Turion 64
Turion 64 is the brand name AMD applies to its 64-bit low-power (mobile) processors codenamed K8L [1]. The Turion 64 and Turion 64 X2 processors compete with Intel's mobile processors, initially the Pentium M and currently both of the Intel Core processors.
Turion 64 processors are compatible with AMD's Socket 754 and are equipped with 512 or 1024 KiB of L2 cache, a 64-bit single channel on-die memory controller, and an 800MHz HyperTransport bus. Battery saving features, like PowerNow!, are central to the marketing and usefulness of these CPUs.

AMD
Quad Core
The quad-core architecture, also known as "AMD K10" is AMD's new microarchitecture. The "AMD K10" microarchitecture is the immediate successor to the AMD K8 microarchitecture, and is expected due middle of 2007. K10 processors will come in a single, dual, and quad-core versions with all cores on one single die.
AMD Fusion
After the merger between AMD and ATI, an initiative codenamed Fusion was announced that merges a CPU and GPU on one chip, including 20 lane PCI Express link to accommodate external PCI Express peripherals, thereby eliminating the requirement of a northbridge chip, completely from the motherboard. It is expected to be released late-2008 or early-2009.
Other platforms and technologies
Alchemy Processors
In February 2002, AMD acquired Alchemy Semiconductor and continued its line of processor in MIPS architecture processors, targets the handheld and Portable media player markets. On 13 June 2006, AMD officially announced that the Alchemy processor line was transferred to Raza Microelectronics Inc.
AMD Live!
AMD LIVE! is a platform marketing initiative focusing the consumer electronics segment.
AMD Quad FX platform
The AMD Quad FX platform, being an extreme enthuusiast platform, allows two processors connect through HyperTransport, which is a similar setup to dual-processor (2P) servers, excluding the use of buffered memory/registered memory DIMM modules, and a server motherboard, the current setup includes two Athlon 64 FX FX-70 series processors and a special motherboard. AMD pushed the platform for the surging demands for what AMD calls "megatasking" for true enthusaists[citation needed], the ability to do more tasks on one single system.
Geode processors
In August 2003, AMD also purchased the Geode business which was originally the Cyrix MediaGX from National Semiconductor to augment its existing line of embedded x86 processor products. During the second quarter of 2004, it launched new low-power Geode NX processors based on the K7 Thoroughbred architecture with speeds of fanless processors 667 MHz and 1 GHz, and 1.4 GHz processor with fan, of TDP 25 W.
AMD's virtualization extension to the 64-bit x86 architecture is named AMD Virtualization, also known by the abbreviation AMD-V, and is sometimes referred to by the code name "Pacifica". AMD processors using Socket AM2, Socket S1, and Socket F include AMD Virtualization support. AMD Virtualization is also supported by release two (8200, 2200 and 1200 series) of the Opteron processors.
AMD also endorsed the development of I/O virtualization technology, curretnly the "AMD I/O Virtualzation Technology" (also known as IOMMU) specification published using HyperTransport architecture by AMD had updated to version 1.2 [11], which the first specification was published prior to Intel
Intel
Core 2 is an eighth-generation x86 architecture microprocessor produced by Intel and based on the Intel Core microarchitecture. Core 2 was to mark the retirement of Intel's Pentium brand name that had been used since 1993, Core 2 saw the reunion of Intel's notebook and desktop product lines, which had diverged with the Pentium M and Pentium 4 in 2003.
The first wave of Core 2 processors was officially released on July 27, 2006. Like the Intel Core brand that it supersedes, Intel currently offers the Core 2 series processor in Duo (two-core), Quad (four-core), and Extreme (two- or four-core with extra cache and higher speed) models. The base processors are code-named "Conroe" (for desktop use) and "Merom" (for portable use); their variants have code names such as "Kentsfield" (quad-core Conroe) and "Penryn" (45 nm Merom). Although the "Woodcrest" server CPUs are also based on Core microarchitecture, they are marketed under the Xeon brand rather than Core 2.[1] As of December 2006, all Core 2 Duo processors are fabricated on 300 mm wafers in Fab 12 in Arizona in the US and Fab 24-2 in County Kildare in Ireland.[citation needed] The 65 nm manufacturing process was developed at Intel's Oregon D1D facility.[citation needed]
Unlike NetBurst-based processors, such as the Pentium 4 and Pentium D, Core 2 does not stress designs based on extremely high clock speeds but rather improvements in the processor's usage of both available clock cycles and power. This translates into more efficient decoding stages, execution units, caches, and buses, as well as many other factors. The CPU-family may also have more than one core on a single chip. The power consumption of these processors is much lower than the Pentium desktop line of products. With a TDP of only 65 W, Core 2 features a significantly reduced power consumption compared to its predecessor desktop chip, the Pentium 4 Prescott with a TDP of 130 W.[citation needed]
Intel Core 2 processors feature Intel 64, Virtualization Technology (except T5500 or lower and E4x00), Execute Disable Bit, and SSE3. Core 2 also introduced SSSE3, LaGrande Technology[citation needed], Enhanced SpeedStep Technology, and Active Management Technology (iAMT2).
