Rust

The AMD Ryzen 7 7800X3D paired with the NVIDIA GeForce RTX 4070 SUPER delivers a strong 1080p and 1440p experience in Rust, but the data shows that 4K Ultra is a stretch unless you are comfortable with frame rates in the low 40s. This combination ranks in the top tier of tested hardware, sitting at rank 248 out of 1717 combos, which places it in the 86th percentile of all configurations tested. The pairing leverages a high-end 8-core CPU with a 96 MB L3 cache and a 12 GB GPU that has enough bandwidth to handle Rust’s demanding draw distances, though the scaling curve reveals where each component takes over.

Resolution Scaling

The measured FPS data across resolutions shows a classic pattern of GPU-bound scaling, but with a twist at lower settings. At High settings, the average frame rate drops from 140.5 FPS at 1920x1080 to 98.5 FPS at 2560x1440, and then down to 56.5 FPS at 3840x2160. That is a 30% drop from 1080p to 1440p, and another 43% drop from 1440p to 4K. This steep decline indicates that the RTX 4070 SUPER is the limiting factor at higher resolutions, as the CPU’s 8 cores and 16 threads are more than sufficient to feed frames at lower pixel counts.

However, look at the Low settings curve. At 1080p Low, the system hits 220.4 FPS, which is a massive 57% jump over the High preset at the same resolution. At 1440p Low, it reaches 174 FPS, and even at 4K Low it manages 101.5 FPS. The fact that 4K Low is nearly double the frame rate of 4K High (101.5 vs 56.5 FPS) tells you that Rust’s High preset is loading the GPU heavily with effects and draw distances, while Low settings allow the CPU to push frame rates that are limited by the game engine’s single-threaded behavior. The CPU’s 5.00 GHz boost clock and 96 MB L3 cache are clearly doing heavy lifting at Low settings, where the GPU is not the bottleneck.

The scaling from Medium to Ultra is also revealing. At 1080p, Medium produces 167.6 FPS, High drops to 140.5 FPS, and Ultra falls to 110.6 FPS. At 4K, Medium yields 65.8 FPS, which is playable, but Ultra drops to 44.1 FPS, which is below the 60 FPS threshold most players target. The gap between Medium and Ultra at 4K is 33%, showing that Ultra settings carry a significant performance penalty that is not worth it for the visual gain in this title.

CPU Role

The Ryzen 7 7800X3D is a Zen 4 part on the AMD Socket AM5 platform, built on a 5 nm process. It has 8 cores and 16 threads, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. The standout feature is the 96 MB shared L3 cache, which is critical for Rust because the game’s procedural world generation and entity tracking are cache-sensitive. The CPU’s benchmark scores back this up: it scores 29149 in Cinebench R23 multi-core and 4115 in single-core, with a Passmark multi-thread score of 34293 and a single-thread score of 3759.

In the context of Rust, the CPU’s single-thread performance is more relevant than raw multi-core scores. The game’s simulation and physics tick on a limited number of threads, so the 7800X3D’s strong single-core result (959 in 3DMark single-thread) is what allows it to maintain high frame rates at 1080p Low (220.4 FPS) without the GPU being the limiter. The CPU’s 87th percentile ranking among all CPUs places it well above average, and its nearest rivals include the Intel Core i7-12700F (deltaPct 0.1) and the AMD Ryzen 9 5980HX (deltaPct 0.3). The 7800X3D is effectively tied with these parts in average benchmark score, but the 3D V-Cache gives it a specific advantage in Rust’s cache-heavy workloads that synthetic benchmarks do not fully capture.

The CPU’s 120 W TDP and dual-channel DDR5 memory support (83.2 GB/s bandwidth) means it will not starve the GPU for data, even at 1080p High where the frame rate reaches 140.5 FPS. The fact that the CPU maintains a 87% percentile rank against all CPUs while the GPU sits at 84% suggests that this combo is not CPU-limited in most scenarios, except at the very low settings where the engine’s single-thread limits are exposed.

GPU Role

The RTX 4070 SUPER is an Ada Lovelace part with 7168 shading units, 224 texture mapping units, and 80 ROPs. It runs at a base clock of 1980 MHz and boosts to 2475 MHz, with 12 GB of GDDR6X memory on a 192-bit bus delivering 504.2 GB/s of bandwidth. This memory bandwidth is crucial for Rust because the game streams in terrain and building entities continuously, and the 12 GB frame buffer is sufficient for 4K High without running out of VRAM, though the performance data suggests the GPU’s compute throughput is the limiting factor at that resolution.

The GPU’s benchmark scores show a Passmark G3D score of 29995 and a 3DMark Steel Nomad DX12 score of 4627. It ranks in the 84th percentile of all GPUs, with nearest rivals including the NVIDIA RTX A6000 (deltaPct -0.2) and the AMD Radeon RX 7650 GRE (deltaPct -0.3). This places it in professional-tier territory for compute, but for gaming, the 220 W TDP and dual-slot design suggest it is a mainstream high-end part. The GPU’s FP32 throughput of 35.48 TFLOPS is substantial, but Rust is not a compute-heavy title; it is more dependent on texture fill and memory bandwidth, which the 504.2 GB/s figure covers adequately.

At 1080p Ultra, the GPU pushes 110.6 FPS, which is a 21% drop from High (140.5 FPS). This drop is less severe than the 4K Ultra drop (44.1 FPS vs 56.5 FPS High), which is a 22% drop, but the absolute numbers are low enough at 4K that you will notice stutter. The GPU’s pixel rate of 198.0 GPixel/s and texture rate of 554.4 GTexel/s are high, but the data shows that the ray tracing cores and tensor cores (56 and 224 respectively) are not being utilized in Rust, which is a rasterized title. This means the GPU is working on raw fill rate, and the 44.1 FPS at 4K Ultra suggests the card is just not fast enough for maxed-out 4K in this game.

Measured FPS Breakdown

At 1920x1080, the combo delivers 220.4 FPS on Low, 167.6 FPS on Medium, 140.5 FPS on High, and 110.6 FPS on Ultra. The jump from Ultra to Low is a 99 FPS difference, which is a 89% improvement. This tells you that if you are chasing maximum refresh rates on a 240 Hz monitor, Low settings are the way to go, but High is still comfortably above 140 FPS.

At 2560x1440, the numbers are 174 FPS on Low, 115.5 FPS on Medium, 98.5 FPS on High, and 74.6 FPS on Ultra. The drop from 1080p to 1440p at each setting is roughly 20-25%, which is expected for a resolution increase of 78% more pixels. The 74.6 FPS at 1440p Ultra is still smooth on a 75 Hz monitor, but on a 144 Hz display you will want to drop to High to get close to 100 FPS.

At 3840x2160, the performance falls to 101.5 FPS on Low, 65.8 FPS on Medium, 56.5 FPS on High, and 44.1 FPS on Ultra. The 4K Low result is remarkable because it is higher than 1080p Ultra (101.5 vs 110.6 FPS), indicating that the CPU is still capable of pushing high frame rates if the GPU is given less work. However, the 4K Ultra result of 44.1 FPS is below the 45 FPS threshold that many players consider the minimum for a playable survival game, so you will need to compromise on settings if you are on a 4K display.

How This Combo Ranks

The combo’s rank of 248 out of 1717 tested combinations places it in the 86th percentile of all systems tested in Rust. This is a strong showing, but it is not in the top 10%, which is reserved for configurations with higher-end GPUs like the RTX 4080 or 4090. The CPU’s 87th percentile rank is slightly higher than the GPU’s 84th percentile, suggesting that the 7800X3D is slightly overqualified for the 4070 SUPER in this title, but the pairing is balanced enough to avoid significant bottlenecking.

In comparison to other combos, this setup is 0.1% faster than the average score of the Intel Core i7-12700F, which is a negligible difference. The GPU is 0.2% slower than the NVIDIA RTX A6000, which is a professional card with more memory but similar gaming performance. This means the 4070 SUPER is performing at the expected level for its class, and the 7800X3D is doing its job of keeping the frame rate high at lower resolutions. The data shows that this combo is well-matched for 1440p gaming, where it achieves 98.5 FPS on High, and is acceptable for 4K if you are willing to use Medium settings (65.8 FPS).
