Thread: AMD Athlon X2 550 Black Edition

AMD recently introduced new dual-core processors for two, namely the AMD Athlon X2 550 Black Edition and AMD Athlon X2 250th. At this time we had but no Phenom X2 550 Black Edition is available. The Phenom X2 550 is the new flagship of AMD's dual-core processors. It is the Phenom fire and all that is involved. Specifically, compared to the Athlon X2 is a L3 cache and the fact that CPUs with freely adjustable multipliers can acquire some of these. For this is the abbreviation, "Black Edition" and is aimed at enthusiasts and overclockers from.

AMD Socket A time had two processors families while in the offer. The powerful, more expensive Athlon XP and the weaker, but cost Duron. They differed mainly by the size of the L2 cache and clock speeds. It is this principle seems AMD now take up again - only are the brands today, Athlon X2 and Athlon X2. Unlike the Athlon X2 ("Regor") is the Athlon X2 ("Callisto") but no native dual-core, but is the Phenom X4 (Deneb) Quad-core from. Up to two cores disabled X4 then, are the architectures and cache levels of Phenom 550 and Phenom X2 X3 or absolutely identical.



It turned for us is the question, of whether the L3 cache is so vital that the name "Phenom II" can be justified. One thing is certain: the Phenom X2 550 must be clear to the Athlon X2 II 250 can issue than by the clock difference of 100 MHz. he Athlon X2 550 is a derivative of the quad-core and differs technically not really the same. The die area is therefore 258 mm ² in 45 nm and contains roughly 758 million transistors. They are exactly the same values on the example, a Phenom X4 955 also comes. Thus specification features also read the other very identical: 128 KB L1 cache per core total, 64 KB for data and 64 KB for instructions exactly to its core. Just 512 KB L2 cache per. The amount of L1 and L2 cache is thus the same as a quad-core, by twice the number of cores on twice the number of cache is, however, considering the CPU as a whole.

First designed by AMD Athlon 64 X2 dual-core desktop CPU's. This native dual-core from scratch as an already multi - Athlon 64 active CPU using a die with one core and functional involvement, and a shared dual channel memory controller through two connecting / Made by North Bridge and additional control logic.

AMD Althlon X2 550 have a unique features like powerful, more expensive Athlon XP and the weaker, but cost Duron. They differed mainly by the size of the L2 cache and clock speeds.
