Kam B, who needs luck? If you read up in the comments, it's already been pointed out the cost for Intel boards is way more expensive than AMD. For the 10'ish percent increase, do you feel 300 to 400 more bucks is a good tradeoff? Looks like you and Intel are the ones needing to hold onto that luck.

Всегда покупал Интел, но нынче купил АМД 5 серии. Горячее дерьмо мне не надо.

I'd buy the 5900x if it came down in price to equal the 12700k...which seems to outperform the 5900k...until then they can keep it...price gouging works BOTH ways.

It's not just about the CPU when it comes to Cost. Intel's Motherboards have always been a lot more expensive than AMD boards with similar features. So in some ways, the Cost equals out when buying a CPU and MB. I bounce back and forth between Intel and AMD so no fanboy here. These days they will constantly be leap-frogging each other since they don't release new CPU lines simultaneously. One positive thing about AMD is being able to use the same AM4 Motherboard and upgrade to newer CPUs while Intel likes to change their damn socket type a lot more frequently so for some people they would need a new Motherboard as well for an Intel CPU Upgrade. At the moment Intel is in the lead with PCI 5.0 and DDR5 but of course, AMD will be right behind them. There is a lot of Subjectivity for CPUs and what people's needs are but there is also a factual objective side about what CPU is better for the money. I'm a 3D Modeler, Animator, and Unreal 5 hobbyist/developer so for me, having those 24 to 36 cores is extremely valuable, worth paying more, and because it saves me a ton of time in rendering and workflow (like 1000+ hours with my current AMF setup compared to a 11700K. So saving all that time is well worth the cost, by far. But yeah, most people who argue over which is better are Gamers and don't see the value in what certain CPUs do for Productivity/Workstation uses.

Why on the 12700k's Intel Ark website it says that it's a 7 nm processor and not 10 nm someone pls explain.

they changed the name of their intel 10nm enhanced fin-fet node to "INTEL 7"

Intel just fooling consumers and creating confusion by naming their 10nm process to "Intel 7" it is just branding. There is no meaning of the number 7, it is just a plain 10nm process Intel trying to develop on their mobile cpus for 4 generations. There were 10nm processors on their 8th gen.

Emre, We really got some AMD Fanboys up in here I actually like AMD Graphics Cards more than Nvidia in my opinion, but Intel has the lead right now in performance and what's said is a 10 nm Processor beating a 7 nm processor, even by a tiny bit. To be honest, right now Intel got more Processors at a better value and performance than AMD anyways good Luck.
