AMD Ryzen Threadripper 3960X With 24 Cores & 48 Threads Confirmed, Naming Scheme For The 3rd Gen HEDT ‘TR4+’ Lineup Detailed
It looks like AMD's naming scheme for the 3rd Gen Ryzen Threadripper processors is out of the bag as the first 24 core and 48 thread variant has been confirmed through a listing in the AOTS benchmark by TUM_APISAK.
AMD Ryzen Threadripper 3960X '3rd Gen Zen 2 7nm' CPU Rocking 24 Cores and 48 Threads Spotted in AOTS Benchmark
AMD confirmed last month that their 3rd Generation Ryzen Threadripper CPUs would launch in November alongside the 16 core / 32 thread Ryzen 9 3950X flagship mainstream processor. The AMD Ryzen Threadripper family would premier with a 24 core and 48 thread variant but the most interesting thing about this chip would be the fact that it will be based on the new 7nm Zen 2 core architecture and a chiplet design similar to the 2nd Generation of EPYC 'Rome' processors, offering more I/O, more cache, more bandwidth and stellar multitasking performance with an insane 15% leverage to IPC over existing Zen+ cores.
The codename or naming scheme for the new Threadripper processors wasn't revealed and we were just told that it would be the 3rd Generation. However, the naming scheme seems to have leaked out in Ashes of the Singularity benchmark where the 24 core and 48 thread processor is listed as the AMD Ryzen Threadripper 3960X. This naming scheme is not only interesting but also gives us an idea of what the rest of the lineup would be like. In similar news, unreleased 3rd Gen AMD Ryzen CPUs were spotted yesterday which included desktop Threadripper chips, following is the list:
- DT Ryzen Threadripper 280W SP3R3 (16C)
- DT Ryzen Threadripper 280W SP3R3 (32C)
For starters, AMD already launched a 24 core and 48 thread model with their Zen+ based 2nd Gen Ryzen Threadripper lineup. It was known as the Ryzen Threadripper 2970WX but with the 3rd Gen line, we can see that the Threadripper **60X variant has got the same core config which shows the step-up for each respective product generation in terms cores and threads. If AMD was to launch a Ryzen Threadripper 3970X/WX, it would probably feature 32 cores and 64 threads. Similarly, a 3rd Gen Threadripper 3980X/WX would feature 48 cores / 96 threads while the flagship 3990X/WX may feature 64 cores / 128 threads.
It will be an interesting choice indeed and the naming 3960X naming scheme does remind me of another HEDT chip but not from AMD but their HEDT rivals, Intel. The Intel Sandy Bridge-E based Core i7-3960X that launch back in 2011 was an iconic chip, being Intel's first X-series product. Well, that was back in a time when 6 cores and 12 threads based on a 32nm architecture rocked the party and AMD didn't even have their own HEDT line in the play. Now we are in the era of massive core counts with Intel offering up to 28 cores and AMD offering up to 32 cores on their currently released flagship HEDT CPUs.

AMD Ryzen Threadripper 3000 Series CPUs - Here's What To Expect In Terms of Price, Specs, and Performance
The AMD Ryzen Threadripper 3000 series family is internally known as “Castle Peak” and is stated to bring dominant leadership in the HEDT market. The family will prove to be a new watermark in performance and overall efficiency while new platform features will be introduced on the new and enhanced TR4+ motherboards which are rumored to feature a revised socket and a new chipset that would restrict compatibility of older processors on the new platform.
Currently, reports state that there will be two separate platforms for enthusiasts and workstation chips, the TRX40 and WRX80. The details of these platforms are listed below.
AMD TRX40 'Enthusiast' Ryzen Threadripper 3000 Processors
The TRX4 HEDT platform would feature quad-channel memory, UDIMM memory support with 2 DIMMs per channel and up to 256 GB of capacity per channel. This means that the platform will support up to 1 TB of memory. There would also be support for 64 Gen 4 PCIe lanes with 16 lanes switchable with the SATA interface. There also seems to be info regarding TDPs and we can also notice the segmentation here too. The Group 'A' series processors, which are the HEDT lineup for the TRX40 platform with 280W TDP, Tcase Max temperature of 60C and Tctl Max of 100C.
AMD WRX80 'Workstation' Ryzen Threadripper 3000 Processors
Now coming to the WRX80 series, we are looking at a pure workstation lineup. Even the processors built around this platform are spec'd similar to the EPYC 7002 variants, featuring 8-channel DDR4-3200 support in UDIMM, RDIMM, LRDIMM flavors. The platform would support 1 DIMM/channel featuring support for up to 2 TB of memory. There wouldn't be any OC support like the TRX40 series but you get 96-128 Gen4 PCIe lanes with 32 switchable lanes to SATA. The Group 'B' series processors which are the workstation lineup for the WRX80 platform will also feature a 280W TDP but different temperature range of Tcase Max temperature of 81C and Tctl Max of 100C.

|Max L3 Cache||32 MB||64 MB||256 MB|
|Chipset||X399||X399||TRX40, TRX80, WRX80|
Considering that AMD would want to remain in a dominant position with the Threadripper 3000 series, we will be looking at some spectacular amounts of multi-threaded performance numbers which will only get better with the added clock speeds thanks to the 7nm process node. The CPUs will also be getting major core bumps, but AMD would like to keep prices close to current levels.
Some of the leaker performance benchmarks that we have seen so far (#1, #2, #3) put the 32 core variant up to 70% faster than the existing Ryzen Threadripper 2990WX 32 core chip with a average bump of 35% in performance.
AMD CEO Dr. Lisa Su:
“You know. it’s very interesting, some of the things that circulate on the Internet—I don’t think we ever said that Threadripper was not going to continue—it somehow took on a life of its own on the Internet,” Su said, speaking to a small group of reporters following her keynote. “You will see more [Threadripper] from us; you will definitely see more.
If mainstream is moving up, then Threadripper will have to move up, up—and that’s what we’re working on.”
If we look at the trend with AMD's jump from Ryzen Threadripper 1000 to Ryzen Threadripper 2000, we saw that the new processors with core parity of the previous generation were priced around the same with a $200-$300 shaved off from their previous price tag. The 1950X became 2950X and cost $200 US less. The higher core count parts were at a different market tier entirely, costing north of $1200 US but at the same time, much cheaper than their Core-X competitors.
In terms of raw performance output, the new die layout remains to be tested, but since it is more refined over the previous two generations with a stronger interconnect between them, the cache and latency performance may end up giving a bigger boost to total system responsiveness. AMD will definitely be aiming for both LGA 2066 and LGA 3647 lines with their new chips. Intel has said that their upcoming Core-X series will offer a much better value proposition with 2x better perf per dollar compared to Skylake-X, but that remains to be seen in real-world benchmarks and reviews.
