Sony announced its new PlayStation 4 Pro console earlier this month, but since the unveiling event Sony has added 1GB of RAM to the PS4 Pro.
During an interview with Lead System Architect Mark Cerny and IGN, it was revealed that Sony has added 1GB of DRAM into the PS4 Pro, with the 1GB of DRAM being much slower than the 8GB GDDR5 RAM in the normal PS4. He said: "We felt games needed a little more memory, about 10 percent more, so we added about 1GB of slow, conventional DRAM to the console".
The additional RAM will also be used to store background applications for multi-tasking in your games, instead of reserving some of the unified GDDR5 RAM that it used for the OS and games. The new PS4 Pro will cost $400 and launch on November 10 with a 1TB HDD and remember, no 4K Blu-ray player. For that, you'd have to buy Sony's competitor in the Xbox One S.
