Counter-Strike: Global Offensive

Counter-Strike: Global Offensive with the AMD Ryzen 7 5800X and Intel Arc B370 presents a clear performance hierarchy across resolutions. The measured data shows that this combination is strongly CPU-bound at lower resolutions, with the GPU becoming the limiting factor only as resolution climbs to 4K. At 1080p, the average frame rates are exceptionally high, reaching 273 FPS on Low settings, which indicates the CPU is doing the heavy lifting. The Intel Arc B370, with its modest specifications and low percentile ranking, is the bottleneck at 4K, where the frame rates drop to a range that is still playable but far from the high refresh rate territory seen at 1080p. This pairing is not balanced for 4K gaming, but it provides a competitive esports experience at 1080p and 1440p.

Resolution Scaling

The frame rate data reveals a steep performance drop as resolution increases, which is a classic sign of a GPU-limited scenario at higher pixel counts. At 1080p with Low settings, the system produces 273 FPS. Moving to 2560x1440 at the same settings, the average falls to 188 FPS, a reduction of 85 FPS. At 4K with Low settings, the average is 111 FPS, which is 162 FPS lower than the 1080p result. This scaling pattern shows that the GPU’s rendering load is the primary factor limiting performance as resolution increases. The CPU, with its 8 cores and 16 threads, has ample headroom at these settings, so the frame rate drop is almost entirely attributable to the Intel Arc B370’s pixel throughput.

The scaling from 1080p to 1440p at High settings shows a similar trend. The average FPS drops from 202 to 139, a 63 FPS decrease. From 1440p to 4K at High settings, the average falls from 139 to 82, a 57 FPS decrease. This consistent drop of roughly 30% at each step indicates that the GPU is being saturated progressively. The data suggests that the Intel Arc B370, with its 20 ROPs and 48.00 GPixel/s pixel rate, cannot sustain high frame rates at 4K, even in a game as old and well-optimized as Counter-Strike: Global Offensive. The 4K results, ranging from 70 FPS on Ultra to 111 FPS on Low, are the only metrics where the GPU’s limitation is the dominant factor.

The pattern is consistent with a system where the CPU can deliver far more frames than the GPU can render at high resolutions. At 1080p, the CPU’s strong single-thread performance, evidenced by a 3dmark_single_thread score of 943, is sufficient to push frame rates to the 200-273 FPS range. At 4K, however, the GPU’s 6.144 TFLOPS of FP32 performance and shared system memory become the bottleneck, capping average frame rates well below what the CPU could theoretically support. The frame rate deltas between 1080p and 4K are 101 FPS for High, 162 FPS for Low, and 138 FPS for Medium settings, which underscores the GPU’s inability to scale with resolution.

Settings Recommendations

For this combination, the optimal settings depend on the target resolution and refresh rate. At 1080p, the Low preset delivers the highest average frame rate at 273 FPS, which is ideal for competitive play on a 240Hz or higher monitor. The Medium preset, with an average of 233 FPS, offers a substantial improvement in visual quality while still maintaining frame rates above 200 FPS, making it a strong choice for players seeking a balance between responsiveness and image fidelity. The High preset at 202 FPS is also viable, but the jump from Medium to High only yields a 13% performance cost, which might not be justified for the visual gains in a fast-paced shooter where clarity of motion is paramount. The Ultra preset at 172 FPS is the least competitive option at this resolution, as the extra visual detail is unlikely to be perceptible in the heat of a match.

At 2560x1440, the Low preset’s 188 FPS average remains high enough for high refresh rate monitors, though the Medium preset at 160 FPS is a more balanced option. The High preset at 139 FPS is still playable and provides a good visual upgrade, but the Ultra preset at 118 FPS is the first point where frame rates dip below the 120 FPS threshold that many competitive players consider the minimum for smooth gameplay. The data suggests that Medium is the sweet spot at 1440p, offering 160 FPS average with a recorded minimum of 136 FPS, which ensures that even in demanding scenes, the frame rate stays above the refresh rate of most 144Hz monitors.

At 4K, no settings preset provides a truly competitive frame rate. The Low preset’s 111 FPS average is the only option that breaks the 100 FPS barrier, while Medium averages 95 FPS with a minimum of 80 FPS, and High averages 82 FPS. The Ultra preset at 70 FPS is the least desirable, as it borders on the low end of playability for a first-person shooter. For this resolution, the data indicates that Low settings are the only viable choice, and even then, players would need to accept a significant compromise in visual fidelity to achieve a playable frame rate. The combination of the CPU and GPU is not suited for 4K gaming in this title.

GPU Role

The Intel Arc B370 is the clear performance limiter in this pairing, particularly at higher resolutions. Its benchmark results are modest, with a 3dmark_steel_nomad_dx12 score of 1184, placing it in the 5th percentile of all GPUs. This low percentile ranking is reflected in the measured frame rates, which show the GPU struggling to maintain high FPS at 4K. The nearest rivals to the Arc B370, according to the data, are older cards like the ATI Mobility Radeon HD 5570 and the ATI Radeon HD 5770, with average scores of 1186 and 1190, respectively. The deltaPct values are -0.2% and -0.5%, meaning the Arc B370 is essentially on par with these older parts, which explains its limited performance headroom.

The GPU’s specifications further clarify its limitations. It has a base clock of 300 MHz and a boost clock of 2400 MHz, which allows for a significant clock speed increase under load. However, its memory configuration is "System Shared," meaning it relies on the CPU’s DDR4 memory rather than dedicated VRAM. This shared memory architecture can lead to bandwidth limitations, especially at higher resolutions where the demand for texture data increases. The memory bandwidth is listed as "System Dependent," which in this case with the Ryzen 7 5800X’s dual-channel DDR4 support, yields a theoretical 51.2 GB/s. This is a low bandwidth figure for a GPU, and it likely contributes to the frame rate drops seen at 4K.

The GPU’s pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are also modest figures. With only 20 ROPs and 40 TMUs, the Arc B370 is not designed for high-resolution gaming. The FP32 throughput of 6.144 TFLOPS is low by modern standards, further confirming its position as an entry-level part. The data shows that at 4K Ultra, the GPU can only manage an average of 70 FPS, which is a clear indication that it is overwhelmed by the pixel count. The fact that the GPU’s percentile rank is 5th places it in the bottom tier of all tested GPUs, which is consistent with the observed performance in this game.

How This Combo Ranks

The combination of the AMD Ryzen 7 5800X and Intel Arc B370 ranks 2615 out of 2848 tested combos for Counter-Strike: Global Offensive. This places it in the bottom 8% of all combinations, which is a poor showing for a system with a high-end CPU. The rank is driven almost entirely by the GPU’s weak performance, as the CPU itself is capable of far higher frame rates. The data indicates that this pairing is heavily imbalanced, with the GPU acting as a severe bottleneck. The combo rank of 2615 out of 2848 means that there are 233 other combinations that perform worse, but the vast majority of tested systems outperform this one.

The CPU’s individual performance is much stronger. The Ryzen 7 5800X has an average benchmark score of 29123, placing it in the 81st percentile of all CPUs. Its nearest rivals include the Intel Core Ultra 5 135H with a score of 29093 and a deltaPct of 0.1%, and the AMD Ryzen 5 5600XT with a score of 28940 and a deltaPct of 0.6%. This means the 5800X is slightly ahead of these parts, but the differences are within a 1% margin. The CPU’s strong performance is evident in the 1080p frame rates, which exceed 200 FPS on most settings, but the combo rank suffers because the GPU cannot keep up with the CPU’s output.

The disparity between the CPU’s 81st percentile ranking and the combo’s 8th percentile ranking highlights the extent of the GPU bottleneck. In a game like Counter-Strike: Global Offensive, which is known to be CPU-intensive, the 5800X’s 8 cores and 16 threads are more than sufficient to drive high frame rates. However, the Intel Arc B370’s 5th percentile GPU ranking means that any resolution above 1080p will result in a significant performance penalty. The data suggests that this combo is only competitive at 1080p, where the CPU can compensate for the GPU’s weaknesses. At 1440p and 4K, the combo’s ranking would be even lower, as the frame rates fall below the thresholds for competitive play.

CPU Role

The AMD Ryzen 7 5800X plays a crucial role in ensuring high frame rates at lower resolutions. With 8 cores and 16 threads based on the Zen 3 architecture, this CPU has the processing power to handle the game’s simulation and draw call logic without becoming a bottleneck. Its base clock of 3.80 GHz and boost clock of 4.70 GHz provide strong single-thread performance, which is critical for Counter-Strike: Global Offensive’s engine. The 3dmark_single_thread score of 943 and the passmark_single_thread score of 3445 both reflect the CPU’s ability to handle the game’s primary thread efficiently. The L3 cache of 32 MB also helps reduce memory latency, which is beneficial for maintaining consistent frame times.

The CPU’s performance is further evidenced by its Cinebench R23 multicore score of 15476 and single-core score of 1574.5. These scores indicate that the CPU can sustain high clock speeds across all cores, which is important for handling background tasks and game logic simultaneously. However, in this specific game, the CPU’s role is to feed the GPU with draw calls and physics calculations. At 1080p, the CPU is able to push frame rates to 273 FPS on Low settings, which demonstrates that it is not the limiting factor. The data shows that the CPU’s performance is more than adequate for this title, as the frame rate drops at higher resolutions are entirely attributable to the GPU.

The CPU’s memory support for DDR4 with a dual-channel bus and 51.2 GB/s bandwidth is adequate for the game’s needs, though it is not as fast as newer DDR5 platforms. The 20 PCIe Gen 4 lanes provide sufficient bandwidth for the GPU, though the Arc B370’s shared memory architecture means it accesses system memory rather than dedicated VRAM. The CPU’s 105W TDP and 7nm process node from TSMC ensure that it runs efficiently without excessive heat generation. In terms of its rivals, the Ryzen 7 5800X is 0.1% ahead of the Intel Core Ultra 5 135H and 0.6% ahead of the AMD Ryzen 5 5600XT in average benchmark scores, placing it at the top of its immediate peer group. This performance headroom is what allows the combo to achieve playable frame rates at 1080p, despite the GPU’s limitations.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates across settings are as follows: Low produces 273 FPS, Medium produces 233 FPS with a minimum of 198 and maximum of 268, High produces 202 FPS, and Ultra produces 172 FPS. The difference between Low and Ultra is 101 FPS, which represents a 37% performance drop for the highest visual quality. The Medium preset’s minimum of 198 FPS ensures that even in the most demanding scenes, the frame rate stays above 144Hz, making it the recommended preset for high refresh rate gaming. The High preset at 202 FPS is also excellent, but the Ultra preset’s 172 FPS average might cause noticeable dips on a 240Hz monitor.

At 2560x1440, the average frame rates are: Low at 188 FPS, Medium at 160 FPS with a minimum of 136 and maximum of 184, High at 139 FPS, and Ultra at 118 FPS. The step from Low to Medium costs 28 FPS, while the step from Medium to High costs 21 FPS, and from High to Ultra costs another 21 FPS. The Medium preset’s minimum of 136 FPS is just above the 120Hz threshold, making it a viable option for 144Hz monitors, though players may notice occasional dips. The High preset at 139 FPS is also playable, but the Ultra preset at 118 FPS is borderline for competitive play, as frame rates below 120 FPS can introduce input latency.

At 3840x2160, the average frame rates are: Low at 111 FPS, Medium at 95 FPS with a minimum of 80 and maximum of 109, High at 82 FPS, and Ultra at 70 FPS. The Low preset is the only one that maintains an average above 100 FPS, making it the sole viable option for 4K gaming. The Medium preset’s minimum of 80 FPS indicates that the frame rate can drop significantly during intense action, which is not ideal for a competitive shooter. The High and Ultra presets at 82 and 70 FPS respectively are below the threshold for smooth gameplay, and the data suggests that this combination should be avoided at 4K unless visual quality is prioritized over performance. The frame rate deltas between 1080p and 4K are substantial, with the Low preset losing 162 FPS, the Medium preset losing 138 FPS, the High preset losing 120 FPS, and the Ultra preset losing 102 FPS, further confirming the GPU’s role as the bottleneck.
