ASUS GeForce GTX 770 DirectCU II OC Review
Category : NVIDIA
Published by Marc Büchel on 30.05.13
Today the NDA regarding NVIDIAs new GeForce GTX 770 is ending. In this context ASUS was kind enough to provide us with a custom card and obviously, we've had to check what this thing is actually capable of. The GTX 770 is based on NVIDIA's GK104 chip, which is made from 3.54 billion transistors. In case of the GTX 770 there are eight SMX units activated. Overall one can expect this card to be faster than the GTX 680 and even the price tag should be interesting.

Technical Data / Specifications
With the ASUS GeForce GTX 770 DirectCU II OC you get a card which features a custom PCB as well as a custom cooler. The ASIC quality measured on our sample was 77.7 % which is high considering the average being at 73 % on the cards we had in our hands.
About ASIC quality:
ASUS is using the latest NVIDIA Kepler GK104-425-A2 chip, which is manufactured by TSMC using the latest 28 nanometer process technology. With the GeForce GTX 770 you get eight SMX units which results in 1'536 CUDA cores. Following the specs further, there are 128 TMUs, 32 ROPs, a 256 bit wide memory interface and 2 Gigabyte of GDDR5 memory, which is clocked at 7'000 MHz. In the end there is a memory bandwidth of 224.4 Gigabyte per second. Concerning the GPU's clock speeds it runs at a base clock of 1059 MHz and a boost clock of 1111 MHz. During our tests the highest boost clock we measured was 1149 MHz, which was the same as the average boost clock.
The GTX 770 also supports GPU Boost 2.0. The very first version of GPU Boost stopped overclocking the GPU when a certain power target was hit. This new second version of GPU Boost stops overclocking the card, when a certain temperature is being reached. This makes sense since the temperature is the bigger inhibitor than the power target in most cases. In this case the temperature target is 80 degrees Celsius. In other words, as long as the GPU runs at less than 80°C it will keep overclocking until the maximum frequency has been reached. This is why in our case the average boost clock was 38 MHz higher than the typical boost clock ASUS advertises.

ASUS decided to equip the GeForce GTX 770 DirectCU II OC with their famous DirectCU II cooler. In this case you get three heatpipes which all have a diameter of eight millimeters. Soldered to the heatpipes you find the fin stack which es being provided with fresh air via two fans. Overall this version of the DirectCU II cooler was able to impress. In 2D the fans are inaudble and in 3D the card is still very silent.
A closer look at the PCB shows that ASUS equipped this card with a digital eight phase power design regardin the GPU. When it comes to the memory, you find an analog two phase design. Once more ASUS is using super allow chokes, which provide lower operating temperatures as well as a longer lifespan.
Checking the voltage regulation chip we find a digital multi-phase buck controller ASP1212 from IR (International Rectifier). Furthermore there is an unidentified Richtek 2-phase PWM labelled 02=EL WON taking care of a stable current supply for the the memory.
The memory chips used are made by Samsung and carry the model number K4G20325FD-FC28. They are specified to run at 1'750 MHz (7'000 MHz effective).

Delivery
The card ships well bolstered in a foam made mold. Bundled with the graphics card there is a user guide, a driver CD that includes the overclocking tool GPU Tweak too and a power converter (2x6-Pin-PCIe to 1x8-Pin-PCIe). If you're looking for game vouchers or something like that you'll be disappointed, since there is absolutely nothing like this in the box.

Conclusion
| General | + | - | |
| ASUS’ brand new GeForce GTX 770 DirectCU II OC is a really nice piece of hardware. This custom card is not only quite a bit quicker than the GTX 680 it also comes at a interesting price point and the DirectCU II cooler makes it silent. It's just a pity there there are no games in the bundle when you buy an ASUS OC card these days. Apart from that this thing is excellent. |

| Cooling / Noise Level | + | - | |
| GPU Temperatures were good with a maximum of 80°C under heavy FurMark load with the fans locked at 30 % fan speed. The DirectCU II cooler is really a good and powerful piece of hardware. In Idle the noise level is inaudible, and when there is heavy load applied the fans are still very silent. Overall this custom cooler was able to convince us and we definitely like it. | - inaudible in 2D

| A closer look at overall performance shows that the GTX
770 DirectCU II OC is
9 % faster on average in games than its predecessor, the GTX 680. Taking a look at the clock speed shows that this card clocks at 1149 MHz on average, when applying heavy 3D loads. At this point one can really see GPU Boost 2.0 doing it's job, since it always tries to get the maximum clock speeds out of the card, without overstepping the 80°C temperature target. A closer look at power consumption shows, that our test system, equipped with the GTX 770 DirectCU II OC, burns 59 Watts under idle conditions and 224 Watts under load. Compared to the reference GTX 680 this is only a mere four watts more in both cases. |

| Recommendation / Price | + | - | |
| Should you be looking for a seriously quick graphics card with an excellent cooler, then the GTX 770 DirectCU II OC from ASUS is a great choice. Sure, there is there are faster cards out there but this one even comes with a competitive price tag. In fact, NVIDIA is able to offer more frames per buck then AMD does with the Radeon HD 7970 GHz Edition. | - High-End Gaming | ||
| We gave the GTX 770 DirectCU II OC from ASUS the very good 4.5 out of 5 stars. | |||
