The RTX 4080’s substantial compute resources drive frame rates that exceed 100 FPS at 1440p High, while the Core Ultra 5 225’s strong single-thread performance keeps minimum frame rates respectable even when the GPU is stressed.

Resolution Scaling

The measured FPS data reveals a clear pattern of GPU-bound scaling as resolution increases. At 1080p Low, the combo produces 258 FPS, which drops to 117 FPS at 4K Low—a 55% reduction in frame rate. This dramatic falloff indicates that the RTX 4080 is the limiting factor at higher resolutions, as the CPU has ample headroom at lower pixel counts.

At High settings, the scaling is more moderate: 163 FPS at 1080p falls to 112 FPS at 1440p, then further to 66 FPS at 4K. The 1440p to 4K transition sees a 41% performance loss, which aligns with the 2.25x pixel count increase. This suggests the GPU is fully utilized at 4K, while at 1080p the frame rate is likely constrained by the CPU or other system bottlenecks.

The Medium settings tier shows similar behavior: 193 FPS at 1080p, 133 FPS at 1440p, and 79 FPS at 4K. The 4K Medium result of 79 FPS with a minimum of 67 FPS indicates playable performance, but the gap between 1440p and 4K widens as settings increase. At Ultra, the 4K average of 50 FPS represents a 60% drop from 1080p Ultra’s 124 FPS, making 4K Ultra the only configuration that falls below the 60 FPS threshold.

The data indicates that this combo is best suited for 1440p gaming, where High settings achieve 112 FPS and even Ultra maintains 85 FPS. At 1080p, the system excels with frame rates above 160 FPS on High, but the CPU’s 10 cores and 10 threads may limit performance in CPU-intensive scenes, as evidenced by the 4K Low result exceeding 4K High by 51 FPS—a sign that the GPU is not the sole bottleneck at lower settings.

GPU Role

The NVIDIA GeForce RTX 4080 is the dominant component in this combo, driving performance across all resolutions. Its 16 GB of GDDR6X memory on a 256-bit bus delivers 716.8 GB/s of bandwidth, which is more than sufficient for Rust’s texture-heavy environments at 4K. The GPU’s 9,728 shading units and 76 RT cores provide the compute power needed for the game’s lighting and shadow effects.

The RTX 4080’s boost clock of 2,505 MHz, combined with its 48.74 TFLOPS FP32 performance, explains the strong frame rates at 1440p and 1080p. The GPU’s 86th percentile ranking among all GPUs places it near the top of the performance spectrum, and its average benchmark score of 54,247 is within 0.1% of the RTX 4080 SUPER, indicating this is a top-tier configuration.

The 4K results highlight the GPU’s capabilities and limitations. At Low settings, the 117 FPS average shows the GPU can handle the pixel count when graphical effects are reduced. However, at Ultra settings, the 50 FPS result indicates the GPU is fully saturated, with the 16 GB VRAM and 716.8 GB/s bandwidth being sufficient but the compute units reaching their limit. The Medium settings result of 79 FPS with a 67 FPS minimum demonstrates that the RTX 4080 can maintain playable frame rates at 4K with moderate settings.

CPU Role

The Intel Core Ultra 5 225 provides solid single-thread performance that is crucial for Rust’s game logic and simulation. With 10 cores and 10 threads, the CPU has a base clock of 3.30 GHz and a boost clock of 4.90 GHz, delivering strong performance in the game’s CPU-bound scenarios. The CPU’s 20 MB of shared L3 cache helps with data locality, though the 10-core configuration may limit multi-threaded scaling in Rust’s entity-heavy servers.

The CPU’s benchmark scores support its role in this combo. The Cinebench R23 single-core score of 3,655 and multi-core score of 25,891 indicate strong single-thread performance, which is essential for Rust’s frame pacing. The PassMark single-thread score of 4,412 and multi-thread score of 30,459 show the CPU is capable of feeding the RTX 4080 at 1080p, where frame rates exceed 250 FPS on Low settings.

The 85th percentile ranking among all CPUs and average benchmark score of 36,938 place it in line with the AMD Ryzen 5 5600F (deltaPct 0) and AMD Ryzen 5 5500X3D (deltaPct -0.2). This indicates the CPU is a capable partner for the RTX 4080, though the 10-core, 10-thread configuration may become a bottleneck in scenarios with many players or complex bases. The 4K Low result of 117 FPS versus 1080p Low’s 258 FPS shows that the CPU can drive high frame rates at lower resolutions, but the RTX 4080’s pixel throughput limits performance at 4K.

The CPU’s 65W TDP and DDR5 memory support with 102.4 GB/s bandwidth provide a solid foundation for gaming, though the lack of an unlocked multiplier limits overclocking potential. The integrated Arc Xe-LPG Graphics with 16 execution units is not relevant for gaming with the RTX 4080 installed, but it does provide a fallback for troubleshooting. Overall, the Core Ultra 5 225 is a capable mid-range processor that complements the RTX 4080 without bottlenecking it at standard gaming resolutions.
