Intel: "What’s amazing is that trade-off, this actually being a 5GHz in single-threaded performance frequency and not...having to sacrifice that for this kind of multi-threaded performance, so you've got kind of the best of both worlds. So, you guys want to see us productize that thing? Tell you what, we'll bring that product to market in Q4 this year, and you'll be able to get it."
I think claiming that's a flat out "lie" is a little overreacting. Did that imply that this chip can run at 5GHz reference stock speed on a single core? Yes it does because they did not mention it was supercooled overclocked. However, he did say "this chip" and not "this 5GHz single core speed" chip. Let's also keep in mind here this chip is not even released yet. If they make that claim on the box and in ads at release time and it is not true, then it is a flat out lie to the consumer. Besides, who would buy this and run it on a single core anyway? Those days died out long ago.
In any event, I think the correct word here is "misleading" or "deceptive" and not a flat out lie because as stated you can't buy it yet. And as this article mentions, all companies do that in future promises (then they change the specs at release time). It's up to you, the consumer, to do your complete homework in whatever product or service you buy. Most people never even read the fine print on their auto insurance or credit card documents.
Anyway the parsing of words here is really not the most important issue for Intel on something we can't even buy one way or the other. I'm most disappointed in Intel's more recent fails at thermal management designs and going cheap on adhesive/paste applications. Especially as Tom's proved here with their excellent i9 de-lidding and overclocking article. The fact that's a near-$1,000 chip and it has to be de-lidded to get better overclocking performance is just pathetic. Especially when looking back at Intel's history of being excellent overclockers. No matter what however, history will show that AMD put Intel in a scramble when they released Ryzen and severely caught them off guard.
