Well, today is the day! You should be on the lookout for the brand new AMD Radeon HD 7970 3GB graphics cards that we first were able to show you on December 22nd! And today we posted our review of the retail-ready XFX Black Edition Double Dissipation card with overclocked speeds - be sure to give it a read as well.
Scheduled to be on sale today, I decided to take a quick look around the Internet...
Newegg is on auto-notify for ALL Radeon HD 7970s...
Amazon shows a single card as in stock, from Sapphire, selling for a staggering $683. But it has Prime shipping!
Our search at TigerDirect came up empty.
Someplace called ExcaliburPC shows one for sale at $637, but is backordered.
Finally, Provantage shows a whole lot of nothing...
I am hoping that stock will improve as the day goes on and some of these vendors start to show availability in their systems. Otherwise, AMD is going to have a lot of explaining to do.
Feel free to post below if you find them for sale or not!

If somehow you ended up feeling that Ryan missed something about the HD 7970 that was important to you, we offer a long enough list of HD 7970 reviews that you will find it somewhere. Come next week when these cards hit the market at about $800 apiece (the MSRP is $550USD so hope that number is inflated), you might want to know just how well the cards scale, assuming you are able to spend the better part of $2000 just on your graphics subsystem. The Guru of 3D has answered your Croesus-like desires by running two HD 7970's in CrossFire. The power usage turned out to be quite interesting, the total power used by two HD 7970s is comparable to that of a single HD 6970, which will at least help you save a bit on your PSU and electricity build. More important to most is the performance scaling, which Guru3D tested exhaustively and are happy to report scaling between 1.6 to 2 times the performance. Keep in mind you need huge resolutions to make this worth your investment, it takes a lot of money to play Battlefield 3 @ 2560x1600.
"We review the AMD Radeon HD 7970 in Crossfire. With two reference cards in-house, we figured well, you might be interested in some multi-GPU lovin from AMD.
Let's take it to the next level -- multi-GPU gaming in 2-way Crossfire mode."

According to a story posted over at Fudzilla, there are new details leaking out about the February release of the AMD Radeon HD 7700-series of graphics cards. Based on the 28nm Cape Verde chip we first heard about last month at the AMD GPU Tech Day in Austin, this is the smallest die based on the new Southern Islands architecture. If you haven't read about all the changes that SI brings to the table (and there are many) then you should check out our Radeon HD 7970 review while you're here.
The specifications of the Radeon HD 7700 (Cape Verde XT) according to the leak are 896 stream processors (14 CUs), 56 texture units and 16 ROPs with a clock speed of 900 MHz. The memory system will be based around 1GB of GDDR5 on a 128-bit memory bus at a 1375 MHz clock rate for a total bandwidth of 88 GB/s. The Radeon HD 7750 (Cape Verde Pro) steps down to 832 stream processors (13 CUs), 52 texture units and 16 ROPs with a 900 MHz clock speed. The memory system will still be 128-bit with slightly slower memory for a total of 80 GB/s of bandwidth.
Compared to the Radeon HD 7970, these specs are pretty meager. The Tahiti GPU has 2048 stream processors and a 384-bit memory bus which would likely make a dramatic difference in performance, as expected Still, for the estimated $149 price tag AMD could have a winner on its hands.
Our estimation of the Cape Verde GPU based on the rumored specifications. It is also possible that AMD would remove the dual geometry engines at the top and go with a single.
Finally, there is less information about the 7800-series (Pitcairn): it could include a 256-bit memory bus and will obviously include more compute units for its $299 and $249 price tags. If those leaked prices are legit, that is a HUGE gap in price between the HD 7870 and the HD 7970 currently set to be sold at $549!

The big talk during the holiday break was AMD's release of the Radeon HD 7970 3GB graphics card - the new single-GPU performance leader. I gave the card our Editor's Choice award for simply impressing the hell out of us, all while keeping power consumption in check thanks to the TSMC 28nm process technology it is built on. Being the first card to support the upcoming DX11.1 and PCI Express 3.0 are just a bit of icing on the fruitcake.
During our talks with AMD they teased a dual-GPU version of Southern Islands they were calling "New Zealand". According to a report from Softpedia that card might be available sooner than we thought - sometime in the first quarter of 2012. Because the new Tahiti GPU is actually more power efficient than Cayman, seeing the pending Radeon HD 7990 with two full powered GPUs isn't out the question though we would expect to see slightly lower clock speeds.
Because of the ZeroCore Technology implemented this generation of GPU from AMD, the HD 7990 will be able to run at basically the same power levels as the Radeon HD 7970 at idle and at the Windows desktop.
The most interesting part? This would give the HD 7990 a 6GB frame buffer, 3GB per GPU as we see today on the HD 7970. Chances are this would give the graphics card more memory than many of our readers primary computer...
If you are interested in this type of card, start saving your pennies now. When the Radeon HD 6990 launched (the Cayman-based dual-GPU card) it was priced at $699 and never went any lower. With the price of a single Southern Islands GPU curently at $549, expect to see even higher numbers than the HD 6990 has. I hope we don't see the same availability issues with the pending HD 7990 release but you can't be sure.
The First 28nm GPU Architecture
It is going to be an exciting 2012. Both AMD and NVIDIA are going to be bringing gamers entirely new GPU architectures, Intel has Ivy Bridge up its sleeve and the CPU side of AMD is looking forward to the introduction of the Piledriver lineup. Today though we end 2011 with the official introduction of the AMD Southern Islands GPU design, a completely new architecture from the ground up that engineers have been working on for more than three years.
This GPU will be the first on several fronts: the first 28nm part, the first cards with support for PCI Express 3.0 and the first to officially support DirectX 11.1 coming with Windows 8. Southern Islands is broken up into three different families starting with Tahiti at the high-end, Pitcairn for sweet spot gaming and Cape Verde for budget discrete options. The Radeon HD 7970 card that is launching today with availability in early January is going to be the top-end single GPU option, based on Tahiti.
Let's see what 4.31 billion transistors buys you in today's market. I have embedded a very short video review here as well for your perusal but of course, you should continue down a bit further for the entire, in-depth review of the Radeon HD 7970 GPU.
Southern Islands - Starting with Tahiti
Before we get into benchmark results we need to get a better understanding of this completely new GPU design that was first divulged in June at the AMD Fusion Developer Summit. At that time, our own
lovely and talented Josh Walrath wrote up a great preview of the architecture that remains accurate and pertinent for today's release. We will include some of Josh's analysis here and interject with anything new that we have learned from AMD about the Southern Islands architecture.
When NVIDIA introduced the G80, they took a pretty radical approach to GPU design. Instead of going with previous VLIW architectures which would support operations such as Vec4+Scalar, they went with a completely scalar architecture. This allowed a combination of flexibility of operation types, ease of scheduling, and a high utilization of compute units. AMD has taken a somewhat similar, but still unique approach to their new architecture.
Speed Bumps and Unlocked Processors
AMD has announced the latest members of their fairly successful APU series for both the desktop and the mobile markets. The original release in June of this year saw the first fully integrated 32 nm APUs from AMD. These proved to be quite popular with their decent CPU performance and outstanding integrated graphics speed and quality. The launch was not entirely smooth for AMD though, even though the company had been shipping products to partners and OEMs for some months.
The desktop saw limited SKUs, and the availability of the top end parts was disappointing to say the least. AMD and their partners at GLOBALFOUNDRIES were not able to produce enough usable chips to supply demand. Quantities were tight throughout the summer, and the mobile market did not see as big of a boost for AMD as was hoped. AMD did get a lot of new business though, as the thermal and power envelopes of these A-series chips were able to match that of Intel.

One quickly forgets about the initially released reference GPUs once the cards with custom coolers, capacitors and PCBs arrive on the market all cool and factory overclocked. Usually the original GPU and card designer, in this case AMD, licenses theit top tier partners, like MSI , Gigabyte or Sapphire, to sell cards following a design that AMD provides along with the license to design and sell the cards. As SemiAccurate points out, this has lead to a market where the only unique feature they can add is usually armed and wearing a bikini. After the card has been on the market for a while, then AMD allows non-reference designs to appear for some cards from some manufacturers.
Not so with one of the four lineups of GPUs soon to arrive on the market, AMD will be freeing us from the tyranny of Ruby in different outfits and allow their partners to modify the Tahiti Pro cards from the get go. Expect to see a large difference in the appearance and specifications of AMD's new high end series of cards. That is the only one of the four to get this treatment, Tahiti, Pitcairn and Pitcairn XT cards will still come out only as copies of the reference card design. This may change over time but for now the idea of custom cooler, power distribution and PCB design is something to look forward to in the coming years.
"Back to the new news, and it concerns the Tahiti Pro card. Word has reached SemiAccurate that Tahiti Pro will be unconstrained to the normal reference designs. If you recall, most GPU manufacturers will force AIBs to make cards based on the reference design for the first 3 months or so, and there are a variety of very good business reasons to do this.
Unfortunately, it leads to a problem where the reviews all are the same, mainly because all the cards are the same. The main difference between manufacturers comes down to what color the AIB decides to put on the chrome bikini of the girl with the big sword riding the mythical beast just below their logo. We are partial to Hafnium bikini’s on women riding giant Were-moles around here. Luckily, Tahiti Pro changes this."

AMD has had a good run with it’s 6000 series cards, but the show must go on and in that vein the company has been working on manufacturing their next generation of graphics cards. The new cards will be of the 7000 series variety and will be broken into the same two architecture model for the upper tier/performance parts and the budget and small form factor fitting parts with the Tahiti and Pitcairn GPUs respectively. As the launch window for the new graphics cards gets closer tidbits of information is starting to leak out. In fact, popular news and rumor site Fudzilla recently got their hands on a few leaked 7000 Series details!
Included in the leaks are information on the performance parts as well as the mid-range GPUs. On the Tahiti front, a photo of two AMD Radeon HD 7900 series cards in CrossfireX has emerged, showing the underside of the PCB, crossfire connectors, PCI-E power connectors and a possible opportunity for a math wiz to approximate the size of the card based on the known dimensions of that particular PSU (heh). Because there are 12 memory chips on the card, the site claims that the rumored 384-bit memory bus is all but confirmed. Further, the cards require both an 8 pin and 6 pin PCI-E PSU connector for power. These cars are engineering samples and things could change between now and release; however, the speculations seem reasonable. The Tahiti based graphics cards will allegedly be priced at $399 and $499 for the 7950 and 7970 respectively.
The Pitcairn GPU based cards will represent the mid-range of AMD’s 7000 series lineup. According to un-named sources, Fudzilla believes that AMD may be releasing the mid-range graphics cards around February 20th, 2012 or about a month after the Chinese New Year. The cards will be carrying similar naming conventions to their predecessor, including the Radeon HD 7850 and Radeon HD 7870. Due to Tahiti pricing, it’s likely that the mid-range 7000 series graphics cards will be priced at $199 USD for the 7850 and $299 USD for the Radeon 7870, at least until Nvidia’s Kepler arrives to shake up the pricing.
Personally, I’m excited for the 7000 series, and am anxious to see what kind of F@H and gaming performance I can wring out of it! Are you planning an upgrade next year, or will you skip this generation?

AMD has slowly but surely been taking over the desktop computer. The AMD brand is slowly encompassing all of the components inside AMD powered computers. For the past few years, the company has been heavily investing in and marketing the idea of an all AMD powered computer filled with parts certified to work with each other and deliver a consistent platform (ie Spider, Fusion, and AMD Vision) experience by using an AMD CPU, motherboard, and graphics card together.
It seems as if AMD was not happy with the amount of case badge stickers from other companies for the remaining parts; however, as the company officially announced today that AMD is bringing to market is own AMD branded DDR3 memory modules with the assistance of experienced memory manufacturers Patriot and VisionTek. VisionTek will be making the modules available in the US through their distributor D&H, while the Patriot modules are generally available in the US already.
A close up shot of the Performance Edition provided by AMD.
The new AMD RAM will be controlled end-to-end on the design, oversight, and certification side by AMD while the physical processes of constructing and mass producing the modules will be in the hands of partners (currently Patriot and VisionTek). AMD will offer three speed tiers with capacities including 2 GB, 4 GB, and 8 GB (matched 4GB kits). Specifically, the three speed tiers will be labeled Entertainment Edition, Performance Edition, and Radeon Edition memory in order of slowest/cheapest to fastest (and most expensive). The Entertainment Edition should be shipping soon in the last quarter of 2011 and has at least a planned soft launch of November 2011. Entertainment Edition memory will be the slowest tier, weighing in at 1333 MHz or 1600 MHz and will be best suited for low power systems and HTPC applications. Performance Edition on the other hand will come only in 1600 MHz, low latency, and matched pair modules. This middle tier of AMD RAM is planned to launch in January of 2012. Last up is the Radeon Edition DDR3 which will come in 1866 MHz RAM that has been tuned, tested, and certified for certain system configurations.
To make things a bit more interesting, AMD will be allowing software overclocking of the DDR3 RAM via its AMD OverDrive application, along with planned support for Intel XMP memory overclocking profiles.
The company is claiming up to a 20 % platform performance increase in gaming, and in our own tests we did find a noticeable increase in performance with AMD’s Llano APUs when using higher clocked memory modules. For example, in Dirt 3 the system was able to hit a minimum of 31 FPS (frames per second) when using the A-3850 APU and 1866 MHz whereas with slower clocked modules, the system dipped under the ideal 30 FPS minimum that gamers like to see. Further, by using higher clocked RAM, we managed to get a 25 % increase in performance out of StarCraft II, so AMD’s claims aren’t too far off the mark.
I’ll admit that when rumors surfaced a few months ago that AMD might be entering the DRAM market, I was a bit worried. The company has only recently stopped seeing red on their profitability statements, and the DRAM market has notoriously thin margins. Especially after the lackluster Bulldozer launch and bout of layoffs, I really did not want to see AMD try to spread itself too thin. On the other hand, they are not doing the manufacturing themselves, opting to leave the physical processes up to other companies who are already in the business and know how to stay afloat in the crowded waters. The branding and ability for AMD to offer a platform consisting of an AMD CPU, graphics card, motherboard, and RAM is an advantage that their competition simply can’t match, and its good to see the company taking advantage of that. I don’t expect AMD to start making power supplies, hard drives (though I wouldn’t say no to a nice Radeon RAM Drive ;) ), and cases, but the core components are now all united under the AMD banner and the barrier to entry for new DIYers (do it yourself/self built computers) is now lower. As long as the company can make it work, I’m all for it. What do you guys think of the new AMD branded RAM, is it something you’d use?
