Castle Peak (CPK/CPKWS) is the codename for AMD's highest-performance enthusiasts microprocessors serving as a successor to Colfax, released in late 2019. Castle Peak-based processors are based on the Zen 2 microarchitecture and are fabricated on a TSMC 7 nm process.

Castle Peak-based microprocessors are branded as 3rd-generation Ryzen Threadripper.

Overview[edit]

Castle Peak chips are a series of high-performance desktop processors designed by AMD based on their Zen 2 microarchitecture.

Input/Output Interfaces[edit]

"Castle Peak" processors integrate eight PCIe controllers and four SATA controllers. Workstation (-WX) models have eight 16-lane PCIe Gen 1, 2, 3, 4 (16 GT/s) interfaces, each configurable as up to eight x16/x8/x4/x2/x1 wide (e.g. 1x4 + 4x1 + 1x8) links, so 128 lanes total. Some of these lanes are configurable as SATA Gen 1, 2, 3 (6 Gb/s) link. Up to 32 SATA ports are available from the processor in total, as well as four USB 3.2 Gen 2×1 (10 Gb/s) ports, and various low speed interfaces. For details see Socket sWRX8.

On "Castle Peak" HEDT processors only one half of these PCIe and SATA resources are available, i.e. 64 PCIe lanes on four 16-lane interfaces and up to 16 SATA ports in total. For details see Socket sTRX4.

On Socket sTRX4 and sWRX8 motherboards the PCIe interfaces are generally used for x8 and x16 (electrically) PCIe slots and x4 M.2 NVMe/SATA SSD connectors, leveraging few of the CPU's SATA ports. One x8 PCIe link on the processor is reserved to attach the AMD TRX40 (HEDT) or WRX80 (workstation) chipset which serves as I/O expander. These devices are members of the AMD-500 Series along with the X570 chipset for Socket AM4 processors. A notable difference are four additional PCIe lanes available on the X570 as that chipset is attached with an x4 link.

Both the TRX40 and WRX80 offer 16 lanes (plus 8-lane CPU link) PCIe Gen 1, 2, 3, 4; 12 SATA Gen 1, 2, 3 ports, eight sharing pins with the PCIe interface and four dedicated; eight USB 3.2 Gen 2 (10 Gb/s) ports, and four (TRX40) or five (WRX80) USB 2.0 ports. The chipset PCIe interfaces are generally used for PCIe slots, on-board Ethernet controllers, M.2 NVMe/SATA SSD and M.2 WLAN connectors. An audio interface is not provided by the processor or the chipsets, an audio controller is commonly attached as on-board USB device. The sTRX4/TRX40 platform supports overclocking, the sWRX8/WRX80 platform does not.

Common Features[edit]

All Castle Peak processors have the following:

Up to 64 cores / 128 threads
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

HEDT processors:

64 PCIe lanes
Quad-channel Memory
Up to DDR4-3200 ECC
Up to 256 GiB using eight 32 GiB UDIMMs (up to 1 TiB/channel addressable)

Workstation processors:

128 PCIe lanes
Octa-channel Memory
Up to DDR4-3200 ECC
Up to 2 TiB using eight 256 GiB LRDIMMs or 3DS DIMMs (up to 1 TiB/channel addressable)
