Radeon HD 6670 

Released April, 2011
  • 800 MHz
  • 1 GB GDDR5
6.5 Out of 10

Perhaps targeting that segment while maintaining some feature-set cushion with "100% DirectX 11 compliance," AMD is releasing its new Radeon HD 6670 graphics card.

It would have been nice if AMD had used the extra space provided by the 2nd slot for some additional outputs, for example two mini DisplayPort connectors.

Both overclocks are nice, especially the GDDR5 memory with its high-clock potential can help a lot.

What People Are Saying Give it to me straight

Power

Power consumption in all non-3D tests is considerably improved compared to the previous generation.
by techPowerUp! (Apr, 2011)
In 3D the card does its magic without using a lot of power which gives it a leading spot in our performance per watt ranking.
by techPowerUp! (Apr, 2011)
Lower power consumption means less heat which means less fan speed required for ventilation, resulting in less noise.
by techPowerUp! (Apr, 2011)

Performance

In this performance segment DirectX 11 support really doesn't offer much of a benefit, instead of improving performance by using the new API, all developers use it to add eye candy which reduces performance even more.
by techPowerUp! (Apr, 2011)
For just $10 more you can get a HD 5750 and $20 more gets you a HD 5770, both of which offer more performance.
by techPowerUp! (Apr, 2011)
For gaming we saw outstanding performance per watt scores, in 1024x768 no other card is even close to the HD 6670.
by techPowerUp! (Apr, 2011)

Applications

On the other hand, really tiny media PC cases might not even have the space for a dual-slot card.
by techPowerUp! (Apr, 2011)
For an office PC the HD 6670's low power consumption is also useful since it helps with the power bill, which can make a difference when deploying a lot of systems.
by techPowerUp! (Apr, 2011)

Temperature

Given the low power draw, low heat output and low temperatures I see no reason why AMD couldn't have made this card exceedingly quiet which would have attracted low-noise enthusiasts.
by techPowerUp! (Apr, 2011)
Temperatures are low in all tests, given the fan noise I think a better choice would have been a few °C more under load and less fan noise.

Directx

Microsoft's DirectX 11 API has once again elevated the standards of PC game graphics, but is still a new development, as DirectX 9 based self-proclaimed "Blockbuster" titles such as Crysis 2 are being released even today.

Please add Radeon HD 6670 DDR3 (since apparently that's an option)?
Idle power means whole cpu running, not only vga.
help me out here please---im running a GeForce GT530 in a xps 8300. and i want to run dual monitors . one to watch videos and one for regular computing at same time. Dell recomemmended the radeon hd 4350 or 6350 . but thats downgrading to me--by research---not a comp geek but --i need to find answers- thanks---kinda all new to me
Idle: 106W WTF?!
