"xx" is pretty often used as family, not as product. Otherwise how one product CN92XX can come with 12-18 cores *in the same time*? https://www.marvell.com/company/newsroom/marvell-announces-octeon-tx2-family-of-multi-core-infrastructure-processors.html "Marvell’s CN91xx, CN92xx, CN96xx, and CN98xx processor families include:" https://www.marvell.com/products/data-processing-units.html > And CNF95xx is another silicon variant in the same family. > https://www.marvell.com/content/dam/marvell/en/public-collateral/embedded-processors/marvell-infrastructure-processors-octeon-fusion-cnf95xx-product-brief.pdf Again, unspecific product brief.

Are they? "Up to 8" cores, so how this can be one specific silicon? One customer buys CN10300 with 8 cores, second buys exactly the same CN10300 and has 4 cores? You are mixing families and specific devices. Best regards, Krzysztof
