Mediatek presents the first 4 nanometer processor


Taiwan-based Mediatek has now officially presented the new system circuit Dimensity 9000, the world’s first production-ready 5G circuit built with 4 nm technology. The processor uses a Cortex-X2 at 3.05 GHz together with three Cortex-A710 at 2.85Ghz and four Cortex A510 at 1.8Ghz.

Dimensity 9000 also has 14 megabytes of cache, which according to Mediatek improves performance by 7 percent and bandwidth by 25 percent compared to using eight megabytes of cache.

The graphics utilize a brand new Mali-G710 GPU with ten cores and they have also released development tools that enable raytracing. LPDDR5x memory is also supported at speeds up to 7500Mbps.

Dimensity 9000 is also the first to use Bluetooth 5.3, and supports Wi-Fi 6E 2×2 and Beidou III-B1C GNSS for positioning.

The signal processor has the theoretical performance of being able to record 4K HDR video from three cameras simultaneously, and by going through three individual ISPs (Image Signal Processor) it becomes possible to record 18-bit 4K HDR video at 270 frames / second. For standard shooting, the Dimensity 9000 supports camera sensors up to 320MP.

The 5G modem will not support mmWave, but sub-6Ghz 5G with a theoretical download speed of 7 Gbps with 3CC Carrier Aggregation (300Mhz). It is also currently the only 5G modem with support for R16 UL Tx Switching for both SUL and NR UL-CA based connections.

Mediatek says that the first mobiles to use Dimensity 9000 will appear towards the end of the first quarter of 2022.
