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!
