Yes, that is the question. It is pretty binary actually*, if it has similar frequency to the 7700K, it will use more power. Or if it uses the same power, it will have lower frequency.

I'm actually more interested in how the non-HT i5s fare power-wise. Especially vs. 4 core i7s.

*pun was intended...
I fully expect more power to be used, in fact, OCed power use might prove shockingly high, which may be a partial explanation for purported socket revisions.

A 6C/6T i5 ought to be able to smack down a 4C/8T i7, one would think. A pretty disruptive prospect, really.

Easily. At best Intel HT gives a 25% boost only in very selective workloads, making 4C i7 multi-threaded performance about 5 times it's single threaded performance. In those same workloads a 6C/6T i5 should deliver about 6 times it's single thread performance.

Which is why I am thinking the 6C i5, will in many ways be the best bang/buck, and what I will most likely get. Though I am unhappy that it looks like Intel cut the cache down on the 6C i5, to handicap it more.

If my 2500K system blows out I'd still be looking for a quad core. It is frustrating that they don't offer smaller core count processors with high stock/turbo frequencies.

I'm torn between buying a heavily discounted 7700K, a well priced racing grade 8600K or even 8700K, or a second system from the competition. My mind says 7700K is what is logical considering my current component inventory & needs, my heart wants that 8700K and my wallet will definitely accept the last option.

Oh... the sweet life of the spoiled consumer... where have you been all these years!?

Intel processors don't really go on sale much though. Even going back to Sandy bridge, new processors are still only ~$30 cheaper than they were at launch. Amazon is selling the 2700K for $299 (3rd party new) for example.

Maybe you were considering used processors though. Then you might find a good deal.

I am definitely going for i7-8700K. Got a nice opportunity to sell an I5-6600K at 4.4GHz at default voltage.

This CPU is going to be the next 2600K!

Has there ever been a 50% increase in core count since Sandy Bridge? Was an i5 from the new gen ever faster than the i7 from the previous gen? I'm not saying there will definitely be a sale, if KBL prices hold I'll move on to my next options.

My 6600K is not going anywhere, if need be it will power my first custom NAS machine. And when it's done and dusted it will join my Athlon 64 and C2D in the memory drawer. Excellent CPU.

But history can no longer be a sure guide, since the upcoming product stack changes are unprecedented.

Edit: @coercitiv , beat me to it!

No, there has not. But there have been equivalent performance increases. The 7700K is very roughly 50% faster than the 2700K but the 2700K price didn't fall.

The 7700K would go on sale if the general public who was making the purchasing decisions actually knew what they were buying. For the general public, I suspect that the vast majority would not know the difference between the 7700K and 8700K. Not any more than they knew the difference between the 7700K and the 6700K. For companies and institutions buying in bulk, those are generally on a schedule and that won't really change just because a new processor came out.

I honestly think non-enthusiasts are buying on price not performance. In that case, a change in performance does not necessarily mean a drop in price. If I recall correctly (it has been a decade so I may be wrong), the dual core Pentium D didn't cause the Pentium to plunge in price. Neither did the Core 2 Quad make the Core 2 Duo plunge either. Slight drops, yes. But major change? Not that I recall. I am a value buyer and bought the Core 2 Quad since the price was about the same.

Over the years companies like intel have gotten much better at managing stock levels, and will choose too little stock over too much stock. So they have no warehouses full of old chips that they need to dump cheap.

The supply they have will mostly go to fulfill long-term contracts like Dell business systems where they maintain an outdated configuration to simplify "fleet" management at major corporations.

Your examples are 5 generations apart, hardly a representative analogy.

So, since the 8700K is one generation from the 7700K, you know exactly what is going to happen? If so, please tell us.

I gave 3 analogies (change from 1 core to 2, 2 cores to 4, and 4 cores to we think 6). None are perfect. But, I highly doubt the Kaby Lake processors will plummet in price. Gradual and small drop? Sure. Plummet? Highly unlikely. Heck, in the last few weeks Amazon RAISED the 7700k price from $307 to $335.

My lack of prescience can't improve your analogies.

As my CPU is still more than enough for me, it doesn't matter how good any new CPU is currently, until software arrives that I want to use and my CPU can't adequately run it.

Then I will upgrade.

Your poll options could be better.

I agree with that, right now my 4770k is doing everything i want fast, gaming included. I will only upgrade if, at 1440P on a gtx 1070 i see an increase of 25-30% in FPS.

That got me wondering: i7 860 > 2600k > 3xxxk > 4770K > 5xxxk > 6700k > 7700k > 8700k. So 6 generations from 2600K to 8600k. But how do we handle 870, 875k, 2700k, 4790k? Were these generations? Stopgap fillers? Or what? I remember the 875k was a departure, introducing multiplier overclocking. The 8700k will be a departure, introducing 6 cores. What are we to think?

Interesting poll data so far. I don't think the real world will reflect the results. I expect CFL to sell like hot cakes.

In other words the beat goes on for Intel.

I am not really surprised at all by the poll. A certain % of posters would never buy intel regardless, and another % have recently upgraded already (either HEDT or Ryzen), or are satisfied with 4 cores. So 40% seems like a fairly good percentage to me. As for the general market, I dont think any new cpu is going to "sell like hotcakes", the market is just too mature. What will happen is that the mainstream buyer, when he finally decides to upgrade, will get more for his money and not even know it.
