2GB GDDR5 Radeon HD 7870 card
The XFX 5.0 Radeon HD 7870 provides 2GB of GDDR5 memory on a 256-bit interface with a 1000 MHz core clock. It targets builders wanting DirectX 11 and OpenGL 4.2 capability for 2560 x 1600 gaming or multi-monitor productivity. Eyefinity and CrossFireX support allow up to four displays or multi-GPU scaling. A dual-fan fansink handles thermal duties.
PCI Express 3.0 x16 with dual 6-pin power
The card plugs into a PCI Express 3.0 x16 slot and requires two 6-pin power connectors fed from a 500 W or larger supply. Outputs include two DVI, two HDMI and two Mini DisplayPort connectors, freeing the builder from active adapters when driving four panels. HDCP readiness enables protected playback. Supported operating systems span Windows 7, Vista and XP.
Sustained load on dual-fan fansink
Under continuous load the dual PWM fans ramp to move heat away from the fansink assembly, keeping the 1000 MHz engine clock stable during extended sessions. The 4800 MHz effective memory clock and 400 MHz RAMDAC maintain consistent frame pacing at 2560 x 1600. PowerTune and PowerPlay technologies adjust clocks and voltage dynamically to balance thermals and performance over long periods.

Questions sur cet article
What is the power draw when the 7870 runs at 1000 MHz all day?
The card needs two 6-pin power connectors and the maker recommends a 500 W system supply, so sustained load will pull close to that limit.
How loud does the dual-fan cooler get during long sessions?
A dual PWM fansink is fitted; fan speed ramps with temperature, so noise rises under load but drops at idle.
Which display cables must I already have for the four outputs?
The bracket carries two DVI, two HDMI and two mini DisplayPort sockets, so you need matching cables for each monitor you attach.
