Today Sapphire Technology released two new cards in the 4890 series based on the same architecture as the HD 4870 series, but with higher clock speeds and increased performance. The HD 4890 cards uses the 55nm R790 core offering 800 stream processor units, 256-bit GDDR5 memory interface and an integral hardware video decoder. Improvements include better memory management architecture and lower power requirements at idle while allowing higher clock speeds. The standard HD 4890 model from Sapphire has 850MHz core clock speed with the memory clocked at 975MHz. Sapphire's second offering is the HD 4890 OC Edition with enhanced clock speeds of 901MHz for the core and 1000MHz memory which places this card as the fastest single GPU ATI-based card out there. Both models feature a 1GB frame buffer. The Sapphire 4890 cards are PCI-Express 2, of course, with CrossFireX support and the latest ATI Avivo technology for better video output along with an enhanced hardware Unified Video decoder for Blu-ray and HD DVD content using VC-1 and H.264 codecs. The cards also sport dual-link DVI outputs, and TV-Out and a dedicated HDMI adaptor. The cards are expected to retail around $249US and Sapphire announced it would also be announcing additional cards in the 4890 in the coming weeks. OCC has a review of the Sapphire HD 4890 here.
