Ryzen Threadripper (pronounced Rye-Zen Thread-ripper) is a family of 64-bit x86 enthusiasts/high-performance desktop microprocessors. Ryzen Threadripper is geared toward prosumers that rely on heavily threaded applications and multitasking.

Overview

Ryzen Threadripper is a family of high core count x86 microprocessors. Threadripper is geared toward mainstream users who rely on heavily threaded applications and multitasking beyond what the Ryzen 7 processors can provide.

Top 5% of dies become Threadripper.

While Threadripper uses the same dies as the ones used for Ryzen, their performance characteristics are a little different. Since every die has a slightly different performance characteristics, even from within the same wafer, AMD sorts those dies based on this performance. The top 5% Ryzen dies are then used for the Threadripper models. Higher-performance dies allow for higher efficiency in terms of power consumption at higher clock speeds and in theory allow for higher overclocking overhead.

2900-Series (Zen+)

See also: Zen+ µarch and Codename Colfax

Announced 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. 2nd-gen parts still use the same sTR4 socket and are fully backwards-compatible with 1st-generation. The biggest change second-generation brought is introduction of higher core count models but at the cost of a much higher thermal design point. 2900-Series doubled the core count to as much as 32 cores and introduced a new automatic overclocking feature called Precision Boost Overdrive.

All models have

• Mem: Quad-channel, up to 1 TiB, up to 512 GiB per channel (2 TiB in total)
• I/O: 60 PCIe 3.0 lanes (x48 lanes for multiple GPUs, x12 for I/O)
• TDP: 180 W / 250 W
• 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
• Tech: AMD-V/Vi, Precision Boost 2, SMEP, 2-way SMT, XFR 2, and Precision Boost Overdrive
• L3$: 32 / 64 MiB

Announced in November 2019, tird-generation Threadripper processors are based on the Zen 2 microarchitecture ,fabricated on TSMC 7 nm process, bringing a 15% IPC improvement along with a modest frequency improvement. 3rd-gen microprocessors do not maintain backwards compatability and use a new sTRX4 socket, supporting much higher TDPs and I/O, including new support for PCIe Gen 4. Third-generation Threadripper currently feature the same core count as 2nd-gen but are expected to increase to 64 cores in the future.

All models have

• Mem: Quad-channel, up to ? TiB
• I/O: 64 PCIe 4.0 lanes
• TDP: 280 W
