Counter-Strike 2

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 5090 D presents a striking imbalance in Counter-Strike 2. The data shows a CPU released in 2020 with a 2.90 GHz base clock and a 4.30 GHz boost clock, working alongside a flagship GPU that boasts a 2017 MHz base and 2407 MHz boost. This pairing produces a predictable bottleneck pattern. At 1080p with Low settings, the combination achieves 508 FPS average. Moving to 1440p Low drops this to 443 FPS, a 12.8% reduction. At 4K Low, the average falls to 301 FPS, which is a 40.7% reduction from the 1080p Low figure. The scaling from 1440p to 4K is particularly steep, suggesting that while the CPU can still feed frames at lower resolutions, the GPU's workload at 4K begins to dominate. However, the fact that 4K High still produces 187 FPS indicates the GPU is far from saturated; the limiting factor is the CPU's single-thread performance, which is evidenced by its 3dmark_single_thread score of 688 and passmark_single_thread score of 2541. The data suggests that at 1080p, the i5-10400F is the primary constraint, as the FPS difference between Low (508) and High (428) is only 15.7%, a relatively small gap for a GPU of this caliber.

Resolution Scaling

The resolution scaling data reveals a classic CPU-bound scenario at lower resolutions that gradually transitions toward a more balanced workload at 4K. At 1080p, the spread between the lowest and highest settings is 118 FPS (508 Low to 390 Ultra), indicating that the CPU is holding the GPU back from its full potential. When the resolution increases to 1440p, the spread narrows slightly to 183 FPS (443 Low to 260 Ultra), but the absolute FPS values remain high. The most telling transition occurs at 4K, where the spread widens dramatically to 156 FPS (301 Low to 145 Ultra), but the average FPS drops significantly. The 4K Medium setting shows a min FPS of 213 and max of 288, which represents a 75 FPS variance, suggesting that while the GPU is more involved, the CPU still causes occasional frame hitches. The data indicates that the i5-10400F, with its 6 cores and 12 threads, reaches its practical limit around 300-500 FPS depending on the settings, and the RTX 5090 D is never fully utilized until 4K Ultra, where the GPU's 32 GB of GDDR7 memory and 1.79 TB/s bandwidth finally become relevant factors. The scaling from 1080p to 4K at High settings shows a 56.3% drop (428 to 187 FPS), which is substantial but not as severe as one might expect from a 4x pixel count increase, reinforcing that the CPU is the dominant limiting component across most of the tested configurations.

GPU Role

The RTX 5090 D plays a supporting role in this configuration, as the benchmark results demonstrate. The GPU's 32 GB of GDDR7 memory on a 512-bit bus provides 1.79 TB/s of bandwidth, which is far beyond what Counter-Strike 2 requires, even at 4K Ultra. The GPU's 104.8 TFLOPS of FP32 performance and 21760 shading units are largely underutilized in this game. The data shows that at 4K Ultra, the average FPS of 145 is the lowest recorded, but this is still a playable frame rate. The GPU's boost clock of 2407 MHz, combined with its 92,200 million transistors on a 5 nm process, ensures that it is never the bottleneck in this pairing. The passmark_g3d score of 44065 places it in the 92nd percentile of all GPUs, yet in Counter-Strike 2, the i5-10400F's 3dmark_2_threads score of 1350 and 3dmark_4_threads score of 2560 suggest that the game's engine is not scaling well with the GPU's massive parallelism. The GPU's VRAM capacity is irrelevant here, as Counter-Strike 2 is not a VRAM-intensive title; the 32 GB allocation dwarfs any possible requirement. The nearest rival data for the GPU shows a deltaPct of 1.1% against the AMD Radeon RX 6650M XT, which is a mobile GPU, highlighting that the RTX 5090 D's performance in synthetic benchmarks does not translate to a proportional advantage in this CPU-limited scenario. The GPU's role is to provide headroom; at 1080p Low, the FPS of 508 is likely close to the CPU's maximum frame output, not the GPU's.

How This Combo Ranks

This specific combination ranks 181 out of 2870 tested combos in Counter-Strike 2, placing it in the top 6.3% of all tested systems. This ranking is notably high, but it is a reflection of the GPU's raw power rather than the CPU's capability. The i5-10400F's percentileVsAllCpus is 68, indicating it performs better than 68% of all CPUs in the database, but its nearest rivals include the Intel Xeon 6756E (0.2% delta) and AMD EPYC 7552 (0.5% delta), which are server-class processors. This suggests that the i5-10400F is a mid-range desktop chip that happens to be paired with a top-tier GPU. The combo rank of 181 is impressive, but the data implies that a more modern CPU would push this combination much higher. The GPU's percentileVsAllGpus is 92, meaning it outperforms 92% of all GPUs, yet the overall combo rank is dragged down by the CPU's limitations. In practical terms, this combo ranks higher than 94% of all tested systems, but the FPS numbers in Counter-Strike 2 are not as high as the GPU's synthetic scores would suggest. The 3dmark_16_threads score of 4748 for the CPU indicates that multi-threaded workloads are handled adequately, but the game's reliance on single-thread performance, as shown by the 3dmark_single_thread score of 688, is where the bottleneck lies.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across three resolutions and four settings levels. At 1080p, the Low setting yields 508 FPS average, while Medium produces 476 FPS with a min of 405 and max of 548. High settings reduce the average to 428 FPS, and Ultra drops it to 390 FPS. The variance between Low and Ultra at 1080p is 118 FPS, which is relatively modest, confirming the CPU limit. At 1440p, the Low setting achieves 443 FPS, Medium 415 FPS (min 353, max 477), High 334 FPS, and Ultra 260 FPS. The drop from Low to Ultra at 1440p is 183 FPS, showing a wider spread as the GPU begins to matter more. At 4K, the numbers are 301 FPS for Low, 250 FPS for Medium (min 213, max 288), 187 FPS for High, and 145 FPS for Ultra. The 4K Ultra figure of 145 FPS is the lowest recorded, but it is still well above the 60 FPS threshold for smooth gameplay. The data reveals that the Medium settings at each resolution provide the most stable frame times, as evidenced by the min/max values being closest together. For example, at 1080p Medium, the min of 405 and max of 548 show a 143 FPS range, which is tighter than the estimated range at other settings. The 4K Medium data shows a 75 FPS range (213 to 288), indicating that this setting offers the best balance of visual fidelity and frame time consistency.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and refresh rate. For 1080p displays with 240 Hz or 360 Hz refresh rates, the Low setting at 508 FPS is the only option that can fully saturate such high refresh rates. However, the Medium setting at 476 FPS still exceeds 360 Hz and provides better visuals with a min FPS of 405, ensuring that even the slowest frames remain above 360 Hz. For 1440p, the Low setting at 443 FPS is sufficient for 360 Hz monitors, but the Medium setting at 415 FPS with a min of 353 FPS is a safer choice for maintaining a stable frame rate above 360 Hz, provided the monitor supports it. For 1440p at 240 Hz, the High setting at 334 FPS is more than adequate and offers a significant visual upgrade over Medium. For 4K gaming, the data suggests that the High setting at 187 FPS is the best choice for 144 Hz displays, as it provides a high average with the GPU taking on more work. The 4K Medium setting at 250 FPS is better suited for 240 Hz displays, but its min of 213 FPS means frame drops could dip below 240 Hz. The 4K Ultra setting at 145 FPS is viable for 120 Hz displays but is not recommended for competitive play due to its lower average. The data indicates that the Medium preset across all resolutions offers the most consistent frame pacing, making it the safest recommendation for a balance of performance and stability.

CPU Role

The Intel Core i5-10400F plays a critical role in determining the overall performance of this combo in Counter-Strike 2. With 6 cores and 12 threads, the CPU has a base clock of 2.90 GHz and a boost clock of 4.30 GHz, which are modest figures compared to modern processors. The 3dmark_single_thread score of 688 and the 3dmark_2_threads score of 1350 highlight the CPU's single-thread and dual-thread capabilities, which are crucial for a game engine that is not heavily multi-threaded. The data shows that the CPU's performance ceiling is reached at around 508 FPS, as evidenced by the 1080p Low result. The CPU's 12 MB of shared L3 cache and dual-channel DDR4 memory support (42.7 GB/s bandwidth) are sufficient for this game, but they do not provide the headroom that a newer architecture would offer. The passmark_multithread score of 12115 and cinebench_r23_multicore score of 10283 indicate that the CPU handles multi-threaded workloads adequately, but these are not the primary factors in Counter-Strike 2. The 3dmark_16_threads score of 4748 suggests that the CPU's multi-threading is efficient, but the game's reliance on single-thread performance means that the 3dmark_single_thread score of 688 is more indicative of real-world results. The CPU's 14 nm process node and 65 W TDP are outdated compared to the GPU's 5 nm process, but the data shows that the CPU is still capable of delivering high frame rates, albeit not as high as a more modern processor would. The nearest rival data for the CPU, with deltas of only 0.2% to 0.6% against server-class and mobile processors, further confirms that the i5-10400F is a mid-range part that limits the RTX 5090 D's potential in this CPU-bound title.
