AMD Processor upgrade: AMD Athlon 64 X2 4400+ 2.2 GHz Socket 939 L2 cache - 2 MB ( 1 MB per core )

The Athlon 64 has been around since [date] and was the first processor with 64-bit instructions to hit the consumer market. It's still around, and it's now available for Socket AM2 motherboards. AMD has released the 3800+, the 3500+ (in two different

When AMD brought out its dual-core version of the Athlon 64 in June 2005, it dominated Intel's equivalent offerings of the time, the dual-core Pentium D and the single-core Pentium 4 CPUs . To this day, the Athlon 64 X2 uses the same K8 microarchitec

Still A Great Processor

This processor makes the job of running several programs at once easier to deal with than what I was used to with previous processors. The 2mb cache helps with that so don't settle for the 4200+. Gaming has been better, clearer, and more stable, but there still could be room for improvement....

Athlon 64 X2 4400+

With this processor installed, my system never slows down. As a side benefit, it runs cool and doesn't consume much power. Even the stock cooler keeps it under 50 degrees load, which is impressive. For those wondering whether dual core is worth the upgrade, the answer is "it depends." If you...

Smokes all others!

I run an app that has dual processor support and this thing screams and is rock solid with the OCZ platinum ram it's running with. I don't know how to overclock but this processor is supposed to run supremely when overclocked slightly and might even match the performance of the 4800 x2 when...

Fast and efficient

I use this with an Asus A8N SLI premium motherboard. Have not had ANY problems. I am not an experienced computer builder, but I had absolutely no troubles constructing the computer around this processor. I used some type of Arctic Silver as a compound and did not experience heat issues (although...

Stepping Up from Intel P4 2.4GHz

Stepping up from an old Intel 2.4GHz P4, the Athlon X2 4400+ is a delight. I run several apps at a time and the multitasking performance of this CPU is exceptional. It simply plows through them. Whether I'm streaming audio to a wireless Squeezebox, downloading new Podcasts, playing TV shows,...

Maybe in a year it will be better.....

I've had this chip since November, and I've tried to give both AMD and Nvidia time to fix the bugs, but I'm just sick of all my games crashing, running choppily, and having weird speed ups during gameplay. I've tried every fix on internet forums that are supposed to help my problems, and still...
