You know, I do think we have to kind of scale back the insults. Yeah, this is kind of a weird thing to say that was maybe misinterpreted, but there's no way I would even stick around to explain myself (if I were him) given the way some of you talk. Please step back a little.
To be fair, looking at how he trolls nintendo fans in his own videos and how common these kind of statements are, it's pretty safe to say he thrives on this type of attention
I'll be good though.
The issue is not that the RAM is slower. It's that the medium with which the RAM is filled is the slow part.
Let's say the Blu-Ray drive in the PS4 is 4x as fast as the PS3 one but games require 6x as the amount of memory, then it's going to take longer to fill the RAM.
Streaming engines will just have stuff loading in the background. But if you just did a naive "fill it up to the brink" program, it would take longer.
There is such a thing as streaming from the HDD and installing games. And more importantly more ram means you don't have to flush the contents nearly as often ,so loading times should be significantly reduced overall.
Pc games have had negligable loading times compared to their consoles counterparts (order of magnitude shorter for 99 percent of games) since as long as I've known.
When people (well I at least) complain about console loading times it isn't about a 30sec preloading at the start of the game, it's having to look at that long loading bar again every time you go back to the menu, every time you restart a race, every time you reload a map or change maps , every time you enter or leave a house in skyrim etc etc.
On pc you are reading from the (way faster) HDD and all that plentyful system ram is used as a super fast buffer , so when your gpu needs new data most of it doesn't come from the HDD, let alone the disc.
Assuming MS and the devs who make games for the console aren't retarded they will use plenty of that 8GB of ram for caching as much data as possible (you can stream it in from the disc and HDD at the same time in advance or while playing or while in the menu) so you don't have to deal with many loading times, and as for PS4 I assume it'll be the same thing.
It should be even more seamless as it doesn't even have to be moved to the vram anymore since the unified ram is shared by the gpu and cpu already.
