How many H/s does a Ryzen 7 5800X get on RandomX?

A Ryzen 7 5800X typically gets about 8,000–11,000 H/s on RandomX with a dedicated mining program and a reasonably configured PC. A well-tuned setup can reach roughly 11,000–12,000 H/s, but you should not expect those desktop-miner speeds from browser mining.

What that speed means

H/s means hashes per second: the number of mining calculations your processor completes each second. You may also see the result written as 8–11 kH/s, where one kH/s equals 1,000 H/s.

RandomX is Monero’s mining algorithm—the set of calculations miners perform to help secure the network. It favors processors such as your Ryzen rather than graphics cards.

For a 5800X, these are useful rough expectations, not guaranteed results:

• Around 8,000 H/s: a plausible result with ordinary settings or some performance limits.
• Around 9,000–11,000 H/s: a reasonable target for a properly configured dedicated miner.
• Around 11,000–12,000 H/s: possible with favorable memory settings and careful tuning.

A result well below that range does not automatically mean your processor is faulty.

Why the 5800X suits RandomX

Your 5800X has 8 physical cores and 16 processing threads. Threads let the processor work on multiple streams of instructions at once.

It also has 32 MB of L3 cache, a small, very fast store of data inside the processor. RandomX needs about 2 MB of L3 cache per mining thread, so that capacity fits 16 mining threads well.

That makes 16 threads a sensible starting point for dedicated mining. Still, test fewer threads if you also use the PC for work or want less heat and noise.

RandomX’s fast mode also needs a dataset of about 2,080 MB in system memory, plus other working memory. Having enough RAM matters, but buying much more RAM than you need will not, by itself, increase your mining speed.

What changes your actual result

Two PCs with the same 5800X can produce noticeably different results. Important factors include:

• Memory configuration: Two memory channels and good memory timings help. Timings describe how quickly RAM responds.
• Huge pages: These are larger blocks of memory that a dedicated miner can use to reduce memory-management overhead.
• Cooling: A hot processor may lower its speed to protect itself.
• Power settings: Lower power limits can reduce speed while improving energy efficiency.
• Other programs: Games, background tasks, and other workloads compete for processor time.

For a useful comparison, let your miner settle, then check its average speed over several minutes rather than its highest brief reading. Measure whole-PC electricity use if you want to judge running costs; the processor’s advertised power rating is not your wall-socket consumption.

If you are mining in your browser

Treat the 8,000–11,000 H/s range as a dedicated-miner reference, not a browser promise. Browser software has different memory, execution, and background-tab restrictions. Your result depends heavily on how the site implements mining.

Also check that the displayed speed actually measures RandomX. A rate for another algorithm is not directly comparable.

The bottom line

For your Ryzen 7 5800X, roughly 9,000–11,000 H/s is a sensible dedicated RandomX mining target. Benchmark your own setup, and judge browser mining by its measured results rather than desktop-miner figures.
