some time ago. The triple-core processor still see the same specifications for quad-core variants, the naming of the processor lineup, according to the AMD branding scheme, will be named as Phenom triple-core 8000 series, the processor line will be focused on what AMD called the fourth market segment or the "High-end Mainstream" segment beside Value, Mainstream and Performance segments in an interview with BetaNews, which the targeted customers of the processors are "those who are willing to pay more for more performance but not required for too much processing power as required by gamers and system builders", while there are single core (Sempron) variants for low-end market, and dual-core (Athlon) variants for mid-range market, and quad-core (Phenom quad-core 9000 series and Phenom FX) variants should be seen in the high-end market at the same time frame. Further in 2008, AMD will introduce Deneb FX for the replacement for the AMD Quad FX platform, as well as Deneb for the mainstream. Propos and Regor will also replace Kuma and Rana in the lower market segments. Socket AM2+ being named in the late 2006 might actually have been the original AM3 socket, but as naming conventions changed, so that the next generation of consumer desktop socket capable of DDR3 will be socket AM3.--> Features Fabrication technology AMD has introduced the microprocessors manufactured at 65 nm feature width using Silicon-on-insulator (SOI) technology, since the release of K10 coincides with the volume ramp of this manufacturing process. Supported DRAM standards The K8 family was known to be particularly sensitive to memory latency since its design gains performance by minimizing this through the use of an on-die memory controller (integrated into the CPU); increased latency in the external modules negates the usefulness of the feature. DDR2 RAM introduces some additional latency over DDR RAM since the DRAM is internally driven by a clock at one quarter of the external data frequency, as opposed to one half that of DDR. However, since the command clock rate in DDR2 is doubled relative to DDR and other latency-reducing features (e.g. additive latency) have been introduced, common comparisons based on CAS latency alone are not sufficient. For example, Socket AM2 processors are known to demonstrate similar performance using DDR2 SDRAM as Socket 939 processors that utilize DDR-400 SDRAM. K10 processors support DDR2 SDRAM rated up to DDR2-1066 (1066 MHz). While some desktop K10 processors are AM2+ supporting only DDR2,
