MSI N460GTX Cyclone Conclusion

VGA Power Consumption

Life is not as affordable as it used to be, and items such as gasoline, natural gas, and electricity all top the list of resources which have exploded in price over the past few years. Add to this the limit of non-renewable resources compared to current demands, and you can see that the prices are only going to get worse. Planet Earth is needs our help, and needs it badly. With forests becoming barren of vegetation and snow capped poles quickly turning brown, the technology industry has a new attitude towards turning "green". I'll spare you the powerful marketing hype that gets sent from various manufacturers every day, and get right to the point: your computer hasn't been doing much to help save energy... at least up until now. Take a look at the idle clock rates NVIDIA programmed into the BIOS for this GPU. Yes, that's two digits for core and memory clocks, right out of the box; no special power-saving software utilities required.

To measure isolated video card power consumption, I used the Kill-A-Watt EZ (model P4460) power meter made by P3 International. A baseline test is taken without a video card installed inside our computer system, which is allowed to boot into Windows and rest idle at the login screen before power consumption is recorded. Once the baseline reading has been taken, the graphics card is installed and the system is again booted into Windows and left idle at the login screen. Our final loaded power consumption reading is taken with the video card running a stress test using FurMark. Below is a chart with the isolated video card power consumption (not system total) displayed in Watts for each specified test product:

* Results are accurate to within +/- 5W.

The MSI N460GTX Cyclone 1GD5/OC pulled just 18 (140-122) watts at idle and 180 (304-122) watts when running full out, using the test method outlined above. So, there's good news for those who were frightened off by the GF100 power consumption. The GF104 is much more frugal, especially in idle, where the device driver runs the clocks WAY down, without any apparent ill effects. Built on 40nm technology, those two billion transistors could be pulling a lot more power and generating a lot more heat with older chip technology, exactly like the GT200 cards built with 55nm chips did. Next, I'll offer you some final thoughts, and my conclusions. On to the next page...

The fins at the base of the heat-sink spiral in the opposite direction to the fan rotation?

Whoops.

That removes laminar air flow through air friction, and delivers better cooling performance.

# Good Heat TransferBruceBruce 2010-08-11 07:07
For good heat transfer, you basically want the air banging into the surface of the heatsink. Turbulence is good, impingement is even better.

Mini-HDMI is there on the board because of space constraints. You can't put anything else next to 2 DVI's on a single slot bracket.

Favourite benchmarks so far! Uses an almost identical system to me and includes the GTX260 (my current card), great stuff for working out if I want to upgrade yet or not.

FWIW, the Porsche 911 has been water cooled for more than a decade, and the tighter temperature regulation afforded by water cooling led to major increases in power and efficiency (parts could be machined to tighter tolerances since the narrower temperature envelope limited expansion of the parts). Still, for the time, the air cooled 911 was pretty good.

Just think what the engineers could have done with heatpipes...LOL

Seriously, you don't want to get into a discussion of air cooled vs. watercooled Porsches, do you? That's just begging for an invasion of the body-snatchers! Don't you think the comment section has suffered enough lately?

Thanks for the review, very informative! I currently have 2 of these puppies in SLI. I'm curious how the Gainward 2GB version compares with the 1GB versions

# Excellent reviewDr_b_ 2010-08-18 18:53
excellent review. glad you added the older 200 series in for comparison, there doesn't seem to be a reason to keep using the old 285 that i have now. going to SLI two of these.

# It was a great card in its day...BruceBruce 2010-08-18 19:05
I'm sure you got lots of good use out of it, but time and progress marches on. One of the things I like about the GTX 460 cards is that there is a variety of implementations. The ASUS that was reviewd here is another example of a solid non-reference design (4 phase PWM, etc...).

# Question for a purchaseKaelin 2010-08-23 03:58
Thank you for your very interesting article. I must change my graphics card but i hesitate between the MSI N460GTX Cyclone 1GD5/OC and the Asus ENGTX460 DirectCU TOP/2DI/1GD5... I don't know which one to choose =( Which one do you advise ?

(Sorry for my english level)

# Tough Choice...Bruce Bruce 2010-08-23 07:44
They each have larger fans and bigger HSF assemblies that both improve cooling and reduce noise levels. ASUS rolled their own PC board design, and it looks like they increased the PWM from 3-phase to 4-phase. MSI stuck with the reference design. I can't tell where you are located, but you may want to consider the support services that are available in your location, as well as local warranty provisions.

# Asus or MSI...Kaelin 2010-08-23 10:03
Thank you for your reply
I am French so the support service is not a problem (usually)
to help me to decide I would like to know wich graphic card has the cooling system more efficient and wich one has the best resistance to a higher overclocking. And to finish wich one do you prefer ^^

Thanks in advance

# RE: Asus or MSI...sportwarrior 2010-08-24 16:56
I'm also interested in the questions above... it seems that the two cards are quite similar in performance capability, though, so ultimately I'm guessing it doesn't really matter which I would select (I live in SoCal, for what it's worth). I will say I like the look of the ASUS quite a but more than the MSI, but Amazon is making me wait a ridiculously long time to get my card and I NEED to build my new rig very very soon.

Research the warranty support for each, and go from there.

# French Pricing?BruceBruce 2010-08-24 18:47
What are the prices for each, locally? I don't want to say that the two cards are the same, because they are not. But.....they both do an admirable job supporting the GF104 chip, in slightly different ways. I like MSI Afterburner better than ASUS Smart Doctor, so that's how I would go... If the ASUS card supported the ASUS iTracker2 software, it might be a different story.

# The choice is madeKaelin 2010-08-24 23:39
In France, the price difference is about 1 euro for the Asus graphics card. Moreover the Asus ENGTX460 DirectCU TOP/2DI/1GD5 is guaranteed 3 years against 2 for the MSI, that's the reason for why I chose the Asus.

thank you for your help =)

I would have gone with the Asus version too if it had come out earlier as it is $35 cheaper here than the MSI cyclone, both with 3 yr warranty.
