Rust

Intel Core Ultra 5 245 and Intel Arc B580 is a pairing that lands in the middle of the pack for Rust, ranking 2208 out of 2953 tested combinations. The data shows a system that can handle the game at 1080p with high refresh rates on lower presets, but struggles to maintain playable framerates at 4K on higher settings. This analysis breaks down the measured performance, the role each component plays, and the settings that deliver the best balance of visual quality and smoothness.

CPU Role, cores, clocks, and how they relate to this game's results

The Intel Core Ultra 5 245 is a 14-core, 14-thread desktop processor built on the Arrow Lake architecture and manufactured on a 3 nm process. It operates with a base clock of 3.50 GHz and can boost up to 5.10 GHz, which places it in the upper echelon of consumer CPUs. Its single-threaded performance is strong, as evidenced by a Cinebench R23 single-core score of 4648, and its multi-core capabilities are equally robust, with a Cinebench R23 multi-core score of 32924. The processor also holds a 90th percentile ranking against all CPUs, indicating it outperforms the vast majority of processors on the market.

In Rust, the CPU's role is significant because the game is known for heavy simulation and entity processing. The data suggests the Ultra 5 245 handles this workload well, as the system achieves 133 FPS at 1080p on Low settings, which is a scenario where the GPU is less burdened and the CPU's ability to feed frames becomes the limiting factor. The processor's 24 MB of shared L3 cache and dual-channel DDR5 memory support (with 102.4 GB/s bandwidth) contribute to its responsiveness in such scenarios. The 14 threads are not hyperthreaded, but the physical cores provide consistent performance for the game's typically single-thread-heavy physics calculations.

Comparing to its nearest rivals, the Ultra 5 245 sits within a tight performance band. It is 0.4% slower than the AMD Ryzen 7 PRO 5755G and 0.5% slower than the AMD Ryzen 9 7900 in average benchmark score. Conversely, it is 0.6% faster than the Intel Xeon Gold 5318H and 0.8% faster than the Intel Core i5-14600K. These deltas are marginal, meaning in real-world gaming, the differences would be negligible. The data indicates the CPU is a capable partner for the Arc B580, never appearing to bottleneck the GPU at lower resolutions, and its performance headroom is evident in the 1080p Low result where it pushes past 130 FPS.

FAQ, 4-6 Q&A pairs answerable from FACT PACK data

Q: How does the Core Ultra 5 245 compare to the Intel Core i5-14600K?

A: The Core Ultra 5 245 has an average benchmark score of 48995, which is 0.8% higher than the Intel Core i5-14600K's score of 48618. This indicates a negligible performance difference between the two processors in synthetic tests, with the Ultra 5 245 holding a slight edge.

Q: Is the Arc B580's 12 GB of VRAM sufficient for Rust at 4K?

A: The GPU has 12 GB of GDDR6 memory on a 192-bit bus with 456.0 GB/s bandwidth. The measured data shows that at 3840x2160 on Ultra settings, the system only averages 23 FPS. This suggests the GPU's compute capabilities, rather than VRAM capacity, are the primary constraint at this resolution, as the memory size is ample for the game's textures.

Q: What is the best resolution for high refresh rate gaming with this combo?

A: At 1920x1080 on Low settings, the system achieves 133 FPS, which is the highest measured average in the data. This is the only configuration that breaks the 120 FPS threshold, making it the target for competitive or high-refresh-rate play. At 1440p, the best average FPS is 92 on Low, which is still playable but not as fluid.

Q: Does the Arc B580 outperform the RTX 2080 in Rust?

A: The Arc B580 has an average benchmark score of 23021, which is 0.6% higher than the NVIDIA GeForce RTX 2080's score of 22895. This indicates the Arc B580 is slightly faster in general GPU benchmarks, but the measured FPS in Rust will still depend on the specific settings and resolution used.

Q: Why does the FPS drop so significantly between Low and Ultra settings at 4K?

A: At 3840x2160, the average FPS drops from 54 on Low to 23 on Ultra, a reduction of more than half. This is due to the increased pixel count and the higher graphical load on the GPU's shading units, TMUs, and ROPs, which are tasked with rendering more complex effects and geometry at that resolution.

Q: What is the CPU's single-threaded performance relative to its multi-threaded performance?

A: The CPU scores 4648 in Cinebench R23 single-core and 32924 in multi-core. The multi-core score is roughly seven times higher, which reflects the scaling across its 14 cores. For Rust, the single-core strength is more relevant, as the game often relies on one or two threads for core simulation logic.

Resolution Scaling, how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, which helps identify the system's bottleneck. Starting at 1920x1080 on Low settings, the system produces 133 FPS. Moving to 2560x1440 on the same settings drops the average to 92 FPS, a reduction of approximately 31%. At 3840x2160, the average falls further to 54 FPS, which is a 59% drop from the 1080p result. This scaling is not linear, indicating that the GPU is becoming increasingly stressed as the pixel count grows.

On Medium settings, the trend is similar but with lower absolute numbers: 89 FPS at 1080p, 61 FPS at 1440p, and 36 FPS at 4K. The percentage drops are consistent, suggesting a GPU-bound scenario at higher resolutions. The Ultra settings tell the most telling story: 57 FPS at 1080p, 39 FPS at 1440p, and 23 FPS at 4K. The 4K Ultra result is barely above a slideshow, which strongly suggests the Arc B580's raw compute power is the limiting factor, not the CPU. The CPU's performance is relatively constant across resolutions, so the FPS decline can be attributed to the GPU's fill rate and pixel throughput capabilities.

The data implies that at 1080p, the system is somewhat balanced, with the CPU capable of driving high frame rates and the GPU keeping pace. However, at 1440p and especially 4K, the GPU becomes the clear bottleneck. The Arc B580's 13.67 TFLOPS of FP32 performance and 213.6 GPixel/s pixel rate are insufficient to maintain high frame rates at these higher resolutions, particularly with demanding presets. For users targeting 1440p or 4K, the measurements indicate that lower settings are necessary to achieve acceptable performance.

Measured FPS Breakdown, resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the system delivers 133 FPS on Low, 89 FPS on Medium, 75 FPS on High, and 57 FPS on Ultra. The Medium preset shows a minimum FPS of 76 and a maximum of 103, indicating some frame pacing variance, while the other presets do not have min/max values listed. This range suggests that 1080p Medium is a viable option for a smooth experience, though it sacrifices about a third of the FPS compared to Low.

At 2560x1440, the scores drop to 92 FPS on Low, 61 FPS on Medium, 52 FPS on High, and 39 FPS on Ultra. The Medium preset again shows variance with a minimum of 52 and a maximum of 71 FPS. The jump from Low to Medium at this resolution is a 34% reduction in FPS, which is substantial. High and Ultra further reduce performance, making them less attractive for competitive play but potentially acceptable for slower-paced exploration.

At 3840x2160, the system averages 54 FPS on Low, 36 FPS on Medium, 31 FPS on High, and 23 FPS on Ultra. The Medium preset has a minimum of 31 and a maximum of 42 FPS. These numbers are challenging for a game like Rust, where sudden action and complex environments demand consistent frame delivery. Even the Low preset at 54 FPS is barely adequate, and the Ultra preset at 23 FPS is essentially unplayable for most users. The data clearly shows that this combo is not suited for 4K gaming beyond the lowest settings.

GPU Role, VRAM, clocks, and how they relate to this game's results

The Intel Arc B580 is built on the Xe2-HPG architecture, codenamed Battlemage, and manufactured on a 5 nm process. It features 2560 shading units, 160 TMUs, and 80 ROPs, with a base and boost clock of 2670 MHz. Its memory subsystem includes 12 GB of GDDR6 on a 192-bit bus, providing 456.0 GB/s of bandwidth. The GPU's 13.67 TFLOPS of FP32 compute and 427.2 GTexel/s texture rate are solid mid-range figures, positioning it at the 68th percentile against all GPUs.

In Rust, the GPU's role becomes more critical as resolution and settings increase. At 1080p Low, the GPU has enough headroom to push 133 FPS, but at 4K Ultra, it drops to 23 FPS. This indicates that the card's pixel fill rate and compute capabilities are insufficient for the demands of higher resolutions with advanced effects. The 12 GB VRAM is not the constraining factor, as Rust's textures are unlikely to exceed this capacity, even at 4K. Instead, the bottleneck lies in the GPU's raw throughput.

The Arc B580's nearest rivals in average benchmark score are the AMD Radeon RX 580 2048SP, which it trails by 0.2%, and the NVIDIA GeForce RTX 2080, which it leads by 0.6%. It also sits 0.7% behind the RTX 3080 and 1% ahead of the NVIDIA P106-100. These deltas are small, suggesting the Arc B580 is a consistent performer in its class. For Rust specifically, the measured FPS at 1080p suggests the card is well-suited for 1080p gaming, but its performance at 1440p and 4K is limited, requiring users to dial back settings to maintain playable frame rates.

Settings Recommendations, which preset gives the best experience per the measured rows

The measured FPS data provides clear guidance on which settings preset offers the best experience at each resolution. At 1920x1080, the Low preset delivers 133 FPS, which is ideal for high-refresh-rate monitors (120Hz or above). However, the Medium preset at 89 FPS is a strong alternative, offering better visual quality while still maintaining a smooth experience on a standard 60Hz display. The High preset at 75 FPS is also viable, but the Ultra preset at 57 FPS introduces a noticeable drop that may not justify the visual gains.

At 2560x1440, the Low preset at 92 FPS is the best choice for maintaining high frame rates, especially for users with 144Hz monitors. The Medium preset at 61 FPS is acceptable for 60Hz displays, but the variance between 52 and 71 FPS could cause occasional stutters. The High and Ultra presets, at 52 and 39 FPS respectively, are less recommended unless the user prioritizes visuals over smoothness, but they fall below the 60 FPS threshold that most consider the minimum for a comfortable experience.

At 3840x2160, none of the presets achieve a solid 60 FPS. The Low preset at 54 FPS is the closest, and it is the only one that approaches playability. The Medium preset at 36 FPS and the High preset at 31 FPS are borderline, while the Ultra preset at 23 FPS is not recommended for any gameplay scenario. For 4K users, the data suggests staying on Low settings is the only way to get a semi-fluid experience, and even then, users should be prepared for occasional dips. For the best overall balance, the Medium preset at 1080p or the Low preset at 1440p offers the most consistent performance relative to visual quality, based on the measured average and min/max FPS values.
