Counter-Strike: Global Offensive

Counter-Strike: Global Offensive, a title from 2012 built on the Source engine, often behaves differently than modern shooters for hardware scaling. The measured data for the AMD Ryzen 5 2600 paired with the Intel Arc B390 reveals a configuration that is heavily influenced by the graphics solution, particularly as resolution increases. This analysis examines the measured FPS across three resolutions and four quality presets to determine where the bottleneck lies and what the performance envelope truly is for this specific combination.

Resolution Scaling

The measured FPS data shows a clear and predictable pattern as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average frame rate drops from 223 FPS at 1080p to 154 FPS at 1440p, and finally to 91 FPS at 4K. This represents a significant 59% reduction in performance from 1080p to 4K. The Low preset follows a similar trajectory, starting at 303 FPS at 1080p, dropping to 208 FPS at 1440p, and settling at 123 FPS at 4K. The frame rate decline is not linear, indicating that the performance ceiling is being approached at lower resolutions.

The scaling pattern suggests that at 1080p, the system is likely hitting a limit that is not purely GPU-bound, as the difference between 1080p and 1440p at Low settings is 95 FPS, while the difference between 1440p and 4K is 85 FPS. This relatively consistent drop per resolution step implies that the Intel Arc B390's rendering capabilities are the primary constraint. At 4K, the pixel count is four times that of 1080p, which would explain the substantial FPS reduction observed across all presets. The data indicates that this integrated GPU solution is not designed for high-refresh-rate 4K gaming in CS:GO, as even the Low preset cannot maintain a 144 FPS average.

The gap between the Low and Ultra presets also widens with resolution. At 1080p, the difference between Low and Ultra is 113 FPS (303 vs 190). At 4K, this gap narrows to 46 FPS (123 vs 77). This convergence suggests that at higher resolutions, the GPU becomes fully saturated, and the impact of graphical settings diminishes relative to the raw pixel throughput required. The measured results indicate a system that is balanced for 1080p gaming but increasingly GPU-limited as resolution climbs, making 4K a challenging target for this hardware pairing.

CPU Role

The AMD Ryzen 5 2600 is a 6-core, 12-thread processor from the 2000 series, based on the Zen+ architecture. It features a base clock of 3.40 GHz and a boost clock of 3.90 GHz, with a 65W TDP. In the context of CS:GO, which is known to be sensitive to single-thread performance, this CPU's capabilities are a crucial factor. The benchmark data shows a Cinebench R15 single-core score of 157.3 and a multi-core score of 1248. The Geekbench scores are 1154 (single-core) and 5648 (multi-core), while PassMark single-thread performance is 2239.

These metrics position the Ryzen 5 2600 as a mid-range processor from its generation. Its percentile ranking against all CPUs is 75, meaning it outperforms a majority of processors in the database. However, its nearest rivals in average benchmark score include the Intel Core Ultra 5 228V (0.2% faster) and the Intel Core i9-11900H (0.5% faster), while the Intel Xeon D-1746TER is slightly slower at -0.7%. This indicates that while the CPU is not a top-tier performer, it holds its own against a wide range of competitors.

For CS:GO, the CPU's role is to feed the GPU with draw calls and process game logic. The measured FPS at 1080p Low (303 FPS) suggests that the CPU is capable of delivering high frame rates, but it may be approaching its limit. The fact that the FPS at 1080p Low is significantly higher than at 4K Low (123 FPS) implies that the GPU is the limiting factor at higher resolutions. However, the CPU's single-thread performance could be a constraint at lower resolutions where the GPU has more headroom. The data suggests that this processor is sufficient for high-FPS 1080p gameplay, but its older architecture may prevent it from reaching the extreme frame rates seen with newer, higher-clocked CPUs.

GPU Role

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, built on a 3nm process. It features 1536 shading units, 48 texture mapping units, and 24 ROPs, with a boost clock of 2500 MHz. The GPU's memory is "System Shared," meaning it relies on the system's DDR4 memory, and its bandwidth is described as "System Dependent." The measured 3DMark Steel Nomad DX12 score is 1482, which places it in the 9th percentile of all GPUs, indicating relatively low performance compared to discrete solutions.

The GPU's nearest rivals in benchmark scores are all older NVIDIA offerings: the GeForce GT 520MX (1.3% faster), GeForce 800M (1.5% faster), GeForce GT 625 OEM (2.5% faster), and GeForce GT 710 (2.7% faster). This comparison starkly highlights the Arc B390's performance class, which is far below modern discrete graphics cards. The FP32 performance is rated at 7.680 TFLOPS, and the pixel rate is 60.00 GPixel/s, but these figures are rendered moot by the system-shared memory architecture.

In CS:GO, the GPU's role is to render the scene and handle effects. The measured FPS data shows that the Arc B390 struggles at 4K, with the High preset yielding only 91 FPS. At 1080p, however, it can deliver playable frame rates, with the High preset at 223 FPS and Low at 303 FPS. The GPU's low percentile ranking and modest compute capabilities suggest that it is the primary bottleneck in this pairing, especially at higher resolutions. The fact that the GPU's memory bandwidth is system-dependent means that performance can vary based on the CPU's memory configuration, but in this case, the Ryzen 5 2600's dual-channel DDR4 support provides a baseline that the Arc B390 must work with.

How This Combo Ranks

The combination of the AMD Ryzen 5 2600 and Intel Arc B390 ranks 2510th out of 2848 tested combinations for Counter-Strike: Global Offensive. This places it in the bottom 12% of all tested systems, reflecting the GPU's weak performance relative to other graphics solutions. The rank of 2510 indicates that a substantial majority of CPU-GPU pairings in the database achieve higher frame rates in this game.

This low ranking is primarily attributable to the Intel Arc B390, which sits in the 9th percentile of all GPUs. The CPU, by contrast, performs better relative to its peers, ranking in the 75th percentile. The disparity between the CPU's and GPU's percentile rankings suggests that this pairing is heavily unbalanced, with the GPU acting as a severe bottleneck. While the CPU can deliver adequate single-thread performance for CS:GO, the GPU's integrated nature and shared memory architecture prevent it from translating that CPU capability into high frame rates.

For context, the GPU's nearest rivals are all legacy NVIDIA parts from over a decade ago. The fact that the Arc B390 is only 1.3% faster than a GeForce GT 520MX, which was a low-end mobile GPU in its era, underscores the performance category this system falls into. Consequently, this combo ranks where it does because the GPU cannot compete with even entry-level discrete graphics cards, making it a poor choice for CS:GO players seeking competitive frame rates.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and desired frame rate. At 1920x1080, the Low preset delivers 303 FPS, which is well above the 144 Hz refresh rate common in competitive monitors. The High preset at 1080p still offers 223 FPS, providing a good balance between visual quality and performance. The Medium preset at 1080p yields 258 FPS, and even Ultra maintains 190 FPS, making 1080p the only resolution where all presets are viable for high-refresh-rate gaming.

At 2560x1440, the Low preset drops to 208 FPS, which is still suitable for 144 Hz displays, but the High preset falls to 154 FPS. For players prioritizing frame rate, Low is the recommended choice at 1440p. The Medium preset at 177 FPS is also acceptable, but Ultra at 131 FPS may not be sufficient for competitive play. At 3840x2160, the situation becomes more constrained. The Low preset at 123 FPS is the only setting that approaches 120 FPS, while High (91 FPS), Medium (105 FPS), and Ultra (77 FPS) all fall below 100 FPS, making them less ideal for smooth gameplay.

The data suggests that for the best experience, players should target 1080p with High or Medium settings, as these provide high frame rates with improved visuals over Low. At 1440p, Low or Medium are the safest choices to maintain high FPS. At 4K, Low is the only setting that offers a playable experience near 120 FPS, but even then, the frame rate is borderline. Ultimately, the recommendation is to prioritize lower resolutions and presets to maximize frame rate, given the GPU's limitations.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across resolutions and settings. At 1920x1080, the Low preset achieves an average of 303 FPS, which is the highest recorded for this combo. The Medium preset at 1080p averages 258 FPS, with a minimum of 219 FPS and a maximum of 296 FPS. High settings at 1080p yield 223 FPS, while Ultra delivers 190 FPS. This shows a clear performance hierarchy, with Low being the fastest and Ultra being the slowest.

Moving to 2560x1440, the Low preset averages 208 FPS. Medium settings at 1440p produce 177 FPS, with a min-max range of 151 to 204 FPS. High settings drop to 154 FPS, and Ultra falls to 131 FPS. The performance drop from 1080p to 1440p is substantial, with the Low preset losing 95 FPS. At 3840x2160, the Low preset averages 123 FPS, which is the only 4K setting above 100 FPS. Medium settings at 4K average 105 FPS, with a range of 89 to 120 FPS. High settings average 91 FPS, and Ultra averages 77 FPS.

The data reveals a consistent pattern: each resolution step up reduces FPS by a significant margin, and each settings increase also reduces FPS. The Medium preset at each resolution shows the most detailed min-max data, with the 1080p range being 219-296 FPS, the 1440p range being 151-204 FPS, and the 4K range being 89-120 FPS. This granularity indicates that frame pacing can vary, but the averages provide a reliable baseline. Overall, the measured FPS breakdown shows that this combo is best suited for 1080p gaming, with diminishing returns at higher resolutions.
