Die size of RV620 is about 66.5mm^2, while RV610 die size is 78.75mm^2. So it is about 15% smaller. Their PCB is the same, all 24*24mm^2.

From the charts we can see, HD 3450 and HD 3470’s main difference is only their core/memory frequency. The core frequency of HD 3470 is 33.3% higher than HD 3450.
The card in our hand is RV620 LE, Radeon HD 3450 with 128MB GDDR2 memory. For NDA reason, we can not post any picture before the official launch.

It is an ES, so it have power-sucking issues. The final retail version may fix the problem
