The jump to Nvidia’s Pascal and the 16nm node opened up a ton of possibilities for notebook gamers with desktop-class performance on the go for Nvidia’s GTX 1000 Mobile Processors.
With rumours surrounding the GTX 1080’s mobile version in the air for over a month, a leak now points that the desktop and mobile class chip used for the GTX 1060 and GTX 1060M might have very similar performance with a key difference only in clock speeds. This isn’t altogether a revelation for speculators when it comes to the GTX 1000 Mobile chips; most industry insiders essentially are of the opinion that as we shrink nodes over time and GPUs move down the same path that CPUs have, efficiency and lower power draw as well as thermal characteristics of incoming GPU architectures could make the case for comparable performance across the board.
According to a GPU-Z scan outed by Polish website, PurePC, the Nvidia GTX 1060 mobile chip has a GPU Clock of 1405 MHz and a boost clock of 1671 MHz, which when compared to the reference GTX 1060 is less than 10% slower clock for clock. The GTX 1060 comes clocked at 1506 MHz with a GPU boost clock potential of 1709 MHz currently.
Based on the current information we have via leaked specs of both, the GTX 1060 and 1080 mobile, it seems that the mobile versions of both chips will be more or less similar to their desktop counterparts. It is important to note that the GTX 1080 Desktop version has 25% more Texture Mapping Units (TMUs) as per the leak as well as 25% more CUDA Cores (2560 vs 2048) when compared to its leaked mobile version.
|GPU Variant||Core Clock Speed||Boost Clock Speed|
|GTX 1080 Desktop||1607 MHz||1733 MHz|
|GTX 1080 Mobile (Leaked)||1442 MHz||1645 MHz|
|GTX 1060 Desktop||1506 MHz||1709 MHz|
|GTX 1060 Mobile (Leaked)||1405 MHz||1671 MHz|
Purepc benchmarked the mobile GTX 1060 chip with an Intel Core i7-6700K and 16gb of RAM and achieved a 3DMark FireStrike benchmark of 10,295, something that is an impressive feat for what is a midrange gaming chipset aimed for mobile platforms.
It must be noted that while the Pascal architecture has proven to have good thermal characteristics as well as plenty of OC headroom as well as power efficiency to boot, such leaks may not represent the final product. In addition to this, one needs to consider that thermal limitations as well as power draw limitations might still apply resulting in a significant down-clock on various notebooks that are not designed for gaming as a priority. That being said, if the benchmark is correct, with only a ~ 100 MHz core clock gap between the mobile and desktop chip, one could very well argue that there will be a 10% or less performance gap between the GTX 1060 Desktop and Mobile processors. Whether Nvidia is able to replicate this later for the GTX 1080 Mobile is a far more potent question for hard core mobile gamers and professionals on the go.
