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.

Judging from what i gathered in the review this card does not meet/perform as outlined in this "report"? I thought we were supposed to see improved performance along with improved efficiency :confused:

Performance crown is good but meaningless if it comes at the expense of efficiency, IMO :o

TBH i was expecting more from ATi, more efficiency & power. Guess i'll be waiting for 8xxx :ohwell:

Ive noticed this about both companies, its not worth moving ever year or 2, its best to wait 3-5 years before upgrading the video if you want it.

But honestly if they are fixing issues good on them.

5 years is really pushing it... at most 4 years should be ok... people should upgradde every 2 years though because youll beable to max out new games that way... no 5 year old card can max out skyrim for example.... and the best 2007 amd card was the hd3870

No five year old card can max out Skyrim cause it's an awful port from console that even runs poorly there...

How old is a 8800 gt now?

Aside from AA it can max out Skyrim I think.

I've found that graphically stock skyrim isn't demanding at all one bit.

The only demanding bit is shadows and that's because they run on the CPU.

My 9800 gt can still do most games pretty well. I had some trouble with metro 2033, crysis, and the stalker series. Most games worked pretty well

Are you challenging someone to prove you wrong because I am half tempted? I don't feel like removing my amd drivers to go to nvidea, and back again.

;) bet you cant max out skyrim with hd texture pack, and with skyrim HD 2k texture mod.. with a 5 year old graphics card ^^

which means getting 60fps on a 1080p 60Hz monitor

When I did use my 9800gt I only had a 1440X900 monitor and was fine with 30-45 fps. That is a bit steep asking for 60fps at 1080p

well yeah, 1080p is the base for games for 2012.... even 1200p... but 1080p is still used more and 60fps on a 60Hz monitor would be seamless without clipping and maxed out

but a 9800gt is not a 5 year old card yet... try it with a 8800 ultra

The ultra would be better than my gt. The 9800gt was a rebrand of the 8800gt. So 5 year old design. Here is a review of my 9800gt. http://www.overclockersclub.com/reviews/xfx_9800gt/9.htm
I prefer my 7970.
