Apple’s UK store page for the base configuration (Apple M3 Ultra chip, 28-core CPU, 60-core GPU, 96GB memory, 1TB storage), as the Internet Archive saved it. Each row runs from the first to the last Internet Archive capture MacIQ read at that price; the price may have held before and after. A price changed some time between the last capture read at one price and the first read at the next, so no day is given. A “From” price is the store’s starting price for the chip option; the base configuration is the lowest one listed under it. Read 18 October 2026.
