# Resolution Scaling

The measured FPS data for Rust with the Intel Core Ultra 5 245 and AMD Radeon RX 9070 reveals a clear pattern of performance degradation as resolution increases. At 1080p with Low settings, the combo achieves 212 FPS, but this drops to 146 FPS at 1440p and further to 86 FPS at 2160p. That represents a 59% reduction from 1080p to 4K at Low settings, which strongly suggests the GPU becomes the primary bottleneck at higher resolutions.

Looking at the High preset, the scaling is similar: 120 FPS at 1080p, 83 FPS at 1440p, and 49 FPS at 4K. The drop from 1080p to 1440p is 31%, while the drop from 1440p to 4K is 41%. This accelerating decline as resolution increases is characteristic of a GPU-bound scenario, where the Radeon RX 9070's rendering workload grows faster than the CPU's ability to feed it frames.

The Medium settings row provides the most complete data with min and max FPS values. At 1080p Medium, the average is 142 FPS with a range of 121 to 164 FPS. At 1440p Medium, the average falls to 98 FPS with a range of 83 to 113 FPS. At 4K Medium, the average drops to 58 FPS with a range of 49 to 67 FPS. The tight min-max spread at each resolution suggests consistent frame pacing rather than sporadic stuttering.

Ultra settings show the most severe scaling penalty. At 1080p Ultra, the combo produces 91 FPS, which drops to 63 FPS at 1440p and 37 FPS at 4K. The 4K Ultra result is barely playable by most standards, indicating that this settings tier pushes the GPU to its limits with this particular CPU pairing.

What the data implies is that the RX 9070 has substantial headroom at lower resolutions but becomes the limiting factor as pixel count increases. At 1080p Low, the 212 FPS result likely approaches the CPU's frame generation ceiling, since the Core Ultra 5 245 with its 14 cores and 14 threads can only process so many draw calls per second. As resolution climbs, the GPU's fill rate and shading capacity take over as the dominant constraint.

The scaling behavior across all four settings presets follows a consistent pattern, but the magnitude of the drop from Medium to Ultra at each resolution deserves attention. At 1080p, Medium to Ultra costs 36% of performance. At 1440p, the same settings jump costs 36%. At 4K, it costs 36%. This uniformity suggests the settings presets scale rendering features proportionally rather than introducing sudden bottlenecks.

FAQ

Q: What is the best resolution for this combo in Rust?

A: The data shows 1440p as the sweet spot. At 1440p High, the combo achieves 83 FPS average, which is smooth for a survival game. At 4K High, FPS drops to 49, which may feel sluggish. At 1080p, the combo exceeds 120 FPS on High and 212 FPS on Low, but the visual fidelity at 1440p is better suited to the GPU's capabilities.

Q: How does the Low preset compare to Ultra in terms of FPS gain?

A: At every resolution, Low offers roughly 2.3 times the FPS of Ultra. At 1080p, Low produces 212 FPS versus 91 FPS on Ultra. At 1440p, Low produces 146 FPS versus 63 FPS on Ultra. At 4K, Low produces 86 FPS versus 37 FPS on Ultra. This consistent ratio suggests the settings presets scale uniformly.

Q: Is the CPU or GPU more responsible for the 1080p Low score of 212 FPS?

A: The 212 FPS result at 1080p Low likely reflects a balance between both components. The Core Ultra 5 245 has a 5.10 GHz boost clock and 14 cores, which can handle Rust's simulation and draw call overhead. The RX 9070 with 3584 shading units can rasterize at high speed. At 1080p Low, neither component appears to be fully saturated, but the CPU's frame generation limit is closer than at higher resolutions.

Q: What is the minimum FPS at 4K Medium, and is it playable?

A: The 4K Medium row shows a minimum FPS of 49 and a maximum of 67, with an average of 58 FPS. While the average is above the 60 FPS threshold, the minimum of 49 FPS indicates that brief dips below 60 FPS occur during intense scenes, which could affect gameplay smoothness in Rust's multiplayer environments.

Q: How does this combo rank among all tested combinations for Rust?

A: The comboRankInGame places this pairing at 781 out of 2953 tested combos, which places it in the top 26% of all configurations tested for Rust. This ranking reflects the balance between the CPU and GPU rather than raw performance alone, as some higher-ranked combos may pair stronger CPUs with the same GPU.

Q: Does the data include any overclocking or stability information?

A: No, the measured FPS data includes only average, minimum, and maximum FPS values for each resolution and settings preset. The minimum FPS values are only provided for Medium settings at each resolution, showing 121 FPS at 1080p, 83 FPS at 1440p, and 49 FPS at 4K. No overclocking results are included in the fact pack.

How This Combo Ranks

The comboRankInGame field places this Intel Core Ultra 5 245 and AMD Radeon RX 9070 pairing at rank 781 out of 2953 tested combinations for Rust. This percentile position of roughly the top 26% indicates a solid but not elite configuration for this specific game.

What makes this ranking noteworthy is the discrepancy between the CPU's and GPU's individual percentile standings. The Core Ultra 5 245 sits at the 90th percentile among all CPUs tested in the broader benchmark suite, while the Radeon RX 9070 sits at the 69th percentile among all GPUs. The combined rank of 781 out of 2953 suggests that the GPU's lower relative standing pulls the combo down from what the CPU alone might achieve.

The nearestRivals data for the CPU shows it trading blows with several strong competitors. The AMD Ryzen 7 PRO 5755G scores 0.4% higher on average, while the AMD Ryzen 9 7900 scores 0.5% higher. The Intel Xeon Gold 5318H scores 0.6% lower, and the Intel Core i5-14600K scores 0.8% lower. These tiny deltas mean the CPU is essentially on par with a range of desktop and workstation processors, which bodes well for consistent frame delivery in Rust.

For the GPU, the nearestRivals present a more interesting picture. The NVIDIA GeForce GTX TITAN Z scores 0.6% higher on average, while the AMD Radeon RX 6800S scores 0.8% lower. The NVIDIA GeForce RTX 3080 Mobile scores 1.1% higher, and the NVIDIA GeForce RTX 2080 SUPER scores 1.2% lower. These comparisons show the RX 9070 in the same performance band as several older and mobile GPUs, which is surprising given its newer RDNA 4.0 architecture and 16 GB of GDDR6 memory.

The ranking data suggests that for Rust specifically, the combo's performance is more dependent on the GPU than the CPU. Rust is known for being CPU-heavy in its simulation and entity update logic, but the measured FPS at 4K Ultra (37 FPS) versus 1080p Low (212 FPS) shows a 5.7x difference, which is far larger than what CPU limitations alone would produce. This indicates that the GPU's rasterization throughput dominates the combo's ranking in this game.

Settings Recommendations

The measured FPS data provides clear guidance for optimal settings at each resolution. At 1080p, the Medium preset offers the best balance of visual quality and performance. The 142 FPS average with a minimum of 121 FPS ensures smooth gameplay even in Rust's most demanding moments, such as raiding bases or navigating heavily populated servers. The High preset at 120 FPS is also viable, but the Medium preset's higher minimum FPS provides more headroom against frame dips.

At 1440p, the Medium preset again emerges as the recommended choice. The 98 FPS average with a minimum of 83 FPS delivers a solid experience for competitive and survival gameplay. The High preset at 83 FPS is playable but approaches the threshold where frame drops become noticeable. The Ultra preset at 63 FPS is borderline, with the lack of min/max data suggesting potential variability that could impact gameplay.

At 4K, the Low preset is the only option that maintains acceptable frame rates. The 86 FPS average at 4K Low is surprisingly strong, likely due to Rust's scalable rendering pipeline. The Medium preset at 58 FPS with a minimum of 49 FPS could work for less demanding playstyles, but the risk of dropping below 50 FPS during intense scenes makes it a risky choice. High at 49 FPS and Ultra at 37 FPS are not recommended for competitive play.

For players prioritizing visual fidelity over frame rate, the 1440p High preset at 83 FPS offers the best compromise. The quality difference between High and Ultra is often subtle in Rust, and the 24% performance gain from dropping from Ultra to High at 1440p is substantial. At 4K, the gap between Low and Medium is 28 FPS (86 versus 58), which is significant enough that Low is the clear choice unless visual quality is the absolute priority.

Measured FPS Breakdown

At 1920x1080, the measured results show a clear hierarchy across settings. Low settings produce an average of 212 FPS, which is the highest score in the entire dataset. Medium settings average 142 FPS with a range of 121 to 164 FPS, providing a buffer against frame drops. High settings average 120 FPS, while Ultra settings average 91 FPS. The 1080p resolution demonstrates the combo's ability to drive high refresh rate monitors at lower settings.

At 2560x1440, performance scales down proportionally. Low settings average 146 FPS, representing a 31% drop from 1080p Low. Medium settings average 98 FPS with a range of 83 to 113 FPS, which is a 31% drop from 1080p Medium. High settings average 83 FPS, a 31% drop from 1080p High. Ultra settings average 63 FPS, a 31% drop from 1080p Ultra. The consistency of this 31% reduction across all settings suggests that resolution scaling affects all rendering paths equally.

At 3840x2160, the performance penalty becomes more severe. Low settings average 86 FPS, representing a 41% drop from 1440p Low and a 59% drop from 1080p Low. Medium settings average 58 FPS with a range of 49 to 67 FPS, which is a 41% drop from 1440p Medium. High settings average 49 FPS, a 41% drop from 1440p High. Ultra settings average 37 FPS, a 41% drop from 1440p Ultra. The 4K resolution shows a steeper scaling curve than the 1080p to 1440p transition, indicating that the GPU's memory bandwidth and fill rate become more critical at this pixel density.

The Medium settings rows are the only ones with complete min/max data. At 1080p, the spread is 121 to 164 FPS, a range of 43 FPS. At 1440p, the spread is 83 to 113 FPS, a range of 30 FPS. At 4K, the spread is 49 to 67 FPS, a range of 18 FPS. The narrowing range as resolution increases suggests that frame pacing becomes more consistent when the GPU is more heavily loaded, which is counterintuitive but may reflect lower CPU-side variability at higher resolutions.

CPU Role

The Intel Core Ultra 5 245 brings 14 cores and 14 threads to this pairing, which is notable because Rust's simulation and entity update systems can leverage multiple threads. The lack of hyperthreading means each core handles one thread, but the 14 physical cores provide substantial parallel processing capability. The base clock of 3.50 GHz and boost clock of 5.10 GHz offer strong single-threaded performance when needed, which is critical for Rust's main game loop.

The CPU's cache hierarchy includes 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 24 MB of shared L3 cache. This configuration supports efficient data access for the game's many entity updates and network operations. The 102.4 GB/s dual-channel DDR5 memory bandwidth provides sufficient throughput for feeding both the CPU and GPU with data, though the measured FPS data suggests this is not a bottleneck at any resolution.

In the broader benchmark suite, the Core Ultra 5 245 achieves a Cinebench R23 multicore score of 32924 and a single-core score of 4648. These scores place it at the 90th percentile among all CPUs, with an average benchmark score of 48995. The nearest rivals include the AMD Ryzen 7 PRO 5755G at 0.4% higher average score, the AMD Ryzen 9 7900 at 0.5% higher, the Intel Xeon Gold 5318H at 0.6% lower, and the Intel Core i5-14600K at 0.8% lower. This tight clustering indicates the CPU is well-matched against several strong competitors.

For Rust specifically, the CPU's role is most evident at 1080p Low where the 212 FPS result approaches the upper limit of what this processor can generate. The PassMark single-thread score of 4394 and multithread score of 38706 indicate strong performance in both single-threaded and multi-threaded workloads. Rust's server-side simulation runs on the host, but the client-side entity updates and rendering calls benefit from the CPU's high boost clock and efficient Arrow Lake architecture.

GPU Role

The AMD Radeon RX 9070 with its Navi 48 chip and RDNA 4.0 architecture provides the rendering horsepower for this combo. The GPU features 3584 shading units, 224 TMUs, and 128 ROPs, which are substantial numbers for rasterization-heavy games like Rust. The boost clock of 2520 MHz and game clock of 2070 MHz deliver the raw compute throughput needed for high-resolution rendering.

The 16 GB of GDDR6 memory on a 256-bit bus provides 644.6 GB/s of bandwidth. This memory configuration is particularly relevant for Rust, which can use significant VRAM at higher settings and resolutions due to its large textures and draw distances. The 4K Ultra result of 37 FPS suggests that memory bandwidth and capacity are sufficient but that the GPU's compute units become saturated with the rendering workload.

The GPU's FP32 performance of 36.13 TFLOPS and texture rate of 564.5 GTexel/s indicate strong raw compute capabilities. In the PassMark G3D benchmark, the RX 9070 scores 25381, placing it at the 69th percentile among all GPUs. The nearest rivals include the NVIDIA GeForce GTX TITAN Z at 0.6% higher, the AMD Radeon RX 6800S at 0.8% lower, the NVIDIA GeForce RTX 3080 Mobile at 1.1% higher, and the NVIDIA GeForce RTX 2080 SUPER at 1.2% lower.

The GPU's role in this combo becomes more pronounced at higher resolutions. From 1080p Low to 4K Low, the FPS drops from 212 to 86, a 59% reduction. From 1080p Ultra to 4K Ultra, the FPS drops from 91 to 37, a 59% reduction. This consistent scaling indicates that the GPU is the dominant factor in determining performance at all settings, with the CPU providing a sufficiently high frame ceiling to avoid becoming a bottleneck at lower resolutions.

The Radeon RX 9070's support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 ensures compatibility with Rust's rendering API. The 3DMark Steel Nomad DX12 score of 6290 and Geekbench Vulkan score of 58705 provide additional context for the GPU's DirectX 12 and Vulkan performance, both of which are relevant for Rust's modern rendering pipeline.
