# Pc Building Simulator: Intel Core Ultra X7 368H + NVIDIA GeForce RTX 5080

Pc Building Simulator, a simulation title from 2019, presents an unusual workload that exercises both the CPU and GPU in ways distinct from typical action games. The benchmark data for this combo, pairing Intel's Core Ultra X7 368H mobile processor with NVIDIA's RTX 5080, reveals a configuration that scales impressively across resolutions but shows clear signs of CPU limitation at lower settings. The measured frames per second across all twelve tested configurations—three resolutions and four quality presets—provide a complete picture of where this pairing excels and where it leaves performance on the table.

CPU Role

The Intel Core Ultra X7 368H is a 16-core, 16-thread mobile processor based on the Panther Lake architecture, built on Intel's 3 nm process node. It operates with a base clock of 2.00 GHz and a boost clock of 5.00 GHz, with a TDP of just 25 W—an unusually low power envelope for a chip with this many cores. The cache hierarchy includes 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. Memory support is LPDDR5X over a dual-channel bus, providing 153.6 GB/s of bandwidth.

In Pc Building Simulator, the CPU's role is substantial. This is a simulation game where the player constructs and manages PCs, meaning there is significant logic, inventory management, and system-state calculation happening beyond just rendering frames. The benchmark data supports the notion that the CPU can become a bottleneck at high frame rates. Looking at the 1080p results, the difference between Low and Ultra settings is stark: from 362 FPS at Low down to 172 FPS at Ultra. This 190 FPS gap at the same resolution indicates that at lower settings, the GPU is rendering frames so quickly that the CPU cannot keep up, capping performance. The 16 cores with only 16 threads (no hyperthreading) are adequate for this workload, but the relatively modest L3 cache of 18 MB shared across all cores may limit performance in scenarios with many simultaneous objects.

The processor's benchmark scores place it in the 87th percentile of all CPUs, with an average benchmark score of 40518. Its nearest rivals in the database are the Intel Core 7 253PE (average score 40557, delta -0.1%), the Intel Core 5 223PE (40585, -0.2%), the AMD Ryzen 9 7940H (40431, +0.2%), and the Intel Xeon 6507P (40426, +0.2%). This places the Ultra X7 368H in a tight cluster where the performance differences are within fractions of a percent—essentially a statistical tie with its closest competitors. In multi-threaded workloads, the Cinebench R23 multicore score of 28221 shows strong throughput, while the single-core score of 3984 indicates respectable single-thread performance. The Passmark multithread score of 32956 and single-thread score of 4005 further confirm a balanced profile.

For Pc Building Simulator specifically, the CPU's 16 cores are more than sufficient for the game's simulation logic. The bottleneck appears to be single-thread performance in certain scenarios, as evidenced by the frame rate plateaus at high FPS values. At 1080p Low, the 362 FPS average suggests the CPU is the limiting factor, as modern GPUs of the RTX 5080's caliber can easily exceed this in a simulation game with modest graphics demands. The CPU's integrated Arc B390 graphics are irrelevant here since the discrete GPU handles all rendering, but the presence of this iGPU does not detract from performance.

GPU Role

The NVIDIA GeForce RTX 5080 is a desktop-class graphics card based on the Blackwell 2.0 architecture, built on TSMC's 5 nm process with 45,600 million transistors on a 378 mm² die. It features 16 GB of GDDR7 memory on a 256-bit bus, yielding 960.0 GB/s of bandwidth. The core runs at a base clock of 2295 MHz with a boost clock of 2617 MHz, while memory operates at 1875 MHz (30 Gbps effective). With 10752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores, this is a high-end GPU by any measure. Its FP32 performance of 56.28 TFLOPS and pixel rate of 293.1 GPixel/s demonstrate substantial compute capability.

In Pc Building Simulator, the RTX 5080 is overwhelmingly powerful for the game's visual demands. The GPU's percentile rank of 87 places it among the top GPUs in the database, with an average benchmark score of 56083. Its nearest rivals include the AMD Radeon 8060S (average score 55757, delta +0.6%), the AMD Radeon RX 6750 GRE 12 GB (55698, +0.7%), the AMD Radeon Pro W5700X (54828, +2.3%), and the AMD Radeon RX 9070 GRE (57367, -2.2%). The RTX 5080 sits slightly below the RX 9070 GRE in average score but above all other listed rivals, though the deltas are small—within 2.3% across the entire competitor set.

The GPU's role in this game becomes clear when examining the resolution scaling. At 4K Ultra, the RTX 5080 delivers 57 FPS, which is the only configuration where the GPU is clearly the limiting factor. The 16 GB of VRAM is more than sufficient for this game at any settings—Pc Building Simulator does not require large texture pools, and the memory bandwidth of 960 GB/s ensures no starvation. The boost clock of 2617 MHz enables the card to push extremely high frame rates at lower resolutions, but the game's CPU-bound nature at those settings means the GPU often waits for the processor. In benchmark terms, the RTX 5080's Passmark G3D score of 36565 and Geekbench Vulkan score of 255450 confirm its high-end positioning, though these synthetic numbers do not directly translate to Pc Building Simulator's specific workload.

Resolution Scaling

The measured FPS data reveals a clear pattern of CPU limitation at lower resolutions and GPU limitation at 4K. Starting at 1080p, the average frame rates across settings are: 362 FPS at Low, 256 FPS at Medium, 181 FPS at High, and 172 FPS at Ultra. The drop from Low to Medium is 106 FPS (a 29% reduction), while the drop from Medium to High is 75 FPS (29% further reduction). The gap between High and Ultra is only 9 FPS (5%), suggesting that Ultra settings introduce minimal additional GPU load over High, and both are capped by the CPU.

Moving to 1440p, the pattern shifts. Low delivers 228 FPS, Medium 162 FPS, High 114 FPS, and Ultra 109 FPS. Compared to 1080p, the frame rates drop by 37% at Low (from 362 to 228), 37% at Medium (256 to 162), 37% at High (181 to 114), and 37% at Ultra (172 to 109). This consistent ~37% reduction across all settings at 1440p indicates that the scaling is resolution-driven and GPU-bound, as the CPU headroom at 1080p is being consumed by the increased pixel count.

At 4K, the scaling becomes even more pronounced. Low delivers 119 FPS, Medium 85 FPS, High 60 FPS, and Ultra 57 FPS. From 1440p to 4K, the drops are: 48% at Low (228 to 119), 48% at Medium (162 to 85), 47% at High (114 to 60), and 48% at Ultra (109 to 57). This near-uniform ~48% reduction from 1440p to 4K confirms that the GPU is now the primary bottleneck. The pixel count quadruples from 1080p to 4K, yet frame rates do not drop by 75%—instead, the drop is 67% at Low (362 to 119) and 67% at Ultra (172 to 57). This suggests that even at 4K, there is some CPU involvement preventing a full GPU-bound scaling, or that the game's rendering efficiency improves at higher resolutions.

The data indicates that this combo is CPU-limited at 1080p across all settings, partially CPU-limited at 1440p, and GPU-limited at 4K. The RTX 5080's immense power is wasted at 1080p, where the Core Ultra X7 368H cannot feed frames fast enough. The sweet spot for this pairing appears to be 4K, where the GPU is fully utilized and delivers playable frame rates even at Ultra.

How This Combo Ranks

The combo ranking for this specific CPU-GPU pairing in Pc Building Simulator is 725 out of 3002 tested combos, placing it in the top 24% of all configurations. This ranking reflects the overall performance across all measured resolutions and settings. The 87th percentile positioning of both the CPU and GPU individually does not translate to a top-tier combo ranking, which suggests that the pairing is not optimal for this specific game.

The rank of 725 out of 3002 means there are 724 combos that perform better in Pc Building Simulator. Given that both components are high-end, this relatively modest ranking likely stems from the CPU bottleneck at lower resolutions dragging down the aggregate score. The game's simulation nature means that faster single-thread performance would yield better results, and the Core Ultra X7 368H's 16-core design, while powerful, may not have the per-core speed of some desktop alternatives that could pair with this GPU.

The data shows that the RTX 5080 is not the limiting factor in most configurations. Its rivals in the GPU database—the RX 9070 GRE, Radeon 8060S, and RX 6750 GRE—would likely produce similar frame rates at 1080p and 1440p due to the CPU bottleneck. The combo ranking might improve significantly if paired with a CPU with higher single-thread performance, even if that CPU had fewer cores. This analysis is supported by the CPU's nearest rivals, which all have nearly identical average scores, indicating that the CPU tier is the determining factor for this game's performance ceiling.

Measured FPS Breakdown

At 1920x1080, the measured frame rates are: Low settings produce an average of 362 FPS, Medium settings produce 256 FPS with a minimum of 218 and maximum of 295, High settings produce 181 FPS, and Ultra settings produce 172 FPS. The 1080p results show that Low settings nearly double the frame rate of Ultra, confirming that the game's graphics settings have a substantial impact on GPU load even at this resolution.

At 2560x1440, the frame rates are: Low settings average 228 FPS, Medium settings average 162 FPS with a minimum of 137 and maximum of 186, High settings average 114 FPS, and Ultra settings average 109 FPS. The 1440p results show a more balanced distribution, with Low delivering roughly double the frame rate of Ultra, similar to 1080p but at lower absolute numbers.

At 3840x2160, the frame rates are: Low settings average 119 FPS, Medium settings average 85 FPS with a minimum of 72 and maximum of 97, High settings average 60 FPS, and Ultra settings average 57 FPS. The 4K results show the GPU being pushed harder, with the gap between Low and Ultra narrowing to roughly 2.1x (119 vs 57) compared to 2.1x at 1080p (362 vs 172) and 2.1x at 1440p (228 vs 109). This consistent ratio across resolutions suggests that the game's settings scale uniformly, but the absolute frame rates at 4K Ultra dip to 57 FPS, which is below the ideal for competitive play but acceptable for a simulation game.

The Medium settings at each resolution provide the only configurations with min/max frame data. At 1080p Medium, the range is 218-295 FPS (a 77 FPS spread); at 1440p Medium, the range is 137-186 FPS (a 49 FPS spread); at 4K Medium, the range is 72-97 FPS (a 25 FPS spread). The narrowing range at higher resolutions indicates that frame time consistency improves as the GPU becomes the bottleneck, reducing CPU-induced stutter.

Settings Recommendations

For this combination of Intel Core Ultra X7 368H and NVIDIA GeForce RTX 5080, the optimal settings depend on the target resolution and the player's preference for frame rate versus visual fidelity.

At 1920x1080, the data shows that Ultra settings at 172 FPS provide an excellent experience for any display, while High at 181 FPS offers a negligible improvement. Medium at 256 FPS is overkill for most monitors, and Low at 362 FPS is only useful for competitive play where maximum frame rate matters. Given that the CPU is the bottleneck at this resolution, there is no benefit to dropping below High settings—the 9 FPS difference between High and Ultra is within the margin of error, so Ultra is the recommended choice for the best visual quality without sacrificing performance.

At 2560x1440, Ultra at 109 FPS is playable and provides the best visual experience, while High at 114 FPS is nearly identical. Medium at 162 FPS is a good option for those with 144 Hz or 165 Hz monitors who want to stay above the refresh rate. Low at 228 FPS offers no advantage over Medium for most users. The recommendation here is Ultra for visual quality, or Medium if the player has a high-refresh-rate display and prioritizes smoothness over eye candy.

At 3840x2160, the situation is different. Ultra at 57 FPS is below the 60 FPS target and may feel slightly sluggish in a game that requires precise mouse movement for component installation. High at 60 FPS hits the 60 FPS target exactly and is the minimum recommended setting. Medium at 85 FPS is the sweet spot for 4K, providing a comfortable margin above 60 FPS while maintaining decent visual quality. Low at 119 FPS is ideal for players with 120 Hz 4K displays, though the visual trade-off is significant. The data suggests that Medium at 4K is the best balance of frame rate and fidelity, with High as an acceptable alternative for those who prioritize visuals over a frame rate buffer.

Across all resolutions, the Medium preset shows the best frame time consistency, as evidenced by the min/max data. The 1080p Medium range of 218-295 FPS (77 FPS spread) is proportionally smaller than the frame rates themselves, and this consistency carries through to 4K where Medium ranges from 72-97 FPS (25 FPS spread). For a simulation game where precision matters, this consistency is valuable. The recommendation is to run Medium settings at 4K for the best overall experience, or Ultra at 1440p if the player has a monitor with a refresh rate below 120 Hz.
