Let me guess. It's better in popular (read DX11) games. Worse in everything else (compared to R7) and more expensive than Ryzen. But because of kids looking for GTA V Benchmarks find it does 2FPS more than Ryzen it will still sell by the millions.

Whats my prize?

Not necessarily. It's a lot different this time with AMD back in the game. While I love Intel they won't do as well as they have done. People are tired of the Intel monopoly. Nice to see competition

Agree. That wasn't written by engineers. It was written by a marketing team who were told to come up with something to combat the thermal paste hate.

it was written by der8auer at least his name is attributed at the top of the article. It's not me that's trying to justify it I was just merely presenting it for people to take into consideration as I found it rather interesting.

Make your own minds up about it I've already stated I think it's more of a financial decision rather than it being of a technological nature.

That really isn't a summary of why they're doing it at all, it just reads like a justification of it. If you think Intel are doing it because mining gold is polluting you're just not living on this planet.

Sorry to cause confusion but I already gave my opinion hopefully still based on this planet

Do we know how the Intel Coffee Lakes compare to Ryzen yet?

Thanks

Wont these just be equal to the Skylake-X cpus? No IPC change, same clockspeed etc. Maybe the i5 will lag behind with no hyperthreading?

Due to the cache layout and lack of MESH interconnect the Coffeelake CPUs should perform better for games than the Skylake-X equivalents.

Why would they release coffeelake that's worse the 7700k. 8700k should be faster.

Guys I wrote on the other discussion my theory of this last night.

The common denominator all the reviews is the usage of NVidia gpu. We know since April that there is issue with the NV drivers and Ryzen topology.
Also the Intel spec sheet for optimizations of X299 CPUs and their new topology is similar to the optimizations required by Ryzen CPUs, it seems.

That explains the whole performance results of the Ryzen and X299 CPUs compared to the 7700K is down to NVidia drivers not the CPUs.

I bet when the Vega reviews start hitting and if any reviewers bother to test the various CPUs with it, we might find out that the KabylakeX/SkylakeX and Ryzen perform as they should not like cripples. Unfortunately asking them to run the benchmarks with FuryX or Rx 580 might make the 7700K crowd unhappy talking about GPU limitations.

Imho if anyone knows any AMD or Intel rep, (@AMDMatt) should raise the issue for investigation

I've not been following closely.. Has this been confirmed (i.e. lack of mesh)?

I don't believe the lack of mesh has been 100% confirmed, but may have missed that myself. The cache layout has been confirmed though, and it would make very little sense to pair the traditional cache hierarchy with mesh.

Any idea on if they will be compatible with Z170/270 motherboards yet?

Selfish mode on:

God I hope not, needing a new motherboard may actually mean there will be enough stock to buy one launch day, which won't be the case if all you Z270 peasants are able to jump on board with just a BIOS update...

Hahaha i hope they do both chipsets just for you!

Yep, Coffeelake is identical to Skylake, which is identical to Kabylake, and so no. 0% IPC increase, just more cores that will go unused in gaming.

We don't know this yet.

Yes we do... Skylake, Kabylake and Coffeelake are the same architecture, meaning 0% IPC increase. Nothing to get excited about, since 6 core Skylake's are already available, performance will be within 1-2% of the Skylake models.

I hear Intel is doing 1151.v2

Some news sites have said that, whist others have said it uses a standard 1151. I've seen some reports claiming the CPUs will arrive before the new chipset. I don't think we know for sure at this point. Technically compatibilty should be possible, but Intel may have other commercial ideas.

Whilst I agree you're likely correct on Coffeelake matching mainstream Sky/Kabylake, the only 6 cores are Skylake-X (on the X299 platform) and these are actually quite different to the maintstream CPUs.

CoffeeLake is using the old ring topology. Not the Mesh one used on the KabylakeX & SkylakeX.

I suspect that it will have slightly better IPC,but since they are adding 50% extra cores on a slightly tweaked 14NM process,the CPUs probably won't as aggressive boost,as say a Core i7 7700K,hence the lower base clockspeeds. OTH,with 50% more threads MT performance should be better.
