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 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.
The Core i9-9980XE isn’t Intel’s prime prosumer chip, although. The firm announced its new Core i9-10980XE at crazy-low prices in early October. While the older 18-Core i9-9980XE nonetheless sells for $1,919 at present on Amazon.com, the brand new 18-core Core i9-10980XE will promote for $979.
In an odd flip of occasions, with Intel’s loopy worth cuts in place, AMD’s new Threadripper will truly occupy the upper floor on pricing. If you utilize the overly simplistic metric of greenback per thread, Intel truly has a bonus in a Core i9 vs Threadripper worth match. Of course, from AMD’s viewpoint, it most likely thinks Core i9 can’t even dangle with its Threadripper anymore and would slightly see its $750 16-core Ryzen 9 3950X duke it out with Core i9 at present.
Ryzen 9 3950X: Coming quickly, with Eco Mode
Here’s the opposite large announcement: The long-awaited, barely delayed 16-core Ryzen 9 3950X will go on sale on November 25, the corporate stated. Pinkie-swear. The CPU had been anticipated in September, however was pushed again to November. AMD has taken that point so as to add characteristic known as Eco Mode.
Eco Mode will allow you to scale the CPU again from its rated 105-watt TDP to 65 watts. There is a efficiency value: AMD stated Eco Mode will get you about 77 p.c of the efficiency of the usual mode, however at 44 p.c of the facility consumption and in addition about 7 p.c cooler. AMD stated Eco Mode could be turned on and off from inside a brand new model of the Ryzen Master utility.
The firm stated the mode was added by request from customers who wish to use Ryzen CPUs inside residence theater PCs and different environments with restricted thermal and noise headroom. AMD is casting a large internet, saying the brand new Eco Mode will apply to different 105-watt Ryzen-based chips. Eco Mode may also enable 95-watt chips to drop to 65 watts, and 65-watt CPUs to drop to 45 watts.
AMD took the chance to drop extra hints about how a lot of a thrashing the CPU will give to its rivals. Of course, the comparability is pretty shut in opposition to Intel’s $500, 8-core, Core i9-9900Okay, however AMD stated it’ll thrash the 12-core Core i9-9920X, which sells for $1,000.
Content creation would be the 16-core Ryzen 9 3900X’s forte. The $500 Ryzen 9 3900X already had the Core i9-9900KS on the ropes for multi-threaded and most content material creation duties, so the 16 core? Yeah, it’s only a victory lap at this level for AMD.
An overclockable Athlon, too
Not everybody can afford a $2,000 32-core Threadripper 3970X or a $750 Ryzen 9 3950X, so AMD is throwing funds PC customers a bone: an overclockable Athlon 3000G.
The Athlon 3000G will characteristic two cores with symmetrical multi-threading, and Radeon Vega 3 graphics, for $50. The chip can have a clock frequency of 3.5GHz and, sure, you may overclock it.
AMD envisions the Athlon 3000G going up in opposition to Intel’s $60 dual-core Pentium Gold G5400. Although AMD didn’t element its structure, the Athlon 3000G is probably going a Zen+ chip constructed on a 12nm course of. That’s nonetheless sufficient, AMD claims, to place it forward of the Pentium Gold G5400. AMD stated its exams present the Athlon outperforming the Pentium in boring desktop use, and simply outrunning the Pentium Gold in gaming. AMD stated the brand new Athlon 3000G will go on sale November 19.
