ASUS
HD 7870 TOP and HD 7850 TOP graphics cards, based on 28nm AMD
“Pitcairn” GPU technology, deliver a golden median of power, efficiency,
and exclusive features. They utilize factory-overclocked cores that run
significantly faster than reference. The HD 7870 TOP is 100MHz over,
while the HD 7850 clocks at 115MHz faster than stock. Both support
extensive overclocking with cool and quiet ASUS DirectCU II thermal
architecture. Exclusive GPU Tweak allows for easy access to the
considerable power of these cards, while the inclusion of AMD Eyefinity™
multi-screen display, PCI Express 3.0, and DirectX® 11 optimization
completes these offerings, which are sure to become highly popular among
dedicated gamers and multimedia users.
Bringing 28nm graphics to the widest audience
The arrival of ASUS HD 7800 TOP graphics cards extends the benefits
of AMD 28nm GPU technology to the “sweet spot” segment. The new models
offer gamers and multimedia consumers an ideal option that balances
powerful performance with superior value and a complete feature set.
Both HD 7870 TOP and HD 7850 TOP variants ship factory overclocked. The
HD 7870 TOP (reference speed 1000MHz) arrives clocked at 1100MHz, while
the HD 7850 TOP (860MHz) has been sped up by ASUS to 975MHz. These
frequencies offer a better starting point for overclocking and high
intensity applications, and both use 2GB of GDDR5 video memory. The HD
7870 TOP has been labeled the GHz Edition, reflecting its higher speeds
and more overclocker-friendly architecture.
DirectCU II sets new milestones in cool and quiet graphics
Complementing their overclocked TOP status, the two HD 7800 cards
employ exclusive ASUS DirectCU II thermal technology. At its core are
direct-contact copper heatpipes that touch the GPU unhindered for faster
heat dissipation. The custom cooler also uses twin precision-mounted
100mm fans to reduce noise, resulting in cards that operate 20% cooler
and 10dB quieter than reference. Lower temperatures lead to longer
lasting products that are also better suited to overclocking, while
reduced noise helps create more comfortable computing environments.
Easy and accessible tuning with GPU Tweak
Another ASUS exclusive in the box is the GPU Tweak utility, an
extensive and user friendly frontend that allows for clock, voltage, and
fan speed modification with ease. The latest version includes
convenient clock and voltage syncing for safer and more stable
overclocking, 2D/3D mode locking to ensure more accurate benchmarks, and
live BIOS/driver updates to keep cards working at their best.
Multi-screen displays, PCI Express 3.0, and DirectX® 11
Like other ASUS HD 7000 Series cards, the HD 7800 TOP models support
multi-screen AMD Eyefinity™ technology to expand viewing real estate.
The HD 7870 TOP and HD 7850 TOP both enable multi-screen Eyefinity™,
equipped with one HDMI, one DVI, and two mini DisplayPort outs. They
also offer PCI Express 3.0 interfacing, which doubles the maximum
bandwidth previously provided by PCI Express 2.0. As “Pitcairn” GPUs
deliver better optimization for Microsoft DirectX® 11 compared with
previous-generation 40nm GPUs, graphics performance has been updated
with the latest developments for more impressive and detailed gaming.
The HD 7870 TOP and HD 7850 TOP can sustain up to four times the
tessellation capabilities, as well as significantly faster DirectCompute
for better parallel computing output.
