If the 360 had 8GB of GDDR3 RAM + BC,but made compromise against 8GB RAM GDDR5

The gddr5 is only about 10% faster than gddr3. And while ram is important, gpu and cpu are vastly more important.


What are you basing that on? At similar clockrates and all other aspects being equal, GDDR5 is just under 2.5 times as fast as GDDR3:

Part of the reason GPUs are as fast as they are is BECAUSE of the RAM they use. Why do you think the PS3's GPU had so many performance issues?


The only thing with this is I don't see any reason that RAM needs to be that fast. Unless they're gonna pull off something seriously hardcore with it, it's highly unnecessary to have GDDR5 outside of the video card especially considering PCs are running with standard DDR3. It doesn't need to process as fast.

Well, the fact that the GPU will be utilizing it regardless makes GDDR5 worthwhile alone. Moreso when BOTH the CPU and GPU are going to be accessing it, meaning that it essentially needs to be fast enough to handle not only the requirements that system-level DDR3 would as well as taking up the requirements that the GPU puts onit. That's one reason that integrated laptop GPUs are so much slower than desktop GPUs: not only is the GPU using DDR3, but the CPU is accessing it too, so they effectively slow eachother down.

DDR3 would be fine for general system operations, but on a system with unified RAM like a console where multiple components are relying on it (especially a bandwidth-hungry part like the GPU), speed becomes much more important.

While ddr5 is better, actual factor is how many shader units the GPU has

For example, can the GPU do 50 Shades of Grey?

I read that book. It was okay I thought it was supposed to be a good story. But eh, I don't see why so many people like it.
