Intel Madison, the power of the 6MB cache?

First came the Merced, followed by the McKinley and now the Intel 64 bit processor with the code name Madison is supposed to fix it. In view of a cache that has doubled to 6 MB and a processor clock that has been increased to 1.5 GHz, this goal seems to be easily achievable.

The processor core, which is also produced in 130nm like the Pentium 4 core 'Northwood', has 410 million transistors, which are spread over an area of ​​377 mm² and divert no less than 130 watts from the power supply. The 130nm Pentium 4, on the other hand, 'only' has 55 million transistors with a size of 131 mm² and is therefore already significantly more complex than the Athlon XP (Thoroughbred). Compared to McKinley, aka Itanium 2, the new one can almost be described as 'small'. Because this was still made in the somewhat outdated 180nm technology. And although the McKinley can only fall back on 3 MB integrated cache, it is even slightly larger at 421 mm².

Intel assumes that the overall server performance is achieved by the Madison compared to the Itanium 2 to be able to increase by 50 percent, but the new processor will not be more expensive than its predecessor. A target price of 4,200 US dollars is likely. Incidentally, the Madison should not come on the market as Itanium 3. Intel will choose a variation of the brand name Itanium 2, which is already in use.

The successor to the Madison will be the 90nm Montecito. However, this should not appear until 2003.
