CHIEF SCIENTIST David Kirk told the Hot Chips conference at Stanford University that programming technology faces problems because of multithreading and multicore introductions.

The EE Times reported Kirk as saying that chip architects are moving quickly to multicore and multithreading designs but that could mean a slowdown to graphics performance.

One problem with multicore CPUs is that gaming programmers find them hard to exploit, with the second core providing no appreciable benefit.

Applications can run slower on multicore processors while graphics processors are "embarrasingly parallel", said the EE Times, here.

The Geforce graphics chip used for the Playstation 3 provides more floating point operations than the Cell chip it\'s supposed to support, he said.

Nice to hear that rsx is capable of more Fp ablities than cell, not that cell\'s FP really was something to brag about in terms of advantage in regards to practical real world game performance, more of a marketing thing.

It\'s seems alot of people in the industry are begining to speak out/express there apprehension for Dual cores chips.

Me thinks it\'s gonna take a console generation before developers really begin to understand and become skilled in Symmetrical Multi Processing coding.

I think they need to suck it up and learn how to develop for multicore CPUs.

I thought Nvidia was happy with the Cell

Didn\'t Nvidia develop a customized GPU for the Cell and PS3 ??:D .....and yes they were happy....

And you think ATI is any better?  They can\'t even get their GPU to compete with the 7800GTX out the door.  No, MS screwed themselves by not buying the license to build the nvidia chip in the xbox themselves.  MS tried strongarming them into lowering their price, but Nvidia needed to make money off the xbox too.
