The fact that Sapphire has been working on a Radeon HD 7970 graphics card with an obscene 6 GB of memory has been known since the end of 2011. The said card, the Sapphire Toxic HD 7970 6GB, has already taken shape, and was spotted running at CeBIT. Such as it is, AMD utilizes 2 Gbit GDDR5 memory chips in numbers of 12 to achieve 3 GB of memory across a 384-bit wide memory interface, on its HD 7970. Higher density GDDR5 chips are not available, at least not in bulk. So the only way Sapphire is doing 6 GB is by piggy-backing two 2 Gbit chips across 32-bit wide paths, each. As a result, these cards have memory chips on both sides of the PCB, obverse and reverse, and require a metal back-plate to keep the chips on the reverse side cool. The only reason we see consumers needing 6 GB of video memory today, is multi-monitor gaming. Even there, the impact of the increase to 6 GB memory (from 3 GB) is debatable.

GIGABYTE today introduced an extraordinary lineup of computers that are redefining mobility and powerful performance. The U2442V is a sleek and stunning 14" Ultrabook that provides fantastic performance with a 3rd generation Intel Core i5/i7 ULV processor, while the U2442N features the same incredible form factor, but has a powerful 3rd generation Intel Core i5/i7 standard voltage processor. Both models feature an excellent NVIDIA GeForce GPU, which provides remarkable graphics performance for multimedia and games.

Other models to be introduced include the P2542G, which is a 15.6" powerful gaming notebook with an exciting race car design; and the Q2542N, an excellent 15.6" mainstream notebook that delivers terrific versatility. Also to be showcased at CeBIT 2012 is the S1081, a 10.1" powerful business slate; the Booktop T1132N, an 11.6" revolutionary 3-in-1 notebook, tablet and desktop; the Booktop M2432, a sleek 14" notebook that provides desktop graphics performance through its unique docking station; and the AC21, an all-in-one PC that simplifies the desktop experience.

Dutch add-in board maker Club 3D has joined the Radeon HD 7800 party too by announcing not two but four cards powered by the Pitcairn 28 nm GPU. Two of those cards are based around AMD's reference model while the other two come equipped with a custom fansink utilizing the CoolStream High Performance Cooling Technology.

According to Club 3D its CoolStream solution "features high performance heatpipes that keeps the components cool and outperforms standard cooling solutions. Transferring heat from the center area to each fin, ensuring enhanced heat dissipation. The result is a dramatic increase of performance for your gaming and multimedia experience."

Japanese media has got a hold of the specifications table of AMD's Radeon HD 7800 series products, the HD 7870 and HD 7850. Hermitage Akihabara has not cited a source as such, so we assume it vouches for the accuracy of this table. The table reveals Radeon HD 7870 as having 1280 stream processors, a 256-bit wide memory bus width (derived from the memory bandwidth and clock speeds figures provided in the table), 80 TMUs, 32 ROPs, and clock speeds of 1.00 GHz core, with 1200 MHz (4.80 GHz effective) memory. This SKU has a typical board power of 175W.

The slide details the HD 7850 as having 1024 stream processors, 64 TMUs, 32 ROPs, the same 256-bit GDDR5 memory interface, with the same memory clock speed as the HD 7870, but with a lower core clock speed of 860 MHz. the board power for the HD 7850 is mentioned to be under 130W. Interestingly, 2 GB is standard memory amount for both cards. The Japanese site mentions the official launch date of HD 7800 series as being March 8, but also goes on to add that market availability (we're assuming they mean the Japanese market), is only expected on/after March 19.

XSPC is finally ready with a full-coverage water block for AMD Radeon HD 7970 and HD 7950 graphics cards (AMD reference PCB). The block is design to keep the card within the size specs. of a single expansion slot, while providing liquid cooling to all hot components on the obverse side of the PCB, including the GPU, the 12 GDDR5 memory chips, and the VRM. Measuring 220 x 142 x 9 mm (18 mm at ports), the main portion of the block is milled out of a block of copper, while the portion over the VRM is milled out of aluminum.

The portion of the block that's over the GPU is ridged, making copper micro-fins, that increase dissipation of heat to the coolant. The top is made of CNC-cut stainless steel. The block is ready for CrossFire setups with four G1/4" ports, two G1/4" plugs are included. Listed on the company's online store (currently out of stock), the XSPC Razor 7970 is priced at £82.67 (US $131).

The top desktop graphics card based on the NVIDIA GeForce Kepler 104 (GK104) ASIC, which has come to be known as GeForce GTX 670 Ti, is reported to use a 5 NVVDD phase power supply (VRM) design that draws power from 6-pin and 8-pin power connectors. The card will hence have 300W of power at its disposal. NVVDD phase 1 and 3 will be wired to the 6-pin connector; phase 2, 4, and 5 to the 8-pin connector. NVVDD phases 2, 4, and 5 feed power to the GPU, while phases 1 and 3 power the GDDR5 memory and other components on the board.

Teased by its maker earlier this month, the PowerColor Radeon HD 7970 LCS (Liquid Cooling System) Edition graphics card has found its way onto Overclockers UK's website where it can be found on pre-order priced at £599.99 (~ $951 / ~ 718 Euro).

PowerColor's new, Tahiti-powered card comes equipped with a single-slot EK Nickel Acetal waterblock and features a core clock of 1050 MHz (up from the stock 925 MHz), 2048 Stream Processors, a 384-bit memory interface, 3 GB of GDDR5 VRAM set to 5700 MHz (5500 MHz stock), PCI-Express 3.0, DirectX 11.1 and OpenGL 4.2 support, CrossFireX and Eyefinity capabilities, and four display outputs - one dual-link DVI, one HDMI and two mini DisplayPorts.

The Radeon HD 7970 LCS is backed by a two-year warranty and should start shipping before the end of this month.

The launch of AMD's Radeon 7800 series is on course for March, as AMD wants to complete the launches of the entire Radeon 7000 series before NVIDIA even has its first GPU out. Radeon HD 7800 will be designed to occupy key price points in the sub-$300 market segment, where it strikes price-performance sweetspots for gamers. Central to this series is a new 28 nm GPU, codenamed "Pitcairn", from which will be derived three SKUs: the Radeon HD 7870, Radeon HD 7850 2 GB, and Radeon HD 7850 1 GB. The specifications look like this:

Radeon HD 7850

Radeon HD 7870 specifications follow.

Club3D joined the HD 7700 party by launching its pair graphics cards, the Radeon HD 7770 (CGAX-7772) and Radeon HD 7750 (CGAX-7752). The two cards appear to be contract-manufactured by TUL, the company behind PowerColor and VTX3D, as the card designs bear a striking resemblence to those by the two brands. The HD 7770 of course is based on AMD's reference board and cooler designs, with a red-colored PCB. The HD 7750, on the other hand, features a refreshing single-slot cooler. The HD 7700 packs 640 GCN stream processors, and feactures clock speeds of 1000 MHz core, and 1125 MHz (4.50 GHz GDDR5 effective) memory; while the HD 7750 packs 512 stream processors, with clock speeds of 800 MHz core and 1125 MHz (4.50 GHz GDDR5 effective) memory.

AMD has just launched the new Radeon HD 7700 series, in a bid to cement its competitiveness in the sub-$200 market-segment. The Radeon HD 7700 series, according to AMD, is designed to offer "the world's most advanced graphics for everyone." The series is based around a new ASIC built on the 28 nm fab process, codenamed "Cape Verde". The new chip takes advantage of the Graphics CoreNext architecture, and features 10 GCN compute units, amounting to 640 stream processors; 40 TMUs, and 16 ROPs; and a 128-bit wide GDDR5 memory interface.

The Radeon HD 7770 has all components on the chip enabled, and features clock speeds of 1000 MHz core, and 1125 MHz (4.50 GHz GDDR5 effective) memory, yielding 72 GB/s memory bandwidth. This card draws power from a 6-pin PCIe power connecor. The Radeon HD 7750, on the other hand, features 512 stream processors, and 32 TMUs. The rest of the specifications are identical to the HD 7770, except core clock speed: 800 MHz. The Radeon HD 7770 is priced at US $159, while the HD 7750 is available as low as $109.

TUL Corporation, a leading manufacturer of AMD graphic cards, today added a new HD7970 graphics solution with dual cooling fan design: the PowerColor HD7970. Equipped with PowerColor exclusive cooling solution, the latest HD7970 lowers down 10% temperature through 92 mm ultra big fan and unique SSU-shape heat pipe design; while dissipates the excessive heat efficiently, it delivers low noisy level up to 15% quieter than reference version, providing no-compromise cooling effect with silent gaming environment.

The PowerColor HD7970 has core clock at 925 MHz and memory clock at 1375 MHz; with compatible with PCI Express 3.0, enabling unprecedented gaming performance by doubling the bandwidth per lane of previous generation. With 3GB GDDR5 onboard memory, the latest HD7970 allows the highest bandwidth for demanding DirectX 11.1 gaming title, delivering the astonishing image quality up to six displays by utilizing AMD Eyefinity technology.

In the coming week, AMD will release its Radeon HD 7700 series, which aims to increase its competitiveness in the sub-$200 market. The latest specifications exposé reveals AMD's new design strategy: Instead of increasing components such as stream processors and ROPs, which would increase transistor counts, and unnecessarily increase power draw, AMD is counting on a lesser number of better-configured Graphics CoreNext stream processors. While the previous-generation HD 5770/6770 "Juniper" GPU featured VLIW5 stream processors, the new "Cape Verde" GPU, which will go into making up Radeon HD 7770 and 7750, will feature GCN stream processors. Apart from architectural performance improvements, AMD is counting on increased clock speeds to do the trick. The specifications are listed below.

Cape Verde Physical

• Built on TSMC 28 nm process, ~1.5 billion transistors
• 10 Graphics CoreNext Compute Units (CUs)
• 640 stream processors
• 40 TMUs, 16 ROPs
• 128-bit wide GDDR5 memory interface

The HD7970/HD7950 X Edition also features ultra cooling design. With two 92 mm ultra big fan and SSU-shape heat pipe design, this efficient cooling solution maximizes the speed of heat dissipation, but minimizes the noisy level, creating most pleasing environment for gaming.

As if two custom Radeon HD 7970s (the Vortex and LCS models) aren't enough, PowerColor has today revealed another HD 7970 card that goes beyond AMD's reference design. Seen below, this third custom Radeon HD 7970, likely part of the PCS Series, comes equipped with a dual-slot cooler boasting two fans and (at least) three copper heatpipes, and features 2048 Stream Processors, a 384-bit memory interface, 3 GB of GDDR5 VRAM, CrossFireX support, and five display outputs (dual DVI, dual mini DisplayPort, one HDMI).

PowerColor hasn't said anything about the card's clocks or price tag but hopefully those will be revealed later this month.

Ushering the finest and most capable graphics card based on new AMD "Tahiti" 28nm GPUs, the ASUS HD 7970 DirectCU II TOP uses a factory-overclocked core and 3 GB of GDDR5. It is cooled by the exclusive DirectCU II, a dual fan thermal design with six copper heatpipes and a large dissipation area that leads to the lowest temperatures and quietest operation of any HD 7970 card.

ASUS DIGI+ VRM 12-phase digital power delivery comes to graphics cards improved with Super Alloy Power components, while overclockers are bound to appreciate the inclusion of exclusive VGA Hotwire hardware overvolting and GPU Tweak software tuning. The new cards further support adapter-free AMD Eyefinity 6.

More Tahiti goodness is coming up as PowerColor has confirmed with a nice clear photo that it's working on a watercooled Radeon HD 7970 card. Dubbed LCS (Liquid Cooling System) HD7970, the card comes equipped with a (single-slot) waterblock from Slovenia's own EK team.

PowerColor's watercooled card also features 2048 Stream Processors, a 384-bit memory interface, 3 GB of GDDR5 VRAM, DVI, HDMI and dual mini DisplayPort outputs, plus DirectX 11.1 capabilities, CrossFireX support, and a PCI-Express 3.0 interface. No word on the card's clocks (yet) but they should be higher than on stock models. Expect more info later this month.

Japanese company Mouse Computer announced two new desktop PC models featuring the latest hardware and Iiyama ProLite X2377HDS-B IPS LED-backlit LCD display. The 23-inch IPS display provides 1920 x 1080 resolution with a response time of 5 ms. The first of the two desktops featuring it is the LM-iS615B-P23S, and the other is LM-i735X-P23S (pictured in this order below).

The LM-iS615B-P23S features a micro-ATX slim-tower measuring 100 x 393 x 364 mm (WxDxH). It is driven by Intel Core i5-2500 processor, with 8 GB dual-channel DDR3-1333 memory. It lacks discrete graphics, and relies on the embedded Intel HD 3000 graphics. Storage is care of a 500 GB 7200 RPM HDD and DVD-RW drive. It is powered by a 300W PSU. Windows 7 Home Premium x64 is the OS of choice.

A little earlier this month, we were treated to pictures of Sapphire's dual-fan Radeon HD 7950 OC graphics card. It appears that the card pictured earlier is not the only non-reference design HD 7950 from Sapphire, as it has a slightly more affordable single-fan model in the works. This model likely sticks to AMD reference clock speeds of 800 MHz core, 1250 MHz (5.00 GHz GDDR5 effective) out of the box.

The single-fan HD 7950 appears to have a blue-colored PCB that is likely to be AMD's cost-effective reference design. The cooler appears to have a compact heatsink that is cooled by a single central fan. Display outputs include two mini-DisplayPort, and one each of HDMI and DVI. We're also hearing from the source that 900 MHz core with unchanged (1250/5000 MHz) memory will be the maximum factory-OC permitted by AMD to AIB partners. That is not to say that the HD 7950's OC potential beyond that will be limited in any way.Update: Augmented with more images from Expreview.

Pictures of the Sapphire HD 7950 3 GB graphics card have been leaked on the Guru3D forum by user asder00. No further details or specifications were given other than "Product name: Sapphire HD7950 3G GDDR5 PCI-E HDMI/DVI-I/DUAL MINI DP OC VERSION".

As can be seen by the cooler, this is a non-reference design - at least for the cooler. The cooler is coloured black, has a very modern, sharp, angular and somewhat futuristic look to it and sports two large Sapphire-branded fans. Of course, it has heatpipes and five are visible. The design of this cooler suggests that it should work quietly and cool efficiently. Connectivity is aided and abetted by one DVI port, one full size HDMI port and two mini-DisplayPorts, like on its bigger brother the HD 7970. Moving on to the box, one can see that it has a 384-bit bus and 3 GB GDDR5, again like the HD 7970. The box also shows a logo with "OverClock" written boldly in white on it. The inevitable attractive lady box art in this instance has her wearing a grey top, a partial face mask and a helmet from what looks like the wars of yesteryear, plus she is carrying a rifle over her shoulder.

Chinese AMD Radeon add-in board (AIB) partner and motherboard major Yeston, displayed a Radeon HD 7970 PCB, which bears the AMD branding, and is reportedly AMD's cost-effective "Tahiti" PCB. It is quite likely that this PCB will be used for Radeon HD 7950, apart from affordable HD 7970 cards. Radeon HD 7950, like its costlier sibling, will have a 384-bit wide GDDR5 memory interface.

Its designers seems to have done some clever cost-cutting which will make cards based on it more affordable (or at least more profitable), without sacrificing quality much. The PCB uses a 8+1+1 phase VRM, consisting of cost-effective ferrite core chokes, LFPAK MOSFETs, and probably a UPI-made VRM controller. Yeston will most likely use a top-flow cooler, and hence made room for two DVI connectors next to one each of HDMI 1.4a and standard DisplayPort 1.2. The dual-BIOS feature of AMD's high-end reference HD 7970 PCB is blanked out on this PCB.

GIGABYTE today announced an outstanding lineup of ground breaking mobile computers at CES 2012.
