As of 2019, all Zen-based AMD processors support AMD-V. The CPU flag for AMD-V is "svm". This may be checked in BSD derivatives via dmesg or sysctl and in Linux via /proc/cpuinfo. [19] Instructions in AMD-V include VMRUN, VMLOAD, VMSAVE, CLGI, VMMCALL, INVLPGA, SKINIT, and STGI. With some motherboards, users must enable AMD SVM feature in the ...
Mode Based Execution Control (MBEC) is an extension to x86 SLAT implementations first available in Intel Kaby Lake and AMD Zen+ CPUs (known on the latter as Guest Mode Execute Trap or GMET). [10] The extension extends the execute bit in the extended page table (guest page table) into 2 bits - one for user execute, and one for supervisor execute.
The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2]
An x86-64 processor acts identically to an IA-32 processor when running in real mode or protected mode, which are supported modes when the processor is not in long mode.. A bit in the CPUID extended attributes field informs programs in real or protected modes if the processor can go to long mode, which allows a program to detect an x86-64 processor.
In April 2005, AMD introduced a subset of SSE3 in revision E (Venice and San Diego) of their Athlon 64 CPUs. [2] The earlier SIMD instruction sets on the x86 platform, from oldest to newest, are MMX, 3DNow! (developed by AMD, no longer supported on newer CPUs), SSE, and SSE2. SSE3 contains 13 new instructions over SSE2. [3]
In computing, Streaming SIMD Extensions (SSE) is a single instruction, multiple data instruction set extension to the x86 architecture, designed by Intel and introduced in 1999 in its Pentium III series of central processing units (CPUs) shortly after the appearance of Advanced Micro Devices (AMD's) 3DNow!.

AMD claimed SSE5 would provide dramatic performance improvements, particularly in high-performance computing (HPC), multimedia, and computer security applications, including a 5x performance gain for AES encryption and a 30% performance gain for the discrete cosine transform (DCT) used for example in video processing.
