I guess people didn't notice me emphasising bitcoin in my comment.
Yes, however let's pick your example and say that AMD would in fact add hardware accelerated SHA256 to their GPU's. I'd rather buy a $300 videocard hashing at 4 Gh/s than a $275 Japaleno in-hand at 7.5 Gh/s (or similar 30 Mh/$ device), even considering the power usage. I can easily sell videocards to gamers

It will perform ~15% better on mining overall. ASICS perform ~500% better than GPUs overall. GPUs have long since become irrelevant in the bitcoin mining world. Even if major manufacturers were to add a specific SHA256 function to GPUs, the fact that the only thing ASICS do is SHA256 means that GPUs will never be relevant in the bitcoin mining world again. GPUs are, afterall, basically designed for graphics...

For bitcoin mining. In litecoin mining they are still great and make much more profit.
and the Hawaii will be even more usefull for scrypt jane (YACoin, YBCoin, ZCCoin, J-Coin, Copperbars, etc.) hashing because it has 4 GB RAM, which means its a smaller hashrate drop with every N factor change than the cards with less memory and CPUs. I will definitely get one.

R9 290X, aka hawaii

The Litecoin mining will be improved by at least 15%, if using 525Kh/s in previous model, Tahiti XT2 @ 925Mhz core

However, There is one more thing which is enigma, How the GCN 2.0 improve the integer generation?

Additionally, The ScryptASIC.org announced the mini on twitter, Which I am still following when available. The consumption for 5Mh/s is within 200W based on the graph as Scrypt operation is discovered using SHA-2 hash XOR with something else to construct the Scrypt(1024,1,1) so the team uses SHA-2 ASIC to generate some hash, then XOR them to generate the Scrypt(1024,1,1) hash. This is just a concept, there will be more applications if successfully shipped.
scryptasic.com 50000 khs for 1500$? yeah right..sounds legit
First of all, it's .org not .com

Second of all, ya it reaks of scam.

They claim to be taking "motherboards parts", converting them with poor photoshopping, adding "stripped down GPUs", adding SHA-256 (REREAD THAT! SHA-256, not scrypt) chips, and then magically getting 50MH/s out of this hackinPC. Bullshit.

So AMD just annunced the new line of GPUs. For bitcoin mining they wont be good compared to ASICs but how about litecoin? What can I expect from the 290X? Hashrates higher than the 7990? What do you think and whats your opinion on the card?
