Athlon Vs. Atom: Duel Of The Energy Savers

AMD Athlon 64 vs. Intel Atom

AMD and Intel both use 300 mm wafer disks in their production lines. At 77 mm², the Athlon 64 2000+ is more than three times larger than the Atom at 24 mm², which means Intel can produce and sell three times as many CPUs. in fact, Intel can get about 2,500 processors per wafer, while AMD can get only about 800.

The Athlon 64 2000+ has 122 million transistors, and the Atom 230 only 47 million. If you look at the relationship between the number of transistors and energy consumption, a single Athlon 64 transistor uses less energy than an Atom transistor, even though Intel produces it using a 45 nm process while AMD relies on 65 nm manufacturing.

The Athlon 64 2000+ (OPN ADF2000IAV4DRE) runs on the Lima core at stepping G0. The HyperTransport frequency is 1000 MHz. This, of course, saves additional energy versus AMD’s more modern Phenom X3 and X4 CPUs. The Athlon 64 is on the same level as the Atom in terms of multimedia extensions, and the 64-bit instruction set has also been implemented.
