HIS announced its Radeon R9 290X graphics card duo, both of which stick to AMD's reference board design, with reference clock speeds of 1000 MHz core, and 5.00 GHz memory; and differ only with the packaging. The HIS R9 290X Fan is the base model, while the HIS R9 290X Fan Battlefield 4 Edition is practically the same card, but with an Origin key to Battlefield 4. The base model is priced at $549.99, while the Battlefield 4 Edition could charge a $25 premium over that (still cheaper than buying the game off Origin). Based on the 28 nm "Hawaii" silicon, the R9 290X features 2,816 stream processors, 176 TMUs, 4 Tessellation Units, 64 ROPs, and a 512-bit wide memory interface, holding 4 GB of GDDR5 memory.
