XFX HD 7770 Ultra Overclock is a powerful solution from AMD based on the GCN 1.0 architecture, released on 15.02.2012. Thanks to modern manufacturing technology, engineers managed to place 1.5 billion transistorsistors transistors on a 123 mm² die. The core configuration includes 640 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The graphics card is equipped with 1 GB of GDDR5 memory. A 128 bit-bit bus is used, providing bandwidth at 72.00 GB/s. The graphics chip operates at a base clock of 1000 MHz with dynamic acceleration capability up to 0 MHz. The TDP level for this model is 80 W, so for a build, it\'s advisable to choose quality cooling and a power supply unit of at least 250 W.
