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

The Intel Core i5-12400 brings 6 cores and 12 threads to Rust, running at a 2.50 GHz base clock and boosting to 4.40 GHz. This Alder Lake-S part, built on Intel's 10 nm process, sits in the 77th percentile of all CPUs tested in the database, with an average benchmark score of 19850. Its nearest rivals tell a story of tight competition: the Intel Core i7-9700 scores 19831 (just 0.1% behind), the Intel Core i7-8700 scores 19894 (0.2% ahead), and the Intel Core i5-11600K scores 19771 (0.4% behind). The AMD Ryzen Threadripper PRO 5995WX, a much more expensive workstation part, is only 0.4% ahead at 19928 — a striking result that suggests the i5-12400's per-core performance is exceptional, even if its 18 MB shared L3 cache and dual-channel DDR4/DDR5 memory support don't match HEDT territory.

In Rust, the CPU's role is substantial. The game's simulation and world-streaming systems are known to be thread-hungry, and the data reflects this. At 1080p Low, the combo hits 114 FPS, but at 1080p Ultra it drops to 49.6 FPS — a 56.5% reduction that points to both CPU and GPU load increasing with settings. The Cinebench R23 multicore score of 15935 and single-core score of 2249 indicate strong raw throughput, while the PassMark multithread score of 18747 and single-thread score of 3456 reinforce that this chip can feed a mid-range GPU without becoming a bottleneck in most scenarios. However, the 3DMark 16-thread score of 5873 versus the 8-thread score of 4745 suggests scaling beyond 8 threads is modest, which aligns with Rust's typical behavior of using a handful of heavily loaded threads. The 4-thread score of 3012 and 2-thread score of 1692 show that even at low thread counts, the chip holds its own, which is critical for Rust's often single-thread-bound physics and entity update loops.

# How This Combo Ranks

This pairing of the Intel Core i5-12400 with the NVIDIA GeForce GTX 1070 ranks 1450 out of 1717 tested combos in Rust. That places it in the bottom 15.5% of all combinations in the database, which is a sobering context for a CPU that individually sits in the 77th percentile. The discrepancy is telling: the CPU is capable, but the GPU holds this combo back significantly. The GTX 1070's individual percentile is 51, meaning it sits exactly at the median of all GPUs tested, and its average benchmark score of 12331 is modest. The nearest GPU rivals — the NVIDIA Quadro K4200 (12241, 0.7% behind), GeForce GTX 880M (12490, 1.3% ahead), GeForce GTX 1650 SUPER (12504, 1.4% ahead), and Tesla K20Xm (12547, 1.7% ahead) — show that the GTX 1070 is in a dense pack of similar-performance cards, none of which are modern high-end parts.

The low combo rank suggests that in Rust, this pairing is not delivering the experience the CPU alone could support. At 1080p Low, the 114 FPS is respectable, but the GPU's Pascal architecture (16 nm, 7,200 million transistors on a 314 mm² die) becomes the limiting factor as settings rise. The data implies that users with this combo are leaving performance on the table — a stronger GPU would likely shift the combo rank dramatically upward, given the CPU's headroom. Yet the rank also reflects that many tested combos use faster GPUs or newer CPUs, and this mid-range pairing is simply outclassed in the aggregate.

# Resolution Scaling

The FPS drop from 1080p to 4K is stark and reveals the GPU as the primary constraint. At High settings, the combo delivers 61.6 FPS at 1080p, drops to 46.7 FPS at 1440p (a 24.2% reduction), and collapses to 25 FPS at 4K (a 59.4% reduction from 1080p). This scaling pattern is classic GPU-bound behavior: as pixel count rises, the GTX 1070's 8 GB of GDDR5 memory and 256.3 GB/s bandwidth struggle to keep up. The 4K High result of 25 FPS is borderline unplayable, while 4K Ultra at 17.8 FPS is a slideshow.

At Low settings, the scaling is less severe but still pronounced: 114 FPS at 1080p, 79.3 FPS at 1440p (a 30.4% drop), and 43.4 FPS at 4K (a 61.9% drop from 1080p). The fact that 4K Low only reaches 43.4 FPS, despite the CPU's strength, confirms that the GPU's pixel throughput (107.7 GPixel/s) and texture rate (202.0 GTexel/s) are the hard ceiling. The 150 W TDP and dual-slot cooler are typical for this class, but the architecture's age shows. Interestingly, the 1080p to 1440p drop at Low (30.4%) is larger than the 1080p to 1440p drop at High (24.2%), suggesting that at Low settings, the CPU is still feeding enough frames to push the GPU harder relative to its capacity. At High settings, the GPU is already saturated at 1080p, so the relative drop to 1440p is smaller. This nuance points to a system where the balance shifts subtly across the settings spectrum.

# Measured FPS Breakdown

At 1920x1080, the combo shows its best face. Low settings produce 114 FPS, which is smooth for a survival game with frequent render-worthy events. Medium settings drop to 78.8 FPS, High to 61.6 FPS, and Ultra to 49.6 FPS. The gap between Low and Medium is 35.2 FPS (30.9%), while the gap between High and Ultra is 12 FPS (19.5%). This suggests that the Medium preset offers a sweet spot, retaining most of the performance headroom while improving visual fidelity over Low. The 1080p data also shows that the GPU can push past 60 FPS at High, which many players would consider the minimum acceptable threshold for a competitive survival experience.

At 2560x1440, the picture dims. Low settings yield 79.3 FPS, which is still playable, but Medium drops to 52.7 FPS, High to 46.7 FPS, and Ultra to 30.9 FPS. The 1440p Low result is 30.4% lower than 1080p Low, confirming that resolution scaling hits this GPU hard. The 1440p Ultra result of 30.9 FPS is below the 60 FPS target, meaning users must choose between resolution and settings. At 3840x2160, only Low settings approach playability at 43.4 FPS. Medium delivers 28.5 FPS, High 25 FPS, and Ultra 17.8 FPS. The 4K Ultra result is 84.4% lower than 1080p Low, underscoring the GPU's inability to handle 4K in this title under any realistic scenario.

# GPU Role

The NVIDIA GeForce GTX 1070, based on the GP104 chip and Pascal architecture, is a 16 nm part with 7,200 million transistors on a 314 mm² die. Its base clock of 1506 MHz and boost clock of 1683 MHz are paired with 8 GB of GDDR5 memory on a 256-bit bus, yielding 256.3 GB/s of bandwidth. The memory clock runs at 2002 MHz (8 Gbps effective), which was competitive in its era but is now modest. The card has 1920 shading units, 120 texture mapping units, and 64 ROPs, delivering 6.463 TFLOPS of FP32 compute. Its pixel rate is 107.7 GPixel/s and texture rate is 202.0 GTexel/s. The card supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4, which covers Rust's requirements.

In Rust, the GTX 1070's role is clear: it is the bottleneck in most scenarios. The 1080p Low result of 114 FPS shows the card can perform when the load is light, but the 4K Ultra result of 17.8 FPS reveals its limits. The GPU's 51st percentile ranking and average benchmark score of 12331 place it near the GeForce GTX 1650 SUPER (12504, 1.4% ahead), which is a notably newer and more efficient card. The GTX 1070's 8 GB VRAM is sufficient for Rust at 1080p and 1440p, but the 4K results suggest memory bandwidth, not capacity, is the limiting factor — the 256.3 GB/s bandwidth is simply insufficient for 4K texture loads in a game that streams large world data. The 150 W TDP and 450 W suggested PSU are reasonable for a modern system, but the card's end-of-life production status and 2016 release date are evident in its performance.

# FAQ

Q: What is the best resolution for this combo?

A: The data shows 1080p is the only resolution where the combo achieves playable frame rates across all settings. At 1440p, only Low settings exceed 60 FPS, and at 4K, even Low settings only reach 43.4 FPS.

Q: Why is the combo rank so low at 1450 out of 1717?

A: The CPU ranks in the 77th percentile, but the GPU ranks in the 51st. The low combo rank reflects that most tested combinations pair stronger GPUs with this CPU class, making the GTX 1070 the clear weak link.

Q: Does the CPU's performance scale well with more threads in Rust?

A: The 3DMark results show 16-thread score of 5873 versus 8-thread score of 4745, a 23.8% improvement. This suggests Rust benefits from more threads, but the 2-thread score of 1692 and 4-thread score of 3012 indicate that single-thread performance is still critical.

# Settings Recommendations

The measured data points to 1080p Medium as the best overall experience for this combo. At 78.8 FPS, it sits comfortably above the 60 FPS threshold while offering better visual fidelity than Low's 114 FPS. The jump from Low to Medium costs 35.2 FPS (30.9%), but the jump from High to Ultra costs only 12 FPS (19.5%), meaning Ultra's visual gains come at a disproportionately high performance price. For players prioritizing frame rate, 1080p Low at 114 FPS is the clear choice, especially in a game where quick reactions matter in PvP encounters.

At 1440p, the recommendation shifts to Low settings, which deliver 79.3 FPS. Medium at 52.7 FPS is playable but dips below 60 FPS, which many players find noticeable. High at 46.7 FPS and Ultra at 30.9 FPS are not recommended for smooth gameplay. At 4K, the data is unambiguous: only Low settings (43.4 FPS) approach playability, and even that is marginal. The 4K Medium (28.5 FPS), High (25 FPS), and Ultra (17.8 FPS) results are all below any reasonable playability threshold. Given the GPU's 8 GB VRAM and 256.3 GB/s bandwidth, 4K is not a viable option for this combo in Rust — users should stick to 1080p or accept 1440p Low. The data suggests that the GTX 1070's age (2016 release) and Pascal architecture are simply outmatched by Rust's current rendering demands at higher resolutions.
