AMD has juggled the prices of its desktop processors, knocking up to 27.5 per cent of various CPUs, introducing some new, low-power ones, and upping what it charges for a number of other parts.

Among the processors that are now cheaper than before are members of the dual-core Athlon 64 X2 line and the single-core Athlon 64 series. Dual-core prices fell by between 6.2 per cent and 12.4 per cent, while the single-core cuts ranged from 22.4 per cent to 27.5 per cent.

New to AMD's X2 price list are the 'Black Edition' 6400+ and 5000+, the latter a new, $136 part while the former replaced the existing vanilla 6400+. The 4000+ was dropped from the list. So too was the Athlon 64 3200+, but its fellows were joined by the new 2.2GHz LE-1600 and the 2.4GHz LE-1620. Both are 45W parts priced at $47 and $53, respectively.

The 45W Energy Efficient Athlon X2 series gained a new member, the 2.3GHz BE-2400, while the existing members - the 2.1GHz BE-2350 and the 1.9GHz BE-2300 - now cost around six per cent more than before.

And there's a new mobile-oriented Athlon X2: the 1.8GHz TK-55. It's priced at $144, the same as the existing 1.7GHz TK-53.

The former top-of-the-range desktop Sempron, the 2GHz LE-1150, now sits under the 2.2GHz LE-1250 and the 2.1GHz LE-1200, priced at $53 and $48, respectively. The LE-1150's price went up, from $37 to $42, its former price point being taken up by the new 1.9GHz LE-1100.

The prices of old-style Semprons stayed where they were, though the 3200+ was dropped from the list.
