Rust

Rust is a demanding survival title that punishes both CPU and GPU heavily, and this pairing of an AMD Ryzen 5 4600G with an AMD Radeon RX 5700 XT lands in the lower-mid portion of tested combinations. The combo ranks 2769 out of 3723 tested combos, meaning roughly 74% of tested systems perform better in this game. That placement is not a surprise given the hardware generation gap, but the measured FPS data shows this setup remains playable at 1080p with adjusted settings, while 4K pushes the GPU past its comfort zone.

FAQ

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

A: The data shows 1920x1080 is the only resolution where the combo consistently hits playable frame rates. At 1080p Low, the average FPS is 135, dropping to 90 at Medium, 76 at High, and 58 at Ultra. At 2560x1440, even Low settings only produce 93 FPS average, and at 3840x2160, no setting reaches 60 FPS average.

Q: How does the RX 5700 XT perform at 4K in Rust?

A: At 3840x2160, the measured results are poor across all settings. Low settings produce 55 FPS average, Medium drops to 37 FPS (with a minimum of 31 and maximum of 42), High falls to 31 FPS, and Ultra averages just 24 FPS. The 8 GB VRAM and 448.0 GB/s bandwidth are insufficient for smooth 4K gameplay in this title.

Q: Does the Ryzen 5 4600G bottleneck the RX 5700 XT?

A: Benchmark data suggests the CPU is not the primary limiter at higher resolutions. The 4600G has 6 cores and 12 threads with a boost clock of 4.20 GHz, and its Cinebench R23 multicore score of 13593 is respectable. However, at 1080p Low where the GPU has less work, the CPU may start to matter more, but the 135 FPS average indicates it handles the load adequately.

Q: What settings should I use for competitive play?

A: For the smoothest experience, 1080p Low gives 135 FPS average, which is the highest measured result for this combo. If you prefer better visuals, 1080p Medium still provides 90 FPS average with a minimum of 77 FPS, which remains fluid for most play styles. Ultra settings at 1080p drop to 58 FPS, which is borderline for fast-paced combat.

Q: How does this combo compare to similar hardware in the database?

A: The CPU sits at the 71st percentile among all CPUs, with an average benchmark score of 17507. Its nearest rivals include the AMD Ryzen 3 PRO 5355GE (0.1% faster) and Intel Core 7 150U (0.6% faster). The GPU is at the 59th percentile among all GPUs with an average score of 16361, sitting close to the AMD Radeon Pro 5600M (0.1% faster) and NVIDIA RTX PRO 6000 Blackwell (0.3% faster).

Q: Is the 8 GB VRAM enough for Rust at high settings?

A: At 1080p and 1440p, the 8 GB GDDR6 memory appears sufficient based on the FPS results. However, at 4K Ultra the average FPS collapses to 24, suggesting VRAM capacity or bandwidth becomes a limiting factor. The RX 5700 XT's 448.0 GB/s memory bandwidth is the same across all resolutions, so the 4K drop is more likely due to raw compute limits.

How This Combo Ranks

The combo's rank of 2769 out of 3723 tested combinations places it in the lower third of all systems tested for Rust. This is a meaningful data point because Rust is known to be sensitive to both CPU single-thread performance and GPU rasterization power. The Ryzen 5 4600G, despite being a capable 6-core / 12-thread processor from the 4000 series, has a single-thread 3DMark score of 726 and a Cinebench R23 single-core score of 1919, which are modest by modern standards. The RX 5700 XT, while a solid 1440p card from the RDNA 1.0 era, trails newer architectures significantly.

Looking at the deltaPct values for the CPU, the 4600G's average benchmark score of 17507 is essentially tied with its nearest rivals. The AMD Ryzen 3 PRO 5355GE scores 17482 (0.1% slower), while the Intel Core i3-14100T scores 17648 (0.8% faster). This means the 4600G is not a bottleneck in synthetic tests relative to its peers, but those peers are themselves mid-range parts. The GPU's nearest rival data shows a similar picture: the RX 5700 XT's score of 16361 is 0.1% below the AMD Radeon Pro 5600M and 0.9% below the NVIDIA GeForce RTX 5090 D V2, which is an extreme outlier comparison due to the database's ranking algorithm.

What this rank tells a builder is that the pairing is balanced in the sense that neither component wildly outperforms the other, but both are dated. The combo rank reflects that Rust's optimization favors newer CPUs with higher IPC and GPUs with more raw throughput. For a system targeting 1080p at medium-to-high settings, this rank is acceptable because the measured FPS supports that use case. For 1440p or 4K, the rank correctly predicts a struggle.

GPU Role

The AMD Radeon RX 5700 XT is built on the Navi 10 chip using RDNA 1.0 architecture on a 7 nm process. It has 2560 shading units, 160 texture mapping units, and 64 render output units. The GPU's base clock is 1605 MHz, with a game clock of 1755 MHz and a boost clock of 1905 MHz. Memory runs at 1750 MHz (14 Gbps effective) across an 8 GB GDDR6 interface with a 256-bit bus, yielding 448.0 GB/s of bandwidth.

In Rust, the GPU's role is significant but not exclusive. At 1080p, the FPS scales clearly with settings: 135 at Low, 90 at Medium, 76 at High, and 58 at Ultra. This 77 FPS spread between Low and Ultra demonstrates that the RX 5700 XT has enough compute headroom to render Rust at high frame rates when pixel count is low, but the gap narrows as settings increase. The 8 GB VRAM is sufficient for 1080p and 1440p, as evidenced by playable results at those resolutions.

At 1440p, the GPU starts to show strain. Low settings yield 93 FPS, Medium drops to 62 FPS (min 53, max 71), High gives 52 FPS, and Ultra falls to 40 FPS. The 41 FPS drop from Low to Ultra at 1440p indicates that the GPU's shading units and memory bandwidth are being saturated. At 4K, the situation worsens dramatically: Low gives 55 FPS, Medium 37 FPS (min 31, max 42), High 31 FPS, and Ultra 24 FPS. The difference between 1080p Low (135 FPS) and 4K Low (55 FPS) is an 80 FPS loss, which is a direct consequence of the GPU being forced to render 4 times the pixels.

The GPU's percentile ranking of 59 among all GPUs places it just above average, but its nearest rival comparisons show it is within 1% of several professional and workstation cards. The passmark G3D score of 16277 and 3DMark Steel Nomad score of 2134 reflect a mid-range rasterization performer. For Rust specifically, the GPU's 9.754 TFLOPS FP32 compute is the key number, as Rust's rendering relies heavily on traditional pixel shading rather than ray tracing or AI acceleration, neither of which this GPU supports.

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 135 FPS, Medium averages 90 FPS with a minimum of 77 and maximum of 104, High averages 76 FPS, and Ultra averages 58 FPS. This shows that 1080p is the sweet spot for this combo, with even Ultra settings remaining technically playable.

Moving to 2560x1440, the numbers tell a different story. Low settings average 93 FPS, which is still smooth, but Medium drops to 62 FPS (min 53, max 71), High falls to 52 FPS, and Ultra averages just 40 FPS. The minimum FPS of 53 at Medium suggests frame pacing issues during intense scenes, which could be problematic in Rust's PvP encounters where sudden player models load in.

At 3840x2160, the combo is clearly out of its depth. Low averages 55 FPS, which is borderline playable but not competitive. Medium averages 37 FPS with a minimum of 31 and maximum of 42, indicating significant frame time variance. High averages 31 FPS, and Ultra drops to 24 FPS. None of these 4K results would be acceptable for a game where quick reaction times matter.

Comparing the settings scaling at each resolution, the pattern is consistent but the magnitude differs. At 1080p, moving from Low to Ultra costs 77 FPS (135 to 58). At 1440p, the same settings change costs 53 FPS (93 to 40). At 4K, it costs 31 FPS (55 to 24). This shows that as resolution increases, the absolute FPS loss from raising settings shrinks because the GPU is already bottlenecked by pixel fill rate.

The Medium preset data with min/max FPS is particularly useful. At 1080p Medium, the 77 FPS minimum and 104 FPS maximum show a 27 FPS range, which is acceptable. At 1440p Medium, the 53-71 FPS range is tighter but the lower average makes dips more noticeable. At 4K Medium, the 31-42 FPS range with a 37 average means the experience will feel stuttery during busy moments.

Resolution Scaling

The FPS drop from 1080p to 4K reveals where the bottleneck lies. At Low settings, 1080p produces 135 FPS, 1440p produces 93 FPS, and 4K produces 55 FPS. The scaling from 1080p to 1440p is a 31% reduction in FPS, while from 1440p to 4K it's a 41% reduction. This non-linear scaling is typical of a GPU-bound scenario, where the pixel count increase from 2.07 million (1080p) to 8.29 million (4K) overwhelms the RX 5700 XT's 64 ROPs and 448.0 GB/s bandwidth.

At Ultra settings, the pattern is similar but with lower absolute values: 58 FPS at 1080p, 40 FPS at 1440p, and 24 FPS at 4K. The percentage drops are 31% and 40% respectively, nearly identical to Low settings. This consistency suggests that the GPU's compute units are the limiting factor, not the settings preset, because the relative performance degradation is the same regardless of quality level.

Comparing Medium settings, which have min/max data: 1080p Medium runs at 90 FPS average (77-104), 1440p at 62 FPS (53-71), and 4K at 37 FPS (31-42). The minimum FPS scales similarly to the average, indicating that frame pacing remains stable across resolutions, just at lower absolute levels. The maximum FPS at 4K Medium (42) is barely above the minimum at 1080p High (58), showing how quickly the GPU runs out of headroom.

This scaling data points to the GPU as the primary limiting component. If the CPU were the bottleneck, we'd expect to see less FPS difference between 1080p and 1440p because the CPU workload doesn't change with resolution. Instead, the linear relationship between pixel count and FPS loss (approximately 30-40% per resolution step) confirms the RX 5700 XT is doing all the heavy lifting, and it's simply not enough for 4K in Rust.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on Zen 2 architecture (codename Renoir) built on a 7 nm process. It has a base clock of 3.70 GHz and a boost clock of 4.20 GHz, with a 65 W TDP. The cache hierarchy includes 64 KB L1 per core, 512 KB L2 per core, and 8 MB shared L3 cache. Memory support is DDR4 with dual-channel configuration and 51.2 GB/s bandwidth. Its integrated Radeon Vega 7 graphics are not used in this pairing, but the CPU's single-thread performance matters for Rust.

In synthetic benchmarks, the 4600G scores 726 in 3DMark single-thread, 805 in Cinebench R20 single-core, and 1919 in Cinebench R23 single-core. These scores place it at the 71st percentile among all CPUs, with an average benchmark score of 17507. The nearest rival data shows the 4600G is within 1% of several other processors, including the AMD Ryzen 3 PRO 5355GE (0.1% faster) and Intel Core 7 150U (0.6% faster), meaning it's not an outlier in either direction.

Rust is known to be CPU-intensive during world loading and entity updates, but the measured FPS data suggests the 4600G handles this adequately. At 1080p Low, the combo achieves 135 FPS average, which is a strong result for any CPU. The fact that 1080p Ultra still maintains 58 FPS indicates the CPU can feed the GPU enough frames even with higher graphical loads. However, the CPU's 8 MB L3 cache is modest by modern standards, and the passmark physics score of 676 reflects average physics computation performance.

Comparing the CPU's benchmark results to its role in Rust, the 3DMark 16-thread score of 4863 and max-thread score of 4889 show it scales well across cores, but Rust typically doesn't utilize 12 threads efficiently. The single-thread score of 726 is more relevant, and it's clear the 4600G doesn't match newer CPUs in this metric. Yet the measured FPS at 1080p doesn't reveal a catastrophic bottleneck, suggesting that at this resolution with this GPU, the CPU keeps pace.

The CPU's memory bandwidth of 51.2 GB/s is another factor. Rust loads large textures and map data, and the dual-channel DDR4 configuration provides adequate bandwidth for 1080p gaming. At 4K, the CPU becomes even less relevant because the GPU is so heavily bottlenecked that CPU performance doesn't matter. The data supports this: 4K Low (55 FPS) vs 4K Ultra (24 FPS) shows only a 31 FPS difference, which is entirely GPU-driven, not CPU-driven.

For builders considering this CPU, the 4600G's 65 W TDP and AM4 socket compatibility make it an easy drop-in for existing systems. Its 7 nm process keeps thermals manageable, though the data doesn't include thermal measurements. The CPU's 12 threads provide headroom for background tasks like Discord or streaming, and the 4.20 GHz boost clock ensures responsive gameplay in less demanding titles. In Rust specifically, this CPU is sufficient to avoid being the primary frame rate limiter at 1080p, which is the resolution where this combo is most viable.
