content: I would never ever have expected somebody will fake a high-end CPU.. So much effort worth of $300..

content: Technically, it is not that much effort. You can realistically prepare all the manufacturing files in a couple days. If would be a fun video for someone to order all the parts from JlcPcb or PcbWay. They should have no issues making everything. You may need to glue the parts together and may be laser etch. Thankfully laser etching companies recently seeded a ton of youtubers with equipment. It would also be interesting to see if those companies will possibly refuse to make the parts.I'd say the most challenging part is figuring out the distribution network. But I guess there are crooks out there that know how to distribute this fake stuff.

content: Fake CPU's have been a thing for quite a long time. Even back in the 1990's, you could get re-labelled Pentium CPUs.https://www.cpu-galaxy.at/article/fakes.htm

content: But there's nothing in it. It's completely nothing. How are they managing to sell any kind of volume?I guess it's just a one-time thing, they sell as many as they can within a couple days probably, then disappear and will have made a few tens of thousands bucks along the way.

content: What a completely ridiculous thing to do!If you just bought $179 RRP 7500F and relabelled them and sold for $300 you'd make a less money on each one, but 1) for a lot less expense, and 2) many people would never notice anything wrong.

content: I commented this on the video but I thought i would also put it here.Looking at this I think it's a possible display model , quite often when they are releasing a new chip they dont want the actual silicon floating around just yet so they have exact fakes made up for photo's, conventions where they need as close to release model as possible without the chance of someone stealing them.Intel also did this, back in 1992, I was at Birmingham NEC for a computer show and they had all these Pentium cpu's on display but only one real chip which was in the display PC, being a excited 12yr/old i got the Intel engineer to show me the actual chip and the explain the fakes He told me that the pc would be going back to his room so not to get any ideas. That same evening thieves broke in and stole the fake display chips and mobo's (also fake) which also were marked 586 and not pentuim at the time,I think PC World ran a article on it too but failed to point out these were display only and had no value after the show.darkspr1te

The cost was for the default unfinished aluminum.Changing to bead blasted steel and adding laser engraving increases the cost to ~$22.
