AMD Radeon HD 6670 And 6570: Turkeys Or Turkish Delights?

Radeon HD 6570 GDDR5 And Radeon HD 6670

Both of the reference samples that AMD supplied are half-height models, ideal for HTPC applications. At a casual glance, you wouldn’t be able to tell the Radeon HD 6570 apart from the Radeon HD 6450, despite the huge difference in performance potential. AMD's Radeon HD 6670 stands apart from its peer with a much larger cooler, despite the same 6½” x 3” PCB. It should be noted that this cooler manages to fit within the space designated for a single PCIe slot.

These cards fit within the 75 W limit limit of a second-gen PCI Express slot, and the Radeon HD 6670 becomes the fastest reference design that doesn’t require a dedicated auxiliary connector.

Both reference models have DVI-D, DisplayPort, and analog VGA outputs. The DVI output does support a DVI-to-HDMI adapter for 3D display over HDMI 1.4a. Since the Turks GPU can handle up to four displays, it is possible that some manufacturers will include more outputs on specialty cards, though most are expected to keep costs down with simpler connectivity.

Because the Radeon HD 6570 and 6670 samples share a common PCB, it's no surprise that they're both also equipped with GDDR5 RAM. It’s probable that the DDR3 version of the Radeon HD 6570 has a slightly different arrangement. Be aware of it, though; its performance will be inferior to the GDDR5-based cards being tested today.

    price aside, i'm rather impressed with the 6670. sure the 5750 and gts 450 are more powerful, but nvidia's card just looks ridiculous in the power draw graph. being the fastest card without a pci-e connector is more than just a title, the 6670 will become the new go-to card for people with dells, hps, and ect looking to upgrade to discrete graphics(like the 4670 and 5670 before it).
    also, a 5670 can be found on newegg for $73 before rebate.

    With $99 after MIR 5770s on newegg, the GTS450, 5750, and 6670 are all to expensive. I am most impressed that AMD has got this level of performance out of

    The card has great overclock:

    960Mhz+ / 5000+Mhz for the memory. A 21% increase in games (tpu review).

    i used to play cod4 with a 3.0 ghz dual core and a radeon 4650 @ 1400x900 with good frame rates. and the whole pc only had a draw of 135 watts at the wall. this new 6670 is a kick @ss low power solution for most wanting to game on the semi cheap. kinda want one for my back up pc now.

    For $80, how can you beat a card that can overclock to 6670 speeds easily? And perform identically due to the same specs otherwise?

    ^The 6570, is this card I am referring to.
  • Pengle
    How much better is the 6570 than the 4550

    great review!

    just wondering why we used a 1200w psu when most systems use only 10% of its capacity... i believe the power draw graphs are skewed due to lower efficiency at that load.

    Another gr8 review just loved reading it.

    Its just standard practise to overkill all other components to make sure they don't cause weird results. Besides the absolute draw isn't important its how the cards compare with each other.
