Renesas RZ/G2L MPUs Feature Cortex-A55 & Cortex-M33 Cores for AI Applications

Block Diagram of RZ-G2L

Renesas Electronics Corporation announced RZ/G2L MPUs, allowing enhanced processing for an extensive variety of AI applications. The RZ/G2L group of 64-bit MPUs includes three new MPU models featuring Arm Cortex-A55, and an optional Cortex-M33 core. These are RZ/G2L, RZ/G2LC, and RZ/G2UL MPUs. The Cortex-A55 CPU core typically delivers approximately 20 percent improved processing performance compared with the previous Cortex-A53 core, and according to Renesas, is around six times faster in “essential processing for AI applications”. The company already has four mid to high-end design level MPUs including RZ/G2E, RZ/G2N, RZ/G2M, and RZ/G2H, with combinations of Cortex-A53 and Cortex-A57 cores. The new RZ/G2L group of three MPUs forms the entry-level design with Cortex-A55. Hence, the seven MPU models together provide scalability from entry-level to high-end design. Common Key Features in RZ/G2L, RZ/G2LC, and RZ/G2UL MPUs Up to 2x Cortex-A55 cores Cortex-M33 core Camera interface (MIPI-CSI) Display interface (Parallel-IF) USB2.0 interface 2ch, SD interface 2ch CAN interface (CAN-FD) 2x Gigabit Ethernet DDR4 […]

Amlogic S905X3 vs S905X4 – Features Comparisons

Amlogic S905X3 vs S905X4

AV1 capable Amlogic S905X4 processor has been expected for more than a year, and only now are we starting to see announcements of S905X4 TV boxes and development kits. So it may be a good time to compare the features of the new Amlogic S905X4 processor again its predecessor, namely S905X3, and see if there are other notable differences apart from support for AV1 open video codec. We’ll use data from S905X3 specifications,  S905X2 vs S905X3 comparison, and a post on SDMC LinkedIn page. Amlogic S905X4 will be slightly faster due to the higher (default) maximum CPU frequency of 2.0 GHz, but most people will not notice the difference.  S905X4 is supposed to support Vulkan 1.1, while S905X3 does not, but I believe this is just due to more up-to-date Android SDK, and not differences in the silicon itself. S905X4 supports Nagra DRM, a more recent version of HDCP, and integrates a dual-core audio DSP which may be why there’s […]

Rockchip RK3566 and RK3568 datasheets and features comparison

RK3566 vs RK3568

We first covered Rockchip RK3566 processor in February, but we’ve been informed the specifications have changed since then, and earlier this month, we also wrote about RK3568 quad-core Cortex-A55 processor with the same base features but some extra I/Os. But due to NDAs, people familiar with the chips could not release too many details, so we did not get the full picture. This has just changed as the datasheets for both processors have just dropped from somewhere here and there, and we can get a much closer look. I’ve highlighted the obvious differences above, with the big ones being the PCIe interface and RK3568 having dual Gigabit Ethernet. The other features comparison can be found in the table below. Important note. Rockchip RK3566 and RK3568 are using Multi-PHY Interfaces, and while the table above lists all possible interfaces, they can not all be used at the same time. PCIe, SATA, USB 3.0 are multiplexed in most cases as shown in […]

Rockchip RK3568 processor to power edge computing and NVR applications

Rockchip RK3568

We recently reported on the Rockchip developer conference (RKDC) 2020, and especially the upcoming Rockchip RK3588 Cortex-A76/A55 processor that packs a lot of power and features, and is now scheduled to launch in Q3 2021. But as you can imagine there were other products revealed during the conference, including the new Rockchip RK3568, similar to the previously announced RK3566, and designed for edge computing and network video recorder (NVR) applications. There’s also an RK353X processor specifically designed for NVR application that should have similar performance as RK3568, but a lower cost, as well as two UP camera SoC with RV1106 and RV1128. CNX Software managed to obtain the presentation for the RK3568 processor from the conference so we’ll focus on the quad-core Cortex-A55 processor in this post. Rockchip RK3568 specifications: CPU – Quad-core Cortex-A55 processor with NEON and FPU GPU – Mali-G52 EE with support for OpenGL ES 1.1 to 3.2, Vulkan 1.1, OpenGL 2.0 AI accelerator – 0.8 TOPS […]

Khadas VIM3L (Amlogic S905D3) Benchmarks, Settings & System Info

Khadas VIM3L Heatsink

Khadas VIM3L is the first Amlogic S905D3 SBC on the market and is sold as a lower-cost alternative to the company’s VIM3 board with a focus on the HTPC / media player market. Shenzhen Wesion was kind enough to send me a sample for review, and I’ll start by checking out benchmarks and system information in Android 9.0 Pie operating system. I also plan to perform a more detailed review with Android 9.0 and CoreELEC with a focus on media playback. I received the bare board only, and the first thing I did was to install it the heatsink I received for VIM3 and in turn, install it in the acrylic case. The company told me the heatsink is not really necessary “for normal purpose using like watch TV”, but it should be installed for performance tests and heavy workloads. I’d still recommend purchasing the heatsink to make sure it works well during the summer months as well. Upgrading Android […]

X96 Air Amlogic S905X3 Android 9.0 TV Box Sells for $30 and Up

X96 Air

Amlogic S905X3 is the first Arm Cortex-A55 processor from the company, and we’ve seen it does not differ that much from the previous generation in our S905X3 vs S905X2 comparison. The Cortex-A55 cores have similar performance compared to Cortex-A53 cores., but S905X3 SoC does provide support for DDR4 memory up to 3200 MHz which may improve 4K HDR video playback and 3D gaming, as well a 1.2 TOPS NPU for AI workloads such as voice recognition. The first Amlogic S905X3 TV box launch we covered was Beelink GT2 Mini with price starting at just under $50 for the 2GB/16GB version and $70 with 4GB and 64GB RAM. Prices have now somewhat come down, but if you’re looking for a cheaper model X96 Air is now offered on Aliexpress for $29.39 including shipping with 2GB RAM, 16GB flash, while the 4GB/32GB variant is sold for $38.01, and up to $40.95 with 64GB storage. You can also spend a bit more if […]

Beelink GT1 Mini 2 Amlogic S905X3 TV Box is Now Sold for $70

Amlogic S905X3 Android TV Box

Around two weeks ago, we covered Beelink GT1 Mini 2 that was one of the first TV boxes to get an Arm Cortex-A55 processor, namely the latest Amlogic S905X3 quad-core processor, and the company also shared benchmarks showing Amlogic S905X3 was only marginally faster than Amlogic S905X2 quad-core Cortex-A53 SoC. As shown in our S905X3 vs S905X2 comparison, the main improvements for the former are the presence of an NPU for AI acceleration, and support for faster DDR4 memory up to 3,200 MHz. Upon the announcement, one person noticed the TV box was sold for $80 on GearBest with the default configuration of 4GB RAM and 64GB storage, and while the price has now dropped to $73.99 on GB, Beelink GT1 Mini 2 can now be purchased found for just $69.99 on Aliexpress including worldwide shipping. Beelink GT1 Mini 2 specifications: SoC – Amlogic S905X3 quad-core Arm Cortex-A55 processor @ 1.9 GHz with Arm Mali-G31MP2 GPU with support for OpenGL […]
