Makes perfect sense building up bigger die with more transistors and wider memory bus. Nvidia used same approach with Titan. Its a bigger chip with wider memory bus when compared to 6xx series.

2. 512bit bus
Also makes sense. Somebody came with an idea that "Tahiti is slow on 4k" (cant test, such displays are not available here). 512bit bus with 4gb Vram will add enough performance for more displays in Eyefinity or on Higher resolutions.

3. Titan killer
Tahiti clocked to 1100Mhz is on similar performance level as stock Titan. I am not talking about benchmarks which were released on webs, i talk about tests i did myself. But when writing about reviews, soon after Titan AMD released GHz versions of Tahiti, claiming it has more performance as Titan. That was not completely confirmed, but I call it a draw... smile.gif

Fact is that Nvidia has to reveal new design to compete Hawaii. Adding more compute units will not work until 20nm.

1050MHz 7970 (aka 7970 GE) is beaten by the Titan by around 35%...

If your 1100MHz 7970 matches a stock Titan you had a broken Titan. Tahiti scales well with clocks but not quite that well.

I own a 7970GE I usually keep at 1225mhz core / 1650mhz mem and it's not up to par with the Titan in 99% of cases.

A 1225 core 7970 isnt keeping up with a Titan

I did a Titan vs 7970 comparison in my sig. Titan is at least 25-30%% faster than a 7970 at max OC. That said, I certainly don't see why its impossible for this new R9 to come close to Titan numbers....

Here's my relative performance chart from the article:

Didn't say it was... wink.gif

I'm saying in the rare circumstance where that would happen it's due to a very amd favoring game, and as my last sentence noted, 99% of the time that is not the case. This is a perfect example and that is a stock 7970GE.. http://anandtech.com/bench/product/764?vs=768 ... matched it or exceeded it more than once.

Not claiming it's on the same level, but in the games that do favor it, a 1225 core 7970 vs a 1050 one would do pretty well.

There has been a multitude of 7970 owners here who bought Titans including myself. Not a single word you stated above is true.

His Titan was clocked at 475 MHZ, that's why the 7970GE won.

At the time he did those tests...

For all testing the overclocks for each of the GPU setups are as follows:

Sapphire R7970 OC - 1225MHz Core / 1754MHz Memory
EVGA GeForce GTX Titan SC - 1100MHz - 1176MHz / 3506MHz Memory

Its not about clocks rather than using proper driver and proper settings for graphics. "factory defaults" in CCC are much higher at GPU utilisation as in case of Nvidia. Nobody of you noticed it?

also those articles contradict AMD's own slides detailing the very minor changes to the architecture that didn't even get dubbed "2.0"

To appease amd fans? lachen.gif If it's close to the 780 it will be 600 dollars. If it's not close to the 780 it'll be priced lower.

I can hear amd fans already complaining about the price when its finally released

idk, why did the 4870 demolish the 260 at $100 less, why did the 5870 rival the 295 with only one GPU at $100 less, why can you get a 7950 that beats a 670 when both are overclocked for as low as $200, why were 7970 ghz editions that clearly edged out 680s going for around $100 less...?
