The high-end world of desktop computers has occasionally confusing terminology.If you're looking at spec sheets for some high-end CPUs, the term "HEDT" may occasionally come up with workstations and servers.


The lines that separate things like HEDT computers and workstations can be blurry.After all, they're all aimed at similar users, and they're all niche products.But what exactly is a HEDT computer? What's the difference between a HEDT and a workstation?

What is a HEDT computer?


HEDT is a short term for "High End Desktop".As an extension, HEDT pretty much means high-end computer by this definition, but it's not quite the end.After all, many consumer PCs are also considered high-end, so if we're judging by that wording alone, it's a rather vague term.

Intel coined the term to refer to a chip lineup that is a notch above its standard consumer chips but below its workstation/server lineup.They have more cores, high clock speeds, and high price tags.

However, they don't have many features that make them suitable for installation on a proper workstation or server.They're made for enthusiasts who want to get some work done, not for corporate use.

The Intel Pentium 4 Extreme was the first chip to get the HEDT ball rolling.The processor doesn't have multiple cores, but it has hyperthreading and an extremely high clock speed, 3.4GHz to be exact.

Over the next few years, with the release of the Intel Core lineup, the focus of the extreme-edition CPUs, which later became the Intel Core X, shifted to providing a large number of cores for multi-threaded tasks.The "Extreme Edition" branding, though, should let you know who these CPUs are for: enthusiasts who don't mind paying more for more performance.

Finally, AMD also introduced a family of HEDTs, dubbed Threadripper.It initially had 16 cores, but over time it went to 64.

What is the difference between a HEDT computer and a workstation?


These differences may seem subtle, and to be fair, they are. Both HEDT and workstation chips are geared toward expensive computers, and they're for those who want to do more complex jobs.However, there are subtle differences in how they actually function, as well as differences in pricing and marketing.

As we mentioned before,HEDT CPUIt is sold to enthusiasts.Not the kind of enthusiast who wants their games to run well, but the kind of enthusiast who wants to run benchmarks, do video editing, code compilation, or other CPU-intensive tasks.

In a way, HEDTs are home workstations that don't need to be used in a corporate environment.They have avant-garde marketing and don't cost as much as equivalent workstation or server chips.

On the other hand, workstations also handle CPU-intensive tasks like HEDTs.However, they are equipped with features that are more suitable for corporate environments and will not be used by people at home.

For example, it is not uncommon for workstation chips to support a large number of PCI Express lanes. AMD's Threadripper Pro lineup has 128 PCIe lanes, while its standard Threadripper HEDT lineup has 64.They also support more memory, up to eight channels of memory, whileHEDT CPUQuad channel memory is hardly supported.

In a nutshell, HEDT CPUs are generally skinny versions of workstation chips.They're just as powerful, but they lack some features that users may not need, allowing you to save money while still having a lot of the performance of a workstation.

Simply put, a HEDT is a home PC with workstation capabilities.

Should I have a HEDT?


Right now, there are some struggles going on in the HEDT space.

It's been a while since HEDT CPUs last appeared on the market.The 10th Gen Intel Core X was released in 2019, and the XNUMXrd Gen AMD Threadripper chips were released the same year.Both consumer and workstation chips have been released since then, so it's definitely just a slack in the HEDT space.

Not only have Intel and AMD stopped upgrading, but existing chips on the market also appear to be disappearing from store shelves. The 64-core AMD Ryzen Threadripper 3990X is launching at an MSRP of $4000.

But if you look for these chips on eBay, they're between $5000 and $8000.And this includes used CPUs.

There could be many reasons for this to happen.Custom PC maker Puget Systems speculates that the reason may have to do with the fact that low-end consumer processors have gotten so good that demand for HEDT chips has diminished.

After all, both AMD and Intel have CPUs with up to 16 cores, which is more than enough for most workloads that non-enterprise users need.If you really need more, both Intel Xeon W and AMD Threadripper Pro chips are available for your workstation.

Another reason could be that HEDT chips will eventually compete for resources with workstation and server chips.After all, chip shortages have made things more difficult, and the companies may have decided that more expensive workstation and server chips could be more profitable than more affordable HEDT chips.

As for whether you should buy one, we won't say that.There aren't any related HEDT chips on the market right now, and even if you're willing to pay a pretty high price for it, you're leaving performance on the table by using a HEDT chip instead of buying a workstation or even a high-end consumer chip.

A dying segment

HEDT CPUs are usually a good choice for those who can afford to buy them.They allow you to get the performance and power of a workstation and take away all the business features you wouldn't use on a PC.However, this is a segment that appears to be dying.

If AMD and Intel put some love into the HEDT space, we'd definitely recommend getting one if you need it.However, since the latest HEDT chips were introduced a few years ago, we can't recommend them -- you'll get better mileage from newer high-end consumer chips or workstation processors.
