AMD reported that the branch prediction unit has been reworked. In order to feed the backend, which has been widened to support 256-bit operation, the front-end throughput was improved. Most of the fine details have not been revealed by AMD yet. 4-Kbyte and 2-Mbyte pages, PDEs to speed up table walks.2,048 entry L2 TLB, 16-way set associative.512 entry L2 TLB, 8-way set associative.64 entry L1 TLB, fully associative, all page sizes.Up to PC4-25600L (DDR4-3200 RDIMM/LRDIMM), ECC supported.8 channels per socket, up to 16 DIMMs, max.Renoir: 4 MiB/CCX, shared across all cores.Matisse, Castle Peak, Rome: 16 MiB/CCX, shared across all cores.WBNOINVD - Write back and do not flush internal caches, initiate same of external cachesįurthermore, the User-Mode Instruction Prevention ( UMIP) extension.īlock Diagram Individual Core.CLWB - Write back modified cache line and may retain line in cache hierarchy.Zen 2 introduced a number of new x86 instructions: This list is incomplete you can help by expanding it. Decoupling of MemClk from FClk, allowing 2:1 ratio in addition to 1:1.2.3x transfer rate per link (25 GT/s, up from ~10.6 GT/s).Increased 元 latency (~40 cycles, up from ~35 cycles).2x 元 cache slice (16 MiB, up from 8 MiB).0.5x L1 instruction cache (32 KiB, down from 64 KiB).Larger Reorder Buffer (224, up from 192).Larger scheduler (4x16 ALU + 1x28 AGU, up from 4x14 ALU + 2x14 AGU.Increased number of registers (180, up from 168).2x wider LSU (2x256-bit L/S, up from 128-bit).2x wider EUs (256-bit FMAs, up from 128-bit FMAs).2x wider datapath (256-bit, up from 128-bit).Larger µOP cache (4096 entries, up from 2048).Higher IPC (AMD self-reported up to 15% IPC). Zen 2 inherits most of the design from Zen+ but improves the instruction stream bandwidth and floating-point throughput performance. Note: Initial support in GCC 9 and LLVM 9.The server I/O Die (sIOD) is fabricated on GlobalFoundries 14 nm process.The client I/O Die (cIOD) is fabricated on GlobalFoundries 12 nm process.The Core Complex Die (CCD) is fabricated on TSMC 7 nm HPC process.Zen 2 comprises multiple different components: 2 ECC support is unavailable on AMD APUs.
