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.Founders Edition specifications verified by MSI's retained technical page and datasheet; stock PNY Blower specifications verify memory bandwidth.

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.1480 MHz base and 1582 MHz boost (MSI Founders Edition specification)

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 Sapphire's original 4 GB power is only stated as less than 225 W, so its numeric power remains unpublished.11 Gbps GDDR5X (PNY stock Blower); MSI lists 11010 MHz memory speed

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; up to 4 displays; HDCP 2.2. MSI's datasheet connection illustration names DVI-D despite its output specification omitting it; the Founders Edition has no native DVI connector.
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
Power connectorOne 8-pin on the pictured MSI ARMOR, original Sapphire Pulse and both named 2048SP boards1 × PCIe 6-pin and 1 × PCIe 8-pin
Recommended power supplyAMD and MSI specify 500 W for the original model; Sapphire specifies 500 W for original Pulse and 450 W for the named 2048SP boards600 W
Slot widthOriginal Sapphire Pulse and named 2048SP designs occupy two slots; pictured MSI ARMOR is 38 mm thick2-slot (Founders Edition)
Size (reference card)Pictured MSI ARMOR is 269 × 125 × 38 mm and 653 g. Original Sapphire Pulse is 230 × 125 × 40 mm; named 2048SP 4 GB is 241 × 120 × 42 mm and 8 GB V2 is 212 × 111 × 40 mm.266 × 111 × 40 mm (MSI Founders Edition)
Video encode and decodeAMD publishes H.264 and H.265/HEVC encoding and decoding; Sapphire specifies PCIe 3.0 for the named variants–
