Counter-Strike 2

Counter-Strike 2 with the AMD Ryzen 7 7700X and Intel Arc B390 presents a peculiar pairing: a high-end desktop CPU from 2022 driving an integrated-class GPU from 2026. The benchmark data shows a system that is almost entirely constrained by its graphics solution, yet the CPU’s headroom ensures that the Arc B390 is the sole bottleneck in nearly every scenario. This analysis breaks down the measured FPS across resolutions and settings, interprets the scaling patterns, and contextualizes the combo’s standing against 2,869 other tested pairings.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and consistent across all settings, confirming that the Intel Arc B390 is the limiting component. At Low settings, the measured average FPS falls from 179 at 1920x1080 to 118 at 2560x1440, a 34% reduction, and then to 66 at 3840x2160, a 63% drop from the 1080p baseline. This scaling pattern is typical for a GPU with limited fillrate and memory bandwidth, as the system-shared memory architecture struggles to feed the increased pixel count.

At High settings, the same trend emerges: 111 FPS at 1080p drops to 73 FPS at 1440p (a 34% decline) and then to 41 FPS at 4K (a 63% decline). The consistency of these percentage drops across settings is telling—it means the GPU is saturated at every resolution, and the CPU is never the limiting factor. If the Ryzen 7 7700X were the bottleneck, we would expect the FPS gap between 1080p and 1440p to narrow significantly, as the CPU would cap performance at lower resolutions.

The Ultra preset shows the most dramatic scaling, with 86 FPS at 1080p falling to 57 FPS at 1440p (a 34% drop) and then to 32 FPS at 4K (a 63% drop). This linear degradation suggests that the Arc B390’s 24 ROPs and 7.680 TFLOPS of FP32 compute are being fully utilized at all resolutions, with no spare headroom at any point. The data indicates that this combo is playable at 1080p for competitive settings, but 4K is only viable on Low settings, and even then, the 66 FPS average sits below the 144Hz threshold many CS2 players target.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo is at 1920x1080 with Medium settings. The Medium preset delivers 149 FPS average with a minimum of 126 FPS and a maximum of 171 FPS. This is the only settings/resolution combination that maintains an average above 144 FPS while also providing a minimum frame rate that stays above 120 FPS, which is critical for maintaining smooth gameplay in a fast-paced FPS.

The Low preset at 1080p achieves 179 FPS average, which is higher, but the visual fidelity loss may not be worth the extra 30 FPS, especially since the Medium preset’s minimum of 126 FPS is already well above the 100 FPS threshold most players consider acceptable. At 1440p, the Low preset (118 FPS) is the only playable option, but the minimum FPS data is missing, so there is no guarantee of frame time consistency. The High preset at 1080p (111 FPS) is viable but not ideal, as its average sits below the 120 FPS mark that many CS2 players prefer.

For 4K, the Low preset (66 FPS) is the only option that stays above 60 FPS, but this comes with significant visual compromises. The Medium preset at 4K (55 FPS average, 47 FPS minimum) is borderline playable but risks noticeable stutters in intense firefights. The Ultra preset should be avoided entirely; at 4K it averages 32 FPS, and even at 1080p it drops to 86 FPS, which is below the minimum acceptable frame rate for competitive play. The data suggests that Medium settings at 1080p is the sweet spot, offering the best balance of frame rate and visual quality without dipping below 120 FPS minimum.

GPU Role

The Intel Arc B390 is the defining component in this combo, and its specifications explain the measured results precisely. The GPU operates with a base clock of 300 MHz and a boost clock of 2500 MHz, which is a wide frequency range typical of an integrated graphics solution that dynamically scales based on thermal and power headroom. The 80 W TDP and IGP slot width confirm this is not a discrete card, but rather a processor-integrated GPU with no dedicated memory.

The memory configuration is "System Shared" across size, type, and bus width, with bandwidth listed as "System Dependent." This is the critical weakness: the GPU shares the Ryzen 7 7700X’s dual-channel DDR5 memory bus, which the CPU’s specifications cap at 83.2 GB/s. In a game like Counter-Strike 2, which relies heavily on draw calls and texture streaming, this shared bandwidth becomes the primary limitation, especially at higher resolutions where the pixel fillrate demands more memory traffic.

The GPU’s benchmark scores place it in the 9th percentile among all GPUs, with a 3DMark Steel Nomad score of 1482. Its nearest rivals are ancient NVIDIA parts: the GeForce GT 520MX (1463, 1.3% faster), the GeForce 800M (1460, 1.5% faster), the GeForce GT 625 OEM (1446, 2.5% faster), and the GeForce GT 710 (1443, 2.7% faster). This places the Arc B390 in the same performance tier as entry-level GPUs from over a decade ago, which aligns with the measured FPS: 179 FPS at 1080p Low is achievable because CS2 is not graphically demanding, but the GPU’s 24 ROPs and 48 TMUs limit its ability to push higher resolutions with complex geometry.

The FP32 performance of 7.680 TFLOPS and pixel rate of 60.00 GPixel/s are the theoretical limits, but the data shows the practical ceiling is far lower due to memory bandwidth constraints. The texture rate of 120.0 GTexel/s is adequate for 1080p, but at 4K, the GPU’s fillrate is insufficient, explaining the 63% FPS drop from 1080p to 4K across all settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. The Low preset averages 179 FPS, with no min/max data provided. Medium averages 149 FPS, with a minimum of 126 and maximum of 171. High averages 111 FPS, and Ultra averages 86 FPS. The spread from Low to Ultra is 93 FPS, indicating that the GPU is sensitive to settings changes at this resolution, but even the Ultra preset remains above 60 FPS.

At 2560x1440, the performance drops noticeably. Low averages 118 FPS, Medium averages 98 FPS (with a minimum of 84 and maximum of 113), High averages 73 FPS, and Ultra averages 57 FPS. The Low-to-Ultra spread narrows to 61 FPS, suggesting that the GPU is beginning to saturate at this resolution. The Medium preset’s minimum of 84 FPS is still playable, but the Ultra average of 57 FPS falls below the 60 FPS threshold.

At 3840x2160, the combo struggles. Low averages 66 FPS, Medium averages 55 FPS (with a minimum of 47 and maximum of 63), High averages 41 FPS, and Ultra averages 32 FPS. The Low-to-Ultra spread narrows further to 34 FPS, confirming that the GPU is fully maxed out. The Medium preset’s minimum of 47 FPS is below the 60 FPS target, and even the Low preset’s 66 FPS average leaves no headroom for frame time spikes.

The data shows a clear pattern: the GPU’s performance scales almost linearly with pixel count, with no evidence of CPU limiting at any resolution. The Ryzen 7 7700X’s 8 cores and 16 threads are more than sufficient to feed the Arc B390, even at 1080p Low where the GPU is pushing 179 FPS.

How This Combo Ranks

The combo ranks 2535th out of 2870 tested combinations, placing it in the bottom 12% of all CPU-GPU pairings. This rank reflects the GPU’s severe limitations, not the CPU’s capabilities. The Ryzen 7 7700X is a high-end processor with an average benchmark score of 35909, placing it in the 85th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 7 PRO 5845 (35802, 0.3% slower), the Intel Core 7 250H (35728, 0.5% slower), the AMD Ryzen AI 7 PRO 350 (35719, 0.5% slower), and the Intel Core Ultra 9 185H (35670, 0.7% slower). This CPU is clearly not the bottleneck.

In contrast, the GPU’s average benchmark score of 1482 places it in the 9th percentile, with its nearest rivals being the GT 520MX (1463, 1.3% slower), the GeForce 800M (1460, 1.5% slower), the GT 625 OEM (1446, 2.5% slower), and the GT 710 (1443, 2.7% slower). The combo’s rank of 2535 is almost entirely determined by the GPU, as the CPU’s performance headroom cannot compensate for the GPU’s lack of raw compute and memory bandwidth.

The rank of 2535 out of 2870 means there are 335 tested combos that perform worse, likely those pairing similarly weak GPUs with even older CPUs. However, the data suggests that upgrading the GPU would drastically improve this combo’s rank, as the Ryzen 7 7700X has ample headroom to support a much more powerful graphics card. In CS2 specifically, the CPU’s strong single-thread performance (1987 in Cinebench R23 single-core) ensures that any GPU upgrade would result in a near-linear FPS improvement, unlike a weaker CPU that would become the new bottleneck.

CPU Role

The AMD Ryzen 7 7700X is a Zen 4 (Raphael) processor built on TSMC’s 5 nm process, with 8 cores and 16 threads. It has a base clock of 4.50 GHz and a boost clock of 5.40 GHz, with a 105 W TDP. The CPU features 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. Its memory support is DDR5 with a dual-channel bus, and its 83.2 GB/s memory bandwidth is shared with the integrated Arc B390 GPU.

In Counter-Strike 2, the CPU’s role is to handle game logic, physics, and draw call submission, which benefits from strong single-thread performance. The 7700X delivers a Cinebench R23 single-core score of 1987, which is excellent, and this is reflected in the measured FPS: at 1080p Low, the GPU is pushing 179 FPS, and there is no indication that the CPU is holding it back. If the CPU were the bottleneck, we would expect the FPS to remain constant regardless of resolution, but the data shows a clear 63% drop from 1080p to 4K, which is purely GPU-limited.

The CPU’s multi-threaded performance is also strong, with a Cinebench R23 multi-core score of 19088 and a Geekbench multi-core score of 12451. In a game like CS2, which can utilize multiple threads for asset streaming and audio processing, the 7700X’s 16 threads provide ample headroom. The 3DMark 16-thread score of 8859 and 8-thread score of 7057 indicate that the CPU scales well with thread count, but the game’s primary thread is more important, and the single-thread score of 1090 in 3DMark confirms its strength.

The CPU’s memory bandwidth of 83.2 GB/s is a double-edged sword in this combo. While it is sufficient for the CPU’s own needs, the Arc B390’s reliance on system memory means the GPU competes with the CPU for the same bandwidth. However, the data shows that this contention is not severe enough to cause CPU-side stuttering, as the minimum FPS at 1080p Medium is 126 FPS, which is well above playable thresholds. The CPU’s integrated Radeon Graphics is not used in this combo, but its presence does not impact the dedicated Arc B390’s performance.

Ultimately, the Ryzen 7 7700X is a capable gaming CPU that is wasted on this GPU. Its 85th percentile ranking among all CPUs and its nearest rivals (all within 0.7% of its average score) show that it is a top-tier processor. The combo’s poor rank of 2535 out of 2870 is entirely attributable to the Arc B390, and anyone using this setup for CS2 should consider the GPU the primary upgrade path, as the CPU will not become the bottleneck even at 1080p Low with a much faster graphics card.
