Sempron

Sempron is a processor of line entry of AMD which replaces the Duron. In competition with the Celeron of Intel, it results from the variation of two architectures from AMD, K7 and K8

Sempron: Socket has

It connects on Socket has Athlon, Athlon XP and Duron, and is not other than a Athlon XP with core Thorton laying out of 256 Kio of mask of level 2 and a bus EV6 166 MHz GDR . The amputation of part of the mask of the Athlon XP equipped with the core Barton (512 Kio) confers a debatable interest to him. Only the version 3000+ has a mask of level 2 of 512 Kio.

To note that like all processors AMD of 7th generation (Athlon, Athlon XP, Athlon MP, Duron), Sempron Socket has a mask of level 1 of 128 managed Kio in an exclusive way, i.e. the contained informations in the mask of level 1 are not recopied in the mask of level 2.

It has Performance Ratings energy of 2200+ with 3000+ .

All equal parameters, it makes good match with Athlon XP. No major difference at the technical level, the difference being at the level marketing, the Performance Rating having been revalued with the rise to counter the Intel line entry: the Celeron.

Sempron: Socket 754

Second is based on architecture AMD64 and places on socket 754 like the Athlon 64 of first generation. Its difference with the Athlon 64 traditional lies in the fact that extensions 64 bit are decontaminated (except for the most recent versions, cf below). The excellent controller integrated report remains on the other hand part, which confers a quality positive ratio/price to him.

The mask of level 1 is of 128 Kio. As for the mask of level 2, it varies from 128 Kio with 256 Kio, making it possible AMD to propose several performance levels.

It has Performance Ratings energy of 2600+ with 3400+ .

Sempron: Socket AM2

The third grinding of Sempron is also based on architecture AMD64, but raises rather of the socket AM2. This support, itself derived from the sockets 939/940, brings like great innovation the storage medium DDR2, however presents since one good moment on the market. This makes it possible to benefit from a new beach of frequencies DDR2, going from 533 to 800 MHz, contrary with beach preceding DDR1 from 266 to 400 MHz. Several analysts deplore the weak performance profit Net brought because of important latency of the DDR2. Indeed, in spite of a doubled frequency, several branches of industry, in particular the video games, do not profit from an significant improvement.

Engraving remains with 90nm ONESELF, as it was the case with the versions on S754. The technology of energy saving Calm Cool' , arrived late on the models S754, is henceforth integrated into all the processors Sempron AM2, except for the models 2800+ and 3000+. Lastly, to this economy the distribution of model “EE is added”, for Energy Efficient , who make pass the electricity consumption of 62 W to 35 W.

The series, named Manila has Performance Ratings energy of 2800+ with 3600+ , for frequencies going of 1,6 GHz with 2,0 GHz.
