SAPPHIRE Technology has introduced a new series of affordable graphics cards, based on AMD’s new graphics GCN (Graphics Core Next) architecture. The new SAPPHIRE HD 7700 series is a new family of graphics cards targeting the enthusiast on a budget and mainstream users looking for increased graphics performance without breaking the bank. It is based on the second family of GPU’s from AMD built in its new 28nm process and featuring the GCN graphics processing architecture. The new HD 7770 and HD 7750 GPUs have an optimised internal structure sharing many of the features of the high performance HD 7900 series already released, but with fewer Stream processors and a simplified 128-bit high speed memory interface. Pricing details in India aren’t fixed, yet, but we’ll update you as soon as we get them.
The HD 7770
Two models of the HD 7770 are being introduced by SAPPHIRE at launch. The SAPPHIRE HD 7770 will ship with a core clock speed of 1GHz, and will be known as the SAPPHIRE HD 7770 “GHz Edition”. It is equipped with 1GB of DDR5 memory clocked at 1125MHz (4.5 Gb/s effective). At the same time, SAPPHIRE is introducing a high performance model, the SAPPHIRE HD 7770 GHz OC Edition, which is factory overclocked to 1150 MHz core and 1250MHz memory (5Gb/s effective). Both models have a SAPPHIRE original single fan heatpipe cooler. For the more budget conscious, the third model in the series is the SAPPHIRE HD 7750, which shares all the features of the HD 7770 version, except that it ships with the lower core clocks of 800MHz and different output configuration as well as a lower Stream processor count. It has 1GB of memory clocked at 1125MHz (4.5 GB/s effective), and a single fan heatpipe cooler.
The HD 7750
SAPPHIRE will also be bundling an overclocking tool, TriXX, which allows the tuning of GPU voltage as well as core and memory clocks, whilst continuously displaying temperature. Manual control of fan speed is supported, as well as user created fan profiles and the ability to save up to four different performance settings. The HD 7000 series is the third generation of DirectX 11 compatible solutions from the graphics division of AMD. The new SAPPHIRE HD 7700 series has support 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. It also supports PCI-Express Gen3.0 interface and Eyefinity, now in its second generation. With Dual-link DVI, HDMI and two mini-DisplayPort outputs, the HD 7770 models can support configurations of up to 6 monitors. The HD 7750 has Dual link DVI, HDMI and a single DisplayPort output, supporting upto four monitors. Expect to see these cards in your hardware stores, soon.
