Boost clock	1,340 MHz or –	1,075 MHz
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.	Reference main figures follow NVIDIA's retained 900-series table. Photo shows MSI's reference-style GTX 980 Ti 6GD5. The first-sale date comes from TweakTown's contemporary coverage, which explicitly states announced and released June 1; the original maker launch page is retired.

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.	1000 MHz; NVIDIA lists 1075 MHz boost, while MSI's GTX 980 Ti 6GD5 datasheet lists 1076 MHz.

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 Sapphire's original 4 GB power is only stated as less than 225 W, so its numeric power remains unpublished.	7 Gbps GDDR5; MSI lists 7010 MHz effective memory speed. Numerical bandwidth omitted because the maker sources used do not publish it.

Display outputs
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.	3 × DisplayPort 1.2, 1 × HDMI and 1 × dual-link DVI-I (MSI GTX 980 Ti 6GD5); MSI's datasheet does not state the HDMI version.
Maximum resolution
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.	–
