Starting with RV635, AMD has decided that instead of having separate Pro and XT cards like it did in the Radeon HD 2600 series, it would stick with just one model name in the Radeon HD 3650 series. AMD’s Iain McNaughton explained that the company looked at the mainstream segment and asked itself “what can we do that is different and disruptive to our competitors, while offering more value to our customers?”

Despite only offering one model name, there are still two products that fit under this name – both share the same engine clock, which is set at 725MHz (slower than the Radeon HD 2600 XT’s engine clock), and the same number of stream processors as the Radeon HD 2600 series cards (120 stream processors or 24 five-way superscalar shader units) – both also feature a 128-bit memory interface.
