No. I completely disagree with this statement but I see a lot of people stating it in graphics threads about PS4 vs. nextbox. If you are one of the people saying this, please explain yourself.

There are two reasons why some may compare Sony's use of GDDR5 memory with the Cell processor.
1. Cost. Despite the estimates given, GDDR5 memory is expensive. Both in monetary cost and realestate. Currently GDDR5 memory is only available in 16MB chips, meaning they require much more space in order to achieve 4GB let alone 8GB.
2. The speed has limited benefit. Currently there is limited benefit to having so much fast memory. A program gets loaded into memory and there it stays until it's shut down. There's no speed benefit except for the loading part. The faster memory does have an advantage for graphics, but there again largely with the initial loading. Once a game is running, the benefit of the larger memory is negligable because of the solution Microsoft adopted.
The cost vs. gain is small. That being said, where the two diverge (Cell vs. GDDR5 memory) is that GDDR5 memory is a simple solution to a simple problem, and the long-term benefits aren't known. Microsoft took a more technological solution to the problem. The Cell processor was technological overkill for a simple problem. A marvel, mind you, but overkill. Akin to putting military grade ICs in action figures e.g. Toy Soldiers.
If this generation of consoles is short lived, say 5 years, I don't believe Sony's gamble will pay off. If this generation is another 10 year generation, then I think it'll pay off. It won't necessarily mean a significant performance leap ahead of Microsoft, but the cost of investment will pay off. But it's a big chunk of money for Sony to spend.
Also, I personally would be afraid of any developer that gets all giddy when he/she sees 8GB of memory. The beauty of hardware constraints are that developers are forced to write clean, efficent code. I am loathe to imagine what kind of sloppy code that will be generated because developers have such a large quanity of memory to work with on both machines, irrespective of speed. One day it'll be used wisely, but for about two years I think we'll see lots of patched games to fix bad code.
