Earlier in the week, several tech tweeters and PC news sites reported on some interesting AMD Zen 4 processors spotted in the online Geekbench results browser.Unfortunately, we admit that the list of CPUs was forged chips and cheese, was revealed to be behind Thursday’s prank. The site explains that he, one of its creators, used a newly exposed tool called the tool to spoof AMD Zen 4 results. PMC ReaderAs expected, there have been several CPUs with comical names in the last few hours. I also had a CPU named Rickroll, but like I said, I screwed it up now…

Mr Astley’s CPU will never let you down
Chips and Cheese’s PMCReader article explains that on current AMD systems there are six CPUID strings held in registers that can be easily edited to misrepresent the product. A new tool makes it easy to edit your registration details (up to 48 characters). The registers are typically set at boot time, and tools such as Geekbench, CPU-Z, and AIDA64 check the registers to identify the CPU and report it in system information and benchmark results.
Another interesting aspect of this tool is its use in less conspicuous fakes. This happened earlier in the week as a result of the AMD Ryzen 7 7800X 10 Core CPU Geekbench. As long as the trickster has a processor with more CPU resources than it needs, it can be configured to “create” low-tier fake CPUs. Chips and Cheese says he faked 7800X results by tweaking AMD Ryzen 9 7950X. I changed his CPUID string for the processor, used the tuning tool to implement a negative 350 MHz PBO offset, and removed 3 cores per CCD. The site claims that this “fools most people”, and it certainly did.
Stepping away from PMCReader’s potentially sneaky usage and firmly back in the fun realm, techies are enjoying the PMCReader tool and the 48 characters they can edit to spoof their CPU name. Take a look at some of the screenshots circulating from yesterday in the gallery below – are these real or fake?!?!

With tools like PMCReader available for free, will the world of leaks get back to normal? Those looking for early insight should be doubly careful.
