RAM, and it's effect on performance with a CPU/GPU

I want to clarify my understanding of CPU+GPU+RAM.

Assumptions: Intel Core i3 + Intel HD 4000 GPU is > than AMD A-6 5200 + AMD Radeon 8330
(both are integrated GPUs, the i3 is slightly better than the A-6)

If the Intel combo had 4 GB RAM, and the AMD combo had 6 GB, would the AMD then match/outperform the intel combo? If you have an integrated graphics card, it uses more system RAM and therefore more RAM is better, or can make up for speed when you have integrated GPUs, is that how it works?
 
Solution
Of the two the Intel handles resources better, (memory management, et al), plus the CPU is more powerful, so think you'd be better off with the Intel - if it's in your budget, upgrading the DRAM would be another positive boost
If assumptions: i3+HD4000 +4GB RAM, and other laptop A6-5200 +HD8400 (not HD8330) +6GB RAM.
Then I will go with the A6 one it will much better for games because HD8400 (even HD8330) will be better than intel HD4000.

Because they share the RAM for laptop, if you have 6GB that will be better than 4GB.

Ok thanks. This is what I thought. However bench marks for the HD 4000 http://www.notebookcheck.net/Intel-HD-Graphics-4000.69168.0.html seem very good for dota 2, whereas the HD 8330 http://www.notebookcheck.net/AMD-Radeon-HD-8330.92874.0.html is severely worse. Given that the 8400 is only slightly better, wouldn't this show the 8400 to actually be worse than the Intel one?
