If you need speed and security, do not use either. Reach for BLAKE3 . It is nearly as fast as xxHash (within 2-3x) but offers cryptographic security. However, if you must choose between MD5 and xxHash for a non-security task, xxHash is faster and has better collision resistance for accidental collisions than MD5's broken cryptographic guarantees.

If you don't need to worry about hackers intentionally "spoofing" your data, It provides the same reliability as MD5 at a fraction of the hardware cost. However, if you are handling passwords or sensitive security tokens, you should skip both and use a modern, secure algorithm like Argon2 or SHA-3 . If you'd like, I can help you implement one of these by:

For security, neither is acceptable. Modern standard: SHA-256 or BLAKE3.
