Amlogic S922X is an upcoming hexa-core processor with four Cortex A73 cores and Cortex-A53 cores mostly designed for devices running Android TV P, but it could also become potentially interesting for development boards and other products like Arm laptops.
There aren’t any products available for purchase, but some results appeared on Geekbench in recently showing Droidlogic galilei board with a 6-core processor from Amlogic which has to be Amlogic S922X processor. There’s also g12b_w400 with a 6-core processor from Amlogic, but that’s A311D.
So Amlogic S922X benchmarks report 1212 points for the single-core score, and “only” 3,133 points for the multi-core score. The base frequency in “Droidlogic galilei” board is 1.80 GHz, but 1.90 GHz in g12b_w400 “A311D” platforms. Strangely enough, the single core score is only 9xx in the latter. It’s very likely the maximum frequency drops when all four Cortex A73 cores are under loads, as the multi-core score does not scale.
Let’s compare those score to Amlogic S905X (Libre Computer AML-S905X-CC SBC), and there are significant improvements as expected.
Comparing Amlogic S922X to Rockchip RK3399 is somewhat disappointing. The single-core score is the same, and that one should be expected since Cortex-A72 and Cortex-A73 are supposed to have the same performance, with the latter having better thermals, but the multi-core score is only slightly better despite S922X having four “fast” cores against two “fast” cores for RK3399.
Having said that I’d expect the scores for Amlogic S922X to somewhat improve since:
- 32-bit Android was used with S922X against 64-bit Android for RK3399
- Hardware accelerated AES for S922X is not ready yet, or there are some problems with the implementation as shown in the screenshot below.
Nevertheless, the early results look good so far, and Amlogic S922X should be a promising platform competing against Rockchip RK3399 processor, and offering a significant upgrade compared to previous Amlogic processors. The CPU is only one part of modern SoC, so we’ll have to see how to GPU, and high-speed interfaces perform in the new SoC.
