c - Do Intel and AMD processor have the same assembler
Processor Specifications | AMD Windows 10 - 64-Bit Edition, RHEL x86 64-Bit, Ubuntu x86 64-Bit *Operating System (OS) support will vary by manufacturer. 3200MHz: DDR4: 2: 2100 MHz: Radeon™ Graphics: 8: Yes: Yes: AMD Ryzen™ 3 3100: AMD Ryzen™ Processors: AMD Ryzen™ 3 Desktop Processors: Boxed Processor: 05/2020: 4: 8: 3.6GHz: Up to 3.9GHz: 256KB: 2MB: 16MB: Yes: TSMC 7nm FinFET: AM4: PCIe 4.0: Wraith Stealth: 65W 64 bit - what is the difference between x86_64 amd64 and AMD64 is the real 64 bits architecture that AMD created and intel licensed it and uses it even today (just as AMD had the license to use x86 on the 32 bit CPUs). x86_64 far as i know is nothing more than a 32 bit CPU that can address the extra memory that a supposed 64 bit system need (so like a 32 bit system that recognizes and uses more than 4GB of RAM).
