Specs, Efficiency vs Snapdragon 8 Gen 3

MediaTek performed the underdog position for a few years however its current launches confirmed more and more aggressive choices on the cellular SoC area. Its newest processor for Android telephones, the Dimensity 9400, brings the most effective CPU and GPU cores from ARM to struggle for the highest spot within the efficiency (and effectivity) charts. Let’s have a look.

The MediaTek Dimensity 9400 follows the weird format adopted by its predecessor with out the effectivity (small) Cortex-A5x cores in use for greater than 10 years already. For the 2025 season, the Dimensity 9400 brings one Cortex-X925 massive CPU (launched earlier this 12 months by ARM), with three Cortex-X4 CPUs from 2023 (from the identical era as the massive cores on the Dimensity 9300), and 4 Cortex-A720.

Course of node

On the graphics facet, the Dimensity 9400 packs 12 cores of the ARM Immortalis-G925 GPU, maintaining assist for raytracing rendering, and introducing ARM’s tackle rendering super-scaling: ARM Accuracy Tremendous Decision—AASR, to affix the tsunami of rival acronyms: DLSS, FSR, XeSS, GSR, PSSR, and the non acronym MetalFX.

MediaTek calls its implementation HyperEngine Tremendous Decision (HESR, anybody?) however the fundamentals are the identical for all of them: Render a gaming scene at a decrease decision internally to develop it to a better one on-screen, saving on energy and efficiency at the price of some artifacts. For AASR, ARM primarily based its approach on AMD’s FSR2 temporal upscaler, which interpolates pixels primarily based on information gathered from previous frames.

The brand new chip makes use of TSMC’s second-generation 3-nm-class course of node, referred to as N3E. MediaTek is the second firm to publicly announce a consumer-market chip on that node, just a few weeks after Apple’s A18 chips launched with the iPhone 16 line.

Apple is clearly TSMC’s preferential companion, however MediaTek can also be benefiting from its shut relationship with the Taiwanese foundry. Eric Fisher, MediaTek’s Company Vice President, highlighted this throughout a press occasion, noting that the corporate can also be working with different producers like UMC, World Foundries, and Intel Foundry.

In comparison with the earlier era chip—made on TSMC’s N4P course of—, MediaTek advertises a 28% sustained CPU efficiency enchancment (35% on single-threaded duties), or a 40% lower in energy consumption. Equally, the GPU facet guarantees 41% peak efficiency or 44% energy financial savings.

  • Multi: 7304
  • Single: 2239
  • Multi: 6975 
  • Single: 1934
  • Multi: 4467

Take these numbers with some skepticism till third-party opinions go dwell, however not less than they appear believable. For the AnTuTu followers (which Chinese language telephone manufacturers are the largest ones, apparently), MediaTek even gave a 3,000,000 rating for the Dimensity 9400 underneath a “laboratory surroundings” (AKA no thermal constraints).

Talking of constraints, to not be restricted by 2024’s generative AI pattern, MediaTek is touting “agentic AI” as the subsequent “turning level” and was fast to remind us that the Dimensity 9400 is suitable with it. Briefly, agentic AI could be thought-about a function that doesn’t require prompts to behave, utilizing your information and circumstances to autonomously make choices and take actions. Nonetheless, simply as we are actually seeing sensible makes use of of gen-AI, don’t anticipate to see agentic AI anytime quickly.

Fact be informed, lengthy earlier than ChatGPT and Steady Diffusion, cellular chip firms had been already together with AI processing on their chips, however for its Eighth-generation AI core, MediaTek is adopting the NPU title as an alternative of the beforehand used (and complicated) time period “APU”.

Again to sensible enhancements, MediaTek touts an improved Imagiq 1090 picture processor (ISP) with improved zoom each in digital magnification and HDR assist, with a decrease energy utilization whereas recording video. The Dimensity 9400 video processing block now helps 8K60 encoding with HEVC at 8-bit depth, and video decoding provides the identical codec assist because the 9300 predecessor: AVC (h.264), HEVC (h.265), VP9, and AV1.

The Dimensity 9400 is suitable with the newest Bluetooth 5.4 and Wi-Fi 7 requirements, identical to its predecessor. MediaTek, nonetheless, famous that the combo chip makes use of a extra environment friendly course of node, promising 50% decrease energy consumption, improved vary, and even a 25% effectivity enchancment in demanding Wi-Fi hotspot use.

The Dimensity modem now helps the 3GPP Rel-17 customary on the mobile facet. Whereas downlink speeds stay capped at 7 Gbps utilizing solely sub-6GHz bands, as with the earlier era, MediaTek guarantees improved community utilization and decreased energy consumption in real-world situations.

Availability

In response to MediaTek, the primary smartphones powered by the Dimensity 9400 will likely be out there “beginning in This autumn 2024”. So be prepared for upcoming bulletins from the same old manufacturers comparable to Oppo, Vivo, and Xiaomi.

With MediaTek’s main market share within the Android market and the vital design win on the Galaxy Tab S10 sequence, the corporate is forecasting a 50% progress within the flagship SoC marketplace for 2024 compared to 2023.

The strain is now on Qualcomm’s facet on the way it will take care of the Taiwanese problem on the flagship market. With the Snapdragon summit scheduled for later this month, it gained’t be lengthy earlier than now we have that reply.
