Rust

The Intel Core i9-14900K paired with the AMD Radeon RX 580 is a lopsided combination, and the benchmark data makes that imbalance immediately clear. The CPU is a top-tier enthusiast processor with a 24-core, 32-thread Raptor Lake design that posts a Cinebench R23 multi-core score of 39,399.5 and a PassMark single-thread score of 4,697. The GPU, however, is a 2017-era Polaris 20 chip that delivers a PassMark G3D score of 8,813, which is a far cry from the CPU's capability. In Rust, this pairing produces frame rates that range from a playable 74 FPS at 1080p on Low settings to an unplayable 13 FPS at 4K on Ultra. The data shows a combos that is heavily bottlenecked by the graphics card at every resolution and settings tier, making the CPU's contribution almost irrelevant at higher loads.

How This Combo Ranks

The "Rust" benchmark results place this combo at rank 3,397 out of 3,723 tested combinations, or in the 91st percentile. That is a surprisingly low position for a system containing the Core i9-14900K, a processor that ranks in the 95th percentile against all CPUs. The culprit is the RX 580. The GPU's average benchmark score of 12,928 places it in the 53rd percentile of all graphics cards, and its performance is near the bottom of the GPU hierarchy for this game. The data shows that the combo's ranking is dragged down by the GPU, which is the limiting factor in every measured scenario.

The CPU's nearest rivals give context for the i9-14900K's potential, but the graphics card undermines it. The Intel Core i9-14900KF has an average score of 79,371, which is 0.3% higher than the 14900K's 79,097 average. Similarly, the Intel Core Ultra 9 290HX Plus scores 79,574, a 0.6% advantage. These differences are negligible in real-world gaming, but they indicate the 14900K is at the top of its class. However, when paired with the RX 580, the combo's rank in Rust is worse than nearly all other tested combinations. The data suggests that the CPU's high performance is not being utilized, as the GPU's expectation of 8,813 in PassMark G3D is a fraction of what the CPU can handle.

FAQ

Q: Is the Intel Core i9-14900K a strong processor for gaming?

It is 0.5% faster than the AMD Radeon 740M (12,870) and 0.6% faster than the AMD FirePro W5100 (12,847). These are all in the same performance tier.

Q: What is the best resolution and settings for this combo?

A: The data shows the best experience is at 1920x1080 with Low settings, which achieves an average of 74 FPS. At 1080p Medium, the average drops to 49 FPS, and at High it is 42 FPS. At 1440p, Low is 51 FPS, but at 4K Low it is 30 FPS. The data suggests that 1080p is the only resolution where a playable frame rate is achievable.

Q: Does the CPU's high core count help in Rust?

A: The data shows that the CPU's 24 cores and 32 threads are not a benefit in this specific test. The frame rates are consistently low across all settings, indicating that the GPU is the limiting component. The CPU's Cinebench R23 multi-core score of 39,399.5 is excellent, but it does not translate to higher frame rates when the GPU is running at full load.

Q: What is the overall ranking of this combo?

A: The combo ranks 3,397 out of 3,723 in Rust, placing it in the 91st percentile. This is a low ranking, primarily because the RX 580's performance is far below the CPU's capability. The GPU's G3D score of 8,813 is insufficient for the game's demands at higher resolutions.

Resolution Scaling

The measured frame rate data reveals a clear pattern of degradation as resolution increases. At 1080p Low, the average is 74 FPS. Moving to 1440p Low drops the average to 51 FPS, a 31% decrease. At 4K Low, the average further drops to 30 FPS, another 41% fall from 1440p. The same trend appears at other settings: 1080p High is 42 FPS, 1440p High is 29 FPS, and 4K High is 17 FPS. The scaling is not linear, which is typical for a GPU-bound scenario.

The performance drop between 1080p and 4K is significant. At Low settings, the FPS drops from 74 to 30, a 59% reduction. At High, it drops from 42 to 17, a 60% reduction. This indicates that the GPU is the primary limiting factor in all scenarios. The RX 580's memory bandwidth of 256.0 GB/s and 8 GB of GDDR5 memory are insufficient for the increased pixel count at 4K, leading to such a severe frame rate drop. The CPU's performance is not a factor here, as the FPS drops are directly proportional to the increase in resolution, which is a classic sign of a GPU bottleneck.

The data shows that the limiting component is the GPU. The Core i9-14900K's 6.00 GHz boost clock and 36 MB of shared L3 cache are more than sufficient for Rust, but the RX 580's 6.175 TFLOPS FP32 performance is not. At 1080p, the GPU is still the bottleneck, but the frame rates are higher due to the lower pixel count. The drop from 1080p to 4K is a 50-60% loss, which is consistent with the GPU's memory bandwidth and compute limitations.

Measured FPS Breakdown

The table of measured results shows the full picture. At 1920x1080 (Full HD), the average frame rates are:

• Low: 74 FPS
• Medium: 49 FPS (min 42, max 57)
• High: 42 FPS
• Ultra: 32 FPS

At 2560x1440 (Quad HD):

• Low: 51 FPS
• Medium: 34 FPS (min 29, max 39)
• High: 29 FPS
• Ultra: 22 FPS

At 3840x2160 (4K):

• Low: 30 FPS
• Medium: 20 FPS (min 17, max 23)
• High: 17 FPS
• Ultra: 13 FPS

These numbers reveal that the only playable setting is 1080p Low, which achieves 74 FPS. The next best is 1440p Low at 51 FPS, but that is below the typical 60 FPS target. All other configurations fall below 50 FPS, with 4K Ultra at 13 FPS being the worst. The medium settings at 1440p provides a min FPS of 29 and max 39, which is not smooth. The data indicates that the GPU is the limiting factor, with each increase in resolution or settings causing a proportional drop in performance.

Settings Recommendations

Based on the measured data, the recommended settings for this combo are Low at 1920x1080. This yields 74 FPS, which is the only configuration that consistently exceeds 60 FPS. At 1080p Medium, the average drops to 49 FPS, a 33% reduction, which is a significant compromise for visual quality. At 1440p Low, the average is 51 FPS, but this is below 60 FPS and may not be smooth enough for all players. The 1440p Medium averages 34 FPS, which is a severe drop.

At 4K, no setting is playable. The best 4K result is 30 FPS at Low, which is marginal but below the 60 FPS target. The data shows that the game is extremely GPU-bound, and the RX 580's performance is insufficient for any resolution above 1080p if the goal is a high frame rate. For a decent experience, the 1080p Low setting with 74 FPS is the only viable choice. Lowering settings to Low at 1080p provides a substantial FPS increase compared to Medium (49 FPS) or High (42 FPS). The difference between Medium and High is 7 FPS, while the jump from Low to Medium is 25 FPS.

The best experience is clearly at 1080p Low, as the 74 FPS is the only measure to hit a 60+ FPS target. If a player is willing to accept a lower frame rate, 1440p Low at 51 FPS is a reasonable compromise, but it is below 60 FPS. The 4K resolution is not playable, with the highest setting at 30 FPS.

CPU Role

The Intel Core i9-14900K is a 24-core, 32-thread processor based on "Raptor Lake" architecture. It has a base clock of 3.20 GHz and a boost clock of 6.00 GHz. Its L3 cache is 36 MB, and it supports DDR4 and DDR5 memory. In synthetic benchmarks, it achieves a Cinebench R23 multi-core score of 39,399.5 and a single-core score of 2,262.5. It also has a PassMark multi-thread score of 58,674 and a PassMark physics score of 3,140. These numbers place it in the 95th percentile of all CPUs, indicating its high performance.

However, in Rust, the CPU's performance does not translate to a high frame rate. The measured FPS data shows that the game is not limited by the CPU, but rather by the GPU. The RX 580's PassMark G3D score of 8,813 is a fraction of the CPU's capability, and the GPU's compute performance of 3,488 in PassMark GPU Compute indicates a weak GPU. The CPU's 24 cores and 32 threads are not utilized, as the game's frame rate is consistently low across all settings. For example, at 1080p, the CPU's high single-thread speed does not lift the FPS above 74 on Low settings, which is a clear sign of a GPU bottleneck.

The CPU's high boost clock and 64MB L3 cache are not the limiting factor. The game's performance is dictated by the GPU's memory bandwidth (256 GB/s) and shading units (2,304). With 32 ROPs and 144 TMUs, the RX 580's fill rate is only 42.88 GPixel/s and texture rate of 193.0 GTexel/s, which are insufficient for higher resolutions. Therefore, the CPU plays a minimal role in the measured results, and the data indicates that any modern processor would perform similarly with the RX 580 in this game. The Core i9-14900K's strengths are wasted, as the GPU is the sole performance limiter.
