Bloomberg published an article with rumors about Apple's upcoming hardware, which includes codenames that suggest Apple will be building a new chip with 10 big cores, 2 little cores, and 32 GPU cores. It will be used in either 1, 2 or 4 chiplet configurations across the Macbook Pro / Mac Pro lines, as well as higher end options for the models that replaced their low end SKU with the M1.

Obviously 40 big cores will totally blow the doors off the existing Mac Pro and every single (and perhaps even dual) socket Intel workstation, but how will 128 of Apple's GPU cores compare to AMD/Nvidia's current high end graphics cards? That's 8x more than the M1 has, how far behind the high end discrete cards is the M1?

I'd put my money on this new chip getting CPU/GPU cores from the A15 rather than the A14 like the M1, but I guess we'll see. It also possible Apple will use TSMC's HP process to make these, trading off some chip area and power efficiency for a higher clock rate.
