Difference between Willamette and illamette and Northwood and Prescott and Banias cores

Of course, it's the former, the Willamette core is the process, and the North wood core is the 478-pin CPU with the highest efficiency, although the second slow is only 512K, but the performance is better than the Prescott core at the time, 1M second slow P4 performance.

The Northwood P4 uses a micron step process, and secondly, its L2 cache will be 512KB, which can be said to be crucial for the speed performance of the CPU. Thirdly, the Northwood P4 will start with a QDR (Quadruple Frequency) mode of 133MHz, which is at least 533MHz external frequency.

The core, codenamed "Prescott", is based on an advanced micron process and uses an 800MHz front-end bus frequency. The "Prescott" has twice the number of transistors compared to the "Northwood" core, the L2 cache has been increased to 1M, and supports the SSE3 multi** instruction set with 13 instructions added and the Hyper-Threading (HT) technology. The original 8K L1 data cache has doubled to 16K, the instruction cache remains unchanged to 12K, and the L2 cache has increased to 1MB, but its pipeline has been lengthened from 20 to 31 in Northwood, and the increase in L2 cache is only to increase its branch ** hit rate to make up for the performance loss caused by its ultra-long pipeline.

When did the upstairs happen, prescott is very common now.

In the era of 478 needles, the most efficient P4 core is Northwood, although Prescott's second slow and new, but immature, heat and power consumption. At that time, the price of the P4 C series (N) at the same frequency was higher than that of the E series (P), and the performance was also stronger than that of the E series.

But by the time of the 775 stitches, there was no northwood core and, so there was no comparison.

If it's the same series, of course, it's the Prescott core, like the same P4 or Celeron.

It's not that it's not very comparable to the same series, for example, the P4 at the Northwood core is definitely a little better than Prescott's Celeron.

Mine is Willamette, which should be able to share more than 845d, 478pin

What price do you want to buy?

These three core codenames are already relatively old......
