If AMD offer an unlocked 8 core chip with Sandbridge performance I'd be all over it quick smart.

Unless it was sub-£250 that would be a pretty niche choice.

At a more realistic price of £350-400, the vast majority of the time you'd be better off with a 6-core i7 6800k. Since most things don't use 8 cores still, and the 6800k would have ~25% higher IPC.
 
I'd probably pay a little more for the move to AM4. No more choosing between Z170 and X99.

The 6800k isn't going to be 25% faster than a 8 core sandybridge.

It will be in anything which fully utilises the CPU up to 6 cores.

Intel have made very slow progress per architecture change. But since there's been a good few now, they all add up.

Sandybridge -> Broadwell or Skylake is a decent upgrade.

For that to be the case the 6800K will be the biggest performance jump Intel have made for the last 10 years. Intel themselves said performance per core would drop.

We already know how fast Broadwell is. The laptop and mainstream desktop chips tell us that. And it is ~25% higher IPC than Sandybridge.

Intel were talking about future architectures when they said that (as in several years out). Broadwell-e will be faster than Haswell-e (not by much, but a few % per clock).

Likely Intel mean their 10nm, or maybe 7nm, chips will start being lower IPC in favour of efficiency.

Most of Intels gains come from the 400-500Mhz clock speed they added to chips over the years. We've seen a few percent between each chip since sandybridge.

If AMD match Sandy-Ivybridge they also match Skylake and Kabylake. If AMD beat Skylake by a few percent than good on AMD, but no one will care because the performance between all the chips will be tiny.

Broadwell is a z170 chip. We've know how fast Broadwell has been for ages. It was released last year. And guess what it's arguably slower than Haswell.

None of this is true at all.

I said IPC because I meant IPC, not the 400-500 MHz clock increase.

Broadwell is faster than Haswell hands down. It's a small increase but it's there.

I don't know what benchmarks you've been looking at, but this is just plain wrong.

Whatever fella.

All AMD have to do is match Intel's second round of core i chips. That puts AMD back in the game. Anything faster is all gravy.

Broadwell is not a 'Z170' chip! Please check facts before posting nonsense. Broadwell ipc is superior to haswell... As well so pretty much the whole post is wrong
 
Zen 8c is likely to be <150mm sq, there is little point making 2 or 4c version dies. Any 6c version will be salvaged parts unless the yield is so spectacular they disable cores... Hopefully not with a laser. Remember Phenom/Athlon unlocking? :D If it's terribad, there may even be 4c versions at some point
 
Hope AMD phase out dual cores and have quad cores as their entry level desktop chips. Can't believe it's 2016 and Intel still charge £100+ for a dual core.
 
I did. Proud owner of an overclocked 860K. The money I saved over the Intel system went on a better graphics card and more memory.
