To The Core

The Intel Core i7-13700K and NVIDIA GeForce RTX 4080 combination delivers exceptional performance in To The Core, an idle game that scales decisively with both the CPU's 16 cores and the GPU's massive rendering throughput. The measured data shows a system that is overkill for most display configurations, yet the scaling patterns reveal where each component takes charge. This analysis breaks down the benchmark results across resolutions and settings, placing the combo in context against the 3,725 tested combinations.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but linear, indicating a balanced system where neither component becomes a bottleneck at any tested resolution. At Low settings, the frame rate falls from 552 FPS at 1920x1080 to 212 FPS at 3840x2160—a 61.6% reduction. This is a classic sign of GPU-bound scaling: as pixel count quadruples, the rendering load increases proportionally, and the RTX 4080's 48.74 TFLOPS FP32 throughput and 716.8 GB/s memory bandwidth are the limiting factors.

The gap narrows slightly at higher presets. At Ultra settings, the drop from 326 FPS at 1080p to 125 FPS at 4K represents a 61.7% decrease, nearly identical to Low. This consistency suggests the game's rendering pipeline is uniformly GPU-intensive across quality levels, with no sudden CPU stalls or memory bandwidth cliffs. The 4K Ultra result of 125 FPS is still far above the 60 FPS threshold, confirming the RTX 4080 handles even the most demanding configuration with headroom.

Notably, the Medium preset at 4K shows a min FPS of 153 and max FPS of 207, with an average of 180 FPS. This 54 FPS spread indicates frame pacing variance that is absent in the other settings, where only averages were recorded. The 4K Low result of 212 FPS is 36.4% higher than 4K Medium, suggesting that the Low preset removes a significant amount of shading work, allowing the GPU to push closer to its raw fill rate limits.

The 1440p results sit in a sweet spot. At High settings, the average is 272 FPS, which is 42.9% higher than the 4K High result of 156 FPS. This scaling is exactly what one would expect from a GPU with a 256-bit memory bus and 112 ROPs—the pixel throughput is the primary constraint. The 1080p results, exceeding 400 FPS at most settings, are so high that they likely exceed the refresh rate of any consumer display, making the CPU's role nearly irrelevant at that resolution.

The data suggests the limiting component shifts from GPU to CPU only at 1080p Low, where 552 FPS approaches the practical ceiling for even a high-core-count processor. At 4K Ultra, the 125 FPS result shows the RTX 4080 operating at 78% of its 1080p Low throughput, which is a reasonable efficiency curve for a chip with 45,900 million transistors on a 5 nm process.

CPU Role

The Intel Core i7-13700K contributes significantly to this combo's performance, particularly in a genre like idle games where background simulation threads can multiply. With 16 cores, 24 threads, and a boost clock of 5.40 GHz, this processor provides ample parallel throughput for the game's logic, which runs concurrently with rendering. The 3.40 GHz base clock ensures consistent performance under sustained loads, while the 30 MB shared L3 cache reduces memory latency for frequently accessed game state.

Benchmark data shows the i7-13700K achieves a Passmark multithread score of 45,887 and a single-thread score of 4,333, placing it in the 89th percentile among all CPUs. Its nearest rival, the AMD Ryzen 9 5900, averages 46,971 points—a mere 0.2% difference, meaning the Intel chip is statistically equivalent in aggregate performance. However, the 3DMark results reveal its strength: 12,412 points at max threads and 1,136 points single-thread, which supports high frame rates in CPU-light scenes.

The CPU's role becomes apparent when examining the measured FPS at 1080p. At Low settings, the combo achieves 552 FPS, which is 36.4% higher than the 4K Low result of 212 FPS. This gap is almost entirely GPU-driven. But the fact that 1080p Low reaches 552 FPS without dropping below the average indicates the i7-13700K's 16 cores are not a constraint. The 3DMark 16-thread score of 10,717 suggests that even if the game spawns 16 simulation threads, the CPU can sustain the required instructions per second.

The CPU's cache hierarchy is also relevant. The 80 KB L1 per core and 2 MB L2 per core provide low-latency access to hot data, while the 30 MB shared L3 helps when multiple cores access the same game entities. This is particularly important for idle games, where many objects may share state. The 10 nm process node and 125 W TDP indicate the processor can maintain high clocks without thermal throttling, assuming adequate cooling.

At 4K, the CPU's influence diminishes. The 125 FPS Ultra result is 61.7% lower than 1080p Ultra, a proportion that matches the pixel count increase. This is the signature of a GPU bottleneck—the CPU is waiting on the GPU to finish rendering, not the other way around. The i7-13700K's 3DMark 2-thread score of 2,262 and 4-thread score of 4,469 suggest that even if the game uses only a few threads for rendering submission, the CPU can keep up with the RTX 4080's frame output.

The Geekbench multicore score of 19,429 further confirms the CPU's headroom. In practice, this means the i7-13700K is not the limiting factor in any of the 12 measured configurations. The CPU's 89th percentile ranking, combined with the GPU's 86th percentile, creates a balanced pairing where the GPU dictates performance at higher resolutions and the CPU ensures no frame drops at lower resolutions.

FAQ

Q: Why does 4K Ultra (125 FPS) perform worse than 1080p Low (552 FPS)?

A: The RTX 4080's rendering workload increases with pixel count and quality settings. At 4K Ultra, the GPU processes 8.3 million pixels with full effects, whereas 1080p Low reduces both resolution and shading complexity.

A: The RTX 4080 averages 54,247 points compared to the 4080 SUPER's 54,209, a 0.1% difference. This means the two cards perform identically in synthetic benchmarks, but the measured FPS in To The Core reflects the specific game's optimization, which may favor one over the other.

How This Combo Ranks

The Intel Core i7-13700K + NVIDIA GeForce RTX 4080 combo ranks 226th out of 3,725 tested combinations, placing it in the top 6.1% of all systems. This is a strong result for a pairing of a mid-high-range CPU with an upper-mid-range GPU. The 89th percentile CPU score and 86th percentile GPU score indicate that both components are above average, but the combo's rank suggests that some higher-tier CPUs or GPUs achieve better results in this specific game.

Examining the nearest rivals provides context. The CPU's closest competitor, the AMD Ryzen 9 5900, has an average score of 46,971 versus the i7-13700K's 46,881, a 0.2% deficit. This means the CPU is effectively tied with its rival, so any performance difference in the combo rank must come from the GPU. Similarly, the RTX 4080's nearest rival, the RTX 4080 SUPER, scores 54,209 versus 54,247, a 0.1% difference. These tiny deltas suggest that the combo's 226th rank is not due to a weak component but rather to the presence of many combos with higher-tier hardware.

The rank of 226 out of 3,725 is notable because it places the combo ahead of the vast majority of systems. For comparison, a combo in the top 10% would be ranked 372nd or better. This system exceeds that threshold by 146 positions. The data does not provide a list of combos ranked higher, but the percentile scores imply that systems with CPUs in the 90th+ percentile or GPUs in the 90th+ percentile likely occupy the top 200 positions.

In terms of game-specific performance, the measured FPS values are high across all settings. The lowest result, 125 FPS at 4K Ultra, is still 58% above the 60 FPS standard for smooth gameplay. The highest result, 552 FPS at 1080p Low, is so high that it would only be useful for competitive play on high-refresh monitors. This breadth of performance suggests the combo is versatile, capable of handling both maximum quality and maximum frame rate scenarios.

The combo's rank is also influenced by the game's genre. As an idle game, To The Core may place more emphasis on CPU simulation than GPU rendering, which would benefit the i7-13700K's 16 cores. However, the GPU still dominates the FPS scaling, as shown by the resolution analysis. This balance results in a combo that is neither CPU-bound nor GPU-bound at typical settings, which is an ideal characteristic for a benchmark database.

Measured FPS Breakdown

The measured FPS data covers 12 configurations: four settings (Low, Medium, High, Ultra) at three resolutions (1080p, 1440p, 4K). All results are averages, with only the Medium preset providing min and max FPS values.

At 1920x1080, the combo achieves its highest frame rates. Low settings produce 552 FPS average, which is the peak across all tests. Medium settings reduce this to 467 FPS, with a min of 397 FPS and max of 537 FPS. High settings yield 405 FPS, and Ultra drops to 326 FPS. The spread from Low to Ultra is 226 FPS, representing a 40.9% reduction in performance when moving from minimal to maximum quality.

At 2560x1440, the results show a predictable decline. Low settings average 371 FPS, Medium averages 314 FPS (min 267, max 361), High averages 272 FPS, and Ultra averages 219 FPS. The Low-to-Ultra spread is 152 FPS, a 41% reduction. Compared to 1080p, each setting is 32.8% to 33.1% lower, which closely matches the pixel count increase from 2.07 million to 3.69 million (a 78% increase, but with diminishing returns due to GPU architecture).

At 3840x2160, the frame rates remain high but show the GPU's limits. Low settings average 212 FPS, Medium averages 180 FPS (min 153, max 207), High averages 156 FPS, and Ultra averages 125 FPS. The Low-to-Ultra spread is 87 FPS, a 41% reduction, consistent with the other resolutions. The 4K results are 61.6% to 61.7% lower than their 1080p counterparts, which aligns with the 4x pixel count increase, confirming that the RTX 4080 scales in a linear fashion with resolution.

The Medium preset is the only one with min and max FPS data. At 1080p, the min of 397 FPS and max of 537 FPS produce a 140 FPS range, or 30% of the average. At 1440p, the range is 94 FPS (267 to 361), or 30% of the 314 FPS average. At 4K, the range is 54 FPS (153 to 207), or 30% of the 180 FPS average. This consistent 30% variance suggests that the game's frame time distribution is stable across resolutions, likely due to periodic CPU-side simulation spikes that cause brief frame drops.

The data shows that the RTX 4080's performance is highly predictable: each resolution step down (from 4K to 1440p) yields approximately 73% more FPS, and each step down (from 1440p to 1080p) yields approximately 50% more FPS. This is consistent with a GPU that is not bottlenecked by any other component in the system.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the user's display and performance goals. For a 60 Hz display, any configuration is sufficient, but the 4K Ultra preset at 125 FPS provides the best visual quality without sacrificing smoothness. For a 144 Hz display, 4K High at 156 FPS exceeds the refresh rate, offering a perfect balance of quality and speed. For a 240 Hz display, 1440p High at 272 FPS or 1080p Ultra at 326 FPS would be required to fully utilize the refresh rate.

The Medium preset offers the most consistent frame pacing, as evidenced by its min and max FPS data. At all three resolutions, the variance is exactly 30% of the average, which suggests the game's simulation updates occur at regular intervals. For users who prioritize frame time consistency over raw average FPS, Medium is the safest choice. At 4K Medium, the 180 FPS average with a 153 FPS minimum guarantees no visible stutter even during complex simulation updates.

For maximum visual fidelity, the Ultra preset at 4K yields 125 FPS, which is still 108% higher than the 60 FPS threshold. The drop from High to Ultra at 4K is 31 FPS (156 to 125), a 19.9% reduction. This is a significant cost in performance for the additional graphical effects, but the absolute frame rate remains high. At 1440p, Ultra delivers 219 FPS, which is 40.4% higher than 4K Ultra, making it the recommended choice for high-refresh monitors.

The Low preset provides the highest frame rates but sacrifices visual quality. At 1080p, 552 FPS is only useful for competitive gaming on 360 Hz or 500 Hz monitors, which are rare. At 4K, 212 FPS is still excellent, but the visual downgrade from Medium (180 FPS) is likely noticeable. The data suggests that Low is best suited for users who prioritize frame rate above all else, but the Medium preset offers a better balance.

Considering the game's idle genre, where players may leave the game running for extended periods, the Medium preset at 1440p (314 FPS) is the recommended default. It provides a 30% variance buffer (min 267 FPS) that handles any simulation spikes, while the 314 FPS average is high enough for any current display. For 4K users, Medium at 180 FPS is the best choice, as it maintains the same 30% variance with a minimum of 153 FPS, ensuring smooth gameplay without the 31 FPS penalty of Ultra.

The Ultra preset is only recommended for users with 4K 120 Hz displays who want the highest quality, as the 125 FPS average is just above the 120 Hz threshold. For 1440p 240 Hz displays, Ultra at 219 FPS is sufficient, but High at 272 FPS provides more headroom. Ultimately, the data shows that this combo is so powerful that the user can prioritize either quality or frame rate without compromising the other, making the choice a matter of personal preference rather than hardware limitation.
