GIGABYTE introduced two new graphics card models over the last week, based on GPUs that have been in existence for a while now. The first is the GV-R645-1GI, a low-profile single-slot graphics card based on the AMD Radeon HD 6450, and the GV-N440-1GI, a cool and quiet full-height double-slot graphics card, based on NVIDIA GeForce GT 440.
The GV-R645-1GI is armed with 1 GB of DDR3 memory over a 64-bit wide memory interface. It features clock speeds of 625 MHz core, with 1100 MHz memory. It uses a tiny, radial-fin fan-heatsink to cool the GPU. Its display outputs include dual-link DVI, HDMI (gold-plated connector), and D-Sub, which is detachable. GIGABYTE tried to pull off a neat marketing trick by mentioning that the card is "PCI-E 3.0 motherboard compatible", something every PCI-Express 2.0 and 1.0 graphics card ever made, already is.
The GV-N440-1GI, on the other hand, is clocked at 810 MHz (core), 1620 MHz (CUDA cores), and 1600 MHz memory. It packs 1 GB of DDR3 memory across a 128-bit wide bus. Its cooling assembly uses a chunky aluminum heatsink with radially-projecting, forked aluminum fins, ventilated by an 80 mm spinner. Outputs include one each of dual-link DVI, HDMI (gold-plated connector), and D-Sub. The GV-R645-1GI will be priced under US $55, while the GV-N440-1GI will be priced under US $90.
