The new product is based on a 40-nanometer Cedar chip, consisting of 292 million transistors. Its structure contains 4 rasterization units, 8 texture units, 80 stream processors and a 64-bit memory controller.
The card's power consumption under load does not exceed 19,1 W. Other trump cards of the HD 5450 are simultaneous image output to three displays, support for DirectX 11, Dolby TrueHD and DTS-HD Master Audio, as well as modest heat dissipation, which allows for a small aluminum radiator on the GPUThe rear panel contains DVI, HDMI and D-Sub interfaces.
To reduce the cost of serial products, AMD recommends installing DDR2/DDR3 RAM chips (not to be confused with GDDR2 and GDDR3) with frequencies of 800 and 1600 MHz, respectively, on graphics adapters of this series. The memory capacity will vary from 512 to 1024 MB.
Gaming performance for the Radeon HD 5450 is of secondary importance. The new product is slightly inferior to the representative of the previous generation HD 4550 and, at the same time, turns out to be stronger than the competing NVIDIA GeForce 210.
