Radeon HD 3600 Details Leaked
While the current RV670 chips are selling like hotcakes, AMD is working on putting out mid-range and low-end parts for those market segments. The successor to the HD 2600 series, according to graphics card manufacturers, will be called the HD 3600 series (big surprise). The 3600 series will come in two versions, an XT model and a Pro model. The XT will be clocked at 800MHz, and the Pro will be clocked at 600MHz. Both will be attached to 128-bit VRAM, which will run at an unknown clock speed. The Pro will have GDDR2, while the XT will have GDDR3. Both will support DirectX10.1, and the micro-architecture itself is codenamed "RV635". The RV635 should be launched with the RV620, the successor to the HD 2400 series. The RV620 should be dubbed the HD 3400 series.
