It's more complex than it seems. Initially, each chip is crafted with the goal of forming the biggest possible unit containing all cores for use. However, the manufacturing isn't flawless, resulting in some cores being defective or unusable. This stems mainly from issues with silicon quality, which can arise due to various factors. The process isn’t flawless, so you should anticipate defects appearing. You can’t simply add or remove cores; each chip contains them according to its specific design. Binning decides whether certain cores are disabled or excluded. After testing, the chip is removed from the wafer and categorized. Based on yield results, adjustments are made to repurpose usable parts instead of discarding them entirely. This approach helps recover value rather than wasting resources, turning potential losses into profit.
I'm confused about what Throttlestop displays. My older laptop has an i5 4210U with only two active cores, not eight. It seems there might be a misunderstanding about the processor specifications. I need clarification on whether these are real cores or something else. Also, how can it detect cores that aren't being used?
It seems the processor likely has disabled faulty cores. You can't bring them back now. Back then it was possible but carried significant risk.
When the chip was produced, it was designed as an 8-core unit, but issues emerged after cutting and lithography. It was classified as unsuitable for its intended purpose, so defective cores were removed to produce a stable product. Throttlestop might identify these disabled cores using their unique ID, understanding the architecture came from a chip originally meant for an 8-core build. Due to manufacturing flaws, it didn’t qualify for the full 8-core design. This process was specific to AMD Socket AM3 chips only. Not every board or AM3 chip with hidden cores would unlock them, and some were simply too defective to function properly. I still own a few that work, though a few have limited core unlocking or incomplete functionality.
I noticed the actual chip inside my laptop by looking at it open. It’s still quite compact. How does it fit eight cores plus an integrated GPU?
Beerzerker, Intel CPUs can reach up to 24 hybrid cores, but not every chip has exactly that number. Some may have fewer functional cores compared to the total. It seems there are processors designed with the correct core count but with some disabled. I noticed someone adjusting voltage on a 12700H and it reported only 14 cores, while throttling stopped showed 8. There’s clearly some confusion here.
The lithography enables the creation of such tiny components. When talking about a chip measuring 7nm or 10nm, it describes the resolution of the process being applied. At these diminutive scales, precision becomes extremely challenging—making execution difficult, even harder, and significantly more prone to errors. Here are some references that can clarify the concept and its importance.

The parts are really tiny. Yes, it could have been an i7, but they had broken parts and it never turned into that. So it ended up as an i5.
Small can mean different things depending on context, and your perception might not match the true dimensions. It could actually be the intended size.
