The first specs of AMD's upcoming little brother of the awesome Radeon HD 7970 have leaked out, thanks to Turkish tech site Donanim Haber. AMD, of course, does not comment on rumors, but the site's source states that the cut-down Tahiti boards will ship with the same 384-bit memory bus that featured in the HD 7970.
To get the price lower than its bigger brother, the card will launch in two configurations: 1.5GB and 3GB. Core clock speeds also drop from 925MHz to 800MHz and the GDDR5 memory speed from 1.375GHz (5.5GHz effective) to 1.25GHz (5GHz effective).
At the moment, we don't know if the HD 7950 1.5GB/3GB will sport the same number of SIMD engines and stream processors as its higher-end equivalent, if it does, it might be the pick of the bunch when it comes to overclockers. Donanim Haber's source goes on to say that launch pricing of the HD 7950 3GB model will be $100 to $150 cheaper than the top-end 7970 3GB. AMD are of course keeping quiet on the situation, but a $100 - $150 cheaper card, capable of being overclocked sounds very nice indeed.
AMD have had quite a good launch with their Graphics Core Next bizzo, the Radeon HD 7970. But Team Green have a juicy new rumor today, that they might release their Kepler-based products early, and not in the earlier-reported March-April timeframe.
It would launch as early as next month with reports coming from ChipHell.com, where they say it will launch in February. The GTX 680 is rumored to sport the same performance as the AMD Radeon HD 7970, with a clock speed of 780MHz, but only 2GB of video memory. NVIDIA seem to be cheap on the video memory these days, which could indicate that the new cards might not do multiple monitors from the single card.
AMD's always thinking a few steps ahead, so throwing 3GB on the cards is great for Eyefinity users, and the 4K monitor support. NVIDIA only using 2GB is a worry, especially for 3-screen setups, or 3D Vision Surround setups that suck up that RAM like a GPU vacuum cleaner. Time will tell, and as usual, enjoy some TweakTown Salt.
Our latest poll had almost 4,000 people who answered, Which company made the best video cards in 2011?
This was actually one of the closest web polls we've ran in a long while with ASUS managing to take the title as the best video card manufacturer of 2011 as voted by TweakTown readers.
In a close second place was Palit with 15% of the votes and in equal third place was EVGA and MSI. Sapphire was just behind in fourth place with 14% of the votes.
The first pictures of PowerColor's upcoming Radeon HD 7950 PCS graphics card have surfaced, with reliable sources telling TechPowerUp that it is indeed true. As we can see from the below shot, the new PCS (professional cooling system) cooler design, uses a larger aluminum fin-stack heatsink that the previous PCS coolers used.
Heat is drawn from the GPU, taken to the fin-stack and a number of nickel-plated copper heat-pipes. Heat from there is then pushed out by the two 80mm fans. By the looks of the picture, it's a dual-slot card.
With its design and color scheme, one would think it's a Sapphire card. I do like the look of it though, those two 80mm fans should do a very good job at keeping the card cool, and an even better job when the card is obviously overclocked and working hard.

After paper launching the Radeon HD 7970 in late-December, it was rumored that AMD's slightly cheaper Radeon HD 7950 would launch in February, but according to DigiTimes, this isn't true. DigiTimes reports that the Radeon HD 7950 will launch at the end of January.
It was previously rumored to launch in February, but with NVIDIA possibly launching in March-April, AMD could have pulled their plans in quicker to stop Team Green from taking the field and running with the GPU ball. NVIDIA will now have to fight AMD, but whether they can successfully launch and not have issues moving to a new process like they did with Fermi, is the question.
This news was bought to you by the "sources within add-in board (AIB) partners" who told DigiTimes. Those pesky sources, upstream and downstream always have some good info. If this is true, we could see the launch of a (hopefully) decently priced HD 7950 in just a couple of weeks time.
Are you waiting for an HD 7950? Or are you proudly wearing Team Green and waiting for a next-gen GTX 560 Ti?
My birthday is in March and I'm pretty sure this is why NVIDIA are launching then, but the latest news is that NVIDIA does not want to paper launch the Kepler, so the launch of their first high-end Kepler part will only start once they have enough units for the first wave of customers.
NVIDIA originally had a Q1 2012 launch date in mind, with Quadro Kepler arriving in Q2 and Tesla Kepler arriving in Q3. But the new plans seem to indicate that NVIDIA will be launching the GeForce Kepler when they are able to ensure hard availability and have all of its partners covered.
AMD launched their GCN-based Radeon HD 7970 on December 22, 2011, but did not have any on retail shelves until closer to January 9th, 2012. NVIDIA does not want to repeat this and want to have stock availability in some what good numbers when they launch.
Have you held out for Team Green? Or did you take some of that Team Red action with the HD 7970?
VR-Zone have done some testing that really gets me excited: 4-way AMD Radeon HD 7970s with Battlefield 3. Oh boy. It's time to pull out my wallet. Before we get into the thick of it, some back story. VR-Zone upgraded their CPU cooling to an XSPC RX360 kit, and clicked it at 4.8GHz (Core i7-3960X).
They couldn't get any of the available overclocking tools to adjust voltages or core clocks on the HD 7970's beyond 1125MHz on the 4-way CFX setup, so they settled for AMD Overdrive to run their cards at 1100/1500MHz. First up they did some 3DMark 11 testing, with the the following results:
AMD's next-generation single-GPU Radeon HD 7970 is now available for sale, whilst not officially available until tomorrow, everyone likes to get in early. Newegg have already thrown their 7970s up for sale tonight.
Newegg have cards available from all of AMD's major North American partners, HIS, Gigabyte, XFX, ASUS, Sapphire, and PowerColor. Because they've just launched (and most likely because there's no competition), most of them are at the AMD MSRP of $549. The ASUS card is $589, and XFX's custom-cooled and overclocked model is $599.
There's no official word from AMD on the Radeon HD 7970 availability. Now, which of you amazing readers (or companies? ;)) would like to send me 2 for my rig? Am I kidding? I guess you'd only find out by sending me a few. On a more serious note, if you get your hands on one, be sure to comment and let us (and everyone else) know!
Although the AMD Radeon HD 7970 has been enjoying its time kicking the arse of virtually every other GPU in the world, the second GPU in AMD's 28nm-powered, GCN-busting lineup has been delayed.
AMD's Radeon HD 7950 won't reach us this month and has been delayed until February. A paper launch of the Radeon HD 7970 late last year is not the usual move for AMD, and they want to avoid similar problems with the HD 7950 when it launches, so a delay could actually be a good thing.
The Radeon HD 7950 is based on the same Tahiti core as the higher-end HD 7970 brother, except that 4 of its GCN (Graphics Core Next) compute units have been disabled. Because of this, it takes on the moniker "Tahiti Pro" versus the 7970's "Tahiti XT". The 7950 will sport 1792 streaming processors, 3GB of GDDR5 and a 384-bit interface. It should also feature the same amount of video outputs, allowing 6-screen support.
We posted a leaked Sapphire document yesterday and something I noticed were the black lines drawn through some of the details, mainly the stream processors on "Toxic ZX" and "Da Original" where it seems they had SP counts of 2304.
2304 is much higher than the 2048 stock, and according to PC Perspective, if this card were to come out, with the SP's running at 1225MHz, we could expect another 35- to 45-percent increase over the stock HD 7970.
If this were true, this could be a product AMD are keeping back from us all, waiting for NVIDIA to strike with their Kepler hammer. AMD have always been great at moving to another, smaller process and maybe this time with how good the 7000-series cards are, they struck gold. Decided to keep the treasure map to the true power of these cards, and if they've gotten there now... we could expect an AMD Radeon HD 8970 if it's true.
The first picture of a non-reference design AMD Radeon HD 7970, which comes from Gigabyte. The GV-R797OC-3GD is a factory-overclocked card, which makes use of Gigabyte's Ultra Durable VGA+ PCB and custom-design triple-fan WindForce cooler.
The Ultra Durable VGA+ PCB uses a 2oz copper layer for better electrical stability and heat distribution, ferrite-core chokes, low RDS (on) MOSFETs, hand-picked high-performance GDDR5 memory chips, and more. The cooler sports a combination of heatsinks and aluminum fin arrays to feed heat from the GPU, memory, and VRM to its copper heat-pipes and ventilated by three fans.
Gigabyte make use of a non-reference design, using non-reference cooling assembly, but most likely a reference design PCB, except, it's red. No details on clock speeds or pricing yet.
First off, Happy New Year! I hope you're all enjoying your festivities, while here in South Australia it has been a blistering 41C (over 104F) for the past 2 days straight and it is currently 43C right now. Joy! Onto the news! Our GPU editor sent this to me, and at first I thought it was tease, because he loves to do that to me. But, it was not, it was news that had floated onto the great world wide web.
Sapphire's leaked document, which reveals their non-reference AMD Radeon HD 7970's that they are currently baking in Sapphire ovens. Sapphire have an amazing six cards that will be non-reference, all ranging in features, speeds and more. One of them is the "Atomic RX" which goes from the original 1000MHz Core speed to a whopping 1335MHz. It sports the usual 3GB of RAM up from the 5500MHz stock speed, to 5735MHz. Output-wise, we have 2 x MiniDisplayPort, 1 x HDMI 1.4a and 1 x Single Link DVI.
There is also an "Atomic WC" which seems to be identical, but a water-cooled version. The other models include "Toxic 3G" which has a GPU clock of 1125MHz and 5600MHz RAM, "FLEX 6G" which as you guessed, has 6GB of RAM and 6 x MiniDisplayPort outputs with GPU clocks of just 925MHz and 5500MHz RAM, "VaporX 3G" which should have Sapphire's awesome VaporX cooler, with GPU clocks of 1010MHz and 5500MHz RAM. The final two are the Dual-Fan 3G with 925MHz Core and 5500MHz RAM and finally, the stock "Da Original" with 925MHz GPU clocks and 5500MHz RAM.
We've all seen the reviews on the spectacular AMD Radeon HD 7970, but what about its slightly younger brother? Well, we have some leaked specifications on the Radeon HD 7950 now, so let's see.
While the HD 7970 is based on the "Tahiti XT", the HD 7950 is based on the "Tahiti Pro". According to a slide posted by Donanim Haber, the Radeon HD 7950 sports 4 compute units disabled when compared to the HD 7970, which brings the number of stream processors down from 2048 to 1792.
These will be joined by 112 texture units, but the 384-bit memory interface and 3GB of GDDR5 memory remain unchanged. AMD also retain the same display output configuration with one dual-link DVI, one HDMI 1.4a, and two miniDisplayPort 1.2 outputs.
AMD readying dual-GPU Radeon HD 7990, launches with 6GB of RAM and ready to again, punch all other GPUs in the nuts
2011 was relatively quite for GPU releases, it featured more next-gen CPU and APU launches than anything else. We had a few different cards come out, but nothing revolutionary, until last week with AMD's launch of their Graphics Core Next (GCN) and the launch of the AMD Radeon HD 7970.
The new 28nm-based "Tahiti" chips have taken the world by storm, and have been a very impressive GPU, considering early drivers and whatnot. AMD are planning to launch a dual-GPU card codenamed "New Zealand" and will carry the AMD Radeon HD 7990 moniker, launching in Q1 2012.
This means we'll see AMD's dual-GPU beast before April Fools next year. Since Tahiti/HD 7970 is so energy-efficient, dual-GPU efficiency should be quite the sight to see. We should see two Tahiti GPUs sporting the same power of the single-GPU HD 7970's, with 6GB of total graphics card memory (3GB per GPU system).
AMD have launched their Radeon HD 7970 next-generation GPU today, and the reviews seem to be loving it. As a single-GPU card, it performs amazingly, and can actually keep up with the dual-GPU Radeon HD 6990 and NVIDIA GeForce GTX 590. There are plenty of reviews to check out, and one CrossFire review which got my blood pumping.
AMD's GCN is featured, Graphics Core Next, which is built on a 28nm process. The Radeon HD 7970 is now the fastest single-GPU in the world and does a damn good job punching the dual-GPUs square in the nuts, too.
Most of the first batches of AMD's Radeon HD 7900-series will use the original PCB we talked of earlier today, but the first pictures of the cost-effective Radeon HD 7900 PCB have surfaced on Asian media sites. AMD add-in board partners have the ability to use this cost-effective PCB if they'd like to fine-tune their pricing.
AMD is set to counter NVIDIA with some competition against their GeForce Kepler 104 (GK104) GPU. The cost-effective PCB is pictured above, with the shot above being the front of the card itself, with the two 8-pin PCIe power connectors, an 8+2 phase cost-effective analog VRM, most likely driven by a cost-effective CHIL controller, and a different display output connector loadout.
The cost-effective PCB has display outputs consisting of a two DVI, one HDMI and one full-sized DisplayPort. Partners can still use a single DVI connector, and keep their cards single-slot capable, something that would be great for HTPC, or SFF users.
The first picture of AMD's upcoming flagship single-GPU, the Radeon HD 7970, has had its PCB spotted. It reveals that the HD 7970 has the provision for two 8-pin PCIe power connectors, but on the sample picture below, there are two 6-pin power connectors. There have been other sightings of and 8 + 6-pin PCIe connectors.
The HD 7900 single-GPU reference board uses a digital-PWM power design, and what appears to be CPL-made single-phase PWM chokes, and Volterra-made regulators. The die is orientated diagonally, with a strong brace around it to reduce and stabilize the pressure applied by the cooling assembly. There are twelve memory chips around the GPU, as this chip provides a 384-bit wide memory interface, which is set to deliver a near 50-percent higher memory bandwidth over the previous generation.
It also sports redundant BIOS, loaded into two separate EEPROM chips that can be toggled using a small 2-way switch located next to the CrossFire connectors. Display connectors include one DVI, one HDMI, and two mini-DisplayPort connectors. The picture below shows the curvy back-side of the cooling assembly. Lookin' good, AMD!
We've had a fair amount of news on AMD's next-generation GPUs over the past six weeks, with the first news that the cards would be launching in January, then we had some rumored pricing, and then a few days ago we posted some leaked info on the AMD Radeon HD 7970 specs. Today, we have news of the feature-set that will be included on the GPU when it launches.
There are three main categories of feature updates: Graphics CoreNext, AMD Eyefinity 2.0 and AMD APP Acceleration. AMD have claimed that CoreNext will be a "revolutionary" new architecture that changes the way the GPU crunches numbers. Also keep in mind that GCN is the first new architecture since the HD 2000-series launches all those years ago.
Juniper is out, Cape Verde is in. The Radeon HD 5770, after two years on the force, is retiring. In it's place is the rookie AMD Radeon HD 7770. If you remember, AMD rebranded the HD 5770 as the HD 6770, so we saw nothing new. This is the first time in two years that AMD are giving its mainstream performance class products a performance upgrade.
As you can see from the above shot, the HD 7770 definitely looks like it's older, and much stronger brother, the Radeon HD 7970. It includes a large diameter fan pushing air down vertically and is a similar design introduced by the NVIDIA GeForce GTX 460. The length is also nearly the same, measuring in at 8.25-inches.
LeakedTT: NVIDIA to skip 600-series, jump straight to GeForce GTX 780? Did I mention it is nearly twice as fast as the GTX 580?
This was mostly unexpected, but then again, AMD have been waving their big red flag all over the Internet in the last few days due to the leaked AMD Radeon HD 7970 performance and specs. Today, we have PCINLIFE leaking an NVIDIA slide, that shows the difference in performance between their current single-GPU hero, the GeForce GTX 580 versus the GeForce GTX 780.
Say what? GeForce GTX 780?? Not GTX 680? Yes!
The above slide shows the performance between the current GTX 580 and the next-gen Kepler-based GTX 780. The test bed is a Core i7-3960X, Windows 7 64-bit, 297-Series driver, 2560x1600 resolution with both AA and AF enabled. The GTX 780 is virtually twice as fast as the GTX 580 if the chart is correct.
