The only reason behind silly socket changes like no tomorrow by Intel is their own greediness.

That's true for people that would buy a new cpu and plug it into an old board. For people like me.... the board makers are going to pop out a bunch of new motherboards (even if the same chipset and/or socket) with all these things my old board doesn't have. Then I'm going to buy a "new" board anyway.

I had my 1700 on 5 or 6 different x370 boards before I sold them all to wait for a TR build. Even if I kept my 1700 until "Zen 2" I would most likely buy a new board even if it was fully compatible with which ever one I had by then.

Now I managed to only buy two Z270 boards, but I had a closet full of Z170 boards. I also managed to only buy one X299 board... and I think only two X99 boards, but to be fair one blew up.

but um anyway... Obviously I have a motherboard issue, so I guess that the buying a "new board" thing doesn't bother me as much.

nope, they've been updating DMI lanes and adding DDR4 support, you can't support either without switching sockets since they're not pin-compatible.

Sorry to tell you, but if you had a closet of Z170 boards you paid for all, you're simply a consumerism victim.

That doesn't apply to each gen, and of course, bar DDR4 support, DMI lane updates could've been 100% pin-compatible in most cases.

no they don't, DMI being upgraded means old gen CPUs won't run with new chipsets.
simply put, DMI is only backwards compatible, it doesn't run the other way around.

with that in mind, why would you then make the new chipset reuse the same socket and end up having a ton of RMA from having the wrong CPU placed?
change the socket along with the new chipset, not only would it prevent issues from going around, it'll also guarantee that the newer CPUs will be running at their full capability.

A closet full of Z170 boards cost a lot less than my car modding hobby and they depreciate far less when "recycled".

I'm not sure how victim enters the picture here... Consumer driven markets where companies exist to make profit. Kind of depend on consumers buying products... You choose whether you want to buy them or not.

when i upgrade rigs, i keep the old CPU+mobo pair in another system,swapping just the CPU alone means the old one is sitting there collecting dust.
with this approach i have two running rigs that can readily be accessed, furthermore in my area its easier to sell the entire rig than selling it part by part.
better yet, i have my old rig ready to substitute whenever i encounter issues with my new rig.


on the other hand, at the rate i upgrade my rigs i always end up with an ancient rig, with the new stuff having lots of new features it simply makes keeping the old board pointless.
take my previous rig for example, it only had SATAII, 100mbps NIC and USB 2.0, this current rig in comparison has all of the better goods plus more.

I'll likely be getting a i7-8700k or i5-8600K as long as the pricing isn't ridiculous.

4.7GHz single core boost with 4.3GHz 6 core turbo is leading to believe that they will have little headroom for overclocking the i7.

The i7 premium likely isn't worth it for most people that OC, seeing how use of over 6 threads requires massive amounts of parallel code. HT only gives +30-40% performance.

the base and turbo clock is high enough for the lock chips to be attractive for most.
imho overclocking a 6core is a serious matter, heat alone wouldn't be cooled by some cheapo aircooler.

Actually, no.
The DMI changes rarely have to do with CPU socket pins ( have you ever counted how many pins are NC ? ).
Sometimes the DMI changes were between the chipset and sata controllers and other host controllers, not directly to the CPU.

Most of the times those changes could've been easily made pin compatible, way more complex things are pin compatible in high tech than simple interconnects and master clock BUS controllers.

And like I said, not between all generations DMI changes occurred.

You may not want to face it, but Intel has been juicing us for a whole lot of time.
You seem to be "used to it", I've been on the ride willingly, but I do not condone such tactics.

Anyway, from an engineering point of view ( that's what I studied and do for a living ) most of them could've been done single socket compliant.
