NForce3
The nForce3 chipset was created by Nvidia as a Media and Communications Processor. Specifically, it was designed for use with the Athlon 64 processor. Features of the nForce3 When the Athlon 64 was launched, the Nvidia nForce3 Pro150 and VIA K8T800 were the only two chipsets available. The 150 chipset was widely criticized at launch for using a 600 MHz HyperTransport interface, when VIA had implemented the full AMD specification at 800 MHz, even though overall performance of the 150 was still good. Later revisions fixed this omission, and using a HyperTransport interface, the nForce3 chipset is able to communicate at up to 8 GB/s with the CPU. This reduces system bottlenecks when using high-bandwidth devices. For example, the Gigabit Ethernet transmits at 125 MB/s; if the Ethernet were not on the chipset, a saturated gigabit Ethernet link would use 93% of the bandwidth of the shared 133 MB/s PCI bus. The 150 also noticeably lacked features. Subsequent revisions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HyperTransport
HyperTransport (HT), formerly known as Lightning Data Transport, is a technology for interconnection of computer processors. It is a bidirectional serial/ parallel high- bandwidth, low- latency point-to-point link that was introduced on April 2, 2001. The HyperTransport Consortium is in charge of promoting and developing HyperTransport technology. HyperTransport is best known as the system bus architecture of AMD central processing units (CPUs) from Athlon 64 through AMD FX and the associated motherboard chipsets. HyperTransport has also been used by IBM and Apple for the Power Mac G5 machines, as well as a number of modern MIPS systems. The current specification HTX 3.1 remained competitive for 2014 high-speed (2666 and 3200 MT/s or about 10.4 GB/s and 12.8 GB/s) DDR4 RAM and slower (around 1 GB/similar to high end Solid-state drive#Standard card form factors, PCIe SSDs ULLtraDIMM flash RAM) technology—a wider range of RAM speeds on a comm ...

NForce4
The nForce4 is a motherboard chipset released by Nvidia in October 2004. The chipset supports AMD 64-bit processors (Socket 939, Socket AM2 and Socket 754) and Intel Pentium 4 LGA 775 processors. Models nForce4/nForce4-4x nForce4 is the second evolution of the Media Communications Processor (MCP) and incorporates both Northbridge and Southbridge on a single die (the first was nForce3). The Socket 754 version of the board has the HyperTransport link clocked to 800 MHz (6.4 GB/s transfer rate). Motherboards based on early revisions are mostly referred to as "nForce4-4x" (relating with their ability to handle HT speeds of 4x). *Support for up to 20 PCI Express (PCIe) lanes (up to 38-40 lanes for the nForce4 SLI x16). Reference boards are set up with one x16 slot and three x1 slots, leaving 1 lane unused. *Support for up to 10 USB 2.0 ports. *Support for 4 SATA and 4 PATA drives, which can be linked together in any combination of SATA and PATA to form a RAID 0, 1, or 0+1. ...

NForce2
The nForce2 chipset was released by Nvidia in July 2002 as a refresh to the original nForce product offering. The nForce2 chipset was a platform for motherboards supporting AMD's Socket A CPUs along with DDR SDRAM. There were multiple variations of the chipset including one with an integrated GeForce4 MX graphics processor (IGP), and one without. Development The nForce2 features two different southbridges, the MCP and the MCP-T. The two differ only in audio and Ethernet integration. The latter is equipped with two 100 Mbit Ethernet NICs (nV and 3Com 3C905) and the NVAPU ( SoundStorm) with hardware accelerated 3D audio and real-time 5.1-channel Dolby Digital encoding, whereas the first features one 100 Mbit NIC and an AC'97 audio controller. For audio, both MCP units were connected to an external codec chip, such as a Realtek ALC650. With the MCP, this codec provided all software-driven audio duties, while with the MCP-T it performed the DAC duties. Unfortunately, the ex ...

Northbridge (computing)
In computing, a northbridge (also host bridge, or memory controller hub) is one of two chips comprising the core logic chipset architecture on a PC motherboard. A northbridge is connected directly to a CPU via the front-side bus (FSB) to handle high-performance tasks, and is usually used in conjunction with a slower southbridge to manage communication between the CPU and other parts of the motherboard. Since the 2010s, die shrink and improved transistor density have allowed for increasing chipset integration, and the functions performed by northbridges are now often incorporated into other components (like southbridges or CPUs themselves). As of 2019, Intel and AMD had both released chipsets in which all northbridge functions had been integrated into the CPU. Modern Intel Core processors have the northbridge integrated on the CPU die, where it is known as the uncore or system agent. On older Intel based PCs, the northbridge was also named external memory controller hub (''MC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sempron Sempron has been the marketing name used by AMD for several different budget desktop CPUs, using several different technologies and CPU socket formats. The Sempron replaced the AMD Duron processor and competed against Intel's Celeron series of processors. AMD coined the name from the Latin '' semper'', which means "always", to suggest the Sempron is suitable for "daily use, practical, and part of everyday life". The last Semprons were launched in April 2014. The brand was retired with the launch of the AMD A-Series APUs. History and features The first Sempron CPUs were based on the Athlon XP architecture using the ''Thoroughbred'' or ''Thorton'' core. These models were equipped with the Socket A interface, 256 KiB L2 cache and 166 MHz Front side bus (FSB 333). Thoroughbred cores natively had 256 KiB L2 cache, but Thortons had 512 KiB L2 cache, half of which was disabled and could sometimes be reactivated with a slight physical modification |
