It’s solely been a few weeks since Qualcomm first introduced its new “premium” vary SoC for 2021: the brand new Snapdragon 780G. The chip is a successor to the Snapdragon 765 which ended up being a fairly profitable and standard chip amongst 2020 mid-range and “premium” section units, powering many units resembling for instance the Pixel 5 and 4a 5G.
Also a few weeks in the past, Xiaomi had made a flurry of gadget bulletins among the many Mi 11 Ultra as the brand new mega-flagship gadget for 2021. One gadget we didn’t have time to cowl was the brand new Mi 11 Lite 5G. Beyond the tremendous attention-grabbing form-factor of a 6.8mm thick gadget and weighing in solely 159g regardless of its bigger 160.5 x 75.5mm footprint, in addition to greater high quality OLED show, the telephone differentiated itself by being the very first Snapdragon 780G telephone out there.
We’ve received our arms on a evaluation pattern, and needed to dedicate a bit focusing a bit extra on the SoC, as the brand new chip can be powering not solely the Mi 11 Lite 5G, however undoubtedly a complete lot of different mid-range and premium units within the coming months.

On paper, the brand new Snapdragon 780G is a serious improve from the Snapdragon 765G. The new SoC options not solely upgraded CPU microarchitectures, truly leaping from a Cortex-A76 era to a more moderen Cortex-A78 era, but in addition shifts from a 1+1+four core setup to a 1+3+four setup, which means the brand new SoC has double the quantity of efficiency CPU cores. The clock frequency stays at a peak 2.4GHz for the quickest core within the configuration.
This setup is sort of attention-grabbing because it’s fairly just like the center CPU cores of the Snapdragon 888 flagship SoC, which employs the identical microarchitecture at roughly the identical clocks, and each chips are manufactured on Samsung’s 5nm 5LPE course of node. There are variations within the reminiscence setup because the Snapdragon 780G stays on a LPDDR4X interface that’s solely 2x16b huge, which is smaller than the LPDDR5 4x16b bus that the flagship SoC will get. There’s additionally variations in caches such because the L3 cache being a lot smaller.
CPU Performance & Efficiency
Comparing the efficiency and energy effectivity of the brand new chip in comparison with not solely its predecessor, but in addition its present era flagship sibling, we should always be capable to paint a greater image of how the brand new chip sits within the aggressive panorama.
In SPEC2006, the brand new chip – albeit operating on the similar frequency because the Snapdragon 765G, is showcasing important efficiency leaps…
