Returning home on Monday, I was greeted by several (slightly wet) boxes from Asus. Happily, the rainstorm that made these boxes a bit damp did not last long, and the wetness was only superficial. The contents were perfectly fine. I was pleased by this, but not particularly pleased with FedEx for leaving them in a spot where they got wet. All complaints aside, I was obviously ecstatic to get the boxes.
Quite the lineup. The new packaging is sharp looking and clearly defines the contents.
Inside these boxes are some of the latest and greatest video cards from Asus. Having just finished up a budget roundup, I had the bandwidth available to tackle a much more complex task. Asus sent four cards for our testing procedures, and I intend to go over them with a fine toothed comb.
The smallest of the bunch is the new GTX 670 DC Mini. Asus did some serious custom work to not only get the card as small as it is, but also to redesign the power delivery system so that the chip only requires a single 8 pin PCI-E power connection. Most GTX 670 boards require 2 x 6 pin connectors which would come out to be around 225 watts delivered, but a single 8 pin would give around 175 watts total. This is skirting the edge of the official draw for the GTX 670, but with the GK104 chip being as mature as it is, there is some extra leeway involved. The cooler is quite compact and apparently pretty quiet. This is aimed at the small form factor crowd who do not want/need a overly large card, but still require a lot of performance. While the GTX 700 series is now hitting the streets, there is still a market for this particular card. Oh, and it is also overclocked for good measure!
We see a nice progression from big to little. It is amazing how small the GTX 670 DC Mini is compared to the rest, and it will be quite interesting to see how it compares to the GTX 760 in testing.
The second card is the newly released GTX 760 DCII OC. This is again based on the tried and true GK104 chip, but has several units disabled. It has 1152 CUDA cores, but retains the same number of ROPS as the fully enabled chips. It also features the full 256 bit memory bus running at 6 Gbps. It has plenty of bandwidth to provide the card in most circumstances considering the amount of functional units enabled. The cooler is one of the new DirectCU II designs and is a nice upgrade in both functionality and looks from the previous DCII models. It is a smaller card than one would expect, but that comes from the need to simplify the card and not overbuild it like the higher priced 770 and 780 cards. As I have mentioned before, I really like the budget and midrange cards. This should be a really fascinating card to test.
The next card is a bit of an odd bird. The GTX 770 DCII OC is essentially a slightly higher clocked GTX 680 from yesteryear. One of the big changes is that this particular model foregoes the triple slot cooler of the previous generation and implements a dual slot cooler that is quite heavy and with a good fin density. It features six pin and eight pin power connections so it has some legs for overclocking. The back plate is there for stability and protection, and it gives the board a very nice, solid feel. Asus added two LEDs by the power connections which show if the card is receiving power or not. This is nice, as the fans on this card are very silent in most situations. Nobody wants to unplug a video card that is powered up. It retains the previous generation DCII styling, but the cooler performance is certainly nothing to sneeze at. It also is less expensive than the previous GTX 680, but is faster.
All of the cards sport dual DVI, DisplayPort, and HDMI outputs. Both DVI ports are dual-link, but only one is DVI-I which can also output a VGA signal with the proper adapter.
Finally we have the big daddy of the GTX 700 series. The 780 DCII OC is pretty much a monster card that exceeds every other offering out there, except the $1K GTX Titan. It is a slightly cut down chip as compared to the mighty Titan, but it still packs in 2304 CUDA cores. It retains the 384 bit memory bus and runs at a brisk 6 Gbps for a whopping 288.4 GB/sec of bandwidth. The core is overclocked to a base of 889 MHz and boosts up to 941 MHz. The cooler on this is massive. It features a brand new fan design for the front unit which apparently can really move the air and do so quietly. Oddly enough, this fan made its debut appearance on the aforementioned GTX 670 DC Mini. The PCB on the GTX 780 DCII OC is non-reference. It features a new power delivery system that should keep this board humming when overclocked. Asus has done their usual magic in pairing the design with high quality components which should ensure a long lifespan for this pretty expensive board.
I do like the protective plates on the backs of the bigger cards, but the rear portion of the two smaller cards are interesting as well. We will delve more into the "Direct Power" functionality in the full review.
I am already well into testing these units and hope to have the full roundup late next week. These are really neat cards and any consumer looking to buy a new one should certainly check out the review once it is complete.
Asus has gone past the "Superpipe" stage with the GTX 780. That is a 10 mm heatpipe we are seeing. All of the DCII series coolers are robust, and even the DC Mini can dissipate a lot of heat.

As promised [H]ard|OCP has spent some time overclocking the ASUS GTX 660 DirectCU II card and have come back with their results. The highest GPU clock they managed was a reported 1170MHz Boost clock in GPU Tweak but which was 1215MHz in actual in-game performance. While that was the high speed record it did not provide the best performance as the frequency often dipped much lower because of the heat produced, [H]'s sweet spot was actually a 1100MHz Boost clock, in-game a much more steady 1152MHz though it did still dip occasionally. They also upped the memory, but again because of the heat produced by the overclock they could not raise voltage without negative consequences. Check the whole review here.
"We put our new ASUS GeForce GTX 660 through the ringer of overclocking and make real world gaming comparisons. If you are thinking the new GTX 660 (GK106) GPU will be a good overclocker like its bigger brother GK104, you may be in for a surprise that puts the new GTX 660 in a new light."

ASUS' family of DirectCU II TOP have made a good name for themselves with enthusiasts, coming from the factory with impressive overclocks and a quiet and efficient custom cooler. There is a new member of this family, the GTX670 which comes with a default clock of 1059MHz and a boost clock of 1137MHz though the memory remains unchanged at 6GHz. These cards have more than just a custom cooler, the capacitors and switches are significantly better than the ones found on other cards which gives the card a longer lifespan as well as giving it serious overclocking headroom which you can see in action in [H]ard|OCP's review. At $430 it does cost a bit more than the stock version, but not prohibitively so.
"ASUS has delivered the fastest GeForce GTX 670 on the market in the ASUS GeForce GTX 670 DirectCU II TOP video card. The monster overclock and the improved cooling system are sure to provide the performance we yearn for. We will be testing it in the recently released Max Payne 3 against a GeForce GTX 680 and Radeon HD 7950."

AMD Gets the Direct CU Treatment
In the previous roundup I covered the DirectCU II models from Asus featuring NVIDIA based chips. These boards included the GTX 580, 570, and 560 products. All of these were DirectCU II based with all the updated features that are included as compared to the original DirectCU products. With the AMD parts Asus has split the top four products into two categories; DirectCU II and the original DirectCU. When we start looking at thermal properties and price points, we will see why Asus took this route.
AMD has had a strong couple of years with their graphics chips. While they were not able to take the single GPU performance crown in this previous generation, their products were very capable and competitive across the board and at every price point. In fact, there are some features that these cards have at particular price points that make them very desirable in quite a few applications. In particular are the 2 GB of memory on the HD 6900 series cards where the competition from NVIDIA at those price points features 1 GB and 1.25 GB. In titles such as Skyrim, with the HD texture DLC enabled, these cards start to limit performance at 1920x1080 and above due to the memory requirements needed for these higher resolution textures.
3 NV for DCII
The world of video cards is a much changed place over the past few years. Where once we saw only “sticker versions” of cards mass produced by a handful of manufacturers, we are now seeing some really nice differentiation from the major manufacturers. While the first iterations of these new cards are typically mass produced by NVIDIA or AMD and then distributed to their partners for initial sales, these manufacturers are now more consistently getting their own unique versions out to retail in record time. MSI was one of the first to put out their own unique designs, but now we are seeing Asus becoming much more aggressive with products of their own.
The DirectCU II line is Asus’ response to the growing number of original designs from other manufacturers. The easiest way to categorize these designs is that they straddle nicely the very high end and extreme products like the MSI Lightning series and those of the reference design boards with standard cooling. These are unique designs that integrate features and cooling solutions that are well above that of reference cards.
DirectCU II applies primarily to the cooling solutions on these boards. The copper heatipipes in the DirectCU II cooler are in direct contact with the GPU. These heatpipes then are distributed through two separate aluminum fin arrays, each with their own fan. So each card has either a dual slot or triple slot cooling solution with two 80 mm fans that dynamically adjust to the temperature of the chip. The second part of this is branded “Super Alloy Power” in which Asus has upgraded most of the electrical components on the board to match higher specifications. Hi-C caps, proadlizers, polymer caps, and higher quality chokes round out the upgraded components which should translate into more stable overclocked performance and a longer lifespan.
