A UC Berkeley paper [PDF] recently submitted to the IEEE International Parallel and Distributed Processing Symposium manages to highlight two common and seemingly unrelated themes that have come up a number of times over the past few years in my reporting on the high-performance computing (HPC) space: 1) IBM's Cell is really good at HPC workloads when you invest the time to write custom code for it, and 2) Intel's Xeon platform is perennially bandwidth starved and not very power-efficient.
The Finals’ new Easter event is live now in Embark’s PS5 and Xbox FPS, as Bunny Bash ushers in free skins and more for a limited time only.
This is a fun game and it will be interesting to experience it in V.R. Play through a brand new story as you fight to gain a foothold in the perilous Overlands, battling the elements and the many colossal creatures that reside in the forest.
The ray tracing update Diablo IV on PC has been released, and if you're wondering whether there's a noticeable improvement, read ahead.

That's my PS3 and my PC(CPU) 1 & 2 :)
But like they explain, the benchmark test was written exclusive for the Cell as its architecture is vastly different from the others, but it seem the Cells knight in shining armor is the RDRAM.
who has it
is that proponents of Microsoft's machine always tout on about how the PS3 is "bottle-necked" for memory, and thus stifled in terms of performance.
In this study (which won an award, mind you), the Xeon was the processor most affected by memory, not the Cell. Aren't the processors in 360s some variant of Xeon architecture?
If so, it pretty much negates all those 'PS3/bottle-neck/ memory' rants, as the 360s on the short side of the stick here.
I'm not looking to flame, just looking for information.

no chris this is not the same xeon as in the 360, the xbox chip is called XENON, the 360's chip is made by ATI not Intel. IBM made both processors for the 360 an PS3 but Nvidia made the GRAPHICS chip for the PS3( cell doesnt do the graphics) an ATI made the graphics chip for the 360!!
Of course!!! ;-P
