At CES 2018, Rockchip showcased the RK3328 TV box solution, aimed at the mid-to-high-end market. Let’s delve into its performance through this in-depth review.
1. RK3328 Hardware Parameters Score 18000+
CPU: Equipped with a 64-bit A53 architecture quad-core processor, clocked at 1.5GHz.
GPU: Features a Mali-450MP2 graphics processor.
System: Supports Android 8.1 and Linux OS.
Data Transmission: Supports USB 3.0 and Gigabit Ethernet data transmission.
Picture Quality: Supports the latest 4K Ultra HD (UHD Premium), HDR10/HLG, and other international standards.
(Latest 4K Ultra HD standards: 3840×2160 or 4096×2160 resolution, supports HDR high dynamic range rendering technology, supports H.265 hardware decoding, achieving 10-bit color depth).
The RK3328 solution supports GOOGLE-recognized DRM Widevine Level 1 certification and Microsoft PlayReady certification, and has been certified by the China Smart Home Industry Alliance (China Telecom, China Unicom, China Mobile).
2. Picture Quality Test: True 4K + HDR Display Effect Excellent, HDR2SDR Technology Enhances Picture Quality
The RK3328 solution supports the latest 4K Ultra HD (UHD Premium), HDR10/HLG, and other international standards. By playing 4K test images, it can be observed that the font size and color meet the 4K resolution standards, and all color blocks in the image can be clearly distinguished, even the densely packed color block structures at the bottom can display details correctly, achieving 4K resolution.
In the 4K high bitrate (125Mbps) video test, even in complex scene scenarios, the RK3328 box still performs well, clearly showcasing details in street vehicles, streetlights, rooftops, and distant scenery.
Additionally, the RK3328 supports HDR high dynamic range rendering technology, significantly increasing the contrast of displayed images, allowing both bright and dark details to be fully exhibited. Let’s take a look at the specific test comparisons below.
With HDR technology, the detail contrast of bright and dark areas is greatly improved, enhancing the contrast and saturation of skin tones and clothing colors. Compared to without HDR, the overall image display is brighter, and the color depth is higher.
In the scene images, HDR technology not only improves brightness contrast but also enhances the overall display effect.
From actual testing, Rockchip RK3328’s HDR to SDR conversion technology provides an enhanced picture quality experience even on regular TVs.
3. Data Transmission Test: RK3328 Supports USB 3.0, Speed Boosted by 3x
The RK3328 supports USB 3.0 and Gigabit network interfaces, ensuring stable and fast data transmission.
To test the data transmission speed of the USB 3.0 interface, we measured writing and reading a certain amount of data, performing each read and write three times and taking the average. Finally, we selected 16MB, 8MB, 4MB, 2MB, and 1MB for data recording. Using 16MB as the reference standard, the average write speed was 95.39MB/s, and the average read speed was 97.67MB/s.
In the USB 2.0 interface data speed test, we observed that the average write speed for 16MB was 34.64MB/s and the average read speed was 33.07MB/s.
The curve comparison graph visually reflects that USB 3.0 is nearly 3 times faster than USB 2.0 in both writing and reading speeds, resulting in faster data transmission.
Furthermore, we also compared the time taken to copy a 1.1G test video using the ES File Explorer. The RK3328 box completed the transfer in 29 seconds, achieving a transfer speed about 3 times that of typical TV boxes.
4. Supports Various Video Decoding: 4K, Different Formats, and Bitrates
The local source decoding capability has always been a focal point for film enthusiasts. Through numerous video comparison tests of 4K, different formats (including m2ts, tp, flv, evo, and other “rare” video formats), and different bitrates, the RK3328 box can smoothly play all tested videos.
As a mid-to-high-end TV box processor chip, the Rockchip RK3328 demonstrates excellent performance in boot speed, data transmission, picture display, and video decoding tests.
