1. There is diminishing return on larger L2 caches (after some point you still have to go to the ram).

Also, Hyper-Threading is a joke of a technology in terms of raw performance. Just read the Wikipedia article on it.

Granted, on older P4, the hyper threading was great for multitasking.

Dual core with Hyper-threading? WTF?

2. I own a QX6700. When i use it with Autodesk Maya it sees it as 8 threads not four. On my other PC with one "old" P4 (with hyperthreading) Maya sees this as two threads. I assumed the QX was because of hyperthreading yet you guys say its not supported.

3. If Intel calls it Hyper threading again
it will be like a green grocer painting an apple Orange
and selling it as a Navel Orange

Pentium 4 only could do 1 thread at a time and HyperThreading manipulated the rediculously long pipeline which rarely was filled by a task to 'emulate' 2 threads.
(hense why it caused a performance hit in heavy loads)


This time around i'm hoping Intel will allow two true native threads like Sparc, PowerPC and Cell support.
Each core can do 2 - 8 threads each depending on the processor.
AMD and Intel can do 1 per core
Pentium 4 W/HT could do 1&1/2
