AMD Single Core
As it appears, we are seeing some sort of activity in AMD's single core lineup. It's nothing really significant, but there are some price fluctuations, roughly $6.00 up or down. One of the most commonly purchased processors in the lower-end of AMD's single core series is the Athlon 64 3200+ Venice [RTPE: ADA3200BPBOX] going for about $160.
We don't suggest you go for one of the high-end options of AMD's single core processors because price-wise, they are very close to the X2 lineup. The highest we would suggest to go with would probably be the AMD Athlon 64 3700+ 1MB San Diego [RTPE: ADA3700BNBOX] going for about $210. If you're planning on spending about $100 more, the X2 processors are what you will want to consider.
For something at about midway in the socket 754 lineup, the AMD Athlon 64 3000+ 512KB Newcastle [RTPE: ADA3000AXBOX] is on sale for about $120. If you're into the mobile processors, the Athlon 64 DTR 3000+ 1MB Hammer [RTPE: AMA3000BEX5AR] is a great buy at $117.
If you're an AMD fan, their Sempron lineup is a great alternative to Intel's Celeron processors. Both are excellent for their price and do as would be expected. For a low budget based build, something along the lines of the Sempron 64 (754) 2500+ 256KB Palermo [RPTE: SDA2500BXBOX] appears to be a great deal at just under $70. Save your $5 and go with the 2500+ rather than the 2800+ as there is only a 200MHz clock speed difference. You can easily overclock your 2500+ those extra 200MHz to reach the 2800+ speeds.
We can see the AMD Turion MT-30 1MB [RTPE: TMSMT30BQX5LD] is at a decent price of about $160. Most of the other prices of the Turion processors haven't changed much, but we are seeing a slight decrease of about $9.00 with the AMD Turion MT-28 512KB [RTPE: TMSMT28BQX4LD] going for a grand total of about $180 shipped.
