AMD Radeon HD 7970 GHz Edition "Tahiti XT2" Detailed

We've known since May, the existence of a new high-end single-GPU graphics card SKU in the works, at AMD. Called the Radeon HD 7970 GHz Edition, the SKU is being designed to regain AMD's competitiveness against NVIDIA's GeForce GTX 680. We're hearing a few additional details about the SKU. To begin with, AMD has worked with TSMC to refine the chip design. The Tahiti XT2 will be able to facilitate significantly higher clock speeds, at significantly lower voltages, than the current breed of Tahiti XT chips.

Tahiti XT2, or Radeon HD 7970 GHz Edition, will ship with a core clock speed of 1100 MHz, 175 MHz faster than the HD 7970. The GPU core voltage of Tahiti XT2 will be lower, at 1.020V, compared to 1.175V of the Tahiti XT. It's unlikely that AMD will tinker with memory clock speed, since Tahiti already has a 384-bit wide GDDR5 memory interface, which gives it 264 GB/s memory bandwidth at 1375 MHz (5.50 GHz effective). According to the source, the new SKU enters mass-production next week. So best case, it should reach markets by late-June or early-July.

XT2 = second revision of the Tahiti XT chip.
I don't care what it is supposed to mean. In my opinion, it should be XTX, and nothing will change that opinion, because that's all it is, is my opinion.


It should be XTX, and that's that. There is a reason for that, but whatever, this is hardly something really worth talking about.

Binning a product hardly calls for new chip name. It is still Tahiti XT unless they did changes to the silicon which I doubt.

To normal buyers it's knows and GHz edition. Dave, you can call it XTX if you want to. :)

Grammar police calling!


:laugh:

And I will. ;) :roll:

I was saying GHz Edition long before anyone else here was, don't care WTF they wanna call it now, it's XTX, and that's that. :p

Meh, why would you think me as a normal person. I'm special, just like these chips!


You...you's just ewocka jabberwoka.

just a thought but they could have added resonant clock mesh to this and scored higher efficiency and clocks couldnt they, i doubt they did but i am expecting 8xxx might possibly feature it

and in so far as binning goes this is what i frequently alude to, just because they tell you the top end chip is such and such and hits a certain spec profile, that does not mean that that chip is/was the top binned, and AMD or any other company frequently does have a higher bin then your comercially aware of with other exclusive features that work or work best , this bin got freed up for us.:D.

anyways wheres the benches??.

Well for me it's XT PE! because i say so.

Impressive increase in clocks while lowering the voltage, worthy of commendation.

I doubt this will steal any of the thunder the GTX670 through 690 have, they impressed more than this, from the get go.

Nvidia price drop coming, Thank you :toast:

Hmmm 670's or shall it be 680's :rolleyes:

Agreed, Although I supposed/expected a few things:
A) AMD didn’t drastically deviate from the original chip design, TSMC just fixed their gates.
B) Will hold to the 250W TDP
C) Would maintain the current PCB design and power sections, that lets AIB keep work with the existing boards they have. If they have to change PCB/components that means less of a seamless transfer and less profit.
7970's consumes 210 watts link http://www.atomicmpc.com.au/Feature/296004,amd-radeon-hd-7970-reference-disassembly-guide.aspx

From http://www.guru3d.com/article/asus-radeon-hd-7970-directcu-ii-review/4 Radeon HD 7970 has 210 watts.

Believe it or not, the high end Radeon HD 7970 has a rated peak TDP (maximum power draw) of just 210 Watt, and that's really all right for a product of this caliber, features and performance.

From http://www.techspot.com/review/481-amd-radeon-7970/page2.html Radeon HD 7970 has 210 watts.

"it still chugs up to 210 watts under load

They already screwed themselves. Anyone who was willing to spend $550 for the 7970 already did so. And this little boost is not going to make anyone drop their 670s or 680s to spend $500 and get a whopping 5% boost.

Plus, nvidia's 670 is prime for a good price drop, which is all they would have to do to counter this card.
If they drop the price of the 670. ill get 2! I already was thinking about getting 2 670s

I doubt this will be 500 because price drops of gtx 680 or 670 will only push 7950 and 7870 prices even lower, so its either and will refresh these cards too or Tahiti xt2 will be 550$ like Tahiti xt launch price. Either way and is not being generous this Gen and are trying to be the ones controlling prices and pushing nvidia down unlike how its always Ben in the past

Im thinking the $4 billmark :eek:

right where the prices should be...:laugh:

Are there any good PC games for that super expensive equipment, cause I can play console ports better on proper hardware which is .... a very inexpensive Xbox360 or PS3. :laugh:

too late AMD..
it will only be little bit faster than a 670..
and trolled the users of the first batch 7970..

Lets just call it the 7990, and refer to the dual-gpu solutions as 7xxx X2 and call it a day. :p

An All-In-Wonder 7970 would be pretty awesome since you mention XTX. This isn't ATi anymore though. :(

I have ran my reference 7970 @ 1100/1500 since i bought it on launch day with zero issues on the default auto fan profile. Surely the new one will be a beastly clocker.

In computer graphics, ray tracing is a technique for generating an image by tracing the path of light through pixels in an image plane and simulating the effects of its encounters with virtual objects. The technique is capable of producing a very high degree of visual realism, usually higher than that of typical scanline rendering methods, but at a greater computational cost. This makes ray tracing best suited for applications where the image can be rendered slowly ahead of time, such as in still images and film and television special effects, and more poorly suited for real-time applications like video games where speed is critical. Ray tracing is capable of simulating a wide variety of optical effects, such as reflection and refraction, scattering, and dispersion phenomena (such as chromatic aberration).

so basically the hd7970 is a professional gaming graphics card since its still on par with a 680 in gaming and 2x more in compute power
