Flaw Delays Shipment Of New 'Canterwood' Pentium 4
bigal3du writes "Hardware-Unlimited has posted new information from Intel that they will be delaying the shipment of the new Pentium 4 3Ghz with an 800Mhz FSB. An Intel spokesman contacted Hardware-Unlimited early this morning to let the publication know that performance "anomolies" have been discovered, at the last minute, in validation testing and the processor will be temporarily delayed for shipment. Full details on Hardware-Unlimited.com Forums..." ninenet points to this PC Magazine article which explains the things that characterize the new chip and also mentions the delay.
The Inquirer like everyone else has updated their story...:
Update It would appear that the original version of the story was correct. Intel has put the 800MHz FSB 3.0GHz P4 on hold. We received the following statement from Intel: "Due to recent analysis, and given our commitment to quality, Intel will be placing the Pentium 4 processor at 3.00 GHz with an 800MHz bus on ship hold temporarily. In the course of our final testing in our validation lab environment, we have observed an anomaly on a very small number of the 800MHz bus processors. We are working to understand and resolve the issue and we hope to ship this new processor as soon as possible."
- what is the definition of simultanagnosia?! I've been meaning to look it up!
3 GHz = 3000 MHz.
3 GHz != 3096 MHz
Therefore
3000 Mhz / 1.023 MHz = 2932.551
MHz and GHz are base 10. Base 2 is for memory.
"I won't mod you down - I feel the need to call you a twit explicitly, rather than by implication."
Its such a tired argument, really. The fact is, the Pentium4 clocks awsomely by design, with an (intentional) tradeoff in IPC, while the Athlon is the opposite. They are both neck and neck now performance wise. So many people think that Intel "screwed up" on the IPCs. This is complete bullshit, they just took a different tactic.
The Pentium M is essentially a modified P3, which extra cache, SSE2 and a faster FSB. Since the P3 was at least in the same IPC ballpark as the Athlon, I'm sure the M is going to clean up at similar clockspeeds. However, again, it doesn't clock as high.
Just different tactics, they are all really quite comparible from a design (and performance) point of view. The only problem is the public perception of MHz being the only factor. For some reason this does not occur in the video card market, just in CPUs.

Floating point operations using integers on Pentium Is returned non-integer values. Let's take 2,0 divided by 2,0. The result of the previous division for example could have been 0,99999959335. Feel free to correct me if i'm wrong (And i'm sure someone will).
