First and foremost, when is the radeon 7xxx coming out?
Also, how will they affect difficulty? They're on the 28nm process which means we aren't going to see small efficiency changes, but rather, large scale raw processing increases.

At the moment the only real thing that is known is 28nm manufacturing size. Everything else is just speculation and if you google HD7xxx you'll see there is a lot. One thing is for sure we should see lower temps while working at full load. Smiley

The Radeon 7000/7500 has been around for a while. I have one. Smiley

Don't think those would help with mining though.

^^Lol.


The upcoming HD Radeon 7000 series is said or rumoured to be more computationally competent/efficient.Considering the Cayman architecture was suppose to be .32 nm and AMD/ATI was forced to skip that I'm thinking whatever they couldn't fit on the Cayman architecture will now make a debut with some more improvements.It is also not known if the new card will be the new GCN architecture that AMD was recently showcasing or just a Cayman die shrink with improvements.I'm hoping for 1.2 OpenCl compatibility, more complex shaders and perhaps some Directx 12 upcoming features on the upcoming die considering they have the space.I'm thinking the true next generation core will substantially increase the difficulty considering computations are the focus this time around.

If you believe this post has helped,please donate-

Nvidia's Fermi architecture was supposed to make their cards more computationally adequate. Look how well that turned out. Smiley

Fermi's a beast for computation. Sadly, just not simple stuff like massively paralleled hashing.

Fermi works fine for typical GPGPU work, but not for integer bit twiddling that bitcoin mining does.

The latest I've been able to find on the hd7000 series is that they're slated for a November launch:

A google search for radeon "southern islands" is another way to keep updated.
