That new AMD graphics cards would come out on April 19 was made certain a while ago and, sure enough, the Sunnyvale, California-based company has delivered the Radeon HD 6570 and 6670.

The mainstream market may have had the Radeon HD 6700 and 6800 series of graphics adapters, but there was still room for more affordable cards.

The low-end market got the Radeon HD 6450 a while ago, and with that, in itself, being a fairly late release, it was about time these two others came out.

The Radeon HD 6570 and 6670 will replace the 5570 and 5670, respectively, featuring a higher number of Stream Processors and higher clock speeds, among other things.

What they share with their previous-generation counterparts is the frequency at which the VRAM works, that being 1 GHz (4 GHz data rate GDDR5), the interface of 128 bits and the ROP count of 8.

Speaking of memory, the HD 6670 has 1 GB (5670 could have 512 MB as well), while the 6570 boasts 512 MB of its own (5570 had 1 GB).

For those interested in exactly what they can expect, reviews of the adapters have already been published by the likes of AnandTech and HotHardware.

Overall, with the 480 Stream Processors (each) and the transistor count of 716M, they are more powerful than the Radeon HD 6450, as well as more expensive.

Of course, being mainstream-level and not low-end boards, this was more than expected. Nevertheless, the actual prices are still well within affordable ranges for the bulk of the consumer market.

The Radeon HD 6570 (GPU clock of 650 MHz), as the less mighty of the two, should show up online, if it hasn't already, for the price of $79, while the HD 6670 (800 MHz) sells for $99.

Both controllers have a low profile construction and a low power draw (60W and 66W, respectively).
