AMD’s powerhouse Threadripper chips are again for desktop PCs! Despite declaring the end of consumer Threadripper chips final era, AMD introduced three new Ryzen Threadripper 7000-series chips on Thursday, with as much as 64 cores and 128 threads — and the choice of putting in a “Pro”-class Threadripper 700 WX sequence for an enormous 96 cores and 192 threads, too.
Take a deep breath, although. The underlying message is identical as when AMD launched the Threadripper 3970X back in 2019: these chips are for many who stay and breathe video modifying and content material creation, and are optimized for such. Nevertheless, they virtually definitely signify probably the most highly effective CPU you should purchase on a desktop, for no matter objective.
“We heard you; we are bringing it back. It’s as simple as that.”
The key variations between the older workstation-class Threadripper 5000 series and these new 7000-class processors are easy: AMD has introduced ahead its Zen 4 structure into Threadripper alongside a better core depend, quicker increase frequencies, and a generational leap forward to PCI Express 5.0. Consumers will want new motherboards, although, as the brand new “TRX50” client Threadripper platform makes use of the brand new AMD TRX50 HEDT (high-end desktop) chipset and sTR5 socket. And did we point out they devour (gulp) 350W of energy?
In some methods, although, the brand new Threadripper 7980X, 7970X, and 7960X client Threadripper choices are acquainted. They persist with AMD’s tried-and-true 64-core configuration, the identical because the Threadripper 5000 sequence, shifting right down to 24 cores. The 12- and 16-core configurations have been trimmed off from the prior era.

“We had thought we could give the market the coverage it needed, just by simplifying it down to a single platform,” mentioned Donny Woligroski, senior advertising supervisor for client processors at AMD. “There was a lot of feedback a lot from consumers who needed specific solutions, and a lot from just fans who wanted access to a high-end desktop platform. We heard you; we are bringing it back. It’s as simple as that.”
Here are the configurations of the brand new chips, which might be that can be purchased on Nov. 21. Note that AMD isn’t disclosing the costs of the brand new Threadripper chips presently.
- AMD Ryzen Threadripper 7980X: 64 cores/128 threads, 3.2GHz base/5.1GHz increase, 256MB L3 cache, 320MB cache whole
- AMD Ryzen Threadripper 7970X: 32 cores/64 threads, 4.0GHz base/5.3GHz increase, 128MB L3 cache, 160MB cache whole
- AMD Ryzen Threadripper 7960X: 24 cores/48 threads, 4.2GHz base/5.3GHz increase, 128MB L3 cache, 152MB cache whole
All of those new consumer-class Threadrippers 7000 processors devour 350W and permit for overclocking. (OEM techniques in all probability gained’t enable overclocking, AMD executives mentioned.) They additionally embody 4 channels of DDR5 RDIMM reminiscence with error-checking and 48 lanes of PCI Express 5.0 I/O. (A complete of 88 usable PCIe lanes, together with PCIe 3, seem on the platform.)
The 4 channels of reminiscence are vital, as AMD’s earlier Threadripper choices supplied eight, in all probability overkill for a client design.
The new Threadripper platform tweaks the older design. The Threadripper 5000 platform collected eight cores inside a single CCD, sharing 32MB of cache, with a complete of as much as eight CCDs (for 64 whole cores). The Threadripper 7000 platform maintains the eight-cores-per-CCD design, however will increase the shared cache to 32MB per CCD. The elevated variety of cores additionally necessitated extra CCDs: as much as 12 in all with the Pro chips (for 96 whole cores). AMD’s Infinity Fabric Gen 3 helps tie all of them collectively.
Interestingly, AMD’s new Threadripper Pro lineup makes use of the identical sTR5 socket because the desktop fashions, although the Pro lineup is versatile: these chips can both use what AMD calls the Pro platform, or the HEDT platform. A deep-pocketed fanatic might conceivably purchase one of many new 4 Threadripper Pro fashions to be used in a client system, however they’ll lose out on the Pro platform benefits: 8 channels of reminiscence as much as DDR5-5200 (for a complete of as much as 2TB of reminiscence), 128 PCIe 5 lanes (or 144 usable PCIe lanes in whole) and AMD’s manageability options.

The new, bigger socket would require new cooling options, too. AMD mentioned it could have an inventory of authorized cooling options nearer to launch.
Threadripper efficiency: superior, as anticipated
The transfer to AMD’s Zen 4 structure will embody a generation-to-generation efficiency enchancment of about 13 % by way of directions per clock, AMD executives mentioned, together with help for AVX-512 directions. Naturally, AMD is evaluating its new Threadripper 7980X chips to the Intel Xeon, and never a Core chip, the place it’s claiming between 4 % (Keyshot) to 94 % (Metashape) enchancment over the 56-core Intel W9-3495X.

While AMD is primarily specializing in content material creation because the chief promoting level for the Threadripper household, executives did counsel an alternate: AI coaching. When we discuss client AI, we often discuss “inferencing,” testing an AI giant language mannequin by asking it to assemble a brief story or piece of AI artwork. But the opposite part of AI is coaching, or instructing the algorithm.
Though a college examination might be accomplished in an hour or so, really studying the fabric is rather more time- and resource-intensive. So it’s with AI — and this machine studying often takes place behind the scenes, with server farms over lengthy durations of time. Machine studying is often related to highly effective server processors backed by gobs of reminiscence capability, capabilities that the brand new Threadripper chips strategy. AMD is claiming that customers can obtain 189 % extra accuracy when utilizing the Meta’s LLama-2 mannequin with 70 billion parameters.
We’ve included AMD’s abstract of each its Threadripper 7000 and Threadripper Pro 7000 processors, under, together with AMD’s personal abstract of how they evaluate to Intel’s Xeon chips.

Should you anticipate to see a Threadripper system in your native electronics retailer? Probably not. But if you happen to’ve been saving your paycheck for a 12 months or two, who is aware of? You could possibly decide one up once they begin transport on Nov. 19.
