TYAN today announced at SC’08 that its current line of 23 AMD Opteron™ processor-based platforms and 1 new AMD Opteron™- processor based product will support the new Quad-Core AMD Opteron™ processor (codenamed “Shanghai”). TYAN launched the TYAN S4992 motherboard that will target high-end HPC and workstation users supporting HyperTransport™ 3.0 technology or 5.2 GT/s HyperTransport™ technology links between the four CPUs. The S4992 will have a total memory capacity of 256GB DDR2 800/667/533/400 ECC memory, (5) PCI Express Gen. 2 slots, (1) PCI-X 64-bit 133MHz slot, (2) GbE ports, and onboard iKVM features. Expected to be in mass production in Q1 of 2009.
VR-Zone took a quick look at the 3-slot self-designed monster card, the Revolution 700 Deluxe featuring HD 4870 X2 GPUs with 2GB of GDDR5 memories. The card comes pre-overclocked at 750MHz core and 1.9GHz memory. We checked out the performance of the card on an overclocked Core i7 920 platform using 3DMark Vantage, Crysis Warhead and Far Cry 2.
TUL announces a brand new graphics card for overclockers – PowerColor Liquid Cooling Solution, LCS HD4870. It has a full water block mounting on the card, fully covering memory and power regulator chip. PowerColor package includes high-flow 3/8" and 1/2" fittings (barbs) to maximize water flow with captured o-rings to prevent leakage. PowerColor LCS HD4870 allows overclockers to maximize core and memory speed to 800MHz and 950MHz (3.8Gbps). The retail price of LCS HD4870 is USD$369.
Sapphire today announced next-generation AMD FireStream 9250™ processor accelerates scientific and engineering calculations, efficiently delivering supercomputer performance at up to eight gigaflops-per-watt. It features 1GB of GDDR3 memory. The FireStream™ 9250 and the supporting SDK are available in beginning of November 2008 while AMD FireStream™ 9170 is currently available for purchase now.
VR-Zone took a sneak peek at the upcoming Radeon HD 4830 card from MSI. We have already told you that this card has 640 SPs and run on 256-bit memory interface. MSI Radeon HD 4830 card is clocked at 575MHz core and 1800MHz memory. This card has 8 Samsung K4J52324QH-HJ1A GDDR3 memory chips rated at 1ns totally 512MB and you would need a 6-pin PCIe power for this card. The launch date is pushed back 2 days to 23rd October and it is expected to be priced lower than US$150.
