AMD Ryzen: Threadripper is dead, long live Threadripper Pro

High-end motherboards with the TRX40 chipset no longer have a future after just one generation of Ryzen Threadripper processors: from now on AMD will focus the Threadripper class on workstations and will only carry Pro models for better equipped WRX80 motherboards. AMD wants to conquer the high-end desktop PC (HEDT) niche with this platform in the future. Three Ryzen Threadripper Pro CPUs will also be available later this year: the 64-core 5995WX, 32-core 5975WX, and 24-core 5965WX.

However, AMD cannot be fixed on the time window. In a blog post, the company writes, “We assume these processors will also be available to our DIY community later this year.” AMD is already lagging behind as the 5000WX processors still use the Zen 3 architecture, while the Zen 4 core Ryzen 7000 will appear for regular desktop PCs this fall.

WRX80 motherboards connect eight memory channels of Ryzen Threadripper Pro CPUs, which results in 16 slots for up to 2TB of DDR4-3200 RAM on expensive boards, and can also handle both ECC-compatible UDIMMs and RDIMMs. 128 PCI Express 4.0 lanes are available for graphics cards, PCIe SSDs, and other expansion cards. Previous TRX40 motherboards are limited to four memory channels and 64 PCIe 4.0 lanes.

AMD is making a concession to the HEDT staff: in the future, manufacturers will sell WRX80 motherboards with a focus on consumers, where the CPU and memory can be overclocked. However, this will not be possible with all motherboards.

Anyone who already uses a Ryzen Threadripper Pro 3000WX with a previous WRX80 motherboard can upgrade to a 5000WX model if the manufacturer provides a BIOS update. Everyone else gets nothing: TRX40 motherboards are limited to Ryzen Threadripper 3000X, for previous X399 cards there were only 1000 and 2000 models.

Meanwhile, the end of life is already coming for the WRX80 platform, as the next generation Ryzen Threadripper Pro 7000WX with Zen 4 architecture, PCIe 5.0 and DDR5 is also expected to require new motherboards.

From July 2022, new ready-made workstations will be released with Ryzen Threadripper Pro 5000WX, after Lenovo has had them exclusively in recent months. Dell has opportunely announced the Precision 7865 Tower.
