RK3568 adds a third independent display output, a second Gigabit Ethernet port, and PCIe 3.0 with two lanes. RK3566 stops at two displays, one Ethernet port, and PCIe 2.1 with one lane. CPU, GPU, and video decode are nearly identical. If your project needs any of those three RK3568-exclusive features, step up. If it doesn't, save 20-30% on the board and buy RK3566.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  Die <strong>RK3566 vs RK3568<\/strong> comparison is the most practical decision in the Rockchip product family. Both chips are quad-core Cortex-A55 SoCs on 22nm. They share the same Mali-G52 GPU and the same 4K video pipeline. The NPU is nearly identical too. What changes is a small set of I\/O pins. But those I\/O differences can be the deciding factor for your product.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1.5rem;\">\r\n  This guide maps each hardware difference to a real use case.

Their product needed a 15.6-inch customer-facing touch display and a small 7-inch operator confirmation display. Two screens. We reviewed the ieeker RK3566 board with them. It supports two independent outputs. At first glance, it looked like an easy match.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  The issue surfaced during interface mapping. Their carrier board design called for the customer display on HDMI and the operator display on LVDS. That's two outputs \u2014 within RK3566's capability. But they also needed a barcode scanner interface on USB 3.0, a printer on USB 2.0, a receipt cutter on RS232, and a cash drawer trigger via GPIO. When we mapped all of those against RK3566's interface set, everything fit.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  Then their technical lead added one more requirement: they needed an ethernet port for the in-store payment network and a second ethernet port for a cellular failover router for cloud reporting. That's two independent ethernet connections. RK3566 has one.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  We recommended switching to our <a href=\"\/de\/products\/rk3568-core-board-baseboard-development-kit\/\">RK3568 Entwicklungsplatine<\/a>. The dual-MAC ethernet coverage was required. The per-unit cost difference was $11. At their forecast of 1,500 units in year one, that's $16,500 more \u2014 real money, but unavoidable given the network architecture. They approved the switch without pushback because the reason was concrete and the alternative was a USB ethernet dongle they didn't want in a production retail terminal.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  The lesson is consistent: the <strong>RK3566 vs RK3568<\/strong> decision doesn't get made at the start of a project on gut feel about \"needing the better chip.\" It gets made during interface mapping, when real peripheral counts meet real I\/O availability. Do that mapping early. It prevents surprises after PCB layout.\r\n<\/p>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6fdf247 elementor-widget elementor-widget-html\" data-id=\"6fdf247\" data-element_type=\"widget\" data-widget_type=\"html.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\r\n<h2 style=\"font-size:1.5rem;font-weight:700;color:#1a1a2e;margin-top:2.5rem;margin-bottom:1rem;\">\r\n  What's Actually Identical Between RK3566 and RK3568\r\n<\/h2>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  Most comparison articles focus on the differences. It's equally useful to know what you're not giving up when you choose RK3566.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  <strong>CPU performance.<\/strong> PassMark benchmarks show RK3566 within 5% of RK3568 in multi-thread workloads when both run at comparable clock speeds. In real applications \u2014 UI rendering, protocol handling, MQTT publishing \u2014 the difference is imperceptible. You will not feel it.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  <strong>GPU performance.<\/strong> Both use the Mali-G52 2EE. Both support OpenGL ES 3.2, Vulkan 1.1, and OpenCL 2.0. Qt Quick applications run identically. Android UI performance is the same. Frame rates on equivalent workloads are equal.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  <strong>4K video decode.<\/strong> Both chips decode H.265, H.264, and VP9 at 4K@60fps using the same VPU. Playing 4K content on a signage display is identical on either chip.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  <strong>NPU and AI inference.<\/strong> Both use the RKNN architecture and the same RKNN-Toolkit2 toolchain. A model quantized and validated on RK3566 deploys directly to RK3568 without reconversion. They're not identical in raw TOPS figures across all documentation, but for the workloads they're both suited to \u2014 face detection, classification, anomaly scoring \u2014 performance is equivalent in practice.\r\n<\/p>\r\n \r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  <strong>OS ecosystem.<\/strong> Both support Android 11\/12, Debian, Ubuntu, and Buildroot.

A carrier board designed for RK3566 cannot be populated with RK3568. Choosing between them is a schematic-level decision. Make it before PCB layout.\r\n<\/p>\r\n \r\n<h3 style=\"font-size:1.1rem;font-weight:600;color:#1a1a2e;margin-top:1.25rem;margin-bottom:0.5rem;\">\r\n  Which chip is better for a Modbus IoT gateway?\r\n<\/h3>\r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  It depends on your network architecture. If you only need one Ethernet connection, RK3566 is fine and cheaper. If you need separate field-device LAN and cloud WAN interfaces, RK3568's dual GbE is required. Modbus RTU polling over RS485 UART works identically on both chips.\r\n<\/p>\r\n \r\n<h3 style=\"font-size:1.1rem;font-weight:600;color:#1a1a2e;margin-top:1.25rem;margin-bottom:0.5rem;\">\r\n  Does RK3566 have SATA support?\r\n<\/h3>\r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  No. SATA III is exclusive to RK3568 in this family. RK3566 can use eMMC and microSD for local storage, and supports one PCIe 2.1 lane for an M.2 NVMe drive if needed. For applications requiring 2.5-inch SSD storage \u2014 NVR systems, large local historians \u2014 RK3568 is the correct choice.\r\n<\/p>\r\n \r\n<h3 style=\"font-size:1.1rem;font-weight:600;color:#1a1a2e;margin-top:1.25rem;margin-bottom:0.5rem;\">\r\n  Is there an industrial-grade version of RK3566?\r\n<\/h3>\r\n<p style=\"font-size:1rem;line-height:1.8;color:#374151;margin-bottom:1rem;\">\r\n  Yes. As with RK3568J, there is an RK3566 industrial-grade variant validated for extended temperature operation. Ask your board vendor specifically for the J-grade SoC if your deployment environment runs above 50\u00b0C ambient or below 0\u00b0C. Consumer-grade RK3566 is rated 0\u00b0C to 70\u00b0C junction temperature.\r\n<\/p>\r\n \r\n<!-- References -->\r\n<div style=\"margin-top:2.5rem;padding-top:1.5rem;border-top:1px solid #e2e8f0;\">\r\n  <p style=\"font-size:0.9rem;font-weight:700;color:#374151;margin-bottom:0.75rem;\">Quellen und Referenzen<\/p>\r\n  <ol style=\"font-size:0.87rem;line-height:1.9;color:#6b7280;padding-left:1.25rem;\">\r\n    <li><a href=\"https:\/\/www.cnx-software.com\/2020\/12\/16\/rockchip-rk3566-and-rk3568-datasheets-and-features-comparison\/\" target=\"_blank\" rel=\"noopener noreferrer\">Rockchip RK3566 and RK3568 Datasheets and Features Comparison \u2014 CNX Software<\/a><\/li>\r\n    <li><a href=\"https:\/\/rockchips.net\/rk3566-vs-rk3568\/\" target=\"_blank\" rel=\"noopener noreferrer\">RK3566 vs RK3568: Practical Comparison \u2014 Rockchips.net<\/a><\/li>\r\n    <li><a href=\"https:\/\/www.cpubenchmark.net\/compare\/5429vs5305\/Rockchip-RK3566-vs-Rockchip-RK3568-EVB2-LP4X-V10-Board\" target=\"_blank\" rel=\"noopener noreferrer\">Rockchip RK3566 vs RK3568 Benchmark Comparison \u2014 PassMark CPU Benchmark<\/a><\/li>\r\n    <li><a href=\"https:\/\/en.wikipedia.org\/wiki\/CAN_bus\" target=\"_blank\" rel=\"noopener noreferrer\">CAN Bus Protocol \u2014 Wikipedia<\/a><\/li>\r\n  <\/ol>\r\n<\/div>\r\n \r\n<\/div><!-- end .iek-wrap -->\r\n<\/body>\r\n<\/html>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Short answer: The RK3566 vs RK3568 decision comes down to three hardware gaps.
