Rust

This combo pairs the Intel Core i7-14700F with the Intel Arc B390, and in Rust the measured results place it at rank 2601 out of 2953 tested combinations. That is a bottom-decile position, meaning the majority of CPU/GPU pairings in the database produce higher frame rates in this survival title. The i7-14700F is a strong processor on its own, but the Arc B390’s modest graphics throughput becomes the limiting factor, especially at higher resolutions and quality presets. The data indicates that this is a combination suited for lower settings and 1080p play, not for pushing high refresh rates or demanding visual fidelity.

How This Combo Ranks

The combo’s rank of 2601 out of 2953 in Rust places it in the lower 12% of all tested pairings. This is a poor showing for a system built around a 20-core, 28-thread CPU that sits in the 91st percentile among all processors. The disparity between the CPU’s capability and the overall combo’s ranking highlights how heavily the GPU bottlenecks the experience. The Arc B390, with its 3DMark Steel Nomad DX12 score of 1482, lands in the 9th percentile among all GPUs, which is a very low standing. Its nearest rivals in the database are the NVIDIA GeForce GT 520MX (score 1463, delta 1.3%), the NVIDIA GeForce 800M (score 1460, delta 1.5%), the NVIDIA GeForce GT 625 OEM (score 1446, delta 2.5%), and the NVIDIA GeForce GT 710 (score 1443, delta 2.7%). These are not modern gaming cards by any stretch, and the Arc B390 sits just barely above them in raw benchmark performance.

In practical terms, this ranking means that most other CPU/GPU combinations, even those with far weaker processors, will outperform this pairing in Rust because the GPU is the constraining factor. The i7-14700F’s high benchmark scores—Cinebench R23 multi-core at 35122 and single-core at 4958, Geekbench multi-core at 19620 and single-core at 2429—do not translate into high frame rates here. The processor’s Passmark multi-thread score of 41317 and single-thread score of 4257 further confirm its strength, but the GPU cannot keep up. The measured FPS data supports this: at 1080p Low the combo reaches 76 FPS average, which is playable, but at 4K Ultra it drops to 13 FPS, which is effectively unplayable. The ranking reflects this reality, and builders should view this pairing as one that sacrifices graphical quality for the sake of running Rust at all, rather than running it well.

Settings Recommendations

The measured FPS rows provide a clear picture of what settings are viable. At 1920x1080, the Low preset yields an average of 76 FPS, which is the highest average recorded across all settings and resolutions. This is the only configuration that approaches a smooth experience for typical monitors, and it is the recommended starting point. The Medium preset at 1080p drops to 51 FPS average, with a minimum of 44 and maximum of 59, which is still playable but noticeably less fluid. High at 1080p averages 43 FPS, and Ultra averages 33 FPS, both of which may feel stuttery in a game like Rust where player interactions and building mechanics require quick reactions. The data shows a clear trend: each step up in quality costs roughly 20-25% of the frame rate, and the Low preset is the only one that keeps the average above 60 FPS.

Moving to 2560x1440, the situation worsens. Low averages 53 FPS, which is borderline acceptable for some players, but Medium drops to 35 FPS (min 30, max 41), High to 30 FPS, and Ultra to 23 FPS. None of these 1440p settings achieve a 60 FPS average, and even the Low preset is below that threshold. At 3840x2160, the results are poor across the board: Low averages 31 FPS, Medium 21 FPS (min 18, max 24), High 18 FPS, and Ultra 13 FPS. Based on this data, the best experience is clearly at 1080p with the Low preset. If a player insists on higher visual quality, Medium at 1080p is the next viable option, but the average frame rate of 51 FPS indicates that the GPU is already struggling to maintain smoothness. The recommendation is to stick with 1080p Low for competitive play, and only consider Medium if the player can tolerate occasional drops below 45 FPS. Higher resolutions or presets are not recommended, as the frame rates fall below playable thresholds for most users.

FAQ

Q: What is the best resolution and settings combo for this system in Rust?

A: The measured data shows that 1920x1080 with the Low preset yields the highest average FPS at 76. This is the only configuration where the average exceeds 60 FPS, making it the recommended choice. Medium at 1080p averages 51 FPS, which is playable but with a minimum of 44 FPS, while higher presets or resolutions drop below 43 FPS.

Q: How does the Intel Arc B390 compare to its closest GPU rivals?

A: The Arc B390 has a 3DMark Steel Nomad DX12 score of 1482.

The differences are small, indicating the Arc B390 is in the same performance class as these older entry-level GPUs.

Q: Can this system handle 4K gaming in Rust?

A: No. At 3840x2160, the highest average FPS is 31 on Low settings. Medium averages 21 FPS (min 18, max 24), High averages 18 FPS, and Ultra averages 13 FPS. These frame rates are far below what is needed for smooth gameplay, so 4K is not a viable option for this combo.

Q: Is the Intel Core i7-14700F the bottleneck in this system?

A: No, the data suggests the opposite. The i7-14700F ranks in the 91st percentile among all CPUs, with a Cinebench R23 multi-core score of 35122 and a single-core score of 4958. The Arc B390 ranks in the 9th percentile among GPUs, with a 3DMark score of 1482. The GPU is the limiting factor, as evidenced by the low frame rates even at 1080p Low.

Q: What is the expected FPS at 1440p with Medium settings?

A: At 2560x1440 with Medium settings, the measured average FPS is 35, with a minimum of 30 and a maximum of 41. This is below the 60 FPS threshold for smooth play, so it is not recommended for fast-paced gameplay, but it may be acceptable for less demanding activities.

Q: How does this combo’s overall ranking compare to its CPU’s performance percentile?

A: The combo ranks 2601 out of 2953 tested combinations, which is in the bottom 12%. The CPU alone is in the 91st percentile of all processors, showing a massive gap between CPU capability and overall system performance. This gap is due to the GPU’s low standing, as the Arc B390 is in the 9th percentile of all GPUs.

Measured FPS Breakdown

The measured FPS data covers three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings presets (Low, Medium, High, Ultra). At 1920x1080, the results are: Low averages 76 FPS, Medium averages 51 FPS with a minimum of 44 and maximum of 59, High averages 43 FPS, and Ultra averages 33 FPS. This resolution shows the only playable frame rates in the dataset, with Low being the sole preset above 60 FPS. The step from Low to Medium costs 25 FPS on average, a 33% drop, while the step from Medium to High costs 8 FPS, and High to Ultra costs 10 FPS. The minimum FPS data is only available for Medium (44), which suggests that even at this preset, there are noticeable dips that could impact gameplay during intense moments.

At 2560x1440, the averages decline significantly: Low averages 53 FPS, Medium averages 35 FPS (min 30, max 41), High averages 30 FPS, and Ultra averages 23 FPS. The difference between Low and Medium is 18 FPS, and the gap narrows between Medium and High (5 FPS) and High and Ultra (7 FPS). The minimum FPS for Medium (30) indicates that the GPU is hitting a performance wall, as the frame rate can drop to a level that may cause stuttering. None of the 1440p presets reach 60 FPS, and even Low is below that threshold, making this resolution a poor choice for this combo in Rust.

At 3840x2160, the frame rates are uniformly low: Low averages 31 FPS, Medium averages 21 FPS (min 18, max 24), High averages 18 FPS, and Ultra averages 13 FPS. The scaling from Low to Medium is a 10 FPS drop, Medium to High is 3 FPS, and High to Ultra is 5 FPS. The minimum FPS for Medium (18) is barely above what most would consider playable, and the Ultra average of 13 FPS is essentially a slideshow. This resolution should be avoided entirely with this hardware. The data also shows that the difference between 1080p and 1440p at the same settings is substantial; for example, Low at 1080p (76 FPS) versus Low at 1440p (53 FPS) is a 23 FPS drop, while High at 1080p (43 FPS) versus High at 1440p (30 FPS) is a 13 FPS drop. The GPU’s limited pixel throughput is evident in these scaling numbers, and the overall pattern is that the Arc B390 is only capable of providing acceptable performance at the lowest resolution and quality settings.

GPU Role

The Intel Arc B390 is the primary limiting factor in this combo’s Rust performance. Its specifications include a base clock of 300 MHz and a boost clock of 2500 MHz, with 1536 shading units, 48 texture mapping units, and 24 render output units. It also has 12 ray tracing cores, though Rust’s rendering is not heavily dependent on RT features. The GPU’s memory is listed as “System Shared,” meaning it uses the system’s main memory rather than dedicated VRAM, with a bus width and bandwidth also listed as “System Shared” and “System Dependent,” respectively. This architecture is typical of an integrated or very low-end part, and it explains why the GPU performs so poorly in a demanding title like Rust.

The GPU’s 3DMark Steel Nomad DX12 score of 1482 places it at the 9th percentile among all GPUs. Its nearest rivals are the NVIDIA GeForce GT 520MX (score 1463), GeForce 800M (1460), GeForce GT 625 OEM (1446), and GeForce GT 710 (1443). The delta percentages are small—1.3%, 1.5%, 2.5%, and 2.7%, respectively—meaning the Arc B390 is only marginally faster than these decade-old parts. In Rust, this translates to the measured FPS: at 1080p Low, the GPU can push 76 FPS, but at 4K Ultra it drops to 13 FPS. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are not enough to handle higher resolutions with complex scenes, which is why the frame rates fall off so steeply as settings increase.

The GPU’s FP32 performance of 7.680 TFLOPS and FP16 of 15.36 TFLOPS (2:1) are modest figures, and the 80 W TDP suggests it is designed for low-power systems rather than gaming. The bus interface is listed as “IGP” (integrated graphics processor), and the slot width is also “IGP,” confirming that this is not a discrete add-in card. This means the Arc B390 shares system memory with the CPU, and the “System Dependent” bandwidth implies that memory performance can vary based on the rest of the system. In Rust, which is a game that benefits from fast memory and adequate VRAM, this shared memory configuration likely contributes to the low frame rates, especially at higher presets where texture and geometry demands increase. The data shows that the GPU is not up to the task of modern gaming, and builders should set expectations accordingly when pairing it with a high-end CPU.

CPU Role

The Intel Core i7-14700F is a high-performance processor that is largely wasted in this combo due to the GPU bottleneck. It has 20 cores and 28 threads, with a base clock of 2.10 GHz and a boost clock of 5.40 GHz. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The architecture is Raptor Lake, built on Intel’s 10 nm process, and it supports DDR4 and DDR5 memory in a dual-channel configuration. The CPU’s benchmark scores underscore its strength: Cinebench R15 multi-core at 3540 and single-core at 499, Cinebench R20 multi-core at 14751 and single-core at 2082, Cinebench R23 multi-core at 35122 and single-core at 4958, Geekbench multi-core at 19620 and single-core at 2429, and Passmark multi-thread at 41317 with single-thread at 4257. It also excels in specialized workloads like data compression (505885), floating point math (107005), and integer math (155808).

The CPU’s percentile rank among all processors is 91, meaning it outperforms the vast majority of CPUs in the database. Its average benchmark score is 53620, and its nearest rivals are the Intel Xeon 6505P (score 53701, delta -0.2%), the Intel Xeon Phi 7290 (53469, delta 0.3%), the AMD Ryzen 9 7900X (53288, delta 0.6%), and the AMD EPYC 7313P (53206, delta 0.8%). These are all high-end server or desktop parts, and the i7-14700F holds its own against them. In Rust, the CPU’s role is to handle game logic, physics, and the many entities that players build and interact with. The 28 threads provide ample headroom for these tasks, and the 5.40 GHz boost clock ensures strong single-thread performance, which is critical for games that rely on a primary thread.

However, the measured FPS data shows that the CPU’s power does not translate into high frame rates because the GPU cannot render frames fast enough. At 1080p Low, the average FPS is 76, which is likely CPU-bound to some degree, but at higher settings, the GPU becomes the bottleneck. For example, at 1080p Ultra, the FPS drops to 33, and at 4K Ultra, it falls to 13. The CPU’s Passmark physics score of 2455 and the ability to handle data encryption (30144) and extended instructions (28564) suggest it can process game simulation tasks without issue. The launch MSRP for this CPU is $359, and it is a locked multiplier part, so overclocking is not an option to squeeze out more performance. The data indicates that the i7-14700F is not the problem in this system; rather, it is a capable processor that is held back by a GPU that ranks in the 9th percentile. Builders who pair this CPU with a stronger GPU would likely see significantly better results in Rust, but with the Arc B390, the CPU sits idle waiting for the GPU to catch up.
