# Rust Performance Analysis: Intel Core Ultra 5 225 + NVIDIA GeForce RTX 4070 Ti

This combination of Intel's 10-core Core Ultra 5 225 and NVIDIA's RTX 4070 Ti delivers a robust Rust experience across all tested resolutions, with the data showing a clear progression from GPU-bound at 4K to CPU-influenced at 1080p. The measured frame rates position this combo in the 91st percentile of all tested configurations (rank 266 of 2,953), indicating strong overall performance for a survival title that is known to stress both processor and graphics subsystems heavily.

Resolution Scaling

The FPS data reveals distinct scaling patterns as resolution drops from 4K to 1080p. At 3840x2160 with High settings, the combo produces 61 FPS average. Moving to 2560x1440 at the same settings yields 103 FPS — a 69% improvement. Dropping further to 1920x1080 produces 150 FPS, which is 46% higher than the 1440p result. This scaling curve — 61 → 103 → 150 FPS — shows diminishing returns as resolution decreases, which is classic behavior when the GPU becomes less of a bottleneck.

At Low settings, the scaling is even more pronounced. The 4K result of 107 FPS jumps to 182 FPS at 1440p (a 70% increase), then to 258 FPS at 1080p (a 42% increase from 1440p). The fact that 1080p Low exceeds 250 FPS suggests that the CPU is beginning to assert its influence at this resolution, as the RTX 4070 Ti has ample headroom to render far more frames if the processor could keep pace.

The Medium settings row provides the most complete data with min/max values. At 4K Medium, the average is 72 FPS with a range of 61-83 FPS. At 1440p Medium, the average rises to 122 FPS (range 104-140), and at 1080p Medium, it reaches 177 FPS (range 151-204). The spread between min and max FPS widens slightly at lower resolutions — from 22 FPS at 4K to 53 FPS at 1080p — which indicates that frame time variance grows when the CPU is more involved in the rendering pipeline.

Ultra settings tell a steeper story. The 4K Ultra average is 46 FPS, which is playable but not ideal for competitive scenarios. At 1440p Ultra, it rises to 78 FPS, and at 1080p Ultra, it hits 114 FPS. The scaling from 4K to 1440p at Ultra is 70% improvement, while 1440p to 1080p is 46% — nearly identical percentages to the High settings scaling, suggesting consistent GPU-bound behavior across these two quality presets.

The overall pattern indicates that at 4K, the RTX 4070 Ti is the limiting component across all settings. At 1440p, the system achieves a good balance, with frame rates ranging from 78 FPS at Ultra to 182 FPS at Low. At 1080p, the CPU's role becomes more significant, particularly at Low settings where the 258 FPS result likely approaches the processor's practical limit in Rust.

GPU Role

The RTX 4070 Ti is built on the Ada Lovelace architecture using the AD104 chip, manufactured on a 5 nm process at TSMC with 35,800 million transistors on a 294 mm² die. Its 12 GB of GDDR6X memory operates across a 192-bit bus, delivering 504.2 GB/s of bandwidth. The memory clock is listed at 1313 MHz with 21 Gbps effective speed. The GPU's base clock is 2310 MHz with a boost clock of 2610 MHz.

In Rust, the GPU's memory subsystem plays a critical role due to the game's large, persistent world and frequent texture streaming. The 12 GB VRAM capacity appears sufficient for all tested settings, as the benchmark data shows no anomalous performance collapses that would indicate memory capacity issues. The 504.2 GB/s bandwidth provides adequate throughput for the game's asset loading requirements, though the 192-bit bus is narrower than some higher-tier cards.

The GPU's compute capabilities are substantial — 7,680 shading units, 240 TMUs, and 80 ROPs, with a pixel rate of 208.8 GPixel/s and texture rate of 626.4 GTexel/s. The FP32 performance of 40.09 TFLOPS indicates strong raw compute that benefits Rust's physics simulation and building mechanics. The 60 RT cores and 240 tensor cores are present but less relevant for Rust, which does not heavily utilize ray tracing.

The GPU's percentile ranking of 84 versus all GPUs, with an average benchmark score of 44,795, places it in the upper tier of graphics cards. Its nearest rivals in the benchmark database include the RTX 5090 Mobile (0.8% higher average score), AMD Radeon Pro 5500 XT (1.3% higher), and RTX A6000 (1.6% lower). This clustering indicates that the RTX 4070 Ti sits at a performance plateau where minor architectural differences produce negligible benchmark deltas.

At 4K resolution, the GPU's limitations are evident. The jump from 46 FPS at Ultra to 107 FPS at Low represents a 133% improvement, which shows that reducing graphical load dramatically increases throughput. This behavior confirms that at 4K, the GPU is the primary constraint, and users seeking higher frame rates must sacrifice visual quality rather than rely on CPU headroom.

CPU Role

The Intel Core Ultra 5 225 features 10 cores and 10 threads, with a base clock of 3.30 GHz and a boost clock of 4.90 GHz. It belongs to the Arrow Lake-S architecture (Core Ultra Series 2), manufactured on a 3 nm process at TSMC with 17,800 million transistors on a 243 mm² die. The cache hierarchy includes 192 KB L1 per core, 3 MB L2 per core, and 20 MB of shared L3 cache. Memory support is DDR5 with dual-channel configuration and 102.4 GB/s bandwidth.

The CPU's benchmark results show strong single-threaded performance with a Cinebench R23 single-core score of 3,655 and multi-core score of 25,891. The PassMark single-thread score of 4,412 and multithread score of 30,459 provide additional context. The processor's percentile ranking of 85 versus all CPUs, with an average benchmark score of 36,938, positions it competitively against peers like the AMD Ryzen 5 5600F (0% delta), Ryzen 5 5500X3D (-0.2%), and Ryzen AI 7 PRO 450 (-0.4%).

In Rust, the CPU's role becomes increasingly apparent at lower resolutions. The 1080p Low result of 258 FPS suggests the processor is approaching its practical limit in this title, as the GPU could theoretically render more frames if the CPU could feed it faster. The 10-core/10-thread configuration without hyper-threading means that each core handles one thread, which can be a limitation in heavily threaded scenarios, though Rust's core utilization patterns typically favor fewer, faster cores.

The 4.90 GHz boost clock provides excellent single-threaded response, which is crucial for Rust's main game loop and physics calculations. The 20 MB of L3 cache helps with the game's large world data, reducing the frequency of memory accesses. The DDR5 memory support with 102.4 GB/s bandwidth ensures that the CPU can quickly access world data, though the dual-channel configuration may be a minor bottleneck in data-intensive scenes.

The CPU's PassMark physics score of 2,342 and integer math score of 65,345 indicate solid performance for game logic and world simulation. The data compression score of 302,811 and encryption score of 22,285 are less relevant for gaming but demonstrate the processor's general compute capabilities. The floating-point math score of 92,038 suggests adequate performance for Rust's rendering-related calculations that run on the CPU.
