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

Power, Temperature, And Noise Benchmarks

Before we demonstrate the results of the following tests, it’s important to note that the GeForce GT 240 GDDR5 is not a reference model, but a Gigabyte GV-N240D5-512. Therefore, the results may not reflect typical reference performance.

Let’s start with the power benchmarks:

The new Radeon HD 6670 surprises us by using less power under load than the Radeon HD 5670, despite a higher ALU count and core clock. The GeForce GTS 450 suffers here, consuming significantly more power than competing cards. Note that we're using 3DMark 11 to measure load power, and the DirectX 10-capable GeForce GT 240 is unable to run that benchmark, so we could not capture its results.

GPU temperature is close across the board, with the Radeon HD 6570 suffering the highest levels under load. That's no surprise considering its tiny cooler. The 6670’s larger sink and fan combo is much more capable of dissipating heat effectively.

The GeForce cards perform admirably when it comes to noise output, but all of the Radeons are close behind. Even though the Radeon HD 6570 seems like a gross polluter, the 56 dB result as measured one inch from the fan is hard to notice.

    At a time where most monitors are 1920x1080 putting on top any benchmarks below that resolution is pointless.

    So 30 fps at that resolution in Crysis 2 - not too bad but for me these cards are worthless for any gaming at all. They do not deserve even to be benchmarked and AMD isn't that great in general 2D applications as well.

    I think it is time when GPU designers should think of how to improve and support 1920x1080 as a minimum resolutions. And not just GPU designers but also game developers and OS developers.

    Yeah, some notebooks have lower resolutions but these parts are not notebook parts anyway.

    In the age of CRTs such benchmarks made sense but currently using non-native resolutions on a LCD is ... you know what it is!

    Assuming that every panel ever made has a native res of 1080p... you know what it is! :p

    For cheapo 780p+ (1366*768) and 19" panels (1600*900) these cards are very strong budget performers that require sweet f-all juice to run. And even for 1080p HTPC use they're just the ticket for playing older or less demanding games. So please get off the "Y U NO HD7990??!?" high horse...

    Why is the 5770 listed under test setup but isn't listed anywhere else?
