Counter-Strike 2

Counter-Strike 2 is notoriously sensitive to both CPU and GPU performance, and this specific pairing of an Intel Core i5-11400F with an NVIDIA GeForce RTX 5080 creates a fascinating bottleneck profile. The data shows a combo that can push massive frame rates at lower resolutions, but the scaling curve reveals where the processor begins to hold back the graphics card. This analysis breaks down the measured performance across resolutions and settings, interpreting what the numbers mean for actual gameplay.

Resolution Scaling

The measured FPS data reveals a classic pattern of diminishing returns as resolution increases, but with an unusual twist at the top end. At 1080p with Low settings, the combo achieves 597.4 FPS, which drops to 475.1 FPS at 1440p and then falls sharply to 264.6 FPS at 4K. This represents a 20.5% drop from 1080p to 1440p, but a much steeper 44.3% drop from 1440p to 4K. The scaling suggests that at 1080p, the system is heavily CPU-bound, as the RTX 5080 has ample headroom to render frames far faster than the i5-11400F can feed it.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the difference between Low (597.4 FPS) and Ultra (341.6 FPS) is 255.8 FPS. At 4K, that gap grows to 139.7 FPS between Low (264.6 FPS) and Ultra (124.9 FPS). This indicates that at 4K, the GPU becomes the limiting factor, and turning down settings yields proportionally larger gains. The 4K Ultra result of 124.9 FPS is still highly playable, but it shows that this combination is not designed for maximum visual fidelity at 4K in this title.

What is most telling is the 4K High result of 165.9 FPS versus the 4K Medium result of 219.8 FPS. The jump from High to Medium provides a 53.9 FPS improvement, which is more significant than the 45.8 FPS gain from Ultra to High. This suggests that the Medium preset hits a sweet spot where the GPU workload drops enough to let the CPU keep up more effectively. The data indicates that for competitive play, dropping to 1440p Medium (394.1 FPS) or even 1080p High (440.3 FPS) provides far more headroom than any 4K configuration.

GPU Role

The RTX 5080 brings substantial hardware to this pairing, with 16 GB of GDDR7 memory on a 256-bit bus delivering 960.0 GB/s of bandwidth. The card’s boost clock of 2617 MHz and 10752 shading units provide raw compute power that is largely underutilized at lower resolutions. The benchmark results confirm this: the GPU achieves a 3DMark Steel Nomad DX12 score of 8637 and a Passmark G3D score of 36565, placing it in the 89th percentile of all GPUs. Yet in Counter-Strike 2 at 1080p, the frame rates are capped by the CPU rather than the GPU.

The VRAM capacity is not a limiting factor in this game, as Counter-Strike 2’s textures and geometry are modest compared to modern AAA titles. The 16 GB allocation is more than sufficient even at 4K Ultra settings, where the measured 124.9 FPS indicates the GPU is working hard but not running out of memory. The card’s 56.28 TFLOPS FP32 performance and 879.3 GTexel/s texture rate are far beyond what this game requires, which is why the GPU’s percentile rank of 89th overall does not translate to proportional frame rate advantages in this specific title.

The GPU’s memory clock of 1875 MHz (30 Gbps effective) and pixel rate of 293.1 GPixel/s are impressive on paper, but the 4K results show that the card is capable of much higher output than the CPU can support. At 4K Low, the 264.6 FPS result is likely close to the CPU’s maximum frame generation capability, as the GPU has minimal work to do at those settings. The RTX 5080’s performance is therefore best utilized at 4K with higher settings, where the GPU workload increases and the CPU bottleneck becomes less pronounced.

How This Combo Ranks

In the database of tested combos for Counter-Strike 2, this pairing ranks 89th out of 1632 combinations. This places it in the top 5.5% of all tested configurations, which is a strong result given that the CPU is a mid-range part from 2021. The ranking reflects the GPU’s dominance in the pairing, as the RTX 5080’s high percentile (89th) pulls the combo upward despite the i5-11400F’s more modest 75th percentile ranking among all CPUs.

The combo rank of 89 suggests that there are 88 other combinations that outperform this one in Counter-Strike 2, likely featuring newer or higher-end CPUs paired with similar or better GPUs. However, the measured frame rates show that this combo is far from a bottleneck disaster. At 1080p Medium, it produces 556.6 FPS, which is well beyond what any current display can show. The rank indicates that while the CPU limits peak performance, the overall experience remains excellent.

Comparing the CPU to its nearest rivals in the benchmark database shows that the i5-11400F is competitive with much newer mobile parts. Its average benchmark score of 17181 is nearly identical to the AMD Ryzen 7 5700U (17189, 0% delta) and the Intel Core i7-1260P (17212, -0.2% delta). This suggests that the CPU’s performance in synthetic tests is not the limiting factor; rather, it is the architectural efficiency in gaming workloads. The GPU’s nearest rivals, such as the Intel Arc A570M (58239, 1.6% delta) and the Arc Pro A60 (60326, -1.9% delta), are far below the RTX 5080’s capability, confirming that the GPU is the dominant component in this pairing.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional performance across all settings. Low settings produce 597.4 FPS, Medium drops to 556.6 FPS, High yields 440.3 FPS, and Ultra manages 341.6 FPS. The difference between Low and Ultra is 255.8 FPS, showing that even at maximum settings, the frame rate remains well above competitive thresholds. The 1080p results are clearly CPU-bound, as the GPU has minimal work at this resolution.

Moving to 2560x1440, the frame rates remain high but show a noticeable scaling effect. Low settings produce 475.1 FPS, Medium drops to 394.1 FPS, High yields 293.4 FPS, and Ultra manages 228.2 FPS. The drop from 1080p Low to 1440p Low is 122.3 FPS (20.5%), which is more than the 81 FPS drop from 1440p Low to 4K Low (30.7%). This indicates that the CPU bottleneck is less severe at 1440p, allowing the GPU to start contributing more to frame generation.

At 3840x2160, the GPU becomes the primary limiter. Low settings produce 264.6 FPS, Medium drops to 219.8 FPS, High yields 165.9 FPS, and Ultra manages 124.9 FPS. The 4K Ultra result is the only configuration below 144 FPS, which is notable for competitive play. The scaling from 1440p Ultra (228.2 FPS) to 4K Ultra (124.9 FPS) represents a 45.3% drop, confirming that the GPU is now the bottleneck. The 4K Medium result of 219.8 FPS is the most balanced config for high-resolution play, offering smooth performance without sacrificing too much visual quality.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. Its 12 MB of shared L3 cache and dual-channel DDR4 memory support (51.2 GB/s bandwidth) are adequate for gaming, but the 14 nm process node and 2021 release date place it behind newer designs. In synthetic benchmarks, the CPU scores 14372 in Cinebench R23 multi-core and 2029 in single-core, which is respectable but not class-leading.

In Counter-Strike 2, the CPU’s role is critical at lower resolutions and settings. The 1080p Low result of 597.4 FPS is likely near the CPU’s maximum frame generation limit, as the GPU has minimal work at those settings. The CPU’s 6 cores and 12 threads are sufficient for this game, which does not scale well beyond 4-6 threads. The single-core performance, as measured by a Geekbench single-core score of 1979, is the more important metric here.

The CPU’s performance relative to its rivals confirms that it is not a weak link in absolute terms. Its average benchmark score of 17181 is within 0.2% of the Intel Core i7-1260P and the Core Ultra 7 164U, both of which are more recent parts. However, the i5-11400F’s lack of support for DDR5 and PCIe 5.0 (it only supports PCIe Gen 4 with 20 lanes) may limit its ability to feed the RTX 5080’s PCIe 5.0 interface. Despite this, the measured results show that the combo still delivers excellent frame rates, suggesting that the PCIe bandwidth difference is not a significant bottleneck in this game.
