NVIDIA's GeForce GTX 560: The Top To Bottom Factory Overclockby Ryan Smith on May 17, 2011 9:00 AM EST
NVIDIA’s GF104 and GF114 GPUs have been a solid success for the company so far. 10 months after GF104 launched the GTX 460 series, NVIDIA has slowly been supplementing and replacing their former $200 king. In January we saw the launch of the GF114 based GTX 560 Ti, which gave us our first look at what a fully enabled GF1x4 GPU could do. However the GTX 560 Ti was positioned above the GTX 460 series in both performance and price, so it was more an addition to their lineup than a replacement for GTX 460.
With each GF11x GPU effectively being a half-step above its GF10x predecessor, NVIDIA’s replacement strategy has been to split a 400 series card’s original market between two GF11x GPUs. For the GTX 460, on the low-end this was partially split off into the GTX 550 Ti, which came fairly close to the GTX 460 768MB’s performance. The GTX 460 1GB has remained in place however, and today NVIDIA is finally starting to change that with the GeForce GTX 560. Based upon the same GF114 GPU as the GTX 560 Ti, the GTX 560 will be the GTX 460 1GB’s eventual high-end successor and NVIDIA’s new $200 card.
|GTX 570||GTX 560 Ti||GTX 560||GTX 460 1GB|
|Texture Address / Filtering||60/60||64/64||56/56||56/56|
|Memory Clock||950MHz (3800MHz data rate) GDDR5||1002Mhz (4008MHz data rate) GDDR5||>=1001Mhz (4004MHz data rate) GDDR5||900Mhz (3.6GHz data rate) GDDR5|
|Memory Bus Width||320-bit||256-bit||256-bit||256-bit|
|FP64||1/8 FP32||1/12 FP32||1/12 FP32||1/12 FP32|
|Manufacturing Process||TSMC 40nm||TSMC 40nm||TSMC 40nm||TSMC 40nm|
The GTX 560 is basically a higher clocked version of the GTX 460 1GB. The GTX 460 used a cut-down configuration of the GF104, and GTX 560 will be doing the same with GF114. As a result both cards have the same 336 SPs, 7 SMs, 32 ROPs, 512KB of L2 cache, and 1GB of GDDR5 on a 256-bit memory bus. In terms of performance the deciding factor between the two will be the clockspeed, and in terms of power consumption the main factors will be a combination of clockspeed, voltage, and GF114’s transistor leakage improvements over GF104. All told, NVIDIA’s base configuration for a GTX 560 puts the card at 810MHz for the core clock and 4004MHz (data rate) for the memory clock, which compared to the reference GTX 460 1GB is 135MHz (20%) faster for the core clock and 404MHz (11%) faster for the memory clock. NVIDIA puts the TDP at 150W, which is 10W under the GTX 460 1GB.
With that said, this launch is going to be more chaotic than usual for an NVIDIA mid-range product launch. While NVIDIA and AMD both encourage their partners to differentiate their mid-range cards based on a number of factors including factory overclocks and the cooler used, these products are always launched alongside a reference card. However for the GTX 560 this is going to be a reference-less launch: NVIDIA is not doing a retail reference design for the GTX 560. This is a fairly common situation for the low-end, where we’ll often test a reference design that never is used for retail cards, but it’s quite unusual to not have a reference design for a mid-range card.
As a result, in lieu of a reference card to refer to we have a bit of chaos in terms of the specs of the cards launching today. As long as you’re willing to spend a bit more in power, GF114 clocks really well, something that we’ve seen in the past on the GTX 560 Ti. This has lead to partners launching a number of factory overclocked GTX 560 Ti cards and few if any reference clocked cards, as the retail market does not have the stringent power requiements of the OEM market. So while OEMs have been using reference clocked cards for the lowest power consumption, most retail cards are overclocked. Here are the clocks we're seeing with the GTX 560 launch lineup.
|GeForce GTX 560 Launch Card List|
|Card||Core Clock||Memory Clock|
|ASUS GeForce GTX 560 Top||925 MHz||4200 MHz|
|ASUS GeForce GTX 560 OC||850 MHz||4200 MHz|
|Palit GeForce GTX 560 SP||900 MHz||4080 MHz|
|MSI GeForce GTX 560 Twin FrozrII OC||870 MHz||4080 MHz|
|Zotac GeForce GTX 560 AMP!||950 MHz||4400 MHz|
|KFA2 GeForce GTX 560 EXOC||900 MHz||4080 MHz|
|Sparkle GeForce GTX 560 Calibre||900 MHz||4488 MHz|
|EVGA GeForce GTX 560 SC||850 MHz||4104 MHz|
|Galaxy GeForce GTX 560 GC||900 MHz||4004 MHz|
This is why NVIDIA has decided to forgo a reference card altogether, and is leaving both card designs and clocks up to their partners. As a result, we expect every GTX 560 we’ll see on the retail market will have some kind of a factory overclock, and all of them will be using a custom design. Clocks will be all over the place, while designs are largely recycled GTX 460/GTX 560 Ti designs. This means we’ll see a variety of cards, but there’s a lack of anything we can point to as a baseline. Reference clocked cards may show up in the market, but even NVIDIA is unsure of it at this time. The list of retail cards that NVIDIA has given us has a range of core clocks between 850MHz and 950MHz, meaning the performance of some of these cards is going to be noticeably different from the others. Our testing methodology has changed some as a result, which we’ll get to in depth in our testing methodology section.
With a wide variety of GTX 560 card designs and clocks, there’s also going to be a variety of prices. The MSRP for the GTX 560 is $199, as NVIDIA’s primary target for this card is the lucrative $200 market. However with factory overclocks in excess of 125MHz, NVIDIA’s partners are also using these cards to fill in the gap between the GTX 560 and the GTX 560 Ti. So the slower 850MHz-900MHz cards will be around $199, while the fastest cards will be closer to $220-$230. Case in point, the card we’re testing today is the ASUS GTX 560 DirectCU II Top, ASUS’s highest clocked card. While their 850MHz OC card will be $199, the Top will be at $219.
For the time being NVIDIA won’t have a ton of competition from AMD right at $200. With the exception of an errant card now and then, Radeon HD 6950 prices are normally $220+; meanwhile Radeon HD 6870 prices are between $170 and $220, with the bulk of those cards being well under $200. So for the slower GTX 560s their closest competition will be factory overclocked 6870s and factory overclocked GTX 460s, the latter of which are expected to persist for at least a few more months. Meanwhile for the faster GTX 560s the competition will be cheap GTX 560 Tis and potentially the 1GB 6950. The mid-range market is still competitive, but for the moment NVIDIA is the only one with a card specifically aligned for $199.
|May 2011 Video Card Prices|

|$320||Radeon HD 6970|

|$180||Radeon HD 6870|
|$160||Radeon HD 6850|
|$150||Radeon HD 6790|
Finally, I’d like to once again make note of the naming choice of a video card. I’m beginning to sound like a broken record here and I know it, but video card naming this last year has been frustrating. NVIDIA has a prefix (GTX), a model number (560), and a suffix (Ti), except when they don’t have a suffix. With the existence of a prefix and a model number, a suffix was already superfluous, but it’s particularly problematic when some cards have a suffix and some don’t. Remember the days of the GeForce 6800 series, and how whenever you wanted to talk about the vanilla 6800, no one could easily tell if you were talking about the series or the non-suffixed card? Well we’re back to those days; GTX 560 is both a series and a specific video card. Suffixes are fine as long as they’re always used, but when they’re not these situations can lead to confusion.

DanNeely - Wednesday, May 18, 2011 - linkWhere exactly are you finding a $300ish 2560x monitor? IIRC even the best sales Dell had on refurb 3007's only dropped as a low as $800ish, and with the potential inventory of off lease 3007's mostly gone by now and the 3008 and 3011's being significantly more expensive deals that good aren't likely to repeat themselves in the future.
L. - Thursday, May 19, 2011 - linkMy mistake you two ;)
I was thinking about a lcd pannel from idunnowho that had 2xyz * something resolution and that was dirt cheap .. obviously 2560*1440 aren't common at all and overpriced.
On the other hand, you could make the argument for a dual monitor setup below 400 bucks that spans more pixels and thus makes more use of the gfx.
Stas - Wednesday, May 18, 2011 - linkYou fail once again. You plan on keeping this card until 20" screens hit 2560x1600/1440? It will probably only be... oh, idk... 10 years?
And $330 for a decent 2560 screen? Links plz.
L. - Thursday, May 19, 2011 - linkYes sir, I would like to be agressive to you to ?
On the other hand ... 10 years ??
My Amoled screen on my n900 has a dpi small enough to cram more than 4*full HD on a 20" pannel, something that will happen soon enough as the oled processes mature.
Again, my mistake on the monitor price, memory error.
L. - Thursday, May 19, 2011 - linkWho would buy a 200 bucks card to play on a single 150 bucks monitor when the whole config costs 700+ bucks ?
200 bucks is A_DECENT_AMOUNT_OF_MONEY for a GFX, it means you're a gamer (maybe a poor one though) and it means you might be interested in dual screen (meh you spent 700 bucks on the tower, why not 2*150 for dual 22" 1080p monitors ?).
L. - Tuesday, May 17, 2011 - linkI'm seeing quite a trend with AMD stuff getting better scores (relatively) on more recent and demanding games, and I'm wondering if it would be time to weight games differently for a better comparison.
For example here, on the important/demanding/modern games (let's take Metro 2033 and Crysis to have undisputable arguments here), the 560 doesn't ever come close to a 6950 and only the best version can beat the 6870 by almost nothing.
If somebody buys a gfx today, it might be to use it for at least another year, and in that sense, the weight of less important games should be diminished a lot, including hawx-120fps-fest, other 100+ fps titles and the clearly nVidia-favoring Civ5.
What is important here, is that NOONE has any interest in buying a gtx560 today, because of the following extremely important points :
-> AMD offerings do better in more demanding games, and will thus do better in future games
-> AMD offerings (6950 for example) have more memory, which WILL be used in next-gen games for sure, as for every gen
-> Noone cares if they have 110 or 120 fps in hawx, which is a console game anyway
I believe the use of any PC component for gamers can be summarized to this in the end :
-> can it play this game ? 30+
-> can it play it well ? 60+
Because any of those components will for most people be used 2 years from now, the fact that older / less-demanding games get 110 fps is completely irrelevant, might as well show 557 fps in quake3 as a benchmark...
As a summary, could you anandtech guys please tweak your test list / weighting in order to better inform the less-informed readers of your website ?
It is utter nonsense to state today that a 560Ti "trades blows" with a 6950 or that a factory OC'd 560 "comes close" to a 6950 either.
The one real true fact is the 6950 gets a huge win in all demanding titles, has 1GB more vRAM and can even unlock+OC very easily to levels none of the 560 versions can reach.
nVidia has done some great stuff in the past, but one has to admit that outside of quad-sli gtx580 there is no use in buying anything nVidia this round, as AMD offers better performance + performance/watt at every price point this time around.
There is one argument for nVidia and that argument (no, not the drivers, because you do NOT play on linux) is the nVidia goodies like 3d gaming and other minor stuff.
crimson117 - Tuesday, May 17, 2011 - linkI half agree with you... some of your commentary is good (HAWX lol) but one particular conclusion is not tenable:
"AMD offerings do better in more demanding games, and will thus do better in future games"
When Mass Effect 3 comes out, I expect that like Mass Effect 2 it will strongly favor nVidia GPU's - unless they rewrote the entire engine.
New games cannot be classified into demanding vs non-demanding - each game engine has its favorite factors, be it clock speed, memory bandwidth, stream processors, ROP's, etc, so I expect each game will have its favorite card.
formulav8 - Tuesday, May 17, 2011 - linkThe thing is, in games that people can actually use the horsepower, the Radeon is the best card.
If you care about getting 500fps on Quake3 instead of 450fps, then the GTX is the better card.
lowlymarine - Tuesday, May 17, 2011 - linkThe problem is that if they DON'T complete rewrite the entire engine, Mass Effect 3 will continue to be a festival of even mid-range cards breaking 60 FPS. While there's nothing wrong with that per se - ME2 is one of the better-looking games out there despite being not particularly intensive, after all - it still means that nVidia's slight advantage over AMD in that game is meaningless. Compare that to Crysis where even the 6970 falls short of 60 FPS at WUXGA, and the sizable lead AMD carries over the competition there has real, noticeable impact on the game.
Stas - Wednesday, May 18, 2011 - linkCorrection:
New games cannot be classified into demanding vs non-demanding - each game engine has its favorite chip developer. Money and politics will decide performance in certain games.
