MediaTek has introduced two new system-on-a-chips specifically for gamers: the Helio G90 series. The Helio G90 and G90T are composed of ARM's Cortex-A76 and Cortex-A55 for the CPU and Mali-G76 as the GPU and are manufactured in 12 nm FinFET.
The Helio G90T is the faster of the two chips, with MediaTek has not received the changes compared to the normal Helio G90. ComputerBase is in contact with MediaTek on this and other open questions and will update the article as the information becomes available.
MediaTek's Helio G90 series in the area of the CPU consists of an octa-core composite of ARMs Cortex-A76 and Cortex-A55, although it is not known how many cores MediaTek uses per type. Even individual clock data are still pending, it is only known that the maximum clock frequency of a core – presumably a Cortex-A76 – is at 2.05 GHz. MediaTek calls a “great“L3 cache, but without giving details. The system-on-a-chip can handle memory of the LPDDR3 and LPDDR4x versions up to 2,133 MHz and supports up to 10 GB of the latter version. Storage types support eMMC 5.1 and UFS 2.1.
Unknown Mali G76 GPU from ARM
In terms of GPU MediaTek also relies on ARM and uses the Mali G76 with the cryptic name “3EEMC4”, which does not exist in this form in ARM's portfolio. Usually, the number of arithmetic units in ARM is indicated by the designation MPx, for example Mali-G76 MP10 or Mali-G76 MP12. The maximum clock rate of the GPU is indicated by MediaTek for the Helio G90T at 800 MHz. Displays can be addressed with a resolution of up to 2,520 × 1,080 pixels, in the area of video processing H.264 and H.265 / HEVC for encoding as well as H.264, H.265 / HEVC and VP9 for decoding are supported. Resolutions and refresh rates are in both cases 4K with 30 FPS, Full HD with 120 FPS and HD with 240 FPS.
HyperEngine is designed to ensure uninterrupted gaming
Apart from the raw power of CPU and GPU MediaTek advertises with powerful APU (AI processing unit) and the player-oriented HyperEngine, which is to provide various optimizations for mobile play. For example, if the chip detects a deteriorating WLAN signal, LTE can be automatically added. In WLAN there is the possibility to be connected in parallel with 2.4 GHz and 5 GHz with a router. The SoC should also be able to process touch inputs very quickly. When playing, an incoming call can be automatically rejected and the priority of the mobile connection on the game. MediaTek also supports games with HDR10 via the Picture Quality Engine.
Cameras and connectivity
Both Helio G90s are equipped with three Image Signal Processors (ISP), which can process the raw data of a total of up to four cameras. MediaTek names as maximum resolutions 24 and 16 megapixels for a dual camera as well as additional 48 and 64 megapixels for two more sensors. For example, a setup of wide-angle camera with bokeh effect, ultra-wide-angle camera and telephoto camera could be installed, as is currently used on many smartphones.
Connectivity covers MediaTek with LTE Cat. 12 for up to 600 Mbit / s in the downlink and LTE Cat. 13 for up to 150 Mbps in the uplink, Wi-Fi 5 to a / b / g / n / ac, Bluetooth 5.0, an FM radio and the global navigation satellite systems BeiDou, Galileo, GLONASS and GPS.
