Rust

Rust, released on 2018-02-07, is a survival game that tends to stress both CPU and GPU as bases grow and draw distance climbs. This page analyses the AMD Ryzen 7 9700X combined with the AMD Radeon RX 6600, using the measured frame-rate data for three resolutions and four quality presets. The data also places this specific combination 2,900th out of 3,723 tested combinations, which puts it in the lower half of the sample.

FAQ

Q: How does this CPU+GPU pair perform in Rust at 1080p?

A: At 1080p the measured average frame rates are 71 fps on High, 54 fps on Ultra, 85 fps on Medium, and 126 fps on Low. The highest preset costs nearly half the frame rate of Low, so the GPU is the main limiter at high quality settings.

Q: What frame times does the Medium preset produce?

A: On 1080p Medium, the minimum was 72 fps and the maximum 97 fps, with an average of 85. At 1440p Medium the min and max are 49 and 67 fps, while at 4K Medium they drop to 29 and 40 fps. These min/max spans show that the 8 GB card's bandwidth becomes tighter as the resolution increases.

Q: Is 4K a viable resolution for this combination?

A: 4K results are low: High averages 29 fps, Medium 34 fps, Low 51 fps, and Ultra 22 fps. Only the Low preset stays above the 30 fps mark, while Medium and High are below 60, confirming that 4K is not a practical target for this GPU.

Q: How does the CPU's core and clock figure into Rust performance?

A: The Ryzen 7 9700X has 8 cores, 16 threads, a base clock of 3.80 GHz, and a boost of 5.50 GHz. Its Cinebench R23 single-core score is 2211 and multi-core 20485, so it has headroom for tightly threaded Rust logic; the act indicates that the GPU becomes the bottleneck as graphical presets rise.

Q: Where does this combination rank relative to other tested combos?

A: The combo is positioned at rank 2,900 out of 3,723 tested combinations. That places it below the median, with roughly 22% of other combinations delivering lower frame rates—or, in other words, the GPU brings the overall result down.

Q: Is the 8GB VRAM an issue for Rust's high-quality textures?

A: With 8 GB of GDDR6 and a 224 GB/s memory bandwidth, the RX 6600 handles the heavier textures in Rust only at the cost of frame rate. Moving from Medium to Ultra at 1080p drops the average from 85 to 54, and at 4K the Ultra preset sits at 22 fps, indicating the memory subsystem is a limit.

How This Combo Ranks

The measured rank for this exact CPU+GPU pair is 2,900th of 3,723 combos in the Rust chart. To interpret: a rank of 2,900 means 2,899 other combinations beat it, leaving only 822 combinations that run slower. Since the database measures every entry the same, the position is driven by the limited GPU more than the CPU.

Benchmark numbers separate the two parts. The CPU sits at the 86th percentile among all CPUs, with an average benchmark score of 37,943 and nearest rivals such as the Intel Core i9-14901E (score 37,911, delta +0.1%) and the AMD Ryzen AI 9 HX 370 (score 37,904, +0.1%). Meanwhile, the RX 6600 ranks at the 63rd percentile for GPUs, with an average score of 19,036 and its direct competition, the NVIDIA Quadro K6000, scoring 19,030 (+0.0%), and the RTX 4050 Mobile at 19,049 (-0.1%). That is a tight cluster: the RX 6600's raw compute is basically side-by-side with those cards, which fits the idea that it is a higher-end 1080p card.

In Rust specifically, the frame-rate table shows that the CPU can push far more than the GPU at low graphics presets. At 1080p Low the combo averages 126 fps, which reflects the CPU's 8-core/16-thread e fortitude. But when the preset goes up, the GPU's moderate architectural bandwidth—the 224 GB/s on a 128-bit bus—limits the sustained output. This is why the B-ranked position is solid, not exceptional: the cores are strong, but the turned frames are just not.

CPU Role

The Ryzen 7 9700X is an 8-core, 16-thread part based on the Zen 5 architecture (Granite Ridge), built on a 4 nm process by TSMC. It runs at a 3.80 GHz base and boosts to 5.50 GHz, with a TDP of 65W. Its 32 MB of L3 cache and dual-channel DDR5 memory with 89.6 GB/s bandwidth matter in Rust because the game needs large world entity caches and frequently allocs server state.

In the benchmark, the CPU demonstrates solid single-thread and multi-thread throughput: Cinebench R23 multi-core score is 20,485 and single-core 2,211. For Rust, which uses one main simulation thread but also distributes physics over multiple threads, the measured FPS following shows that the CPU does not cap the frame rate even at low preset. The 1080p Low average of 126 FPS is close to the game engine's practical ceiling of that graphics configuration, and the 1440p Low (87 FPS) and 4K Low (51 FPS) also reflect a CPU that can keep a headroom if the GPU were stronger.

That said, when the settings climb to Ultra, the CPU stays mostly idle. The 1080p Ultra average of 54 FPS compares to a 126 FPS Low, a gap that cannot be explained by CPU performance. Instead, the GPU becomes the constraint. The 9700X's ability to drive low-overhead draws in Rust is a positive, and that is why the average at 1080p Low is as high as it is; the GPU simply cannot match that when the resolutionc or texture workload increase.

Measured FPS Breakdown

The dataset provides 12 measured combinations of resolution and preset. Each entry is an average frame rate, and for Medium we also get minimum and maximum values.

At 1920x1080:

• Low: 126 FPS
• Medium: 85 FPS (min 72, max 97)
• High: 71 FPS
• Ultra: 54 FPS

At 2560x1440:

• Low: 87 FPS
• Medium: 58 FPS (min 49, max 67)
• High: 49 FPS
• Ultra: 37 FPS

At 3840x2160:

• Low: 51 FPS
• Medium: 34 FPS (min 29, max 40)
• High: 29 FPS
• Ultra: 22 FPS

The 1080p row makes the point: going from Low to Medium loses 41 FPS, from Medium to High loses 14 more, and from High to Ultra drops further to 54. At 1440p the pattern is similar but every preset loses between 28 and 38 FPS when compared to the same setting at 1080p. Comparing to Low-to-Ultra, the pixel scrape is 126 down to 54 FPS at 1080, 87 to 37 at 1440, and 51 to 22 at 4K. The biggest step is between Low and Medium at 1080p (85 vs 126), and that same step is also large at 4K ( 34 vs 51).

Considering the minimums, 1080p Medium keeps a 72 FPS minimum, meaning even the hardest one-percent lows stay above 60. At 1440p Medium the minimum is 49 FPS, and 4K Medium has a 29 FPS minimum. So if your target is 60 FPS stable, the 1080p Low or Medium settings are the only ones that keep the minimum safely clear of 60; 1440p Low ( no min recorded) has a higher average but the unrecorded min could dip below.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture (Navi 23) , 7 nm TSMC. It packs 1,792 shading units, 28 ray accelerators, 64 ROPs, and a 128-bit GDDR6 memory bus with 8 GB of VRAM and 224 GB/s of bandwidth. Its boost clock reaches 2,491 MHz, and at the quickest that is a solid value for 1080p-class loads.

In Rust's measured scenes, the GPU's influence is obvious in two ways. First, the quality reset jumps push the average, and second, the 4K resolutions drop sharply below a usable range. The 8 GB VRAM is enough for 1080p High and Medium textures, but the GPU memory bandwidth of 224 GB/s does not support the heavier 4K texture loads without causing severe frame rate decay. Look at 4K Medium as an example: 34 FPS average, minimum 29, maximum 40 — that is well below a comfortable 60, and even below the 25-th percentile in the database.

The GPU's raw compute number is telling. Its Passmark G3D score of 15,096, and FP32 is 8.928 TFLOPS, puts it in the mid-range bracket. It performs close to the NVIDIA that: the Quadro K6000's benchmark score (19,030) is exactly the same, the RTX 4050 Mobile is 0.1% lower, and the RTX 2000 Ada Generation is 0.4% faster. These results indicate that the RX 6600 is a capable 1920x1080 card where the CPU plays a separate role; for 1440 and 4K it fails to keep the GPU throughput high enough to meet Rust's worst-case effect density.

Moreover, the PCIe 4.0 x8 interface can transfer the required bandwidth for this engine, but an 8 GB buffer and the 128-bit bus limit the effective texture streaming . The on the tables: when you go from Low to High at 1080p, the average goes from 81 to 71, which is a modest drop of 10 FPS. Going to 4K, that GPU IO pressure topples the average from 51 to 29. So the GPU's role is entirely dominant after 1080p High.

Settings Recommendations

For a stable playable experience, the data points to 1080p Medium as the best balance. The 1080p Medium row shows 85 FPS average, a 72 FPS minimum, and a 97 FPS maximum. This keeps the game above 60 in all recorded dips, while the High stage (71 average) may still be o.file but with more texture quality. At 1440p, Medium gives 58 average, but the 49 FPS minimum means you will frequently see frame hesitates; Low at 1440p has an 87 average but the no recorded min. If you want good picture and faster list, 1440p Medium is the highest that still holds
