Rust

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 5050 lands in the 1772nd position out of 2953 tested combos for Rust, placing it in the lower-middle tier of the database. This ranking reflects a combination where the aging six-core Comet Lake processor and the entry-level Blackwell GPU produce playable, but not exceptional, frame rates, with the system showing clear signs of being limited by both components depending on the resolution and settings applied.

How This Combo Ranks

The combo’s rank of 1772 out of 2953 places it in the 60th percentile of tested configurations, meaning roughly 40% of all recorded combos deliver higher average performance in Rust. This is a modest standing, driven by the fact that the RTX 5050 sits in the 66th percentile among all GPUs, while the i5-10400F is in the 68th percentile among all CPUs. Neither component is a standout, and the pairing does not boost the system above its individual parts.

Benchmark results indicate that the CPU’s average benchmark score of 14185 is remarkably close to its nearest rivals, with the Intel Xeon 6756E scoring 14163 (0.2% slower) and the AMD EPYC 7552 scoring 14115 (0.5% slower). On the other side, the Intel Core 7 160UL scores 14232 (0.3% faster) and the AMD Ryzen 3 7320C scores 14277 (0.6% faster). This tight cluster suggests that the i5-10400F’s processing power is neither a bottleneck nor a boon in this context; it is simply average for its class.

On the GPU side, the RTX 5050’s average benchmark score of 21035 places it directly between the AMD Radeon RX 5600 XT (20713, 1.6% slower) and the AMD Radeon RX Vega M GL (21153, 0.6% faster). The NVIDIA RTX A4000 Mobile is 1.6% ahead, while the AMD Radeon HD 8970M is 1% faster. The deltaPct values here are all within a narrow range, indicating that the RTX 5050 is squarely in the middle of its performance tier, with no significant advantage over its direct competitors.

In Rust specifically, the combination’s overall rank is dragged down by the fact that the game is notoriously CPU-intensive, and the i5-10400F’s six cores and twelve threads, while adequate, do not provide the headroom needed to push the GPU to its limits at lower resolutions. The data shows that at 1080p, the system achieves a 145 FPS average on Low settings, which is respectable, but the frame rate drops off sharply as settings increase, suggesting that the CPU is struggling to feed the GPU with enough draw calls.

GPU Role

The NVIDIA GeForce RTX 5050 is built on the Blackwell 2.0 architecture with a 5 nm process from TSMC, featuring 16,900 million transistors on a 149 mm² die. Its memory configuration consists of 8 GB of GDDR6 on a 128-bit bus, delivering 320.0 GB/s of bandwidth. The GPU’s base clock is 2317 MHz, with a boost clock of 2572 MHz, and the memory runs at 2500 MHz (20 Gbps effective).

In Rust, the GPU’s role becomes more pronounced as resolution increases. At 4K Ultra settings, the system drops to 25 FPS average, which is a clear indication that the GPU is overwhelmed by the pixel count and the game’s detailed lighting and shadow effects. Conversely, at 1080p Low settings, the 145 FPS average shows that the GPU has ample headroom, and the limiting factor shifts to the CPU.

The RTX 5050’s 8 GB of VRAM is sufficient for Rust at 1080p and 1440p, but at 4K with High or Ultra settings, the memory capacity and bandwidth become constraints. The 320.0 GB/s bandwidth is modest, and the 128-bit bus limits the amount of data that can be transferred to and from the frame buffer, which contributes to the steep performance drop at 4K Ultra.

The GPU’s benchmark scores reinforce this picture. Its Passmark G3D score of 17326 and DirectX 11 score of 150 indicate solid DirectX 11 performance, which is relevant since Rust relies heavily on this API. However, its DirectX 12 score of 66 is notably lower, suggesting that the GPU may not fully leverage newer rendering paths.

FAQ

Q: Can this system handle 4K gaming in Rust?

A: Barely, and only on Low settings. At 3840x2160 Low, the average FPS is 59, which is just playable. Medium drops to 40 FPS, High to 33 FPS, and Ultra to 25 FPS, making those presets impractical for smooth gameplay.

Q: How does the GPU’s memory bandwidth impact performance?

A: The RTX 5050’s 320.0 GB/s bandwidth on a 128-bit bus is a limiting factor at high resolutions. The data shows a significant FPS drop from 4K Low (59 FPS) to 4K High (33 FPS), indicating that the memory subsystem cannot keep up with the increased data demands.

Q: What is the CPU’s multithreaded performance relative to its rivals?

A: The i5-10400F’s Cinebench R23 multicore score is 10283. Its nearest rival, the AMD Ryzen 3 7320C, scores 14277 on average, which is 0.6% faster, while the Intel Xeon 6756E scores 14163, 0.2% slower. The differences are minimal, showing that the i5-10400F is competitive in its segment.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. On Low settings, the average FPS is 145, which is the best result across all resolutions and settings. Medium settings produce 97 FPS average, with a minimum of 83 and a maximum of 112 FPS. High settings yield 82 FPS average, while Ultra drops to 62 FPS. The gap between Low and Ultra is 83 FPS, a 57% reduction, indicating that the CPU and GPU are both stressed by higher quality presets.

Moving to 2560x1440, the performance scales down proportionally. Low settings achieve 100 FPS average, which is still smooth. Medium settings bring 67 FPS average, with a minimum of 57 and a maximum of 77 FPS. High settings produce 57 FPS average, and Ultra falls to 43 FPS. The drop from Low to Ultra is 57 FPS, a 57% reduction, mirroring the 1080p trend but at lower absolute numbers.

At 3840x2160, the system struggles to maintain playable frame rates. Low settings yield 59 FPS average, which is barely sufficient. Medium settings drop to 40 FPS average, with a minimum of 34 and a maximum of 45 FPS. High settings produce 33 FPS average, and Ultra falls to 25 FPS. The reduction from Low to Ultra is 34 FPS, a 58% drop, showing that the GPU is the primary bottleneck at this resolution.

The data shows a consistent pattern: for each resolution, the Medium preset offers the most stable frame times, as evidenced by the recorded minimum and maximum values. At 1080p Medium, the range is 83-112 FPS, while at 1440p Medium it is 57-77 FPS, and at 4K Medium it is 34-45 FPS. These ranges indicate that Medium settings provide the best balance between visual quality and frame rate consistency.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a predictable pattern, but the magnitude of the drop is telling. At Low settings, the average FPS goes from 145 at 1080p to 100 at 1440p (a 31% reduction) and then to 59 at 4K (a 41% reduction from 1440p). This steep decline at 4K suggests that the GPU is running out of memory bandwidth and fill rate.

At Medium settings, the progression is 97 FPS at 1080p, 67 FPS at 1440p (a 31% drop), and 40 FPS at 4K (a 40% drop from 1440p). The similar percentage drops across Low and Medium indicate that the GPU is the limiting factor at higher resolutions, as the CPU’s load does not scale with pixel count.

For High settings, the system achieves 82 FPS at 1080p, 57 FPS at 1440p (a 30% drop), and 33 FPS at 4K (a 42% drop from 1440p). Ultra settings follow the same trend: 62 FPS at 1080p, 43 FPS at 1440p (a 31% drop), and 25 FPS at 4K (a 42% drop). The consistent ~30% reduction from 1080p to 1440p and ~40% reduction from 1440p to 4K points squarely at the GPU’s 320.0 GB/s bandwidth as the limiting factor.

The resolution scaling data indicates that at 1080p, the CPU is the primary bottleneck, as evidenced by the relatively small FPS difference between Low (145 FPS) and Medium (97 FPS) compared to the larger drop from Medium to Ultra (62 FPS). At 4K, the GPU is clearly the constraint, with all settings producing sub-60 FPS averages, and the RTX 5050’s 8 GB VRAM and 128-bit bus struggling to handle the data throughput.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture, built on Intel’s 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz, with a 65 W TDP. The CPU features 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 12 MB of shared L3 cache. It supports DDR4 memory in a dual-channel configuration, with a memory bandwidth of 42.7 GB/s.

In Rust, the CPU’s role is significant due to the game’s heavy reliance on single-threaded performance for physics and entity updates. The i5-10400F’s 3DMark single-thread score of 688 and Cinebench R23 single-core score of 1451 indicate that its per-core performance is modest by modern standards. This explains why at 1080p Low, the system only achieves 145 FPS, as the CPU cannot process game logic fast enough to feed the GPU.

The CPU’s multithreaded performance is more robust, with a Cinebench R23 multicore score of 10283 and a Passmark multithread score of 12115. However, Rust does not scale perfectly across many cores, and the 6-core/12-thread configuration is sufficient but not ideal for the game’s demanding simulation. The data shows that at 1440p and 4K, where the GPU becomes the bottleneck, the CPU’s limitations are masked, and frame rates are more consistent.

The i5-10400F’s 42.7 GB/s memory bandwidth is another potential constraint, especially when paired with the RTX 5050 in a system that relies on system memory for assets that exceed the GPU’s 8 GB VRAM. The combination of modest single-thread performance and limited memory bandwidth means that the CPU is a secondary bottleneck in Rust, particularly at lower resolutions where the GPU has spare capacity.
