MediaTek has released a teaser poster, announcing the Helio G90 - their first dedicated gaming chip. The poster doesn't give away much, but it seems that there will be a full reveal soon and as such, there's plenty of speculation to go around.
GSMArena has speculated that the G90 is based on the Helio P90, which has a CPU with two Cortex-A75 cores (2.2GHz) and six A55 cores (2.0GHz). As for the GPU, it’s an Imagination PowerVR GM9446 (970MHz), which promises a 15% improvement over the Mali-G72 MP3 used in the Helio P70.
This means that MediaTek can improve the gaming experience with a gaming mode like the Kirin chips have. In fact, it may be a more powerful GPU in comparison – ARM has the Mali-G76 and G77 graphics cores, Imagination has a new line of Furian flagship GPUs (the GM9446 is a mid-range part from the Rogue family). Right now, Qualcomm‘s Adreno GPUs are considered the best pick for mobile graphics, ahead of ARM and Imagination Technologies.
MediaTek’s chipsets are also traditionally cheaper than Qualcomm’s processors, so it wouldn't be much of a surprise if it aims for the budget sector with the Helio G90. Even so, it's important to note that while gaming phones may be rising in popularity, but a common criticism against them is that they use the same chipsets as non-gaming flagships. With chips like the Helio G90 and Snapdragon 855 Plus, there's definitely more to look forward to than improved cooling and gaming modes.
