GPU Role

The Intel Arc B390 is the decisive factor in this system's gaming performance. Its benchmark data shows a GPU that is fundamentally limited. With a 3DMark Steel Nomad score of 1482, it sits in the 9th percentile of all GPUs, placing it in the company of entries like the NVIDIA GeForce GT 520MX, which is only 1.3% slower. The B390's specifications align with this low standing. It features 1536 shading units, 48 TMUs, and 24 ROPs, with a boost clock of 2500 MHz. This hardware configuration yields a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s.

Crucially, the B390 operates as an integrated graphics processor (IGP) with system-shared memory. Its memory bandwidth is listed as "System Dependent," meaning its performance is tied to the speed of the system's DDR4 RAM, which is a far cry from dedicated video memory. This is a fundamental architectural constraint. The GPU's FP32 performance is rated at 7.680 TFLOPS, but in practice, for a game like Counter-Strike: Global Offensive, the combination of low raw compute relative to modern discrete GPUs and shared memory bandwidth creates a hard ceiling on frame rates.

The measured FPS data corroborates this. Even at the lowest settings and resolution tested (1920x1080 Low), the average frame rate is 303 FPS. While this is high, it is not exceptionally so for a game known for its scalability on high-end CPUs. The fact that the GPU is in the 9th percentile while still achieving these numbers suggests the game's engine is efficient, but the B390 is working near its maximum capacity. The GPU's role here is not to showcase high-refresh-rate potential but to provide a baseline level of playability. In every measured scenario, the B390's performance ceiling is reached before the CPU's considerable power can be fully utilized.

Resolution Scaling

The frame rate scaling from 1080p to 4K provides a clear picture of the system's bottleneck. When the resolution increases, the workload on the GPU increases significantly, while the CPU workload remains relatively constant. The data shows a dramatic drop in performance as resolution scales up, confirming that the Intel Arc B390 is the limiting component.

At 1080p High, the system averages 223 FPS. Moving to 1440p High, the average drops to 154 FPS, a 31% decrease. At 4K High, the average plummets to 91 FPS, a further 41% drop from the 1440p figure. This steep decline is a classic sign of a GPU-bound system. The CPU, the AMD Ryzen 7 5800XT, has ample headroom, but it cannot compensate for the GPU's inability to process the increasing number of pixels.

This pattern is consistent across all settings. For instance, on the Low preset, the system goes from 303 FPS at 1080p to 208 FPS at 1440p and finally to 123 FPS at 4K. The drop is less severe in percentage terms on Low settings because the GPU is less stressed by effects, but the trend is identical. The limiting component is always the GPU. If the CPU were the bottleneck, we would expect to see similar frame rates at 1080p and 1440p, as the CPU's workload would not change much. Instead, the significant FPS loss at higher resolutions points directly at the Intel Arc B390's limited fill rate and memory bandwidth. The system is unable to maintain high frame rates at 4K, with the Ultra preset dropping to an average of just 77 FPS.

Measured FPS Breakdown

The measured FPS data provides a complete picture of the system's performance across the tested matrix of resolutions and settings. The data reveals a consistent hierarchy: lower resolutions and settings yield higher frame rates, but the GPU's limitations are always present.

1920x1080: This is the system's most comfortable resolution. At Low settings, the average FPS is 303. Medium settings see a drop to 258 FPS, with a minimum of 219 and a maximum of 296 FPS. High settings average 223 FPS. The Ultra preset brings the average down to 190 FPS. All of these results are playable and benefit from high refresh rate monitors, but the scaling from Low to Ultra represents a significant performance hit.

2560x1440: At 1440p, the system starts to show strain. The Low preset averages 208 FPS. Medium settings average 177 FPS, with a minimum of 151 and a maximum of 204 FPS. The High preset drops to 154 FPS. The Ultra preset falls to an average of 131 FPS. While still playable, the frame rates are no longer in the range of top-tier competitive hardware.

3840x2160: At 4K resolution, the Intel Arc B390 becomes the clear limiting factor. Low settings average 123 FPS. Medium settings average 105 FPS, with a minimum of 89 and a maximum of 120 FPS. High settings drop to 91 FPS. The Ultra preset is the most demanding scenario tested, yielding an average of just 77 FPS. This is the only resolution where the Ultra preset dips below the 100 FPS mark, making it less ideal for smooth competitive play.

The frame time consistency, where provided, shows that the Medium preset has a tighter range. For example, at 1080p Medium, the FPS ranges from 219 to 296, while the average is 258. This suggests a more stable experience than what might be implied by the average alone. Overall, the data shows a system that is capable of high frame rates at 1080p but degrades predictably and significantly as resolution increases.

CPU Role

The AMD Ryzen 7 5800XT is a high-end desktop processor, and its benchmark results confirm its standing. It is an 8-core, 16-thread CPU based on the Zen 3 architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. Its Cinebench R23 multicore score is 23,794, and its single-core score is 3,359. It sits in the 81st percentile of all CPUs, with an average benchmark score of 29,879. Its nearest rivals include the AMD Ryzen 7 7840H and the AMD Ryzen 5 9600X, showing it is competitive with modern processors.

Despite this processing power, the CPU's role in this specific configuration is to be underutilized. In Counter-Strike: Global Offensive, the game's engine is known for being CPU-intensive, especially at high frame rates. However, the measured data shows that the system is GPU-bound in all scenarios. The CPU's immense power, indicated by its high single-thread score of 3,359, is unable to push frame rates higher because the GPU cannot render frames fast enough to keep up.

The 3DMark scores for the CPU further illustrate this point. The single-thread score is 959, while the 16-thread score is 7683. These scores indicate a powerful processor capable of handling the game's simulation and input logic with ease. The CPU is not the bottleneck; it is waiting on the GPU. The data suggests that for this game, the Ryzen 7 5800XT's performance is essentially irrelevant to the final FPS numbers. The bottleneck is so severe that the CPU's processing headroom is never fully taxed, making its high core count and clock speeds a non-factor in the final measured output. The system's performance is dictated entirely by the Intel Arc B390.

Settings Recommendations

Based on the measured FPS data, the optimal way to play Counter-Strike: Global Offensive on this system depends heavily on the user's resolution and performance priorities. The data shows a clear trade-off between visual fidelity and raw frame rate, with the GPU being the sole arbiter of performance.

For players using a 1920x1080 monitor, the Medium preset offers the best balance. It delivers an average of 258 FPS, which is 35 FPS lower than Low but provides a significantly better visual experience than the Low preset. The measured minimum of 219 FPS ensures that frame drops remain above the 200 FPS threshold, which is crucial for maintaining smooth gameplay on high refresh rate displays. The High preset is also viable at 223 FPS average, but the Medium preset's tighter frame time consistency (219-296 FPS range) suggests a more stable experience.

At 2560x1440, the Medium preset is again the recommended choice. It averages 177 FPS with a minimum of 151 FPS, which keeps the experience above the 144 Hz refresh rate mark for most of the time. The Low preset offers a higher average of 208 FPS, which is excellent for competitive play, but the Medium preset provides a substantial visual upgrade for a relatively small performance cost. The High and Ultra presets, with averages of 154 and 131 FPS, respectively, are less ideal for maintaining high refresh rates.

For 3840x2160, the Low preset is the only viable option for competitive play. It averages 123 FPS, which is above the 60 FPS minimum for smooth gameplay but below the 144 Hz threshold. The Medium preset averages 105 FPS, which is still playable but offers diminishing returns. The High and Ultra presets, with averages of 91 and 77 FPS, respectively, are best avoided for a fast-paced game like CS:GO, as the lower frame rates can negatively impact aiming and reaction times. In this scenario, the user must decide between the highest possible frame rate (Low) or a more visually polished but slower experience (Medium). The data strongly suggests that for this GPU, prioritizing frame rate over visual settings is the correct approach, especially at higher resolutions.
