PCB Design and Features
The GeForce GTX 780 Ti AMP! Edition is designed in Zotac’s black-and-orange color scheme. The face side of the PCB is covered by a cooler with three fans and metallic casing.
There are vent slits and a silver-yellow name of the manufacturer on the side of the casing. The reverse side of the PCB is exposed. The GeForce GTX 780 Ti AMP! Edition measures 280x100x37 millimeters, which is 13 millimeters longer than the reference GeForce GTX 780 Ti.
Like the reference card, the Zotac has dual-link DVI-I and DVI-D ports, one HDMI 1.4a port, and a DisplayPort 1.2.
There are power and SLI connectors in their conventional locations:
The GeForce GTX 780 Ti AMP! Edition has a specified peak power draw of 250 watts. A 600W PSU is recommended for a computer with one such graphics card. As for SLI support, the GTX 780 Ti can be used even in awfully expensive 4-way SLI configurations.
The PCB copies the reference card's.
The 8-phase power system is based on DrMOS transistors…
…and is managed by an ON Semiconductor NCP4206 controller.
It’s not the first time we see a GK110, yet it keeps on impressing us with its huge size of 561 sq. mm. The GPU is dated the 40th week of 2013 (early October) and, like the GPU of every other GeForce GTX 780 Ti, is the new revision B1.
The 3D frequencies of the card’s GPU are 1006/1072 MHz, which is 14.8% above the clock rates of the reference GeForce GTX 780 Ti. That’s some nice factory overclocking, we must admit. The 2D frequency is 324 MHz. The ASIC quality of our GPU sample is 75.4%:
All of the card’s GDDR5 memory chips are soldered to the face side of the PCB. These are 12 FCBGA-packaged H5GQ2H24AFR-R2C chips from SK Hynix. The total memory amount is 3 gigabytes.
This is the fastest serially manufactured memory from SK Hynix, rated for 7000 MHz at 1.5 volts. Zotac pre-overclocks the chips to 7200 MHz, so the peak bandwidth is as high as 345.6 GB/s across the 384-bit bus. That’s a record-breaking number for off-the-shelf graphics cards.
Here is the summary of the card’s features as reported by the GPU-Z utility:
Now we can proceed to testing its original cooling system.
