Is there a large difference between the AMD 64 X2 4400 and AMD 64 X2 4800?

Question

Here's the 4800: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103778

Here's the 4400: http://www.newegg.com/Product/Product.aspx?Item=N82E16819103776

Both seem to be high quality processors, especially how I'm jumping from a AMD Athlon 64 3200 to that, I think it will upgrade a lot. My question is, is there really a big difference, because the 4800 is 20 dollars more, but the specs look kinda the same.

Can someone explain to me the difference? (and how much)

Answer 1

Does help having a little extra if you need it.

Answer 2

Slight difference in synthetic benchmarks and Super Pi. No noticeable difference in web surfing, downloading, office applications, MP3 and DVD playing.

Most enthusiasts would just overclock the 4400+ to 4800+ level or higher. The Brisbane core could overclock to 3.0Ghz. A 200Mhz overclock is like a walk in the park w/ most retail motherboards. Overclocking is safe if you stay within stock voltage and provide ample cooling. And here's a great way to watch those temps:

Answer 3

.2 GHz

Doesn't look like much of a difference too me.

Floating point applications would show some difference, but very little.

Games would show no difference.
