BlueSmoke posted a review on the AMD Sempron 3400+ CPU
AMD admittedly caught us a little off-guard when they launched the Sempron 3400+. Like most enthusiasts, we were keeping our eye on the higher end of microprocessor development, principally the migration to multiple cores such as in the Athlon64 X2, Xbox 360 and PS3.AMD Sempron 3400+ Review
To be fair, there hasn't been all that much activity since the inception of the Sempron line in June 2004, which was segmented into Socket A and Socket 754 products. The Socket A variants are based on the older K7 architecture, topping out at 3000+ and have faded into relative obsolescence.
