The XFX HD 4890 graphics adapter is based on the advanced TeraScale architecture. ATI announced this model on 02.04.2009. At the core of the card is a chip created with modern lithography. The die houses 1.0 billion transistorsistors transistors, and its area is 282 mm². The core configuration includes 800 shader units, 0 RT Cores for ray tracing, and 0 Tensor Cores for AI tasks. The GDDR5 video memory capacity is 1 GB. Thanks to the 256 bit-bit bus, bandwidth reaches 124.80 GB/s, eliminating delays when working with demanding textures. The GPU's base clock speed is 850 MHz, and in Boost mode, it can automatically increase up to 0 MHz. The TDP level for this model is 190 W, so for a build, it\'s advisable to choose quality cooling and a power supply unit of at least 450 W.
