Rust

Rust is a demanding survival title, and the data for the Intel Core i7-14700F paired with the NVIDIA GeForce RTX 3080 Ti shows a configuration that scales predictably with resolution and settings, but with some interesting shifts in bottleneck behavior. At 1080p, the combo delivers high frame rates that suggest a strong CPU contribution, while at 4K, the GPU becomes the clear limiting factor. The measured results provide a clear picture of how this pairing handles Rust’s specific rendering loads across the three primary resolutions.

Resolution Scaling

The transition from 1080p to 4K reveals a significant drop in performance, which is expected given the increased pixel count. At 1080p with Low settings, the system achieves an average of 224.7 FPS, but at 4K with the same Low settings, that figure falls to 89.6 FPS. This represents a reduction of approximately 60% when moving up two resolution tiers, indicating that the rendering load scales heavily with pixel throughput.

The scaling pattern becomes more pronounced at higher settings. With Ultra settings, the 1080p average is 94.7 FPS, which drops to 65.2 FPS at 1440p and then to 37 FPS at 4K. The gap between Low and Ultra settings at 4K is substantial: 89.6 FPS versus 37 FPS, a difference of 52.6 FPS. This suggests that while the RTX 3080 Ti has enough raw compute for lower presets at 4K, the Ultra preset’s additional effects and shading demands push the GPU to its limits.

The data indicates that at 1080p, the CPU is doing more of the heavy lifting, as the frame rates are high enough that the GPU is not saturated. At 4K, however, the GPU’s workload dominates, and the frame rates become more dependent on the graphics card’s capabilities. The 1440p results sit in a middle ground, with the Low preset hitting 157.6 FPS and the Ultra preset at 65.2 FPS, showing that this resolution is a balanced point for this combo.

CPU Role

The Intel Core i7-14700F is a 20-core, 28-thread processor from the Raptor Lake Refresh architecture, with a base clock of 2.10 GHz and a boost clock of 5.40 GHz. In Rust, which is known to be sensitive to single-threaded performance, the high boost clock is likely a key factor in the strong 1080p results. The processor’s Cinebench R23 single-core score of 5003 and multi-core score of 35443 indicate robust performance that can feed the GPU effectively at lower resolutions.

The CPU’s cache configuration includes 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. This large L3 cache is beneficial for games like Rust that have large, dynamic world data. The processor also supports both DDR4 and DDR5 memory, though the benchmark data does not specify which was used in this test, so the memory bandwidth’s contribution cannot be quantified from the provided results.

When compared to its nearest rivals, the i7-14700F’s average benchmark score of 54097 places it slightly behind the AMD Ryzen 9 9900X, which scores 54450, a delta of -0.6%. It is also 1.1% behind the AMD Ryzen 9 9900X3D, which scores 54681. However, the i7-14700F outperforms the Intel Xeon Phi 7290 by 1.2% and the AMD EPYC 7313P by 1.7%. These margins are small, suggesting that in CPU-bound scenarios, the i7-14700F is competitive with its immediate peers, though the 9900X series holds a slight edge in synthetic benchmarks.

How This Combo Ranks

In the benchmark database, this specific combination of the Intel Core i7-14700F and NVIDIA GeForce RTX 3080 Ti ranks 387th out of 1717 tested combos for Rust. This places it in the top 22.5% of all configurations tested for this game, indicating that it is a solid performer but not at the very top tier. The ranking reflects the balance between the CPU and GPU, where the RTX 3080 Ti’s 83rd percentile against all GPUs and the i7-14700F’s 94th percentile against all CPUs show that neither component is a weak link.

The combo’s rank is likely influenced by the GPU’s performance profile. The RTX 3080 Ti has an average benchmark score of 41224, which is 0.5% lower than the RTX 3090’s 41441, and 0.9% lower than the AMD Radeon Pro 5300’s 41610. It also trails the RTX 5070 by 1.1% and the Tesla M40 by 1.6%. These narrow deltas suggest that the RTX 3080 Ti is still a capable card, but it is not leading its class in raw compute, which may cap the combo’s ranking in a game as GPU-intensive as Rust at higher settings.

Measured FPS Breakdown

At 1080p, the measured frame rates show a clear progression from Low to Ultra. The Low preset averages 224.7 FPS, which is exceptionally high and indicates that the CPU is not a limiting factor at this resolution. The Medium preset drops to 148.4 FPS, and the High preset further reduces to 128.9 FPS. The Ultra preset averages 94.7 FPS, which is still playable but shows a substantial 130 FPS gap between the lowest and highest settings.

Moving to 1440p, the Low preset averages 157.6 FPS, which is a 67.1 FPS drop from 1080p, showing the GPU is beginning to take on more load. The Medium preset averages 102.5 FPS, and the High preset averages 90.9 FPS. The Ultra preset averages 65.2 FPS, which is a significant reduction from the 1080p figure, indicating that the GPU is now the primary bottleneck.

At 4K, the performance drops are more pronounced. The Low preset averages 89.6 FPS, which is still respectable, but the Medium preset falls to 60 FPS, and the High preset to 55.1 FPS. The Ultra preset averages just 37 FPS, which is below the threshold for smooth gameplay in a fast-paced survival title. The difference between Low and Ultra at 4K is 52.6 FPS, showing that the RTX 3080 Ti struggles with the highest settings at this resolution.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is built on the Ampere architecture with the GA102 chip, manufactured on an 8 nm process by Samsung. It features 12 GB of GDDR6X memory on a 384-bit bus, providing a bandwidth of 912.4 GB/s. This memory configuration is sufficient for Rust’s textures and world data, but the 4K Ultra results suggest that the GPU’s compute capabilities are the limiting factor rather than memory capacity.

The GPU has a base clock of 1365 MHz and a boost clock of 1665 MHz, with 10240 shading units, 320 TMUs, and 112 ROPs. It also includes 80 RT cores and 320 tensor cores, though Rust does not heavily utilize ray tracing. The FP32 performance is 34.10 TFLOPS, which is the primary metric for rasterized gaming workloads. The pixel rate is 186.5 GPixel/s and the texture rate is 532.8 GTexel/s, both of which are relevant for high-resolution rendering.

The RTX 3080 Ti’s nearest rival, the RTX 3090, performs 0.5% better in average benchmark scores, which is a negligible difference. However, the GPU’s 83rd percentile ranking against all GPUs indicates that it is in the upper tier but not the absolute top. For Rust specifically, the 4K Ultra average of 37 FPS shows that the GPU is struggling with the highest preset, while the 1080p Low average of 224.7 FPS demonstrates that the GPU has ample headroom when the CPU can keep up. This suggests that for players targeting 1440p or 1080p, the RTX 3080 Ti is a strong choice, but 4K Ultra is beyond its comfortable range.
