Intel’s next CPU cores (Broadwell) are significantly delayed, so
in the meantime, they released a few more high-end Haswell models.
The Retina iMac’s 4 GHz option is the Core i7-4790K, which is
currently the fastest CPU in the world for most single-threaded
Since the Xeons in the Mac Pro are based on the even older Ivy
Bridge microarchitecture, they’ve been lagging behind even the
previous iMacs for single-threaded apps. According to early
Geekbench reports, the 4 GHz, 4-core Retina iMac appears to be
25% faster than the 6-core Mac Pro in single-threaded tasks and
only about 15% slower in multi-threaded tasks. That’s incredible.
I ordered one yesterday. Jaw-droppingly gorgeous display, outstanding performance, and amazing technology to make it all work. They could have gone “retina” with scaling earlier, but instead, Apple waited until they could truly go pixel-for-pixel @2× retina at 27 inches. I’ve never bought a new machine with less hesitation.
As for price, keep in mind that 10 years ago, the original 30-inch Cinema Display (resolution: 2560 × 1600 pixels) cost $3300. Just the display.
