HIS Unveils its Much Awaited Radeon HD 7970 Graphics Card

Hightech Information System (HIS) today announced the launch of HIS 7970 3GB. The card is the world’s first 28nm GPU graphics card, pushing the graphics experiences to an unrivalled level! With a clock rate of 925 MHz, memory clock of 5.5 Gbps as well as a 384-bit memory interface, this new 7000 series HIS 7970 3GB offers maximum and crazy performances!

HIS 7970 3GB comes in a great value with the bundled the Eyefinity Dongle – the Active Mini DisplayPort to SL-DVI Dongle. In addition, the bundled HIS Weight Lifter makes the card last longer. It takes some weight off of the card and the PCIe slot, providing a simple but effective solution to prevent potential damage to the card due to the card’s weight.

AMD Denies Hidden GCN CUs in Tahiti

Over the past few days, we were hearing rumors from many quarters that AMD's "Tahiti" high-performance GPU may have been a deviation from an older specification, and that it really has 2304 stream processors spread across 40 GCN compute units (CUs), instead of the 32 the Radeon HD 7970 ended up with. Both AMD and NVIDIA create more redundant components on their chips than their SKUs end up getting, so they could increase yields, it's a process commonly known as "harvesting".

On Tuesday, AMD quashed the rumor in an e-mail to Bright Side of News, in which it said that Tahiti XT (Radeon HD 7970) makes use of all the CUs there are, on the chip. The 40 CU / 2308 SP rumor gained some weight with the fact that since AMD is venturing into unknown territory (TSMC's 28 nm process, built after quite some delays and failures), it could do some heavy harvesting. Examples of harvesting in recent past include Intel Sandy Bridge-E Core i7 processors, which use only up to 6 out of 8 cores on the silicon, and only up to 15 MB out of 20 MB available on it; and GeForce GTX 480, which used only 480 out of 512 CUDA cores available on the GF100 GPU.

Retail Radeon HD 7970 FOB Price Cut to $475, From $525

On the 22nd of December 2011, AMD launched its Radeon HD 7970, announcing that the cards will be available in the retail channels by 9th January, 2012. It permitted reviewers with access to AMD-made samples to post reviews on the 22nd, and told the press that it will have a FOB (freight-onboard) price (the price at which each card ships out of its place of origin, in this case Hong Kong, China) of US $525. Market sources told DonanimHaber that this price has been adjusted from $525 to $475. That doesn't necessarily mean that retail HD 7970 will cost lower than the $550 target retail price AMD talked about in several occasions. It will be up to downstream distributors and retailers on whether they want to convey this latest cut to the end-user, or keep a bigger "cut" (margin) for themselves. AMD hasn't officially announced any price updates so far.

Arctic Readies the Accelero Xtreme 7970 VGA Cooler

The soon-to-be-released Radeon HD 7970 is certainly getting its share of waterblocks but there are also air-based custom coolers coming for AMD's flagship card. One of them is Arctic's Accelero Xtreme 7970 which measures 288 (L) x 104 (W) x 54 (H) mm, weights 653 grams, and features 84 aluminum fins, five 6 mm copper heatpipes, a copper base, and three 92 mm PWM fans that work at 900 to 2000 RPM.

Arctic's cooler comes with pre-applied MX-4 thermal compound, is CrossFireX compatible, and is backed by a six-year warranty. The Accelero Xtreme 7970 costs $97.95 / €73.83 and is set to become available on January 31st.

Radeon HD 7950 Launch Delayed to February

On the 22nd of December, 2011, AMD paper-launched its Radeon HD 7970. By all measures, it appears like when the card hits retail availability on the 9th of this month, AMD will have a winning product at hand, for the price-segment it's targeting with that. According to latest reports, a leaked confidential email of AMD sourced by Guru3D (now redacted) says that AMD wants to launch Radeon HD 7950 on the same day of its retail availability, which happens to be in the first week of February, 2012. So no Radeon HD 7950 on the 9th of January, as we were earlier told about. The Radeon HD 7950 will be an important SKU for AMD, as it's more affordable than the $550 HD 7970.

AMD Radeon HD 7970 Overclocked to 1.70 GHz Core, 8.00 GHz Memory, Benchmarked

So you thought the 1.26 GHz core - 6.30 GHz memory feat was quite something, considering that Sapphire already has a card in the works that does 1.33 GHz core 5.73 GHz memory out of the box? Wait till you see the numbers an overclocker for the MyDrivers community achieved. With the right voltage assistance, coupled with the right kind of cooling (liquid nitrogen), the overclocker achieved a Radeon HD 7970 overclocked speed as high as 1700 MHz core, and 2000 MHz (actual) or 8.00 GHz effective GDDR5 memory speed, churning out memory bandwidth of exactly 384 GB/s. The best part is that this wasn't a hit-and-run feat, the setup was able to run 3DMark 11 and 3DMark Vantage. The scores are pictured below. Details of the volt-mod can be found at the source.

HD 7970 Overclocked to 1.26 GHz: 28 nm Tech Really Stretches Its Legs

Welcome to the first TechPowerUp news post of 2012! Read on for a couple of impressive overclocking feats with the HD 7970 graphics card.

It looks like the new AMD Radeon HD 7970 could be a bit of a dark horse and a lot more potent than its stock specifications would suggest – excellent for creating a competitive graphics card market. The reviews at stock speeds show the flagship HD 7970 to be around 10-15% faster than NVIDIA's flagship GTX 580, which doesn't seem all that impressive since the GTX 580 has been on the market for over a year now. However, what the reviews haven't really shown, is what kind of an overclocking monster the HD 7970 is. It definitely looks like AMD could have easily beaten the GTX 580 by a much bigger margin than they did, had they wanted to and it makes one wonder why they didn't.

VR-Zone have spent the New Year weekend overclocking this beast, having reached a whopping 1.26 GHz core clock speed with their HD 7970 - and decent benchmark improvements to go with it. Also, with the fan at 100%, the card never got above a very comfortable 68 degrees centigrade while running Furmark, which is amazing considering how this test is specifically designed to heat a graphics card to the max - but please see the update at the bottom of the article. The stock cooler may be noisy, but it's certainly very effective: an excellent result which will prolong the working life of the card.

EKWB Teases With Radeon HD 7970 Water Block

Another European company, EK Water Blocks (EKWB), is ready with its full-coverage water block for AMD's Radeon HD 7970 graphics card, the EK-FC7970. Unlike Aqua Computer's AquagrATIx 7900, the EK-FC7970 isn't launched, the company isn't taking orders yet, but it posted a teaser picture on its Facebook page. The picture reveals the block to use copper as its primary material, with an acetal top. It appears to have standard G1/4" threading. As a full-coverage block, it covers all the heat-producing components on the obverse side of the card's PCB, including the GPU, the twelve memory chips, and VRM. EKWB did not give out other specifications, price, or availability.

Gigabyte Radeon HD 7970 Custom-Design Graphics Card Pictured

Here is the first picture of a non-reference design Radeon HD 7970 graphics card. Made by Gigabyte, the GV-R797OC-3GD is a factory-overclocked graphics card, which makes use of a custom Ultra Durable VGA+ PCB by the company, and a custom-design triple-fan WindForce cooler. Its Ultra Durable VGA+ PCB makes use of 2 oz copper layer for better electrical stability and heat distribution, ferrite-core chokes, low RDS (on) MOSFETs, hand-picked high-performance GDDR5 memory chips, etc.

The cooler makes use of a combination of heatsinks and aluminum fin arrays to which heat from the GPU, memory, and VRM is fed by copper heat-pipes, and ventilated by three fans. Gigabyte also has a reference-design graphics card, which uses a reference-design cooling assembly, and most likely also a reference design PCB, except that it's colored red. It's not likely that red color PCB will be standard among AIB-branded retail cards, because the HIS and MSI cards pictured by OCUK recently, were found to have black-colored ones. There's no word of the pricing or clock speeds.
