CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i7-12700KF brings substantial processing power to this pairing, built on the Alder Lake architecture and manufactured on Intel's 10 nm process. This 12-core, 20-thread processor features a base clock of 3.60 GHz and a boost clock of 5.00 GHz, with a 125 W TDP that classifies it as a high-performance desktop part. The cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 25 MB of shared L3 cache, providing ample on-die storage for game data. The processor supports both DDR4 and DDR5 memory across a dual-channel bus and connects to the system via PCIe Gen 4 with 20 CPU lanes. Released in November 2021 with a launch MSRP of $384, this chip sits in the 85th percentile of all CPUs in the database, indicating it outperforms the vast majority of processors tested.

The CPU's synthetic benchmark results confirm its strength across both single-threaded and multi-threaded workloads. In Cinebench R23, it scores 28838 points in multi-core and 4071 points in single-core, while Geekbench shows 14367 multi-core and 2255 single-core. The 3DMark suite reveals scaling from 1043 in single-thread to 9282 in 16-thread and 9983 in max-thread tests. PassMark results include 34092 in multithread and 3984 in single-thread, with particularly strong integer math performance at 113521 and floating-point math at 87449. The average benchmark score of 35365 places it in a tight cluster with its nearest rivals: the Intel Core i7-13700T scores 35403 (0.1% higher), the Intel Core 5 213PE scores 35428 (0.2% higher), while the Intel Core i5-13600T scores 35305 (0.2% lower) and the Intel Core i7-12700K scores 35287 (0.2% lower). This essentially four-way tie at the top of the CPU performance chart means the 12700KF provides no meaningful advantage or disadvantage relative to its closest competitors in this game.

In Pc Building Simulator specifically, the CPU's role is largely theoretical, as the game's simulation and rendering workloads clearly do not stress this processor to anywhere near its limits. The measured FPS data shows that even at 1920x1080 with Low settings, where CPU load would be proportionally highest, the system only achieves 125 FPS average. This is far below what this CPU could deliver with a more capable graphics card, suggesting the game's logic and physics are simple enough that the 12700KF has headroom to spare. The 20 threads and 5.00 GHz boost clock provide far more processing capacity than this title requires, making the CPU a non-factor in the performance equation. The real constraint lies entirely with the GPU, which cannot translate the CPU's capabilities into higher frame rates.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B390 presents an extreme contrast to the CPU in this pairing. This is an integrated graphics processor based on the Panther Lake chip with Xe3-LPG architecture, manufactured on a 3 nm process. Its specifications reveal its integrated nature: the memory size, type, and bus width are all listed as "System Shared," with bandwidth described as "System Dependent." The GPU features 1536 shading units, 48 texture mapping units, and 24 render output units, along with 12 ray tracing cores. Clock speeds run from a 300 MHz base to a 2500 MHz boost, producing a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. Compute performance reaches 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16, while the TDP is a modest 80 W with no power connectors required. The bus interface is listed as IGP, confirming its integrated nature, and it supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The GPU's benchmark results are remarkably weak, placing it in only the 9th percentile of all GPUs. Its sole 3DMark Steel Nomad DX12 score of 1482 puts it in direct competition with ancient discrete graphics cards: the NVIDIA GeForce GT 520MX scores 1463 (1.3% lower), the GeForce 800M scores 1460 (1.5% lower), the GeForce GT 625 OEM scores 1446 (2.5% lower), and the GeForce GT 710 scores 1443 (2.7% lower). This places the Arc B390 at the very bottom of the GPU performance hierarchy, roughly equivalent to entry-level graphics solutions from over a decade ago. The average benchmark score of 1482 confirms this assessment, and the 80 W TDP alongside the IGP form factor indicates this is not designed for gaming performance but rather for basic display output in portable or low-power systems.

In Pc Building Simulator, the Arc B390's limitations become immediately apparent. The measured frame rates show that even at the lowest settings and resolution, the GPU cannot maintain high performance. At 1920x1080 Low, the system averages 125 FPS, but this drops to 88 FPS at Medium, 62 FPS at High, and 59 FPS at Ultra. At 2560x1440, the same progression yields 79, 56, 39, and 38 FPS respectively. At 4K, the results fall to 41 FPS at Low, 29 FPS at Medium, 21 FPS at High, and 20 FPS at Ultra. The pattern is clear: the GPU's limited shading units, texture units, and ROPs cannot handle the increasing pixel count and visual complexity as settings rise. The system-shared memory also means the GPU competes with the CPU for bandwidth, though this game's modest requirements likely mitigate that concern. The Arc B390 is the definitive bottleneck, restricting performance to levels that would be considered unplayable at higher settings.

Settings Recommendations

The measured FPS data across all resolutions and settings shows that this combo struggles to maintain playable frame rates in most configurations. At 1920x1080, the Low preset delivers 125 FPS average, which is the only setting that provides a clearly smooth experience. Medium drops to 88 FPS, which remains playable but shows a 29.6% performance reduction. High falls to 62 FPS, a level that may be acceptable but is approaching the threshold where frame pacing becomes noticeable. Ultra produces 59 FPS, only slightly below High but representing a 52.8% reduction from Low.

At 2560x1440, the situation becomes more constrained. Low gives 79 FPS, which is playable, while Medium drops to 56 FPS and both High and Ultra fall to 39 and 38 FPS respectively. These lower values indicate that the Arc B390 cannot sustain high refresh rates at this resolution. At 3840x2160, all settings produce sub-60 FPS results, with Low at 41 FPS, Medium at 29 FPS, High at 21 FPS, and Ultra at 20 FPS. The Medium setting at this resolution has recorded min/max values of 25 and 34 FPS, showing noticeable variance.

Given these measurements, the best experience comes from the 1920x1080 Low preset, which provides 125 FPS average and ensures smooth gameplay for this simulation title. Users prioritizing visual quality over frame rate could consider Medium at this resolution, which maintains 88 FPS while offering improved graphics. The data does not support using High or Ultra at any resolution, as these settings consistently drop below 62 FPS even at 1080p. At 1440p, Low is the only recommended setting at 79 FPS, while 4K should be avoided entirely as even Low fails to reach 60 FPS. The measured data indicates that this combo's optimal operating point is 1080p Low, with 1080p Medium as a secondary option for those who prefer better visuals at the cost of 37 FPS.

How This Combo Ranks

The Intel Core i7-12700KF + Intel Arc B390 combination ranks 2650th out of 3002 tested combos in Pc Building Simulator, placing it in the bottom 11.7% of all configurations tested. This ranking is remarkable given the CPU's strong specifications and benchmark performance. The 12700KF sits in the 85th percentile of all CPUs, yet the system as a whole performs near the bottom of the database. This discrepancy highlights the extreme imbalance between the two components: the CPU has massive processing headroom that the GPU cannot utilize, while the GPU's 9th percentile ranking drags the entire system down.

The ranking makes sense when considering the GPU's nearest rivals, which are all integrated or entry-level discrete graphics solutions from the early 2010s. The Arc B390's performance level is comparable to the NVIDIA GeForce GT 710 or GT 625 OEM, both of which would be considered obsolete for modern gaming. In a simulation game like Pc Building Simulator, which likely has moderate GPU requirements, this level of graphics performance is insufficient for anything beyond low-end settings. The rank of 2650 reflects this reality: most other tested combos, even those with weaker CPUs, likely have more balanced GPU performance that allows for better overall frame rates.

The contrast between the CPU's position and the combo's position is instructive. A CPU in the 85th percentile paired with a GPU in the 9th percentile produces a system that ranks in the bottom 12th percentile overall. This nonlinear relationship shows that in gaming workloads, the GPU's contribution to overall performance far outweighs the CPU's, especially when the GPU is as weak as the Arc B390. Users considering this pairing should understand that the CPU's capabilities will be almost entirely wasted in this game, as the GPU will cap performance at levels far below what the processor could support with a more capable graphics card.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this combo's performance across three resolutions and four quality settings. At 1920x1080, the system achieves its best results: Low settings produce 125 FPS average, Medium produces 88 FPS with a minimum of 75 and maximum of 102, High produces 62 FPS, and Ultra produces 59 FPS. The progression from Low to Ultra shows a 52.8% reduction in average frame rate, with the largest single drop occurring between Low and Medium at 37 FPS. The gap between High and Ultra is minimal at just 3 FPS, suggesting diminishing returns from the highest preset.

At 2560x1440, performance drops significantly across all settings. Low produces 79 FPS average, Medium produces 56 FPS with a range of 47 to 64, High produces 39 FPS, and Ultra produces 38 FPS. The reduction from 1080p to 1440p at Low settings is 46 FPS, a 36.8% decrease. At Medium, the drop is 32 FPS, and at High and Ultra, the drops are 23 and 21 FPS respectively. This resolution represents a significant step down in playability, with only Low remaining above 60 FPS.

At 3840x2160, the system falls below playable thresholds at every setting. Low produces 41 FPS average, Medium produces 29 FPS with a minimum of 25 and maximum of 34, High produces 21 FPS, and Ultra produces 20 FPS. The 4K resolution proves too demanding for the Arc B390, with even Low settings failing to reach 60 FPS. The Medium setting at this resolution shows the only recorded variance data, with a range of 9 FPS between minimum and maximum values. Across all resolutions and settings, the data reveals a consistent pattern: the Arc B390's performance scales predictably with pixel count and quality level, but its absolute performance is too low to provide a satisfactory experience at anything above 1080p Low or Medium. The system's overall performance in this game is directly tied to the GPU's limitations, with the CPU's considerable resources remaining untapped throughout all measured configurations.
