To The Core

To The Core is an idle game that, on the surface, presents a simple loop, but the benchmark data for the Intel Core i5-13400F and NVIDIA GeForce RTX 3080 combination reveals a performance profile that scales with resolution in a way that defies the typical GPU-bound expectations. The measured FPS at 4K Ultra is 94.3, which is a significant drop from the 304 FPS seen at 1080p High, indicating that the rendering load is primarily on the graphics card, yet the sheer headroom at lower resolutions suggests the CPU is far from a bottleneck. This analysis will break down the measured data to understand where the limiting component lies and what the experience implies for a system built around this mid-range 13th Gen processor and the high-end Ampere GPU.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 shows a pronounced decline in frame rates, which is the expected behavior for a GPU-intensive workload. At High settings, the average FPS drops from 304 at 1080p to 201.6 at 1440p, and finally to 116.8 at 4K. This represents a 61.6% reduction in performance from 1080p to 4K, which is a substantial hit that clearly points to the RTX 3080 being the primary driver of performance at higher pixel counts. The data suggests that the 10 GB of GDDR6X memory and the 760.3 GB/s bandwidth are being taxed heavily by the 4K resolution, as the frame rate nearly halves compared to the 1080p result.

However, the scaling pattern offers a more nuanced story. When moving from Low settings to Ultra at 4K, the average FPS falls from 156.8 to 94.3, a 39.9% drop. This is a smaller relative decrease than the resolution scaling, which indicates that while the GPU is working harder at higher settings, the biggest performance cost comes from the sheer number of pixels. The fact that 1080p Low yields 415.8 FPS, a figure that exceeds the refresh rate of most monitors, suggests that the Core i5-13400F has ample headroom to feed the GPU at lower resolutions. The limiting component is clearly the GPU, as the CPU's role becomes less significant as the resolution increases and the frame rate drops.

How This Combo Ranks

The combo rank of 538 out of 1756 tested combinations places this system in the 69.4th percentile of all tested hardware pairings. This is a strong result, indicating that this pairing of the i5-13400F and RTX 3080 is well-balanced for this game. The rank is influenced by the fact that the CPU, while not top-tier, offers a single-thread score of 960 in 3DMark, which is crucial for an idle game that may rely heavily on a single-threaded game loop. The GPU's percentile rank of 80 versus all GPUs, and the CPU's percentile of 82 versus all CPUs, are closely aligned, which explains why this combo performs so well relative to other pairings.

The nearest rivals for the CPU, such as the Intel Core i7-13620H, have an average score of 25201, a mere 0.1% delta from the i5-13400F's average score of 25236. This indicates that the 13400F is performing at the upper edge of its class, and its 10 cores and 16 threads are more than sufficient for the game's demands. The GPU's nearest rival, the AMD Radeon Pro Duo, has an average score of 35860, which is a 0.2% delta from the RTX 3080's 35787. This suggests that the 3080 is not being held back by the CPU in this specific title, as the combo rank is high, but it also implies that a more powerful CPU might not yield significantly higher frame rates given the GPU's performance ceiling in this particular game.

Settings Recommendations

The measured data clearly indicates that the High preset offers the best balance of visual fidelity and performance for this combination. At 4K High, the system delivers 116.8 FPS, which is comfortably above the 60 FPS threshold for a smooth experience. At 1440p High, the 201.6 FPS average is exceptional, providing a high-refresh-rate experience without any compromise. The Low preset at 4K yields 156.8 FPS, but this comes at a significant visual cost, and the 39.9% performance gain over High is not worth the graphical downgrade for most users.

For those seeking the absolute maximum visual quality, the Ultra preset at 1440p delivers 165.8 FPS, which is still very playable and only a 17.7% drop from High. However, at 4K Ultra, the frame rate falls to 94.3 FPS, which is still playable but may dip below the refresh rate of some high-end monitors. The data suggests that Medium is a fallback option, but High is the sweet spot. The difference between High and Medium at 4K is 14.6% (116.8 vs 136.7 FPS), and given that High is the middle ground, it is recommended as the default setting for this hardware pairing.

Measured FPS Breakdown

The FPS measurements paint a clear picture of the system's capabilities across all resolutions and settings. At 1920x1080, the system is exceptionally fast, with an average of 415.8 FPS on Low, 348.2 on Medium, 304 on High, and 242.7 on Ultra. The gap between Low and Ultra is 41.6%, which shows that even at the lowest resolution, the GPU is still the primary bottleneck, as the CPU can push frame rates well beyond 400 FPS.

Moving to 2560x1440, the frame rates remain high but show a more pronounced drop. The Low setting averages 281.1 FPS, Medium drops to 232.5, High to 201.6, and Ultra to 165.8. The scaling from 1080p to 1440p at High settings is a 33.7% reduction, which is a significant jump. At 3840x2160, the performance becomes more demanding, with Low averaging 156.8 FPS, Medium 136.7, High 116.8, and Ultra 94.3. The difference between High and Ultra at 4K is 19.3%, which is more pronounced than at 1080p, where the gap is 19.9%. This indicates that the GPU is struggling to maintain high frame rates at 4K Ultra, but it is still capable of delivering a playable experience.

CPU Role

The Intel Core i5-13400F is a 10-core, 16-thread processor based on the Raptor Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. The benchmark data indicates that this CPU is more than capable of handling the game's logic, as its 3DMark single-thread score of 960 is respectable, and its Cinebench R23 multicore score of 21279 shows strong multi-threaded performance. For an idle game like To The Core, the game loop is often single-threaded, and the 13400F's single-thread performance is robust enough to avoid becoming a bottleneck, as evidenced by the high frame rates at 1080p.

The CPU's 20 MB of shared L3 cache is also a factor, as it provides a large pool of fast memory for the game's data. The fact that the combo ranks at 538 out of 1756, with a percentile of 82 for the CPU, suggests that the 13400F is well-suited for this game. The nearest rivals, such as the AMD Ryzen 5 5600X3D, have an average score of 25365, a -0.5% delta, which shows that the 13400F is on par with other mid-range options. The CPU is not the limiting component in this system, as the data shows that the GPU is the primary driver of frame rates, especially at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 3080 is a high-end graphics card based on the Ampere architecture, with 8704 shading units and 68 RT cores. It features 10 GB of GDDR6X memory on a 320-bit bus, providing 760.3 GB/s of bandwidth. The benchmark results show that this GPU is the dominant factor in this system's performance. At 4K Ultra, the card delivers 94.3 FPS, which is a 60.1% drop from the 242.7 FPS at 1080p Ultra. This scaling is a clear indication that the GPU's compute and memory bandwidth are being fully utilized at 4K.

The GPU's 3DMark Steel Nomad score of 4407 and its Passmark G3D score of 25086 place it in the 80th percentile of all GPUs. The RTX 3080's memory clocks are listed at 1188 MHz, with an effective speed of 19 Gbps, which is crucial for handling the high-resolution textures and effects in the game. The data suggests that the 10 GB VRAM is sufficient for this title, as the frame rates remain high even at 4K. The GPU's nearest rival, the AMD Radeon 880M, has a 0.4% delta in average score, which is negligible, but the RTX 3080's raw power is clearly visible in the measured FPS, as it is the sole determinant of performance across all settings and resolutions.
