Sapphire exhibits first Radeon HD 7790 graphics card
AMD’s long term graphics card partner Sapphire has showed the company’s first Radeon HD 7790 Dual-X graphics card.
The new product is based on a 21.5 cm long PCB and cooling designed by Sapphire and includes an aluminum fin-stack heatsink cooled by two 80 mm fans. The card has two DVI connectors as well as HDMI and DisplayPort and draws power from a single 6-pin PCI-E power connector.
Supposedly the card’s GPU runs at 1075 MHz, while the memory operates at full 6400 MHz but these details were taken from a GPU-Z screenshot and may be inaccurate. Stream processor number, memory bus width and other specs were not reported as GPU-Z still does not support the Bonaire GPU the Radeon HD 7790 is based on.
The first test results are promising – in 3DMark Fire Strike the HD 7790 scored 4026 points which is just 8.3 per cent slower than the HD 7850, which scored 4395 points. In 3DMark 2011 the HD 7790 managed to achieve 1583 points while the HD 7850 got 1734 points leaving the HD 7790 8.7 per cent behind.
Pricing of the Sapphire HD 7790 Dual-X graphics card is still unknown.
