Hightech Information System Limited launches its HIS 6970 & 6950 Fan Turbo 2GB GDDR5 graphics card. Offering the latest and greatest features like AMD Eyefinity technology,
AMD HD3D technology and DirectX 11 support, the new 6900 Turbo Series provides flawless image quality and unbelievable performance to the gamers at every advantages. The HIS 6950 Turbo has over-clocked its core clock speed to 840MHz and memory clock at 5,120MHz, delivering serious high-definition gaming frame rates.

The HIS 6970 Turbo supplies the same 2GB GDDR5 but at a maximum core clock speed of 900MHz and memory clock of 5,600MHz. The utmost speed will let you enjoy the high resolution and fast frame rates which directly translate into superior performance and ultra-high bandwidth.

Here's the Radeon HD 6990 up close. The HD 6990 is AMD's new dual-GPU graphics card that extends the performance leadership held by Radeon HD 5970. The pictures put rest to some speculation surrounding the cooler design. It now appears that the cooler design is similar to that of the GeForce GTX 295 single-PCB, as far as air-flow is concerned. A single long PCB holds two GPU systems on either sides, a centrally-located blower pushes air on either sides. The exhaust from one GPU is sent out of the case, while that from the other is pushed out of the card from its rear portion.

The Radeon HD 6990 uses two 40 nm Cayman GPUs, it packs a total of 3072 stream processors, and 4096 MB of memory between the two GPU systems. It also features a new kind of display output that consists of one dual-link DVI and four mini-DP 1.2. Power is drawn in from one 6-pin and an 8-pin PCIe connector. The card can pair with another of its kind for 4-GPU CrossFireX. It is expected to be released a little later in this quarter.

A few days earlier, AMD's Matt Skynner displayed the company's newest graphics card that seeks to extend the performance leadership currently held by Radeon HD 5970. The dual-GPU AMD Radeon HD 6990, codenamed "Antilles", makes use of two 40 nm "Cayman" GPU, which powers the single-GPU HD 6950 and HD 6970. The core configuration of Cayman in Antilles is not known. The card itself keeps up with the product styling that all Radeon HD 6000 series carry, it's about as long as the HD 5970.

This time, AMD is toying with a revolutionary new cooler design that makes use of a cylindrical blower (like ones used in air-curtains, on a much smaller scale) to draw air from the rear portion of the cooler, and circulate through the complex vapor-chamber enhanced heatsink inside. In other words, the card lacks a fan intake hole where it's typically located, but the rear portion serves that purpose. Power is drawn in from two 8-pin PCI-E power connectors. AMD is expected to release the new enthusiast graphics card in this quarter.

Club3D announced its latest high-end graphics cards based on AMD's new Radeon HD 6970 and HD 6950 graphics processors (GPUs). Both cards stick to AMD reference board design and clock speeds. The HD 6970 from Club3D carries the model number CGAX-69748, features 1536 advanced stream processors, 2 GB of 5.5 GT/s GDDR5 memory across a 256-bit wide memory interface, with clock speeds of 880 MHz core and 5500 MHz (GDDR5 effective) memory. The HD 6950 (CGAX-69548) features 1408 advanced stream processors, 2 GB of GDDR5 memory, and clock speeds of 800 MHz core and 5000 MHz (GDDR5 effective) memory. Both cards are expected to feature standard pricing.

SAPPHIRE Technology, the largest manufacturer and supplier worldwide of graphics solutions based on AMD technology has just added two new models bringing higher performance and new features to the recently launched HD 6000 series. The new SAPPHIRE HD 6970 uses a new GPU architecture from AMD which features dual graphics engines in one chip with 24 SIMD engines and a total of 1536 stream processors with 96 texture units, providing massively parallel computing power for graphics and other accelerated applications. Its core clock speed of 880MHz, together with a dedicated high speed interface to 2GB of GDDR5 memory running at 1375MHz (5.5Gb/s effective) delivers the highest performance in this series. New Tesselation engines bring up to three times the performance of the previous generation, and new Enhanced Quality AA and filtering modes bring the highest image quality ever achieved.

At last, specifications of AMD's elusive Radeon HD 6970 and Radeon HD 6990 graphics accelerators made it to the internet, with slides exposing details such as stream processor count. The Radeon HD 6970 is based on a new 40 nm GPU by AMD, codenamed "Cayman". The dual-GPU accelerator being designed using two Cayman GPUs is codenamed "Antilles", and carries the product name Radeon HD 6990.

Cayman packs 1920 stream processors, spread across 30 SIMD engines, indicating the 4D stream processor architecture, generating single-precision computational power of 3 TFLOPs. It packs 96 TMUs, 128 Z/Stencil ROPs, and 32 color ROPs. Its memory bandwidth of 160 GB/s indicates that it uses a 256-bit wide GDDR5 memory interface. The memory amount, however, seems to have been doubled to 2 GB on the Radeon HD 6970. Antilles uses two of these Cayman GPUs, combined computational power of 6 TFLOPs, a total of 3840 stream processors, total memory bandwidth of 307.2 GB/s, a total of 4 GB of memory, load and idle board power ratings at 300W and 30W, respectively.

Originally poised for a November 22 launch, and plagued by reported delays, the Radeon HD 6900 series from AMD is indeed staring down at a three-week delay. According to a new release by AMD circulated to press sites, AMD is pinning the new launch date to be "in the week of" December 13, 2010. AMD tried to explain that the Radeon HD 5800 series is still in strong demand, and the Radeon HD 5970 is still maintaining performance leadership, perhaps blaming congestion in inventories for the delay, and not anything to do with manufacturing.

The first part of the explanation is unconvincing. If AMD did not want to disturb Radeon HD 5800 series sales, there wouldn't be Radeon HD 6800 series, which was launched with the idea of giving HD 5800-like performance at more affordable prices. The second part, however, is hard to dispute. AMD signed off its release saying that enthusiasts will find the products worth the wait. December 13, however, could disturb some gifting (or self-gifting) plans for Xmas. Given the swamped courier and logistics services at that time, it will be tough to get a Radeon HD 6900 series product in time for the celebrations.
