# Pc Building Simulator — Intel Core i7-12700K + NVIDIA GeForce RTX 4080

The Intel Core i7-12700K paired with the NVIDIA GeForce RTX 4080 delivers a benchmark profile that is heavily asymmetric across resolutions, with the simulation's engine scaling in a way that points to a clear CPU-limited ceiling at lower settings. At 1080p Low, the combo reaches 403 FPS average, while at 4K Ultra it drops to 74 FPS, a span that reveals more about the game's thread utilization and the CPU's 12-core/20-thread layout than about raw GPU throughput. The data set includes twelve measured FPS points across three resolutions and four quality presets, providing a complete picture for a builder-focused simulation that rewards high refresh rates.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but uneven across presets, indicating that the limiting component shifts depending on the settings level. At Low settings, the average FPS falls from 403 at 1080p to 297 at 1440p (a 26% reduction) and then to 155 at 4K (a 48% reduction from 1440p). This progression shows that even at Low, the RTX 4080's 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are still being exercised, but the 1080p Low result of 403 FPS suggests the CPU—with its 5.00 GHz boost clock and 12 cores—is already near its practical limit for this game's simulation logic.

At Medium settings, the scaling is more moderate: 333 FPS at 1080p, 210 at 1440p, and 110 at 4K. The 1440p Medium figure of 210 FPS with a 179 FPS minimum and 242 FPS maximum shows a tight frame delivery window, which points to consistent frame pacing rather than GPU-bound stutter. The 4K Medium result of 110 FPS, with a 93 FPS minimum, still clears 90 FPS but begins to show the GPU's workload increasing.

High settings produce 235 FPS at 1080p, 148 at 1440p, and 78 at 4K. The 1080p High figure is only 42% lower than 1080p Low, while 4K High is 50% lower than 4K Low. This suggests that at 4K, the GPU's shading units (9,728) and texture units (304) are becoming the primary constraint, whereas at 1080p, the CPU's single-thread performance (3DMark single-thread score of 1,043) plays a larger role.

Ultra settings show the most dramatic scaling: 224 FPS at 1080p, 141 at 1440p, and 74 at 4K. The 4K Ultra figure is the lowest in the entire data set and represents a 67% drop from the 1080p Ultra result. The gap between 1080p Ultra (224 FPS) and 1080p High (235 FPS) is just 11 FPS, but the gap between 4K Ultra (74 FPS) and 4K High (78 FPS) is only 4 FPS, indicating that resolution is the dominant factor at 4K, not the additional Ultra preset overhead.

The limiting component analysis: at 1080p across all settings, the CPU's 25 MB shared L3 cache and 20 threads are likely the bottleneck, as evidenced by the relatively small FPS differences between Low (403) and Ultra (224) — a 44% spread. At 4K, the GPU's 48.74 TFLOPS FP32 throughput becomes the constraint, with the spread from Low (155) to Ultra (74) being 52%. The 1440p results sit in a transitional zone where neither component is fully saturated, with all four presets staying above 140 FPS.

FAQ

Q: What is the highest average FPS achieved by this combo?

A: The highest recorded average is 403 FPS at 1920x1080 with Low settings. The lowest average is 74 FPS at 3840x2160 with Ultra settings.

Q: How does the RTX 4080 compare to its nearest GPU rival in this context?

A: The RTX 4080's average benchmark score is 54,247, which is 0.1% ahead of the RTX 4080 SUPER (54,209) and 1.1% ahead of the AMD Radeon Pro W5700X (54,828). The GPU sits at the 86th percentile of all GPUs.

Q: What is the CPU's multi-threaded capability relative to its rivals?

A: The i7-12700K has an average benchmark score of 35,287, which is 0.1% behind the Intel Core i5-13600T (35,305) and 0.2% behind the i7-12700KF (35,365). Its Cinebench R23 multi-core score is 19,784, placing it at the 84th percentile of all CPUs.

Q: Does the game show better frame consistency at higher resolutions?

A: The data shows the opposite. The only min/max FPS values recorded are at Medium settings: at 4K, the range is 93–126 FPS (average 110), at 1440p it is 179–242 FPS (average 210), and at 1080p it is 283–383 FPS (average 333). The relative spread widens as resolution increases, from 30% at 1080p to 30% at 4K, but the absolute variance grows from 100 FPS to 33 FPS.

Q: How does this combo rank in this specific game?

A: The combo ranks 244th out of 3,723 tested combinations in Pc Building Simulator, placing it in the top 6.6% of all tested system pairings.

Q: What is the GPU's memory configuration and how might it affect 4K performance?

A: The RTX 4080 has 16 GB of GDDR6X memory on a 256-bit bus, delivering 716.8 GB/s bandwidth. The 4K Ultra result of 74 FPS suggests that this bandwidth is sufficient for the game's asset streaming, but the 112 ROPs may limit pixel fill at 4K.

Settings Recommendations

The measured data indicates that Medium settings offer the best balance of performance and visual fidelity for this combo, but the optimal choice depends on the target resolution. At 1080p, Medium delivers 333 FPS average with a 283 FPS minimum, which is 47% higher than High (235 FPS) and only 17% lower than Low (403 FPS). The 333 FPS figure far exceeds any display refresh rate, so the extra frames from Low settings are wasted, while High and Ultra provide minimal visual gains for a 30% FPS penalty.

At 1440p, Medium again stands out with 210 FPS average and a 179 FPS minimum. This is 42% higher than High (148 FPS) and 49% higher than Ultra (141 FPS), while Low reaches 297 FPS. For a 1440p 165 Hz display, Medium's 179 FPS minimum clears the refresh threshold, making it the only preset that guarantees a frame rate above 165 FPS throughout the measured window. High and Ultra both fall below 150 FPS average, which may still be acceptable for 144 Hz panels but leaves less headroom.

At 4K, the recommendation shifts. Medium produces 110 FPS average with a 93 FPS minimum, which is the highest preset that maintains a 90+ FPS minimum. High (78 FPS) and Ultra (74 FPS) are both below 80 FPS, while Low (155 FPS) sacrifices visual quality for a 41% FPS gain. For a 4K 120 Hz display, Medium is the only preset that stays above 90 FPS at the minimum, making it the clear choice. For 4K 60 Hz displays, High at 78 FPS offers better image quality with no perceptible difference in smoothness.

The Ultra preset is difficult to recommend at any resolution. At 1080p it delivers 224 FPS (only 3% lower than High), at 1440p it drops to 141 FPS (5% lower than High), and at 4K it reaches 74 FPS (5% lower than High). The performance cost of Ultra over High is consistently small (4–7 FPS), but the visual return is also minimal for a simulation game focused on menus and build interfaces rather than fast-paced rendering.

Measured FPS Breakdown

At 1920x1080, the full range of settings produces: Low at 403 FPS average, Medium at 333 FPS average with a 283 FPS minimum and 383 FPS maximum, High at 235 FPS average, and Ultra at 224 FPS average. The spread from Low to Ultra is 179 FPS, representing a 44% reduction. The Medium preset shows a 100 FPS range between minimum and maximum, which is the largest absolute variance recorded in the data set.

At 2560x1440, the results are: Low at 297 FPS average, Medium at 210 FPS average with a 179 FPS minimum and 242 FPS maximum, High at 148 FPS average, and Ultra at 141 FPS average. The reduction from 1080p to 1440p is 26% for Low, 37% for Medium, 37% for High, and 37% for Ultra. The Medium preset's 63 FPS range (179–242) is smaller in absolute terms than at 1080p but similar in relative terms (30%).

At 3840x2160, the results are: Low at 155 FPS average, Medium at 110 FPS average with a 93 FPS minimum and 126 FPS maximum, High at 78 FPS average, and Ultra at 74 FPS average. The reduction from 1440p to 4K is 48% for Low, 48% for Medium, 47% for High, and 48% for Ultra. This consistency across presets—all around 48%—strongly indicates that the GPU's pixel throughput is the limiting factor at 4K, regardless of quality settings.

The Medium preset is the only one with min/max data at all three resolutions, providing insight into frame pacing. The 4K Medium range of 93–126 FPS (33 FPS spread) is the tightest in absolute terms, while 1080p Medium's 283–383 FPS (100 FPS spread) is the widest. This suggests that at higher resolutions, the GPU's consistent frame times smooth out CPU-induced variance.

GPU Role

The RTX 4080's role in this game becomes more pronounced as resolution increases. With 16 GB of GDDR6X memory on a 256-bit bus and a bandwidth of 716.8 GB/s, the card has ample memory capacity for Pc Building Simulator's asset loading, but the 4K results show that raw compute throughput (48.74 TFLOPS FP32) is the primary constraint at that resolution. The card's boost clock of 2505 MHz and base clock of 2205 MHz operate within a 12% range, and the 4K FPS scaling from Low to Ultra (155 to 74) reflects the GPU's 112 ROPs handling pixel fill rates of 280.6 GPixel/s.

The GPU's benchmark scores reinforce its position. Its PassMark G3D score of 34,457 and 3DMark Steel Nomad DX12 score of 6,567 place it at the 86th percentile of all GPUs. Its nearest rival, the RTX 4080 SUPER, averages 54,209, a 0.1% difference, which explains why the 4080's 4K performance would be nearly indistinguishable from its successor. The AMD Radeon Pro W5700X (54,828) is 1.1% ahead, and the RX 6750 GRE 12 GB (55,698) is 2.6% ahead, but these are average benchmark scores, not game-specific results.

At 1080p, the GPU's role is diminished. The 403 FPS Low result is far beyond what the RTX 4080's 9,728 shading units need to saturate; instead, the 12-core CPU becomes the bottleneck. The GPU's 16 GB memory capacity is never stressed at 1080p, but at 4K Ultra, the combination of high-resolution textures and simulation state may approach the 16 GB limit, though the 74 FPS result suggests the card is compute-bound rather than memory-bound.

CPU Role

The Intel Core i7-12700K is the limiting factor at low resolutions and settings. Its 12 cores and 20 threads (Alder Lake architecture) provide strong multi-threaded performance, evidenced by a Cinebench R23 multi-core score of 19,784 and a PassMark multi-thread score of 34,404. However, its single-thread performance (3DMark single-thread score of 1,043, Geekbench single-core of 2,308) is what matters for a simulation game that may not scale perfectly across all 20 threads.

The 1080p results demonstrate this CPU ceiling. The difference between Low (403 FPS) and Ultra (224 FPS) is 179 FPS, but the difference between High (235 FPS) and Ultra (224 FPS) is just 11 FPS. This suggests that the game's rendering workload at 1080p is small enough that the CPU's 5.00 GHz boost clock determines the upper bound, and the GPU easily keeps pace. The CPU's 25 MB shared L3 cache and 80 KB L1 per core help with the game's simulation loops, which may involve frequent state checks for PC components.

The CPU's benchmark rivals show how close the field is. The i7-12700K's average score of 35,287 is 0.1% behind the i5-13600T (35,305) and 0.2% behind the i7-12700KF (35,365). This means the 12700K is effectively tied with its closest competitors, and any game-specific differences would come from the CPU's 10 nm process and 125 W TDP characteristics rather than raw compute. The CPU's 84th percentile ranking among all CPUs confirms that it is a high-tier part, but not the absolute top.

At 4K, the CPU's role diminishes. The 4K Low result of 155 FPS is still high enough that the CPU's 20 threads must be feeding the GPU at a rate that exceeds most games' requirements, but the 4K Ultra result of 74 FPS is clearly GPU-limited. The 4K Medium range of 93–126 FPS shows that the CPU can maintain a minimum of 93 FPS even at this resolution, meaning the CPU is not the cause of any frame drops below that threshold.

How This Combo Ranks

In Pc Building Simulator specifically, this combo ranks 244th out of 3,723 tested combinations, placing it in the top 6.6% of all system pairings. This rank is based on measured FPS data, not synthetic benchmarks, and reflects the game's particular sensitivity to CPU single-thread performance at lower resolutions and GPU throughput at higher ones.

The rank of 244 out of 3,723 is notable because the i7-12700K (84th percentile CPU) and RTX 4080 (86th percentile GPU) are both strong parts individually, yet the combo does not crack the top 200. This suggests that Pc Building Simulator rewards combinations with even higher single-thread CPU scores or more GPU memory bandwidth. The game's simulation nature may not fully utilize the 12700K's 20 threads, making its multi-threaded strength (Cinebench R23 multi-core of 19,784) less impactful than its single-core score (1,850.5 in Cinebench R23).

The 3,723 total combos include a wide range of hardware, and the 244th rank means this system outperforms 93.4% of tested configurations. The nearest CPU rivals in the benchmark database—the i5-13600T and i7-12700KF—have nearly identical average scores (within 0.2%), so the rank would likely shift by only a few positions if the CPU were swapped for one of those parts. Similarly, the GPU's nearest rival, the RTX 4080 SUPER, is only 0.1% ahead in average score, so the combo's rank is robust to minor component variations.

For a game that is about building PCs, the irony is that this high-end combo delivers excellent but not top-tier results: it easily handles 1440p Ultra at 141 FPS and 4K Medium at 110 FPS, but the 4K Ultra figure of 74 FPS is the only data point that falls below 90 FPS. The rank of 244 suggests that higher-ranked combos likely include newer CPUs with faster single-thread performance or GPUs with more ROPs, but within the measured data, this system offers a balanced experience across all resolutions and settings.
