By 1990, Taiwanese companies manufactured 11% of the world's laptops. That percentage grew to 32% in 1996, 50% in 2000, 80% in 2007 and 94% in 2011. [5] [6] The Taiwanese ODMs have since lost some market share to Chinese ODMs, but still manufactured 82.3% of the world's laptops in Q2 of 2019, according to IDC. [7] Major relationships include: [8]
Despite popularity of its ThinkPad set of laptop PC's, IBM finally relinquished its role as a consumer PC manufacturer during April 2005, when it sold its laptop and desktop PC divisions (ThinkPad/ThinkCentre) to Lenovo for US$1.75 billion. As of October 2007, Hewlett-Packard and Dell had the largest shares of the PC market in North America.
In contrast with standard SDRAM, used in stationary devices and laptops and usually connected over a 64-bit wide memory bus, LPDDR also permits 16- or 32-bit wide channels. [2] The "E" and "X" versions mark enhanced versions of the specifications. They formalize overclocking the memory array by usually 33%.
The Model 1 had a list price of US$3,999 and was equipped with a 12 MHz Intel 80286, 640 KB RAM, 1.2 MB 5.25″ floppy, and a 10″ amber colored gas-plasma display. [8] Other options included the Model 20 at US$4,999 which added a 20 MB hard disk , [ 9 ] or US$5,799 for the Model 40 with the upgraded 40 MB hard disk. [ 7 ]
With data being transferred 64 bits at a time, DDR SDRAM gives a transfer rate (in bytes/s) of (memory bus clock rate) × 2 (for dual rate) × 64 (number of bits transferred) / 8 (number of bits/byte). Thus, with a bus frequency of 100 MHz, DDR SDRAM gives a maximum transfer rate of 1600 MB/s.
The Nintendo console used 4 MB RDRAM running with a 500 MHz clock on a 9-bit bus, providing 500 MB/s bandwidth. RDRAM allowed N64 to be equipped with a large amount of memory bandwidth while maintaining a lower cost due to design simplicity. RDRAM's narrow bus allowed circuit board designers to use simpler design techniques to minimize cost.
The separate JEDEC standard Low Power Double Data Rate 5 (LPDDR5), intended for laptops and smartphones, was released in February 2019. [15] Compared to DDR4, DDR5 further reduces memory voltage to 1.1 V, thus reducing power consumption. DDR5 modules incorporate on-board voltage regulators in order to reach higher speeds.
