Amlogic S912 vs Amlogic A311D/S922X-B Benchmarks Comparison

A few days ago we compared Amlogic A311D to Rockchip RK3399 since both the top of the line processors from Amlogic and Rockchip that are currently available. Rockchip RK3588 will even be faster, but we need to wait until Q1 2020 at least before it becomes available, and delays are not unheard of, so I’d expect it may take about one year before I can get my hands on a sample.

Another comparison is against Amlogic S912, the previous high-end processor from the company. Amlogic A311D and S922X-B are newer and will be faster but it’s interesting to find out just how much. Note the Amlogic S922X found in ODROID-N2 is clocked at a lower speed compare to A311D/S922X-B, so performance will be somewhat lower. Since I recently benchmarked Khadas VIM3 with Amlogic A311D processor, I decided to dust off my old Khadas VIM2 Amlogic S912 development board, fit it a large heatsink, install the latest Android 7.1 firmware for the board, and run the benchmarks again. You’ll find screenshots of result at the end of this post.

– HDRDolby Vision, HDR10, HDR10+, HLG, and PRIME HDRDolby Vision, HDR10 and HLG

Amlogic S912 is an octa-core processor so people who do not follow the market, may think it will be faster than Amlogic S922X-B hexa-core processor, but the latter comes with more powerful Cortex-A73 cores and Cortex-A53 both clocked at a higher frequency thanks to a 12nm manufacturing processor. The GPU is also more modern with OpenGL ES 3.1 support.

Amlogic S912 was launched at a time when nobody had ever heard of NPU (Neural Processing Unit) in Arm SoCs. Multimedia features are similar, but Amlogic A311D/S922X-B does have support for H.265 encoding, and more HDR (High Dynamic Range) options.

(1) Refinery does not run on Khadas VIM2 / Amlogic S912 since OpenGL ES 3.1 is not supported, and as such the score was 0, while Khadas VIM3 got 17,220 points in the same test. This distorts the results, so I’ve also presented results without Refinery, which give a more realistic view of the performance difference.

Amlogic A311D is way faster than Amlogic S912, about doubling the CPU performance, web browsing scores and so on. I can remember I was disappointed when Amlogic S912 with Mali-T820MP3 was not that much faster compared to Amlogic S905 with Mali-450MP3 GPU in games and benchmarks. But in their latest SoCs, Amlogic did not mess around, provided a proper upgrade with Mali-G52MP4 GPU providing 3 to 4 times 3D graphics performance, and making it suitable as a gaming platform.

So if you have an old Amlogic S912 SBC or TV box and wonder if it’s worth upgrading to Amlogic S922X-B or A311D, don’t hesitate anymore, unless all you do is watching videos in which case the experience should be similar. Amlogic S922X will also provide a significant upgrade over S912, but just a little slower compared to A311D due to the 1.8 GHz maximum CPU frequency.

Since folk have a fascination with the red hot RPI 4, wonder if Amlogic would ever allow over clocking of the s912, s905x, s905w ?
Have Amlogic released the Linux drivers for the G52 GPU yet?

> S912: Octa-core Cortex-A53 @ 1.51 GHz

One cluster is artificially limited to just 1.0 GHz (which can’t be adjusted due to ‘firmware’) so with multi-threaded loads it’s more like eight Cortex A53 at 1.25 GHz. With single-threaded loads it’s even worse since with vendor kernel the scheduler often sends tasks to the slower cluster so in fact S912 with single-threaded loads is often way slower compared to quad core A53 allowed to clock higher than 1 GHz (and this literally applies to every quad core A53 out there).

If the Mali-G52 in those chips is the same as the one in the S922X, then the config should be either mp2 (dual cluster), or mp6, since it’s 2 clusters by 3 engines each. I think mp2 makes more sense, since its purpose is to compare across G52 setups (which come in 3 engines per base config), and not across totally different Malis, IMO.

Most likely a typo, as mp4 cannot translate to 6ee.

After refreshing my memory with Bifrost launch info, arm’s MP officially stands for number of execution engines:comment image
That said, it turns out G52 could come in either 2EE configs or 3EE configs, so mp4 is a possibility, and would signify 4EEs. So mp4(6EE) continues to be a clear contradiction. That said, s922x’s G52 is said to be 6EEs. Which should be easily verifiable /note to self

A s922 MP32 tv box sounds fun

this slide shows MP number equals shader cores count
and in the G52 bifrost architecture, one SC can feature either 2 or 3 EE (execution engine) per shader core
so it doesn’t seem to me that MP “officially” stands for the EE count number, despite amlogic decision to just do that…

i might be wrong, but i also think A311D G52 packs 2 EE per SC (2 SC total), while S922 G52 packs 3 EE per SC (2 SC total)

That’s a possibility. Though if we go by the wording in the official A311D pdf, the use of G52 mp4 vs the use of G52 mp6 is 2:1, so there’s 66% chance of it being 4EE and 33% chance of it being 6EE ; )

It is profoundly strange:

– Beelink’s PR data lists it as an MP6 based on the 6 execution engines
– A311D calls it MP4.

Considering A311D is basically an S922X, id say its confusing as heck.

Same goes for the earlier S905. So many sites called it a pentacore Mali 450 (MP5) but i have also seen MP3.

Stuff like this should have been clear a long time prior.

Besides, Mali T820MP3 obviously is no match considering Mali G31 MP2 out performs it aswell. But i love the coverage of this regardless.

Still that GPU is quite capable, as is T760MP4 in RK3288. We really ought to have more coverage on these – in the beginning of this year it was known that RK3288 would recieved Android 9.0 upgrade. So i am wondering what it can run in terms of modern games. As i recall, RK3288 and Allwinner A80 are the only 2014 SoC’s that would still do really well on modern titles, disregarding more recent SoCS. Especially if you bought one with 4 GB DDR3, you could even run ARK. Imagine buying an UGOOS RK3288 device with 4 GB DDR3 in… Read more »

I wonder about the video encoding capabilities of the A311D/S922X-B and whether it is more of a gimmick than a feature as many more powerful Intel SOC’s can struggle with quick X265 encoding.

I am also curious to know whether they can manage transcoding within TVHeadend PVR recording functionality, which no previous generation of AMlogic SOC was capable of.

Sorry, what? Why would it be a gimmick? They most likely use ARM’s video encoder engines, which is what is most likely used in your smartphone as well (unless you use an Apple device). Can your phone encode H.265 video in real time from the camera? If so, then Amlogic’s chips can encode H.265 video in real time.
Is it going to be comparable in quality to doing it the hard way with multiple CPU cores? No. It’s going to be more similar to Intel’s Quick Sync technology, but this is good enough for most consumers.

S912 costs half what S922X costs so performance is expectly much faster. 28nm + A53 cores were a poor combination but CPU core count was all the rage those days (3 years ago)

Apparently the mainline kernel won’t support video encoding/decoding? http://linux-meson.com/doku.php

I find it frustating that RPi is pretty much the only choice if one wants mainline kernel support for video.

Android PC TV did a comparison with it, and it shows Mali G31 MP2 outperforming Mali T820MP3, albeit not by much: https://androidpctv.com/comparative-amlogic-s905x2-s905y2/

Still, its a huge step up as new common place SoC instead of the overly popular S905/Mali 450 combo.

If you have a s905x 2GB or s905x2 try Real Racing 3, Asphalte ariborne, Freedoom, OpenArena , Dead Trigger and Riptide GP Renegade from Google app store. The age of console gaming on cheap, less then £40.00, TV boxes is here.

Really doubt you’ll be playing anything in a “enjoyable” way on a S905x2/x3 box.
With the S922x yeah,you might get a decent experience(similar to what a entry level Xiaomi Redmi 7(not note 7) phone can deliver these days)BUT at the moment those S922x boxes cost between 90$-120$…Way over 40£ and way overpriced IMO.

He could try them on his s912 but he is busy with reviews and site ect, I would imagine.

Your answer is both wrong and correct. It isn’t really here because gamepad support is flaky, but that can be circumvented. However, in terms of feature set support, console level gaming is definitely a reality with the new low end SoC’s. You gotta understand about mobile GPU’s: Because they have to work with limited bandwidth (and shared with the main memory), mobile GPU’s tend to be rather great at pushing effects, but lack behind in pushing geometry. This is why OpenGLES 2 based titles (which are usually for Mali 400 etc) tend to look like PS2/OG Xbox titles with a… Read more »

Agree that there is gaming potential BUT there is one(or two) more thing you missed… Usually these SOCs have overheating issues and the ones that put together these boxes tend to cut a lot of corners when it comes to materials quality(basically using the cheapest of the cheapest) and don’t spend much (or any) time to make a decent firmware. You mentioned the H6, well as far as I know that’s underclocked because of it’s heating issues,S912 the same story. The new 12nm ones should theoretically be better in that respect but from past experiences Chinese Android boxes don’t perform… Read more »

There are only a few fan cooled boxes out there (That much i do know), but i do know that a lot of these boxes come with passive heatsinks, which is definitely something more than what you have in a phone. Yet another relatively unresearched field – How long can TV boxes cope with gaming before overheating? Indeed, materials are fairly basic (plastic, really) and often enough the board does not even occupy the full space of the enclosure, but that is to be expected when you cater the low end. Its the same kind of industry that makes those… Read more »

I don’t have any of those personally, but those are still rather ”known” titles, don’t you think? 😉 My parents have an S905X based TV box though but they do not game on it. So my only own personal experience is that of my own phone. Fortunately, its exactly the same as an Allwinner H6 (so 4x A53, Mali T720 MP2). It does stuff like PUBG (OpenGLES 3 support!) and Shadowgun Legends aswell as Modern Combat Versus decently. Ofcourse, this is at 720p.

Here is where we need more technical verification like Digital Foundry does:
– What is the common resolution used on TV boxes on these games? Because on tablets/phones, they usually are the screen’s resolution.

– What is the performance in frames, and how long does it sustain?

In the same way that PC and console games are researched, so should TV boxes, and mobile games in general.

I don’t have a PS4, i am not sure what made you say that. 😉
