Boost clock
Boost clock	1,244 MHz	2,491 MHz (better)
Architecture
Architecture	Fourth-generation GCN (Polaris), 128 texture units, 32 ROPs and 5.7 billion transistors. AMD's retained support page is labelled RX 570 (OEM) and includes slower OEM clocks; the original retail baseline and both named MSI ARMOR configurations use the published maximum 1,244 MHz. Photo shows MSI ARMOR 4G, not an AMD reference board.	AMD GPU specification baseline with 28 compute units, 64 ROPs and 112 texture units. Photo shows MSI's stock-clock MECH 2X 8G partner card.

Base clock
Base clock	AMD publishes a 926–1,168 MHz OEM range; the original retail baseline is 1,168 MHz (PCWorld). Both named MSI ARMOR boards publish up to 1,244 MHz core frequency without a separate base figure.	AMD publishes a 2,044 MHz game clock; the 2,491 MHz boost is the maximum frequency for burst workloads

Board power	150 W	132 W (better)
Interface
Interface	–	PCIe 4.0
Display outputs
Display outputs	3 × DisplayPort, 1 × HDMI and dual-link DVI-D on both MSI ARMOR boards. AMD lists DisplayPort 1.4 HDR and HDMI 4K60 support, but DVI as No; partner outputs differ.	Pictured MSI MECH 2X has 3 × DisplayPort 1.4 and 1 × HDMI 2.1; AMD specifies DisplayPort 1.4a and HDMI 2.1 with variable refresh rate and FRL
Maximum resolution
Maximum resolution	–	7680 × 4320 and up to four displays on MSI's specification
Power connector
Power connector	One 8-pin on both MSI ARMOR boards	1 × 8-pin
Recommended power supply
Recommended power supply	450 W	AMD specifies 450 W; MSI recommends 500 W for its pictured MECH 2X. Requirements depend on the rest of the system.
