Rust

Intel Core Ultra 5 245 paired with the AMD Radeon RX 7800 XT delivers a fundamentally balanced 1080p and 1440p experience in Rust, with 4K remaining the only resolution where the combination struggles to maintain high refresh rates. The measured frames per second (FPS) data across four quality presets and three resolutions reveals a system where the GPU becomes the primary constraint at higher pixel counts, while the CPU’s 14 cores and 5.10 GHz boost clock provide ample headroom for the game’s simulation-heavy workload.

Resolution Scaling

The FPS drop from 1920x1080 to 3840x2160 is steep and consistent across all settings, indicating that the Radeon RX 7800 XT is the limiting factor as pixel count rises. At Low settings, the average frame rate falls from 203 FPS at 1080p to 140 FPS at 1440p, then to 83 FPS at 4K — a cumulative reduction of 59% from the baseline. This scaling pattern is typical of a GPU-bound scenario, where the 624.1 GB/s memory bandwidth and 16 GB of GDDR6 VRAM are taxed heavily by the higher resolution’s increased fill rate demands.

The Medium preset shows a similar trajectory: 137 FPS at 1080p, 94 FPS at 1440p, and 55 FPS at 4K. The 4K result is particularly telling, as it falls below the 60 FPS threshold that most players consider the minimum for smooth gameplay. The High preset follows suit with 115 FPS at 1080p, 79 FPS at 1440p, and 47 FPS at 4K. The Ultra preset is the most demanding, dropping from 88 FPS at 1080p to 60 FPS at 1440p and finally to 36 FPS at 4K — a 59% loss from 1080p to 4K, mirroring the Low preset’s proportional decline.

The fact that the percentage drop from 1080p to 4K is nearly identical across Low (59%) and Ultra (59%) presets suggests that resolution scaling is independent of quality settings. This is a hallmark of GPU-bound performance, where the rendering resolution dictates the workload more than the specific graphical features enabled. At 1080p, the CPU’s 3.50 GHz base clock and 24 MB of shared L3 cache are sufficient to feed the GPU, but at 4K, the RX 7800 XT’s 37.32 TFLOPS of FP32 compute becomes the bottleneck, capping average FPS below playable thresholds on all presets except Low.

CPU Role

The Intel Core Ultra 5 245 brings 14 cores and 14 threads to the Rust benchmark, a configuration that aligns well with the game’s known tendency to utilize multiple threads for world simulation and entity processing. The CPU’s 5.10 GHz boost clock is the standout specification, allowing single-threaded tasks — which Rust relies on for physics and netcode — to execute quickly. The 3 nm process node from TSMC and Arrow Lake architecture contribute to a 90th percentile ranking among all CPUs in the database, though the benchmark scores place it in close competition with several rivals.

The Cinebench R23 scores of 32924 multi-core and 4648 single-core provide context for the CPU’s capability. The single-core score is particularly relevant for Rust, as the game’s main thread often becomes the limiting factor in CPU-bound scenarios. The PassMark single-thread score of 4394 corroborates this strength, suggesting that the Core Ultra 5 245 can handle the game’s serial portions without becoming a bottleneck at 1080p, where the GPU is already saturated.

Comparing to nearest rivals, the CPU’s average benchmark score of 48995 is nearly identical to the AMD Ryzen 7 PRO 5755G (49196, -0.4% delta) and AMD Ryzen 9 7900 (49228, -0.5% delta). It edges out the Intel Xeon Gold 5318H (48698, +0.6% delta) and the Intel Core i5-14600K (48618, +0.8% delta). This tight grouping suggests that the Core Ultra 5 245’s performance is competitive with these alternatives, though none of these rivals are tested in Rust specifically. The 14 threads, while fewer than the 20 threads on the Ryzen 9 7900, do not appear to hamper the CPU’s ability to drive the RX 7800 XT, as evidenced by the 203 FPS average at 1080p Low.

The 65 W TDP and dual-channel DDR5 memory support (102.4 GB/s bandwidth) indicate a power-efficient design that still delivers adequate memory throughput for gaming. The lack of an unlocked multiplier means overclocking is not an option, but the stock boost clock of 5.10 GHz is already high enough to prevent CPU-induced frame dips in the measured data. At 1440p and 4K, the CPU’s role diminishes further, as the GPU-bound nature of higher resolutions means the processor is rarely waiting on data.

GPU Role

The AMD Radeon RX 7800 XT is the star of this combination, and its specifications directly explain the measured FPS patterns. With 16 GB of GDDR6 VRAM on a 256-bit bus, the memory configuration provides 624.1 GB/s of bandwidth — ample for Rust’s large textures and open-world streaming at 4K, where the Low preset still manages 83 FPS. The GPU’s boost clock of 2430 MHz and 3840 shading units deliver 37.32 TFLOPS of FP32 compute, which drives the frame rates seen across all settings.

The GPU’s 51st percentile ranking among all GPUs in the database is a crucial data point. This places it in the middle of the pack, and the nearest rivals — NVIDIA GeForce GTX 1660 (11680, -0.5% delta) and AMD Radeon RX 6500 XT (11842, -1.8% delta) — are significantly less powerful in practice, despite similar average benchmark scores. The RX 7800 XT’s 24176 PassMark G3D score and 13473 GPU compute score highlight its rasterization strength, which is what Rust primarily relies on, given the game’s lack of demanding ray tracing features.

The 4K Ultra result of 36 FPS is the clearest indicator of the GPU’s limits. At this setting, the combination of higher pixel count and maximum quality settings overwhelms the 240 TMUs and 96 ROPs, causing the average to dip below 40 FPS. The Medium preset at 4K shows a minimum FPS of 47, which is just above the High preset’s 4K average of 47, suggesting that the GPU is hitting a hard performance wall around this range. The 2x 8-pin power connectors and 263 W TDP confirm that this GPU is designed for high performance, but the data shows it is best suited for 1080p and 1440p gaming in Rust.

The GPU’s 1295 MHz base clock and 2124 MHz game clock provide a stable foundation, with the boost clock of 2430 MHz allowing for bursts of performance when thermal headroom permits. The 5 nm process node and RDNA 3.0 architecture are modern, but the 51st percentile ranking indicates that the RX 7800 XT is not a top-tier card — it is a mid-range offering that excels at 1080p and handles 1440p well, but struggles to maintain 60 FPS at 4K on anything above Low settings.

FAQ

Q: Is the GPU the bottleneck at 1080p or 4K?

A: At 1080p, the GPU is the primary bottleneck, as evidenced by the 59% FPS drop from Low to Ultra (203 to 88 FPS). At 4K, the GPU is even more clearly the limiting factor, with the same 59% drop from Low to Ultra (83 to 36 FPS), while the CPU’s high single-core score prevents it from being the constraint.

Q: What is the minimum FPS recorded for this combo in Rust?

A: The lowest minimum FPS recorded is 47, which occurs at 4K with Medium settings. At 1440p Medium, the minimum is 80 FPS, and at 1080p Medium, it is 116 FPS. The min FPS values are only provided for Medium settings across all resolutions.

Q: How does the GPU’s ranking compare to its benchmark rivals?

A: The RX 7800 XT ranks in the 51st percentile of all GPUs. Its average benchmark score of 11627 is nearly identical to the NVIDIA GeForce GTX 1660 (11680), but the RX 7800 XT’s 16 GB of VRAM and higher compute throughput make it far more capable in modern games like Rust.

How This Combo Ranks

The combo ranks 882nd out of 2953 tested combinations in Rust, placing it in the 70th percentile of all systems evaluated. This is a respectable position, though not top-tier, reflecting the mid-range nature of both the CPU and GPU. The ranking suggests that while this combination delivers solid frame rates at 1080p and 1440p, there are many other systems that outperform it, particularly those with higher-end GPUs or CPUs with more single-threaded performance.

The 882nd rank out of 2953 combos means that roughly 30% of tested systems achieve better performance in Rust. This is consistent with the GPU’s 51st percentile ranking and the CPU’s 90th percentile ranking — the CPU is strong, but the GPU holds the system back from reaching higher ranks. The data indicates that pairing the Core Ultra 5 245 with a more powerful GPU would likely improve the rank significantly, as the CPU has headroom to drive higher frame rates.

In the context of the measured FPS, the combo’s rank is justified by the 4K results, where even Medium settings fail to reach 60 FPS. At 1080p, the combo performs admirably, with 203 FPS on Low and 115 FPS on High, which would place it in the upper echelon for competitive play. However, the 4K Ultra result of 36 FPS drags the overall ranking down, as many other combos can achieve higher frame rates at that resolution.

Settings Recommendations

For the best experience based on the measured data, the Medium preset at 2560x1440 is the recommended configuration. It delivers an average of 94 FPS, which is well above the 60 FPS threshold for smooth gameplay, and the minimum FPS of 80 ensures that frame dips are rare. The High preset at 1440p (79 FPS) is also viable, but the Medium preset offers a better balance of visual quality and performance, with a 19% FPS increase over High.

At 1920x1080, the High preset is the best choice, offering 115 FPS average. The Ultra preset at 1080p (88 FPS) is playable but the visual difference between High and Ultra is not worth the 23% performance penalty. The Low preset at 1080p (203 FPS) is unnecessary for most players, as 115 FPS is already far above the refresh rate of most monitors. For competitive players seeking maximum frame rates, the Low preset at 1080p is the only option that exceeds 200 FPS.

At 4K, the Low preset is the only playable option, with 83 FPS average. The Medium preset at 4K (55 FPS) is borderline, and the minimum FPS of 47 suggests that it will drop below 60 FPS during intense moments. The High and Ultra presets at 4K (47 and 36 FPS, respectively) are not recommended for anything other than screenshot purposes. The data clearly shows that this combo is not designed for 4K gaming in Rust, and players should stick to 1440p or 1080p for the best experience.

Measured FPS Breakdown

At 1920x1080, the measured average FPS across settings is as follows: Low delivers 203 FPS, Medium delivers 137 FPS (with a minimum of 116 and maximum of 157), High delivers 115 FPS, and Ultra delivers 88 FPS. The spread from Low to Ultra is 115 FPS, a 57% reduction, which is substantial but expected given the graphical fidelity differences.

At 2560x1440, the averages are: Low at 140 FPS, Medium at 94 FPS (minimum 80, maximum 108), High at 79 FPS, and Ultra at 60 FPS. The drop from 1080p to 1440p is consistent across settings, with Low falling by 31%, Medium by 31%, High by 31%, and Ultra by 32%. This uniformity reinforces the GPU-bound nature of the performance.

At 3840x2160, the averages are: Low at 83 FPS, Medium at 55 FPS (minimum 47, maximum 64), High at 47 FPS, and Ultra at 36 FPS. The drop from 1440p to 4K is more severe, with Low falling by 41%, Medium by 41%, High by 41%, and Ultra by 40%. This accelerated decline at 4K indicates that the GPU is hitting a memory bandwidth or compute limit, as the pixel count quadruples from 1080p.

The only settings with min and max FPS data are Medium across all three resolutions. At 1080p, the range is 116 to 157 FPS; at 1440p, it is 80 to 108 FPS; and at 4K, it is 47 to 64 FPS. These ranges show that the frame pacing is consistent, with the gap between min and max shrinking at higher resolutions (41 FPS at 1080p, 28 FPS at 1440p, 17 FPS at 4K), which is a sign of GPU saturation reducing frame time variance. The absence of min/max data for other settings means only averages are available for comparison, but the Medium preset provides the most comprehensive picture of the combo’s frame delivery.
