Continuing with their "Sweet spot" strategy, ATI has launched their mainstream graphics card codenamed Redwood, which comes right on schedule. Today we have with us in the labs the HD5670, which is the fastest of the mainstream cards in the 5600 series. The numbering system of this new card makes one think that it's a replacement for the current hot favourite, the HD4670. However, the folks at ATI have told us that it's actually released to fill the gap between the HD4670 and the HD4770. Therefore, we are looking at possible performance levels of the 9800GT or HD4830.
Another first for ATI and the industry is the incorporation of GDDR5 memory in the HD5670, which is supposed to be a mainstream card. Finally, since this has to appeal to power conscious users who will likely not bother to upgrade their PSU, the TDP is well under 75Watts thereby eliminating the need for an extra 6-pin power connector. Next, let's have a quick look at the specifications below. 
From the specifications, it becomes clearer why ATI have positioned this card above the HD4670. Apart from the faster GDDR5 memory, which gives you almost twice the bandwidth, it also has 80 more shader cores which should by itself help boost the performance. The clock speeds are also bumped up slightly and of course this being a 5xxx series card, we have 40nm fabrication for lower temperatures and DX11 support.
We did not receive any bundle since this was a review sample, but by now you know what to expect.
