The PS3 doesn't have 8 cores... it's a single core processor with with 8 SPEs... way different that a duo or quad core processor. A $100 Intel Corel 2 Duo processor is way faster than a PS3 Cell processor... |
wait wat? the fail palm its for you. a quadcore maybe but a 1.6ghz dual core isn't.
and the SPE are cpu, they even have 256kb of cache EACH.
from IBM:
All things considered the theoretic 204.8 GB/s number most often cited is the best one to bear in mind. The IBM Systems Performance group has demonstrated SPU-centric data flows achieving 197 GB/s on a Cell processor running at 3.2 GHz so this number is a fair reflection on practice as well.
The kernel and scheduling is distributed across the SPEs. Tasks are synchronized using mutexes or semaphores as in a conventional operating system. Ready-to-run tasks wait in a queue for an SPE to execute them. The SPEs use shared memory for all tasks in this configuration.
in comparison to the 360 CPU:
from IBM:
115.2 GFLOPS theoretical peak performance
Xenon is a Tri-Core CPU PowerPC based better than intel x86 cpus,
by force a very high clocked intel x86 or quadcore cpu is needed to match ps3 or even 360 cpu.
