'''Jean-Baptiste Carpeaux''' ([[May 11]], [[1827]], [[Valenciennes]] –[[October 12]], [[1875]], [[Courbevoie]]) was a French sculptor and painter. His early studies were under [[François Rude]]. Carpeaux won the [[Prix de Rome]] in [[1854]], and moving to [[Rome]] to find inspiration, he there studied the works of [[Michelangelo Buonarroti|Michelangelo]], [[Donatello]] and [[Andrea del Verrocchio|Verrocchio]]. Staying in Rome from [[1854]] to [[1861]], he obtained a taste for movement and spontaneity, which he joined with the great principles of [[baroque art]]. In [[1861]] he made a bust of [[Mathilde Bonaparte|Princess Mathilde]], and this later brought him several commissions from [[Napoleon III]]. He worked at the pavilion of [[Flora (goddess)|Flora]], and the [[Opéra Garnier]]. His group La Danse (the Dance, [[1869]]), situated on the right side of the façade, was criticised as an offence to common decency.

He never managed to finish his last work, the famous Fountain of the Four Parts of the Earth, on the Place Camille Jullian. He did finish the terrestrial globe, supported by the four figures of [[Asia]], [[Europe]], [[North America|America]] and [[Africa]], and it was [[Emmanuel Frémiet]] who completed the work by adding the eight leaping horses, the tortoises and the dolphins of the basin.

'''DDR3 SDRAM''' or '''[[double data rate|double-data-rate]] three [[SDRAM|synchronous dynamic random access memory]]''' is the name of the new [[double data rate|DDR]] memory standard that has been developed as the successor to [[DDR2 SDRAM]].

The memory comes with a promise of a power consumption reduction of 40% compared to current commercial DDR2 modules, due to DDR3's [[90 nm]] fabrication technology, allowing for lower operating [[Electric current|currents]] and [[voltages]] (1.5 V, compared to DDR2's 1.8 V or DDR's 2.5 V). "Dual-gate" transistors will be used to reduce leakage of current.

==Neapolitan Fisherboy==
DDR3's [[prefetch buffer]] width is 8 bit, whereas DDR2's is 4 bit, and DDR's is 2 bit.


Carpeaux submitted a plaster version of ''Pêcheur napolitain à la coquille'', the Neapolitan Fisherboy, to the [[French Academy]] while a student in [[Rome]]. He carved the marble version several years later, showing it in the Salon exhibition of 1863. It was purchased for [[Napoleon III]]'s empress, [[Eugénie de Montijo|Eugènie]]. The statue of the young smiling boy was very popular, and Carpeaux created a number of reproductions and variations in marble and bronze. There is a copy, for instance, in the Samuel H. Kress Collection in the [[National Gallery of Art]] in [[Washington D.C.]]
Theoretically, these modules could transfer data at the effective clockrate of 800-1600MHz (for a single clock bandwidth of 400-800MHz), compared to [[DDR2 SDRAM|DDR2's]] current range of 400-1066 MHz (200-533 MHz) or [[DDR SDRAM|DDR]]'s range of 200-600 MHz (100-300 MHz). To date, such bandwidth requirements have been mainly on the graphics market, where fast transfer of information between [[framebuffer]]s is required.


Some years later, he carved the Girl with a Shell, a very similar study.
Prototypes were announced in early 2005, while the DDR3 specification is expected to be publicly available in mid-[[2007]]. Supposedly, [[Intel]] has preliminarily announced that they expect to be able to offer support for it in mid 2007 with a version of their upcoming Bearlake chipset. [[AMD]]'s [http://www.amdcompare.com/techoutlook roadmap] indicates their own adoption of DDR3 to come in 2008.


Carpeaux sought real life subjects in the streets and broke with the classical tradition. The Neapolitan Fisherboy's body is carved in intimate detail and shows an intricately balanced pose. Carpeaux claimed that he based the Neapolitan Fisherboy on a boy he had seen during a trip to [[Naples]].
DDR3 DIMMs have 240 pins, the same number as DDR2; however, the DIMMs are physically incompatible, owing to a different key notch location. [http://www.simmtester.com/page/news/showpubnews.asp?title=Memory+Module+Picture+2007&num=150]

The [[GDDR3]] memory, with a similar name but an entirely dissimilar technology, has been in use for several years in high-end graphic cards such as ones from [[NVIDIA]] or [[ATI Technologies]], and as main system memory on the [[Xbox 360]]. It is sometimes incorrectly referred to as "DDR3".

Jean-Baptiste Carpeaux (May 11, 1827, Valenciennes –October 12, 1875, Courbevoie) was a French sculptor and painter. His early studies were under François Rude. Carpeaux won the Prix de Rome in 1854, and moving to Rome to find inspiration, he there studied the works of Michelangelo, Donatello and Verrocchio. Staying in Rome from 1854 to 1861, he obtained a taste for movement and spontaneity, which he joined with the great principles of baroque art. In 1861 he made a bust of Princess Mathilde, and this later brought him several commissions from Napoleon III. He worked at the pavilion of Flora, and the Opéra Garnier. His group La Danse (the Dance, 1869), situated on the right side of the façade, was criticised as an offence to common decency.

He never managed to finish his last work, the famous Fountain of the Four Parts of the Earth, on the Place Camille Jullian. He did finish the terrestrial globe, supported by the four figures of Asia, Europe, America and Africa, and it was Emmanuel Frémiet who completed the work by adding the eight leaping horses, the tortoises and the dolphins of the basin.

Sculptures by Carpeaux

Neapolitan Fisherboy

Carpeaux submitted a plaster version of Pêcheur napolitain à la coquille, the Neapolitan Fisherboy, to the French Academy while a student in Rome. He carved the marble version several years later, showing it in the Salon exhibition of 1863. It was purchased for Napoleon III's empress, Eugènie. The statue of the young smiling boy was very popular, and Carpeaux created a number of reproductions and variations in marble and bronze. There is a copy, for instance, in the Samuel H. Kress Collection in the National Gallery of Art in Washington D.C.

Some years later, he carved the Girl with a Shell, a very similar study.

Carpeaux sought real life subjects in the streets and broke with the classical tradition. The Neapolitan Fisherboy's body is carved in intimate detail and shows an intricately balanced pose. Carpeaux claimed that he based the Neapolitan Fisherboy on a boy he had seen during a trip to Naples.
