ArchitectureFourth-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 original 8 GB reference baseline uses fourth-generation GCN (Polaris), 36 compute units, 32 ROPs and 144 texture units. Photo shows MSI's factory-overclocked ARMOR 8G OC, not a reference card. Later 2048SP configurations below identify specific Chinese-market Sapphire boards.

Base clockAMD 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.Original AMD baseline is 1,257 MHz base and 1,340 MHz boost. Pictured MSI ARMOR 8G OC boosts to 1,366 MHz. Sapphire's 2048SP pages state core frequencies of 1,306 MHz (4 GB) and 1,284 MHz (8 GB V2) without a boost label, so numeric boost is omitted for those configurations.

Memory detailMSI ARMOR 4G and 8G both specify 7,000 MHz effective GDDR5. AMD publishes up to 224 GB/s for the GPU, but MSI does not state bandwidth separately for either capacity; the 8 GB configuration therefore omits it.Original stock Sapphire Pulse 8 GB SKU 11265-06 has 8,000 MHz effective memory; original stock 4 GB SKU 11265-10 and the named 2048SP boards have 7,000 MHz. AMD publishes 256 GB/s only for the 8 GB baseline; bandwidth is omitted for the others. Sapphire's original 4 GB power is only stated as less than 225 W, so its numeric power remains unpublished.

Interface–PCIe 3.0
Display outputs3 × 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 ARMOR has 2 × DisplayPort, 2 × HDMI and dual-link DVI-D. Sapphire 2048SP 4 GB SKU 11265-65-18 has DVI-D only; 8 GB Pulse V2 SKU 11265-70-48 has one HDMI 2.0b, one DisplayPort 1.4 and DVI-D. AMD's reference feature table lists DVI as No; partner outputs vary.
Maximum resolution–MSI ARMOR specifies 7680 × 4320 and five displays; Sapphire's named 2048SP 4 GB board is limited to 1920 × 1200 at 60 Hz over DVI-D. Its 8 GB V2 board lists DisplayPort 5120 × 2880 at 60 Hz and HDMI 4096 × 2160 at 60 Hz.
