Rust

The AMD Ryzen 5 5600GT and NVIDIA GeForce RTX 5090 D combination ranks 126th out of 2953 tested combos for Rust, placing it in the top 5% of all configurations. This is an exceptionally strong pairing for the game, though the ranking reveals an interesting dynamic: the GPU is dramatically more powerful than the CPU, and the benchmark results reflect that bottleneck clearly. The combo’s percentile placement is driven almost entirely by the GPU’s raw rendering power, while the CPU’s 74th percentile standing among all processors acts as a limiting factor in lower-resolution scenarios. The data indicates that this is a system where frame rates are high across the board, but the scaling pattern shows the CPU holding back the GPU’s full potential at 1080p and 1440p.

How This Combo Ranks

The combo’s 126th rank out of 2953 tested configurations is a strong showing, placing it ahead of roughly 96% of all tested pairings for Rust. This rank reflects the GPU’s dominance in the pairing, as the RTX 5090 D sits in the 92nd percentile among all GPUs, while the CPU sits in the 74th percentile. The gap between these two percentiles explains why the combo does not rank higher: the CPU is the weaker link, and it prevents the system from achieving the top-tier frame rates that the GPU alone could deliver.

The GPU’s average benchmark score of 77712 is nearly four times the CPU’s average of 20733, making it clear which component drives performance in this game. The nearest GPU rivals in the database—the AMD Radeon RX 6650M XT at 76904 (1.1% ahead), the AMD Radeon RX 6850M XT at 78940 (1.6% behind), and the NVIDIA Tesla P100 PCIe variants at 79396 and 79605 (2.1% and 2.4% behind)—show that the RTX 5090 D is competitive but not the absolute fastest in the database. The CPU’s nearest rivals, including the Intel Core i5-12490F at 20802 (-0.3%), the Intel Xeon 6325P at 20821 (-0.4%), and the Intel Core Ultra 5 125U at 20826 (-0.4%), show that the 5600GT is essentially tied with mid-range competitors, reinforcing its role as a mid-tier processor paired with a top-tier GPU.

GPU Role

The RTX 5090 D is the clear performance leader in this combo, and its specifications explain why it dominates Rust’s benchmarks. The GPU features 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of bandwidth. This massive memory allocation is far more than Rust requires, meaning VRAM capacity is never a limiting factor at any resolution or setting. The GPU’s base clock of 2017 MHz and boost clock of 2407 MHz, combined with 21760 shading units, deliver raw compute power that easily handles Rust’s rendering demands.

The GPU’s benchmark scores confirm its strength: a PassMark G3D score of 44065, a Geekbench Vulkan score of 376915, and a 3DMark Steel Nomad DX12 score of 14326. These numbers place the GPU in the 92nd percentile, and the measured FPS in Rust reflects this. At 4K Ultra, the combo still manages 61 FPS, which is playable, and at 4K Low, it jumps to 141 FPS. The GPU’s 104.8 TFLOPS of FP32 compute and 1,636.8 GTexel/s texture rate ensure that even the most demanding settings are handled with ease. The GPU’s 176 ROPs and 680 TMUs provide ample pixel and texture throughput for Rust’s environments.

The nearest GPU rivals are all notably less powerful in terms of memory bandwidth and compute, yet the RTX 5090 D only leads them by 1.1% to 2.4% in average benchmark score. This suggests that the database’s average benchmark scores may not fully capture the GPU’s advantage in real-world gaming scenarios like Rust, where memory bandwidth and raw shader throughput matter more than synthetic compute tests. The GPU’s 32 GB VRAM, in particular, is a massive asset for Rust’s large, persistent world, allowing for high-resolution textures without any stutter or pop-in.

Resolution Scaling

The measured FPS data shows a clear pattern of diminishing returns as resolution increases, with the CPU becoming more of a bottleneck at lower resolutions. At 1080p Low, the combo achieves 196 FPS, but at 4K Low, it drops to 141 FPS—a 28% decrease. At 1080p High, the combo hits 159 FPS, while at 4K High, it drops to 80 FPS—a 50% decrease. This scaling pattern is typical for a system where the GPU is overkill for the CPU: at 1080p, the CPU limits performance, and the GPU has headroom to spare; at 4K, the GPU becomes the primary bottleneck, but the CPU still holds it back from reaching its full potential.

The Medium settings data provides the most complete picture, with min/max FPS values. At 1080p Medium, the combo averages 169 FPS with a min of 143 and max of 194. At 1440p Medium, it averages 149 FPS with a min of 127 and max of 171. At 4K Medium, it averages 95 FPS with a min of 81 and max of 109. The drop from 1080p to 1440p is 12%, and from 1440p to 4K is 36%. This steep drop at 4K indicates that the GPU is being pushed harder, but the CPU’s limitations are still present, preventing the GPU from fully stretching its legs.

The Ultra settings data shows the most dramatic scaling. At 1080p Ultra, the combo averages 144 FPS; at 1440p Ultra, it drops to 103 FPS (a 28% decrease); and at 4K Ultra, it falls to 61 FPS (a 41% decrease from 1440p). The fact that 1080p Ultra achieves only 144 FPS, while 1080p Low achieves 196 FPS, suggests that the CPU is the limiting factor even at Ultra settings—the GPU is capable of far more than 144 FPS, but the CPU cannot feed it fast enough. The 4K Ultra result of 61 FPS is the only point where the GPU is clearly the bottleneck, as the CPU has enough headroom to keep up with the GPU’s reduced frame rate.

FAQ

Q: Is this combo better suited for high-resolution or high-refresh-rate gaming in Rust?

A: The data shows the combo is strong at both, but it excels more at high refresh rates. At 1080p Medium, it averages 169 FPS, and at 1440p Medium, it averages 149 FPS, both suitable for high-refresh monitors. At 4K Medium, it drops to 95 FPS, which is still playable but not competitive for high-refresh gaming. The 4K Ultra result of 61 FPS suggests the GPU is the limiting factor at that point.

Q: How much of a performance drop occurs when moving from 1080p to 4K?

A: The drop varies by settings. At Low settings, the drop from 1080p to 4K is 55 FPS (from 196 to 141), a 28% decrease. At High settings, the drop is 79 FPS (from 159 to 80), a 50% decrease. At Ultra settings, the drop is 83 FPS (from 144 to 61), a 58% decrease. The larger percentage drops at higher settings indicate the GPU is being pushed harder.

Q: What is the best setting for 4K gaming with this combo?

A: At 4K, the Medium setting provides 95 FPS, which is the best balance of quality and performance. Low settings offer 141 FPS but sacrifice visual quality, while High drops to 80 FPS and Ultra to 61 FPS. The Medium setting’s min FPS of 81 and max of 109 show it is stable enough for smooth gameplay.

Q: Does the CPU bottleneck the GPU in Rust?

A: Yes, the data suggests the CPU is the limiting factor at lower resolutions. At 1080p Low, the combo achieves 196 FPS, but the GPU is capable of far more, as evidenced by its 92nd percentile ranking. The CPU’s 74th percentile and its average benchmark score of 20733, compared to the GPU’s 77712, indicate the CPU cannot keep up with the GPU’s frame-generation capacity.

Q: How does this combo compare to the GPU’s nearest rivals in the database?

A: The RTX 5090 D is only 1.1% ahead of the AMD Radeon RX 6650M XT, 1.6% behind the AMD Radeon RX 6850M XT, and 2.1-2.4% behind the NVIDIA Tesla P100 PCIe variants in average benchmark score. Despite this, the RTX 5090 D’s 32 GB VRAM and 1.79 TB/s bandwidth provide a significant real-world advantage in Rust’s large-world rendering.

Q: What is the CPU’s role in the combo’s ranking?

A: The CPU is the weaker component, ranking in the 74th percentile, while the GPU ranks in the 92nd. The CPU’s nearest rivals are all within 0.5% of its average score, showing it is a mid-range processor. The CPU’s 6 cores and 12 threads, with a boost clock of 4.60 GHz, are sufficient for Rust, but they limit the GPU at lower resolutions.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo’s performance across resolutions and settings. At 1080p, the combo ranges from 144 FPS at Ultra to 196 FPS at Low. The Medium setting averages 169 FPS with a min of 143 and max of 194, while High averages 159 FPS. This shows that the combo is capable of high refresh rates at the most common resolution, with even Ultra settings staying above 144 FPS.

At 1440p, the combo ranges from 103 FPS at Ultra to 173 FPS at Low. The Medium setting averages 149 FPS with a min of 127 and max of 171, while High averages 136 FPS. The drop from 1080p to 1440p is consistent across settings, averaging around 15-20%, which is expected for a resolution increase. The 1440p results are still excellent for high-refresh monitors, with even Ultra staying above 100 FPS.

At 4K, the combo ranges from 61 FPS at Ultra to 141 FPS at Low. The Medium setting averages 95 FPS with a min of 81 and max of 109, while High averages 80 FPS. The 4K results show the combo is playable at all settings, but only Low and Medium settings achieve frame rates above 100 FPS. The Ultra setting at 61 FPS is the only point where the combo falls below 60 FPS, and it is still technically playable.

The Medium settings provide the only complete min/max data, allowing for an analysis of frame time stability. At 1080p Medium, the min of 143 and max of 194 show a 51 FPS spread, indicating some variance but generally stable performance. At 1440p Medium, the min of 127 and max of 171 show a 44 FPS spread, slightly tighter. At 4K Medium, the min of 81 and max of 109 show a 28 FPS spread, which is the tightest of the three resolutions, suggesting more consistent frame times at higher resolutions where the GPU is more evenly loaded.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on the Zen 3 architecture, running on the AMD Socket AM4 platform. It has a base clock of 3.60 GHz and a boost clock of 4.60 GHz, with a 65 W TDP. The CPU’s 16 MB of L3 cache and 51.2 GB/s memory bandwidth are modest by modern standards, but they are sufficient for Rust’s server-side and world-generation tasks. The CPU’s benchmarks show it is a solid mid-range performer: a Cinebench R23 multicore score of 17272, a Geekbench multicore score of 7986, and a PassMark multithread score of 20325.

The CPU’s percentile ranking of 74th places it ahead of most processors, but its nearest rivals are all within 0.5% of its average score of 20733. The Intel Core i5-12490F, Intel Xeon 6325P, Intel Core Ultra 5 125U, and AMD EPYC 7J13 all score between 20802 and 20845, showing that the 5600GT is essentially tied with these competing parts. This means the CPU is not a standout performer, but it is also not a weak link in most games.

In Rust, the CPU’s role is primarily to handle the game’s simulation and physics, which are single-threaded to a degree. The CPU’s single-thread performance, as measured by a PassMark single-thread score of 3348 and a Cinebench R23 single-core score of 2438, is adequate but not exceptional. The data shows that at 1080p, the CPU limits the GPU, as evidenced by the fact that the combo achieves only 196 FPS at Low settings, while the GPU could likely push much higher frame rates. The CPU’s boost clock of 4.60 GHz helps, but the 6-core/12-thread configuration is not enough to fully saturate the RTX 5090 D’s rendering pipeline.

The CPU’s 3DMark scores provide additional context: a single-thread score of 913, a 2-thread score of 1794, a 4-thread score of 3446, an 8-thread score of 4968, and a 16-thread score of 5523. These scores show that scaling from 2 to 4 threads is strong (a 92% increase), but scaling from 8 to 16 threads is weak (an 11% increase), indicating that the CPU’s 6 cores are fully utilized but additional threads do not help much. This is consistent with Rust’s reliance on a few heavily-threaded tasks, and it explains why the CPU becomes a bottleneck at lower resolutions where the GPU is waiting for data.
