VTX3D, a brand owned by TUL, displayed the Radeon HD 7770 X-Edition. The factory-overclocked graphics card comes with clock speeds of 1150 MHz core and 1250 MHz (5.00 GHz effective) memory, against reference clock speeds of 1000 MHz core and 1125 (4.50 GHz effective) memory. The card features a red-colored AMD reference design PCB, and a cooling solution that's just cosmetically different from AMD reference design (red and black colors inverted). The card packs 1 GB of GDDR5 memory across a 128-bit wide memory interface. Based on the 28 nm "Cape Verde" silicon, the Radeon HD 7770 packs 640 Graphics CoreNext stream processors.
