The benchmarks were run via the rust-stdx/stdx library. A key reminder: xxHash functions are non-cryptographic checksums, not replacements for BLAKE3 or SHA-2. Raw benchmark data and CPU/memory bandwidth measurements are included. ## Full article daily.dev links to this article rather than hosting it.

XXH3-64 and XXH3-128 both reach approximately 130 GB/s on 1 MiB inputs when run in pure Rust with AVX-512 on an AMD EPYC 4245P (Zen 5). By comparison, XXH64 achieves ~24.7 GB/s and XXH32 ~12.4 GB/s on the same hardware. This throughput is sufficient to saturate the memory bandwidth of high-end server machines. _Rust developers pushing hashing performance to hardware limits track benchmarks like these on daily.dev._ ### Is XXH3 a cryptographic hash function? XXH3 is not a cryptographic hash function. It is a non-cryptographic checksum, designed as a faster alternative to CRC32 and CRC64. For cryptographic use cases, BLAKE3 or SHA-2 should be used instead. XXH3 is appropriate for data integrity checks, hash maps, and deduplication where collision resistance against adversaries is not required. _Developers choosing between hashing algorithms for their use case find comparisons like this on daily.dev._ ## Similar posts on daily.dev - [Rapidhash Unity port · Aras' website](https://daily.dev/posts/rapidhash-unity-port-aras-website-sgowqk7jm) · Aras Pranckevičius · 1 upvotes · 0 comments - [AVX-512 Optimization For Linux RAID Showing Up To 41% Improvement On AMD Ryzen 9 9950X](https://daily.dev/posts/avx-512-optimization-for-linux-raid-showing-up-to-41-improvement-on-amd-ryzen-9-9950x-poo478v4o) · Phoronix · 1 upvotes · 0 comments - [SIMD programming in pure Rust](https://daily.dev/posts/simd-programming-in-pure-rust-idnkdlsse) · Hacker News · 2 upvotes · 0 comments - [AVX-512 xor\_gen Continues To Look Exciting For Helping Linux RAID With Modern CPUs](https://daily.dev/posts/avx-512-xor-gen-continues-to-look-exciting-for-helping-linux-raid-with-modern-cpus-qv3oihkax) · Phoronix · 0 upvotes · 0 comments --- Tags: [#performance](https://daily.dev/tags/performance), [#rust](https://daily.dev/tags/rust) [View this post on daily.dev](https://daily.dev/posts/hashing-at-130-gb-s-with-xxh3-rust-and-avx-512-hi1qoazb1) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Hashing at 130 GB/s with XXH3, Rust and AVX-512","url":"https://daily.dev/posts/hashing-at-130-gb-s-with-xxh3-rust-and-avx-512-hi1qoazb1","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/hashing-at-130-gb-s-with-xxh3-rust-and-avx-512-hi1qoazb1"},"datePublished":"2026-08-11T08:53:58.082Z","dateModified":"2026-08-11T09:15:44.967Z","description":"Benchmark results show XXH3 (64-bit and 128-bit variants) achieving over 130 GB/s throughput on an AMD Zen 5 EPYC 4245P processor using pure Rust with AVX-512...","image":"https://media.daily.dev/image/upload/s--2-1xRawN--/f_auto/v1722860399/public/Placeholder%2011","thumbnailUrl":"https://media.daily.dev/image/upload/s--2-1xRawN--/f_auto/v1722860399/public/Placeholder%2011","isAccessibleForFree":true,"articleSection":"Sylvain Kerkour","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Sylvain Kerkour","logo":"https://media.daily.dev/image/upload/s--3ngWt4Yp--/f_auto,q_auto/v1786438308/logos/kerkour?_a=BAMAMicg0","url":"https://daily.dev/sources/kerkour"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/hashing-at-130-gb-s-with-xxh3-rust-and-avx-512-hi1qoazb1","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"performance,rust","timeRequired":"PT4M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sylvain Kerkour","item":"https://daily.dev/sources/kerkour"},{"@type":"ListItem","position":3,"name":"Hashing at 130 GB/s with XXH3, Rust and AVX-512"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/hashing-at-130-gb-s-with-xxh3-rust-and-avx-512-hi1qoazb1#faq","mainEntity":[{"@type":"Question","name":"How fast is XXH3 in Rust with AVX-512 on AMD Zen 5?","acceptedAnswer":{"@type":"Answer","text":"XXH3-64 and XXH3-128 both reach approximately 130 GB/s on 1 MiB inputs when run in pure Rust with AVX-512 on an AMD EPYC 4245P (Zen 5).
