Amd ryzen threadripper12/2/2023 ![]() Mem: Quad-channel, up to 1 TiB, up to 512 GiB per channel (2 TiB in total).2900-Series doubled the core count to as much as 32 cores and introduced a new automatic overclocking feature called Precision Boost Overdrive. The biggest change second-generation brought is introduction of higher core count models but at the cost of a much higher thermal design point. 2nd-gen parts still use the same sTR4 socket and are fully backwards-compatible with 1st-generation. Tech: AMD-V/ Vi, Precision Boost, SMEP, 2-way SMT, XFR (+200 MHz)Ģ900-Series (Zen+) See also: Zen+ µarch and Codename ColfaxĪnnounced in early August 2018, second-generation Threadripper processors are based on the Zen+ microarchitecture ,fabricated on GlobalFoundries 12 nm process, and feature a modest frequency and memory improvement.ISA: Everything up to AVX2 (i.e., SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2), and SHA.I/O: 60 PCIe 3.0 lanes (x48 lanes for multiple GPUs, x12 for I/O).Memory controller: Quad-channel, up to 512 GiB per channel (2 TiB in total).Models 1900-Series (Zen) See also: Zen µarch and Codename WhitehavenĪnnounced in May 2017 and introduced in July of 2017, first-generation Threadripper is based on the Zen microarchitecture and is manufactured on GF's 14 nm process. Higher-performance dies allow for higher efficiency in terms of power consumption at higher clock speeds and in theory allow for higher overclocking overhead. ![]() The top 5% Ryzen dies are then used for the Threadripper models. Since every die has a slightly different performance characteristics, even from within the same wafer, AMD sorts those dies based on this performance. While Threadripper uses the same dies as the ones used for Ryzen, their performance characteristics are a little different.
