New revision of the box, that essentially stayed the same with the exception of part number / model / serial number labels. The box itself doesn't have any information, that identifies included Athlon II CPU, and all CPU-specific information is now on the seal. The seal has the following: UPC code, AMD hologram, model number, brief specifications, box part number, and processor's serial number.

One of the best bang for buck!

I purchased this processor for my gaming system on a tight budget. It was only $99 but performs like it cost WAY more! The lack of an L3 cache (compared to the identical Phenom II line with the L3 being the only difference) really doesn't compromise the performance very much at all, I wouldn't even notice it in daily use. As for gaming, I couldn't be happier for only $99!

Not best choice

The processor sole core performance is dispointed than core i3 2100.It's obvious when I use the CPU-Z.
