View Full Version : A Question of RAM

Let's say that Microsoft had put more RAM into the 360s than the previous model, and from that point devs could program games to make use of that increased RAM as an option (while also making it work with the old configuration.)

Would simply having more RAM available make a significant difference to the 360's graphical capabilities? I'm thinking mainly about texture resolution and draw-distance since they would be the most practical things to upgrade on a single-disc, dual-version basis. Maybe they would also bother having, say, improved atmospheric effects or other things I can't pronounce.

This question came up a few times in conversation over the years but I wouldn't know if the RAM is a major bottleneck or if the hardware as it stands could not make worthwhile use of it without also upgrading other components. For example, I had a stubborn friend who was convince simply putting more RAM in his computer should make a big difference with games graphics but he had no dedicated graphics card! I read a copy of PC Powerplay in the 90's which convinced me onboard graphics are rubbish compared to the worst video card available at a given time, but he builds his own computers and is therefore an expert. (once he relented and bought the cheapest graphics card he could get, The Witcher looks a thousand times better! Hooray for my one piece of PC "knowledge"!)

They could have levels that don't have to load up every 30 paces.

And to answer your question more specifically: no. General purpose RAM won't have a big effect on graphics. The video-RAM on the graphics cards will make a huge difference to graphics (surprise surprise).

I had a closer look at the architecture of the 360 and an increase in RAM would improve it. Similar to onboard graphics with PCs, the CPU and Graphics processor share a pool of RAM. In the case of a PC this situation sucks, but in the case of a console the hardware is specifically designed to exploit the fact that it only needs to do one thing really well (play video games).

Didn't they do this with the PSP?

EDIT: Yep, from the PSP 2000 onwards it had double the RAM (32MB -> 64MB. Unsure if it makes any difference though.

RAM was pretty expensive (relatively) when the 360 was first released but given it would hardly be a greater expense to double the RAM in the 360 (if anyone even makes such small amounts of RAM anymore...) would an increase improve loading times for existing games or would the software have to be altered to take advantage of it?

I'm fairly sure software would have to be altered.
