Wasn't there a rumour about Sony launching 2 Dev kits with 8 and 16GB ram quite recently? Doesn't that show flexibility and that they have yet to finalize specs?
I cannot vouch for the validity of VG247. However, I can echo the VGleaks page. I constantly am referring to this page here- http://www.vgleaks.com/world-exclusive-ps4-in-deep-first-specs/
That is your PS4 with 4 GB of RAM. Two different PMs have told me I am "very" close with the specs. One PM even asked me if I worked at Sony.
I agree. 2GB was a reasonable target, but they probably got a bit scared of MS going all out and losing their edge in graphics (despite of the fact that they don't really need to go all out to win a gen, as Nintendo has proven), so they decided to push out for 4GB, the dame way MS upgraded 360 to 512MB after Epic complained. Aside from that, any other major mods at this point would require extra time and a lot of money and they don't have neither.
To be quite honest, Sony doesn't NEED to either. 4 GB of GDDR5 is an incredible amount of hyper fast RAM. It will have some very specific and noticable advantages. Programmers should quit their job if they can't figure how to utilize 4 GB of GDDR5.
4GB is the target amount for final spec, not in devkits.
Correct sir. It's might not be GDDR5 either, its 4 GB of RAM with 192 GB/S speed. Which is at the lower end of GDDR5 speeds, but still fast enough.
