| Final-Fan said: sieanr, the RAM speeds, bandwidth, and architecture in both the 360 and the PS3have been dicussed very, very extensively in this thread, and it it ridiculous to claim that your 'objection' hasn't been addressed, even if MikeB never responded to your specific post. If you have issues with specific numbers, give your own sources with what you consider the true numbers.   |
The main part I take issue with is this; The clock speeds he cites and overlooking the disadvantages to XDR (namely very high latency). Not to mention the completly out of whack implication that the 360 design is like a cheap mobo.
A great specced CPU and GPU would be useless if the system has to deal with slow memory and not enough bandwidth to move around the data quickly enough.
The PS3 has 2 types of main memory, very fast 256 MB XDR DRAM with a clock rate of 3.2 GHz and slower 256 MB GDDR3 memory clocked at 700 MHz.
The Xbox 360 has a unified memory model with 512 MB GDDR3 running at 700 Mhz, similar to some cheaper boards or many Mini-ITX PC motherboards.
Like is the case on the PC, a unified memory model at a lower clock speed is a significant disadvantage. On the PS3 unlike is the case on ordinary PC motherboards both the CPU and GPU can access the faster system memory.
