Counter-Strike 2

Counter-Strike 2 with an AMD Ryzen 5 2600 and NVIDIA GeForce RTX 3070 presents a dataset where the CPU is the dominant variable. The measured frames per second (FPS) reveal a system that scales dramatically with resolution, but whose ceiling is consistently capped by the processor's Zen architecture. This analysis interprets the measured rows to explain where the bottleneck sits and how the hardware behaves across the four tested presets.

Resolution Scaling

The FPS drop from 1080p to 4K is steep, but the shape of that drop is revealing. At Low settings, the average FPS falls from 432.9 at 1920x1080 to 285.4 at 2560x1440, then to 158.5 at 3840x2160. That is a 37.7% reduction from 1080p to 1440p, and a further 44.5% reduction from 1440p to 4K. This pattern indicates that at lower settings, the workload is shifting from the CPU to the GPU as pixel count rises, but the CPU is still not the primary limiter at 1440p.

The High preset tells a different story. At 1080p High, the system produces 271.6 FPS, which drops to 178.1 at 1440p and then to 102.0 at 4K. The percentage drop from 1080p to 1440p is 34.4%, and from 1440p to 4K it is 42.7%. Compare this to the Ultra preset: 210.2 FPS at 1080p, 137.8 at 1440p, and 76.6 at 4K. The Ultra curve shows the smallest relative drop between 1080p and 1440p (34.4%), but the largest absolute penalty at 4K, where it barely holds above 60 FPS.

The key insight is that the delta between Low and Ultra at 1080p is 222.7 FPS (432.9 versus 210.2), while at 4K that delta narrows to 81.9 FPS (158.5 versus 76.6). This compression at higher resolutions confirms that the GPU is being saturated at 4K, whereas at 1080p the CPU is leaving performance on the table. The RTX 3070, with its 8 GB of GDDR6 memory and 448.0 GB/s bandwidth, is clearly capable of far more at 1080p than the Ryzen 5 2600 can feed it.

CPU Role

The Ryzen 5 2600 is a 6-core, 12-thread processor with a base clock of 3.40 GHz and a boost clock of 3.90 GHz. Its architecture is Zen, built on a 12 nm process. The benchmark data for this CPU shows a Cinebench R23 multi-core score of 11186 and a single-core score of 1579. These numbers place it in the 77th percentile of all CPUs, with an average benchmark score of 19616. Its nearest rivals include the Intel Core i5-1345U (deltaPct -0.4) and the AMD Ryzen 5 7530U (deltaPct 0.6), meaning the 2600 is statistically tied with those parts in general compute.

For Counter-Strike 2, which is a CPU-bound title at high frame rates, the single-thread performance matters most. The Cinebench R23 single-core score of 1579 is modest by modern standards, and the data shows the consequence. At 1080p Low, the system hits 432.9 FPS, which is high, but the RTX 3070 is likely capable of more. The gap between Low and Medium at 1080p is 71.6 FPS (432.9 versus 361.3), and the gap between Medium and High is 89.7 FPS (361.3 versus 271.6). These are large performance cliffs, suggesting that the CPU is struggling to maintain frame pacing as the game’s render workload increases.

The processor’s 16 MB of shared L3 cache and dual-channel DDR4 memory support (with 46.9 GB/s bandwidth) are not highlighted in the FPS data, but the overall trend is clear: the 2600 is the bottleneck in this pairing. The CPU’s benchmark percentile (77) is actually higher than the GPU’s percentile (72), yet the game results show the CPU limiting the GPU’s potential at lower resolutions.

Settings Recommendations

Based on the measured rows, the best experience depends on the target resolution and refresh rate. At 1080p, the Medium preset delivers 361.3 FPS, which is 89.7 FPS higher than High (271.6) and 151.1 FPS higher than Ultra (210.2). The jump from Medium to Low is 71.6 FPS, but Low yields 432.9 FPS. For competitive play on a 240 Hz monitor, Low is the only preset that can fully saturate that refresh rate, though Medium is a strong balance of visual fidelity and performance.

At 1440p, Medium produces 237.2 FPS, which is 59.2 FPS ahead of High (178.1) and 99.4 FPS ahead of Ultra (137.8). The Low preset at 1440p hits 285.4 FPS, but the visual downgrade is substantial. For a 165 Hz panel, Medium is the sweet spot, as it exceeds the refresh rate with a comfortable margin. High at 1440p is also viable, but the 59.2 FPS penalty versus Medium is steep for the visual gain.

At 4K, the situation flips. Ultra drops to 76.6 FPS, which is below the 100 FPS threshold that many competitive players consider smooth. High at 102.0 FPS is playable, but Medium at 131.6 FPS is the most balanced choice. Low at 158.5 FPS is optimal for high-refresh 4K monitors, but the game’s visual quality at Low is notably reduced. The data suggests that for 4K, Medium is the recommended preset, as it provides 131.6 FPS while maintaining most of the game’s visual features.

How This Combo Ranks

In the database of tested combinations, this CPU-GPU pairing ranks 750th out of 1632 combos for Counter-Strike 2. That puts it in the 54th percentile of all tested systems, which is lower than the individual hardware percentiles would suggest. The RTX 3070 alone sits in the 72nd percentile of all GPUs, and the Ryzen 5 2600 in the 77th percentile of all CPUs. The combination ranking of 750/1632 indicates that the pairing is suboptimal for this specific game, as the CPU drags the GPU down.

The nearest rivals for the GPU include the AMD Radeon RX 6600 XT (deltaPct 0.9) and the NVIDIA GeForce GTX 980 Ti (deltaPct 1), meaning the RTX 3070 is roughly on par with those cards in synthetic benchmarks. However, in Counter-Strike 2, the system’s 1080p Low score of 432.9 FPS is the highest measured, but it is the only preset that approaches the CPU’s limit. The combo ranking of 750 suggests that many other CPU-GPU pairs, perhaps with faster single-threaded processors, achieve better frames despite having weaker GPUs in theory.

The gap between the CPU’s percentile (77) and the combo’s percentile (54) is a 23-point drop, which is a strong signal of a bottleneck. In contrast, the GPU’s percentile (72) is closer to the combo’s percentile, but the CPU is still the limiting factor in most of the measured scenarios.

GPU Role

The NVIDIA GeForce RTX 3070 is built on the Ampere architecture with a GA104 chip, featuring 5888 shading units, 184 texture mapping units, and 96 raster output units. Its boost clock is 1725 MHz, and it has 8 GB of GDDR6 memory on a 256-bit bus, yielding 448.0 GB/s of bandwidth. The GPU’s benchmark scores are strong: a Passmark G3D score of 22214 and a 3DMark Steel Nomad DX12 score of 3162. Its percentile vs all GPUs is 72, and its average benchmark score is 28238.

In this dataset, the GPU’s role is to provide headroom that the CPU cannot use. At 1080p Low, the RTX 3070 is likely idle much of the time, waiting for the CPU to deliver draw calls. The measured 432.9 FPS is impressive, but the fact that 4K Ultra only drops to 76.6 FPS (a 356.3 FPS difference) shows that the GPU has enough power to handle the game’s highest settings at 4K, just not at high frame rates. The GPU’s 8 GB VRAM is sufficient for this game, as the settings do not appear to cause texture thrashing.

The GPU’s nearest rival, the AMD Radeon RX 6600 XT, has a deltaPct of 0.9, meaning the RTX 3070 is slightly slower in synthetic tests. Yet in real gaming, the RTX 3070’s higher bandwidth (448.0 GB/s) and more shading units (5888) should give it an edge. The data shows that the GPU is not the limiting component until 4K, where the Ultra preset’s 76.6 FPS suggests the GPU is finally being pushed.

Measured FPS Breakdown

At 1920x1080, the full range of settings shows the CPU constraint. Low averages 432.9 FPS, Medium drops to 361.3, High to 271.6, and Ultra to 210.2. The step from Low to Medium is 71.6 FPS, Medium to High is 89.7, and High to Ultra is 61.4. These are large deltas, all pointing to the CPU’s single-thread limits.

At 2560x1440, the same pattern holds but with lower absolute numbers. Low averages 285.4 FPS, Medium 237.2, High 178.1, and Ultra 137.8. The deltas are 48.2 (Low to Medium), 59.1 (Medium to High), and 40.3 (High to Ultra). The relative penalties are similar to 1080p, but the total FPS is lower, indicating the GPU is starting to share the load.

At 3840x2160, the GPU becomes the primary bottleneck. Low averages 158.5 FPS, Medium 131.6, High 102.0, and Ultra 76.6. The deltas shrink to 26.9 (Low to Medium), 29.6 (Medium to High), and 25.4 (High to Ultra). The fact that the High to Ultra delta is nearly constant across resolutions (61.4 at 1080p, 40.3 at 1440p, 25.4 at 4K) shows that the GPU is handling the extra detail without much penalty at 4K, but the absolute FPS is too low for competitive play.

Notably, the Low preset at 4K (158.5 FPS) is higher than the Ultra preset at 1440p (137.8 FPS). This crossover point demonstrates that resolution scaling is more punishing than settings scaling for this GPU. The measured data consistently shows that the RTX 3070 can handle 4K Low with ease, but the CPU prevents the system from achieving high frame rates at 1080p with any preset other than Low. The system’s overall performance is thus defined by a 6-core, 12-thread CPU that was released in 2018, paired with a 2020 GPU that is end-of-life but still potent.
