Just last week, we posted an evaluation of a Radeon HD 3650 card by Diamond Multimedia, where said manufacturer decided to one-up ATI’s reference specifications by raising the amount of on-board memory to a full one gigabyte.  The results, unfortunately, were not overly favorable as the memory happened to be of the inexpensive, low-speed DDR2 variety.Today, however, we take a look at two more HD 3650s, one each from ASUS and HIS, where the emphasis was placed more on clock speeds than on memory buffer size.
