Summary: This is an excellent budget CPU, and if you're short on cash, get a Sempron 64. You'll hardly notice the difference between this and an Athlon 64. My CPU-Z actually reports mine as an Athlon 64, which is odd. Don't let the 256KB of cache scare you away, you probably won't notice it. I can actually compare this with my Athlon 64 day to day usage.
Summary: This has been a really wonderful desktop processor. It runs faster than it looks, and can adequately power a low-range desktop computer. I would recommend this processor to anyone looking to build a new word-processing/ internet surfing PC on a budget.
Summary: This processor is very efficient for many purpose, such as file storage or multimedia center pc. The performance is pretty good too. However I found if I run 24x7, the stock heatsink is loud and does not dissipate heat good enough.
Summary: It's amazing what you can buy for $30 on clearance. This is essentially an Athlon 64 processor with a crippled cache, but at a peanuts price. Amazing speed and flexibility per dollar. Really easy to overclock, even with the stock heatsink (but it can go a lot higher with a good aftermarket model). With both Socket 754 and AGP being phased out, there are great deals out there for matching motherboards and video cards too. You absolutely cannot go wrong.
Pros: 64 bit support; being closed out at outstanding prices; easy to overclock; low core temperature
Cons: Socket 754 does not support dual channel memory; Fan on stock heatsink too noisy
Summary: A very value-priced processor that's great for daily tasks. With a decent motherboard and some decent memory, it can be overclocked to good speeds without any problems. Despite not support dual-channel memory, it still operates nicely without any slowdowns.
Pros: 64-bit support, low power, overclockability
Cons: 256-k L2 cache, original HSF is noisy, no C'n'Q support, single channel memory interface
Summary: This CPU runs perfectly in my "yet another $200 whitebox". Coupled with a low-priced ECS motherboard, 512M RAM, it is powerful enough for light office editing, internet surfing, music and video playing -- so far so satisfied for everyday jobs. The stock fan however is a bit noisy, being much louder than my PNY 4700le video fan, Ultra V-Series power supply fan and a generic 120mm ball bearing system fan. Anyway for the $29.99 price I am more than happy with it.
Pros: Superb performance for the price ($29.99 + shipping at Fry's Outpost); Low voltage and frequency keep the system temprature low
Cons: Noisy stock fan; 256k L2 cache is at most for a decent office computer
Summary: This chip is awesome. It was quite fast at stock speed, but once i overclocked it, it became a beast. With the stock voltage of 1.4v, i got this baby from 1.6 ghz to 2.3ghz. I probably could push it further, but having two sticks of ram limits my computer. With only 1 stick, i have pushed it over 300fsb, which equates to over 2.4 ghz.
Summary: The Sempron 2800+ I received was labeled as a 32-bit but actually turned out to be a 64-bit version:-) I really do understand why AMD and other manufacturers market thing this way so, don't take the title literally. Anyhow this chip overclocks well. Perfect chip for a budget system.
Summary: I bought it for my desktop because I want to set up a server to share my pictures to my friends. And I found Sempron has low price but not bad performance. Besides, it is quiet and less thermal heat. Good for basic usage of computing.
