One AMD advantage is that it’s manufacturing basically a single part, not the large options of Intel. One part binned and combined into chiplet designs. 8 core to 64 core, its all the same part (1, 2, 4, or 8 of them). There is likely cost savings to this strategy as well.
I imagine they will do that on the GPU side as well at some point.
- selectodude 6y agoAMD's yields are going to be better too since it's not a monolithic core.
- doikor 6y agoAlso gives them a lot of flexibility with binning which should give them excellent yields. The ones that don't have full 8 (well enough) working cores just use them for 5600X (6 core) or 5900X (12 cores) if there is 6 or 7 good cores. The fully working chiplets you can bin for 5800X or 5950X (or for threadripper/Epyc for the very best ones)
- maximilianburke 6y agoAdditionally the I/O die on the Ryzen chiplets also gets reused as the X570 chipset, also I believe based on binning.
- bcrl 6y agoBonus: AMD satisfies their contract with Global Foundries by including one I/O die manufactured by GF with every CPU sold.
- fomine3 6y agoIntel also uses chip with defected cores for lower core SKUs.
- doikor 6y agoYes but Intel can't take 2 (or 4 or 8 or whatever number you want) of defective parts and sell it as a high end part. AMD can make a 5900X or a Threadripper/Epyc out of 6 core chiplets "defective". As Intel chips are one big monolithic designs they can't make a 6 core consumer desktop CPU out of a broken 24 or 28 core Xenon chip.
