We heard a lot about the hassle developing for PS3, and now John Carmack, the technical director of id Software has reaffirmed it.
“PS3 has more raw CPU power, but 360 has more GPU, avail memory, and is easier to develop for.” he said in his Twitter account.
Although with the statement above, he did say that the differences between Xbox 360 and PS3 are “modest” enough.
“The differences between the PS3 and 360 are modest enough that differences between developers is a much larger factor.” he added.
Xbox 360 features 3.2 GHz PowerPC with 3 dual-threaded processor cores and PS3 3.2 GHz Cell processor with 7 single-threaded synergistic processing units cores although is not directly comparable to Xbox 360 processor cores.
For RAM, Xbox 360 have 512 MB GDDR3 RAM (700 MHz), shared with GPU while PS3 is powered with 256 MB XDR RAM (3.2GHz).
