Intel "Nehalem" Chip Design Demo'd for Developers

Intel's Pat Gelsinger demos Nehalem, Intel's next chip design, at the Intel Developer Forum in San Francisco August 2008. New designs has new features built in like Turbo Mode for performance and energy efficiency. See 3-D visualization, game and weather modeling demonstrated using Nehalem designed computer processors.

NEHALEM = R.I.P. AMD

[doseryder]

Nehalem is a Michael Phelps on silicon lolz

there may be a useful number of processors but 4 cores is still a low number of cores. if the program is threaded well enough, it should make use of all those cores. we dun design programs to use only certain cores. we design it to be threaded and let a system to handle those threads

[shearerforgold]

that is stupid of course some programs can only use 2 cores if that is what they are coded for, u r talking smack

[chrisc62]

Amdahl's law puts a limit to the useful number of processors for any computation. Some processes for instance reading an input file are typically single threaded, even if subsequent computation on that data may be parallelized,

[fireicer]

That might be because intel finally made the jump to move the memory controller directly on to the processor die. previous ddr and ddr2 generation arch had the memory controller outside. Its a shame because designers now cant choose the memory types to use with this processor but for the end user its a sure leap in high bandwidth. Not as much as it could be mind you.

[fireicer]

very very true. Intel keep bragging about this chip being scalable but at £1200.00($1700.00) per processor of 4 cores 8 threads this is not a practical processor. to produce petaflop speed with this arch requires still too much power, still way to much size and price.

[lampuiho]

That's not the truth. If a program can make use of multicore proccessors, then it can make use of any number of cores. No software designer designs a program that only runs on a specific number of cores.

2:00 Lost Planet is one of the best looking games and technically way beyond other games in this generation.

[FSFchannel]

does not* i meant at the end.

[FSFchannel]

erm, DDR3 RAM just means its running at faster frequencies, which thus means the bandwidth is much greater. That means applications are cached faster. There is no program that does fully use RAM.

nehalem is a hyper threading quad core its not actually 8 physical cores.
