Rockchip RK3399 Benchmarks Appear on GeekBench

Rockchip RK3399 hexa-core processor with ARM Cortex A72 and A53 cores and a Mali-T860MP GPU will soon be found in TV boxes, development boards, tablets, Chromebooks, virtual reality headset and more, and is widely expected to offer a significant performance boost against previous Rockchip processors, including RK3288, and outperform SoCs from competitors like Amlogic and Allwinner.

We can have a first clue about the performance as Rockchip RK3399 boxes and one tablet are now showing up on GeekBench.

rk3399-benchmarks

The box is clocked at 1512 MHz, while the tablet is limited to 1416 MHz, but overall single-core score is about 1350 points, while multi-core score hovers around 2,550 points. I’m not that familiar with GeekBench so number don’t tell me anything. Let’s compare it against RK3288 which CPU-wise is the fastest processor I known of from Chinese silicon vendors targeting TV boxes.

rk3399-vs-rk3288There’s a significant single-core performance boost (+73%), and lower multi-core delta (+30%) as expected since RK3399 has 2 fast Cortex A72 cores, 4 low power Cortex-A53 cores, against 4 fast Cortex-A17 cores for RK3288. If you look into the details AES is over 10 times faster on RK3399, so there must be some special instructions used here, or AES hardware acceleration.

Rockchip RK3399 “reference” TV box also has 4GB RAM, so I’m expecting RK3399 devices to come with 2 and 4 GB versions.

RK3399 vs Tegra K1
RK3399 vs Tegra K1

Rockchip RK3399 is also faster than Nvidia Tegra K1 quad core Cortex A15 @ 2.2 GHz for single thread performance, and about equivalent for multi-core tests.

[Update: I also found GFXBench 3D graphics results for RK3399, and compared it to Nvidia Tegra K1.

rk3399-gpu-benchmarkThe Mali-T860MP used in RK3399 is still far from the performance delivered by the Kepler GPU in Tegra K1.

Now if I compare the results to RK3288 (Mali-T764 GPU) based Ugoos UT3s TV box, the score on RK3399 (Mali-T860MP4) is also lower.

rk3399-vs-rk3288-gpuWe’ll have to wait and see here, as we don’t know at which frequency the GPU is running. Both GPUs are supposed to have the same performance according to Wikipedia.]

Nice to see how a dual-core A72 is able to perform (count of cores used can be seen when comparing single and multi threaded Geekbench results)

That’s very impressive, but I expect the multicore score to improve somewhat with time.

2K for multicore is what the current crop of RK3368 achieves.

I’ll be taking a look at the compute scores, that’s where you’ll probably see a significant gain in performance.

@shomari How should ‘multicore score’ improve? Geekbench is just a dumb passive benchmark and simply runs single or multi threaded. It depends on the kernel and active settings what happens then (and of course switching to the quad-core A53 cluster would improve numbers). What does Geekbench numbers tell then? Not that much as usual 🙂 But people love comparing numbers even if they’ve no meaning at all (since it’s so easy). Still true: Passive benchmarking is in 99.x% of the times just ‘benchmarking gone wrong’ 🙂 Those Geekbench numbers could be used to dig deeper into a) how to improve… Read more »

My comment was more in relation to the contrast between the current A53 and the RK3399.

Configuration is a big deal with this kind of benchmark. The results measure settings and even environments more than they validate hardware performance. There’s no telling what was really being tested when a user launched/executed the benchmark just by looking at the number itself.

What’s going on here?

Passive benchmarking gone wrong? Just another quick&dirty Android benchmark measuring software/settings and claiming to test hardware instead? 🙂

Unfortunately that does not only apply to Android but to the other platforms Geekbench ‘supports’ too (we had a customer buying outdated Macs a few years ago based on moronic ‘Multi Core’ Geekbench scores that were absolutely irrelevant. They paid a lot more money to get the slower machines thanks to ‘benchmarking gone wrong’)

@shomari Please look at these Pine64 results: https://browser.primatelabs.com/geekbench3/search?q=a64 A benchmark that hides throttling and even killed CPU cores is bad. There are results collected with only 3, 2 or even 1 active CPU cores without warning the clueless target audience that something’s wrong. And then people start to draw the wrong conclusions (like ‘Android 7.0 is faster than Android 5.1 on Pine64’ while in reality the community Android builds simply rely on community and not vendor settings — that’s dvfs / cpufreq scaling and improved throttling settings). And obviously something similar happens when ‘benchmarking’ Tegra X1 where for whatever reasons… Read more »

Do the RK3288 and RK3399 both have the same number of copies of the GPU? RK3399 might have two, and RK3288 has four? That would explain the 2:1 performance difference.

@Jon Smirl
RK3399 has Mali-T864, RK3288 has Mali-T764, Geekbench score is CPU only here and seems to use the 2xA72 cluster exclusively?

Jon Smirl

@tkaiser
I see this: RK3399 has Mali-T864, RK3288 has Mali-T764. But you can put down between one and four shader units with those GPUs. Did both chips put down the same number of shader units on the chip? A T-864 shader may be equal to the T764 one, but if one chip has four copies and the other only has two, performance is not equal.

Tarwin

They supposedly both use MP4 (quad core) configurations.
We also have to remember that early builds are often not optimized and sometimes even run at slower speeds.
I’m guessing/hoping that performance is equal, possibly slightly better on more advanced stuff (due to generational advances) on the new SoC.

As for AES, from what I understand ARMv8 has built-in support for it while v7 doesn’t (which supposedly even has to do with some mainstream devices not supporting upgrades).

Good point @Tarwin, that early units are not optimized and may run slower. That’s my new default statement on STB’s, as demonstrated by S905 ( nevermind the A,X,912 units) though comparing Rockchip and Amlogic is not really an accurate comparison.

Might be true but this Geekbench ‘single vs multi core’ non-sense is only about CPU (cores) — see the Pine64 numbers above (there are numbers where Allwinner’s weird ‘kill CPU cores instead of throttling’ settings combined with overheating before led to A64 running on a single CPU core any more and then single and multi core scores are identical)

If RockChip deliver on the promised I/O capabilities, RK3399 will be an outstanding allrounder. If they can also deliver on the promised 2 GHz capability for A72 and A53 cores then RK3399 may be able to dominate the market in the way that RK3188 did a few years ago.

Except the promotional material only said “up to 2ghz” and never said if it applied to both core clusters. It could be only for the 72s or only the 53s with the other one being a shower frequency (I hope it’s not the case but I’m hedging my bets).

Can someone explain why the cluster of 4 cortex A53 cores from Nvidia is faster than the same cluster but from Allwinner ? Also, I use geekbench every day and sometimes it doesn’t make sense, so I can see what you mean by dead cores. For example, why does RK3399 have similar performance to Tegra K1, it has two cortex A72 cores and a cluster of Cortex A53, yet on Geekbench it has similar score for multicore, but higher for single but yet again why is does a more modern hexa core CPU have similar scores to an old quad… Read more »

A64 on Pine64 runs with 1152 MHz max (not 1.34 GHz as reported by this Geekbench thingie) and as long as Allwinner’s original (bad) settings are used on boards without heatsink chances are great that it’s not a quad-core SoC but just one with 3, 2 or even 1 active cores any more (the default cpufreq scaling is also pretty bad so as soon as throttling gets an issue A64 will perform pretty bad).

I just ran GeekBench on Xiaomi Box 3 Enhanced CPU Mediatek MT8693 same architecture RK3399 (2xA72 and 4xA53) with single core about 1559 and multi core about 3064, all higher than RK3399. I also ran GFXbench and score is higher than RK3399 with 250.7 vs 236.9

@hoangdinh86 Then Geekbench is showing that MT8693 is also just a dual-core SoC when we’re talking about CPU performance? 😉 BTW: It gets even more funny when looking at so called deca-core SoCs like Mediatek’s X20: https://browser.primatelabs.com/v4/cpu/search?q=mt6797 Obviously the benchmark sometimes runs on the 2xA72 cluster, sometimes on the slow and sometimes on the faster 4xA53 cluster and the kernel switches between the 3 clusters at runtime sometimes (maybe based on thermal/throttling behaviour?). Without continually monitoring both actual cpufreqs and reported SoC temperature this is just the usual and useless ‘fire and forget benchmark’ crap producing random numbers. But people… Read more »

… you’re making really good points here, as usual. This discussion has spurred me to continue with my once abandoned project to enable ‘true’ octacore processing, allowing mulithreading among all cores of the RK3368. So far, I’ve disabled all throttling and lowered the vcore as a compensation at the risk of impacting stability. I’m experimenting with allowing individual cores to sleep as another method of power management … but the main task for now is to eliminate segfaults and async errors and finally accomplish true multithreading in order to gauge just what this architecture on RK3368 can do. Because as… Read more »

The differences are caused because these are not like for like comparisons.

Think of it as one race track, and three, 1.2 Litre cars,

A Ford

A Vauxhall

A Fiat

They are all petrol cars, they all use combustion engines and all use tyres. However design difference mean they don’t all finish first or handle the same.

@paul taraneh The problem with people scared about low ‘multi core’ performance numbers is that they don’t want to understand what these deca-core and hexa-core implementations are in reality. None of the big.LITTLE implementations here is using HMP: Heterogeneous multi-processing (global task scheduling), they’re all just a bunch of independent CPU clusters that work either/or. So RK3399 is either dual or quad core as is Mediatek’s ‘deca-core’ X20 too for example. This one is not really deca-core but dual-core when it’s about ‘high performance’ and quad-core when the device is idling around or starts to overheat (this is something that… Read more »

.. that last bit about switching to HMP is a real problem, I’ve been having plenty of these errors and segfaults trying to bring up an octacore in this fashion.

For the record, HMP has been working more or less ok on the RK3368, but that’s not as ‘heterogeneous’ (both big and LITTLE being A53, difference being in clocks and cache sizes) as RK3399, so your HMP mileage with the latter may vary.

shomari

I brought up all eight cores on the RK3368 as well; scaling, latency and clocks are uniform across all cores using GTS. Antutu completes and shows significant performance gains but unfortunately GeekBench segfaults once multi threading kicks in.

@blu Nice, I searched for ‘RK3368’ on my local machine (Spotlight in OS X) just to discover that I bought a device with it 10 months ago. Now searching for the GeekBox (physically — no search engine involved 😉 ) to do some testing the next days 🙂 BTW: When looking at the Geekbench scores for Mediatek X20 the device showing the highest ‘multi-core’ score shows also the lowest CPU clockspeed (+5100 points at 1391 MHz). But as we already know Geekbench just shows random numbers here relying on cpufreq info and being blind for the real values. Maybe that’s… Read more »

cnxsoft :
I think most devices support HMP.

Obviously the ones we’re talking here about (RK3399 and both Mediatek MT8693 and MT6797) don’t do it. If Geekbench multi-core score is ~190% or below the single-core score then it runs on 2 CPU cores. RK3399 is a dual-core SoC in multi-threaded performance mode unless you can force the kernel to switch to the ‘slower’ 4xA53 cluster which would show higher multi-core scores.

cnxsoft : TV boxes based on Amlogic S912 can use all 8 cores simultaneously based on info returned by Kodi. The problem is as follows (quoting the link above): ‘Some ARM big.LITTLE CPUs can have cores with different cache line sizes, and pretty much no code out there is ready to deal with it as they assume all cores to be symmetrical.’ SoCs that contain two clusters made of identical cores (S912, Allwinner A83T, Samsung/Nexell S5P6818 and many others — all not implementing big.LITTLE) support HMP perfectly, on those that mix different CPU cores the cache line size matters (or… Read more »

@Jean-Luc Aufranc (CNXSoft) Well, I’ve no idea what’s going on there but what I know for sure is that instead of playing games (Doom 3, Geekbench or the like) it helps more trying to understand what’s happening. Any of the owners of such a device could start to explore how the OS/kernel behaves instead of just producing numbers without meaning. Monitoring the following (in a 1 second loop) seems mandatory to me while increasing the load with single and multi-threaded tasks one after another: grep -c '^processor' /proc/cpuinfo cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq cat /sys/class/thermal/thermal_zone*/temp 123 grep -c '^processor' /proc/cpuinfocat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freqcat /sys/class/thermal/thermal_zone*/temp (count… Read more »

So according to Geekbench, the A64 chip is usually running with at least one dead core?
And without HMP, the processor will not perform as well as we think, in this case, the RK3399?
Also when you said that the A80 is worse than the RK3288 because of software support, isn’t that because of the companies that manufacture the tablet?
So do we trust geekbench, or is geekbench telling the truth because the processor isn’t using HMP?
And one last question, Why did Allwinner cancel the A80 and continue with the A83T, even tho the A83T is worse?

@Ahmed You find in Geekbench browser results for A64 devices running at 4, 3 and only 1 core (easy: simply look at single-core score and compare with multi-core score, if they’re the same it’s only one active core, if it’s ~350% all 4 cores are active — you might get the idea how to calculate ‘active CPU cores’ based on those 2 performance numbers). This conclusion is backed by developing better throttling settings for these SoCs (not only A64 is affected by this ‘kill CPU cores instead of throttling’ but all more recent Allwinner SoCs: H3, A83T, A33…).

As of cache line mismatch: it pretty sucks that user code is trying to mess around with cache “flushing”. Worse – when it does it so lame (as in the example with Mono). This is a task for an OS. The latter should expose an appropriate API and user mode software should make use of it, consistent way, becoming HMP-aware. It should not be any harder than when transiting from a single thread to multithread design. Anyway, it’s just a quirk when some user mode program tries to do an OS job. Even JIT should just do this: compiling its… Read more »

So according to what you’re saying, Geekbench will be telling the correct score of the CPU if there are dead cores, but if the CPU does not use HMP, then Geekbench will be telling us false results because, in real time performance, the CPU is much more powerful than what it says. Right?
If you are right does that mean the RK3399 can get close to the performance of Snapdragon 652 and Exynos octa-core CPUs
