The AMD 4700S and 4800S desktop processors are part of a "desktop kit" that comes bundled with a motherboard and GDDR6 RAM. The CPU is soldered, and provides 4 PCIe 2.0 lanes. These are reportedly cut-down variants of the APUs found on the PlayStation 5 and Xbox Series X and S repurposed from defective chip stock.
The instructions were mainly promoted by AMD, but were supported on some non-AMD CPUs as well. The processors supporting 3DNow! were: AMD K6-2, K6-III, and all processors based on the K7, K8 and K10 microarchitectures. (Later AMD microarchitectures such as Bulldozer, Bobcat and Zen do not support 3DNow!) IDT WinChip 2 and 3
Zen 2 is a computer processor microarchitecture by AMD.It is the successor of AMD's Zen and Zen+ microarchitectures, and is fabricated on the 7 nm MOSFET node from TSMC.The microarchitecture powers the third generation of Ryzen processors, known as Ryzen 3000 for the mainstream desktop chips (codename "Matisse"), Ryzen 4000U/H (codename "Renoir") and Ryzen 5000U (codename "Lucienne") for ...
The instructions are usually part of an executable program, often stored as a computer file and executed on the processor. The x86 instruction set has been extended several times, introducing wider registers and datatypes as well as new functionality.
The K6 was generally pin-compatible with the Intel Pentium (unlike NexGen's existing processors). AMD K6-2 – an improved K6 with the addition of the 3DNow! SIMD instructions. AMD K6-III Sharptooth – a further improved K6 with three levels of cache – 64 KB L1, 256 KB full-speed on-die L2, and a variable (up to 2 MB) L3.
AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly. [2]
The XOP (eXtended Operations [1]) instruction set, announced by AMD on May 1, 2009, is an extension to the 128-bit SSE core instructions in the x86 and AMD64 instruction set for the Bulldozer processor core, which was released on October 12, 2011. [2] However AMD removed support for XOP from Zen (microarchitecture) onward. [3]
Llano AMD Fusion (K10 cores + Redwood-class GPU) (launch Q2 2011, this is the first AMD APU) uses Socket FM1 Bulldozer architecture; Bulldozer, Piledriver, Steamroller, Excavator (2011–2017) [ edit ]
