Why are the chips should be upgraded?
Let’s compare it to the S905X2 and see how it differs after it is upgraded.
In comparison to the S905X2, S905X3 is the Cortex-A55 cores can deliver more performance than compared to Cortex-A53 in memory, benchmarks, around 20 to 30% performance improvement for tasks at the same frequency. Amlogic S905X3 also has some optional features like the Neural Network Accelerator and a Cortex-M4 core for always-on processing. S905X3 is an advanced application processor designed for hybrid OTT/IP Set Top Box (STB) and high-end media box applications. It integrates a powerful CPU/GPU subsystem, the main system CPU is a quad-core ARM Cortex-A55 CPU with unified L3 cache to improve system performance. In addition, the Cortex-A55 Cores includes the NEON SIMD co-processor to improve software media processing capability. The graphics subsystem consists of two graphics engines and a flexible video/graphics output pipeline. The ARM G31 MP2 GPU handles all OpenGL ES 3.2 Vulkan 1.0 and OpenCL 2.0 graphics programs, while the 2.5D graphics processor handles additional scaling, alpha, rotation, and color space conversion operations. Together, the CPU and GPU handle all operating systems, networking, user-interface and gaming related tasks.
The video output pipeline includes Dolby Vision optional, HDR10+, HDR10, HLG and PRIME HDR processing, BT.709/BT.2020/BT.2100 processing, motion adaptive edge enhancing de-interlacing, flexible programmable scalar, and many picture enhancements filters before passing the enhanced image to the video output ports. Amlogic Video Engine (AVE-10) off-loads the Cortex-A55 Cores from all video CODEC processing. It includes dedicated hardware video decoder and encoder. AVE-10 is capable of decoding 4Kx2K resolution video at 60fps with complete Trusted Video Path (TVP) for secure applications and supports full formats including MVC, MPEG-1/2/4, VC-1/WMV, AVS, AVS+, AVS2 RealVideo, MJPEG streams, H.264, H265-10, VP9 and also JPEG pictures with no size limitation. The independent encoder is able to encode in JPEG or H.265/H.264 up to 1080p at 60fps.
This new VPU also support 3D, Dynamic HDR (w/EMP), CEC and HDCP2.2, ALLM (Auto Low Latency Mode) support, stereo audio DAC, a CVBS output, multiple TDM, PCM, I2S and SPDIF digital audio input/output interfaces, and 8 channel far-field PDM digital microphone (DMIC) inputs.
It also has built-in Voice Activity Detection (VAD) module for ultra-low power operations during system standby. S905X3 also integrates a set of functional blocks for digital TV broadcasting streams. The built-in two demuxers can process the TV streams from the serial and parallel transport stream input interface, which can connect to an external tuner/ demodulator. The processor has the rich advanced network and peripheral interfaces, including a 10/100/1000M Ethernet MAC with RGMII, 10/100M Ethernet PHY, a set of multi-PHY for USB2, USB3 and PCIe, and multiple SDIO/SD card controllers, UART, I2C, high-speed SP I and PWMs.
The standard development environment utilizing GNU/GCC Android toolchain is supported. Next, we compare several actual data tests to see the actual difference between S905X3 and S905X2.
After testing the data, it can be clearly seen that the performance of all aspects of S905X3 is higher than that of S905X2. Beelink will introduce the GT1 mini② to replace the GT1 mini sales, so stay tuned.
