The Best CPUs To Play Rust (2025)

Rust is one of the most successful survival video games out there currently and also happens to be one of the most regularly updated titles. It has made its way to more than just the PC, launching on both the Xbox and the PlayStation platforms. Despite consistent updates, it also happens to be one of the more demanding titles in terms of hardware, simply due to the sheer amount of assets in play for the game.

This is despite its relatively low hardware requirements on Steam compared to most of its peers. Much of this is possibly due to the increasingly complex and diverse build options that are in play for the game, which can cause clans to build larger bases to make it challenging for both their clients and the private servers they may play on.

Finding The Right Gaming CPU For Rust

Much like most of its survival multiplayer peers, Rust benefits directly from a more capable CPU as a CPU-bound title. This means users benefit from paying more attention to the CPU they invest in for their gaming than most of their other components, assuming a decent GPU is already in play.

The game particularly benefits from AMD's current and previous-generation X3D CPUs that offer a larger L3 cache, which the game uses relatively well compared to competing titles. However, it also benefits from higher CPU clocks and most users find that they hit a CPU bottleneck far easier than a GPU one, making choosing the right CPU for their Rust sessions a crucial decision.

Most users see their FPS cap at around 200 FPS even when using higher-end hardware with no frame rate limits. This could be considered acceptable by gamers in a title that leans heavily into multiplayer FPS themes that involve a variety of weapons.

The team at Game Rant has made a curated list of some of the best CPUs gamers can get to play a title like Rust with a focus on performance, upgrade potential, and value for money below.

The AMD Ryzen 7 7800X3D is an 8-core, 16-thread CPU that generally leads the charts when it comes to gaming performance. Much of this is due to its larger L3 cache which certain titles, including Rust, leverage exceptionally well. This, coupled with the IPC gains it offers over last-generation X3D CPUs such as the Ryzen 7 5800X3D (which is also a favorite among older Rust players) and the promise of AM5 as a newer platform with support for PCI-E 5.0, DDR5, and ongoing BIOS updates on newer chipsets make it a clear favorite.

The Ryzen 7 7800X3D is also considerably more power efficient than its peers from Intel as well as last-generation AMD CPUs. Given that Rust is a title users play for hours, if not days on end, this can help users rack up considerable power savings and work with a PC that has more thermal headroom for their GPU while exploring the world in Rust.

The Ryzen 7 7800X3D does trade at a significant premium currently for an octa-core CPU but does more than make up for that as a "specialized" gaming CPU that is considerably less demanding than the competition.

For users opting for an Intel-based setup for their Rust needs, the Intel Core i7 14700K delivers the goods. It offers solid single-core performance, high clocks, and extra cores for users wanting to switch back into productivity use cases or even stream their Rust escapades. The Intel Core i7 14700K is a 20-core, 28-thread juggernaut that comes with a free copy of Star Wars: Outlaws at the time of writing at certain retailers, making it a little cheaper than the Ryzen 7 7800X3D above when factoring in the cost of the game itself, even as it delivers excellent performance across the board in multiple titles, including Rust for gamers.

At the same time, Intel's CPUs run considerably hotter than the competition and the rebadged 14700K is no exception as it increases clocks versus its predecessor by another 200 MHz to keep things humming on the performance side of the equation. This results in a more demanding CPU in terms of both power and cooling, which makes for more expensive cooling needs, such as a high-end AIO to keep things going smoothly for the LGA 1700-based CPU.

Gamers searching for the fastest AM4 CPU to spruce up their gaming needs can stop their search at the Ryzen 7 5800X3D. Despite being the first X3D CPU in the business, it continues to defy the odds and remains a relevant force in modern gaming rigs. It does this while working with existing AM4 motherboards and DDR4 RAM, making it a slightly more cost-effective choice in the Ryzen 7 7800X3D for most games, including Rust currently.

At the same time, the AMD Ryzen 7 5800X3D is what users might call a dead-end upgrade due to most modern CPU upgrades (Zen 4 and Zen 5) appearing on the newer AM5 socket, making it a somewhat tough decision to invest north of $300 on a CPU that is not expected to have any upgrade paths in the foreseeable future.

Rust

You wake naked on a mysterious island armed only with a rock and a torch. You’ll need to brave natural dangers (from heat and cold to thirst and starvation), build a shelter, eat (or be eaten), scavenge materials. Explore the island, its abandoned settlements, mysterious monuments and the factions that occupy them. But, above all, watch out for other survivors...

Design and build bases to defend your territory or control the resources of the island. Research the tech tree, grow farms, command electricity, commandeer vehicles from horses to cars to boats to helicopters. Whatever it takes to get ahead.

There are no rules in Rust but the ones you make for yourself. Craft tools, armor and weapons to defend yourself. Cooperate with friends and allies and build a town together. Explore the island and what’s happening in it. Trade with other players. Or prey on them, raiding their bases and taking their hard-won goods.
