AMD 7000 series

The new CPUs are part of the Athlon X2 product family, but carry a new 7000-series number sequence. The 7750 and 7550 (available to OEMs only) depart from the old 65 nm (K8) Brisbane core and use the “Kuma” core, which is based on the K10 or Stars architecture (the K10 name does not officially exist, according to AMD.) Built in 65 nm, the chips are released more than half a year after their initially planned release and offer clock speeds of 2.5 and 2.7 GHz. Like the preceding Brisbane core, Kuma comes with 128 KB L1 data cache, 128 KB L1 instruction cache and 1 MB L2 cache. However, Kuma adds 2 MB L3 cache – Brisbane CPUs do not integrate L3 cache.


The Athlon X2 7750 is currently listed with a tray-price of $79, just above the $76 the company charges for its Athlon X2 6000. With a quick look over to Intel, the same $79 would not be enough to buy you a Core 2 Duo-class processor. Intel currently sells the Pentium Dual-Core E2220 (2.4 GHz, 65 nm) for $74 and the E5200 (2.5 GHz, 45 nm) for $84. The cheapest Core 2 Duo, the E7200, lists for $113.
