Rectron has launched a new budget-priced PC graphics card range that caters not only for high‑definition home theatre entertainment using Blu-ray DVD discs and other HD sources, but also for the latest gaming technologies based on DirectX 11 and Windows 7.

Built on the highly-anticipated ATI Radeon HD 5450 GPU, the new Gigabyte GV‑R545SC‑1GI, with 1 Gbytes of memory, has a suggested retail price of R999, while the GV‑545OC-512I, with 512 Mbytes of memory, has a suggested retail price of R799.
“The Radeon HD 5450 GPU brings DirectX 11 to the masses with great performance at very competitive price points,” says Tony Chiang-Lin, Rectron Components Solutions and Systems Business Manager.
“Featuring HDMI technology for HD graphics output, ATI Crossfire multi-graphics card technology and Microsoft DirectX 11 support, it was developed to provide a good balance of gaming and entertainment performance.”
Besides targeting budget gamers, the new Gigabyte Radeon HD 5450 cards are designed for home theatre enthusiasts, as they use Screen Cooling, a cooling technology ensuring the cards run 100% silent.
“There is the option of a fan for those that prefer active cooling. It features gold-plated HDMI ports for better signal transfer and Ultra Durable 2 Technology to ensure the cards run cooler and last longer thanks to high quality components,” he adds.
“The high-end home theatre functionality of the new Gigabyte Radeon HD 5450 cards is further complemented by their ability to take full advantage of Blu-ray functionality with dual-stream, picture in picture (PIP) capabilities, dynamic contrast and enhanced DVD upscaling.”
The Gigabyte GV-R5450 Series also provide real one-cable HDMI connectivity to TVs and displays with HDMI with up to 2 channel 48 kHz stereo or 7.1 AC3, enabling a plug-and-play cable-less audio solution.
The Gigabyte GV-R545SC-1GI and GV-R545OC-512I also use the latest DDR3 memory architecture, and consume less than 20 watts under full load, making the cards the ideal choice for implementation across a large diverse install base of desktop PCs.
In addition to supporting a wide range of the latest graphics technologies including dual mode software CrossFireX, ATI Stream technology, Microsoft DirectX 11, PCI Express 2.1 and UVD 2, the Gigabyte GV-R5000 series are also equipped with proprietary Gigabyte technologies, including Ultra Durable 2 technology, and native HDMI port for HD gaming and Blu-ray movie playback.
Benefiting from ATI Stream Technology, the Gigabyte GV-R545SC-1GI and GV-R545OC-512I uses the massive parallel processing power of ATI’s latest GPU technology for physics, artificial intelligence, stream computing and ray tracing calculations, and tackle demanding tasks like video transcoding at high speeds.
Additionally, the GV-R545SC-1GI uses Gigabyte’s unique Screen-Cooling thermal design, which takes advantage of the thermal difference between the interior and exterior of the chassis to create a natural convection system to fanlessly cool the GPU without generating unwanted noise.
“The Gigabyte GV-R545SC-1GI was designed to ensure stable cooling without compromising system performance,” says Chiang-Lin.
“Furthermore, the Gigabyte GV-R545SC-1GI and GV-R545OC-512I support for DirectX 11 includes support for Shader Model 5.0, delivering the most life-like 3D gaming effects. Also, both models support the Microsoft Windows 7 operating system which enables users to have a more interactive and efficient GPU-accelerated environment.”
Using Avivo HD video and display technology, the GV-R545SC-1GI and GV-R545OC-512I support Ultra Durable 2 for decoding processing-intensive content for digital output at all resolutions up to 1080p, as well as catering for greater cooling, lower power loss, and longer product life.
Finally, lower RDS (on) MOSFETs have lower power consumption during the switching process, resulting in less heat generated by the GPU. Ferrite core chokes hold energy much longer than common iron-core chokes and lower ESR solid capacitor are more stable and reliable than other cards on the market.
