Socket AM4 is a PGA microprocessor socket used by AMD's central processing units (CPUs) built on the Zen (including Zen+, Zen 2 and Zen 3) and Excavator microarchitectures. [1] [2] AM4 was launched in September 2016 and was designed to replace the sockets AM3+, FM2+ and FS1b as a single platform.
The Ryzen family is an x86-64 microprocessor family from AMD, based on the Zen microarchitecture.The Ryzen lineup includes Ryzen 3, Ryzen 5, Ryzen 7, Ryzen 9, and Ryzen Threadripper with up to 96 cores.
First generation was built with a separate L2-cache chip on a board inserted into a slot and introduced extended MMX. The second generation returned to the traditional socket form factor with fully integrated L2-cache running at full speed. The third generation, branded as XP, introduced full support for SSE.
Athlon was the first x86 processor with a 128 KB [26] split level-1 cache; a 2-way associative cache separated into 2×64 KB for data and instructions (a concept from Harvard architecture). [27] SRAM cache designs at the time were incapable of keeping up with the Athlon's clock scalability, resulting in compromised CPU performance in some ...
In December 2019, AMD started producing first generation Ryzen products built using the second generation Zen+ architecture. [41] An example is the Ryzen 5 1600, with new batches having an "AF" identifier instead of its usual "AE", essentially being an underbinned Ryzen 5 2600 with the same specifications as the original Ryzen 5 1600.
The mainstream product (A8-7680) has 4 Excavator cores and a GPU based on GCN1.2 architecture. Also, an entry-level APU (A6-7480) with 2 Excavator cores is also launched. Budget and mainstream markets (desktop and mobile): Bristol Ridge, and Stoney Ridge (for entry level notebooks), APUs [29] Bristol Ridge APUs utilize socket AM4 and DDR4 RAM
But we began looking at things differently with a lot of innovation and determination and we achieved major improvements." He added that the performance of the seventh generation chips was improved by 12% for applications and 19% for Internet use compared with the sixth generation chips. [19]
GPU (based on VLIW4 architecture) instruction support: DirectX 11, Opengl 4.2, DirectCompute, Pixel Shader 5.0, Blu-ray 3D, OpenCL 1.2, AMD Stream, UVD3; Integrated PCIe 2.0 controller, and Turbo Core technology for faster CPU/GPU operation when the thermal specification permits
