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.
AMD have changed gears when it comes to their GCN launch on January 9, as most launches have the GPU manufacturer forcing AIBs to make cards based on the reference designs for at least the first 3 months after release.
This is good for AMD or NVIDIA, but for manufacturers, its hard to make your reference card stand out from the crowd. At launch, the cards are all pretty much the same thing and its only months later do we see some DirectCU models from ASUS, and TwinFrozr cards from MSI, etc.
But, AMD are unleashing their Tahiti Pro cards from the shackles of reference city... and SemiAccurate have heard from multiple sources that the HD 7970 will be able to sport non-reference designs from day one.
This will be a great thing for the launch of the HD 7000-series AMD cards, and their multiple AIB partners.
Quick nugget here, AMD's Radeon HD 7000 series are set to launch on January 9, 2012 according to reliable market sources that DonanimHaber spoke with.
AMD is expected to unveil two SKUs, the Radeon HD 7970 and Radeon HD 7950. This cards are based on AMD's new GCN, Graphics Core Next, and on a 28nm-based "Tahiti" silicon, which is a completely redesigned architecture.
January 9, January 9, January 9. It's nearly here.
This post comes inclusive of many grains of salt, but the first leaks on AMD's Radeon HD 7970 are here. The GPU is said to be released on January 10, 2012, where our VGA editor has promised me after he's done he's going to send me all of our samples, right Shane? ;)
Onto the rumor, 3DCenter have a compiled list of specifications for "Tahiti", from various sources and bits and pieces of info from here and there:
4.50 billion transistors, die-area of 380 mm², built on TSMC 28 nm process
Advanced GCN 1D architecture
2048 1D processing cores
128 TMUs, 48 ROPs
384-bit wide GDDR5 memory interface, memory clock slightly below 1 GHz, target bandwidth of 240~264 GB/s
AMD's next-generation high-end graphics card has been spotted, with images making their way onto the Internet. The new boards are marked as "Tahiti" and are believed to be the top-of-the-line single-GPU cards from AMD. This should be what the Radeon HD 7900-Series will eventually be.
The card, as you can see in the picture above, is quite long, roughly the same length as AMD's current Radeon HD 6970. It sports twelve GDDR5 memory chips, which means they use a 384-bit memory bus. It also includes two 8-pin PCI Express power connectors, which should give it up to 375W of power to suck down. The card, however, is powered by the SIG-approved 6-pin plus 8-pin config, which uses up to 300W of power.
It shouldn't be long until we have more concrete info, but generally, when there are leaks like this, the real things aren't far behind.
This is a bit unexpected, but a good move for Zalman. They have just announced their entry into the GPU market with the shipping of Zalman-branded GPUs to start shipping on December 13.
Zalman's first entry will be AMD Radeon HD 6000 Series GPUs, in three different models: Zalman HD6870-H , H-Zalman HD6850 and HD6770 Zalman-H. As you can tell from the model numbers, they are HD 6870, HD 6850 and HD 6770 GPUs. Nothing high-end yet, but I'm sure Zalman are just putting their toes into the water, for now.
Juicy one today, folks! It is rumored that AMD's flagship single-GPU graphics card will hit a US$549 price, with the slower model having a price tag of $449.
Remember, that this is just a rumor and nothing is guaranteed, but it gives us a peak into what we could expect when the cards launch. Right now, the names being thrown around are the AMD Radeon HD 7970 and Radeon HD 7950, just like the previous variants of cards in the 6000 Series. The pricing is reportedly coming from AMD and not card partners.
We're expecting an early January shipping estimate, and should hopefully hear some more news on the subject soon. Is it too early to wish for two of these puppies? I'll take CrossFireX 7970's, thanks.
