Intel Quad-core processors are only the beginning of what a revitalized Intel has to offer, the company's top executives said here Sept. 26. The chip maker will deliver in November its first quad-core processors - chips that incorporate four processors each - for both desktops and servers, said CEO Paul Otellini here, in an opening keynote speech at the Intel Developer Forum. The quad-core chips themselves will offer up to 70 percent greater performance in desktops and 50 percent in servers.

Member since:

however with 4 cores (and fast cores at that) in today's desktops i think there is going to be a lot of people firing up their multithreaded hd video encoder and wondering why each core is only running at 60% load.

"Test results with the software packages Main Concept with H.264 encoding and the WMV-HD conversion make this very clear. We noticed performance jumps of up to 80% when compared to the Core 2 Duo at the same clock speed (2.66 GHz)."

they will be hitting other bottlenecks, the bus will become saturated with disk io traffic and memory accesses. i'm sure someone can crunch the numbers and get a rough estimation of the impact of this phenomenon.

"Our test results reveal that a FSB1333 (true 333 MHz) does not entail advantages - at least not based on the tests at a CPU clock speed of 2.66 GHz. At CPU clock speeds of 3.0 GHz and above, and memory speeds beyond the DDR2-1000 mark (true 500 MHz), the FSB1333 shows what it is capable of.

One should not forget - viewed from the perspective of the Pentium 4 - that the Core 2 micro-architecture offers a few features to ease the strain on memory access, whereby higher FSB or memory speeds barely register any speed advantages."
