Excessive-end desktop (HEDT) processors first emerged in 2003 when competitors between AMD and Intel intensified on account of the Athlon 64 launch. Sarcastically, HEDT CPUs are actually disappearing from the market as competitors between AMD and Intel is extra intense than ever, in accordance with Puget Methods, a boutique workstation maker.
The scenario could change within the coming months, however for now many HEDT customers should get common desktop CPUs or pay additional for top-of-the-range workstation choices as AMD doesn’t appear to provide Ryzen Threadripper 3000X-series merchandise any longer.
HEDT Origins
Traditionally, HEDT processors from AMD and Intel have been geared toward demanding avid gamers in addition to professionals and, to satisfy their wants, they used silicon and packaging initially designed for server-grade CPUs, which is why they may supply not solely greater efficiency, but additionally further options (additional PCIe lanes, greater reminiscence capability). In contrast to server chips, these processors featured significantly greater frequencies but carried cheaper price tags as a result of they lacked symmetric multiprocessing (SMP) assist. In any case, all that avid gamers wanted was single-thread efficiency and excessive clocks together with giant caches did the job, not SMP.
Following AMD’s surprising launch of its first Ryzen Threadripper CPUs with as much as 32 cores in 2017, classification and positioning of HEDT chips modified drastically as avid gamers demanded processors with excessive clocks and most single-thread efficiency, whereas professionals needed CPUs with as many cores as doable in addition to wealthy I/O capabilities.
Oxymoron: Outdated HEDT Platforms
These days there are formally a number of varieties of CPUs for high-end desktops and workstations from AMD and Intel.
AMD presents Ryzen Threadripper for the so-called excessive workstations that want a great deal of cores at frequencies above and past default clocks and Ryzen Threadripper Professional for machines that want as much as 2TB of reminiscence and are usually not designed for overclocking.
At current, AMD is the one one to supply 64-core CPUs for excessive and conventional workstations, which is probably why its platform for excessive HEDTs continues to be primarily based round Ryzen Threadripper 3000X-series CPUs which can be powered by its Zen 2 microarchitecture from 2019. In the meantime, these CPUs are presently the most well-liked workstation/HEDT processors amongst consumers of Puget Methods.
With Intel, the scenario is extra sophisticated. For the highest-end dual-socket workstation the corporate presents its very costly Xeon Scalable processors that assist loads of reminiscence and have many PCIe lanes. For single-socket machines, the corporate has Xeon W-3300 collection CPUs that prime at 38 cores and are primarily based on the Ice Lake microarchitecture from 2019.
For enthusiast-grade workstations/desktops Intel has its Core X (Core Excessive) lineup that was launched in 2019 and belongs to the Cascade Lake household of CPUs. For now, Intel has nothing to supply in opposition to AMD’s Ryzen Threadripper collection so far as core depend is anxious.
As shocking as it could sound, of all HEDT platforms accessible at present, solely AMD’s Ryzen Threadripper Professional 5000WX-series relies on an up-to-date microarchitecture (Zen 3), whereas the remaining platforms are all powered by outdated microarchitectures and, in some circumstances, lack trendy I/O assist. To make the issues even stranger, Ryzen Threadripper Professional 5000WX is presently solely accessible from Lenovo.
AMD’s Ryzen Threadripper 3000X: The Departing Workstation King
Whereas AMD’s Zen 2-based Ryzen Threadripper 3000X-series CPUs are usually not single-thread efficiency champions, their 64 Zen 2 cores coupled with 128 PCIe 4.0 lanes supply unimaginable worth for workstation customers, which is why they’ve been the most well-liked workstation-grade processors at Puget since mid-2020.
There’s a downside with these CPUs although: there’s a main scarcity of AMD’s Ryzen Threadripper processors available on the market basically because it appears to be like like AMD is winding down manufacturing of its Threadripper 3000X/ Professional 3000WX merchandise, and it’s practically inconceivable for system makers to get them straight from the corporate. In the meantime, third-party resellers promote AMD’s Ryzen Threadripper 3970X and 3990X CPUs with a $1,000 – $4,000+ markup over record costs, which makes workstations primarily based on them uncompetitive.
“Loopy-high listings like that point out to me that there are solely a small variety of these chips left available on the market, and so those that have remaining inventory are driving up costs to maximise their earnings earlier than they’re gone,” wrote William George, a product improvement specialist for Puget Methods. “Because the market value of Threadripper chips is rising, not reducing, I really feel fairly assured in suggesting that they’re not being manufactured.”
To make the issues worse for Puget, costs of Intel’s Xeon W-3300 are excessive, whereas their efficiency and worth proposition are usually not as excessive as these of AMD’s platform (when chips are purchased straight from the corporate), which is why the share of Xeon W-based machines in Puget’s gross sales is simply about 4.3%.
Desktop CPUs Problem HEDT Components
However along with HEDT processors for workstations, each AMD and Intel supply superior desktop CPUs with as much as 16 cores primarily based on their up to date microarchitectures and as much as 128GB of reminiscence assist. These CPUs are adequate for the overwhelming majority of video games (as they’ll barely use greater than 16 cores) and lots of workstation workloads (in any case, not everybody does closing rendering on daily basis, however quick storage and trendy I/O are required on a regular basis). To that finish, many conventional workstation purchasers go for components like AMD’s Ryzen 9 5950X or Intel’s Core i9-12900KS.
Each AMD’s Ryzen 9 5950X or Intel’s Core i9-12900KS are primarily cherry-picked desktop components which can be comparatively straightforward to make and bin. They’re nonetheless costly sufficient to deliver substantial earnings to their respective suppliers and they’re bought in very excessive volumes to totally different audiences.
In contrast, HEDT components use server-grade silicon that may be bought at a better value as soon as certified for AMD EPYC or Intel Xeon merchandise, so making HEDT CPUs when demand for server-class {hardware} is skyrocketing and manufacturing capability is proscribed isn’t significantly logical from earnings and profitability factors of view. Moreover, even Ryzen Threadripper Professional components are bought with a substantial markup. In consequence, in some circumstances AMD and Intel could also be extra inclined to promote cherry-picked unlocked desktop components or Xeon/Professional components as a substitute of HEDT processors.
No Method Out?
Whereas, for some workloads, the 24 threads or 32 threads supplied by common desktop components is sufficient, many workstation workloads want these 64 cores/128 threads and 256GB of reminiscence, so workstation customers should go for far dearer AMD’s Ryzen Threadripper Professional 3000WX/5000WX or Intel Xeon W-3300-series processors.
Puget Methods hopes that after AMD begins quantity shipments of its Ryzen Threadripper Professional 5000WX processors, costs of those components could stabilize and/or get decrease. After all, it might have been higher for system integrators and customers if AMD launched its Ryzen Threadripper 5000X or 6000X non-Professional components, however now AMD is snug with its 64-core workstation-bound AMD Ryzen Threadripper Professional 5995WX components which can be bought with a significantly bigger margin.
Typically, the scenario with HEDT processors will probably change when Intel rolls-out its Alder Lake-X/Sapphire Rapids-X platform later in 2022 or in 2023, however now that there’s primarily a monopoly available on the market of workstation and high-end desktop CPUs, costs of such CPUs will hardly get any decrease, which is why many individuals will go for ‘common’ 16-core desktop-grade CPUs.
