Rust

The Intel Core i7-12700K and AMD Radeon RX 7700 XT pairing delivers a very capable Rust experience, but the data reveals a system that shifts its bottleneck depending on resolution. At 1080p, the CPU flexes its muscles, pushing frame rates well past the 100 FPS mark on lower settings. However, as resolution climbs to 4K, the GPU takes over as the primary constraint, with frame rates dropping to sub-60 territory on higher presets. The measured results show a clear hierarchy: the combo ranks 717th out of 1717 tested combinations, indicating a solidly above-average setup for this title. This analysis breaks down the measured FPS data, the role of the GPU’s VRAM and clocks, the scaling pattern from 1080p to 4K, and how the CPU’s core configuration influences the final output.

FAQ

Q: What is the average frame rate at 1440p with High settings?

A: The measured average FPS at 2560x1440 with High settings is 72.2. This sits comfortably between the 1080p High result of 107.9 FPS and the 4K High result of 45.9 FPS, showing a predictable performance curve.

Q: How does the RX 7700 XT compare to its closest rival in raw benchmark scores?

A: The AMD Radeon RX 7700 XT has an average benchmark score of 30097, which is essentially tied with the NVIDIA GeForce RTX 5060 (score 30109, deltaPct 0). It is also just ahead of the AMD Radeon RX 570 (score 30158, deltaPct -0.2) and the NVIDIA Tesla M60 (score 29969, deltaPct 0.4).

Q: What is the maximum FPS achieved at 1080p in the measured data?

A: The highest average FPS recorded is 186, achieved at 1920x1080 with Low settings. This is a significant jump from the 129.4 FPS seen at 1440p Low, highlighting the CPU’s strength at lower resolutions.

Q: Does the CPU or GPU limit performance at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the average FPS drops to 31.5. This is the lowest result in the dataset, indicating that the GPU is heavily taxed at this resolution and setting combination, making it the primary limiting component.

Q: What is the L3 cache size available to the Core i7-12700K?

A: The Intel Core i7-12700K features a 25 MB shared L3 cache. This, combined with its 12 cores and 20 threads, contributes to its strong multi-threaded performance in benchmarks like Cinebench R23, where it scores 29241.

Q: What is the memory bandwidth of the RX 7700 XT?

A: The GPU has a memory bandwidth of 432.0 GB/s, facilitated by its 192-bit memory bus and 12 GB of GDDR6 memory. This bandwidth is crucial for feeding the GPU's 3456 shading units, especially at higher resolutions.

GPU Role

The AMD Radeon RX 7700 XT is the workhorse for visual fidelity in Rust, and its specifications clearly dictate the performance envelope at higher resolutions. The GPU is built on the RDNA 3.0 architecture and features 12 GB of GDDR6 memory on a 192-bit bus, yielding a bandwidth of 432.0 GB/s. This memory configuration is a key factor; with a boost clock of 2544 MHz and a game clock of 2171 MHz, the card can process a substantial amount of graphical data. Its raw compute capability is rated at 35.17 TFLOPS FP32, supported by 96 ROPs and 216 TMUs.

In the measured FPS data, the GPU’s role becomes more pronounced as resolution increases. At 4K, the performance gap between settings is vast. The drop from Low (76.9 FPS) to High (45.9 FPS) and then to Ultra (31.5 FPS) demonstrates the GPU's struggle to maintain high frame rates with increased graphical load. The benchmark results for the GPU show a Passmark G3D score of 22547, placing it in the 73rd percentile of all GPUs. Its average benchmark score of 30097 is nearly identical to the NVIDIA GeForce RTX 5060 (deltaPct 0), indicating that in synthetic tests, the two cards are direct competitors. This suggests that while the RX 7700 XT is a capable 1440p card, the high-end 4K Ultra preset in Rust exceeds its comfortable performance threshold, making it better suited for High settings at 1440p or 4K with lower presets.

Resolution Scaling

The measured FPS data reveals a clear and expected scaling pattern as resolution increases from 1920x1080 to 3840x2160. The most telling comparison is at High settings, where the average FPS drops from 107.9 at 1080p to 72.2 at 1440p, and finally to 45.9 at 4K. This represents a significant decline, with the 4K result being roughly 57% lower than the 1080p result. This steep drop-off indicates that the rendering load is scaling heavily with pixel count, putting increasing pressure on the GPU.

At Low settings, the scaling is even more dramatic in absolute terms. The 1080p result of 186 FPS is exceptionally high, suggesting that the CPU is capable of feeding the GPU more than enough frames at this resolution. However, at 1440p Low, the FPS drops to 129.4, and at 4K Low, it falls to 76.9. The drop from 1080p to 1440p (a 56.6 FPS reduction) is larger than the drop from 1440p to 4K (a 52.5 FPS reduction). This pattern suggests that at 1080p Low, performance is likely bottlenecked by the CPU, as the GPU has plenty of headroom. As resolution increases, the GPU becomes the limiting factor, which explains the more consistent FPS declines at higher resolutions. The data indicates that for players seeking high refresh rates, 1080p is the target resolution, while 4K is only viable for a more cinematic, lower-FPS experience.

Measured FPS Breakdown

The dataset provides a comprehensive look at performance across three resolutions and four settings. At 1920x1080, the results are strong across the board. Low settings produce an average of 186 FPS, which is the highest in the entire dataset. Medium settings yield 124 FPS, while High settings produce 107.9 FPS. Pushing to Ultra at 1080p results in 78.4 FPS, which is still very playable but shows the performance cost of maximum visual fidelity.

Moving to 2560x1440, the frame rates remain respectable. The Low preset delivers 129.4 FPS, a solid number for competitive play. Medium follows at 88.6 FPS, and High dips to 72.2 FPS. At Ultra, the average FPS drops to 54.7, which is the first sub-60 result in the dataset, indicating that the GPU is beginning to feel the strain at this resolution with maximum settings.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings manage an average of 76.9 FPS, which is surprisingly playable. Medium drops to 53.4 FPS, and High falls further to 45.9 FPS. The Ultra preset produces just 31.5 FPS, which is not ideal for a smooth experience. The data shows a clear hierarchy: 1080p is for high refresh rates, 1440p offers a balanced experience with High settings, and 4K requires Low or Medium settings to maintain acceptable performance.

CPU Role

The Intel Core i7-12700K plays a critical role in ensuring the RX 7700 XT is fed with enough data, particularly at lower resolutions. With 12 cores and 20 threads based on the Alder Lake architecture, this CPU provides substantial multi-threading capability. Its boost clock of 5.00 GHz is instrumental for single-threaded performance, which is often critical in game logic and physics. The CPU's benchmark scores reinforce its strength: a Cinebench R23 multi-core score of 29241 and a single-core score of 4128 demonstrate a balanced performance profile. Its Passmark multithread score of 34404 places it in the 89th percentile of all CPUs.

The CPU’s impact is most evident when comparing the 1080p and 1440p Low settings results. At 1080p Low, the GPU has minimal work, allowing the CPU to push the frame rate to 186 FPS. When resolution increases to 1440p Low, the FPS drops to 129.4. This drop is primarily due to the GPU taking on more rendering work, but the CPU is still able to maintain a high frame rate. The data suggests that the i7-12700K is not a significant bottleneck in this configuration for most settings. Its performance is closely matched to rivals like the AMD Ryzen 7 PRO 5845 (deltaPct -0.3) and the Intel Core i7-13700T (deltaPct 0.6), showing it is a top-tier performer for gaming. The CPU's robust single-thread performance, evidenced by its 3dmark_single_thread score of 1043, ensures that Rust’s engine can run efficiently, allowing the GPU to be the primary limiter at higher resolutions.
