AMD Announces Zen 3 Threadripper 5000, but only for Professionals
AMD today launched its first Ryzen Threadripper processors based on the "Zen 3" microarchitecture, with the Ryzen Threadripper PRO 5000WX series. Designed to be drop-in compatible with workstations and motherboards based on the AMD WRX80 chipset, these processors come in core-counts of up to 64-core/128-thread, with an enormous I/O offering that includes 8-channel DDR4 memory with ECC support, and a 128-lane PCI-Express 4.0 root complex. The biggest change over the previous generation Threadripper PRO 3000WX series has to be the use of "Zen 3" CCDs, each with 8 CPU cores, sharing a common 32 MB of L3 cache. AMD isn't using the "Zen 3" chiplets with 3DV Cache.
The full AMD PRO management feature-set from Ryzen PRO is available on these processors, including PRO Security, PRO Management, and a special support channel that includes planned parts and software availability. What's more, AMD has been working with ISVs of most professional content-creation software since the past generation of Ryzen Threadripper PRO, to optimize their software for the processors (high core-counts, NUMA topology, etc.). The benefits of these are shared with all generations of Threadrippers. Although all parts in the Threadripper PRO 5000WX series are rated for a TDP of 280 W, AMD claims to have worked on power-management, offering up to 67 percent lower power per core, compared to the competition (2P Xeon Scalable Platinum 8280).
The latest iteration of AMD PRO Security borrows from both the Ryzen 5000 PRO and EPYC "Milan" feature-sets, and mainly sees the introduction of AMD Shadow Stack. AMD describes this as a "security feature addresses threat vectors such as return oriented programming attacks. It helps by keeping a record of the return addresses so a comparison can be made to ensure integrity is not compromised. In addition, AMD Shadow Stack enables Microsoft hardware enforced stack protection." You also get AMD Secure Memory (hardware-accelerated memory encryption), and a hardware-based dynamic root of trust.
Generationally, AMD has not increased the CPU core-counts. What's changed are the increased IPC from the "Zen 3" architecture, multi-threaded performance improvements from the 8-core CCX design (all 8 cores on a CCD sharing a single 32 MB L3 cache), and generational increases in clock-speeds. All models in the series come with maximum boost frequency of up to 4.50 GHz, and preferred cores on each CCD (two cores per CCD, which can sustain the highest boost frequencies).
There are five models in the Ryzen Threadripper PRO 5000WX series. The series begins with the 12-core/24-thread Threadripper PRO 5945WX (two CCDs, each with 6 cores enabled). The processor is clocked at 4.10 GHz. The Threadripper PRO 5955WX is a 16-core/32-thread part clocked at 4.00 GHz, with two CCDs that have all eight cores enabled. The Threadripper PRO 5965WX is a 24-core/48-thread part with 3.80 GHz base frequency, and four CCDs that each have 6 enabled cores. The Threadripper PRO 5975WX is a 32-core/64-thread part with 3.60 GHz base frequency, and is made up of four CCDs with all their cores enabled. Much like the 3000WX series, AMD skipped a 48-core/96-thread part, and went straight for the 5995WX, with its maxed out 64-core/128-thread count, and 2.70 GHz base frequency, with eight 8-core CCDs. All models come with 4.50 GHz as the boost frequency, and 280 W TDP.
AMD posted a variety of performance claims against competing Intel solutions. The blue team doesn't have these many cores on a single package, and so AMD set up 2P machines of the latest Xeon Scalable parts available in the market, for its comparisons. Find the benchmarks in the slide-deck below.
As for availability, AMD did not release pricing information, because these processors will not be available in the retail channel just yet. They will be offered exclusively with the Lenovo ThinkStation P620 line of pre-built workstations. This is exactly how AMD released the previous-generation of Threadripper PRO chips. Retail availability of the Threadripper PRO 3000WX followed Lenovo exclusivity by about 3 months, which could be the case with even these chips.

That said, I don't expect Zen 4 TR to be announced this year. Maybe, but probably not.
I’d like to grab a new TR chip but they really screwed over previous buyers, twice, and eventually lagged desktop counterparts by almost a generation.
wasnt this announced already or was a leak thing?the leak was here.

Having these Lenovo exclusive for 3 months makes them essentially DOA. No business is going to build DDR4 workstations that get borderline equivalent parallelized performance as prior gen in Q3 2022.
The only folk who would've snapped all these up are the dual use buyers who want the higher IPC for occasional gaming on existing trx40 but they're not releasing for that platform.
There's a reason none of the slides show a comparison to 3000 series TR. It would be probably 12% IPC and 2% multithreaded uplift.
I'll wait until AM5 teething issues settle and then see how the 16-core compares to these TR chips and whatever Intel has at the time. It's a really bad time to buy super high core count systems.
Anyway, here it is:
AMD Threadripper PRO 5000 workstation CPUs officially unveiled: Zen 3 with up to 64 cores, 4.5 GHz clock speed and 280 W TDP
AMD has officially announced the launch of its Zen 3-based Threadripper PRO 5000 CPUs, targeting the ultra-workstation segment:
www.amd.com/en/press-releases/2022-03-08-new-amd-ryzen-threadripper-pro-5000-wx-series-processors-are-the-ultimate
Zen 3 comes to Threadripper in the form of the AMD Threadripper PRO 5000 CPU family, with no competition from Intel.
After a very long delay, the AMD Threadripper PRO 5000 family based on the Zen 3 core architecture is finally here. With up to 64 cores, the new workstation-focused chips offer up to 19% more IPC in the same package and on the same platform as the previous Zen 2-based Threadripper chips.
AMD Threadripper PRO 5000 CPU lineup
Information about AMD's Ryzen Threadripper 5000 HEDT CPUs has been leaking for some time. The lineup includes the 64-core Threadripper PRO 5995WX, 32-core 5975WX, 24-core 5965WX, 16-core 5955WX and the 12-core 5945WX. All of these chips are based on the Zen 3-core architecture, so we can expect big gains in single and multi-threaded workloads. All CPUs have a TDP of 280 W and a boost clock of up to 4.5 GHz (via a single core).
AMD Threadripper PRO 5000 CPU specifications
Speaking of specifications: The flagship Threadripper PRO 5995WX will have 64 cores and 128 threads. It features 256 MB of L3 cache, 128 PCIe Gen 4.0 lanes, 280 W TDP and offers support for 8-channel DDR4 memory with up to 2 TB capacity. Clock speeds are 2.7 GHz base and 4.5 GHz boost.
It looks like all models below the 5995WX, such as the 5975WX and 5965WX, will have a slightly disabled die with 128 MB of L3 cache. This is half of what the flagship offers. Clock speeds are 3.6 GHz (base) and 4.5 GHz (boost) for the 32-core variant and 3.8 GHz (base) and 4.5 GHz (boost) for the 24-core variant. Further down the line, we find the 5955WX with 16 cores and the 5945WX with 12 cores. Both chips have 64 MB L3 cache, a quarter of the cache of the top chip, and the clock rates are 4.0/4.5 GHz and 4.1/4.5 GHz, respectively.
AMD Threadripper PRO 5000 CPU prices and performance
In terms of performance, there is currently no competition to the Threadripper PRO 5000 CPU line. They are much faster than anything Intel has to offer in the workstation segment and deliver even more performance thanks to the Zen 3 cores.
The price is also expected to be higher than the Zen 2 lineup, which is to be expected given the price increase of the Ryzen 5000 mainstream CPUs over the Ryzen 3000 models. We've also seen some hints that AMD is going the dual-socket route for its Threadripper PRO line for workstations, which would allow up to 128 cores and 256 threads on a single x86 PC. But for now, these chips are only exclusive to Lenovo's Thinkstation P620 workstation PC. As long as they are not available in the DIY segment, the exact SKU prices still remain to be seen.

This launch will definitely give AMD an edge over Intel, which will introduce its own Sapphire Rapids HEDT family later in the second half of 2022 for the W790 platform.
Both Intel and AMD last launched their HEDT CPUs in November 2019, AMD also released its workstation/prosumer Threadripper chips, but Intel has failed to capture the HEDT market since then. With the new HEDT CPU families launching in 2022, we will once again see heated competition in this segment, especially since both CPU vendors will offer brand new core architectures for the platform.

Maybe wait until the price drops and I'll pick up a 32 core.
