Technical Specifications
Platform & Compute
The 9975WX has 32 cores and 64 threads, 128 MB L3 and a 4 GHz base clock. AMD’s exact page prints 4 GHz while its model table prints 4.0 GHz; those values are identical without rounding. The published 5.4 GHz maximum boost is a separate single-core limit. An sTR5 socket does not establish OEM motherboard or BIOS compatibility. AMD lists WRX90, TRX50 and Pro 695 supporting chipsets, but Pro 695 memory, population and I/O limits are Unknown. Confirm the exact OEM CPU support list, BIOS, DIMMs, cooling and power design. The cited documents discuss single-socket workstations; two-socket support is Unknown.

Performance & Capacity
Maximum boost is up to 5.4 GHz for a single core running a bursty single-threaded workload. Thermal paste, cooling, motherboard design and BIOS, chipset drivers and OS updates affect the result (GD-150). It is not a sustained or all-core boost guarantee. Base clock represents the average effective base frequency of all cores; all-core boost is Unknown.

Memory
The processor lists DDR5 RDIMM, eight supported memory channels, ECC enabled by default and up to 6400 MT/s. These are transfer-rate specifications, not controller clock MHz. Actual rate and capacity depend on the selected platform, DIMM type and population, motherboard and BIOS qualification. DPC limits, a DIMM population speed table and absolute memory bandwidth in GB/s are Unknown; no computed bandwidth is presented as a published AMD specification.

Platform Resource Limits
WRX90 platform-level limits are eight memory channels, up to 2 TB DDR5 RDIMM and up to 6400 MT/s, with 148 total / 144 usable / 128 Gen5 native PCIe lanes. These are platform ceilings, not validation of a particular motherboard, DIMM kit or slot layout. TRX50 platform-level limits are four memory channels, up to 1 TB DDR5 RDIMM and up to 6400 MT/s, with 92 total / 88 usable / up to 80 Gen5 native PCIe lanes. Do not apply WRX90 resources or feature parity to every TRX50 system.

FAQ
Which ordering identities identify Ryzen Threadripper PRO 9975WX?
AMD lists tray OPN 100-000000723 and boxed OPN 100-100000723WOF for the same Ryzen Threadripper PRO 9975WX. These are packaging ordering identities, not separate processor models or additional product pages. Package contents and present supply require confirmation.
What distinguishes Ryzen Threadripper PRO 9975WX for workstation selection?
The 9975WX has 32 cores and 64 threads, 128 MB L3 and a 4 GHz base clock. AMD’s exact page prints 4 GHz while its model table prints 4.0 GHz; those values are identical without rounding. The published 5.4 GHz maximum boost is a separate single-core limit.
Do WRX90 and TRX50 expose the same resources?
WRX90 platform-level limits are eight memory channels, up to 2 TB DDR5 RDIMM and up to 6400 MT/s, with 148 total / 144 usable / 128 Gen5 native PCIe lanes.

TRX50 platform-level limits are four memory channels, up to 1 TB DDR5 RDIMM and up to 6400 MT/s, with 92 total / 88 usable / up to 80 Gen5 native PCIe lanes. Do not apply WRX90 resources or feature parity to every TRX50 system. An sTR5 socket does not establish OEM motherboard or BIOS compatibility. AMD lists WRX90, TRX50 and Pro 695 supporting chipsets, but Pro 695 memory, population and I/O limits are Unknown. Confirm the exact OEM CPU support list, BIOS, DIMMs, cooling and power design. The cited documents discuss single-socket workstations; two-socket support is Unknown.
What conditions apply to the memory and clock specifications?
The processor lists DDR5 RDIMM, eight supported memory channels, ECC enabled by default and up to 6400 MT/s. These are transfer-rate specifications, not controller clock MHz. Actual rate and capacity depend on the selected platform, DIMM type and population, motherboard and BIOS qualification. DPC limits, a DIMM population speed table and absolute memory bandwidth in GB/s are Unknown; no computed bandwidth is presented as a published AMD specification. Maximum boost is up to 5.4 GHz for a single core running a bursty single-threaded workload. Thermal paste, cooling, motherboard design and BIOS, chipset drivers and OS updates affect the result (GD-150). It is not a sustained or all-core boost guarantee. Base clock represents the average effective base frequency of all cores; all-core boost is Unknown.
Does the listed socket qualify any motherboard or cooler?
An sTR5 socket does not establish OEM motherboard or BIOS compatibility. AMD lists WRX90, TRX50 and Pro 695 supporting chipsets, but Pro 695 memory, population and I/O limits are Unknown. Confirm the exact OEM CPU support list, BIOS, DIMMs, cooling and power design. The cited documents discuss single-socket workstations; two-socket support is Unknown. Default TDP is 350 W. A configurable TDP interval is Unknown. AMD lists the PIB thermal solution as Not Included and a 95°C maximum operating temperature; neither establishes the suitability of a particular cooler. Exact OEM thermal qualification and complete package contents remain Unknown.
Does the published launch date establish present availability?
AMD’s exact-model Launch Date field is 07/23/25 (2025-07-23). Current lifecycle is Unknown. Current manufacturing, end-of-life, end-of-sale and commercial availability are Unknown.
