The second new factory-overclocked graphics card to be shown by VTX3D at Computex, is the HD 7870 X-Edition. Unlike the HD 7770 X-Edition detailed earlier, the HD 7870 X-Edition comes with true non-reference PCB and cooler designs. The cooler appears similar to the one PowerColor (a sibling brand of VTX3D) used on the HD 7870 Eyefinity6. The card comes with out of the box clock speeds of 1100 MHz core, and 1225 MHz (4.90 GHz effective) memory, against reference clock speeds of 1000 MHz core, and 1200 MHz (4.80 GHz effective) memory. Based on the 28 nm "Pitcairn" silicon, the HD 7870 packs 1280 stream processors, and holds 2 GB of GDDR5 memory across a 256-bit wide memory interface.
