AMD Officially Introduces Radeon HD 7790 Graphics Card

An official introduction of a new graphics card from AMD, entitled Radeon HD 7790, has been settled into a dedicated press briefing. Within the framework of this briefing, the company not only gave a detailed description of a long-awaited product but also divulged a comparative performance analysis with its main rival’s adapter – Nvidia GeForce GTX 650 Ti. Therefore, AMD Radeon HD 7790 graphics card belongs to mainstream items and is targeting a wide range of customers. It is based on AMD Bonaire GPU with AMD GCN architecture developed under 28 nm technological process. The GPU consists of 896 current processors, 14 computing blocks, 56 texture blocks, and 16 ROP blocks.

Video memory subsystem comprises 1 GB of GDDR5 memory type, employing 128-bit bus. Its nominal clock frequency equals to 1500 MHz, while effective frequency makes up 6000 MHz. The overall efficiency level of this adapter is estimated at 1.79 TFLOPS; this index is twice larger than the one recorded with AMD Radeon HD 7750 series.

To continue, AMD Radeon HD 7790 is thought to support an improved AMD PowerTune technology that takes responsibility for a dynamic voltage switch and clock frequency alteration. An improved version stipulates the availability of twice as much number of operational modes which provide for the achievement of the most optimal GPU functional. The process of modes switching is realized within 10 ms; at the same time, mode algorithm runs on the basis of a current loading level, TDP level, as well as TDC level.

With regard to the efficiency level claimed for a new graphics adapter from AMD, it should be noted that it proves to demonstrate a stable advantage over GeForce GTX 650 Ti model from Nvidia in synthetic and gaming benchmarks. In addition, Radeon HD 7790 demonstrates an appropriate index of scalar values on the combination of two items in CrossFire configuration. This allows gamers to receive fluent imaging with a more accurate detailed elaboration.
