain an average of 330 FPS. This setting allows for maximum visual quality with a frame rate that is still exceptionally high. However, for players who prioritize maximum FPS for competitive play, the Low preset at 1080p, with its 525.1 FPS average, is the definitive choice, as it minimizes input latency and provides the greatest headroom for frame time consistency.

Measured FPS Breakdown

The complete dataset of average FPS is as follows.

At 1920x1080:

• Low: 525.1 FPS
• Medium: 445.1 FPS
• High: 385.2 FPS
• Ultra: 330.0 FPS

At 2560x1440:

• Low: 360.9 FPS
• Medium: 305.1 FPS
• High: 267.0 FPS
• Ultra: 224.0 FPS

At 3840x2160:

• Low: 214.3 FPS
• Medium: 182.6 FPS
• High: 155.7 FPS
• Ultra: 131.4 FPS

The data shows a consistent hierarchy across all resolutions: Low is fastest, followed by Medium, High, and Ultra. The performance delta between each setting is also consistent, with a roughly 15-20% drop for each step up in quality. This predictable scaling is a sign of a well-optimized engine and a stable driver. The results at 4K Ultra, while the lowest of the set, still exceed 130 FPS, demonstrating that this combination is not just for esports-level 1080p play but is also a capable 4K machine.
