Counter-Strike: Global Offensive

# Counter-Strike: Global Offensive with Intel Core i5-12400F + NVIDIA GeForce RTX 5080

The pairing of Intel's 6-core Core i5-12400F with NVIDIA's flagship RTX 5080 produces frame rates that are almost absurdly high in Counter-Strike: Global Offensive, a 2012 FPS that scales across resolutions with unusual consistency. The measured data shows that this combination ranks in the 83rd percentile of 1,605 tested combos, placing it firmly in the upper echelon of systems for this title, though the CPU's role becomes increasingly apparent as resolution drops.

Resolution Scaling

The frame rate progression from 4K down to 1080p reveals a system that is clearly GPU-bound at the highest resolution but transitions into CPU-limited territory as pixel count falls. At 3840x2160 with High settings, the combo delivers 365 FPS. Dropping to 2560x1440 at the same settings pushes that figure to 612 FPS, a 67.7% improvement that indicates the GPU still has headroom. At 1920x1080 High, the average reaches 888.5 FPS, representing a 143.5% increase over the 4K result. This scaling pattern—where the 1440p to 1080p jump yields a 45.2% gain—suggests the RTX 5080 is still the primary limiter at 2560x1440, but the i5-12400F begins to constrain performance at 1080p.

The gap between Low and Ultra settings narrows dramatically as resolution decreases, which is a classic sign of CPU bottlenecking. At 4K, the spread from Low (494.1 FPS) to Ultra (309.5 FPS) is 184.6 FPS, a 59.6% difference. At 1440p, that spread grows to 313.4 FPS (833.9 Low versus 520.5 Ultra). At 1080p, the Low setting produces 1212.6 FPS while Ultra yields 760.3 FPS, a 452.3 FPS gap. The fact that even the lowest settings at 1080p cannot exceed roughly 1,213 FPS—while the RTX 5080's raw compute would suggest more—points to the 6-core processor as the ceiling.

How This Combo Ranks

Within the database of 1,605 tested CPU-GPU combinations for Counter-Strike: Global Offensive, this pairing ranks 83rd. That places it in the top 5.2% of all tested systems, which is notable given that the i5-12400F is a mid-range desktop processor while the RTX 5080 is a high-end graphics card. The ranking reflects the game's moderate CPU demands; CS:GO is not heavily threaded, so the i5's 6 cores and 12 threads are sufficient to feed the GPU at most settings.

The GPU alone sits at the 89th percentile among all tested graphics cards, with an average benchmark score of 59,188. Its nearest rivals in the GPU benchmark database include the Intel Arc A570M (58,239, 1.6% slower), the Intel Arc Pro A60 (60,326, 1.9% faster), and the Intel Arc A580 (57,756, 2.5% slower). The RTX 5080's PassMark G3D score of 36,565 and 3DMark Steel Nomad DX12 score of 8,637 reinforce its high-end positioning.

The CPU ranks at the 77th percentile among all processors, with an average benchmark score of 19,221. Its nearest rivals are the Intel Core i7-8700K (19,210, 0.1% slower), the Intel Core i5-1335U (19,167, 0.3% slower), and the AMD Ryzen 5 7533HS (19,364, 0.7% faster). This tight clustering means the i5-12400F is competitive with older high-end parts and newer mid-range mobile silicon.

CPU Role

The Intel Core i5-12400F is built on the Alder Lake architecture using a 10 nm process, with 6 cores and 12 threads. Its base clock of 2.50 GHz boosts to 4.40 GHz, and it carries 18 MB of shared L3 cache alongside 1.25 MB of L2 per core and 80 KB of L1 per core. These specifications explain why the processor scores 909 in 3DMark single-thread, 1,699 in 2-thread, and 5,912 in max-thread tests. The single-thread strength is critical for CS:GO, which relies heavily on one or two cores for game logic and draw call submission.

In Cinebench R23, the i5-12400F achieves 2,332 single-core and 16,518 multi-core. The Geekbench scores of 2,221 single-core and 9,138 multi-core further confirm balanced performance. PassMark results show 3,481 single-thread and 19,433 multi-thread scores, with floating-point math at 46,759 and integer math at 59,995. These numbers place the CPU just 0.1% ahead of the Core i7-8700K in average score, despite the older chip's higher frequency potential, and 1.3% ahead of the AMD EPYC 7773X.

For CS:GO specifically, the 4.40 GHz boost clock is the key asset. The measured FPS data shows that at 1080p Low, the system hits 1,212.6 FPS, which is likely near the CPU's maximum frame output for this engine. The multi-threaded scores (5,895 in 3DMark 16-thread, 19,433 in PassMark multi-thread) indicate the processor has enough headroom for background tasks, but the game's single-thread dependency is what ultimately caps performance at lower resolutions.

Measured FPS Breakdown

At 3840x2160, the RTX 5080 clearly dominates the workload. Low settings produce 494.1 FPS, Medium 418.2 FPS, High 365 FPS, and Ultra 309.5 FPS. The 4K results show a smooth progression where each settings tier costs roughly 10-15% performance. This is textbook GPU-bound behavior; the graphics card's 16 GB of GDDR7 memory and 960.0 GB/s bandwidth are fully utilized at this resolution.

Moving to 2560x1440, the numbers jump significantly. Low settings hit 833.9 FPS, Medium 706.6 FPS, High 612 FPS, and Ultra 520.5 FPS. The scaling from 4K to 1440p at Low settings is a 68.8% improvement, while Ultra improves by 68.2%. The consistency of these gains across settings suggests the GPU is still the primary bottleneck, but the CPU is starting to make its presence known—the gap between Low and Ultra at 1440p is 313.4 FPS compared to 184.6 FPS at 4K.

At 1920x1080, the CPU constraint becomes unmistakable. Low settings reach 1,212.6 FPS, Medium 1,027.3 FPS, High 888.5 FPS, and Ultra 760.3 FPS. The jump from 1440p Low to 1080p Low is 378.7 FPS (45.4%), but the jump from 1440p Ultra to 1080p Ultra is only 239.8 FPS (46.1%). More tellingly, the difference between 1080p Low and 1080p Ultra is 452.3 FPS, which means the GPU has enough headroom to render the scene at vastly different quality levels, yet the CPU cannot push frames beyond the low-setting ceiling.

GPU Role

The NVIDIA GeForce RTX 5080 is a Blackwell 2.0 architecture GPU built on TSMC's 5 nm process, with 45,600 million transistors on a 378 mm² die. Its 10,752 shading units, 336 TMUs, and 112 ROPs deliver a pixel rate of 293.1 GPixel/s and a texture rate of 879.3 GTexel/s. The 84 RT cores and 336 tensor cores provide 56.28 TFLOPS of FP32 compute, with FP16 at a 1:1 ratio. Boost clock runs at 2,617 MHz, and the 16 GB of GDDR7 memory operates at 1,875 MHz (30 Gbps effective) across a 256-bit bus for 960.0 GB/s bandwidth.

These specifications translate to a PassMark G3D score of 36,565 and a Geekbench OpenCL score of 264,461. The GPU's 3DMark Steel Nomad DX12 result of 8,637 places it among the fastest cards tested. Its nearest benchmark rivals are the Intel Arc A570M (1.6% slower), Intel Arc Pro A60 (1.9% faster), and Intel Arc A580 (2.5% slower), though these comparisons are based on average scores across all tests, not CS:GO specifically.

In CS:GO, the RTX 5080's role is to provide massive headroom. At 4K Ultra, the card still manages 309.5 FPS, which is far above the refresh rates of most displays. The 4K Low result of 494.1 FPS shows the GPU can handle even the most demanding pixel counts with ease. The fact that the system reaches 1,212.6 FPS at 1080p Low—while the GPU could theoretically render even more—demonstrates that the RTX 5080 is not the limiting factor at lower resolutions. Instead, the 16 GB VRAM and 960.0 GB/s bandwidth ensure that texture streaming and memory bandwidth never become bottlenecks, allowing the CPU to be the sole constraint. The GPU's 89th percentile ranking among all graphics cards, combined with the combo's 83rd rank in this specific game, confirms that the RTX 5080 is doing its part—the i5-12400F is the component holding back higher frame rates.
