Saat PS4 PRO terungkap , mereka menyebutkan mepertahankan konfigurasi PS4 asli dengan 8 GB GDDR5 dengan bandwith yang lebih besar. Tapi itu tidak sepenuhnya benar, seperti yang diungkapkan oleh Sistem Arsitek Mark Cerny pada wawancara eurogamer.
PS4 pro tetap menggunakan 8 GB GDDR5 tapi dengan tambahan 1 GB RAM DDR3 yang membuatnya semakin nyaman memainkan game.
WAWANCARA CERNY DENGAN EUROGAMER :
“We felt games needed a little more memory – about 10 per cent more – so we added a gigabyte of slow, conventional DRAM to the console […] On a standard model, if you’re switching between an application, such as Netflix, and a game, Netflix is still in system memory even when you’re playing the game. We use that architecture because it allows for a very quick swap between applications. Nothing needs to be loaded, it’s already in memory.”
“On PS4 Pro, we do things differently, when you stop using Netflix, we move it to the slow, conventional gigabyte of DRAM. Using that strategy frees up almost one gigabyte of the eight gigabytes of GDDR5. We use 512MB of that freed up space for games, which is to say that games can use 5.5GB instead of the five and we use most of the rest to make the PS4 Pro interface – meaning what you see when you hit the PS button – at 4K rather than the 1080p it is today.”
cerny juga menjelaskan bahwa developer dapat menggunakan RAM tambahan jika mau.
bukan perubahan yang besar tapi berguna PS4 PRO......
