The HIS HD 4890 Fan Turbo+ (TeraScale) model joined the ATI lineup of graphics accelerators on 02.04.2009. The graphics processor is manufactured using a modern process. The 282 mm² die contains approximately 1.0 billion transistorsistors transistors. The core configuration includes 800 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 256 bit-bit bus is used, providing bandwidth at 124.80 GB/s. 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.
