Nvidias’ next generation GTX 1170 and GTX 1180 are rumored/reported with high certainty to be released in the following months. No word on lower tier GPUs – GTX 1160, GTX 1150, etc. It’s been almost two years since the last big update from Nvidia, releasing their Pascal architecture. It’s unclear to me at this point what architecture name these GPUs fall under – “Volta”, “Turing” or maybe even “Ampere”, but the “Turing” sounds more widespread lately.
At its time, Pascal delivered huge performance gains for the same price and power consumption of around +50% compared to the GTX 970M (mobile chip) and around +80-100% for GTX 1050 Ti vs Maxwell I based GTX 960M. It is expected that after so long time, Nvidia will deliver considerable improvements in performance as well.
|GTX 1080||2560 cores, 160 TMUs, 64 ROPs||256-bit, 8GB GDDR5X@10GHZ eff.|
|GTX 1180 (rumored)||3584 cores, 224 TMUs, 64 ROPs||256-bit, 8-16GB GDDR6@12GHZ eff.|
|GTX 1070||1920 cores, 120 TMUs, 64 ROPs||256-bit, 8GB GDDR5@8GHZ eff.|
|GTX 1170 (rumored)||2688 cores, 168 TMUs, 64 ROPs||256-bit, 8-16GB GDDR6@12GHZ eff.|
According to TPU Database for GTX 1170 and 1180, these are 12nm chips based on the “Volta” architecture, and using GDDR6. Also, the GTX 1170 has 2688 shading units, 168 TMUs, 64 ROPs, 21 SMs. The GTX 1180 has 33% more shading units, TMUs and SMs, same ROPs count. This puts the GTX 1170 around or above the current generation Pascal GTX 1080 Ti and the GTX 1180 above the Titan Xp.
Comparing the GTX 1170 raw specs compared to the GTX 1070, the GTX 1170 should have around +40-50% advantage “simply” from the higher cores count, TMUs and clocks. Add to that advancements in architecture efficiency and it should be higher. If the Titan V (Volta) is any measure, then benchmarks over the web (like this) shows performance that is sometimes inline with what you’d expect from the raw specs and sometimes considerably lower, in some games, but the last year Titan V sporadic benchmarks are not a good measure.
The 1100 series rumored to be unveiled on Computex 2018, June with availability starting around July 2018. I was also told around a month ago by a certain Clevo rebrand contact that they will have Nvidia next generation GPUs laptops by the end of 2018 or early 2019.
How much is it interesting? well, I personally think that most people are interested in more midrange GPUs for laptops, like the GTX 1060 that you can find now in $800-$1000 laptops. A +50% performance bump for $1000-$1200 laptops is great, meaning practically all games will run pretty well on 1080p-1440p with highest graphic settings. However, it means that slower CPUs might not be enought o squeeze it all, plus there aren’t many 1440p display offerings right now, and 4K is too much, so a GTX 1160 might be a little waste for casual gaming.
Bottom line, there is stuff to wait for, but there are also questions how it all fits together for the typical up to $1000 gaming laptops ecosystem. We’ll have to wait and see!
