Pc Building Simulator

Pc Building Simulator is a simulation title that scales unusually well with hardware, and the Intel Core Ultra 5 245 + NVIDIA GeForce RTX 5080 combo demonstrates this clearly. The data shows a configuration that is heavily GPU-limited at higher resolutions, yet has enough CPU headroom to deliver extreme frame rates at 1080p.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic GPU-bound scenario, but with an interesting twist at the top end. At 1080p with High settings, the combo produces 244 FPS. Moving to 1440p drops that to 154 FPS, a 37% reduction. At 4K, the average falls to 80 FPS, which is a 67% drop from the 1080p figure. This steep curve indicates that the RTX 5080 is the primary limiter as resolution increases, with the CPU providing ample headroom at lower resolutions.

The Low settings preset shows an even more dramatic scaling pattern. At 1080p, the combo hits 462 FPS, which is a massive 88% higher than the High preset at the same resolution. At 1440p, Low still delivers 307 FPS, and even at 4K it maintains 161 FPS. The gap between Low and High settings widens as resolution drops, suggesting that the game's lower presets remove GPU bottlenecks that would otherwise cap performance.

The Medium preset sits between these extremes. At 4K, it achieves 114 FPS with a minimum of 97 FPS and a maximum of 131 FPS. At 1440p, Medium jumps to 218 FPS, and at 1080p it reaches 345 FPS. The scaling from 4K to 1440p for Medium is a 91% improvement, while going from 1440p to 1080p yields another 58% gain. This non-linear scaling is typical of a game where pixel throughput becomes the dominant cost at higher resolutions.

Ultra settings show the most conservative numbers. The 4K Ultra average is 77 FPS, barely above the High preset's 80 FPS. At 1440p, Ultra hits 146 FPS, and at 1080p it reaches 232 FPS. The tight gap between High and Ultra at 4K (77 vs 80 FPS) suggests that the Ultra preset adds effects that are mostly resolution-independent, meaning the GPU is already saturated at 4K regardless of the extra visual fidelity.

The limiting component analysis is straightforward: the RTX 5080 is the bottleneck at 1440p and 4K, while the Core Ultra 5 245 becomes more relevant at 1080p. The 462 FPS result at 1080p Low indicates that the CPU can feed the GPU far beyond what most displays can show, and the gap between 1080p and 1440p results confirms that the GPU's rendering throughput is the constraining factor as pixels increase.

GPU Role

The RTX 5080 brings 16 GB of GDDR7 memory on a 256-bit bus, providing 960.0 GB/s of bandwidth. This memory configuration is directly relevant to Pc Building Simulator's results because the game's asset-heavy environments and UI elements benefit from high bandwidth, especially at 4K where the 80 FPS High average stays playable. The GPU's boost clock of 2617 MHz with a base of 2295 MHz helps sustain these frame rates, and the 10752 shading units provide the raw compute needed for the simulation's rendering workloads.

The GPU's memory capacity of 16 GB is ample for this title, as evidenced by the minimal performance drop from High to Ultra at 4K (80 to 77 FPS). This small delta suggests that the Ultra preset's additional memory usage does not exceed the available VRAM, keeping the GPU from resorting to slower memory paging. The 960.0 GB/s bandwidth is a significant factor in the 4K Medium result of 114 FPS, where the game's medium textures still require substantial data throughput.

The RTX 5080's position in the broader GPU landscape is solid. It sits in the 87th percentile of all GPUs, with an average benchmark score of 56083. Its nearest rivals include the AMD Radeon 8060S at 55757 (0.6% slower), the AMD Radeon RX 6750 GRE 12 GB at 55698 (0.7% slower), and the AMD Radeon Pro W5700X at 54828 (2.3% slower). The AMD Radeon RX 9070 GRE is 2.2% faster at 57367. These small deltas indicate that the RTX 5080 is competitive with top-tier alternatives, and in this game, those margins translate to single-digit FPS differences at most settings.

The GPU's 84 RT cores and 336 tensor cores are not heavily utilized in Pc Building Simulator, which is primarily a rasterization-heavy title. This explains why the Ultra preset only marginally outperforms High in terms of visual impact while costing similar frame rates. The GPU's 112 ROPs handle the final pixel output, and at 4K Ultra, the 77 FPS average aligns with what these ROPs can sustain given the game's draw calls.

How This Combo Ranks

This specific combination of the Intel Core Ultra 5 245 and NVIDIA GeForce RTX 5080 ranks 116th out of 3002 tested combos in Pc Building Simulator. That places it in the top 3.9% of all configurations tested, which is a strong showing for a mid-range CPU paired with a high-end GPU. The rank reflects the game's sensitivity to GPU performance, as the RTX 5080 carries most of the weight in this pairing.

The combo's position relative to other tested configurations makes sense given the CPU's benchmark profile. The Core Ultra 5 245 has an average benchmark score of 48995, placing it in the 90th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 7 PRO 5755G at 49196 (-0.4%), the AMD Ryzen 9 7900 at 49228 (-0.5%), the Intel Xeon Gold 5318H at 48698 (0.6%), and the Intel Core i5-14600K at 48618 (0.8%). These rivals are all within 1% of the Core Ultra 5 245's score, meaning that swapping to any of them would produce nearly identical frame rates in this game.

The 116th rank out of 3002 combos suggests that there are 115 configurations that perform better, likely featuring more powerful GPUs like the RTX 5090 or RX 9070 XT. However, the delta between this combo and those above it is probably small, given that the game's frame rates at 4K are already above 60 FPS on High settings. The rank also accounts for the CPU's 14 cores and 14 threads, which are sufficient for this simulation title's processing demands.

Settings Recommendations

Based on the measured FPS rows, the Medium preset offers the best balance of visual quality and performance for most users. At 4K, Medium delivers 114 FPS with a minimum of 97 FPS, which is well above the 60 FPS threshold for smooth gameplay. At 1440p, Medium hits 218 FPS, and at 1080p it reaches 345 FPS. The minimum frame rates of 97 FPS at 4K and 185 FPS at 1440p show that the Medium preset maintains consistent performance without severe dips.

For users with high refresh rate displays at 1440p, the High preset is the better choice. It produces 154 FPS at 1440p, which is still above most 144Hz monitors' refresh rates, while offering improved visual fidelity over Medium. At 1080p, High hits 244 FPS, which is excellent for 240Hz displays, though the Ultra preset at 232 FPS is nearly as fast and provides the best image quality.

The Ultra preset is only recommended for 1080p gaming, where it achieves 232 FPS. At 1440p, the 146 FPS average is still playable but represents a meaningful drop from High (154 FPS) for minimal visual gains. At 4K, the 77 FPS Ultra average is below the 80 FPS High average, making High the superior choice for 4K displays. The Low preset is not recommended for regular play, as the 462 FPS at 1080p exceeds display capabilities and the visual compromises are unnecessary given the High preset's strong performance.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. The Low preset averages 462 FPS, which is the fastest measured result in the entire dataset. Medium follows at 345 FPS with a minimum of 293 FPS and a maximum of 397 FPS. High hits 244 FPS, and Ultra trails at 232 FPS. The spread from Low to Ultra is 230 FPS, indicating that the game's settings have a substantial impact at this resolution.

At 2560x1440, the performance scales down proportionally. Low averages 307 FPS, Medium 218 FPS (minimum 185, maximum 250), High 154 FPS, and Ultra 146 FPS. The gap between High and Ultra narrows to just 8 FPS at this resolution, suggesting that the Ultra preset's extra effects are less demanding relative to the pixel count. The Medium preset's 218 FPS is particularly strong for 1440p high-refresh monitors.

At 3840x2160, the GPU takes center stage. Low averages 161 FPS, Medium 114 FPS (minimum 97, maximum 131), High 80 FPS, and Ultra 77 FPS. The difference between High and Ultra is only 3 FPS, making High the obvious choice for 4K. The Medium preset's 114 FPS is the standout result here, providing nearly 50% more performance than High while likely maintaining good visual quality.

The minimum and maximum frame rate data is only available for the Medium preset across all resolutions. At 1080p, the range is 293 to 397 FPS, a 104 FPS spread. At 1440p, it narrows to 185 to 250 FPS, a 65 FPS spread. At 4K, it tightens further to 97 to 131 FPS, a 34 FPS spread. This pattern indicates that frame time consistency improves as resolution increases, likely because the GPU's workload becomes more uniform at higher pixel counts.

CPU Role

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor based on the Arrow Lake architecture, built on a 3 nm process by TSMC. It has a base clock of 3.50 GHz and a boost clock of 5.10 GHz, with 24 MB of shared L3 cache. These specifications are more than adequate for Pc Building Simulator, which is not heavily multithreaded compared to other simulation titles.

The CPU's benchmark scores reinforce its capability. In Cinebench R23, it scores 32924 multicore and 4648 singlecore. The singlecore score is particularly relevant for this game, as Pc Building Simulator's simulation logic and UI rendering tend to favor single-thread performance. The Passmark single-thread score of 4394 and the Passmark physics score of 2569 indicate solid per-core performance.

The CPU's 65W TDP and 14 cores provide enough headroom for background tasks while gaming, but the data shows that the CPU is not the bottleneck in this pairing. At 1080p Low, the 462 FPS result demonstrates that the CPU can feed the GPU at extremely high frame rates. The fact that 1080p Ultra (232 FPS) is less than half of 1080p Low (462 FPS) confirms that the GPU is the limiting factor even at the lowest resolution.

The Core Ultra 5 245's position relative to its nearest rivals is tight. It trails the AMD Ryzen 7 PRO 5755G by 0.4% and the AMD Ryzen 9 7900 by 0.5%, while leading the Intel Xeon Gold 5318H by 0.6% and the Intel Core i5-14600K by 0.8%. In Pc Building Simulator, these differences would translate to less than 2% frame rate variation, meaning any of these CPUs would produce nearly identical results with the same GPU.

The CPU's 5.10 GHz boost clock is the key feature for this game. Single-threaded tasks, such as the game's component compatibility calculations and shop interface, benefit directly from high clock speeds. The 14 cores ensure that the game's background simulation threads, which handle things like PC building physics and component temperatures, run without competing with the main game thread for resources.
