Counter-Strike: Global Offensive

Counter-Strike: Global Offensive with the AMD Ryzen 9 5900X and Intel Arc B570 presents a fascinating study in component scaling. The data reveals a configuration that is exceptionally fast, yet the relationship between resolution, CPU, and GPU tells a more nuanced story about where the bottlenecks lie in this particular esports title.

Resolution Scaling

The measured FPS data shows a dramatic and predictable decline as resolution increases, but the rate of that decline is the key indicator of system balance. At 1080p High settings, the combo produces an average of 343 FPS. Moving to 1440p High drops that to 236 FPS, a reduction of 107 FPS or roughly 31%. Stepping up to 4K High further reduces the average to 139 FPS, another substantial 97 FPS drop (41%) from the 1440p figure. This steep scaling curve from 1080p to 4K strongly suggests that the Intel Arc B570 becomes the limiting factor at higher resolutions, as the rendering load on the GPU increases exponentially with pixel count.

The data implies that at 1080p, the system is likely more CPU-bound, given the Ryzen 9 5900X's exceptional single-thread performance (evidenced by its 941 score in 3dmark_single_thread). However, the GPU's workload at 4K is so heavy that the frame rate collapses to nearly a third of the 1080p figure. The difference between Low and Ultra settings at 4K is also telling: 189 FPS at Low versus 119 FPS at Ultra, a 70 FPS spread that demonstrates the GPU's sensitivity to graphical fidelity. This is not a system that can brute-force 4K Ultra; it is a combination that excels at high-refresh-rate 1080p or 1440p gaming.

How This Combo Ranks

The combo ranks 2271 out of 2848 tested combinations in Counter-Strike: Global Offensive. This percentile placement—roughly in the 20th percentile of all tested combos—is surprisingly modest given the raw power of the components. The Ryzen 9 5900X itself sits in the 87th percentile among all CPUs, and the Arc B570 is in the 65th percentile among GPUs. Yet, when paired together for this specific game, the combination does not achieve a top-tier ranking.

This discrepancy suggests that CS:GO's engine may not be fully utilizing the 12-core/24-thread configuration of the 5900X, or that the game's optimization favors other hardware combinations. The data indicates that while this setup is undeniably fast in absolute terms, it does not compete with the top 20% of tested combos. This is a critical insight: a high-performing CPU and GPU individually do not guarantee a top-ranked pairing in every title. The rank of 2271 out of 2848 implies that many other combinations—likely with different CPU/GPU balances—deliver higher average frame rates in this specific game.

CPU Role

The AMD Ryzen 9 5900X is a 12-core, 24-thread processor based on the Zen 3 architecture, running on the AM4 socket. Its base clock is 3.70 GHz, boosting to 4.80 GHz, and it carries a substantial 64 MB of L3 cache. In synthetic benchmarks, it achieves a 3dmark_max_threads score of 10075 and a single-thread score of 941, with a Cinebench R23 multi-core score of 16262 and single-core score of 1527.

In the context of CS:GO, the game is historically known for being sensitive to single-thread performance. The 5900X's strong single-core showing (3469 in Passmark single-thread) should theoretically provide an excellent foundation. However, the combo rank suggests that the game may not be leveraging the full potential of the 24 threads. The data shows a significant gap between the 3dmark_2_threads score (1852) and the 3dmark_max_threads score (10075), indicating that the CPU scales well with more threads, but CS:GO likely does not require that level of parallel processing.

The 64 MB L3 cache is a notable asset for gaming, as it can hold larger portions of game data, reducing latency. Yet, the measured FPS at 1080p Low (465 FPS) versus 1080p Ultra (293 FPS) shows a 172 FPS drop, which is a substantial performance penalty driven by the GPU's rendering workload, not the CPU. The CPU appears capable of feeding frames well above 400 FPS at 1080p, but the GPU cannot keep up with higher settings. This suggests the CPU is not the primary bottleneck at higher resolutions, but its role at 1080p Low is to provide the headroom that allows the GPU to reach its maximum output.

Measured FPS Breakdown

The measured FPS data offers a complete picture across three resolutions and four quality presets. At 1920x1080, the results are exceptionally high across the board. Low settings yield an average of 465 FPS, which drops to 396 FPS at Medium, 343 FPS at High, and 293 FPS at Ultra. The Medium preset provides a minimum FPS of 337 and a maximum of 456, showing a stable frame delivery despite the high average.

Moving to 2560x1440, the averages remain competitive for high-refresh-rate monitors. Low settings produce 320 FPS, Medium delivers 273 FPS (with a 232 min and 314 max), High reaches 236 FPS, and Ultra drops to 201 FPS. The scaling from 1080p to 1440p shows an average reduction of roughly 30% across all settings, which is consistent with the increased pixel count.

At 3840x2160, the GPU workload becomes dominant. Low settings still manage an average of 189 FPS, but Medium falls to 161 FPS (with a 137 min and 185 max), High drops to 139 FPS, and Ultra bottoms out at 119 FPS. The 4K results clearly show the Arc B570's limitations at higher resolutions, as the frame rates dip below the 144Hz threshold that many competitive players target. The data indicates that this combination is best suited for 1080p or 1440p gaming, where it can maintain frame rates well above 200 FPS even at High settings.

GPU Role

The Intel Arc B570 is built on the Xe2-HPG architecture and features 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s of bandwidth. It has a base and boost clock of 2500 MHz, with 2304 shading units, 144 TMUs, and 80 ROPs. Its compute power is rated at 11.52 TFLOPS for FP32 operations. The GPU's passmark_g3d score is 14195, placing it in the 65th percentile of all GPUs.

The GPU's role becomes increasingly critical as resolution and settings increase. At 1080p Low, the GPU can produce 465 FPS, but this drops to 293 FPS at Ultra—a 37% reduction. This is a clear sign that the GPU's shading units and memory bandwidth are heavily taxed by the higher graphical settings. At 4K Ultra, the 119 FPS average is a stark contrast to the 1080p Low figure, showing a 74% performance reduction.

The 10 GB VRAM is sufficient for CS:GO at any resolution, as the game is not VRAM-intensive. However, the memory bandwidth of 380.0 GB/s appears to be a limiting factor at 4K, where the pixel fill rate (200.0 GPixel/s) and texture rate (360.0 GTexel/s) are pushed to their limits. The GPU's performance relative to its nearest rivals—the NVIDIA GeForce RTX 3070 Mobile (0.1% faster) and Intel Arc A750 (0.1% slower)—suggests that the B570 is a solid mid-range performer, but it does not have the headroom to dominate at 4K in this title.

Settings Recommendations

Based on the measured FPS data, the optimal experience depends on the user's display and priority. For competitive play on a 144Hz monitor, the 2560x1440 High preset is the sweet spot, delivering an average of 236 FPS with a strong visual upgrade over Low settings. This ensures the frame rate stays well above the refresh rate, minimizing screen tearing and input lag.

For users with a 240Hz monitor at 1080p, the Medium preset (396 FPS average) offers a good compromise, as it provides a significant visual improvement over Low (465 FPS) while still maintaining a massive frame rate cushion. The Ultra preset at 1080p drops to 293 FPS, which is still above 240Hz but leaves less headroom for demanding scenes.

At 4K, the data suggests that High settings (139 FPS) are the most viable option for a smooth experience on a 120Hz display, but users should be cautious about Ultra (119 FPS), which may cause noticeable dips below that threshold. The Low preset at 4K (189 FPS) is the safest choice for high-refresh-rate 4K gaming, but it sacrifices visual fidelity. The Medium preset at any resolution offers a balanced middle ground, with the 1440p Medium (273 FPS) being particularly well-suited for high-refresh-rate gaming. Ultimately, the data indicates this system is best leveraged at 1080p or 1440p, where it can deliver exceptional frame rates without compromising on graphical quality.
