The Zalman HD 7850 VF1500 graphics adapter is based on the advanced GCN 1.0 architecture. AMD announced this model on 05.03.2012. At the core of the card is a chip created with modern lithography. The die houses 2.8 billion transistorsistors transistors, and its area is 212 mm². The core configuration includes 1024 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The GDDR5 video memory capacity is 2 GB. Thanks to the 256 bit-bit bus, bandwidth reaches 153.60 GB/s, eliminating delays when working with demanding textures. The GPU's base clock speed is 860 MHz, and in Boost mode, it can automatically increase up to 0 MHz. The card's power consumption (TDP) is stated at 130 W. The manufacturer recommends using a power supply unit with a wattage of at least 300 W.
