# Rust: AMD Ryzen 5 5500 + AMD Radeon RX 6750 XT

This pairing of the AMD Ryzen 5 5500 and AMD Radeon RX 6750 XT delivers a mid-range experience in Rust, a survival title known for heavy procedural world simulation and frequent server-side updates. The measured frame rates reveal a system that is surprisingly balanced at lower resolutions but becomes clearly GPU-limited at 4K, with the CPU capable of pushing well over 170 FPS at 1080p Low yet the GPU capping Ultra settings at just 30 FPS in 4K. The data suggests this combo sits in the 1700th position out of 3723 tested combinations, placing it in the upper-middle tier of systems, with the Ryzen 5 5500's six Zen 3 cores providing ample thread headroom while the Radeon RX 6750 XT's 12 GB of VRAM becomes a decisive factor at higher resolutions and quality presets.

Resolution Scaling

The FPS drop from 1080p to 4K tells a clear story about which component becomes the bottleneck as pixel count rises. At Low settings, the average frame rate falls from 173 FPS at 1920x1080 to 119 FPS at 2560x1440, then further down to 70 FPS at 3840x2160. That represents a 31% reduction moving from 1080p to 1440p and a 41% additional drop from 1440p to 4K. This steep decline is classic GPU-bound behavior — the RX 6750 XT's rendering throughput, with its 13.31 TFLOPS FP32 compute and 432.0 GB/s memory bandwidth, simply cannot keep pace with the fourfold pixel increase from 1080p to 4K.

At Medium settings, the scaling pattern shifts slightly. The 1080p result of 116 FPS drops to 80 FPS at 1440p (a 31% decrease) and then to 47 FPS at 4K (a 41% decrease from 1440p). The consistency of these percentage drops across Low and Medium presets indicates that the GPU's fill rate and shading capacity are the limiting factors, rather than any memory bandwidth ceiling. The 12 GB GDDR6 frame buffer does not appear to be a constraint here — otherwise we would expect to see a more dramatic collapse at 4K when moving from Medium to High.

High settings show a similar trend but with a slightly steeper 4K penalty: 98 FPS at 1080p, 68 FPS at 1440p (31% drop), and 40 FPS at 4K (41% drop). Ultra settings compress the entire range, delivering 75 FPS at 1080p, 51 FPS at 1440p, and just 30 FPS at 4K. The 4K Ultra result of 30 FPS is exactly half the 1080p High figure, suggesting that the combination of Ultra quality settings and 4K resolution pushes the GPU's 166.4 GPixel/s pixel rate to its practical limit. For competitive play at high refresh rates, the 1080p Low result of 173 FPS demonstrates that the CPU can feed the GPU fast enough — the Ryzen 5 5500's 3.60 GHz base and 4.20 GHz boost clocks are sufficient to avoid becoming the primary constraint at lower resolutions.

CPU Role

The AMD Ryzen 5 5500 brings six cores and twelve threads based on the Zen 3 architecture, manufactured on TSMC's 7 nm process. Its benchmark profile shows a single-thread score of 836 in 3dmark and 2319 in Cinebench R23 single-core, with multi-thread results of 5411 in 3dmark max threads and 16429 in Cinebench R23 multicore. These numbers place the CPU at the 73rd percentile among all tested processors, with an average benchmark score of 19593. The nearest rivals include the AMD Ryzen AI 5 430 (deltaPct -0.1), Intel Core i5-12500 (deltaPct -0.4), Intel Core i7-10700F (deltaPct 0.5), and Intel Core i5-11600KF (deltaPct -0.7), indicating that the Ryzen 5 5500 sits within a tight performance cluster — less than a percentage point separates it from any of these competitors.

In Rust specifically, the CPU's role becomes evident when examining the FPS spread across quality settings at a fixed resolution. At 1080p, the difference between Low (173 FPS) and Ultra (75 FPS) is 98 FPS, a 57% reduction. This is a larger relative drop than what we see at 4K, where Low (70 FPS) to Ultra (30 FPS) is a 40 FPS or 57% reduction. The similar percentage drop at both resolutions suggests that the CPU's thread scheduling and cache behavior — with 16 MB of L3 cache and 512 KB L2 per core — are being exercised by Rust's simulation logic, which scales with the number of entities and building parts in the world.

The 12-thread count is particularly relevant for Rust, as the game's server-side tick rate and client-side rendering can spawn multiple worker threads. The Ryzen 5 5500's 3dmark 16-thread score of 5386 versus its 2-thread score of 1645 shows strong scaling from 2 to 8 threads (4593), with diminishing returns beyond that point. This pattern aligns with Rust's multi-threaded nature, where the first few threads handle rendering and physics, while additional threads manage network I/O and world updates. The 65 W TDP and dual-channel DDR4 memory support with 51.2 GB/s bandwidth provide adequate headroom for the game's streaming demands, though the 3dmark single-thread score of 836 indicates that per-core performance is not exceptional — explaining why the 1080p Low result of 173 FPS, while high, does not reach the 200+ FPS territory seen with faster single-thread CPUs.

FAQ

Q: Can this combo run Rust at 4K with playable frame rates?

A: At 4K Ultra, the average FPS is 30, which is borderline for playability. Dropping to 4K High yields 40 FPS, while 4K Medium delivers 47 FPS with a minimum of 40 FPS. For smoother 4K gameplay, the Low preset provides 70 FPS, making it the only 4K setting that comfortably exceeds 60 FPS.

Q: How does the CPU compare to its nearest rivals in synthetic benchmarks?

A: The Ryzen 5 5500 has an average benchmark score of 19593, placing it at the 73rd percentile. It is 0.1% behind the AMD Ryzen AI 5 430 (19617), 0.4% behind the Intel Core i5-12500 (19668), 0.5% ahead of the Intel Core i7-10700F (19499), and 0.7% behind the Intel Core i5-11600KF (19723). These deltas are negligible in real-world gaming.

Q: What is the best resolution for this combo to maintain 60+ FPS?

A: At 1080p, all settings except Ultra (75 FPS) exceed 60 FPS, with High at 98 FPS and Low at 173 FPS. At 1440p, Low (119 FPS) and High (68 FPS) both stay above 60 FPS, but Medium (80 FPS) also qualifies, while Ultra (51 FPS) falls short. At 4K, only Low (70 FPS) reaches the 60 FPS threshold.

Q: How much VRAM does the GPU have and does it matter for Rust?

A: The Radeon RX 6750 XT features 12 GB of GDDR6 memory on a 192-bit bus with 432.0 GB/s bandwidth. Given that 4K Ultra still runs at 30 FPS without stuttering (no minimum FPS data suggests frame drops), the 12 GB capacity appears sufficient for Rust's texture and asset loading at all tested settings.

Q: Is the GPU or CPU the limiting factor at 1080p Low?

A: The 1080p Low result of 173 FPS suggests the CPU is the primary constraint, as the GPU's 13.31 TFLOPS compute could theoretically drive higher frame rates at such low graphics load. The Ryzen 5 5500's 3dmark 2-thread score of 1645 and single-thread score of 836 indicate that per-core performance caps the frame rate in this scenario.

Q: How does this combo rank among all tested configurations?

A: The combo ranks 1700th out of 3723 tested combinations, placing it in the 54th percentile of all systems. This mid-pack position reflects the balanced nature of the CPU and GPU pairing, neither of which is a top-tier part but both of which perform competently in Rust.

Settings Recommendations

The measured FPS data provides clear guidance for optimizing the Rust experience. For 1080p displays, the High preset (98 FPS) offers the best balance between visual fidelity and smoothness — it is 15% slower than Low (173 FPS) but provides substantially better graphics quality, while still leaving headroom above the 60 FPS threshold. The Medium preset (116 FPS) is also viable, but High's additional visual detail costs only 18 FPS over Medium, making it the more compelling choice for most players.

At 1440p, the situation changes. The Low preset (119 FPS) is the only setting that provides a comfortable margin above 60 FPS, while High (68 FPS) and Medium (80 FPS) both remain playable but approach the 60 FPS boundary. The Ultra preset (51 FPS) dips below 60 FPS, which may be acceptable for slower-paced Rust gameplay but is not ideal for combat scenarios. For a 1440p monitor with a 60 Hz refresh rate, High is the recommended choice, as it delivers 68 FPS with a richer visual experience than Medium.

For 4K, the options are more constrained. The Low preset (70 FPS) is the only setting that maintains a 60+ FPS average, making it the default recommendation for 4K play. Medium (47 FPS) and High (40 FPS) are playable if the player prioritizes visuals over smoothness, but the 4K Ultra result of 30 FPS is below the threshold for comfortable gameplay in a fast-paced survival title. The measured minimum FPS at Medium 4K is 40, which suggests occasional drops below the average that could be noticeable in firefights.

How This Combo Ranks

The combo ranks 1700th out of 3723 tested combinations, placing it just above the median of all systems tested. This position is consistent with the component-level percentiles — the CPU sits at the 73rd percentile among all processors, while the GPU is at the 71st percentile among all graphics cards. The combination of two parts in the 71st-73rd percentile range yields a system that is neither a high-end outlier nor a budget compromise.

The ranking suggests that in Rust, this combo performs slightly worse than its component percentiles would indicate. This could be due to Rust's sensitivity to single-thread performance (the CPU's 3dmark single-thread score is 836) or the game's draw call overhead, which the RX 6750 XT's RDNA 2.0 architecture handles reasonably well but not exceptionally. The nearest GPU rivals — the AMD Radeon R9 M395X (deltaPct 0.5), AMD FirePro W7100 (deltaPct 0.6), AMD FirePro D700 (deltaPct 0.7), and NVIDIA GeForce RTX 3080 Ti Mobile (deltaPct 1.1) — are all within 1.1% of the RX 6750 XT's average benchmark score of 26011, indicating that the GPU's raw compute is competitive with a wide range of parts.

The rank of 1700 out of 3723 means there are 2023 combos that perform worse and 1699 that perform better. This places the system in the upper half, but not by a wide margin. For Rust specifically, the data shows that the combo can handle 1440p High at 68 FPS, which is a solid experience, but it cannot push 4K Ultra past 30 FPS, which limits its appeal for players with high-resolution displays who demand maximum quality settings.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce an average of 173 FPS, while Medium yields 116 FPS with a minimum of 99 and maximum of 134. High settings drop to 98 FPS, and Ultra falls to 75 FPS. The range from 75 to 173 FPS across four presets demonstrates the GPU's scaling efficiency — each step up in quality costs roughly 20-30% of the previous frame rate.

At 2560x1440, the averages compress to a narrower band. Low settings give 119 FPS, Medium provides 80 FPS with a minimum of 68 and maximum of 92, High delivers 68 FPS, and Ultra produces 51 FPS. The gap between Low and Ultra is 68 FPS, compared to 98 FPS at 1080p, indicating that the GPU's pixel processing becomes more dominant at higher resolution. The minimum FPS at Medium (68) matches the High average, suggesting that Medium's variance is moderate.

At 3840x2160, the results show a clear GPU bottleneck. Low settings average 70 FPS, Medium averages 47 FPS with a minimum of 40 and maximum of 54, High averages 40 FPS, and Ultra averages 30 FPS. The progression from 70 to 47 to 40 to 30 shows diminishing returns as quality increases — the gap between Medium and High is only 7 FPS, while the gap between Low and Medium is 23 FPS. This non-linear scaling suggests that certain quality settings (perhaps shadows or post-processing) have a disproportionate impact on the GPU's 166.4 GPixel/s pixel rate.

GPU Role

The AMD Radeon RX 6750 XT, based on the Navi 22 chip with RDNA 2.0 architecture, is the dominant factor in determining Rust's performance at higher resolutions. Its 12 GB of GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth, which is ample for Rust's texture streaming and asset loading. The GPU's boost clock of 2600 MHz and game clock of 2495 MHz, combined with 2560 shading units and 160 TMUs, deliver a measured texture rate of 416.0 GTexel/s and a pixel rate of 166.4 GPixel/s.

In synthetic benchmarks, the GPU scores 20700 in Passmark G3D and 137249 in Geekbench Metal, with a Vulkan score of 98089. Its average benchmark score of 26011 places it at the 71st percentile among all GPUs. The nearest rivals are all within 1.1% of this score, including the AMD Radeon R9 M395X (0.5%), AMD FirePro W7100 (0.6%), AMD FirePro D700 (0.7%), and NVIDIA GeForce RTX 3080 Ti Mobile (1.1%). This tight clustering suggests that the RX 6750 XT's performance is well understood and consistent across different benchmark suites.

The GPU's role in Rust becomes most apparent at 4K, where the 30 FPS Ultra result highlights the limits of its 13.31 TFLOPS FP32 compute. The 12 GB VRAM capacity is not the limiting factor — if it were, we would expect to see frame stuttering or texture pop-in at 4K Ultra, but the measured data shows no minimum FPS values for Ultra settings, indicating stable frame delivery. Instead, the 166.4 GPixel/s pixel rate is the constraint, as 4K resolution requires 8.3 million pixels per frame, and Ultra settings add expensive shading and post-processing passes that consume the GPU's shading units and TMUs. The 40 RT cores are unlikely to be utilized in Rust (which does not feature ray tracing), so their presence does not influence these results.
