Rust

The Intel Core Ultra 5 245 paired with the Intel Arc B390 is a combination that the database has measured running Rust at rank 3312 out of 3723 tested combos. That places it in the lower portion of tested systems, with only a small number of combos performing worse. The game, a survival title released in 2018, demands more from the graphics subsystem than this integrated-class GPU can deliver at higher resolutions, while the CPU side remains comparatively strong. The recorded data shows a system that clears the 60 FPS playable threshold only at 1920x1080 with Low settings, where it reaches 76 FPS average.

How This Combo Ranks

The combo rank of 3312 out of 3723 means this pairing sits in the lower portion of the database for Rust. The rank is driven primarily by the GPU: the Arc B390 sits in the 9th percentile among all GPUs, with an average benchmark score of 1482 in 3DMark Steel Nomad DX12. By contrast, the Core Ultra 5 245 sits in the 90th percentile among all CPUs, with an average benchmark score of 48995. The CPU has a launch MSRP of $270.

The discrepancy between CPU and GPU performance is the defining feature of this combo. The CPU's multi-threaded Cinebench R23 score of 32924 and single-thread score of 4648 are both strong, placing it well above most desktop processors. The GPU, however, is a low-power integrated part (80 W TDP, IGP slot width, system-shared memory) that trails nearly every discrete graphics card in the database. In Rust, a game that stresses both geometry and shading, the GPU becomes the limiting factor at every resolution above 1080p Low.

The measured frame rates confirm this pattern. At 1920x1080 Low, the system averages 76 FPS, but at 2560x1440 Low it drops to 53 FPS, and at 3840x2160 Low it falls to 31 FPS. The steep decline with resolution is characteristic of GPU-bound rendering, where the pixel and texture throughput of the graphics part determines the ceiling.

Best Settings per Resolution

For each resolution, the most demanding preset that stays at or above 60 FPS is reported here.

At 3840x2160, no preset reaches 60 FPS. The highest measured average is 31 FPS at Low settings, with Medium at 21 FPS, High at 18 FPS, and Ultra at 13 FPS. The database lists no playable settings for 4K.

At 2560x1440, no preset clears 60 FPS. Low settings average 53 FPS, Medium 35 FPS, High 30 FPS, and Ultra 23 FPS. The verdict records no playable settings at this resolution.

At 1920x1080, Low settings are the only playable preset, averaging 76 FPS. Medium averages 51 FPS, High 43 FPS, and Ultra 33 FPS. The best settings for 1080p is therefore Low, with the measured average of 76 FPS.

Similar Performance Alternatives

The nearest rivals for the CPU, based on average benchmark score, are all within 0.8 percentage points of the Core Ultra 5 245. The AMD Ryzen 7 PRO 5755G scores 49196, just 0.4% below the Ultra 5's 48995. The AMD Ryzen 9 7900 scores 49228, 0.5% below. On the Intel side, the Xeon Gold 5318H scores 48698, 0.6% above, and the Core i5-14600K scores 48618, 0.8% above. In Rust, where CPU load is moderate at lower resolutions, any of these processors would produce nearly identical frame rates when paired with the same GPU.

For the GPU, the nearest rivals are all older NVIDIA parts. The GeForce GT 520MX scores 1463, 1.3% below the Arc B390's 1482. The GeForce 800M scores 1460, 1.5% below. The GeForce GT 625 OEM scores 1446, 2.5% below, and the GeForce GT 710 scores 1443, 2.7% below. These parts would deliver frame rates within a few percent of the Arc B390 in Rust, meaning they would also fail to reach 60 FPS at 1440p and above.

A user upgrading from one of these GPU rivals to the Arc B390 would see gains between 1.3% and 2.7%. Similarly, swapping the CPU for any of its rivals would change Rust performance by 0.8% or less.

Measured FPS Breakdown

The full set of recorded measurements for Rust with this combo is as follows.

At 3840x2160:

• High: 18 FPS average
• Low: 31 FPS average
• Medium: 21 FPS average, with a minimum of 18 FPS and maximum of 24 FPS
• Ultra: 13 FPS average

At 2560x1440:

• High: 30 FPS average
• Low: 53 FPS average
• Medium: 35 FPS average, with a minimum of 30 FPS and maximum of 41 FPS
• Ultra: 23 FPS average

At 1920x1080:

• High: 43 FPS average
• Low: 76 FPS average
• Medium: 51 FPS average, with a minimum of 44 FPS and maximum of 59 FPS
• Ultra: 33 FPS average

The only configuration with a recorded average above 60 FPS is 1920x1080 Low, at 76 FPS. The Medium preset at 1080p has a maximum of 59 FPS, which still falls below the playable threshold. At 1440p, the Low preset averages 53 FPS, below 60. At 4K, all presets are far below playable.

The data shows a consistent pattern: each step down in resolution from 4K to 1440p to 1080p raises the frame rate at Low settings from 31 to 53 to 76 FPS. This is a classic GPU-bound scaling curve, where halving the pixel count produces a substantial frame rate increase.

The Verdict

The database verdict for this combo is clear. At 3840x2160, no settings are playable; the best average is 31 FPS at Low. At 2560x1440, no settings are playable; the best average is 53 FPS at Low. At 1920x1080, Low settings are playable with a 76 FPS average, and this is the only playable configuration across all resolutions.

In short, this PC can run Rust, but only at 1080p with Low settings. The 60 FPS threshold is cleared at that preset. Any attempt to raise the resolution or the quality preset will drop the frame rate below playable levels. The Medium preset at 1080p averages 51 FPS, below the threshold, and its maximum of 59 FPS means it never reaches 60 FPS in the recorded data.

For a survival game like Rust, where responsiveness matters during player encounters, the 1080p Low preset is the only viable option. At 1440p, the 53 FPS average at Low might be tolerable for some, but it does not meet the 60 FPS standard used in this database.

CPU and GPU Roles

The division of labor in this combo is stark. The CPU, Intel Core Ultra 5 245, ranks in the 90th percentile of all CPUs in the database. Its Cinebench R23 multi-core score of 32924 and single-core score of 4648 place it among strong desktop processors. The GPU, Intel Arc B390, ranks in the 9th percentile of all GPUs, with a 3DMark Steel Nomad DX12 score of 1482. This is an integrated graphics part (IGP slot width, system-shared memory, 80 W TDP) that is not designed for demanding 3D workloads.

In Rust, the bottleneck is overwhelmingly the GPU. Evidence comes from the resolution scaling. At 1080p Low, the system averages 76 FPS. At 1440p Low, that drops to 53 FPS. At 4K Low, it drops to 31 FPS. If the CPU were the limiting factor, the frame rate would stay roughly constant across resolutions, because the CPU workload in Rust does not scale with resolution the way the GPU workload does. Instead, the frame rate falls steeply as resolution increases, which is the signature of a GPU-bound system.

The CPU's strength does show at 1080p Low, where 76 FPS is a respectable result for this GPU class. The CPU's high single-thread performance (4648 in Cinebench R23 single-core, 4394 in Passmark single-thread) helps maintain decent frame pacing in Rust's simulation-heavy gameplay. But at higher resolutions, the GPU's limited pixel throughput (60 GPixel/s) and texture rate (120 GTexel/s) become the hard ceiling.

The conclusion is that for Rust, this system is GPU-limited at all resolutions above 1080p Low. Users who want better frame rates at 1440p or higher would need to replace the Arc B390 with a discrete GPU. The CPU has ample headroom, as evidenced by its 90th percentile ranking and its rivals all being within 0.8% of its average score, meaning the CPU is not the constraining factor.
