Rust

The AMD Ryzen 9 9900X paired with the Intel Arc B370 ranks 2710th out of 2953 tested combos in Rust, placing it in the bottom 8% of all systems tested. This is a profoundly lopsided pairing: the CPU is a top-tier 12-core desktop processor, while the GPU sits at the 5th percentile of all tested graphics cards. The benchmark data shows that this combo is entirely GPU-bound, with the Arc B370 acting as the sole bottleneck across all resolutions and settings. For a survival game like Rust, where large bases and server populations demand consistent frame pacing, the results are clear: this combination is only suitable for low-resolution, low-detail play, and even then, the margins are thin.

How This Combo Ranks

The combo's rank of 2710 out of 2953 tested combinations is a clear signal of systemic imbalance. Out of every 100 tested combos, this one outperforms only about 8 of them. This is not a ranking driven by the Ryzen 9 9900X, which alone sits at the 92nd percentile among all CPUs; rather, it is dragged down by the Intel Arc B370, which sits at the 5th percentile among all GPUs. The data indicates that in Rust, the GPU is the overwhelming performance limiter, and the CPU's capabilities are largely left untapped.

When examining the CPU's nearest rivals, the Ryzen 9 9900X shows a negligible performance delta, with the AMD EPYC 9015 just 0.1% slower and the AMD EPYC 7313 just 0.2% faster. The Intel Core i9-14900 is 1.1% faster, and the Intel Xeon Platinum 8260M is 1.4% faster. These tiny margins confirm that the CPU is not the differentiator here; swapping between these processors would not meaningfully change the Rust experience with this GPU. The bottleneck is so severe that the combo's ranking is essentially a reflection of the GPU's standalone performance, which the 3DMark Steel Nomad DX12 score of 1184 confirms—a figure that places it just 0.2% behind the ATI Mobility Radeon HD 5570 and 0.5% behind the ATI Radeon HD 5770.

In practical terms, this ranking means the system is not viable for modern Rust play at high fidelity. The 16 FPS average at 4K High and the 30 FPS at 1080p Ultra are indicative of a GPU that is being overwhelmed by the game's rendering demands. The combo's position is a cautionary tale about pairing a high-end CPU with an entry-level integrated graphics solution.

GPU Role

The Intel Arc B370 is not a discrete card but an integrated graphics processor (IGP) based on the Xe3-LPG architecture and the Panther Lake chip. It operates with a base clock of 300 MHz and a boost clock of 2400 MHz, which is a wide frequency range that allows it to scale under load. However, its memory configuration is "System Shared," meaning it relies on the system's DDR5 RAM, and its bandwidth is "System Dependent." This is a critical limitation for a game like Rust, which is memory-bandwidth sensitive.

The GPU's raw specs are modest: 1280 shading units, 40 texture mapping units, and 20 raster output pipelines. It also includes 10 ray tracing cores, though Rust does not heavily utilize ray tracing. The pixel rate is 48.00 GPixel/s and the texture rate is 96.00 GTexel/s, with FP32 performance at 6.144 TFLOPS. These numbers place it in the same performance class as legacy discrete cards like the ATI Radeon HD 5770, which is exactly what the nearest rival data shows. The GPU's 25 W TDP and IGP slot width reinforce that this is a low-power, integrated solution not designed for gaming workloads.

The benchmark results show this GPU is the limiting factor. At 1080p Low, the combo hits 69 FPS average, but dropping to 1080p Ultra reduces that to 30 FPS—a 56% performance penalty. This steep drop-off across settings is typical of a GPU that lacks the raw fill rate and memory bandwidth to handle higher-detail geometry and textures. The GPU's VRAM is also "System Shared," which means it competes with the CPU for memory bandwidth, further exacerbating the bottleneck in a game with large, persistent worlds.

Resolution Scaling

The measured FPS data reveals a predictable scaling pattern that isolates the GPU as the bottleneck. Moving from 1080p to 1440p to 4K, the average FPS drops consistently across all settings, with the GPU struggling to maintain playable framerates at higher pixel counts.

At High settings, the combo averages 39 FPS at 1080p, 27 FPS at 1440p, and 16 FPS at 4K. This is a 31% drop from 1080p to 1440p, and a further 41% drop from 1440p to 4K. At Low settings, the numbers are 69 FPS at 1080p, 48 FPS at 1440p, and 28 FPS at 4K—a 30% drop and a 42% drop, respectively. The scaling is remarkably linear, indicating that the GPU's fill rate and memory bandwidth are being saturated at each resolution step.

The Medium settings show similar behavior: 46 FPS at 1080p, 32 FPS at 1440p, and 19 FPS at 4K. The Ultra preset is the most punishing, with 30 FPS at 1080p, 20 FPS at 1440p, and 12 FPS at 4K. The fact that even 1080p Ultra cannot maintain 30 FPS is significant; it proves that the GPU is the limiting component, not the CPU. If the CPU were the bottleneck, we would expect to see similar FPS numbers across resolutions, but the data shows a clear resolution-dependent decline.

The implication is clear: this combo is only suitable for 1080p gaming, and even then, only at Low or Medium settings. The jump to 1440p and 4K is not viable for competitive or immersive play, as the FPS drops below 30 at almost every setting above Low. The data suggests that users should either lower their resolution or significantly reduce graphical fidelity to achieve a playable experience.

FAQ

Q: Is this combo capable of running Rust at 4K?

A: The data shows 4K performance is poor across all settings. Average FPS ranges from 12 at Ultra to 28 at Low, with Medium averaging 19 FPS. These numbers are below the threshold for smooth gameplay, indicating the GPU cannot handle the pixel count.

Q: What is the best settings preset for this combo at 1080p?

A: At 1080p, the Low preset yields 69 FPS average, which is the only setting that approaches a smooth experience. Medium averages 46 FPS, while High averages 39 FPS and Ultra drops to 30 FPS. The data suggests Low is the only viable option for consistent frame rates.

Q: How does the Ryzen 9 9900X compare to its nearest rivals in CPU benchmarks?

A: The Ryzen 9 9900X has an average benchmark score of 57498, placing it at the 92nd percentile. Its nearest rival, the AMD EPYC 9015, scores 57555, which is 0.1% faster. The Intel Core i9-14900 is 1.1% faster, and the Intel Xeon Platinum 8260M is 1.4% faster.

Q: Is the Intel Arc B370 a discrete graphics card?

A: No, it is an integrated graphics processor (IGP) with a 25 W TDP and a slot width of IGP. It uses System Shared memory, meaning it relies on the system's DDR5 RAM rather than dedicated VRAM.

Q: What is the FPS drop from 1080p to 1440p at High settings?

A: The combo averages 39 FPS at 1080p High and 27 FPS at 1440p High, a drop of 12 FPS or approximately 31%. This indicates the GPU is the limiting factor as resolution increases.

Q: Does the CPU's 12-core configuration help in Rust?

A: The Ryzen 9 9900X has 12 cores and 24 threads with a boost clock of 5.60 GHz, but the benchmark data shows the GPU is the bottleneck. The FPS remains low even at 1080p, suggesting the CPU's multi-threaded power is not being utilized due to the GPU's limitations.

Measured FPS Breakdown

The measured FPS data provides a precise picture of the combo's performance across resolutions and settings. All figures below are average FPS unless otherwise noted.

1920x1080:

• Low: 69 FPS
• Medium: 46 FPS (min 39, max 53)
• High: 39 FPS
• Ultra: 30 FPS

2560x1440:

• Low: 48 FPS
• Medium: 32 FPS (min 27, max 37)
• High: 27 FPS
• Ultra: 20 FPS

3840x2160:

• Low: 28 FPS
• Medium: 19 FPS (min 16, max 22)
• High: 16 FPS
• Ultra: 12 FPS

The 1080p Low result of 69 FPS is the only configuration that achieves a fluid frame rate suitable for fast-paced gameplay. The drop from 69 FPS at 1080p Low to 48 FPS at 1440p Low represents a 30% reduction, and the further drop to 28 FPS at 4K Low is another 42% reduction. This scaling pattern is consistent with a GPU that is running out of memory bandwidth and shading power.

At Medium settings, the minimum FPS values are telling: 39 FPS at 1080p, 27 FPS at 1440p, and 16 FPS at 4K. These minimums are close to the averages, suggesting frame times are relatively stable but at an unplayable level for higher resolutions. The Ultra preset is the worst case, with averages of 30 FPS at 1080p and 12 FPS at 4K, making it unsuitable for any resolution above 720p in practice.

CPU Role

The AMD Ryzen 9 9900X is a 12-core, 24-thread processor based on the Zen 5 architecture (Granite Ridge) and built on a 4 nm TSMC process. It has a base clock of 4.40 GHz and a boost clock of 5.60 GHz, with a 120 W TDP. The CPU supports DDR5 memory with a dual-channel bus and has 64 MB of L3 cache, plus 1 MB of L2 cache per core and 80 KB of L1 cache per core. The 3DMark benchmarks show strong multi-threaded performance: 12552 in 16-thread, 13929 in max-thread, and 9114 in 8-thread tests. Single-thread performance is also solid, with a 3DMark single-thread score of 1286 and a Cinebench R23 single-core score of 2253.

In Rust, the CPU's role is to manage server-side simulation, entity updates, and physics calculations. The Ryzen 9 9900X is more than capable of handling these tasks, as evidenced by its Cinebench R23 multi-core score of 32172 and Geekbench multi-core score of 22174. However, the measured FPS in Rust does not reflect this capability. The fact that the FPS scales almost linearly with resolution and settings indicates that the CPU is not the limiting factor; rather, the GPU is failing to keep up with the CPU's output.

The data shows that the CPU's nearest rivals—the AMD EPYC 9015, AMD EPYC 7313, Intel Core i9-14900, and Intel Xeon Platinum 8260M—all perform within 1.4% of the Ryzen 9 9900X on average benchmark scores. This tight grouping suggests that any of these CPUs would yield similar Rust performance when paired with the Arc B370. Conversely, the GPU's nearest rivals—the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, and AMD FirePro M2000—are all legacy parts from over a decade ago, underscoring the GPU's outdated performance level.

The conclusion is unavoidable: the Ryzen 9 9900X is wasted in this pairing for Rust. The CPU's 24 threads and high boost clock are irrelevant when the GPU cannot render frames fast enough. For users considering this combo, the data suggests that the CPU is not the issue; the GPU must be upgraded to achieve playable performance at higher resolutions and settings.
