Balanced performance and price
Today Advanced Micro Devices (AMD) has officially announced the launch of new graphics accelerator AMD Radeon HD 6790 with excellent performance/price ratio. So, why settle for less?
Among AMD solutions, the card takes its niche between HD 6800 series cards and HD 6700 products (re-branded ATI HD 5700). The main role for HD 6790 is to stand against NVIDIA products, particularly GeForce GTX 550 Ti.
The heart of the novelty, GPU, is a 40nm chip based on Barts LE architecture featuring 40 Texture units (TMU) and 16 Raster processors (ROP). In theory, this provides compute power of up-to 1.34 TFLOPS. HD 6790 equipped with is 1GB of on-board GDDR5 memory connected via 256-interfaces that numbers to 134.4 GB/s of memory throughput. The core runs at 840 Mhz while memory is clocked at 1050 MHz (4200QDR). Regarding the outlook of the card, its design includes black PCB and dual-slot active cooling system.
Apart from standard PCI Express 2.1 x16 the card has one CrosfireX header for multi-card setups. As TDP level of teh novelty does not exceed 150W at full load, it requires two only6-pin power connectors, however, there are HD 6790 versions,with only one additional power connector. In Idle the card consumes about 19Watts. The PCI bracket has pretty much the same set of output connectors HD 6800 and HD 6900 reference solutions have — Dual DVI link, HDMI 1.4a and a pair of Mini DisplayPort 1.2.
The graphics card is compatible with DirectX 11 APi, Shader Model 5.0, and supports multichannel 7.1 HD Surround Sound, as well as other technologies like AMD HD3D, AMD Eyefinity Multi-display and AMD CrossFireX Multi-GPU.
According to AMD’s internal test results gathered from dozen of popular games and benchmarks, the novelty outperforms its main “Green” rival by up-to 30% depending on application. However, you can always check if that statement is true by reading reviews from independent testers.
In the end, the manufacturer suggested retail price for AMD Radeon HD 6790 graphics card is $149.99.
