GPU Role

The Intel Arc B390's role in this system is defined by its integrated nature. As an IGP with "System Shared" memory, its performance is inherently tied to the rest of the system's components. The GPU's memory bandwidth is listed as "System Dependent," highlighting that its access to data is not a fixed specification but rather a function of the host system's memory controller and RAM. This is a critical factor in how the measured FPS scales across different resolutions.

The Arc B390 is based on the Xe3-LPG architecture and operates with a base clock of 300 MHz and a boost clock of 2500 MHz. It has 1536 shading units, 48 TMUs, and 24 ROPs. Its raw compute capabilities are modest, with an FP32 throughput of 7.680 TFLOPS. The GPU holds a 9th percentile ranking among all GPUs, which contextualizes its performance as being in the lowest tier of the current market. Its nearest rivals, according to benchmark data, are the NVIDIA GeForce GT 520MX and GeForce 800M, from which it leads by a margin of just over 1%. This positioning suggests that while it can render the game, it does so with the performance headroom of an entry-level discrete GPU from over a decade ago.

The measured FPS in Counter-Strike: Global Offensive demonstrates that the GPU is the primary constraint. At 1920x1080 with Low settings, the system produces an average of 303 FPS. This high frame rate suggests that the CPU is capable of feeding the GPU with enough data for it to achieve its maximum output. However, the GPU's limitations become apparent when settings are increased. The drop from Low to Ultra at 1080p is a 113 FPS reduction, showing the GPU's fill-rate and shading capabilities are quickly overwhelmed by higher graphical demands. The GPU is consistently the bottleneck, preventing the system from scaling to even higher frame rates that the CPU could likely support.

Resolution Scaling

The FPS scaling from 1080p to 4K clearly illustrates the shift in workload from the CPU to the GPU. At 1080p with High settings, the system averages 223 FPS. When the resolution is increased to 2560x1440, the average FPS drops to 154. This is a significant 31% decrease, indicating that the GPU is already becoming saturated as it is asked to render more pixels. Moving to 3840x2160, the average FPS falls further to 91, a 41% drop from the 1440p figure and a 59% drop from the 1080p result.

This pattern is consistent across all settings. At Low settings, the system goes from 303 FPS at 1080p, to 208 FPS at 1440p, and finally to 123 FPS at 4K. The scaling is more dramatic at lower settings because the GPU is less burdened by shading work, so the increase in pixel count becomes the dominant factor. At Medium settings, the averages are 258 FPS, 177 FPS, and 105 FPS for 1080p, 1440p, and 4K, respectively. The Ultra preset shows the same trend, with the system averaging 190 FPS at 1080p, 131 FPS at 1440p, and 77 FPS at 4K.

The fact that FPS drops by roughly 40-50% each time the resolution nearly doubles in pixel count indicates that the system is heavily GPU-limited. If the CPU were the bottleneck, the frame rates at 1080p and 1440p would be much closer, as the CPU's workload would not scale as much with resolution. The data strongly suggests that the Intel Arc B390 is the limiting component, and its performance is directly tied to the number of pixels it must fill. The Ryzen 5 5600X, being a 75th percentile CPU, has ample headroom to handle the game's logic and draw calls, but its power is left untapped as the GPU struggles to keep up with the rendering demands.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across all settings and resolutions.

At 1920x1080, the system delivers its highest performance. With Low settings, it achieves an average of 303 FPS. Moving to Medium settings, the average drops to 258 FPS, with a minimum of 219 FPS and a maximum of 296 FPS. The High preset averages 223 FPS. At Ultra settings, the average is 190 FPS. This shows that even at the highest quality preset, the system can drive a high-refresh-rate 1080p monitor effectively, though the gap between Low and Ultra is substantial.

At 2560x1440, the performance scales down accordingly. The Low preset averages 208 FPS. The Medium preset averages 177 FPS, with figures ranging from 151 FPS to 204 FPS. The High preset yields an average of 154 FPS. The Ultra preset brings the average down to 131 FPS. These numbers indicate that 1440p is still very playable, but the system is more comfortable at the lower settings presets if a consistently high frame rate is desired.

At 3840x2160, the integrated GPU is pushed to its limits. The Low preset is the only setting that provides a frame rate above 120 FPS, averaging 123 FPS. The Medium preset averages 105 FPS, with a minimum of 89 FPS and a maximum of 120 FPS. The High preset drops to an average of 91 FPS. Finally, the Ultra preset averages 77 FPS. While these are still playable frame rates, the system is clearly not optimized for 4K gaming, and any demanding scene could push the frame rate below the smooth 60 FPS threshold.

The data shows a consistent and predictable scaling pattern. Each increase in resolution or settings level reduces the average FPS, with the impact being most pronounced at 4K resolution. The Medium preset is the only one with recorded min/max FPS data, showing a 31 FPS variance at 1080p, a 53 FPS variance at 1440p, and a 31 FPS variance at 4K.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and refresh rate of the user's display.

For users with a 1920x1080 monitor, the Ultra preset is the recommended choice. With an average of 190 FPS, it provides a smooth and visually superior experience without sacrificing performance. The game remains highly responsive, and the system has enough headroom to handle intense action sequences without dropping below playable levels. The High preset, at 223 FPS, is also excellent, but the visual upgrade from High to Ultra is worth the 33 FPS trade-off for most players, given the high baseline.

For users with a 2560x1440 monitor, the High preset offers the best balance. Averaging 154 FPS, it is a significant improvement over the Ultra preset's 131 FPS, while still providing a high level of visual fidelity. The Medium preset, at 177 FPS, is a viable alternative for those who prioritize maximum frame rates, but the jump in quality from Medium to High is substantial. The data suggests that the system can handle High settings comfortably at this resolution.

For users with a 3840x2160 monitor, the Low preset is the only option that guarantees a consistently high frame rate. Averaging 123 FPS, it is the only preset that stays comfortably above the 100 FPS mark. The Medium preset, at 105 FPS, is acceptable, but its minimum FPS of 89 shows that it can dip closer to the 60 FPS threshold. The High and Ultra presets, with averages of 91 FPS and 77 FPS respectively, are not recommended for competitive play, as they sacrifice too much frame rate for visual fidelity on a system with this GPU.

In summary, the High preset is the sweet spot for 1080p and 1440p gaming, while Low is the only sensible choice for 4K. The data indicates that the GPU is the limiting factor at higher resolutions, so reducing the graphical load is the only way to maintain a high frame rate.

CPU Role

The AMD Ryzen 5 5600X is a powerful desktop processor that is more than capable of handling the demands of Counter-Strike: Global Offensive. It features 6 cores and 12 threads based on the Zen 3 architecture. Its base clock of 3.70 GHz and boost clock of 4.60 GHz provide strong single-threaded performance, which is critical for a game like CS:GO that is heavily reliant on CPU performance for game logic and draw calls.

The CPU's benchmark scores confirm its strength. It achieves a single-thread score of 1541 in Cinebench R23 and a multi-core score of 11838. Its average benchmark score of 21771 places it in the 75th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 7 4800H and Intel Core i7-11700, with the 5600X performing within 0.5% of both. This indicates that the 5600X offers performance on par with those well-regarded mid-range and high-end parts.

In this specific system, the CPU's role is to feed the Intel Arc B390 with frames. The measured FPS data shows that the CPU is not the bottleneck. At 1080p Low settings, the system achieves 303 FPS. If the CPU were the limiting factor, this number would be much lower, as the GPU would be waiting for the CPU to finish its calculations. Instead, the fact that the FPS drops so dramatically when resolution increases from 1080p to 4K (e.g., from 303 to 123 FPS on Low settings) proves that the GPU is saturated and is the primary constraint.

The CPU has more than enough headroom to handle the game's physics, AI, and networking tasks. Its 32 MB of L3 cache and 12 threads ensure that it can manage all background processes without interfering with the game's main thread. While the GPU's performance holds the system back in terms of raw FPS, the Ryzen 5 5600X ensures that frame times will be consistent and that the system will not stutter due to CPU limitations. In this configuration, the CPU is a high-performance component whose capabilities are largely untapped, leaving significant potential for a future GPU upgrade.
