MediaTek Dimensity 9200 Technology Overview

Simply earlier than its Government Summit, which begins at this time, MediaTek introduced its flagship SoC, the Dimensity 9200, the successor of the MediaTek Dimensity 9000. Alongside higher efficiency and enhanced energy effectivity, the brand new chipset brings many “firsts” to the cellular semiconductor trade.

The Dimensity 9200 is the primary chip made with the TSMC 2nd Gen 4nm Course of and to characteristic an Arm Cortex-X3 major core clocked at 3.05 GHz based mostly on the Gen 2 ARMv9 structure.

8 Cores CPU for efficiency and energy effectivity

The guts of this system-on-chip (SoC) is a heterogeneous CPU cluster combining 4 efficiency cores and 4 effectivity cores. The Cortex-X3 (3.05 GHz) and three Cortex-A715 (2.85 GHz) are used for the workload that requires efficiency, whereas the 4 Cortex-A510 (1.8GHz) are chosen by the cluster scheduler and OS thread scheduler to course of much less compute-intensive duties.

As measured by MediaTek utilizing GeekBench 5.0, the single-core efficiency has elevated by 12%, and the multi-core efficiency is 10% higher than the Dimensity 9000. The improved energy effectivity is probably the most spectacular acquire over the earlier era. The brand new chip consumes 25% much less energy regardless of the elevated efficiency.

The CPU cores entry speedy LPDDR5X RAM with as much as 8,533Mbps of bandwidth, an trade first supplied by MediaTek within the Dimensity 9200.

For storing information completely, the UFS 4.0 with Multi Round Queue (MCQ) storage communication protocol gives the quickest information transmission presently accessible for direct entry to storage.

Immortalis-G715, 11 Cores GPU with {hardware} ray tracing

Equally to the Dimensity 9000’s graphics processor Mali G710, the Immortalis-G715 GPU options {hardware} ray tracing (RT).

Now we have not seen particular ray tracing efficiency indicators, however MediaTek’s messaging means that RT could possibly be utilized in 3D video games for primary use instances reminiscent of smooth shadows, reflections, and ambient occlusion.

MediaTek’s GFXBench Manhattan benchmark numbers present that the GPU is 32% quicker than the earlier era whereas utilizing 41% much less energy.

“THE GPU IS 32% FASTER THAN THE PREVIOUS GENERATION WHILE USING 41% LESS POWER.”

Gaming and Viewing Expertise Enhancements

On the gaming aspect, the brand new SoC options MediaTek’s HyperEngine 6.0 Gaming Know-how that mechanically optimizes system settings to make sure most gaming efficiency.

In keeping with MediaTek, the chipset’s MiraVision 890 show expertise intelligently adjusts many show and video stream parameters and offers {hardware} and software program optimizations that enhance viewing high quality.

Moreover, for a greater gaming expertise, the brand new {hardware} helps Full HD+ as much as 240Hz, WHQD as much as 144Hz, and 5K (2.5Kx2) as much as 60Hz, with an adaptive refresh charge.

APU 690, sixth Gen AI Processing Unit

The AI compute unit named APU 690 is the sixth era AI Processing Unit developed by MediaTek.

On paper, the APU 690 ought to carry a 35% efficiency enchancment over the earlier era within the ETHZ 5.0 benchmark and 45% decrease energy consumption for AI-super decision duties (AI-SR).

For instance, if you play a 1080p video saved in your smartphone on a 4K monitor or TV, the APU will assist the graphics system upsample the video with greater high quality. This process is compute-intensive, so it’s nice that MediaTek made it considerably extra energy environment friendly.

The AI structure has been improved from the earlier APU with blended precision. The fifth Gen used the normal integer 16 computing methodology, which signifies that every entire quantity (integer) was all the time encoded with 16 bits. With mixed-precision computing, the APU 690 can now course of each floating level (fractional quantity) and integer (entire quantity) with varied quantity binary codecs, 4 bits, 8 bits, or 16 bits.

For example, 4 bits encode numbers from 0 to 7 while16 bits encoding reaches 65,535. For numbers from 0 to 7 or from 0 to 255, there isn’t any want to make use of the 16 bits format. Permitting the arithmetic models within the {hardware} to function on extra information blocks concurrently (parallelism). MediaTek claims that the introduction of blended precision for the APU 690 boosts the computing pace by 98%.

“MIXED PRECISION BOOSTS THE APU 690’S COMPUTE SPEED BY 98%”

Digital camera options and Imagiq 890 picture sign processor (ISP)

The APU often performs an important position for AI-driven picture segmentation. The GPU and the ISP may take part in that process.

The brand new {hardware} permits real-time detection of picture and video content material to establish the completely different areas of the picture, reminiscent of folks, sky, ocean, buildings, greenery, foreground, and background. As soon as picture segmentation is executed, the system can apply completely different filters or algorithms to the assorted elements of the scene in actual time. It’s used for saturation, shade, and distinction tuning.

AI-driven picture segmentation enhances picture high quality for each the digicam and the show.

MediaTek makes use of AI within the Dimensity 9200 to allow the Twin Stream AI Shutter characteristic, eliminating the blur in motion and sports activities pictures. A characteristic that MediaTek nicknamed “Movement Unblur.”

The Imagiq 890 is the primary RGBW ISP to help the brand new RGBW sensors. Along with the normal RGB pixels, the brand new sensors have white pixels to seize brightness no matter shade. This helps to shoot higher evening footage as MediaTek claims a 30% increase in brightness for evening pictures.

Connectivity

The Dimensity 9200 is the primary SoC to help WiFi 7 with as much as 6.5 Gbps information pace.

The chipset helps mmWave 5G and sub-6GHz connectivity and options mmWave SMART Beamforming which is 25% quicker than common beamforming, based on MediaTek. The brand new mmWave expertise delivers a powerful 7.9 Gbps peak pace for information switch!
