Even as NVIDIA is taking its own sweet time to complete building its lineup of DirectX 11 compliant GPUs to target all market segments, AMD, which got a 6 months' headstart into releasing its lineup, which ended up targeting all market segments in a span of 5 months, is readying the Radeon HD 6000 series for launch well within this year. Just as the Radeon HD 5000 series GPU family was codenamed Evergreen with its members codenamed after evergreen trees (such as Cypress, Juniper, Redwood, Cedar), the Radeon HD 6000 is codenamed "Southern Islands", with its members codenamed after islands in the Caribbean (not islands in the Mediterranean).

"Bart" (after Saint Barthélemy island) is the codename for the performance/upper-mid segment GPU, a successor to the "Juniper" Radeon HD 5700 series. "Cayman" (after Cayman Islands) is the enthusiast GPU, successor to Cypress, and will go into making SKUs that succeed the Radeon HD 5800 series. Finally, the king of the hill is codenamed "Antilles" (after Antilles Islands), it is the dual-GPU SKU that makes use of two Cayman GPUs, successor to the Radeon HD 5970 "Hemlock". AMD partners will be in a position to sell graphics cards based on these by November 2010. The Radeon HD 6970 "Antilles" should be out by December 2010. The lower-half of the family will likely release next year.

Club 3D, European market leader for graphics cards, today announced the release of its new 40nm process technology based HD5970 graphics card. Equipped with two ATI Hemlock graphics processing units. The fastest graphics card on the planet has been developed.

Engineered for speed, the Club 3D HD5970 delivers an unrivaled HD gaming experience so you can play the latest, most demanding HD titles like never before. Featuring cutting-edge graphic, display and memory technology, this next-generation powerhouse delivers unprecedented performance straight out of the box. Unlocked, this graphics card has massive headroom, so you can take control and push your hardware to its full potential!

In a few days from now, AMD will unveil its new flagship graphics accelerator, the ATI Radeon HD 5970, which will intends to cement the brand's performance leadership over every product from rival NVIDIA. The HD 5970, codenamed "Hemlock", is a dual-GPU accelerator, with two codenamed "Cypress" GPUs in an internal CrossfireX configuration.

Built on the 40 nm process, these GPUs will feature 1600 stream processors each, and will each have a 256-bit wide GDDR5 memory interface to connect to 2 GB of memory (4 GB total on card). The clock speeds are where the specifications of these GPUs differ from their single-GPU avatar, the Radeon HD 5870. The core is clocked at 725 MHz, while the memory runs at 1000 MHz (4000 MHz effective).

The accelerator will not have a rear panel identical to those of other Radeon HD 5000 series accelerators. It has the usual broad air vent occupying one slot, while the other has two DVI-D and one mini DisplayPort (DP) connector. The mini DP connector can give out DVI output using a dongle, and in this way, support for ATI Eyefinity technology remains intact. The NDA covering this accelerator is said to expire on the 19th of November, not very far away.

PC water-cooling components specialist Danger Den is almost ready with its water-block compatible with AMD's upcoming dual-GPU accelerator codenamed "Hemlock". Almost, since the base-plate of the water-block has already been designed and molded, which makes for most of the product in itself, requiring only the top, its sealing, and fittings. The monolithic, full-coverage block base is made of copper. Its top portion reveals its intricately carved water channels. The copper grooves over the areas of the block which make contact with some of the most important components such as the GPU, memory, and bridge chip, increase area of heat dissipation. The block is CrossFire certified, and weighs about 3.00 lbs / 1.37 kg. Danger Den is waiting for an engineering sample from AMD, so it can complete running tests, and name its block after getting clarity on what AMD ends up naming Hemlock. AMD's new flagship graphics accelerator is expected to arrive in time for the crucial X-Mas shopping season.

AMD released its fourth beta of the ATI Stream SDK version 2.0, that provides the first complete OpenCL development platform. The release is certified to be fully compliant with OpenCL 1.0 by, the Khronos Group. A wide range of AMD GPUs as well as any x86 multi-core CPU supporting SSE3 instruction set are supported.

An interesting discovery by TechConnect Magazine shows that in these OpenCL drivers, are identifiers for a yet to be announced "Radeon HD 5900 Series", with the device IDs 689C and 689D, both marked under "Evergreen", like other members of the Evergreen family, such as Radeon HD 5700 and Radeon HD 5800 series. The most plausible explanation for "Radeon HD 5900 Series" could be that it is the name of the graphics cards based on the Hemlock GPU architecture, which pairs two Cypress GPUs onto one board. The driver also gives away device IDs, if not product names of GPUs based on the upcoming entry-level Redwood and Cedar GPUs.

Here is what four AMD Cypress GPUs can achieve with some careful overclocking, without needing any third-party cooling. Renowned overclocker Kinc sent us details of his latest achievement using four ASUS Radeon HD 5870 1 GB cards installed in a 4-way CrossFireX setup, all overclocked, and cooled by AMD's reference cooler, taking a shot at 3DMark Vantage (Extreme Preset). The four cards returned a score of X26,332 points, with an average frame-rate of 79.49 fps in GT1, and 74.83 fps in GT2.

To begin with the cards were overclocked to 1035/1290 MHz, up from reference speeds of 850/1200 MHz (core/memory). This was supported by raising the vGPU to 1.330V using GPUTool, from 1.015V. The platform to drive this feat comprised of an Intel Core i7 965 XE processor, cooled by Intel's reference (boxed) cooler, clocked at 4257 MHz. To seat them all was an ASUS P6T7 WS SuperComputer motherboard. The feat serves as a prelude to what the future holds in two "Hemlock" accelerators, which make use of two Radeon HD 5870 GPUs each.

Behold AMD's, and soon aimed to be the industry's most powerful graphics accelerator: Radeon HD 5870 X2 "Hemlock". Armed with two "Cypress" Radeon HD 5870 graphics processors, this dual-GPU monstrosity packs twice the shader compute power. From the looks of it, the card is slightly longer than its single-GPU sibling from the series, and is better ventilated, although the cooler design more or less resembles it. It draws its power from one 6+2 pin and one 6 pin PCI-E power connectors, just like two of its ancestors in the R700 and R680. Listed for pre-order on a European online store, a Radeon HD 5870 X2 by Club3D is priced at 677 EUR (incl. applicable taxes, 568.9 EUR excluding).
