With data being transferred 64 bits at a time per memory module, DDR3 SDRAM gives a transfer rate of (memory clock rate) × 4 (for bus clock multiplier) × 2 (for data rate) × 64 (number of bits transferred) / 8 (number of bits in a byte). Thus with a memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of 6400 MB/s.

To improve throughput, GDDR3 memory transfers 4 bits of data per pin in 2 clock cycles. The GDDR3 interface transfers two 32 bit wide data words per clock cycle from the I/O pins. Corresponding to the 4n-prefetch a single write or read access consists of a 128 bit wide, one-clock-cycle data transfer at the internal memory core and four ...
DRAM SO-DIMM. In 2002, the United States Department of Justice, under the Sherman Antitrust Act, began a probe into the activities of dynamic random-access memory (DRAM) manufacturers in response to claims by US computer makers, including Dell and Gateway, that inflated DRAM pricing was causing lost profits and hindering their effectiveness in the marketplace.
LPDDR3 went mainstream in 2013, running at 800 MHz DDR (1600 MT/s), offering bandwidth comparable to PC3-12800 notebook memory in 2011 (12.8 GB/s of bandwidth). [11] To achieve this bandwidth, the controller must implement dual-channel memory. For example, this is the case for the Exynos 5 Dual [12] and the 5 Octa. [13]
The sole principal change from AM2+ to AM3 is support for DDR3 SDRAM. The fastest CPU for socket AM3 is the Phenom II X6 1100T . Like the previous AMD socket, the "AM3 Processor Functional Data Sheet" (AMD document number 40778) has not been made publicly available.
DDR3 triple-channel architecture is used in the Intel Core i7-900 series (the Intel Core i7-800 series only support up to dual-channel). The LGA 1366 platform (e.g. Intel X58) supports DDR3 triple-channel, normally 1333 and 1600Mhz, but can run at higher clock speeds on certain motherboards.
