Sapphire HD 7970 Vapor-X is a powerful solution from AMD based on the GCN 1.0 architecture, released on 22.06.2012. The graphics processor is manufactured using a modern process. The 352 mm² die contains approximately 4.3 billion transistorsistors transistors. For graphics processing, 2048 shader units are provided. The technological equipment is complemented by 0 RT Cores and 0 Tensor Cores. The graphics card is equipped with 3 GB of GDDR5 memory. A 384 bit-bit bus is used, providing bandwidth at 288.00 GB/s. The GPU's base clock speed is 1000 MHz, and in Boost mode, it can automatically increase up to 1050 MHz. The nominal thermal design power is 300 W. For stable system operation, a PSU of 700 W or more will be required.
