What reviewers say

Reviewers found capable 1080p performance competing with the GTX 1060, but a modest RX 480 refresh with higher power use. PC Gamer tested ASUS Strix T8G OC; TechRadar and PCWorld tested Sapphire Nitro+. These reviews cover original 2,304-processor 8 GB cards, with board-specific cooling, rather than the 4 GB or later 2048SP versions.

Performance

Chip maker: AMD
Architecture: GCN 4
Shader cores: 2,304 or 2,048
Boost clock: 1,340 MHz or –
Architecture: 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.
Manufacturing process: 14 nm
Ray tracing: No hardware ray accelerators
Base clock: 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

Video memory: 8 GB GDDR5 or 4 GB GDDR5
Memory bus: 256-bit
Memory bandwidth: 256 GB/s or –
Memory detail: 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 Sapphire's original 4 GB power is only stated as less than 225 W, so its numeric power remains unpublished.

Connections and power

Board power: 185 W, – or 150 W
Interface: PCIe 3.0
Display outputs: 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.
Power connector: One 8-pin on the pictured MSI ARMOR, original Sapphire Pulse and both named 2048SP boards
Recommended power supply: AMD and MSI specify 500 W for the original model; Sapphire specifies 500 W for original Pulse and 450 W for the named 2048SP boards
Slot width: Original Sapphire Pulse and named 2048SP designs occupy two slots; pictured MSI ARMOR is 38 mm thick
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.
Video encode and decode: AMD publishes H.264 and H.265/HEVC encoding and decoding; Sapphire specifies PCIe 3.0 for the named variants
