The story of the GTX 1070 Ti
Things have evolved to paint a better picture now that AMD is having an active participation in the CPU and discrete graphics market. AMD Radeon VEGA had its flaws. There are also issue relating its availability and non-reference editions. Regardless, the RX Vega 56 was enough to spook Nvidia. As a result, we see the GTX 1070 Ti.
Competition of any kind is good for the consumers!
While it is placed between two variants, GTX 1070 Ti seems closer towards GTX 1080’s performance. This is why they do not to allow its AIC partners to sell factory overclocked graphics cards. It is based on the Pascal architecture GP104 core using the 16nm FinFET process manufactured by TSMC. Unlike the GTX 1080, the GTX 1070 Ti uses GDDR5 memory chips. Nothing is stopping you from manual overclocking.
There’s a difference in memory which inherits from the GTX 1070. The 8GB GDDR5 works through 256-bit wide memory interface clocked at 8 GHz.
|GTX 1070||GTX 1070 Ti||GTX 1080|
|Core Clock||1506 MHz||1607 MHz||1607 MHz|
|Boost Clock||1683 MHz||1683 MHz||1733 MHz|
|Memory Clock||2002 MHz||2000 MHz||1251 MHz|
|Memory||8 GB, GDDR5, 256-bit||8 GB, GDDR5, 256-bit||8 GB, GDDR5X, 256-bit|
The GTX 1070 Ti has way more Shader units than the GTX 1070 while maintaining the same base clock with the GTX 1080.
About the GTX 1070 Ti AMP! Extreme Edition
This GTX 1070 Ti variant is almost typical of AMP! Extreme editions. The exception is due to Nvidia’s policy of not allowing its AIC partners to have out-of-the-box factory overclocks. The reason is simply to place a space between this and the GTX 1080. While naturally, the GTX 1070 Ti falls between the GTX 1070 and the GTX 1080, the performance is somewhat close to the latter. Many claim its due to Vega’s presence. It would be easier to believe that if VEGA series graphic cards were easily available with its power consumption staying in the similar levels as with the Pascal architecture.
But as many things, there is a workaround! ZOTAC has a downloadable overclock profile and a custom Firestorm utility which loads that preset. It gives a 150 MHz base clock increase and 50 MHz memory clock. You can increase the clock speed further depending on the potential of your card. The ZOTAC GTX 1070 Ti AMP! Extreme edition’s cooling is really well made. But it takes 2.5-slot of space in your case and it is a heavy graphics card where you need to have a support for it. That’s where stands like the one from Cooler Master comes in, but the magnet works only on the steel case.
Zotac has the best possible packaging for graphics cards. It will be required for a heavy 2.5-slot form factor graphic card. You get two braided PCIe connectors and an envelope with only a manual inside. It is difficult to give any accessories when power supplies have all the connection and the card has all the outputs- including the dual DVI-D which GTX 1070 Ti does not provide.

Graphics Card Design
The impressions you would have on the ZOTAC GTX 1070 Ti AMP! Extreme is no different from other typical AMP! Extreme GPUs. It follows the same design and color scheme. The backplate is metal which ‘wraps’ the PCB and has vents to help with heat dissipation.
The triple fan design will blow through six copper heatpipes, the flat copper heat base, the heat fins and the PCB. ZOTAC does have a function where its fans will turn on only when it reaches a certain load. As long as you have enough space below the graphics card with fresh airflow, you’re good to go. As newer architectures are getting more energy efficient, it would be nice to see graphics card manufacturers to keep the mainstream two-slot design.
The GTX 1070 Ti supports SLI. The ZOTAC GTX 1070 Ti AMP! Extreme takes power from a dual eight-PCIe power connector. There’s also an indicator above it to show if it receives power. There’s no way to turn that off. The best for ZOTAC would be to let it indicate improper connector, like how AORUS does it for its graphics cards. ZOTAC provides dual DVI-D to support older display monitors, but it has full-sized DisplayPort and HDMI 2.0b slots.
Ease of Maintenance
Dismantling the card is fairly easy. All you have to do is remove the spring-loaded screw surrounding the core from the back plate. You will need to unclip two wires coming from the GPU cooler. The third wire is for the LED effects on the backplate.
There are a total of eight Micron GDDR5 chips surrounding the chip. The graphics card power delivery is handled via 8+3 chokes. The VRMs has a dedicated heatsink.
