Thus, DDR2 memory must be operated at twice the data rate to achieve the same latency. Another cost of the increased bandwidth is the requirement that the chips are packaged in a more expensive and difficult to assemble BGA package as compared to the TSSOP package of the previous memory generations such as DDR SDRAM and SDR SDRAM. This ...
Mobile PCI Express Module (MXM) is an interconnect standard for GPUs (MXM Graphics Modules) in laptops using PCI Express created by MXM-SIG. The goal was to create a non-proprietary, industry standard socket, so one could easily upgrade the graphics processor in a laptop, without having to buy a whole new system or relying on proprietary vendor upgrades.
The 360PE cost $300 more than the 360P at $3,699. IBM ThinkPad 360CE — One of the final models, the 360CE was a slight upgrade from the earlier 360/C/CS models, offering a Intel 486 DX2 running at 50 MHz, a 8.4-inch 640×480 TFT display, and an additional 540 MB option for hard disk size. Other features included: Ultrabay with 1.44 MB floppy ...
Many computer systems have a memory hierarchy consisting of processor registers, on-die SRAM caches, external caches, DRAM, paging systems and virtual memory or swap space on a hard drive. This entire pool of memory may be referred to as "RAM" by many developers, even though the various subsystems can have very different access times ...
As with earlier memory generations, faster DDR3 memory became available after the release of the initial versions. DDR3-2000 memory with 9-9-9-28 latency (9 ns) was available in time to coincide with the Intel Core i7 release in late 2008, [ 19 ] while later developments made DDR3-2400 widely available (with CL 9–12 cycles = 7.5–10 ns), and ...
Since the cost of processing a silicon wafer is relatively fixed, using smaller cells and so packing more bits on one wafer reduces the cost per bit of memory. Memory cells that use fewer than four transistors are possible; however, such 3T [ 27 ] [ 28 ] or 1T cells are DRAM, not SRAM (even the so-called 1T-SRAM ).

Building a computer at home is generally considered a cost-effective alternative to buying a pre-built one because it excludes the assembly labor cost. However, the total cost of building a computer can vary based on an individual's budget, the quality and availability of the parts used, and the discounts offered by mass production.
