Design

Gracemont is the fourth generation out-of-order low-power Atom microarchitecture On i9-12900K, power for eight cores at 3.9GHz was measured at 48W, for AVX2 workloads. The Gracemont microarchitecture has the following enhancements over Tremont: * Level 1 cache per core: ** eight-way-associative 64 KB instruction cache ** eight-way-associative 32 KB data cache * New On-Demand Instruction Length Decoder * Instruction issue increased to five per clock (from four) * Instruction retire increased to eight per clock (from seven) * Execution ports (functional units) there are now 17 (from eight) * Reorder buffer increased to 256 entries (from 208) * Improved branch prediction * Support for AVX, AVX2,

FMA3 The FMA instruction set is an extension to the 128 and 256-bit Streaming SIMD Extensions instructions in the x86 microprocessor instruction set to perform fused multiply–add (FMA) operations."FMA3 and FMA4 are not instruction sets, they are indi ...
