Architecture
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.	84 compute units, 192 ROPs; game clock 2000 MHz; 58 billion transistors

Base clock
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 detail
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 Sapphire's original 4 GB power is only stated as less than 225 W, so its numeric power remains unpublished.	GDDR6 at up to 20 Gbps; AMD quotes up to 2900 GB/s effective bandwidth with Infinity Cache
