Disappointing benchmarks for i9 7900x

I was browsing UserBenchmark the other day, and came across some pre release benchmakrs of the 7900x and 7920x. 7900x, being the 10 core thing it is, scored a surprisingly low 5th place. How could that be? It has specs to almost match the 6950x, after all. Btw, 7920x stole 1st from the 6950x, but its 12 core, though.

when you can't buy new cpus because manufacturer didn't made more, ram support starts to move on to faster modules for newer platforms and you can't find new mainboards from any manufacturer and all you find is old expensive models, the platform is dead

intel likes to do this each 2 years more or less, it is the turn for that platform

i wouldn't invest a single cent on a platform knowing that, especially with the 1300 dollars price of that cpu you want to buy, that needs a already obsolete x99 mainboard that is as expensive as the cpu

they killed his current platform and made unpayable their new lineup, that is why i say wait, they have to adjust to the new reality, where threadripper hasn't been released and have everybody excited...

well, a new cpu without proper support can do that

but in general, it seems that intel just released alot of unused middle/low quality server parts and hoped for the best on this new platform that no one seems to like

it is not working, is what most people are saying, time will tell, perhaps optimizations make them usable, at 2000 dollars...

I was referring to the X299 platform i9 cpus, about to be released this month,

I agree completely. Normally when Intel releases a new line of Cpus they are practical and well received. I am just not buying the idea of these i9s. I mean, if they offer the same core count and faster speed than the 6950x at half the price, Intel must have cut corners elsewhere, that will only be visible once people start using the chip.

It is only a week or two from release. This sample must be the final one. If it performs like this on day one, I may opt for the 6950x instead, regardless of whether optimisation makes it better over time, as I am building a pc within the coming 2 weeks.

This happens a lot.
Ryzen, initially:

Woe be to him who blindly jumps into a whole new product on day 1.
Let the other fools spend money and find the problems.

Would you then advise me to buy 6950x over the 7900x?

Depends on how soon you need it, and your actual usage.

I wouldn't buy an i9 for at least a couple of months after release. Or any other brand new lineup.
CPU, GPU, RAM, whatever....

The i9 may or may not become a great CPU. It will almost certainly end up really, really good. Time will tell.
But if I were building something in the next 4 weeks...it wouldn't be an i9 based system.

Thanks for the clarification, I completely agree. I will now confidently buy the 6950x. I am sure it will hold up for at least 3 years. Its a 10 core monster, I dont see it becoming obsolete in the next 3-5 years.

By the way, I think the only i9s that could really perform better (not on par, but better) are the 12 core and up versions. However, I doubt many people would want to buy those, as modern computing tasks find 10 cores sufficient. Diminishing returns, as they say. 10 cores is also probably in the diminishing returns zone.

i wouldn't buy any intel now

you need to wait to see how the dust settles

the new x299 effectively kills x99, so the 10 c0re beast is the last beast that will exist for x99, so you will buy a dead platform

wait for price cuts, you might end with a ryzen cpu and happy with the results

The platform will only be dead in the sense that it is no longer the latest. However, in terms of performance it will remain excellent for the next few years. Am I right in believing this?

And the alternative is to fall into the AMD realm, and live with no real platform or performance updates for 5 years or so?

A system is only 'dead' when it no longer does what you need it to do.
So my current i7-4790k can't use DDR4. So what? Excuse me while I fail to shed a tear for my dead and unplayable system.

shed tears when the mainboard dies and you have to pay premium for the replacement board, sold second hand and at premium price

ddr3 is not exactly dead yet, but is not the future, definitively

don't shed tears for intel, nor for amd either

shed tears for the cost of the platform you chose and when you want to move on and can't afford the migration

other than that, accept your reality and wait for the best deal

5 years on the same socket, you make it sound like a bad thing, your platform is at least 4 years old now, what are you saying? shed tears there

OK...and?
Anyone who bought an AMD system 6 moths ago or earlier, and wishes to upgrade to the new shiny...also has to buy everything new.
Motherboard, ram, CPU.

I'm not seeing your point here.

my point is not buy intel just yet, wait for prices to settle accordingly to the new reality, not their distorted reality where a cpu can cost 2000 dollars, no matter how good a cpu is, that is the price for a server part, and they surely are taking the 18 cores from bad parts from their xeon lineup that they didn't knew what to do with

about the 6 months, i advised most people to wait for ryzen, for price changes and possibly for a good ryzen platform, so far it has been a good advise, same as for now

anyway, the x299 platform looks very weak, as said before, time will tell, but doesn't look good for intel ultraexpensive platform, i would choose a expensive threadripper instead

And anyone that buys a $2,000 CPU right outta the gate needs a serious dopeslap, no matter which platform.

1300 is not cheap either, perhaps the rumor of 850 for ryzen makes a bit more sense

i would shed a tear when this thing becomes the best platform and i can't afford it

well, anyway, why do i bother? my current platform cost me 450 dollars and i barely could afford it!

the i9 samples have been delivered and monday and tuesday we will see real numbers, that might still apply the new platform, full of problems logic

but some leaks point ot a just a bit better than the old x99 best cpu, for more price than the old x99, added to the terrifying cost of the mainboar,d which i'm sure will not cost less than 400 dollars and it seems that you might need a psu with two 8 pin eatx 12v connectors, i hope i'm wrong on the last part!

people are still trying to understand what they did with that platform, intel itself seems to know the same as the users, nothing

from the epyc leaks for amd server platform, everything points to a 16 cores 32 threads cpu at around 900 dollars

the problem with that x399 is that mainboards will be expensive too, but at least the cpu doesn't cost double or triple the mainboard, that one afik, does need the new psu with two 8 pin 12v eat connectors for cpu :/
