It’s no surprise that Apple plans to refresh its line of iMac computers at this time of year and as Intel Broadwell is not available in the U-series version that can adapt to the iMac format, the refreshed models will receive processors of Haswell refreshment.

It’s not a huge leap up from current Haswell processors, but the 27in iMac will get a 5120×2880 5K display and new AMD graphics.

Current generation 27-inch iMac computers start at $ 1,790 and feature a 3.2 GHz quad-core Intel Core i5 processor. Nvidia GeForce GT 755M with 1 GB or 2 GB of video memory offers the pleasure of the eyes. The more expensive iMac references currently feature GeForce GTX 780M 4GB GDDR5 graphics.

With a 5120 x 2880 5K display, you need to render 14,745,600 pixels, which is significantly more than 8294,400 pixels on a 3840 x 2160 UHD panel and you need faster graphics. The GeForce GT 755M based on Nvidia’s Kepler architecture did a good job for the current gen and 2560×1440 panels, but it would be replaced by AMD graphics.

The new iMac 5K is expected to come with a Core i7 4790K Haswell refresh with a Turbo clock at 4 GHz and you can bet Intel is working on a Broadwell / Skylake version for 2015 as these processors consume less power and perform better. fast at the same time.

Important design victory for AMD

The 21-inch models will apparently stay with 1920×1080 panels and they currently use Intel HD 5000, Iris Pro, or Geforce GT 750M graphics. We’re wondering if we’ll see a GPU change in 21-inch Macs as well.

The 27-inch 5K design victory will be significant for AMD as the company has gotten a lot of positive coverage from its Mac Pro design victory and apparently there will be more AMD graphics in Apple products beyond the segment. professional.

The new 27-inch iMacs are expected this fall under OSX Yosemite.
