Rust

The AMD Ryzen 7 7800X3D and NVIDIA GeForce RTX 4070 combination delivers a highly capable Rust experience, with performance scaling that clearly illustrates the shift from CPU-bound to GPU-bound behavior as resolution increases. The data shows a 129.2 average FPS at 1080p High, which drops to 88.2 at 1440p and further to 49.5 at 4K. This represents a 31.7% performance loss when moving from 1080p to 1440p, and a 61.7% loss from 1080p to 4K. The frame rate trajectory across resolutions suggests that at 1080p, the processor’s large 96 MB L3 cache is effectively feeding the graphics card, while at 4K the GPU’s rendering workload becomes the dominant constraint.

Resolution Scaling

The resolution scaling pattern in Rust reveals a system that is well-balanced at lower resolutions but progressively GPU-limited at higher ones. At 1080p Low, the combo produces 222.8 FPS, which is an exceptionally high figure indicating that the CPU and its 3D V-Cache are not the limiting factor at this setting. Moving to 1440p Low drops performance to 154.9 FPS, a 30.5% reduction that still leaves ample headroom for high-refresh-rate monitors. At 4K Low, the average falls to 91.3 FPS, demonstrating that even with minimal graphical load, the RTX 4070’s rendering capabilities begin to cap performance.

The scaling behavior changes notably when comparing settings within a resolution. At 1080p, the gap between Low and Ultra is 125.4 FPS (222.8 vs. 97.4), showing that the GPU has significant spare capacity at this resolution. At 1440p, the Low-to-Ultra spread narrows to 86.9 FPS (154.9 vs. 68.0), indicating the GPU is working harder. At 4K, the spread compresses to 50.1 FPS (91.3 vs. 41.2), which strongly suggests that the graphics card is the primary bottleneck at this resolution. The data indicates that users targeting 4K should expect the RTX 4070 to be the determining factor, while 1080p users will benefit directly from the CPU’s strong single-thread and cache performance.

How This Combo Ranks

In the comprehensive benchmark database, this specific CPU-GPU pairing ranks 360th out of 1717 tested combinations for Rust, placing it in the top 21% of all systems evaluated. This rank reflects a strong overall capability, though it is not among the elite configurations at the very top of the list. The ranking suggests that while this combo handles Rust well, there are many other pairings that achieve higher average frame rates in this title.

The CPU’s individual benchmark scores contextualize its contribution to this ranking. The Ryzen 7 7800X3D scores 29149 in Cinebench R23 multi-core and 4115 in single-core, with an average benchmark score of 31580 across all tests. This places it in the 87th percentile of all CPUs, with nearest rivals including the Intel Core i7-12700F (0.1% faster), AMD Ryzen 9 5980HX (0.3% slower), and AMD Ryzen 7 8700G (0.6% slower). The GPU’s average benchmark score is 37283, placing it in the 81st percentile of all GPUs. The combination’s overall rank of 360 indicates that Rust benefits from the CPU’s strengths, but the GPU’s mid-tier positioning in the database prevents a higher overall placement.

GPU Role

The NVIDIA GeForce RTX 4070 brings 12 GB of GDDR6X memory on a 192-bit bus, yielding 504.2 GB/s of memory bandwidth. Its boost clock of 2475 MHz and base clock of 1920 MHz support a pixel rate of 158.4 GPixel/s and a texture rate of 455.4 GTexel/s. The 5888 shading units and 184 tensor cores provide the computational foundation for the observed frame rates. The GPU’s 12 GB VRAM capacity is sufficient for Rust’s demands at the tested resolutions, as evidenced by the consistent performance scaling without any anomalous frame drops that would indicate memory capacity issues.

The GPU’s FP32 performance of 29.15 TFLOPS directly influences the 4K results, where the rendering load is highest. At 4K Ultra, the combo produces 41.2 FPS, which is the lowest measured figure in the dataset. This represents a 57.7% drop from the 1080p Ultra result of 97.4 FPS. The GPU’s average benchmark score of 37283 places it near the AMD Radeon RX Vega 56 (0.6% slower) and NVIDIA GeForce RTX 4080 Mobile (2.2% faster), indicating that its raw compute power is competitive with those parts. The 200 W TDP and 550 W suggested PSU indicate a power profile that is manageable for most mid-range builds.

Measured FPS Breakdown

At 1920x1080, the performance hierarchy is clear across settings. Low settings yield 222.8 FPS, Medium produces 153.8 FPS, High achieves 129.2 FPS, and Ultra drops to 97.4 FPS. The step from Low to Medium represents a 31% reduction, while the step from High to Ultra costs an additional 24.6%. These figures indicate that even at Ultra settings, the 1080p experience remains well above the 60 FPS threshold, making this resolution entirely comfortable for this hardware.

Moving to 2560x1440, the results show 154.9 FPS at Low, 105 FPS at Medium, 88.2 FPS at High, and 68 FPS at Ultra. The 1440p Ultra result of 68 FPS is still playable, but the margin above 60 FPS is slim. The data shows that 1440p Medium offers a 54.4% improvement over Ultra, suggesting that users seeking higher refresh rates should consider Medium settings at this resolution.

At 3840x2160, the performance envelope tightens considerably. Low settings produce 91.3 FPS, Medium delivers 61.5 FPS, High manages 49.5 FPS, and Ultra falls to 41.2 FPS. The 4K results indicate that only Low and Medium settings provide frame rates at or above the 60 FPS target. The 4K High result falls below 60 FPS, and Ultra dips into the low 40s, which would be noticeable in fast-paced gameplay. The scaling from 1080p to 4K at High settings (129.2 to 49.5 FPS) represents a 61.7% reduction, highlighting the GPU’s central role at higher resolutions.

Settings Recommendations

For 1080p users, the data supports using Ultra settings, as the 97.4 FPS average remains well above playable thresholds. The step from High to Ultra costs 24.6% performance, but the absolute frame rate is still high enough for a responsive experience. Users with 144Hz monitors will find that High settings (129.2 FPS) approach the refresh rate, while Medium (153.8 FPS) exceeds it.

At 1440p, the recommendation depends on the target refresh rate. For 60 FPS gaming, Ultra settings at 68 FPS are viable. For 144Hz displays, Medium settings at 105 FPS provide a better experience, while Low at 154.9 FPS fully saturates a 144Hz panel. The data indicates that High settings at 88.2 FPS represent a reasonable middle ground for most users.

For 4K, the measured results clearly show that Medium settings at 61.5 FPS are the highest quality option that maintains 60 FPS. Low settings at 91.3 FPS offer significant headroom and are recommended for competitive play. High and Ultra settings fall below 50 FPS and should be avoided unless visual fidelity is the absolute priority over frame rate. The 41.2 FPS Ultra result is the only configuration that drops below 45 FPS, making it the least recommended option across all tested scenarios.
