Tonight AMD has officially released their 760MP chipset along with 1 and 1.2GHz versions of their Athlon MP CPUs.  The GHz will cost $215 and the 1.2GHz will cost $265 in quantities of 1,000.  Tyan has also released their Thunder K7, the board I've been following since it was known as the Dolphin back at Comdex 1999.  First let's take a look at the Athlon MP cpu that AMD recommends for use with the 760MP chipset.

The Athlon MP is based on the Palomino core which is the same core as the mobile Athlon 4.  There are a few major differences between the Palomino core and the Thunderbird core used in the current desktop Athlon.

  Athlon (Thunderbird) Athlon MP (Palomino)
CPU Interface Socket A Socket A
Fabrication Process .18µ .18µ
Number of Transistors 37 million 37.5 million
Die Size 120mm² 128mm²
Relative Power Consumption -- 20% reduction
3DNow! Version Enhanced 3DNow!™ 3DNow! Professional™
Onboard Cache  384k 384k with data prefetch

The Socket A interface of the Athlon MP is the same as that of the Athlon.  In fact AMD plans on using the Socket A interface at least thru the end of 2002 with their Thoroughbred and Barton CPUs.  Look for Socket A to be around for some time to come.  The process of the SMP Athlon also remains at .18µ and will not change until the Thoroughbred core in the first half of 2002. 

With the new CPU the number of transistors has increased slightly from 37 to 37.5 million.  With this increase the die has also grown from 120mm² to 128mm².  Thanks to the improvements to the Palomino core the power consumption has decreased roughly 20% even though the CPU has grown in size. 

So what has brought about this growth in CPU die size?  The inclusive L1 cache with data prefetch along with 52 new 3DNow! instructions are the culprits.  Data prefetch is thought to lead to the bulk of the performance increase with the Palomino core.  The increase can be up to 15% due to data prefetch and 3DNow! Professional.
