Cool Pi 4 Model B – A much faster alternative to Raspberry Pi 4 SBC

Cool Pi 4 Model B is a powerful alternative to Raspberry Pi 4 SBC with mostly the same form factor and interfaces but equipped with a Rockchip RK3588S octa-core Cortex-A76/A55 processor that will run circles around the Broadcom BCM2711 SoC found in the Raspberry Pi board.

We’ve already reviewed Rockchip RK3588/RK3588S single board computers and mini PC such as Rock 5B, Khadas Edge2 Pro, and Mekotronics R58, and we were impressed by the performance, but if you prefer to have such a board in Raspberry Pi 4 form factor, then the Cool Pi 4 Model B might be for you.

Cool Pi 4 Model B

Cool Pi 4 Model B specifications:

  • SoC – Rockchip RK3588S octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores, an Arm Mali-G610 GPU with OpenGL ES 3.2,  OpenCL 2.2, and Vulkan 1.1 support, 8Kp60 video decoder for H.265/AVS2/VP9/H.264/AV1 codecs, 8Kp30 video encoder, and a 6 TOPS NPU
  • System Memory – 4GB, 8GB, or 16GB LPDDR4
  • Storage – 32GB, 64GB, or 128GB eMMC flash module, MicroSD card socket
  • Video Output
    • Micro HDMI 2.1 port up to 8Kp60
    • miniDP 1.4 up to 4Kp60
    • MIPI DSI connector
  • Camera I/F – MIPI CSI connector
  • Audio – 3.5mm earphone jack
  • Networking
    • Gigabit Ethernet RJ45 with optional PoE support
    • Dual-band WiFi 6 and Bluetooth 5.0 module (AIC8800) with ceramic antenna
  • USB – 2x US 3.0 Type-A ports, 2x USB 2.0 Type-A ports
  • Expansion – 40-pin Raspberry Pi compatible GPIO header with GPIO, I2C, SPI, UART, CAN bus, etc…
  • Power Supply – USB Type-C port
  • Dimensions – 85 x 56mm (close to Raspberry Pi 4 form factor)

Raspberry Pi 4 Rockchip RK3588S

Cool Pi 4 eMMC flash MicroSD cardNote the specifications above are for version V11, and there was a V10 with AP6256 wireless module no onboard antenna, and a different eMMC flash module connector (GB042 vs BM20B). Cool Pi provides Debian 11 Desktop and Ubuntu 22.04 Desktop images for either microSD card or eMMC flash storage. The board is supposed to support Android 12 too, but I did not find the image in the forums (Note: the website is really slow and requires email registration to even just browse the forums). The source code for the U-boot bootloader and the Linux kernel can be found on Gitee.

As far as I can tell, the Cool Pi 4 supports all hardware features of the Raspberry Pi 4, but replaces one of the micro HDMI ports by a mini DisplayPort connector. Extra features include support for eMMC flash modules, 8K video playback and output, WiFi 6, and a built-in 6 TOPS AI accelerator. Performance-wise, the Rockchip RK3588S will be in a class of its own, as we’ve found it to be three times faster with 7-zip and four times faster for web browsing (Speedometer) in Linux when compared to Raspberry Pi 4, as well as having a GPU that delivers four times the 3D graphics performance of the Amlogic S922 SoC found in the ODROID-N2+ SBC. The GPU is also 12 times faster than the Raspberry Pi 4 using 3DMark results but I’m not sure how optimized Android is for the Pi board.

The main question will be software support as we still had some issues during reviews, but whether this impacts you or not will depend on your use case and/or skills set. Pricing will also play a major role since the price of the Cool Pi 4 Model B is quite higher, currently starting at $142 including shipping on Aliexpress for the model with 4GB RAM, and no eMMC flash module. The company is also working on the Cool Pi 5 system-on-module based on Rockchip RK3588S, but no details are available just yet.

Their website is limited to 1 Mbps (likely behind an ADSL line), and takes approx 1 minute to load due to large images (about 6 MB of contents for the page). Since there’s nothing to see there except links to a registration page, I guess there’s no point clicking and rendering it unresponsive for those who have an account… But they should at least recompress their images; the photos used divide their size by 8 once saved to JPG without losing quality, this would significantly improve the situation for them. One must also wonder if it’s worth engaging with a… Read more »

This is typical of something hosted behind the great firewall. I see they are hosting via HTTPS – I have seen a gigabit connection turn to a few kb/s when using HTTPS through Chinese border routers.

142$ with no eMMC ? orange pi has similar specs for less than half !
maybe there is something im missing

I was thinking the same thing. It does seem a bit pricey. The hardware and the specs are a bit attractive. Perhaps they’re thinking they can get a bit more $$ based on from factor and the current shortages. They’ll certainly be filling a gap that’s for sure. Let’s hope for their sake that the software is on point.

That’s cheaper than a Rock 5 model B 8GB from Okdo in Europe

Likely with a very different level of support as well… At some point you get what you pay for.

You are right, but you don’t get some of the features that comes with the Rock 5B and the full capability of the RK3588, like 2,5Gbit Ethernet, HDMI input etc. There was a post a while ago outlining the deltas between the SoCs: https://www.cnx-software.com/2022/01/12/rockchip-rk3588s-cost-optimized-cortex-a76-a55-processor/ (BTW, I’m Nils from OKdo, happy to see the interest in these boards.)

Hmm I didn’t know Gitee. Yet another github imitation. However it also requires to log in everywhere you click. This company seems to be having a serious problem with leaving their information accessible to the public, that’s really concerning, and should be sufficient to scare any customer away.

OK but then it’s really odd to think that in order to *read* git logs you have to authenticate via google or github, which for them basically means giving all their browsing habits and history to a rival. Anyway, with such practices they’re unlikely to sell anything outside of their country.

I suspect the problem for Rockvhip is if they make the RK3588S to cheap it will reduce the market for the RK3366, RK3568 and RK3399 SoC. Even at $99 – $150 the RK3588S devices already bump against multi function RK3568, RK3566 boards. But the RK3588S is so much faster.

Why don’t they just stop making the decade old designs?

Its like saying the problem for amd zen4 chips, is if they make them at a price to compete with Intel, it will eat into the sales of Zen 1 chips.

Willy

I think it’s a bit too early but at least they should proceed like others, which is to reduce the price of the older leading products (that’s probably the case though). RK3399 is indeed a bit old but fairly well supported in mainline nowadays, so it does have its value for certain products. 3566/3568 are quite young, excellent performers in a wide range of applications as their cores are correct, power drain is low, I/Os are rich, and there’s no reason to affect their price. 3588 is just the high-end, i.e. 3568 for those who want maximum power. The 3588S… Read more »

That is a 12W TDP device. Not sure you can use it to its full potential with regular Pi shields.

That AIC8800(M) module looks very interesting, but with no western availability, apparently.

Rasbperry Pi 4 was release more than 3 years ago.
If a new SBC trying to compete with that, it should compete with:

  1. Performance – expected to be much better after 3 years
  2. Power consumption
  3. Price, RPI was sold for 35$ for the base version
  4. Software support
  5. Build/parts quality (RPIs last for years, working 24/7)

None of the new boards gives a fight to RPI, I even prefer RPI 2 over all of the new power hungry boards with multiple video outputs / lan ports.

Willy

well, you forgot:

  • availability: rpi4 impossible to find these days for less than $130 or so for the 2GB version.

I think that’s in part why SBC vendors are rushing on the 3588(S): way faster than RPi in the same price range.

I’d like to see something like this board with an m.2 slot for an SSD and options for 4/8GB that costs around $100; Say $80 for the 4GB version and $100 for the 8GB version.

And for god’s sake, skip the emmc. The board can be a little bigger as well.

Is that too hard to ask?

I see it only has 1Gbit Ethernet while the ROCK 5B has 2.5Gbit data rates, wonder why it was implemented differently. No signs of FCC and CE logos on the board and the PMU chip is so far away from the USB power socket, perhaps they have radiated emission problems with a design like that and such long high power tracks. Why go for a credit card form factor similar to incumbent boards but it clearly won’t fit in an enclosure (power button and different port locations)? Stereo out is nice, any mention of microphone-in like other recent boards have… Read more »

Raspberry Pi USED to be the single board pc to get. But they sold out. They deliberately created a huge production shortage which allowed outrageous profiteering — the the corporation embraced the inflated prices to rack up HUGE profit margins. BOYCOTT ALL THINGS RASPBERRY!

List price is meaningless these days. What I’d love is ongoing reporting of comparative features of devices available this week with price to my doorstep.

Many of the devices reported here are vapor. These days, unfortunately, Raspberry Pi, whom I’d much rather support, are vapor too!

It would seem that the non-official PoE hat that I have here does work. It has the 4-pin PoE header in the same position and uses a Raspberry Pi-compatible GPIO layout so all looks good there.

You should start with software and hardware compatibility. Cool hardware with crap software is not fun. If add-on boards for a Raspberry Pi do not work, then say so up front. I do not want to wade through the specs, only to discover actual use is a PITA. We went through the lesson back in the 1980s with (not so) PC-compatible computers. A common delusion of hardware folk is that if they make “kewl” hardware, then the software will somehow just appear. Does not work that way, then or now. I would be delighted with a compatible alternative to the… Read more »

I was very excited reading all the specs at first but I’m looking for something that would be able to handle and output 4K 120-160hz + HDR to use Kodi on and display on my brand new Samsung S95 65 tv which has 4k HDR10 and over 120hz. Any suggestion unless there is a way to get this out of this one ?

Not sure anyone is going to necessarily cross shop this with a Pi 4. Although given the ongoing shortages and the price gouging currently it’s not an unrealistic scenario to find oneself in.

Either way a worthy inclusion, at not unreasonable price point. I don’t know that it would be my first choice but having options is never a bad thing.

NooB question: can you run Raspbian on Rockchip CPUs? They’re both ARM 64-bit. I’m looking for something for my kids that is powerful enough for desktop use but has great educational features. The Raspbian OS is great for education and I would love to be able to run it on a Rockchip board. I also wonder if the “R’Pi4” form factor also means that the connectors line-up to the R’pi as well. There are some cool kits for putting the R’Pi4 into a commodore 64 style keyboard, or into a laptop. Would love if this board could fit easily in… Read more »
