# Pc Building Simulator — Intel Core Ultra 5 245 + NVIDIA GeForce RTX 5090

Pc Building Simulator, a 2019 simulation title, presents an unusual workload profile that combines light 3D rendering with heavy CPU-side logic simulation. The pairing of the Intel Core Ultra 5 245 with the NVIDIA GeForce RTX 5090 produces frame rates that range from 84 FPS at 4K Ultra to 462 FPS at 1080p Low, with the data revealing a complex interaction between resolution, settings, and the two primary components. The measured results indicate this combination ranks 44th out of 3002 tested configurations for this specific game, placing it in the top 1.5% of all tested combos, though the scaling behavior suggests the game's engine imposes significant constraints that neither component can fully overcome.

Resolution Scaling

The FPS progression across resolutions for this combo tells a clear story about where the bottleneck shifts. At 1080p Low, the system delivers 462 FPS; moving to 1440p Low drops that to 336 FPS (a 27.3% reduction), and 4K Low further reduces it to 176 FPS (a 47.6% reduction from 1440p). This steep scaling from 1080p to 4K at Low settings — a total drop of 61.9% — indicates that even at the lowest quality preset, the GPU is becoming progressively more limiting as pixel count increases, though the sheer magnitude of the frame rates suggests the CPU is still keeping pace admirably.

At High settings, the scaling pattern shifts notably. 1080p High produces 266 FPS, 1440p High drops to 168 FPS (a 36.8% reduction), and 4K High falls to 88 FPS (a 47.6% reduction from 1440p). The percentage drop from 1440p to 4K remains nearly identical between Low and High presets, which is a strong indicator that the game's rendering pipeline scales predictably with resolution regardless of quality level. However, the absolute numbers reveal that the RTX 5090's massive compute resources are being exercised more thoroughly at higher resolutions, with 4K High still maintaining a comfortable 88 FPS average.

The Medium settings rows provide the only complete min/max data in the measured set. At 1080p Medium, the average is 377 FPS with a minimum of 320 and maximum of 433. At 1440p Medium, the average falls to 238 FPS with a 202 minimum and 274 maximum. At 4K Medium, the average drops to 124 FPS with a 106 minimum and 143 maximum. The min-to-max spread of roughly 30% at each resolution suggests frame time variance that is consistent across resolutions, pointing to a game engine that has inherent pacing fluctuations rather than a hardware-specific stuttering issue.

Ultra settings show the most demanding scenario: 253 FPS at 1080p, 160 FPS at 1440p, and 84 FPS at 4K. The 4K Ultra result of 84 FPS represents the lowest measured average in the entire dataset, yet it remains above the 60 FPS threshold that many players consider the minimum for smooth gameplay. The scaling from 1080p Ultra to 4K Ultra is a 66.8% reduction, which is slightly steeper than the Low preset's 61.9% reduction, indicating that the combination of high resolution and high quality settings places additional strain on the GPU that goes beyond simple pixel count increases.

FAQ

Q: How does this combo perform at 4K compared to 1080p?

A: The average FPS at 4K Ultra is 84, which is 66.8% lower than the 253 FPS achieved at 1080p Ultra. Even at Low settings, 4K produces 176 FPS versus 462 FPS at 1080p, a 61.9% reduction. The game remains playable at 4K across all presets, but the frame rate penalty for resolution scaling is substantial.

Q: What is the best settings preset for smooth gameplay at 1440p?

A: At 1440p, the Medium preset delivers 238 FPS average with a 202 FPS minimum, which provides a comfortable margin above any display refresh rate up to 240Hz. High settings at 1440p produce 168 FPS, which still exceeds 144Hz displays. Ultra at 1440p yields 160 FPS, making all presets viable at this resolution.

Q: Does the RTX 5090's 32GB VRAM matter for this game?

A: The measured data does not indicate VRAM capacity as a limiting factor at any resolution or settings combination. The game's minimum FPS values at Medium settings (106 at 4K, 202 at 1440p, 320 at 1080p) do not suggest memory-related stuttering. The GPU's 32GB GDDR7 memory with 1.79 TB/s bandwidth appears more than sufficient for this title.

Q: How does this combo rank against other tested configurations?

A: This pairing ranks 44th out of 3002 tested combos for Pc Building Simulator, placing it in the top 1.5% of all tested systems. The CPU's benchmark percentile is 90th among all CPUs, while the GPU's percentile is 92nd among all GPUs, indicating both components are high performers in their respective categories.

Q: Is the CPU or GPU the primary bottleneck at 1080p?

A: The 1080p Low result of 462 FPS suggests the CPU is the primary limiter at this resolution, as the GPU is capable of far higher frame rates in other workloads. The scaling from 1080p to 1440p at Low settings (a 27.3% drop) is smaller than the scaling from 1440p to 4K (a 47.6% drop), indicating the GPU becomes progressively more dominant as resolution increases.

Q: What frame rates can be expected with V-sync at 4K?

A: At 4K High, the 88 FPS average exceeds the 60Hz V-sync threshold. At 4K Ultra, the 84 FPS average also exceeds 60Hz. However, the 4K Medium average of 124 FPS with a 106 FPS minimum means that targeting a 120Hz display would be possible but with occasional dips below the refresh rate.

GPU Role

The NVIDIA GeForce RTX 5090 brings substantial resources to this simulation title: 21,760 shading units, 680 texture mapping units, and 176 ROPs operating on a 512-bit memory bus. The 32GB of GDDR7 memory at 1.79 TB/s bandwidth provides extraordinary headroom for any texture or buffer demands this game could present, and the measured data confirms that memory capacity is never a constraint. The GPU's boost clock of 2407 MHz and base clock of 2017 MHz are high for a large Blackwell 2.0 die, and the 104.8 TFLOPS FP32 compute throughput suggests the card can handle far more demanding rendering workloads than this 2019 title presents.

The benchmark results for the RTX 5090 show a passmark G3D score of 39,650 and a 3DMark Steel Nomad DX12 score of 18,355. These synthetic scores place the GPU at the 92nd percentile among all GPUs, and its nearest rivals include the NVIDIA Tesla P100 PCIe 16 GB (0.3% lower average score) and the AMD Radeon RX 6850M XT (1.1% lower). The GPU's passmark DirectX 11 score of 341 and DirectX 12 score of 185 indicate strong API-specific performance, though the game's engine likely leverages older rendering paths given its 2019 release date.

In Pc Building Simulator specifically, the GPU's role becomes more pronounced as resolution increases. The transition from 1080p to 1440p at Medium settings costs 36.9% of the average FPS (377 to 238), while the transition from 1440p to 4K at Medium costs 47.9% (238 to 124). This accelerating drop-off pattern is classic GPU-bound behavior, where the rendering workload grows super-linearly with pixel count. The fact that 4K Low still produces 176 FPS demonstrates the GPU's raw fill-rate capabilities, but the game's engine appears to have ceiling effects that prevent the card from reaching its theoretical maximum frame output.

How This Combo Ranks

The combination of the Intel Core Ultra 5 245 and NVIDIA GeForce RTX 5090 achieves a rank of 44 out of 3,002 tested combos for Pc Building Simulator. This top-1.5% placement is noteworthy because neither component individually reaches the 95th percentile of their respective categories — the CPU sits at the 90th percentile and the GPU at the 92nd. The combination's rank suggests that the game's workload benefits from a balanced pairing where the CPU's 14 cores and 14 threads can feed the GPU's massive rendering pipeline without creating a significant bottleneck.

The CPU's average benchmark score of 48,995 places it within 0.5% of the AMD Ryzen 7 PRO 5755G and AMD Ryzen 9 7900, while being 0.8% ahead of the Intel Core i5-14600K. The GPU's average benchmark score of 79,842 is similarly close to its nearest rivals, with the AMD Radeon Pro Vega 64X being 1.4% higher and the Tesla P100 PCIe 16 GB being 0.3% lower. This tight clustering in synthetic benchmarks suggests that the combo's rank 44 placement is driven by game-specific optimization rather than raw component superiority.

The rank of 44 out of 3,002 means that 2,958 other tested combinations produced lower average FPS in this game. This places the combo in the 98.5th percentile of tested systems for Pc Building Simulator specifically. The fact that both components are in their respective 90th percentiles but the combo reaches the 98.5th percentile of game performance indicates a synergistic pairing where the CPU's strong single-thread performance (Cinebench R23 single-core score of 4,648) complements the GPU's massive parallel throughput.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear progression across quality presets. Low settings produce 462 FPS average, Medium produces 377 FPS with a minimum of 320 and maximum of 433, High produces 266 FPS, and Ultra produces 253 FPS. The step from Low to Medium is a 18.4% reduction, while the step from Medium to High is a 29.4% reduction, and High to Ultra is a 4.9% reduction. The small difference between High and Ultra (13 FPS) suggests that the Ultra preset's additional effects have diminishing returns at this resolution.

At 2560x1440, the pattern shifts. Low produces 336 FPS, Medium produces 238 FPS with a 202 minimum and 274 maximum, High produces 168 FPS, and Ultra produces 160 FPS. The drop from Low to Medium is 29.2%, Medium to High is 29.4%, and High to Ultra is 4.8%. The similarity in percentage drops between 1080p and 1440p for the Medium-to-High transition indicates a consistent scaling factor for quality settings regardless of resolution.

At 3840x2160, the results are: Low produces 176 FPS, Medium produces 124 FPS with a 106 minimum and 143 maximum, High produces 88 FPS, and Ultra produces 84 FPS. The Medium-to-High drop is 29.0%, nearly identical to the 29.4% observed at both lower resolutions. However, the High-to-Ultra drop at 4K is 4.5%, slightly smaller than at other resolutions. The minimum FPS at 4K Medium (106) is still well above the 60 FPS threshold, indicating that even the most demanding configuration remains playable.

Settings Recommendations

For players targeting 60 FPS as a baseline, every measured configuration exceeds this threshold, including the most demanding 4K Ultra setting at 84 FPS. This means that resolution and quality choices can be driven by display capabilities and visual preference rather than performance constraints. For 4K displays, the Medium preset's 124 FPS average with a 106 FPS minimum provides the best balance of visual quality and frame rate stability, particularly for displays with 120Hz refresh rates where the minimum FPS stays above 100.

At 1440p, the High preset's 168 FPS average and the Ultra preset's 160 FPS average are both excellent options for high-refresh-rate displays. The difference between these two presets is only 8 FPS, making Ultra the recommended choice for 1440p users with 144Hz or 165Hz monitors, as the visual quality improvement comes at minimal performance cost. The Medium preset's 238 FPS average with a 202 FPS minimum is the best option for 240Hz displays, where the higher minimum ensures consistent frame delivery.

For 1080p, the Ultra preset's 253 FPS and High preset's 266 FPS both exceed the refresh rate capabilities of virtually all monitors on the market. The Medium preset's 377 FPS average with a 320 FPS minimum provides the highest frame rate stability, but the visual quality trade-off is substantial. Given that the difference between High and Ultra at 1080p is only 13 FPS, Ultra is the reasonable default choice for this resolution, with Medium reserved for players using 360Hz or faster displays who prioritize maximum frame throughput.

CPU Role

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor from the Core Ultra Series 2, built on Arrow Lake architecture with a 3nm process node. Its base clock of 3.50 GHz boosts to 5.10 GHz, and it carries 24 MB of shared L3 cache alongside 3 MB L2 per core and 192 KB L1 per core. The CPU's Cinebench R23 scores of 32,924 multi-core and 4,648 single-core place it at the 90th percentile among all CPUs, with its average benchmark score of 48,995 being within 0.8% of the Intel Core i5-14600K and 0.5% of the AMD Ryzen 9 7900.

In Pc Building Simulator, the CPU's role is most apparent at lower resolutions where the GPU is not fully saturated. The 1080p Low result of 462 FPS suggests that the CPU's single-thread performance (Cinebench R15 single-core score of 468, Passmark single-thread score of 4,394) is sufficient to drive frame rates well beyond typical display refresh rates. The 14 cores and 14 threads provide substantial multi-threading capability, evidenced by the Passmark multithread score of 38,706 and the Cinebench R20 multi-core score of 13,828, which helps with the game's simulation logic that runs concurrently with rendering.

The CPU's memory bandwidth of 102.4 GB/s over dual-channel DDR5, combined with 24 MB of L3 cache, provides adequate data throughput for the game's asset streaming and physics calculations. The fact that the combo ranks 44th out of 3,002 with the CPU at the 90th percentile suggests that the processor is not the limiting factor at higher resolutions, but rather the game's engine scaling characteristics determine overall performance. The CPU's 65W TDP and 5.10 GHz boost clock indicate that it maintains high clock speeds under load, which is beneficial for the game's likely single-thread-heavy simulation components that cannot be fully parallelized across all 14 cores.
