Yes i can, because it's true. The difference is in the process like i said. Coffeelake is just 2 cores added on to the 4 existing Kabylake cores, i don't consider that a spectacular engineering achievement at all. It's and engineering effort yes, but certainly not spectacular achievement. If it was a 50% IPC improvement, that would be spectacular. Adding 50% more cores doesn't translate into 50% more processing capability.
The TDP doesn't align with the power draw of the chip, that is special condition number that intel seems to have tagged on for marketing purposes. Is it 50% more power for 50% more cores? No it isn't, because the process improved.
This is a pivotal moment in the industry. In some respects, intel has now lost that process lead. A physics wall is fast approaching and any remaining lead is going to diminish to nearly nothing. This is where the rubber is going to meet the road and who has the best architecture for scalability. I think intel has unfortunately relied too long on it's process for it's dominance in the industry and forward thinking on design has taken a back seat.
To the poster that claimed Coffeelake wasn't a paper launch, it is the exact definition of one, not sure how you can say otherwise. This is a trickle of product to the market in ultra low volume.
I can say this no company on earth including Intel, Apple or AMD can improve IPC by 50% on their existing high performance CPU core. Getting 10% improvement is considered very good. Apple manages to get 20% IPC growth with a very tight integration of CPU chip design,OS and first party apps which make good use of any of the architectural improvements and/or ISA extensions.
Yes, so what it boils down to is a 10% IPC lead, which subsequent versions of Zen should eliminate, and a process that clocks higher. So at clock parity, the 8700K would have a 10% lead in stricly single threaded applications (of which there are very few) and fall well short in performance for multi threaded applications compared to the uncut 8 core Ryzen chip at the same price point. As i said in the other post, yes it is an engineering effort but not spectacular. The process allows it to clock higher.
Neither Intel nor AMD is standing still. Both companies continue to make architectural improvements. Icelake will bring IPC improvements to Skylake as Zen 2 will bring to Zen. How much AMD is able to narrow the IPC gap or will the gap widen will be known when the products launch in 2019. As for process related clock speed advantage that is a key advantage for Intel . GF and AMD need to be able to compete on that front too if they want to compete on overall performance (ST and MT). The fact that the 8700k is competitive with 1800x for MT while crushing it on ST points to the significant gaps AMD has to cover both in IPC and clock speed.
