What's advantage CPU Pentium 4 90nm Technology?

Question

Do you know 90nm and 65nm difference?

Answer 1

Yes, the 65nm will run MUCH cooler than a 90nm part, even if both are running at exactly the same speed, and are installed in exactly the same case.

Answer 2

The 90nm Pentium 4 processor features 16KB of data cache, compared to 8KB on the 0.13 micron Pentium 4 processor. In addition to the data cache, the Pentium 4 processor includes an Execution Trace Cache that stores up to 12,000 decoded micro-ops in the order of program execution. By storing those decoded micro-ops, the Execution Trace Cache effectively removes the decoder from the main execution loop and makes more efficient usage of the cache storage space, since instructions that are branched around are not stored.
The 90nm process-based Pentium 4 processor increases the L2 Advanced Transfer Cache to 1MB from its previous level of 512KB on the 0.13 micron process-based Pentium 4 processor. The Level 2 Advanced Transfer Cache delivers a much higher data throughput channel between the Level 2 cache and the processor core. The Advanced Transfer Cache consists of a 256-bit (32-byte) interface that transfers data on each core clock. As a result, the Pentium 4 processor at 3.40 GHz can deliver a data transfer rate of 108 GB/s. This compares to a transfer rate of 16 GB/s on the Intel® Pentium® III processor at 1 GHz.
The larger on-die L2 and L1 data cache improves overall application performance by holding more data close to the processor. The increased size of the L1 and L2 caches is important to the performance associated with Hyper-Threading Technology, since these caches are shared among logical processors.

90nm and 65 nm are only for overclockers mainly.
the lower the nm number is, the more you can overclock.
old cpus were 120nm, you culd barely overclock them .1ghz if any at all
90nms will allow about a 30% overclock on stock air cooling
30 nms (very very rare, but awesome to have) will allow anywhere from a 40% overclock to 80% overclock on air cooling (my friend did 80% on an AMD 3200+, lucky guy, but anyways, if you use a phase changer or water cooler, you can get a goo 100% overclock to 130%, very unheard of but very much possible.
