Today another GTX 700 review, this time we test the GeForce GTX 770 DirectCU II OC 2GB from ASUS. Compared to the GTX 770 reference board, ASUS GTX 770 DC2 OC comes with higher GPU core clock (base clock: 1058MHz, boost clock: 1110MHz) and a stronger power circuitry with a 10-phase VRM (8 phases for the GPU and 2 for the memory).

Here is a comparative table between ASUS’GTX 770 DC2 OC and NVIDIA reference boards (GTX 680, GTX 770 and GTX 780):

GTX 680 GTX 770 GTX 770 DC2 OC GTX 780
GPU GK104 GK104 GK104 GK110
CUDA cores 1536 1536 1536 2304
base clock 1006MHz 1046MHz 1058MHz 837MHz
boost clock 1058MHz 1085MHz 1110MHz 876MHz
ROP 32 32 32 48
TMU 128 128 128 192
Memory bus 256-bit 256-bit 256-bit 384-bit
Memory size 2GB 2GB 2GB 3GB
Memory clock 1058MHz 1753MHz 1753MHz 1502MHz
TDP 195 230 230 250

The bundle: the card, a user’s guide + drivers/utilities and a PCI-E power connector. I already saw better bundles

The backplate brings a mechanical protection as well as additional thermal cooling. Good point for ASUS!

Connectors: two DVI, one HDMI and one DisplayPort:

The GTX 770 requires one 6-pin and one 8-pin power connectors because the TDP of this card is around 230W:

ASUS added additional heatsink the MOSFETs of the VRM

Voltage check points are available for GPU, memory and PLL:

To be sure that you’re ready to take off, ASUS added two LEDs to show that power is OK. This is a recurrent feature in ASUS’ high-end videocards like for this GTX 680 DC2.
