Confusing products codes

Hello,

What dfferences exist between these products:

SDCZ80-064G-X46

and

SDCZ80-064G-G46

The first one can be found here: http://www.computeruniverse.net/en/products/90533399/sandisk-cruzer-extreme-pro-usb3-0.asp#data

The second here: http://www.computeruniverse.net/en/products/90465504/sandisk-cruzer-extreme-usb3-0.asp#data

If I compare these products in that online store, the only difference is the price (9 EUR).

Maybe there are more differences?

In SanDisk site, the first product, SDCZ80-064G-X46 doesn’t appear now.

Thanks!

By the way, I also can’t seem to spot the difference. Throughput speed perhaps? 

Someone says on Amazon.com that SDCZ80-064G-X46 it’s an older revision.

SDCZ80-064G-G46 it’s newer and I have it right now.

the products are the same. the last 3 of the SKU are the packaging code for distribution channels that determine what languages are on the packaging.
