Anthony: Pay more for more cores

would be cool to see a video about historical CPUs where you could enable functional-but-disabled cores, and how they were diabled and why.

Ah I remember Phantom x3 with most having functional 4th core and everyone enabling them

My Ryzen 1600 actually has 8 cores. AMD leaves those cores on if they are good enough. It probably was a 1700 or 1700X but didnt meet the specs so they sold it as a 1600. It even shows up as a 1600 but... with 8 cores.

Brings back the memories of my 960T that was stable with the 2 other cores unlocked. It served me well for a good while.

Back in the day you could get a Phenom II X2 and there was a pretty good chance you could unlock it to a 3-4 core CPU with the right mobo. Though sometimes you'd be have to clock those cores lower or they just wouldn't have the same OC headroom, but it was free cores for a fraction of the price!

Ah yes. Who remember fun times when you could unlock fourth core in Phenom II X3?

ahhhh the good ole days.

I remember my old 6800GS video card having 2 pipelines disabled. You could just launch RivaTuner, feed the GPU a little more power, unlock the pipelines, and suddenly you had 6800GT performance.

Shout out to the dual core Phenom II 555 Black Edition that could be unlocked to a quad core that showed up as a B55. You'd win the lottery if it was stable upon unlocking, but when you pushed your luck with overclocking you'd discover how engineers are smarter than you and disabled those cores for a reason, hahaha. That was my story before miraculously being approved for a warranty exchange, the replacement being so bad that it'd almost immediately crash when I tried unlocking cores.

I remember in the late 00s/early 10s there were Athlon/Phenom CPUs that came with unlockable cores. 3-core CPUs were popular at the time, with 1 disabled core. Also 4 core processors with 2 disabled cores which were just Phenom II X6 that didn't pass QA. Usually these chips overclocked poorly but they worked fine unlocked!

I had an Athlon II X2 unlocked to a Phenom II x4 in my days, loved the darn thing.

I actually have 8 limbs - but shortly after production, intel cut off 4 arms. I am now considered a regular human.

I remember when the Radeon 9800 SE had its faulty pipelines disabled via drivers, so a custom driver could re-enable them. If you dropped the clock a bit, you could game with much more performance with minimal artifacts.

That's what I call a big brain move of making a good use of defective cores and saving a big buck by selling them as lower tier CPUs.

intel: manufactures core i9 12900k

Seems like an awesome “do not try this at home” followup where you guys try to enable the extra cores via microcode edits!

"Wasteful" is such a polite way to put it, when you think about how much water cost is involved.

There was a software for Intel CPUs back around 7th gen that got leaked. It was able to completely alter the microcode on the CPU. People found out that Intel had a bunch of lower tier CPUs that were technically the higher tiers with disabled cores. It led to a bunch of not so stable higher tier CPUs being sold on places like aliexpress.

I found on web some article that 1usmus somehow get readings of frequency from disabled ccx on some ryzen cpu, sadly the frequency was only at 500mhz if i remember correctly.
