SAPPHIRE Technology has just introduced a passively cooled card in its new HD 7700 series – the SAPPHIRE HD 7750 ULTIMATE is the first totally silent card to embody all the features of this new generation of products based on the revolutionary new graphics GCN (Graphics Core Next) architecture from AMD.
The SAPPHIRE HD 7750 ULTIMATE is the first card in this generation to use a passive heatpipe and heatsink cooler to deliver totally silent cooling, and increased reliability as it has no mechanical moving parts. It shares all the features of the HD 7700 series and the highly acclaimed GCN graphics processing architecture making it ideal for HTPCs and any general purpose PC where operational noise needs to be kept to a minimum.
The SAPPHIRE HD 7750 ULTIMATE delivers excellent performance with core clocks of 800 MHz and 1 GB of DDR5 memory clocked at 1125 MHz (4.5 GB/s effective). It is believed to be the fastest passively cooled 128-bit graphics card on the market.
HDMI specifications have also increased in the HD 7000 series. Fast HDMI 1.4a supports Stereoscopic 3D with enhanced frame rates of 60 Hz per eye – 120Hz total. It is also ready for the next generation of 4K displays that can be driven from a single high speed input of 3GHz HDMI 1.4a or DisplayPort 1.2 HBR2.
APP Acceleration is the name given to the enhanced performance of a wide range of applications using the stream processing capabilities and specific hardware features of the graphics architecture. The HD 7000 series has been optimised for this type of task. Typical applications include Video encoding and decoding, compression and multiplexing for media distribution, gaming or video conferencing. APP acceleration can also enhance everyday tasks such as Internet browsing, Office applications and file compression with supported software suites.
Working or gaming with multiple monitors is becoming increasingly popular, and the SAPPHIRE HD 7700 series supports this with AMD Eyefinity, now in its second generation. The SAPPHIRE HD 7750 ULTIMATE has Dual link DVI, HDMI and a single DisplayPort output, supporting up to four monitors. In addition, the SAPPHIRE HD 7700 series cards can simultaneously output multiple, independent audio streams allowing the correct audio content to be associated with different applications on different screens.
The HD 7000 series is the third generation of DirectX 11 compatible solutions from the graphics division of AMD – formerly ATI. The new SAPPHIRE HD 7700 series is ready for DirectX 11.1 and the new Windows 8 operating system as well as delivering all the features of the current DirectX 11 such as DirectCompute11 and multi threaded communications with the CPU. Communication with the host PC is optimised with the implementation of the latest high speed PCI-Express Gen3.0 interface, and multiple cards can be used to further enhance performance in CrossFireX mode on a suitably specified mainboard.
