Backside line: With third era Threadripper processors set to reach later this month, AMD has vowed to supply long-term assist for the brand new sTRX4 socket. This can be a good factor as a result of the high-bandwidth sockets are usually not cross-compatible with earlier era sTR4 motherboards that had been used for the first- and second-generation Threadrippers.
Third-generation Ryzen Threadripper CPUs had been introduced final week. On Friday, AMD posted a video highlight on the HEDT Treadripper 3960X and 3970X (watch under), each primarily based on AMD’s 7nm Zen 2 structure.
Threadripper 3960X may have 24 cores/48 threads, whereas Threadripper 3970X packs in 32 cores with 64 threads. The brand new CPUs depend on a brand new sTRX4 platform, which implies they’ll solely work on new TRX40 motherboards. In contrast to Ryzen AM4, Threadripper is just not backwards suitable with the sTR4 socket used within the first and second-generation Threadripper.
Despite the fact that the sTRX4 socket has the identical variety of pins (4096) as sTR4, they’re electronically incompatible. In accordance with AMD, the pin mapping to voltage or knowledge is fully totally different. Due to this fact, you gained’t be capable to plug a third-gen Threadripper into your current X399 motherboard, however this isn’t with out what AMD considers good cause.
“AMD’s sTRX4 socket is not being changed anytime quickly.”
“There are two important causes for this,” AMD stated within the r/AMD subreddit. “[First,] we needed to drive most efficiency for the third Gen AMD Ryzen Threadripper processors, and sTRX4 helps us do precisely that. [Second,] the socket change additionally units us up properly for future growth and scalability of the Threadripper platform,
The corporate explains that third-generation Threadripper processors may have a complete of 88 PCIe Gen four lanes with 72 usable (CPU motherboard).
“The online of complete versus usable is as a result of we’re additionally rising the CPU<->chipset hyperlink from 4x Gen4 to 8x Gen4—quadruple the bandwidth vs. 2nd Gen TR. Further knowledge pins between the chipset and CPU make this doable, so that you’ll be capable to grasp extra I/O off the motherboard at full efficiency.”
AMD apparently intends to assist the sTRX4 socket for the long run as it’ll encourage fanatics to put money into TRX40 mobos, understanding that they won’t have to fret about switching within the close to future. Contrarily, Intel adjustments sockets each couple of years.
Third-gen Threadripper is set to launch on November 25 with the 3960X going for about $1,400 and the 3970X at about $2,000.
