The RX 570 is a budget-tier GPU best suited to 1080p gaming at medium settings. Its performance ceiling means the CPU rarely becomes the bottleneck in this pairing, which shifts the focus toward value - choosing a processor that matches the GPU’s tier without spending more than necessary. The five picks below cover the best CPU options for RX 570 builds at various price levels.
| CPU | Cores/Threads | Best For | Approx. Price |
|---|---|---|---|
| Ryzen 5 3600 | 6C/12T | Best overall pairing | ~$70-$85 |
| Intel Core i5-9400F | 6C/6T | Best legacy Intel pick | ~$50-$70 |
| Ryzen 3 3300X | 4C/8T | Best 4-core AMD option | ~$60-$80 |
| Intel Core i3-10100 | 4C/8T | Best budget Intel pick | ~$40-$60 |
| Ryzen 5 1600 AF | 6C/12T | Lowest cost 6-core option | ~$40-$60 |
Ryzen 5 3600 - Best CPU to Pair with the RX 570
The Ryzen 5 3600 is technically overqualified for the RX 570, which is exactly why it works so well. By ensuring the processor is never the bottleneck, the RX 570 reaches its full performance in every game without exception. The 3600 provides future value if the GPU is upgraded later, meaning the CPU investment remains useful well beyond this card’s lifespan. Six Zen 2 cores, strong single-thread performance, and a wide AM4 motherboard ecosystem make it the ideal pairing for anyone who wants zero compromise in a budget build.

Intel Core i5-9400F - Best Legacy Intel for RX 570
The Core i5-9400F delivers six cores without Hyper-Threading and a 4.1 GHz boost clock that handles the RX 570’s requirements with ease. The F variant lacks integrated graphics, which is irrelevant in a discrete GPU build. On an LGA 1151 B365 or H310 motherboard, platform costs are minimal. For builders sourcing parts from the secondhand market to build the most affordable complete PC possible, the i5-9400F on an LGA 1151 board is one of the most cost-effective foundations available. Gaming performance with the RX 570 is smooth at 1080p medium settings.

Ryzen 3 3300X - Best 4-Core AMD CPU for RX 570
The Ryzen 3 3300X is a 4-core, 8-thread Zen 2 processor with a unique dual-CCX design that gives it lower latency and better gaming performance than many 6-core competitors from the same era. Its single-thread performance is strong enough to ensure the RX 570 is GPU-limited at 1080p in nearly all scenarios, and the low price makes it a practical fit for tight-budget builds. AM4 compatibility and reasonable thermal output on its included cooler make it easy to deploy in small or mid-tower cases without additional cooling investment.

Intel Core i3-10100 - Best Budget Intel for RX 570
The Core i3-10100 matches the Ryzen 3 3300X closely in gaming workloads and is available at very low secondhand prices on LGA 1200 boards. Four cores with Hyper-Threading and a 4.3 GHz boost clock handle 1080p gaming titles without issue alongside the RX 570. For a complete system built entirely from secondhand parts to minimize cost, the i3-10100 on an affordable LGA 1200 board is one of the cheapest functional gaming CPU configurations available. Board availability is good and platform costs are low.

Ryzen 5 1600 AF - Lowest Cost 6-Core CPU for RX 570
The Ryzen 5 1600 AF is a revised version of the Ryzen 5 1600 built on the 12nm Zen+ die, delivering near-3600-level gaming performance at a fraction of the cost. Six cores and twelve threads at 3.2 GHz base with 3.6 GHz boost pair adequately with the RX 570 for 1080p gaming. It is the lowest-cost 6-core option for an AM4 system and pairs with budget B450 or A320 boards to create a full gaming platform at minimal expense. For absolute minimum budget builds, this is the most core-rich option available.

What to Look For
For an RX 570 build, the GPU is almost always the performance limit, so the CPU primarily needs to stay out of the way rather than lead the system. A 4-core processor from the last 5 years or any 6-core option is sufficient. Prioritize platform cost: AM4 boards are cheap and available for Ryzen options; LGA 1151 and LGA 1200 boards are similarly affordable for Intel. Ensure dual-channel memory is used regardless of speed, as single-channel memory can reduce RX 570 performance on AMD platforms due to shared memory bandwidth.
Final Thoughts
The Ryzen 5 3600 is the top pick for pairing with the RX 570, offering performance that grows with the system if the GPU is upgraded. For the tightest budgets, the Ryzen 5 1600 AF provides six cores at a rock-bottom price, and the Intel Core i3-10100 is the Intel equivalent at similarly low cost. The Ryzen 3 3300X is the best single-CPU recommendation if you are limited to 4 cores but want the best possible performance within that constraint.
Frequently asked questions
What CPU pairs well with the RX 570 for 1080p gaming?+
A 4-core to 6-core CPU with a boost clock above 3.5 GHz pairs well with the RX 570 for 1080p gaming at medium-to-high settings. The Ryzen 5 3600, Intel Core i5-9400F, and Ryzen 5 1600 AF are all solid matches. The RX 570 is an entry-level GPU where the processor rarely becomes the bottleneck at 1080p standard frame rates, so mid-range CPU selection is more than sufficient to fully utilize this card.
Will a 4-core CPU bottleneck the RX 570?+
A modern 4-core CPU like the Ryzen 3 3100 or Intel Core i3-10100 will not bottleneck the RX 570 in standard 1080p gaming scenarios. The RX 570 is a GPU that reaches its performance ceiling relatively quickly, meaning the processor rarely becomes the limiting factor. Only very old 4-core chips from Intel 6th gen or older or AMD FX-4000 series may show mild bottlenecking in a few CPU-intensive titles. Anything from the last 4-5 years with 4 cores will pair fine.
Is the RX 570 still usable for gaming in 2026?+
The RX 570 handles 1080p gaming at medium settings in older titles and low-to-medium settings in newer demanding games in 2026. For esports titles and less demanding games, it remains capable at medium-to-high settings and 60 fps targets. It is no longer competitive for high refresh rate gaming or 1440p, but as a budget or secondary system GPU it continues to serve basic gaming needs. Used pricing is low, making it a low-risk option for budget builds.
