I have no problem at all with Intel's policies. They are a for profit business, not a romantic notion, just like AMD. Neither Intel nor AMD gives a flying screw about me, and I hold no illusions about either.
The idea of getting upset because a company doesn't do what you think they should, or liking a company because you think they do, baffles me.

All I basically care about is that the product does what is claimed at a price I can stand.

I couldn't have said it any better myself.

Intel also has some of the finest engineers that worked on it. We can be sure they have tested both tim and solder and that the end products meet their requirements.

Intel isn't out to get me or anyone else. They are in the money making business. And they're good at it, and have the products to back that up.

Well, RyZen seems to be running as fast as it can out of the box.
That's really the big disappointment there. Nice big contact area. Proper TIM. But really can't clock much higher than the stock, meant to last forever, clocks.

Well, it can . . . if you buy the "low end" chips like the 1700. Then you can get 1 GHz overclocks!

1800x? Not so much.

Yeah but the 1700 is down binned to hit the 65w TDP. But we know that the Zeppelin die just plain caps out only slightly above the highest stock clocks.

I would be grateful if someone could explain the AVX offset to me, how it works, and if you can disable it; I have no use for it and like the higher clocks.

It adds an offset to your clock frequency when the CPU encounters a 256-bit instruction. In some leaked BIOS screenshot I saw for Skylake-X, there is another offset for AVX-512. The offset exists, because you will not be able to run AVX code at the same frequency as non-AVX code. AVX code has increased power delivery and cooling requirements. Without AVX offset, you would have to limit your OC frequency even in applications that do not contain AVX instructions, so you should not "disable" the offset (although the default offset is 0).

Much appreciated! So because it's disabled by default I'll have to enable it to reach a higher OC and since I won't run into AVX situations that's that. The offset automatically determines the new frequency when it would run into AVX situations because it's an offset of my OC, I assume? In other words; I don't have to manually determine a 2nd, AVX OC frequency?

Are there different offset levels?

The offset applies a negative offset to the clock multiplier - so if you increase the multipler by 5 (thus increasing core clock by 500mhz), you can apply a negative offset of 5 to keep the AVX frequency stock.

Is there some reason for not using solder ? The chips are higher priced, why did they go cheap ? The HEDT chips are already notoriously hot once overclocked, even with solder. They use a lot of power when you overvolt and overclock them as well.

I'm not doing a delid on a $1000+ chip, not sure which one I'm going to get. Pretty sure not the 18c, likely the 10c. Anyone running these on air, or an AIO water cooler, and trying to overclock them may end up finding the temperatures are not manageable.

My current soldered chip with a really good water setup still gets temps in the 70s at times. Higher running a stress test, but for general use the temps already get high.

Honestly with an AIO water cooler, the temps on the Broadwell-E 10 core @ 4.3GHz were barely manageable when I had it, even though it was soldered.

Basically, when your CPU runs AVX code it fires up the AVX units. These can do a lot more work per cycle, but it comes at the cost of additional power. What the AVX offset does is it allows your CPU to, for non-AVX code (which is a lot of what you'll see in consumer workloads), run at a higher frequency than it does when running the more taxing AVX code.

It's a cool feature, I like it a lot on the 7700K.

I'll find out because I have an AIO and won't be doing custom water even if I have to keep all cores at 4.3 it's still overall better than my i5 at 4.6.

Enjoy! While I'm strongly considering SKX, I'm still very tempted by the idea of a hex core CFL on 14nm++ for its super high frequency potential.

If CFL is Z270 compatible, then that's a no brainer for me, but if the rumors that it'll require Z370 are true then...ugh.

Same here. I will be running a 7820x under a H115i. However, I will delid if we see big gains by doing so.

i9 is just a branding scheme to combat the Ryzen pressure. The i9's will just be the high end desktop parts that are Xeon's with ECC removed and repackaged. It is nothing different than prior high-end desktops which were labeled i7 with an X at the end. They do not have integrated graphics.

I was thinking of Kabylake X.
Me too - but I can't see the advantage - not using X299 features like Skylake X - disabled the Kaby Lake iGPU. I'm waiting for Coffee Lake 6 core with iGPU.

Except that Intel had the i9 name ready to go once before, but didn't pull the trigger. Using i9 was not a new idea at Intel.

I'm missing the point I'm afraid? They could have called them Hello Kitty's Pink Pleasure Island for all I care (but glad they didn't) we all know what they are and we all agree that what matters and is discussed here is performance, packaging etc.

Same here. I will be running a 7820x under a H115i. However, I will delid if we see big gains by doing so.

I'll be using my H105, which I picked because it has a beefier rad.

Thanks man!

I think they're probably true. Maybe because older boards can't handle more cores with their VRMs etc.?

The poll sits currently at 24 votes for yes. I wonder how many didn't vote, and how many in total will eventually end up buying SKL-X.

I don't agree, the reason people are angry is that Intel decided to save 1 USD per chip while they could have used solder for much lower temps when overclocking. A penny wise, pound foolish decision to me. Why cheapen out on something like that when your marketing is all about "extreme" and the best there is, etc. I don't get all these apologists.

I have to correct you here somewhat: people assume that it was a cost saving decision. Yet people simply don't know.

There is a good chance that at the packaging stage Intel doesn't even know if it's an "extreme" chip or not. Enthusiast SKUs only exist because it's trivial to relabel a regular SKU and overclock it.

6950X is soldered. Replacing the solder with good TIM lowered the temps by about 5 degrees. So in that case, solder was not any better than good TIM.

https://www.overclock3d.net/news/cp...elids_intel_s_core_i7-6950x_broadwell-e_cpu/1

I think the poor TIM used by Intel recently has people believing that solder would be a lot better.

No, it didn't. Reducing the space between the IHS and die is what reduced the temps. TIM, even "good TIM" won't have the same thermal conductivity of solder. The liquid metal stuff comes close but quite tricky, not to mention risky to apply correctly between the die and IHS.
