Rust

Rust places heavy demands on both processor and graphics hardware, and the Intel Core i7-14700KF paired with the Intel Arc B390 illustrates a profound imbalance. The benchmark data shows this combo ranks 2601st out of 2953 tested combinations, placing it in the bottom 12% of all systems measured for this survival title. The CPU is a high-end part, but the integrated graphics solution drags the entire experience down to near-unplayable levels at higher resolutions. This analysis breaks down the measured performance across all tested settings, explains the CPU and GPU roles, and provides actionable guidance based strictly on the numbers.

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

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. It features 33 MB of shared L3 cache and 2 MB of L2 cache per core, which are substantial resources for a game like Rust that is known for heavy server-side simulation and complex world interactions. The CPU's benchmark scores reflect its high-end positioning: it achieves a Cinebench R23 multicore score of 44167 and a single-core score of 6235, placing it in the 94th percentile of all CPUs tested. Its average benchmark score of 70163 puts it just 0.2% ahead of the AMD Ryzen 7 9700F, 0.4% ahead of the AMD Ryzen 9 7940HX, and 0.9% ahead of the AMD Ryzen 9 7950X, while trailing the Intel Core Ultra 7 265K by 1%.

In Rust, the CPU handles the game's simulation tick rate, entity updates, and physics calculations. The data suggests that this processor is more than capable of feeding the graphics subsystem with draw calls and world data. However, the measured FPS in this combo tells a different story: at 1080p Low, the system reaches 76 FPS, which is the highest average recorded across all settings. This indicates that even at the lowest graphical preset, the CPU is not the primary bottleneck — the integrated GPU is. The processor's high single-thread performance (Cinebench R15 single-core score of 628, Geekbench single-core score of 2578) is crucial for Rust's main thread, but with a GPU that ranks in the 9th percentile of all GPUs, the CPU's potential is severely underutilized. The data shows that the CPU's 125 W TDP and 10 nm process node contribute to its ability to sustain high clocks, but none of that matters when the graphics pipeline cannot keep up.

Settings Recommendations — which preset gives the best experience per the measured rows

Based solely on the measured FPS values, the only playable configuration for this combo is at 1080p with Low settings, where the average FPS is 76. This is the only tested row that exceeds 60 FPS, which is generally considered the minimum for a smooth experience in a fast-paced survival game. At 1080p Medium, the average drops to 51 FPS with a minimum of 44 and a maximum of 59, which is borderline but may be acceptable for less action-heavy moments. The 1080p High preset yields 43 FPS, and Ultra drops to 33 FPS, both of which are below the 60 FPS threshold and will likely result in noticeable stutter during combat or when multiple players are on screen.

At 1440p, the situation deteriorates significantly. The Low preset averages 53 FPS, which is playable but not smooth, while Medium averages 35 FPS with a minimum of 30. High and Ultra at 1440p average 30 and 23 FPS respectively, making them unsuitable for anything but static screenshots. At 4K, even Low settings only manage 31 FPS, and Medium drops to 21 FPS with a minimum of 18 and a maximum of 24. The recommendation from the data is unambiguous: for any semblance of playable performance, users must select 1080p Low. If visual fidelity is prioritized over frame rate, 1080p Medium offers the best compromise between the measured 51 FPS average and improved graphics, but users should be prepared for drops to 44 FPS. All higher settings or resolutions are effectively unplayable based on the measured averages.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Intel Core i7-14700KF and Intel Arc B390 achieves a rank of 2601 out of 2953 tested combos in Rust. This places the system in the bottom 12.0% of all configurations measured, which is a remarkably poor result given the CPU's capabilities. The CPU alone sits in the 94th percentile of all processors, with an average benchmark score of 70163 that is competitive with top-tier AMD and Intel parts. For instance, it is 0.2% ahead of the AMD Ryzen 7 9700F and 0.9% ahead of the AMD Ryzen 9 7950X, both of which are high-performance desktop processors. The discrepancy between the CPU's percentile and the combo's rank highlights the GPU as the sole reason for this poor standing.

The GPU, by contrast, ranks in the 9th percentile of all GPUs, with a 3DMark Steel Nomad DX12 score of 1482. Its nearest rivals are all legacy NVIDIA parts from a decade ago, such as the GT 520MX and GT 710, which underscores how far behind modern standards this integrated solution is. In Rust, which is a demanding title that stresses both CPU and GPU, the combo's rank of 2601 reflects the reality that the GPU cannot translate the CPU's massive compute potential into playable frame rates. The gap between the CPU's high percentile and the combo's low rank is one of the largest possible in the database, indicating a severe hardware mismatch.

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

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, built on Intel's 3 nm process node. It has a base clock of 300 MHz and a boost clock of 2500 MHz, with 1536 shading units, 48 texture mapping units, and 24 raster output units. It features 12 ray tracing cores and supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Critically, the memory configuration is marked as "System Shared," meaning it has no dedicated VRAM and instead relies on the system's main memory, with bandwidth described as "System Dependent." The GPU's total board power is 80 W, and it is integrated into the processor package, using the system's existing memory bandwidth.

The measured FPS data shows a clear correlation between the GPU's limited resources and Rust's performance. At 1080p Low, the system averages 76 FPS, but this drops to 51 FPS at Medium, 43 FPS at High, and 33 FPS at Ultra. This steep decline indicates that the GPU's shading units and texture units are overwhelmed as the game's draw distance, texture quality, and post-processing effects increase. The shared memory bandwidth is also a likely culprit, as Rust's large open world requires constant streaming of terrain and building data. At 4K, the GPU's 24 ROPs and shared memory are completely inadequate, resulting in an average of 18 FPS at High settings. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are theoretically sufficient for 1080p, but the measured data shows that even this resolution is borderline at best, with the GPU ranking just 1.3% above the GT 520MX in raw compute.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data covers three resolutions and four settings presets, providing a comprehensive view of the combo's performance envelope.

At 1920x1080, the system achieves its best results. Low settings average 76 FPS. Medium settings average 51 FPS, with a minimum of 44 and a maximum of 59, indicating some frame pacing instability. High settings average 43 FPS. Ultra settings average 33 FPS. The progression from Low to Ultra shows a decline of 43 FPS, with each step up in quality costing roughly 8-10 FPS on average.

At 2560x1440, the performance drops significantly across all presets. Low settings average 53 FPS, which is a 30% reduction from the 1080p Low result. Medium settings average 35 FPS, with a minimum of 30 and a maximum of 41. High settings average 30 FPS, and Ultra settings average 23 FPS. The gap between Low and Ultra at 1440p is 30 FPS, which is smaller in absolute terms but proportionally similar to the 1080p results.

At 3840x2160, the system is essentially unplayable. Low settings average 31 FPS. Medium settings average 21 FPS, with a minimum of 18 and a maximum of 24. High settings average 18 FPS. Ultra settings average 13 FPS. The 4K results show that even the lowest preset cannot maintain 30 FPS, and the Ultra preset is below 15 FPS, which is a slideshow experience. The lack of min/max data for Low, High, and Ultra at 4K and 1440p suggests that the frame times are too inconsistent to reliably measure, further confirming the GPU's inability to handle the workload.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The resolution scaling data reveals a classic GPU-bound profile. Moving from 1920x1080 to 2560x1440 at Low settings, the average FPS drops from 76 to 53, a 30% reduction. Moving from 1440p to 4K at Low settings, the average drops from 53 to 31, a 41% reduction. Combined, the 1080p to 4K transition at Low settings results in a 59% decrease in average FPS (from 76 to 31). At Medium settings, the drop is from 51 FPS at 1080p to 21 FPS at 4K, a 59% reduction as well. At High settings, the drop is from 43 FPS to 18 FPS, a 58% reduction. At Ultra settings, the drop is from 33 FPS to 13 FPS, a 61% reduction.

These consistent ~60% reductions across all settings when moving from 1080p to 4K are characteristic of a system where the GPU is the primary bottleneck. The pixel count quadruples from 1080p to 4K, and the FPS roughly halves, which is expected for a GPU that is already near its limits at 1080p. If the CPU were the bottleneck, the FPS would remain relatively flat as resolution increases, because the CPU would be the limiting factor regardless of resolution. The data shows the opposite: FPS scales inversely with resolution, proving that the Intel Arc B390's shared memory bandwidth and limited ROPs are the limiting components. The CPU's high benchmark scores are irrelevant at higher resolutions because the GPU cannot process the additional pixels fast enough. The 4K results, particularly the 13 FPS average at Ultra, highlight that this combo is only viable for 1080p Low, and even that is marginal given the GPU's 9th percentile ranking.
