Rust

Rust has always demanded more from hardware than its survival-game label suggests, and this pairing — Intel's Core Ultra X9 388H mobile CPU with NVIDIA's GeForce RTX 4070 Mobile — lands in the middle of the pack for this title. The combo ranks 2039 out of 3723 tested configurations in the benchmark database, placing it just below the median while still delivering playable frame rates at every resolution measured. The data below covers 1080p through 4K across four preset tiers, all captured as real measured results rather than synthetic estimates.

FAQ

Q: Is this combo good for Rust?

A: It is a mid-tier pairing. Of 3723 tested combinations in the database, this one ranks 2039, which places it below the halfway mark. In practice, the measured numbers show 163 FPS at 1080p Low and 70 FPS at 1080p Ultra, so the experience is playable everywhere — but elite configurations rank well above it.

Q: Can it run Rust at 4K?

A: Yes, but with compromises. At 3840x2160 the combo averages 66 FPS on Low, 44 FPS on Medium, 38 FPS on High, and 29 FPS on Ultra. Only the Low preset clears a comfortable threshold; Medium and below that become increasingly marginal.

Q: What CPU is paired here, and how strong is it?

A: The Intel Core Ultra X9 388H is a 16-core, 16-thread mobile processor from the Core Ultra Series 3 (Panther Lake architecture), built on Intel's 3 nm process. It posts a Cinebench R23 multi-core score of 18911 and a single-core score of 2200.5, and it sits in the 88th percentile against all CPUs in the database.

Q: How much VRAM does the GPU have, and is it enough?

A: The RTX 4070 Mobile carries 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s of bandwidth. For Rust at 1080p and 1440p this is not a limiting factor in the measured results; at 4K the frame rates suggest the GPU's raw throughput is the constraint rather than a VRAM cliff.

Q: Does the CPU or GPU limit this game?

A: The scaling pattern points to the GPU. From 1080p to 4K, Medium-settings frame rates fall from 109 to 44 FPS — a drop of roughly 60 percent as pixel count quadruples. A CPU-bound configuration would show much flatter scaling.

Q: How does the GPU compare to rivals?

A: The RTX 4070 Mobile's average benchmark score of 27435 is effectively identical to the AMD Radeon RX 6700 XT (27425, a 0 percent delta), within 0.5 percent of the NVIDIA GeForce RTX 3090, and 1.1 percent ahead of the NVIDIA RTX PRO 4000 Blackwell. It sits in the 73rd percentile of all GPUs.

How This Combo Ranks

A rank of 2039 out of 3723 combinations puts this pairing at roughly the 55th percentile from the top — solidly mid-table for Rust. That positioning is consistent with the individual component profiles. The Core Ultra X9 388H sits in the 88th percentile against all CPUs with an average benchmark score of 44466, essentially tied with the AMD Ryzen 5 7500X3D (44573, a -0.2 percent delta for the Intel part), a hair ahead of the Intel Core i9-13950HX (44342, 0.3 percent delta), the AMD Ryzen AI Max 385 (44309, 0.4 percent), and the Intel Core i5-13600 (44240, 0.5 percent). In other words, the CPU is a strong performer with no meaningful daylight between it and its nearest rivals.

The GPU tells a more middling story. The RTX 4070 Mobile averages 27435 across its benchmark suite, in the 73rd percentile of all GPUs — dead even with the Radeon RX 6700 XT and slightly behind the RTX 3090 (-0.5 percent) and the Radeon Pro Vega 20 (-1.5 percent), while edging the RTX PRO 4000 Blackwell by 1.1 percent. Rust is a title where the GPU does the heavy lifting at higher resolutions, and the combo's below-median rank reflects that: a top-tier CPU cannot fully compensate for a GPU that is merely good.

The takeaway for readers scanning the leaderboard: this configuration will not appear near the top of Rust rankings, but its rank understates the actual experience. The measured frame rates at 1080p and 1440p are entirely serviceable for a survival game where consistent frame delivery matters more than triple-digit refresh rates.

Resolution Scaling

The scaling data is unambiguous: this is a GPU-limited configuration at and beyond 1440p.

At 1080p Medium the combo averages 109 FPS. Move to 2560x1440 and that figure drops to 75 FPS. Push to 3840x2160 and it falls again to 44 FPS. The same cascade appears at every preset. Low goes 163 to 112 to 66. High goes 92 to 64 to 38. Ultra goes 70 to 48 to 29.

Two observations follow. First, the drop from 1080p to 1440p — where pixel count roughly doubles — costs between 31 and 37 percent of the frame rate depending on preset. That is a substantial hit for a doubling of pixels, indicating the RTX 4070 Mobile is already working near capacity at 1080p's higher presets. Second, the 1440p-to-4K transition (another roughly doubling of pixels) costs a similar 38 to 43 percent. The consistency of these losses across presets and resolution steps confirms a graphics-throughput bottleneck rather than a CPU ceiling — a CPU-limited combo would flatten out at higher resolutions.

That said, the CPU is not irrelevant. Rust's 2018 release and survival-genre simulation load mean single-thread responsiveness matters, and the 388H's Cinebench R23 single-core score of 2200.5 and PassMark single-thread score of 4280 provide plenty of headroom. The 1080p Low result of 163 FPS is the closest the data comes to revealing a platform limit, and even there the GPU remains the probable constraint.

Measured FPS Breakdown

All figures below are measured averages from the database.

1920x1080:

• Low: 163 FPS
• Medium: 109 FPS (min 93, max 126)
• High: 92 FPS
• Ultra: 70 FPS

2560x1440:

• Low: 112 FPS
• Medium: 75 FPS (min 64, max 87)
• High: 64 FPS
• Ultra: 48 FPS

3840x2160:

• Low: 66 FPS
• Medium: 44 FPS (min 38, max 51)
• High: 38 FPS
• Ultra: 29 FPS

The Medium preset is the only tier with recorded minimum and maximum frame data, and it reveals respectable frame-time consistency. At 1080p Medium the range runs from 93 to 126 FPS — the minimum sits at about 85 percent of the average, which indicates no severe stutter spikes in the capture. At 1440p Medium the band is 64 to 87, and at 4K Medium it is 38 to 51, both showing the same tight character.

Preset costs are worth noting. At every resolution, dropping from Ultra to High buys a meaningful jump: 70 to 92 at 1080p, 48 to 64 at 1440p, and 29 to 38 at 4K. The step from High to Medium is smaller but still real, while Medium to Low buys the largest single gain at every tier — 46 FPS at 1080p, 37 at 1440p, and 22 at 4K. That steep Medium-to-Low gradient suggests the Low preset disables whole feature groups rather than trimming individual settings, making it the emergency lever when frame rates run short.

GPU Role

The RTX 4070 Mobile is the defining component of this pairing. It is an AD106 chip on TSMC's 5 nm process, packing 22,900 million transistors into a 188 mm² die at a density of 121.8 million transistors per square millimeter. The shader array counts 4608 shading units, 144 texture mapping units, 48 render outputs, 36 RT cores, and 144 tensor cores, with a peak FP32 throughput of 15.62 TFLOPS. Base clock is 1395 MHz with a 1695 MHz boost, and the 8 GB of GDDR6 runs at 2000 MHz — 16 Gbps effective — across a 128-bit bus for 256.0 GB/s of bandwidth.

How does that hardware map onto Rust's results? The texture rate of 244.1 GTexel/s and pixel rate of 81.36 GPixel/s set the theoretical ceilings, and the 4K numbers show the chip running into them. At 3840x2160, Ultra manages only 29 FPS average — a resolution at which the 48 ROPs and modest memory bandwidth are pushed hard by a fully loaded preset. The 128-bit bus is the chip's most obvious constraint at 4K; 256 GB/s is adequate for 1080p and workable at 1440p, but quadrupled pixel counts with high-quality assets strain it.

The 8 GB VRAM buffer deserves a nuanced read. None of the measured results collapse in the pattern typical of VRAM overflow — frame rates scale smoothly with settings at every resolution. If the buffer were saturating at 4K Ultra, the data would more likely show a cliff between Medium and High; instead the decline is gradual (44 to 38 to 29). The evidence points to shader and bandwidth limits, not capacity.

Synthetic results reinforce the mid-range characterization. The PassMark G3D score of 19587, Geekbench OpenCL score of 109197, and Geekbench Vulkan score of 108367 place the chip alongside desktop contemporaries like the RX 6700 XT per the rival table. For a Rust player, that translates into the frame-rate profile documented above: strong at 1080p, comfortable at 1440p with settings discipline, and constrained at 4K.

Settings Recommendations

The measured data supports three clear configurations depending on target resolution.

1080p players should use the High preset. At 92 FPS average, it delivers fluid play while preserving visual quality, and the Ultra preset's 70 FPS — though playable — sacrifices over a fifth of the frame rate for diminishing visual returns. Competitive players who prioritize responsiveness can drop to Medium for 109 FPS or Low for 163 FPS.

1440p players face a genuine choice. Medium's 75 FPS average with a 64 FPS minimum is the safest pick for consistency, but High at 64 FPS average remains playable for a survival title that does not demand twitch-reflex frame rates. Ultra at 48 FPS falls below the comfort line and is best avoided.

4K players should accept the Low preset or reconsider the resolution entirely. Low delivers 66 FPS average — genuinely playable — but Medium's 44 FPS average with a 38 FPS minimum introduces dips that will be felt in combat encounters. High at 38 FPS and Ultra at 29 FPS are not recommended for active gameplay on this hardware.

The broader verdict: this combo is a 1080p-to-1440p machine for Rust. The Core Ultra X9 388H — with 16 threads, a 5.10 GHz boost clock, and benchmark scores within a fraction of a percent of chips like the Ryzen 5 7500X3D and Core i9-13950HX — supplies ample processing power, and the RTX 4070 Mobile converts it into a mid-table but dependable experience. Its rank of 2039 out of 3723 reflects the GPU's 73rd-percentile standing more than any weakness in the platform, and for players satisfied with 1440p Medium play, the data shows a configuration that holds its frame times steady where it matters.
