About the GTX 1080 Ti
As a recap, the GeForce GTX 1080 Ti is a gaming grade flagship of the GeForce GTX 1000 series. The core uses Pascal architecture based on the 16nm FinFET process and is manufactured by TSMC. The core is labelled as GP102-350. The GTX 1080 Ti uses a 352-bit memory interface and has 3584 CUDA cores, 28 SMMs, 88 ROPs with a TDP rating of 250 watts. The memory size that’s allowed by Nvidia is 11 GB.
Paper Spec difference with the Titan XP…
But why does GTX 1080 Ti have 11 GB while reserving the Titan XP 12 GB with minor differences in core clock, Bus width and ROPs? Its probably done not to piss off the Titan XP users as its MSRP is more than double of GTX 1080 Ti at the time of its release. Would it make any difference on the GTX 1080 Ti? Maybe not!
There was a gap of one month between the reference model and the non-reference GTX 1080 Ti editions. For some, waiting for a month to get something better for the price hardly matters but Nvidia started to compete using its reference design that uses the lateral cooling against non-reference with significant changes in cooling and core clocks. Nvidia’s lateral cooling system needs to be improved upon and not just in the marketing materials.
Why no reference review?
When I asked Nvidia, the official response before its launch was “there is no GTX 1080 Ti. Only the GTX 1080”. A simple “no” would be more respectable. It did not make sense to push the matter further as it showed the company’s unwillingness to send a unit. We have the GTX 1080 Ti AMP! Extreme so we’ll make due with that. A reference comparison would have been nice since I made a couple of additions to the testing workflow.
Minor addition in the review workflow…
The extra added comparisons will provide an interesting insight into computer hardware and would have provided an excellent comparison. With graphics cards, one will generalize non-reference models will be better. But we’re curious to know the amount difference to make a purchase decision. Here is the review of the Zotac GTX 1080 Ti AMP! Extreme- aka the one with the bigger girth!

When you compare the GTX 1080 Ti with the GTX 980 Ti, many of its paper specification have been significantly upped. There are more CUDA cores, SMMS, ROPs, VRAMs, memory bus and bandwidth for the same maximum temperature threshold and same TDP. A comparison between the GTX 1080 Ti and GTX 1080 makes sense because I found it very hard to justify GTX 1080 over the GTX 1070 as its performance felt underwhelming for its price tag. Despite the same architecture, there is a bump in core counts, memory clock, memory size and bandwidth with a higher TDP requirement.

Reference AMP! Extreme Difference Base Clock 1,480 MHz 1645 MHz (165 MHz)
Boost Clock 1,582 MHz 1759 MHz (177 MHz)
The difference in clock speed is a bit more than 11% in base and boost clock. You are getting a good factory overclocked option. As boost clock depends on a lot on the cooling ability of the graphics card, it is easy to assume a non-reference card ( in this case- the AMP! Extreme) will do a better job at providing better performance.

Anyone familiar with Zotac will no they’ll not do a standard size version of the AMP! Extreme. Some might not mind a large card, some may.
