MS architects were too narrow mind when they allow so much in Win.
1. Any app can intercept keyb focus. WHY?? I'm busy w Word, I don't give a hell IE cannot connect internet! But no, idiotic message will appear above the word and annoy me.
2. Any app can intercept DLL calls. THANK YOU for this Mars-size hole, MS smarties!!
3. Global keyb shortcuts. Again, nobody use 'em! Who the hell will remember all those Ctrl+Alt+FCKMETWICE, especially when they can be THE SAME in different app??
MS are such a clowns!

So a couple of years ago, I was invited to participate in a Dell video meeting survey, where they asked me questions about Dell Precision products, and after I bought a Dell Precision 5920 with a Xeon chip, I told them I couldn't believe they didn't offer a AMD Ryzen version of the Precision with 5nm technology, and why I had to buy the Intel with 14nm technology. Anyways to my surprise, they made it!
I'm looking at the new Dell 7875 with the AMD Ryzen Threadripper PRO 7955WX CPU, and a RTX A4000 card. But I was looking at the power consumption, and it kind of looks like it's about 1.3K watts of power, which raises questions for me about it. I get that at full load, it can peak to say 1000 watts or even higher, but 50% of my work is just typing code and testing it.
I know many here built one of these custom rigs with similar specs over the last 3 years, and are very happy with them, but no one ever mentioned the power consumption part.
Are these AMD Ryzen systems power on demand, like very power efficient at idle, but can ramp up at load? Or do they idle at say 100 watts, 50 watts, and come pretty close to Xeons W Series?

I built a second generation threadripper machine with the top-end 32 core chip, and my electric bill increased two fold.
Just kidding, of course. But I do observe that 30 out of the 32 cores are listed at 0% usage when the machine is idle.
The difficult we do right away...
...the impossible takes slightly longer.

I couldn't find a review of the 7955 but I found one of the 7980 : AMD Ryzen Threadripper 7980X review (Page 6)[^]. The link is to the page that discusses power consumption. It appears that they are power-on-demand and consumption will ramp up when needed.
I would make sure you will really need a 7955. I work on an industrial HPC project and I did a benchmark with my application. It is scalable so it can use as many threads as are available. I found that the Ryzen 7950X (16 cores and 32 threads) was the fastest for it. Here are the results I obtained :
i7-10870H 60.4 8 cores, laptop
i7-11800H 55.9 8 cores, laptop
EPYC 73F3 (x2) 51.6 64 cores
TR 5975WX 50.1 64 cores
Ryzen 5900 49.5 12 cores
Ryzen 5950X 40.1 16 cores
Ryzen 7950X 32.6 16 cores
The 7950X won primarily due to its high clock rate. We deploy those for our systems these days. In my opinion, unless you need to run a ton of threads and your applications are not particularly CPU-bound then I would go with the Ryzen 7950X. They are really, really fast. I use a 5950X at work and a 5900 at home and I really like them.
BTW - one thing that really surprised me with the benchmark was how my laptop is almost as fast as the EPYC system. It is a 2022 model with no e-cores and the EPYC system is actually clocked slower than its boost mode.

I'm no expert for workstations but this one looks like a system for extreme situations like high end CAD and high end Graphics.
Perhaps for writing game apps useful.
But for just typing code and compiling for testing this code - for me such a system seems totally overpowered.

Is it? If a developer has to write a game on a less powerful machine isn't it more likely to run well on a less powerful machine?

Perhaps he meant the C++ compilation time

Allow me to be the second person to wonder what you need that kind of horsepower for when it comes to development.
Those threadrippers are no joke. I have two high end consumer/gaming CPUs (unlocked) on my desktop and laptop and they do everything i need and then some. I don't even know what I'd do with a threadripper.
So are you sure you need it? Modern high end consumer processors are plenty fast these days.
I've got an i5-13600K desktop with a 4080 GPU, and an i9-13900HX with a 4090m GPU.
IMO, they're both overkill, at least right now, but they'll keep me happy for some years.

This was my thinking.
CAD and 3D modelling stuff, rendering, real-time physics simulation, maybe some specific types of AI (probably not very good for ML stuff - most of that targets GPUs), they're workhorses for sure.
They're just not real cost efficient except for a pretty small subset of people with lots of massively parallelizable workloads they're constantly running.
Someone built a crazy one and posted pics to Reddit awhile back. I think that behemoth sported 2xthreadrippers and something like 1 TB of RAM.
People pressed him for wtf he did with that thing.
He designs/prints custom anime waifu pillows.
P.S. do not get if you want to game - they can totally do it, but as you can imagine, this is not a setup developers test or care about if it does not work

To all:
I was wondering the same thing about do I need that much power? When I was shopping or looking, the Dell 7975 was the only model with AMD that I can find ($7300). But I looked again today, and clicked on Deals or Bargains and found the older Dell 7965 model with the ..
AMD Ryzen Threadripper PRO 5955WX (64 MB cache, 16 cores, 32 threads, 4.0GHz to 4.5GHz, 280 W) - 1 CPU step up from the bottom. It's $900 more for the AMD Ryzen Threadripper PRO 5965WX (128 MB cache, 24 cores, 48 threads, 3.8GHz to 4.5GHz, 280 W) and seems like a lot more money.
(Dell 7965) for 1/2 the price, which seems more realistic to me, price and affordability as well ($3600).
I wasn't really sure just how much computing power the Dell 7975 has, but it looks like I could design a winning Formula one engine, or create an animated movie with it and that would be overkill for me. I just want to be able to use Avid Media Composer to make YouTube videos on car repairs, and edit 4K video, plus write code.
On the side: I have my old Dell T3600 that I bought in 2011, I took home last year for my new home office, and I miss the power I have at the work office, plus using Windows 11. I do more intense computing at home and would like something more powerful than what I bought in 2022. I'll buy the Dell 7865 instead, and that should last me a long time.

I bought the Dell Precision 7865 Tower Workstation, with the Ryzen 5955WX, 1 TB boot and 64 GB Ram with the RTX A4000. I was skeptical over the price offered by my Dell Rep, $3249 total, for a Lenovo 620 same config was $4600, Dell 7865 with same config at BH Photo was $4866. After I bought it and saw the order details, it's like Dell gave it to me near cost. It's amazing how fast technology advanced over the last 3 years, and this computer seems to have been outdated in less than 15 months, and now on clearance. Gonna be nice to have a modern computer at home that is a little more powerful than what I bought in early 2022, a 10 core Xeon with same specs for about $3200.
Hey, thanks for the input on power consumption, and talking me out of the new Thread Ripper or 7000 series considering my use for the computer. That would have been overkill for me, and perhaps require me running another dedicated 15 amp circuit from the panel to the computer in the garage. I just upgraded my garage late 2022, with new LED lights, 4 more circuits, repair and finished the drywall and new primer and paint, and I'm done with that can of worms.
On a side note, on Xmas day I decided to put together the iPhone app that my friends have been bugging me about for years, and spent hours setting up for it, to find at the end I needed a Mac if I wanted to use React Native with Expo, over .Net Maui, so I bought a Mac Mini that night. I have a iPhone, iPad and watch, but I don't have an Android phone, and I had to laugh  I really wanted to upgrade my home computer (2011 6 core Xeon), and wasn't considering a Mac, but this Dell deal made both possible for the price of just one high end build.

These machines are all "power on demand". I run a 13900K with an overclocked RTX 4080 and it can hit 760W for very brief periods. Typically, my machine idles at 250-ish watts and games at 540-580W.
Assuming a US house, if you floor that gas pedal and reach 1,300W, keep in mind that's just under 11 AMPS at 120V AC, single-phase.
That number doesn't include the rest of the motherboard, monitors, or anything else you have attached or on the same circuit. You're going to have to keep that stuff in mind because you might run into the 15A limit for your typical household circuit breakers. Depending on your house wiring and other stuff on the same circuit, you may have to run a dedicated circuit just for the machine!
Oh, and if you're considering a UPS, keep in mind that your typical household 1500VA UPS will NOT WORK as they top out at 900W. You'd have to look into commercial units and professional wiring to supply it.
Best of luck on that power bill!

not sure what your application is, but I can give you a GREAT deal on a machine like this - 3 ssds (5 TB) , rugged motherboard and a 2060 graphics card... oh 64GB of ram too.
It's used - but very lightly so... email me - cgilley@bravesw.com
I'm in career transition and I'm getting rid of toys that I really don't need. I tend to REALLY do good motherboard and power supply research.

I'd consider it, but this is a tax write off for me, and it's easier for me to write off a new canned system and depreciate it over a custom built system when I Schedule C this purchase for 2023.
I just use these things as tools now, and this purchase gives me insight into some of the stocks that I own, to get a better understanding of where technology stands today and where it's going in the future. It's a tax and investment strategy for me, and a research tool. But thanks for the offer!

I can see a slew of lawsuits on the horizon, but will you be able to trace who created the AI or did it create itself and it that case??

" ... do not copy or store in a retrieval system ...". There's the rub.
The "discovery" phase will force them to show their "training data".
"AI" is so "expensive" because it's constantly "structuring" unstructured data from "documents" that it "copied".
