Huawei Honghu 818 SoC vs Mediatek MT5597 vs MT5596 vs Amlogic S905X vs Tegra X1

With the launch of HarmonyOS on the Honor Vision & Vision Pro TVs, I thought it was worth looking into the chipsets that power these devices.

With 4K HDR playback available on most TVs you would expect
something relatively beefy powering the underlying SmartOS. Flagship mobiles
are currently using the 7nm fabrication process, but most TVs and set-top boxes
are using chipsets that are built around a 28nm process, and the Tegra X1 which
is often regarded as the most powerful chipset for Android-based set-top boxes
is manufactured on 20nm process, soon to be upgraded to 16nm.

The new Huawei Honghu 818 SoC also follows suit using that
rather large 28nm process, but it has a specification far higher than chipsets
found on TVs that cost several thousands of pounds.

Its quad-core design uses two ARM Cortex-A72 with two ARM Cortex-A53 combined with a Mali-G51 GPU with a 600MHz clock speed, and 2GB RAM. You might think that this is nothing to get too excited about, but it is sadly much better specced than the competition.

The Nvidia Tegra X1 used in the Nvidia Shield TV has 2x Cortex-A57 + 2x Cortex-A53, though the Maxwell-based 256 core GPU is one of the things that makes it stand head and shoulders above its competition.



The MediaTek MT5596 which is featured in many TVs that run Android including Sony, Philips, TCL, and others. It was used on the Sony AF8 which I own and is listed on the Sony website for £2,299.00 for the 55-inch model. They have a 4K HDR Processor X1 as the picture processor, but it is the MT5597 doing the day to day activities.

The MT5596 is a quad-core 1.1Ghz Arm Cortex-A53 CPU with a
Mali-T860 MP2 built on the 28 nm fabrication process and dates back to 2016.

The MT 5596 supports both HEVC and VP9 Ultra HD codecs and
10-bit video decoder. The SoC can decode Quad Full HD 60 fps video streams
which can be handy if you decide to record multiple channels via a  DVR feature.

This year they have finally updated the chipset to the MT5597 which
still uses the quad-core Arm Cortex-A53 and apparently is lower clocked at
1.0Ghz and uses an unnamed AMR Mali GPU.

It is claimed that this is around 50% faster than the
previous generation, though I struggle to see what it is that generates this
improvement.

The Amlogic S905X which is found on many set-top Android boxes such as the Xiaomi Mi Box uses a Quad-core Cortex-A53 CPU with Mali-450 GPU made on the 28nm fabrication process.

If we look at the Coretex-A72 versus A53. The Cortex-A72
should perform considerably better as it makes use of a 3-way superscalar
instead of the 2 way of A53. It also makes use of out of order execution for
more efficient use of the instruction cycles as the instructions are queued
when the necessary data is unavailable which prevents the stalls which are
generally present at in-order processors due to unavailable data. There have
also been mentions of the improved power efficiency in the A72 due to
improvements in the decode/dispatch stages of the processor.

The Coretex-A72 vs the A57 on the Tegra X1 is actually very
similarly specced, looking at the ARMv8-A cores
on Wikipedia
reveals almost no differences.

A comparison of GPUs is a little harder, in particular, the
Nvidia uses a Maxwell GPU which is much more powerful than many alternatives. This
offers the same features as the laptop and desktop Maxwell-based products like
OpenGL 4.5, CUDA 6.0, OpenGL ES 3.1 and DirectX 11.2. The GPU offers.

256 shader cores (2 SMMs) and clocks at up to 1000 MHz. The
memory interface offers a maximum bandwidth of 25.6 GB/s (2x 32 Bit
LPDDR4-3200). In 3DMark running Ice Storm, this achieved a score of around
56K
.

The Honghu 818 Mali-G51 GPU, it doesn’t state the number of
processors but the Kirin 710 uses ARM Mali-G51 MP4. In 3DMark running Ice Storm,
this achieved a score of around
20K
, so less than half the Maxwell GPU.

The Mali-T860 MP2 on the MT5596 receives just
9.5k
so less than half again.

Overall the Huawei Honghu 818 SoC looks very well specced
for a chipset on a TV costing less than £600.
