Asus Rampage 6 Extreme now has details on Asus website:

https://www.asus.com/us/Motherboards/ROG-RAMPAGE-VI-EXTREME/HelpDesk_QVL/

I was really surprised by the QVL list. For DDR 4200 there are multiple entries for 8x8GB, with G.Skill being capable of 19-19-19-39. For DDR 3800 there are also entries for 8x16GB 19-19-19-39. Those are very high and to me unexpected clocks given the number of memory sticks/capacity.

Rampage 6 Extreme doesn't support KabyLake-X, only Skylake-X.

Nope! The $1,700 6950x was Intel's best-selling HEDT chip. 15% is a big deal for those who just can't have enough processing power in this niche space. Also if you're going to go crazy and spend upwards of $5k on a new system, $700 for 15%+ more performance is bearable.

It should be pretty much most sales in the cheapest and least in the top SKU. It might be a bit different in other stores, but probably not completely opposite.

Just like zucker2k said the difference in total price is not that great. I'm also considering 7980xe, as it will be a nice cpu for VMs without compromises.

It's $700. To me that's a removed load of money.

As a consumer I guess I just can't logically justify this in any way. The more you pay the less you get for your money, wouldn't it be better to spend that money on other components instead? If you're already spending $5k on a computer why does $700 suddenly become not a big deal? Why would you spend more than you need to?

As a business, well I have no experience to go on. Say you need to buy 20 workstations for a team, do you not care that 20×700 = $14,000?

It just seems super odd to not care about value for money at all.

BTW, not saying anything about the 7980xe since we don't know where it'll fit in, it could well be worth the extra money for some use cases.

No profanity in the tech boards.

In Central Europe Intel seems to have better distribution network than AMD (less greedy) so as a result Intel gets an advantage here. A 1950X is $1300, 7900X is $1150. Official $ prices are relevant for US, but elsewhere they don't apply. Therefore 7940X will be a good competitor as price difference will be small in overall cost.

It's also very positive that 7980XE will get released much sooner than initially thought, in 1.5 months.
Wrong
Yes the 7900x 937€ is perhaps like 6-11% less expensive in eu than 1950x 1037€, but still 1950x is nowhere as expensive as a 7920x 1339€ and far closer to the 7900x. German prices.

Comparing to a non existing 7940x is just flat out nonsense.
What is this "central europe"?
Because in dk i cant find your price and neither for germany.
But who knows 7900x prices have taken a dive recent days it seems so it might change. But 7920x is still in another priceclass.

No you get an epyc 32 core for 2000 usd for that.
Its faster and if you really want high end and no compromises in speed and io.
You can get an 7980x for your vm and save a few dollars in total cost but its really the poor mans non professional solution for lots of VM.

The $14K may not mean anything. The rate at which the work gets done in specific areas may be the most important factor.
$14K might be a deal breaker, or it might be well worth it, depending on the specific circumstances.
If each task is completed 5% faster, you would get a lot more tasks done per day, and that may be worth a lot of money. Or not.

The sales list i have seen have all been like mindfactory.de
I dont know where this rumour originated from, because it consistently looks opposite when i look at sales ranks?

The problem is because you are the one who is not caring about the value for money.

Lets look at ALL of the numbers. I'll take your post using your exact values. Suppose a $5700 computer was 15% faster than a $5000 computer. Yes, you are correct that it cost $700 more to purchase.

But, suppose that computer is running software that costs $10000 per year (which is actually fairly cheap, specialized software often costs $20,000+ per computer per year). The amount of work that the $5000 computer does in 1 year, the $5700 computer could do in 0.87 years (15% faster works out to needing 13% less time). Thus, you only need to pay $8696 for the software to do the same amount of work. The $700 faster processor saves you $1304/year.

Even more importantly the engineers running that software have a salary + benefits that are probably close to $100,000 / year. That engineer that took 1 year to complete a study with the $5000 computer only needs 0.87 years with the $5700 computer. Again, you save $13,043 in engineer time.

That ONE TIME purchase of $700 saves the company $1304+$13,043 = $14,348 PER YEAR.

It gets bigger when you look at teams. Look at just your 20 workstation cost: 20 * $5000 workstations cost $100,000 and the software costs ~$20 * $10000 / year = $200,000 / year. But that same amount of work could be done with just 17 workstations with ~15% faster processor. Thus you need 17 * $5700 = $96,900 in computer costs. It actually is CHEAPER to buy the team the faster processors. And considering the software, you save $30,000/year. That is even if you don't consider employee costs.

No one in business that needs this type of power should ever think that a mere $700 more for a 15% boost is even worthy of consideration.

Does 1950x run 3,7GHz on all cores stock? I thought its just 3,4 and the 4Ghz on just 2 cores... or 4 cores...whatever. Bottom line, nothing in between.

7920x looks good. I guess simple activation of MCE in BIOS, overclocking all cores to 4,3 and it matches Threadripper even there, where it trails it at stock - like Cinebench.

In Germany prices will naturally be lower as its a bigger market and higher elsewhere. I'm not going to buy 20 computers, just one. For now ignore 7920x at 1339€, it will come down gradually too.

For me computer is like a car. I expect it to last for 5+ years. But unlike cars computers don't rust and don't need maintenance. They are much less troublesome. People spend a lot of money on cars, why not computers if you use them daily? I have no problem to pay $1000+ for a CPU as I do not upgrade frequently.

Talking about Central Europe and prices, 7900x is here (in my prefered e-shop, czech based, but for entire Czech Rep and Slovakia) is 946 euros, 7920x is listed at 1134 euros, TR 1920x is so far @ 850 euros and TR 1950x 1072 euros. Not sure why 7920x is so expensive in Germany, but it will sure come down close to expected price once it hits the shelves. Hopefully even lower

I had a look and for some reason I though Epyc was 2P but I was mistaken as there is a 1P version available too.

I'm not quite convinced that the team would be utilising the CPU to 100% at all times, which is what this argument assumes.

As a software developer I'm not literally constantly compiling software all day. It would be interesting to see some real world numbers of daily utilisation, but I suspect outside of some very specific use cases that none of this actually matters and the cheaper CPU would still be cheaper.

Yep the EPYC 7551P for 2100 usd. Its lower freq processors than hedt but still within the 180w tdp. Different purpose but for multiple VM looks like a clear winner to me.

Now we need the most important spec that is missing,
PRICE
Yeaa
I am really looking forward to this beast. Its got a clear purpose for my gaming load unfortunately i am not the only one so there will be a huge mining like demand. Lets hope for 7700k price.

How are there no compromises? If you determined that you need about 18 cores in your VM host, then there are other Intel based offerings which give you
  • higher memory capacity,
  • more memory bandwidth,
  • ECC memory,
  • more I/O,
  • lower lifetime cost by better performance/Watt (unless you underclock and undervolt the XE),
  • lower purchase cost if you consider the 2nd hand market,
  • or several of the above.
There is a single feature of 7980XE which cannot be found in competing Intel processors, which is somewhat higher clocks during low and medium processor utilization. But even this feature is naturally tied to a compromise: Middling performance/Watt.

Clearly if you compile 3 times a day for 10 seconds each time, then saving yourself 4 seconds is not a case in which you need these chips. You would be much better off with a cheap chip and few cores.

I was speaking of situations in which you actually need this power. Think simulations that take hours/days/weeks to run with the CPU at 100% usage all the time. This is where you really need HEDT. And it is a very common use case (aerospace simulations, fuel efficiency of cars, structural support of high-rises, nuclear reaction simulations, defense calculations, biological structure simulations, chemical production calculations, design of CPU coolers, etc).

This is a more extreme example, but there are uses where people took the time to benchmark 18,432 cores running a single calculation for a wheel design:
http://www.ansys.com/Solutions/Solu...se-17/external-flow-over-a-formula-1-race-car
Think of the cost saving of needing 15% fewer computers in that simulation. Also due to Amdahl's law, they wouldn't have dropped from 80% efficient to 68% efficient and thus probably need closer to 26% fewer computers if only they had chips that were 15% faster.
