Two years in a row the top GPU option for productive Mac machines are powered by AMD Radeon graphics.
Last year we saw the Mac Pro with AMD FirePro graphics cards inside and today Apple announced the new iMac 27-inch model with a Retina 5K display and an amazing 5120x2880 resolution powered by two high-end AMD graphics cards.
Apple says you will be able to choose between the AMD Radeon R9 M290X GPU or the faster AMD Radeon R9 M295X. These two mobile GPUs should be based on a Tonga GPU, but we this is not official yet.
Apple states that iMac Retina 5K has 7 times more pixels than 1920x1080 Full HD and in numbers this computer trapped in display has 14.7 million pixels. If this is not enough numbers, Apple reminds us that 5120x2880 resolution is 67 percent more pixels than the famous 4K.
5120x2880 display meets Radeon R9 M295X
The 27-inch iMac Retina 5K comes with a 3.5GHz quad-core Core i5 processor and it is available today for $2,499. There will be a more expensive model with an AMD Radeon R9 M295X graphics card and an Intel Core i7 CPU at 4.0GHz called CTO, but Apple did not mention the price of that one. Currently it seems that the basic model comes with a 3.5GHz Core i5 and a Radeon R9 M290X graphics card.
The AMD Radeon R9 M295X is capable of reaching 3.5 Teraflops while the previous model was stuck at 2.5 Teraflops computation power. The previous iMac 27 had a 2560x1440 display and two GPU options from Nvidia, the GeForce GTX 775M 2GB and the GeForce GTX 780M with 4GB of GDDR5 memory.
US $4399 for the faster spec machine
Apple also mentioned that the new 27-inch 5K Retina display iMac has a 1TB Fusion drive option.
If you order the Retina 5K model with the 4GHz Core i7 processor, 32GB RAM, 1TB SSD Fusion flash drive and AMD Radeon R9 M295X 4GB GDDR5, the system easily gets to US $4,399.00 and this is without any accessories or software.
