Agner's CPU blog

Hi Dr. Fog,

Are you expecting to test more recent AMD processors soon? (Zen 2/3 or maybe even 4)

Reason I'm asking is because my project relies on bit manipulation instructions (BMI2), and while AMD Ryzen 1 implements the instruction set, they're super slow.

Thanks for everything!
Vlad

I will be happy to test it if somebody gives me access to it. I can test it through a remote login to a Linux machine.

I can provide remote access to a Linux machine with Ryzen 3700X. Send me PM.

Hi Agner, I also have the Ryzen 3900X I could give you remote access to if you would like to test it as well.

Thanks for the offer, TomasCito. I am finished testing the Ryzen 3000 so I will probably not need to test another.

If anybody has access to the new Chinese Zhaoxin processor, I would very much like to test it.
