The EDRAM may seem small, but you are forgetting that if the PS3 needs the same amount of texture memory as the 360, it has to eat into its fram buffer as well. Remember that the PS3 has 256MB+256MB=512MB, but the 360 has 512MB+10MB. So even assuming the EDRAM does not have speed to make up for its size, a PS3 game using about 256MB of texture memory would have just as small an amount for its frame buffer.
The EDRAM is really just special purpose memory, but it's really too small to work with for high resolution graphics. The memory bandwidth is far more relevant as 512 MB is more than enough to work with despite what some may claim, regarding memory the PS3 has Blu-Ray to constantly stream new data (much more than would be possible with CD or DVD) and the PS3 has a harddrive by default, look at the harddrive as something similar to virtual memory on a PC being able to stream data much faster than a DVD or Blu-Ray disc. Apart for those crucial facts the PS3 has more than 512 MB memory to deal with, there are for example also high speed local memory stores for each SPE, very neat indepent processors with which you can create lots of effects and other complex calculations.
