PCB Design and Features

Although the Gigabyte GeForce GTX Titan Black GHz Edition is shipped with an alternative cooling system, it comes as an ordinary reference GeForce GTX Titan Black.

The logo on the cooler’s casing and the information on the sticker on the reverse side of the PCB are the only indications that it is a product from Gigabyte.

The Gigabyte GeForce GTX Titan Black GHz Edition has a standard selection of video outputs including dual-link DVI-I and DVI-D connectors, one HDMI 1.4a and one DisplayPort 1.2. There’s also a vent grid in the card’s mounting bracket to exhaust the hot air out of the computer case.

Like a regular GeForce GTX Titan Black, the Gigabyte version has one 8-pin and one 6-pin power connector. There are no differences in terms of the SLI connectors, either.

Notwithstanding the increased GPU clock rate, the graphics card is specified to need up to 250 watts of power and is recommended to be used with a 600-watt or higher power supply.

Beneath the default cooler we found a copy of the reference PCB of the GeForce GTX Titan Black/Titan/780 Ti models.

Here is 8-phase GPU power system with DrMOS transistors.

The GPU voltage regulator is based on an ON Semiconductor NCP4206 controller.

Manufactured on the 47th week of 2013 (in the middle of November), the GPU is somewhat older than the Zotac’s but is the newest B1 revision, too.

We don’t know if some special GPU samples are selected for this graphics card, but its base 3D clock rate is set as high as 1006 MHz, which is 13.2% higher than the clock rate of the reference GeForce GTX Titan Black. And its boost clock rate is 1111 MHz! That’s impressive and even risky factory overclocking, yet it makes the card the fastest single-GPU solution on the market. The ASIC quality of the GPU isn’t very high at only 72.1%.

It proves again that there’s no correlation between ASIC quality and frequency potential.

Like a regular Titan, the card carries 6 gigabytes of GDDR5 memory - in 12 chips from SK Hynix (H5GQ2H24AFR-R2C).

The memory chips are rated and clocked at 7000 MHz, so there is no factory overclocking here. It may be a downside in terms of marketing because even an extra 200 MHz to the memory frequency would have made the card even more attractive in the user’s eyes. But if we talk about performance, memory overclocking doesn’t provide tangible benefits for Nvidia-based products of this class.

Here’s a summary of the Gigabyte GeForce GTX Titan Black GHz Edition specs from the GPU-Z utility.

Like all reference GeForce GTX Titan Black products, the graphics card comes with two BIOS chips.
