If we look at Wireless Security Auditor, ElcomSoft's most popular tool the situation changes slightly, as a single K20 delivers 85,000 passwords per second, compared to the 65,000 on the GTX 690. Then again, Nvidia still lags behind AMD, as the three year old Radeon HD 5970 handles 103,000 passwords per second, and HD 6990 increased that to 129,000. In that aspect, not even the K20 can reach performance achieved by a single consumer AMD card. This is also the reason why a sea of secy agencies went forward and acquired AMD Radeon HD 5990 and HD 6990 cards, instead of going professional with the Tesla and FirePro cards. AMD now has a dual-GPU card for professionals and we were told the results blew the competition out of the water and are one of major reasons why AMD never released the consumer version of the card.
I think that 48Rops + 2560 shaders @ 1000 mhz is enough to match titan, if it is really 50% faster than 680.
I don't know... based on this article AMD is not going to release anything new until 2013 Q4 or even till 2014 Q1:

Even the specs you listed don't sound probable on 28nm node. HD7970 GE reference review sample card's cooler was pretty loud at just 1050mhz. After-market 7970s are more efficient, but they have superior components and much more expensive heatsinks. The HIS 1180mhz draws 239W for roughly 8% more performance over the 1050mhz and that's with only 2048 SPs and 32 ROPs. Don't forget that with 48 ROPs, you'd end up with 192 TMUs. The die size would need to increase substantially from 365mm2 and with it power consumption.
My fear is that if HD8000 series is delayed to Q4 2013/Q1 2014, it might mean 20nm Maxwell/Volcanic Islands could be pushed back. I was hoping they'd launch 1H of 2014.

At the same time until I see next generation PC games, the only thing that keeps upgrades exciting for me is bitcoin mining. Unless AMD releases a 3000 shader card, the bump in bitcoin mining from a 2560SP part will be just 25%, which is nothing special.
"with a 8 RB to 12 Channel mapping there has to be a crossbar somewhere - whether it is from the engine to the RB's or the RB's to the memory channels. You also have to consider how the engine upstream is working and how you tie in RB redundancy as well.
Note, with Tahiti there is not a full RB to memory channel Crossbar - each RB can access just 3 memory channels in order to keep the crossbar complexibility and size down, but still providing some flexibility."
Well if AMD does have a Titan killer they should name it the AMD Zeus.
