The Sapphire HD 7950 Mac Edition graphics card from AMD is built on the GCN 1.0 architecture and was officially introduced on 07.03.2013. The graphics processor is manufactured using a modern process. The 352 mm² die contains approximately 4.3 billion transistorsistors transistors. The model's computational arsenal includes 1792 universal processors. Also available are 0 specialized cores for ray rendering and 0 cores for accelerating artificial intelligence. The GDDR5 video memory capacity is 3 GB. Thanks to the 384 bit-bit bus, bandwidth reaches 240.00 GB/s, eliminating delays when working with demanding textures. The GPU's base clock speed is 800 MHz, and in Boost mode, it can automatically increase up to 0 MHz. The TDP level for this model is 200 W, so for a build, it\'s advisable to choose quality cooling and a power supply unit of at least 550 W.
