AMD on Thursday formally unwrapped two new Threadripper 3 CPUs with 24 and 32 cores, respectively. The firm additionally introduced an unlocked Athlon and stated its 16-core Ryzen 9 3950X will lastly go on sale on November 28.

The two new Threadripper CPUs are the most important information. AMD will promote a 24-core Threadripper 3960X for $1,399. The chip is constructed on a 7nm course of, options 140MB of cache, and can have a base clock of 3.8GHz and enhance of 4.5GHz. The 32-core Threadripper 3970X, priced at $1,999, arrives within the wake of a lot undue hand-wringing that AMD would solely go to 24 cores.

Both CPUs will go into AMD’s new TRX40 platform utilizing the brand new sTRX4 socket. The use of a brand new socket basically means the unique X399 chipset, together with the  Threadripper 2000-series, will likely be stranded.

Insane quantities of PCIe lanes

The comfort could include an insane quantity of PCIe bandwidth. AMD stated as much as 72 lanes of PCIe can be found within the new platform. The block map the corporate confirmed off signifies 48 PCIe 4.0 lanes could be dispersed for basic use. Another pair of x4 PCIe 4.0 can be utilized for NVMe, or damaged up as two quad-clusters of SATA ports. With the chipset connection at a beefy 8 lanes of PCIe 4.0, you rise up to 64 from the CPU.

Much of that sounds the identical because the earlier X399, which additionally featured 64 PCIe lanes off the CPU. The key distinction right here is PCIe 4.0, which doubles bandwidth over PCIe 3.0.

The different distinction is further PCIe 4.0 lanes within the chipset. AMD’s block map reveals 8 lanes of PCIe 4.0 off the TRX40 chipset for basic use, and 8 extra lanes of PCIe 4.0 that may be break up off. That’s principally 72 complete—AMD touts “88 lanes” of PCIe, however that’s provided that you depend the reserved lanes for chipset communication.

Quad-channel RAM stays put

The quantity of reminiscence channels for the brand new Threadrippers additionally seems unchanged, with as much as 4 channels of DDR4 supported on each CPUs. While there had been hypothesis that AMD would go along with an eight-channel reminiscence configuration to coincide with an anticipated 64-core CPU, AMD didn’t say peep about further reminiscence channel help (which might require a further new platform) or a brand new CPU. So for now, Threadripper sticks with quad-channel reminiscence.

AMD will flex its core depend muscle tissues with Threadripper 3000.

AMD says it will be quick

AMD has lengthy had a core depend benefit over Core i9, however with the brand new, extra environment friendly Zen 2 cores within the Threadripper 3000 chips, the corporate additionally guarantees much more efficiency. For instance, AMD stated its 32-core Threadripper 3970X will likely be as much as 90 p.c quicker in Cinebench R20 over an 18-core Core i9-9980XE. The 24-core will outpace Intel’s present greatest Core i9 by 54 p.c, the corporate added. AMD additionally claims an enormous benefit over the top-end Skylake-X chip in Chromium compiles, Unreal engine compiles, Adobe Premiere CC encodes and Chaos Group’s V-Ray renderer.
