Counter-Strike: Global Offensive

The AMD Ryzen 5 7500X3D paired with the Intel Arc B370 in Counter-Strike: Global Offensive presents a highly unusual performance profile. The data shows a system that is dramatically CPU-limited at lower resolutions, while the integrated-class GPU becomes the dominant constraint as resolution increases. This combination ranks 2615th out of 2848 tracked combos in this game, placing it in the lower percentile of all systems, which is primarily a reflection of the GPU's limited capabilities relative to the processor.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a clear story about where the bottleneck lies in this system. At 1080p with Low settings, the system produces 273 FPS average. Moving to 1440p at the same settings drops that to 188 FPS, a reduction of 85 FPS or approximately 31%. Continuing to 4K at Low settings yields 111 FPS, another 77 FPS drop from 1440p, representing a further 41% decline. This steep and consistent drop as resolution increases indicates that the Intel Arc B370's rendering throughput is the limiting factor once pixel count rises.

The pattern is similar across all settings presets. At High settings, the system delivers 202 FPS at 1080p, 139 FPS at 1440p, and 82 FPS at 4K. The delta between 1080p and 4K at High settings is 120 FPS, which is a 59% reduction. At Ultra settings, the numbers are 172 FPS at 1080p, 118 FPS at 1440p, and 70 FPS at 4K, representing a 102 FPS or 59% drop from the lowest to highest resolution tested.

Interestingly, the scaling factor between 1080p and 1440p is relatively modest compared to the jump from 1440p to 4K. At Medium settings, for instance, 1080p delivers 233 FPS, 1440p delivers 160 FPS, and 4K delivers 95 FPS. The 1080p to 1440p drop is 73 FPS, while the 1440p to 4K drop is 65 FPS. This suggests that the CPU, with its 6 cores and 12 threads, is still capable of feeding the GPU adequately at 1440p, but at 4K the GPU's pixel throughput becomes the hard wall.

The data indicates that at 1080p, even with the relatively weak Arc B370, the system is likely hitting a CPU-imposed ceiling on frame generation. The Ryzen 5 7500X3D's high single-thread performance, evidenced by its Passmark single-thread score of 3494, helps keep minimum frame rates respectable even at high settings. However, the 4K results, where the Ultra preset manages only 70 FPS average, clearly show that the GPU's 20 ROPs and 40 TMUs are overwhelmed by the pixel fill requirements at that resolution. The 48.00 GPixel/s pixel rate and 96.00 GTexel/s texture rate are simply insufficient for 4K gaming at high quality levels.

GPU Role

The Intel Arc B370 is an integrated graphics processor based on the Xe3-LPG architecture, built on a 3 nm process by Intel. It operates with a base clock of 300 MHz and a boost clock of 2400 MHz, featuring 1280 shading units, 40 TMUs, and 20 ROPs. The memory configuration is entirely system-dependent, with the GPU relying on shared system memory rather than dedicated VRAM. This shared memory architecture means the bandwidth available to the GPU is contingent on the system's RAM configuration, which is a critical factor in this game's performance.

The GPU's raw compute capabilities are modest, with an FP32 throughput of 6.144 TFLOPS and FP16 of 12.29 TFLOPS. Its 3DMark Steel Nomad DX12 score of 1184 places it in the 5th percentile of all GPUs, and its nearest rivals in that benchmark are legacy parts like the ATI Mobility Radeon HD 5570 and ATI Radeon HD 5770, with delta percentages of -0.2% and -0.5% respectively. This is a clear indication that the Arc B370 is not designed for demanding gaming workloads, and the CS:GO results reflect this.

In CS:GO, the GPU's limitations become most apparent at 4K resolution. The difference between Low and Ultra settings at 4K is 41 FPS (111 FPS versus 70 FPS), which shows that the GPU struggles significantly when both resolution and graphical fidelity increase. At 1080p, the spread between Low and Ultra is 101 FPS (273 versus 172), a much larger absolute gap that suggests the CPU can still push high frame rates at lower settings, but the GPU cannot maintain those rates when shader complexity increases.

The 25 W TDP of the Arc B370 is remarkably low, and the fact that it has no power connectors and is listed as an IGP (integrated graphics processor) reinforces that this is not a discrete gaming solution. The GPU's boost clock of 2400 MHz is relatively high for an integrated part, but the memory bandwidth being "System Dependent" means that in a dual-channel DDR5 configuration with 83.2 GB/s available to the CPU, the GPU likely gets a fraction of that bandwidth for its own operations. This shared bandwidth is a likely contributor to the performance collapse at 4K.

Settings Recommendations

Given the measured data, the optimal settings for this combination depend heavily on the target resolution. At 1080p, the Low preset delivers 273 FPS average, which is 71 FPS higher than Medium and 101 FPS higher than Ultra. For competitive play where high frame rates are prioritized, Low settings at 1080p are the clear choice, as the jump from Low to Medium costs 40 FPS, while Medium to High costs another 31 FPS.

At 1440p, the Low preset provides 188 FPS, which is still well above the 144 Hz refresh rate common on many monitors. The Medium preset at 160 FPS is a reasonable middle ground, offering a 28 FPS penalty over Low but likely providing better visual clarity. The High preset at 139 FPS is acceptable for 120 Hz displays but sacrifices performance for marginal visual gains that are hard to notice in a fast-paced FPS.

At 4K, the situation is more constrained. The Low preset produces 111 FPS, which is the only settings level that breaks the 100 FPS barrier. Medium drops to 95 FPS, High to 82 FPS, and Ultra to 70 FPS. For a playable 4K experience, Low settings are effectively mandatory, and even then, the 111 FPS average may dip in heavy firefights given the minimum FPS of 80 recorded at Medium settings.

The data suggests that the Medium preset at 1080p (233 FPS) represents the best balance of visual quality and performance for most users, as it maintains frame rates high enough for any monitor while avoiding the lowest quality settings. However, for esports-focused players who prioritize maximum frame rates, Low at 1080p (273 FPS) is the superior choice. At 1440p, Medium (160 FPS) is the recommended preset, as it stays above 144 FPS and provides more visual detail than Low without the significant drop to High. For 4K, users should accept Low settings or consider lowering the resolution entirely.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are as follows: Low settings deliver 273 FPS, Medium delivers 233 FPS with a minimum of 198 and maximum of 268, High delivers 202 FPS, and Ultra delivers 172 FPS. The progression from Low to Ultra is a steady decline of approximately 30-40 FPS per settings tier, which indicates a balanced scaling where both CPU and GPU contribute to the frame rate.

At 2560x1440, Low settings produce 188 FPS, Medium produces 160 FPS with a minimum of 136 and maximum of 184, High produces 139 FPS, and Ultra produces 118 FPS. The gap between Low and Medium is 28 FPS, while the gap between Medium and High is 21 FPS, and High to Ultra is another 21 FPS. The reduction from 1080p to 1440p at each setting tier is approximately 31-33%, which is a consistent penalty that reflects the increased pixel count.

At 3840x2160, the results are: Low settings 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 drop from 1440p to 4K is more severe percentage-wise, with Low losing 77 FPS (41%), Medium losing 65 FPS (41%), High losing 57 FPS (41%), and Ultra losing 48 FPS (41%). This consistent 41% reduction across all settings tiers at 4K is a strong indicator that the GPU is the sole bottleneck at this resolution.

The minimum FPS data, available only for Medium settings, shows 198 FPS at 1080p, 136 FPS at 1440p, and 80 FPS at 4K. These minimums represent the 1% low frame rates that matter for smooth gameplay. At 1080p Medium, the minimum of 198 FPS is still exceptionally high, while at 4K Medium, the 80 FPS minimum means the game will occasionally dip below 80 FPS, which could cause visible stuttering on a 60 Hz display but is generally acceptable for CS:GO's gameplay style.

FAQ

Q: Is this system capable of running CS:GO at 144Hz?

A: At 1080p, yes. All settings presets exceed 144 FPS, with Low at 273 FPS, Medium at 233 FPS, High at 202 FPS, and Ultra at 172 FPS. At 1440p, only Low (188 FPS) and Medium (160 FPS) exceed 144 FPS, while High (139 FPS) and Ultra (118 FPS) fall short. At 4K, no preset reaches 144 FPS, with the highest being Low at 111 FPS.

Q: How does the Arc B370 compare to its nearest rivals in synthetic benchmarks?

A: In the 3DMark Steel Nomad DX12 test, the Arc B370 scores 1184. This is 0.2% lower than the ATI Mobility Radeon HD 5570 (1186), 0.5% lower than the ATI Radeon HD 5770 (1190), and 0.7% lower than the AMD Radeon HD 7650M (1192). It scores 1.4% higher than the AMD FirePro M2000 (1168). These are all legacy or low-power parts, indicating the Arc B370's limited performance class.

Q: What is the biggest performance drop between resolution steps?

A: The largest absolute drop is from 1080p to 1440p at Low settings, where frame rates fall from 273 FPS to 188 FPS, a loss of 85 FPS. The largest percentage drop is also in this transition, representing a 31% reduction. The 1440p to 4K transition at Low settings loses 77 FPS, which is a 41% reduction, making it the steepest relative decline per pixel added.

Q: Does the Ryzen 5 7500X3D bottleneck the Arc B370?

A: At 4K, no. The consistent 41% frame rate drop across all settings tiers from 1440p to 4K indicates the GPU is the limiting factor. At 1080p, the very high frame rates (273 FPS at Low) suggest the CPU's 6 cores and 12 threads with a 4.50 GHz boost clock are sufficient to feed the GPU, but the Arc B370's 25 W TDP and shared memory architecture prevent it from pushing beyond these levels.

Q: What is the best settings preset for competitive play?

A: For maximum frame rates, Low at 1080p provides 273 FPS, which is 71 FPS higher than Medium and 101 FPS higher than Ultra. This gives the greatest headroom above the 144 Hz threshold. If visual quality is a secondary concern, Medium at 1080p (233 FPS) still offers excellent performance while improving image quality over Low.

Q: How much slower is Ultra compared to Low at each resolution?

A: At 1080p, Ultra averages 172 FPS versus Low's 273 FPS, a difference of 101 FPS or 37% slower. At 1440p, Ultra averages 118 FPS versus Low's 188 FPS, a difference of 70 FPS or 37% slower. At 4K, Ultra averages 70 FPS versus Low's 111 FPS, a difference of 41 FPS or 37% slower. The consistent 37% penalty across resolutions confirms that the settings scaling is uniform, but the absolute cost in frame rate is higher at lower resolutions where the baseline is higher.

CPU Role

The AMD Ryzen 5 7500X3D is a 6-core, 12-thread processor from the 7000 series, built on TSMC's 5 nm process with a 71 mm² die size containing 11,270 million transistors. It operates at a base clock of 4.00 GHz and boosts to 4.50 GHz, with a 65 W TDP. The processor features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and a substantial 96 MB of shared L3 cache, which is the defining characteristic of the X3D series.

The CPU's performance in synthetic benchmarks is strong. It scores 3494 in Passmark single-thread tests and 25047 in multithread tests, with an average benchmark score of 44573. This places it in the 89th percentile of all CPUs. Its nearest rivals in average score are the Intel Core Ultra X9 388H (44466, 0.2% higher), Intel Core i9-13950HX (44342, 0.5% higher), AMD Ryzen AI Max 385 (44309, 0.6% higher), and Intel Core i5-14600 (44889, 0.7% lower). This indicates the 7500X3D is competitive with high-end mobile and desktop parts from both AMD and Intel.

In CS:GO, the CPU's role is most evident at 1080p where frame rates exceed 200 FPS across most settings. The high L3 cache of 96 MB is particularly beneficial for games like CS:GO that have smaller, more cache-sensitive workloads. The Passmark physics score of 2779 suggests adequate compute capability for game logic, while the floating-point math score of 43594 and integer math score of 70774 provide the raw processing power needed to maintain high frame rates.

However, the CPU's potential is not fully realized in this combination. At 4K, the frame rates are capped by the GPU, and even at 1080p, the Arc B370 cannot push frame rates high enough to fully stress the 7500X3D. The CPU's memory bandwidth of 83.2 GB/s over dual-channel DDR5 is shared with the GPU, which uses system memory for its frame buffer. This shared bandwidth could be a limiting factor in scenarios where both CPU and GPU are heavily active, but the measured data shows that the GPU's compute limitations manifest before any memory bandwidth contention becomes apparent.

The fact that this system ranks 2615th out of 2848 combos in CS:GO is a direct consequence of the GPU's 5th percentile ranking among all GPUs. The CPU, at the 89th percentile, is vastly more capable than the GPU. This imbalance is typical of integrated graphics solutions where a high-end processor is paired with a low-power IGP for non-gaming workloads. For CS:GO, this means users are essentially limited to the GPU's capabilities, and the CPU's 89th percentile standing cannot compensate for the Arc B370's weaknesses at higher resolutions.
