AMD Athlon X2 3800+: CU vs CZ

I've been looking around Newegg for a cheap dual-core AMD CPU and have found the AMD Athlon X2 3800+ CPU. I want to get the 65w version for the lower power consumption (overclocking isn't a concern, I keep things stock), but I've hit a bit of a snag. I've found two CPU's that seem identical except for their Model Number:

CPU 1 is here: http://www.newegg.com/Product/Produ...N82E16819103733
It has a model number of ADO3800CUBOX.

CPU 2 is here: http://www.newegg.com/Product/Produ...N82E16819103068
Its model number is ADO3800CZBOX.

I went back and forth over their specs, and they seem identical. I did a bit more digging and came across a CPU fabrication guide for AMD CPU's (http://fab51.com/cpu/guide/opn-64-e.html); the guide says that the CU CPU's only have a L2 Cache of 512k x 2, where as the CZ's have a L2 Cache of 1M x 2. According to Newegg, both CPU's have L2's of 512k x 2.

What's the difference between these two CPU's? Are they identical? Is the CZ CPU on Newegg better than its listed specs?

Wouldn't be the first time slightly-incorrect specs were listed on Newegg. I'd assume the model number is correct over the spec listing.
