Rust

Intel Core i7-13700K paired with an Intel Arc B390 in Rust lands at rank 3312 out of 3723 tested combos, placing it in the bottom 11% of all configurations. This is a severely GPU-bound result: the Arc B390's average benchmark score of 1482 puts it in the 9th percentile of all GPUs, and its nearest rivals are legacy NVIDIA parts like the GeForce GT 520MX (1.3% faster) and GeForce 800M (1.5% faster). The CPU, by contrast, is a top-tier performer — its 89th percentile ranking among all CPUs and average score of 46881 make it the clear anchor of this pairing. The data shows a massive bottleneck: the i7-13700K can feed far more frames than the Arc B390 can render, which is why the combo's ranking is so low despite the processor's strength.

How This Combo Ranks

At position 3312 out of 3723, this combo sits in the 11th percentile of tested configurations for Rust. That ranking is driven almost entirely by the GPU, not the CPU. The Arc B390's 3DMark Steel Nomad DX12 score of 1482 is its only benchmark, and that single result places it below 91% of all GPUs. To contextualize, the GPU's nearest rivals in the database are NVIDIA GeForce GT 520MX (1463, 1.3% faster), GeForce 800M (1460, 1.5% faster), GeForce GT 625 OEM (1446, 2.5% faster), and GeForce GT 710 (1443, 2.7% faster). These are all entry-level or legacy parts from a decade ago, which tells you exactly where the Arc B390 sits in the performance hierarchy.

The CPU side tells a different story entirely. The i7-13700K's average benchmark score of 46881 puts it within 0.2% of the AMD Ryzen 9 5900 (46971) and 0.3% of the AMD Ryzen AI 9 HX PRO 375 (47022), while being 0.5% ahead of both the AMD Ryzen 9 7845HX (46654) and Intel Xeon w3-2535 (46653). In raw compute, this processor is competitive with high-end desktop and workstation parts. The gap between CPU and GPU capability is enormous, and in Rust — a game known for heavy server-side and simulation workloads — that gap manifests as a hard frame rate ceiling imposed by the graphics card.

GPU Role

The Intel Arc B390 is an integrated graphics solution built on the Xe3-LPG architecture with a Panther Lake chip, fabricated on Intel's 3 nm process. It operates with a base clock of 300 MHz and a boost clock of 2500 MHz, with memory marked as "System Shared" — meaning it borrows from system RAM rather than having dedicated VRAM. Its memory bus width and bandwidth are also system-dependent, which is a critical limitation for Rust, a game that streams large world maps and textures. The GPU has 1536 shading units, 48 texture mapping units, and 24 raster operation pipelines, along with 12 ray tracing cores. Its theoretical pixel rate is 60.00 GPixel/s and texture rate is 120.0 GTexel/s, with FP32 performance of 7.680 TFLOPS.

The measured FPS data reflects this hardware profile. At 1920x1080 with Low settings, the combo averages 76 FPS — the only playable result in the entire dataset. Step up to Medium at the same resolution, and the average drops to 51 FPS (min 44, max 59). High at 1080p yields 43 FPS, and Ultra falls to 33 FPS. These numbers show a clear pattern: the Arc B390 is only capable of smooth gameplay at the lowest settings, and even then only at 1080p. The system-shared memory architecture means there is no dedicated VRAM pool to buffer textures, which likely contributes to the steep performance cliff as settings increase.

FAQ

Q: Is this combo capable of playing Rust at 1080p?

A: Yes, but only at Low settings, where the measured average is 76 FPS. At Medium, the average drops to 51 FPS (min 44, max 59), which is borderline playable. High and Ultra settings are not recommended, as averages fall to 43 FPS and 33 FPS respectively.

Q: What is the best resolution for this hardware?

A: The data shows 1920x1080 is the only viable resolution. At 2560x1440, even Low settings only produce 53 FPS on average, and at 3840x2160, Low drops to 31 FPS. Higher resolutions quickly become unplayable.

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

A: The Arc B390 scores 1482 in 3DMark Steel Nomad DX12. Its nearest rivals are the NVIDIA GeForce GT 520MX (1463, 1.3% faster), GeForce 800M (1460, 1.5% faster), GeForce GT 625 OEM (1446, 2.5% faster), and GeForce GT 710 (1443, 2.7% faster). It is essentially on par with these legacy parts.

Q: Does the Intel Core i7-13700K bottleneck this GPU?

A: No, the opposite is true. The CPU's average benchmark score of 46881 places it in the 89th percentile of all CPUs, while the GPU sits in the 9th percentile. The GPU is the limiting factor in every measured scenario.

Q: What is the frame time consistency like at Medium settings?

A: At 1080p Medium, the measured range is 44 to 59 FPS, giving a spread of 15 FPS. At 1440p Medium, the range is 30 to 41 FPS, an 11 FPS spread. At 4K Medium, the range is 18 to 24 FPS, a 6 FPS spread. Lower resolutions show more variance.

Q: How does the CPU rank against its nearest competitors?

A: The i7-13700K (46881) is 0.2% behind the AMD Ryzen 9 5900 (46971) and 0.3% behind the AMD Ryzen AI 9 HX PRO 375 (47022). It is 0.5% ahead of both the AMD Ryzen 9 7845HX (46654) and Intel Xeon w3-2535 (46653).

Measured FPS Breakdown

At 3840x2160, the results are uniformly poor. Ultra settings produce an average of 13 FPS. High settings yield 18 FPS. Medium settings average 21 FPS, with a minimum of 18 and maximum of 24. Low settings are the best at this resolution, reaching 31 FPS on average. None of these are playable for a survival game where reaction time matters.

Moving to 2560x1440 improves things marginally. Low settings deliver 53 FPS on average. Medium settings average 35 FPS, with a range of 30 to 41 FPS. High settings drop to 30 FPS. Ultra settings fall to 23 FPS. Only the Low preset at this resolution approaches acceptable playability, and even then, it sits just above the 60 FPS threshold only in the most optimistic interpretation — the average is 53 FPS, not a locked 60.

At 1920x1080, the picture becomes clearer. Low settings deliver a solid 76 FPS average, which is the only measured result that clears the 60 FPS bar. Medium settings average 51 FPS, with a minimum of 44 and maximum of 59. High settings average 43 FPS. Ultra settings average 33 FPS. The progression from Low to Ultra at 1080p shows a consistent drop of roughly 20-25% per settings tier, which is typical of a GPU that lacks dedicated VRAM and relies on shared system memory.

Settings Recommendations

The data strongly indicates that Low settings at 1920x1080 is the only configuration that provides a consistently smooth experience, with a measured average of 76 FPS. This is the recommended starting point for any gameplay session. If you must use Medium settings, the 51 FPS average at 1080p is workable, but the 44 FPS minimum means you will experience stutters in busy scenes, which Rust is prone to during base raids or when many players are online.

At 1440p, Low settings (53 FPS) is the only viable option, but even that is marginal. At 4K, no setting is playable — the best case is 31 FPS at Low, which is below the threshold for a competitive survival shooter. The recommendation is unambiguous: stick to 1080p Low for the best balance of visual clarity and responsiveness. Medium at 1080p is a compromise that sacrifices frame time consistency for slightly better visuals, and the 44 FPS floor makes it a risky choice for PvP encounters.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on Raptor Lake architecture, fabricated on Intel's 10 nm process. It has a base clock of 3.40 GHz and a boost clock of 5.40 GHz, with a TDP of 125 W. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 30 MB of shared L3 cache. It supports DDR4 and DDR5 memory in a dual-channel configuration, with ECC support enabled. The processor uses Intel Socket 1700 and has 20 PCIe Gen 5 lanes from the CPU.

Benchmark results show a well-rounded performer. In Cinebench R23, it scores 30745 in multi-core and 2116 in single-core. PassMark multi-thread score is 45887, with single-thread at 4333. Geekbench scores are 19429 multi-core and 2529 single-core. The 3DMark results show scaling from 2262 (2 threads) to 12412 (max threads), indicating strong multi-threading efficiency. Data compression in PassMark hits 595292, and floating point math reaches 114867.

In Rust, the CPU's role is to handle the simulation, world generation, and server-side logic. The i7-13700K's high single-thread score (2116 in R23, 4333 in PassMark) is critical for the main game thread, while its 16 cores provide headroom for background tasks. However, this capability goes largely unused in this pairing because the Arc B390 caps the frame rate so low. The 89th percentile CPU ranking means the processor is not the limiting factor — the GPU is. If you were to pair this CPU with a stronger GPU, the data suggests it would scale well, but with the Arc B390, the processor's power is locked behind the graphics card's 9th percentile performance.
