Counter-Strike 2

# How This Combo Ranks

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 4080 lands at rank 237 out of 3,719 tested combos in Counter-Strike 2. This places the combination in the top 6.4% of all tested systems, a strong showing for a CPU that sits at the 77th percentile among all processors and a GPU at the 86th percentile among all graphics cards. The rank indicates that this pairing is well-balanced for CS2's specific demands, though it is not at the very top of the leaderboard — there are 236 combinations that deliver higher average frame rates in this title.

The delta between this combo's CPU and its nearest rivals is remarkably tight. The Ryzen 5 8400F's average benchmark score of 25,005 is just 0.2% ahead of the AMD Ryzen 5 7500F (24,964) and 0.3% ahead of the Intel Core i7-11850H (24,935). Interestingly, the AMD EPYC 9474F scores 0.4% higher (25,103), yet that server-class chip would unlikely appear in a gaming rig. This clustering suggests that the 8400F is delivering performance right at the expected level for its class — no surprises, but no headroom above its direct competitors either.

On the GPU side, the RTX 4080's average benchmark score of 54,247 is nearly identical to the RTX 4080 SUPER's 54,209 (0.1% difference). The AMD Radeon Pro W5700X scores 1.1% higher (54,828), while the Radeon RX 6750 GRE 12 GB and Radeon 8060S are 2.6% and 2.7% ahead respectively. These are all within a 3% band, indicating that the RTX 4080 is performing at the upper edge of its tier, with no single rival clearly dominating it in synthetic workloads.

GPU Role

The RTX 4080 brings 16 GB of GDDR6X memory on a 256-bit bus, delivering 716.8 GB/s of bandwidth. In Counter-Strike 2, this memory configuration is far beyond what the game requires at any resolution — CS2 is not a VRAM-intensive title, and the 16 GB allocation means there is virtually no risk of hitting memory capacity limits even at 4K Ultra settings. The card's memory clock runs at 1400 MHz with 22.4 Gbps effective speed, a fast configuration that helps maintain consistent frame delivery in scenes with many dynamic objects.

The GPU's base clock of 2205 MHz and boost clock of 2505 MHz are the operative numbers for CS2 performance. The boost clock is particularly relevant because Counter-Strike 2 tends to stress the GPU less than many modern AAA titles, allowing the card to sustain near-boost frequencies for extended periods. The architecture is Ada Lovelace on a 5 nm process from TSMC, which contributes to the card's efficiency — though the 320 W TDP indicates it still draws substantial power under load.

With 9,728 shading units, 304 TMUs, and 112 ROPs, the RTX 4080 has ample raw compute for CS2's relatively modest graphical demands. The 76 RT cores and 304 tensor cores are largely idle in this game, as CS2 does not heavily utilize ray tracing or DLSS features. This means the GPU's real-world performance in CS2 is driven primarily by its rasterization throughput: 48.74 TFLOPS of FP32 compute and a texture rate of 761.5 GTexel/s. The pixel rate of 280.6 GPixel/s helps explain why even at 4K, the card maintains triple-digit frame rates.

The measured FPS data supports the interpretation that the GPU is not the limiting factor at lower resolutions. At 1080p Low, the combo achieves 674 FPS average — a figure that far exceeds what any display can show and suggests the CPU is the bottleneck at that point. The GPU's role becomes more prominent as resolution increases, but even at 4K Ultra, the 120 FPS average indicates the card is handling the load without being overwhelmed.

CPU Role

The Ryzen 5 8400F is a 6-core, 12-thread processor based on Zen 4 architecture (Phoenix codename) built on TSMC's 4 nm process. Its base clock of 4.20 GHz and boost clock of 4.70 GHz are competitive for gaming workloads, and the 16 MB of shared L3 cache (plus 1 MB L2 per core and 64 KB L1 per core) provides a solid foundation for CS2's simulation and entity-update tasks. The CPU's 65 W TDP is modest, but the data shows it does not hold back the RTX 4080 in most scenarios.

Counter-Strike 2 is known to be more CPU-sensitive than many other FPS titles due to its tick-rate-based server logic and the need to process many entity updates per frame. The 8400F's single-thread performance is critical here — its 3DMark single-thread score of 951 and Cinebench R23 single-core score of 2,943 indicate strong per-core throughput. The multi-thread scores (3DMark max threads: 6,165; Cinebench R23 multi-core: 20,851) show that the processor can also leverage its 12 threads when needed, though CS2 typically scales better with single-core speed than with core count.

The CPU's percentile rank of 77 among all processors puts it in the upper quartile, and its average benchmark score of 25,005 places it between several capable rivals. The nearest rival data shows the 8400F essentially ties the Ryzen 5 7500F (0.2% faster), which is notable because the 7500F is often considered a dedicated gaming CPU. This suggests the 8400F's Phoenix architecture — which includes a more integrated design than the 7500F's Raphael — does not sacrifice gaming performance in CS2.

The measured FPS numbers reveal the CPU's influence most clearly at 1080p. The jump from 674 FPS at Low settings to 560 FPS at Medium shows that even modest graphical increases begin to engage the GPU more, but the massive 1080p numbers overall indicate the CPU is feeding frames faster than the GPU can render them at lower settings. At 4K, the CPU's role diminishes as the GPU becomes the primary constraint, but the 8400F still provides enough headroom to keep the RTX 4080 fed at 249 FPS on Low settings at 4K.

The 8400F supports DDR5 memory with dual-channel configuration and 83.2 GB/s bandwidth, which is adequate for CS2's memory access patterns. The 20 PCIe Gen 4 lanes provide sufficient bandwidth for the RTX 4080's PCIe 4.0 x16 interface, ensuring no bottleneck from the data path between CPU and GPU.

FAQ

Q: Why does the combo rank 237th out of 3,719 tested combinations if the CPU and GPU are both in the top quartile of their respective categories?

A: The rank reflects the specific performance in Counter-Strike 2, not synthetic benchmarks. While the CPU sits at the 77th percentile and the GPU at the 86th percentile, the game's engine places particular demands on single-thread CPU performance and memory latency. The 237th rank out of 3,719 (top 6.4%) indicates that many other combinations — likely with higher-clocked CPUs or more cache — edge out this pairing in CS2 specifically, even if the overall hardware is strong.

Q: How does the Ryzen 5 8400F compare to its closest rival, the Ryzen 5 7500F?

A: The average benchmark scores are nearly identical: 25,005 for the 8400F versus 24,964 for the 7500F, a difference of just 0.2%. In practical terms, this means the two CPUs are interchangeable for CS2 performance. The 8400F's Phoenix architecture and the 7500F's design deliver virtually the same throughput in both synthetic tests and likely in-game, making the choice between them dependent on other factors like platform features rather than raw gaming performance.

Q: Is the RTX 4080's 16 GB VRAM necessary for Counter-Strike 2?

A: No. CS2 is not a VRAM-intensive game, and even at 4K Ultra settings, the game likely uses well under 8 GB. The 16 GB GDDR6X allocation is future-proofing and benefits other titles, but for CS2 specifically, the memory capacity is not a limiting factor. The card's bandwidth (716.8 GB/s) and clock speeds are what matter for this game, and those are more than sufficient to maintain high frame rates.

Q: Why does the 1080p Low setting achieve 674 FPS while 4K Ultra drops to 120 FPS?

A: This 5.6x difference highlights the shift in bottleneck. At 1080p Low, the CPU (Ryzen 5 8400F) is the limiting component, delivering frames as fast as its single-thread performance allows — 674 FPS. As resolution increases, the GPU (RTX 4080) becomes the constraint, and at 4K Ultra, the card's rasterization throughput caps out at 120 FPS. The CPU has ample headroom at higher resolutions, as evidenced by the 249 FPS at 4K Low, which is still CPU-limited.

Q: What does the GPU's 86th percentile rank mean for CS2 playability?

A: The 86th percentile indicates the RTX 4080 outperforms 86% of all GPUs in the database. For CS2, this translates to playable frame rates at every resolution and setting combination measured — the lowest recorded average is 120 FPS at 4K Ultra. Competitive players targeting 240+ FPS can achieve that at 1080p Medium (560 FPS) or 1440p Low (446 FPS), while 4K High (155 FPS) remains smooth for casual play.

Q: How does the CPU's TDP of 65 W influence its performance in CS2?

A: The 65 W TDP is low for a desktop CPU, but the data shows it does not hinder CS2 performance. The 4.70 GHz boost clock is sustained effectively under gaming loads, and the CPU's 77th percentile rank confirms it performs above average. The modest power draw also means less heat and potentially more stable boost behavior during extended gaming sessions, which can benefit frame time consistency.

Resolution Scaling

The measured FPS data across resolutions reveals a clear pattern of CPU limitation at lower resolutions transitioning to GPU limitation at higher ones. At 1080p, the average FPS across settings ranges from 325 (Ultra) to 674 (Low), with a spread of 349 FPS between the lowest and highest settings. This wide spread at 1080p indicates the GPU is being underutilized at Low settings (674 FPS) and only becomes fully engaged at Ultra (325 FPS), where the additional graphical work finally loads the RTX 4080 more heavily.

Moving to 1440p, the FPS range tightens to 215–446 across settings. The drop from 1080p to 1440p at Low settings is 34% (from 674 to 446 FPS), while at Ultra settings the drop is 34% as well (from 325 to 215 FPS). This consistent reduction suggests the GPU is becoming more of a factor at 1440p, but the CPU still plays a significant role, particularly at Low settings where 446 FPS indicates remaining CPU headroom.

At 4K, the range compresses further to 120–249 FPS. The transition from 1440p to 4K shows a 44% drop at Low settings (446 to 249 FPS) and a 44% drop at Ultra (215 to 120 FPS). This steeper decline at 4K confirms the GPU is now the primary bottleneck. The RTX 4080's pixel rate of 280.6 GPixel/s and texture rate of 761.5 GTexel/s are being pushed closer to their limits at this resolution, particularly at Ultra settings where 120 FPS is the ceiling.

The pattern across all three resolutions shows that the 8400F can deliver well over 400 FPS in CS2 when unconstrained, while the RTX 4080's maximum output at 4K is around 250 FPS even at Low settings. The limiting component shifts from CPU at 1080p to GPU at 4K, with 1440p representing a balanced zone where both components contribute meaningfully to the final frame rate.

Settings Recommendations

The measured data provides clear guidance for different use cases. For competitive play at 1080p, Low settings deliver the highest average FPS at 674, which exceeds the refresh rate of virtually any monitor. However, the jump from Low to Medium at 1080p (674 to 560 FPS) is only a 17% reduction while providing improved visual clarity — this is likely the sweet spot for players who want both high frame rates and better visibility. Medium at 1080p also shows a minimum FPS of 476, ensuring no drops below typical 360 Hz display refresh rates.

For 1440p users, Medium settings at 371 FPS average (315 FPS minimum) offers the best balance of visual quality and performance. This is a 17% drop from Low (446 FPS) but a 73% improvement over Ultra (215 FPS). The 315 FPS minimum ensures smooth gameplay even in intense firefights, and the visual upgrade from Low to Medium is noticeable in CS2's updated rendering. High settings at 277 FPS average is also viable for those with 240 Hz displays, though the minimum FPS is not recorded in the data.

At 4K, High settings at 155 FPS average provide the best experience for those with high-refresh-rate 4K monitors. The drop from Medium (207 FPS) to High (155 FPS) is a 25% reduction, but High offers better visual fidelity for a game played on a large screen. Ultra at 120 FPS is playable but close to the threshold where input latency becomes noticeable for competitive play. Low at 249 FPS is the fastest option at 4K, but the visual compromise is severe for a game that relies on visual clarity for enemy detection.

The data suggests Medium settings across all resolutions offer the most balanced experience — 560 FPS at 1080p, 371 FPS at 1440p, and 207 FPS at 4K. This setting tier provides a consistent visual baseline while maintaining frame rates that satisfy both competitive and casual players. The minimum FPS values recorded for Medium (476 at 1080p, 315 at 1440p, 176 at 4K) confirm that this setting avoids major frame drops, which is critical for maintaining aim consistency.

Measured FPS Breakdown

At 1920x1080 resolution, the measured average FPS values across settings are: Low 674, Medium 560 (minimum 476, maximum 644), High 418, and Ultra 325. The progression from Low to Ultra shows a 52% reduction in average FPS, but even the lowest value (325 FPS at Ultra) far exceeds the refresh rate of most gaming monitors. The Medium setting's minimum of 476 FPS is particularly notable, as it guarantees frame delivery above even 480 Hz displays during the most demanding scenes.

For 2560x1440 resolution, the averages are: Low 446, Medium 371 (minimum 315, maximum 426), High 277, and Ultra 215. The drop from 1080p to 1440p is consistent across settings, with the largest absolute decrease at Low (674 to 446 FPS, a 34% reduction) and the smallest at Ultra (325 to 215 FPS, a 34% reduction). The Medium setting's minimum of 315 FPS at 1440p is significant, as it indicates the combo can maintain 300+ FPS even in heavy load scenarios at this resolution.

At 3840x2160, the measured values are: Low 249, Medium 207 (minimum 176, maximum 238), High 155, and Ultra 120. The 4K Low result of 249 FPS is impressive for a game like CS2, showing the RTX 4080's raw power can push high frame rates even at 4K when graphical settings are reduced. The Medium setting's minimum of 176 FPS ensures smooth 144 Hz operation, while Ultra at 120 FPS sits right at the 120 Hz threshold — adequate for casual play but not ideal for competitive scenarios.

The complete data set shows a consistent pattern: each resolution step down (from 4K to 1440p to 1080p) yields roughly a 1.8x increase in FPS at the same settings. For example, 4K Low (249 FPS) to 1440p Low (446 FPS) to 1080p Low (674 FPS) shows this scaling clearly. This linear relationship indicates the combination is neither severely CPU-bound (which would flatten the scaling at higher resolutions) nor GPU-bound (which would show diminishing returns at lower resolutions), but rather transitions smoothly between the two components' capabilities.
