Today, Apple updated its iMac lineup with 9th generation Intel processors and AMD Vega graphics. The 21.5 inch iMac now sports up to 6 cores, while the 27 inch iMac gets what's presumably a fully enabled 8-core Coffee Lake die. Apple also says they're they're offering "Radeon Pro Vega graphics" in both the 21.5-inch and 27-inch iMacs. The subtext reveals that the smaller iMac has an optional "Vega 20" graphics card, while the larger one features the long-rumored Radeon Pro Vega 48. It's not clear if we'll ever see desktop gaming versions of these Vega GPUs, but some people have already pointed out that smaller Vega GPUs could cut into sales for the recently-launched RX 590.
