While the majority of premium Android phones use Qualcomm's CPUs for the Snapdragon series to power their devices, Samsung is a manufacturer offering a proprietary chip - the Exynos series. This fact only fuels the rumors of a new A series from Samsung, the Galaxy A51.
"The 5G Exynos Modem 5123, one of the first 5G modem chips manufactured using a 7nm EUV process", said Samsung. The Exynos 990 chip also includes on-device AI dual-core neural processing device.
Notably, the Exynos 990 doesn't come with an integrated 5G modem. The new GPU provides an improvement in performance or power efficiency of up to 20% compared to its predecessor. "Samsung will continue to support our smartphone-manufacturing customers with on-time development of next-generation mobile memory solutions, bringing enhanced smartphone experiences to many more users around the globe".
That's right, Samsung also unveiled the Exynos Modem 5123, a 5G chip capable of download speeds of up to 7.35Gbps in mmWave, and 5.1Gbps in sub-6GHz setting with up to 8x carrier aggregation.
In terms of the GPU, Samsung has incorporated the Mali-G77MP11 in the Exynos 990. The Exynos 990 and 5G Exynos Modem 5123 harness the most advanced chipmaking technologies to-date with a 7-nanometer (nm) process using extreme ultraviolet (EUV) lithography. The new processor can support a maximum of six cameras with resolutions up to 108MP (but only three at once at this resolution).
Further, the Exynos 990 gets a dual-core NPU for better on-device AI tasks such as facial recognition and scene detection. At the high end we have support for 5G sub-6GHz and mmWave spectrums with 2G GSM/CDMA, 3G WCDMA, TD-SCDMA, HSPA and 4G LTE connectivity checkboxes ticked too. Screen tearing is reduced, and animations are smoothed out even on "devices with multiple displays, such as foldable phones" via a 20Hz refresh-rate display driver. The Galaxy S11 has already leaked in bits and pieces but Samsung itself may already be providing the bread crumbs that paint the picture of a mighty Next Galaxy that may finally see a long-overdue upgrade in at least one aspect.
The Exynos 990 complements these modem speeds with a very wide memory bandwidth that supports LPDDR5 data rates of up to 5,500 megabits per second (Mb/s).
