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.

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.
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.
Impressive improvement from the current cards.
Another great review from Tom's Hardware. This is the market segment that is most applicable to someone like me.
I thought AMD shifted it's number branding forward for its 6000 series though. These cards should be compared to the 5770 and 5670...? Ahh forget it I'm still confused.

A LOT better!
The HD4550 has just 80 cores and 64-bit DDR3 memory, while the HD6570 has 480 cores and 128-bit GDDR5 memory!
Wow, the 6670 performs like my 5750.

Oops, nevermind. I was looking at the wrong resolution.

They like you confused! This way you'll buy last year's performance in this year's packaging.
If you're going to spend $100, there are a bunch of 5770s on Newegg that will do a better job.
I was surprised not to see 5450s in the mix? They are decent cards for $40 on sale everywhere?

The power draw won't be 1200W or anywhere near it. The overkill with regards to the PSU is to make sure that it doesn't get limited by power and often these test machines are stacked to the max and only certain components are removed. The PSU may be 1200W, but depending on the efficiency (80+%, bronze, silver, gold and platinum) it'll draw exactly what the PC needs from the wall, therefore you can have a very high watt PSU that will actually save you $$ on your power bill compared to the cheapo PSU. Basically, have a 1200W PSU drawing 215W, or 90% accuracy (fill in your own numbers. that's an example).
The videocards are very impressive. Cheap, sip power and perform very well.
Low power consumption on these cards.
Could someone compare these cards to a 512MB 4670? How much better are they? This kind of GPU is perfect for people who don't want to buy new PSUs, don't care about playing the newest AAA commercial games, or run games at low resolutions (like 1366x768), and I'm all three. I would really like to know if it would be a good idea to say goodbye to my 4670 and get one of these.
