# Resolution Scaling

The measured FPS data for Rust on this platform reveals a pronounced GPU-bound scaling pattern as resolution increases. At 1080p with Low settings, the system delivers 190 FPS, but this drops to 130 FPS at 1440p and further to 77 FPS at 4K. That represents a 59.5% reduction from 1080p to 4K at Low settings, indicating that the Radeon RX 7700 XT becomes the dominant limiting factor as pixel count rises.

The scaling behavior across all settings tells a consistent story. At Medium settings, the average FPS falls from 127 at 1080p to 88 at 1440p (a 30.7% drop), then to 52 at 4K (a 59.1% drop from 1080p). At High settings, the progression is 107 FPS at 1080p, 74 FPS at 1440p, and 44 FPS at 4K — a 58.9% total reduction. Ultra settings show the steepest absolute decline, moving from 82 FPS at 1080p to 56 FPS at 1440p and 33 FPS at 4K, a 59.8% drop across the resolution range.

These percentages cluster tightly around 59-60%, which is a hallmark of GPU-bound rendering. If the CPU were the limiting factor, the FPS would remain relatively flat as resolution increases, since the processor's workload does not scale with pixel count. The data instead shows near-linear scaling with pixel density, confirming that the RX 7700 XT is the primary bottleneck in this configuration for Rust.

The 4K results are particularly telling. Even at Low settings, the system only manages 77 FPS at 3840x2160, while Ultra settings drop to 33 FPS. This wide spread between settings at 4K (44 FPS difference between Low and Ultra) demonstrates that the GPU has ample headroom to respond to graphical quality changes, further supporting the conclusion that pixel throughput — not geometry or draw-call processing — is the constraining factor.

# GPU Role

The AMD Radeon RX 7700 XT brings 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. This memory configuration is directly relevant to Rust's performance at higher resolutions, where texture streaming and large world data place significant demands on memory throughput. The 12 GB capacity ensures that capacity is unlikely to be exceeded even at 4K Ultra, allowing the measured FPS to reflect raw compute and bandwidth limits rather than memory swapping.

The GPU's clocks are a key factor in the scaling pattern observed. With a base clock of 1435 MHz, a game clock of 2171 MHz, and a boost clock of 2544 MHz, the RX 7700 XT maintains substantial headroom under load. The 2544 MHz boost ceiling explains why the card can still deliver 77 FPS at 4K Low — it is able to ramp up to maximum frequency when the rendering workload is simplified. At higher settings, the additional shader work from 3456 shading units and 216 texture mapping units keeps the GPU busy, but the boost clock cannot fully compensate for the increased pixel and texture demands.

The GPU's compute capabilities are substantial for its class. The 35.17 TFLOPS FP32 throughput and 549.5 GTexel/s texture rate position this card well above entry-level options. In Rust specifically, the texture rate is critical because the game's terrain and building textures require rapid texel fetching, particularly at higher resolutions where more pixels must be filled. The 96 ROPs deliver a pixel rate of 244.2 GPixel/s, which directly caps the fill-rate performance at 4K — explaining why Ultra settings at 3840x2160 only achieve 33 FPS.

Comparing to its nearest rivals in the GPU benchmark database, the RX 7700 XT scores 22547 in PassMark G3D, placing it 0.5% ahead of the NVIDIA GeForce RTX 5060 Mobile and 1.7% ahead of the AMD Radeon RX 5700. It trails the RTX 4060 Mobile by 0.8% and the RTX 2080 by 1.5%. This tight clustering around the 22,500-22,900 score range indicates that the RX 7700 XT is competitively positioned, though the measured Rust results show it performing strongly at 1080p and adequately at 1440p, while 4K requires settings compromises.

# How This Combo Ranks

The combination of the Intel Core i7-13700K and AMD Radeon RX 7700 XT achieves a rank of 1380 out of 3723 tested combos in Rust. This places the configuration in the 63rd percentile of all tested combinations, meaning it outperforms roughly 63% of systems tested for this game while trailing the top 37%.

This ranking reflects a balanced pairing where the CPU is substantially stronger than the GPU. The i7-13700K sits at the 89th percentile among all CPUs, while the RX 7700 XT is at the 67th percentile among all GPUs. The combo rank of 63rd percentile falls between these two figures, indicating that Rust's performance is being dragged down by the GPU relative to what the CPU alone could support. If the game were entirely CPU-bound, the combo rank would likely approach the CPU's 89th percentile; the fact that it sits at 63rd confirms the GPU-limited nature of most Rust workloads.

Within the context of the 3723 combos tested, being at rank 1380 means there are 2343 slower configurations and 1381 faster ones. The performance spread is meaningful — the difference between this combo and top-tier systems (likely pairing the i7-13700K with a flagship GPU) would be substantial, particularly at 4K where the GPU's 33-77 FPS range across settings shows clear limitations. At 1080p, however, the combo is much more competitive, with Low settings reaching 190 FPS and High settings maintaining 107 FPS, suggesting that the rank improves at lower resolutions.

# CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on Raptor Lake architecture, manufactured on Intel's 10 nm process. Its 3.40 GHz base clock and 5.40 GHz boost clock provide substantial single-thread performance, which is essential for Rust's game logic and physics simulation. The processor features 30 MB of shared L3 cache, 2 MB of L2 cache per core, and 80 KB of L1 cache per core, providing ample fast memory for frequently accessed game data.

In synthetic benchmarks, the i7-13700K demonstrates strong multi-threaded capabilities. Its Cinebench R23 multicore score of 30745 and Geekbench multicore score of 19429 place it firmly in high-end desktop territory. The PassMark multithread score of 45887 and floating point math score of 114867 indicate that the CPU can handle complex simulation workloads without becoming a bottleneck, even when the GPU is heavily loaded.

However, the measured Rust performance tells a more nuanced story. The fact that FPS scales nearly linearly with resolution — dropping from 190 FPS at 1080p Low to 77 FPS at 4K Low — suggests that the CPU is not the limiting factor at any resolution tested. If the CPU were struggling, we would expect to see similar FPS values across resolutions, or at least a plateau at the CPU's maximum frame delivery rate. Instead, the GPU's decreasing throughput as resolution rises is the dominant factor.

The i7-13700K's single-thread performance, measured at 2116 in Cinebench R23 single-core and 4333 in PassMark single-thread, is more than sufficient for Rust's primary game thread. The 16 cores and 24 threads provide ample parallel processing for background tasks, asset streaming, and server communication, ensuring that the GPU receives a consistent stream of draw calls and rendering commands. The 89th percentile CPU ranking versus the 67th percentile GPU ranking confirms that the processor has headroom to spare in this pairing.

# Settings Recommendations

The measured data provides clear guidance for optimizing the Rust experience on this hardware. For players prioritizing maximum frame rate, 1080p Low settings deliver 190 FPS, which is ideal for competitive play or high-refresh-rate monitors. However, this comes at the cost of visual fidelity, as Low settings significantly reduce texture quality and draw distances.

For the best balance of visual quality and performance, 1440p Medium settings are the recommended choice. This configuration achieves 88 FPS average with a minimum of 74 FPS and a maximum of 101 FPS, providing a smooth experience on standard 144Hz displays while maintaining acceptable visual quality. The 74 FPS minimum ensures that frame drops remain above the 60 FPS threshold for most of the gameplay.

At 1080p, Medium settings deliver 127 FPS with a minimum of 108 FPS, which is another strong option for players who want higher frame rates without sacrificing too much visual quality. The 108 FPS minimum keeps gameplay fluid even during intense scenes with many players or complex building structures.

For 4K gaming, the data shows that only Low settings (77 FPS) provide a genuinely playable experience. Medium settings at 52 FPS are technically playable but may feel less smooth, while High (44 FPS) and Ultra (33 FPS) are not recommended for competitive or fast-paced gameplay. Players with 4K monitors should accept Low settings or consider dropping to 1440p for a better experience.

The 1440p High setting at 74 FPS is a viable alternative to Medium, offering improved visual quality at the cost of 14 FPS on average. However, the lack of a measured minimum FPS for High settings makes it harder to guarantee consistent performance, whereas Medium's 74 FPS minimum provides more certainty.

3840x2160:

• Low: 77 FPS average (no min/max recorded)
• Medium: 52 FPS average, 44 FPS minimum, 59 FPS maximum
• High: 44 FPS average (no min/max recorded)
• Ultra: 33 FPS average (no min/max recorded)

The data reveals a consistent pattern where Low settings provide roughly 1.5x the frame rate of Medium settings at each resolution. At 1080p, the jump from Low to Medium costs 63 FPS (190 to 127), while at 1440p it costs 42 FPS (130 to 88), and at 4K it costs 25 FPS (77 to 52). This diminishing absolute difference at higher resolutions reflects the GPU's reduced headroom as pixel count increases.

The Medium settings rows are the only ones with complete min/max data, providing insight into frame time consistency. At 1080p, the 108-146 FPS range shows a 38 FPS spread, while at 1440p the 74-101 FPS range shows a 27 FPS spread, and at 4K the 44-59 FPS range shows a 15 FPS spread. The narrowing range at higher resolutions indicates that frame pacing becomes more consistent when the GPU is more heavily loaded, likely because the CPU has more time to prepare frames between GPU completions.

The Ultra settings show the steepest degradation: 82 FPS at 1080p, 56 FPS at 1440p, and 33 FPS at 4K. This represents a 59.8% drop from 1080p to 4K, nearly identical to the Low settings' 59.5% drop, confirming that the resolution scaling is consistent regardless of quality preset. The High settings follow the same pattern with a 58.9% reduction, and Medium settings show a 59.1% reduction. This uniformity across all settings strongly indicates that the GPU's pixel throughput is the sole determining factor in resolution scaling for this combo.
