"The Sapphire Radeon HD 4650 512MB OC follows AMD's reference design for this graphics card, but the clock and memory frequencies are what separate this model from its competitors. The reference core and memory clock is 600MHz and 500MHz, respectively, but Sapphire Technology has this overclocked edition set to run at 650MHz for its RV730PRO core and 900MHz for the GDDR3 memory. The RV730PRO GPU shares similar features to other RV7XX GPUs in that it's built upon a 55nm process, supports UVD2, offers PowerPlay support, and is DirectX 10.1 / OpenGL 2.1 capable. The heatsink fan solution on this graphics card is small, only occupies a single slot, and doesn't cool the video memory, but it does get the job done."
