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.
As the launch of AMD's next-generation Radeon cards gets closer, we have some exciting leaked specs to share with you. From some leaked slides, the specs of AMD's first Graphics Core Next (GCN) chip, the Tahiti XT, which goes under the suave name of the AMD Radeon HD 7970, will sport 3GB of GDDR5 (and not the rumored XDR2 memory), 3.5 TFLOPS of power, 2048 stream processors, 384bit memory width at 5.5Gbps, total load consumption of up to 300W and an less than 3W for idle.
Display outputs include 1 x DVI, 2 x miniDisplayPort and HDMI, in terms of power connectors, it should have one 8-pin and one 6-pin. If these specs are true, we should expect the single-GPU Radeon HD 7970 to keep up with, and most likely beat in some games, the dual-GPU Radeon HD 6990 and NVIDIA GeForce GTX 590. It seems to be about 30-percent faster than the single-GPU Radeon HD 6970.
Once some great drivers are released for it, we should see more performance sucked out of the new cards. Two of these should see a game like Battlefield 3 run at Ultra quality, 1920x1080 at 120Hz absolutely maxed out with AA/AF at 120fps minimum, or 2560x1xx0 at 60Hz, minimum 60fps.
