NVIDIA's GeForce GTX 560 Ti w/448 Cores: GTX 570 On A Budget
by Ryan Smith on November 29, 2011 9:00 AM ESTPower, Temperature, & Noise
Last but certainly not least is our look at power, temperature, and noise. If we’ve clearly established that the GTX 560-448 has more in common with the GTX 570 than the GTX 560 Ti in gaming performance, then let’s see if the operational attributes are equally close.
| GeForce GTX 500 Series Voltages | ||||
| Ref 580 Load | Ref 570 Load | Zotac 560-448 Load | ||
| 1.037v | 1.025v | 1.000v | ||
Looking quickly at voltage, our Zotac card is set to 1.0v. This is actually 0.025v less than our reference GTX 570 and GTX 580 cards, though it’s important to note that all of these cards have a wide VID range. Realistically speaking we expect that the GTX 560-448 would have a similar to greater VID range than the GTX 570.
It’s quite interesting to find that idle system power consumption is several watts lower than it is with the GTX 570. Truth be told we don’t have a great explanation for this; there’s the obvious difference in coolers, but it’s rare to see a single fan have this kind of an impact.
Power consumption under load shows a similar benefit. With the Zotac GTX 560-448 we’re drawing 15W less than with the reference GTX 570. Given that the performance of the Zotac GTX 560-448 is so close to the GTX 570, and this actually starts looking like a cheaper GTX 570 with lower power consumption, which is not something we would have expected to find. But at the same time this means load power consumption is still nearly 30W greater than the GTX 560 Ti, is a very distinct difference for two products sharing the same name.
FurMark is thrown in for consistency, but at this point NVIDIA’s driver throttling is so extreme that FurMark is instantly beaten back when started.
When it comes to GPU temperatures, idle temperatures straddle the difference between the GTX 560 Ti and the GTX 570. The open-air cooler is usually better for lower temperatures, but at the same time GF110’s higher idle power consumption negates some of this benefit. In any case it’s still one of the coolest high-end cards at idle.
Meanwhile GPU load temperatures are at the middle of the pack. Like all GF110 products the Zotac GTX 560-448 starts getting toasty under load (even with the open-air cooler), but it’s still noticeably cooler than the GTX 570 and GTX 580. With that said the open-air cooler means that this is going to be case-dependent, so cases with poor airflow would favor the closed coolers of the GTX 570 and GTX 580.
Finally we have our look at noise. The Zotac GTX 560-448 idles just a hair louder than most of our other high-end cards, including the GTX 570. Under load however that open-air cooler really makes its mark among a crowd of closed coolers, leading to noise levels little above the GTX 560 Ti and remarkably quieter than the GTX 570. On a performance/noise spectrum this is fantastic, but the devil is in the details: you need a case with good airflow to make this happen. Otherwise the Zotac GTX 560-448 ramps up significantly once temperatures approach 90C.

I can get a 6950 for $200 AR right now. The 560-448 is going in the low $300 range right now.Unless it gets 50% more frames/performance it is not better than a 6950.

For several months now the 2 leading cards in any P/P comparison have been the HD6870 and its HD6850 twin. I just picked one up this month and I'm delighted. As long as consoles won't learn how to upgrade their GPUs, I don't see a necessity for anything above that range of graphics power...Of course, this is an *throws up* enthusiast website, so anyone who's not willing to build a system with at least 2 GPUs, a 1200W power supply and a triple monitor setup, leave the room, we are not interested in you.

The cheapest 1GB HD 6950 on Newegg (who is generally the lowest price on video cards) is $240. The cheapest HD 6950 2GB is $255. You pay that upfront - rebates (if they go well) are months down the road. The GTX 560 448 is about 10% faster. Yes, its the better card.Marlin1975 - Tuesday, November 29, 2011 - link
The cheapest 560-448 I have seen so far is in the low $300 range. I can get a 6950 in the low $200 range.10% more performance for 50% more price is not better.

The image of the GF110 on the first page is wrong it shows 3 deactivated SM units which would make this card a 416 shader part. It should show 2 deactivated SM units for a 448 shader part.Ryan Smith - Tuesday, November 29, 2011 - link
Thanks. You are correct. That will be fixed later today.Per Hansson - Tuesday, November 29, 2011 - link
Hi, what about overclocking?Is this GPU poor at it since it's been binned so hard or is it just that another SM unit where bad while not hindering the clockspeed of the chip?
Ryan Smith - Wednesday, November 30, 2011 - link
I did not have a chance to test overclocking (I only had a single day to test the card). However since NVIDIA is binning chips based on defective SMs, I have no reason to believe that overclocking should be significantly different from the 570.MrSpadge - Tuesday, November 29, 2011 - link
"NVIDIA is purposely introducing namespace collisions, and while they have their reasons I don’t believe them to be good enough."That nails it. Not sure if I should laugh or cry about the current name. They introduced a 3-letter prefix and 3-digit numbers to get rid of the obscure subscripts.. only to reintroduce the "Ti" (why was that one not the GTX565?!) and now this addition to "Ti". Hilarious, if this were a commedy show.
And remind you, just because nVidia did much worse in the past doesn't make this any better...

That is why I DO NOT BUY or SELL nvidia products. This new name proves they are getting dumber by the month. This should be a 570-LE, simple .All these names are stupid since the end of the GeForce 9000 series. While AMD has been mostly good with their names... Mostly. AMD HD 6870, easy.
Gtx vs gt is stupid since they don't make a 550 gt and 550 gtx. TI = totally worthless for a name. If this only atttracts dumb customers, they can keep them.
