ArchitectureAMD 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.GP104; 7.2 billion transistors; 160 texture units and 64 ROPs. Main specifications and photo describe the original Founders Edition; the later 11 Gbps memory version is represented by MSI's GAMING+ 8G in its default Gaming mode.

Base clockOriginal 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.1607 MHz (original Founders Edition); MSI GAMING+ 8G has 1620 MHz base and 1759 MHz boost in Gaming mode, 1632/1771 MHz in OC mode and 1607/1733 MHz in Silent mode.

Memory detailOriginal 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 Sapphire's original 4 GB power is only stated as less than 225 W, so its numeric power remains unpublished.Original 10 Gbps GDDR5X; MSI GAMING+ 8G lists 11010 MHz effective memory speed. Its bandwidth is not published in the maker's datasheet and is omitted from that configuration.

Display outputsPictured 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.3 × DisplayPort 1.4, 1 × HDMI 2.0b and 1 × dual-link DVI-D; up to 4 displays; HDCP 2.2 (MSI Founders Edition). NVIDIA's launch table calls the DVI connector DVI-I; MSI's actual card specification identifies DVI-D.
Maximum resolutionMSI 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.7680 × 4320 (MSI Founders Edition)
