3DMark11 Performance Preset – At 720p resolutions where things are more cpu bound, the ASUS excellent overclocks helped the HD7850 to catch up with its more illustrous brothers, even beating the significantly more expensive HD 7950 (which was at stock of course).
3DMark11 Xtreme Preset – No fairy tales here at 1080p, but the high frequencies does help the comparatively cheap HD 7850 to make a better impression of itself.
Unigine Heaven 2.5 and Game Tests – When tested at 2560×1600 (to eliminate any CPU bottleneck), the superior fillrate and memory bandwidth of the HD7970/7950 helps them to pull away from the rest. Again with the overclock, the ASUS card beats the stock HD7870 and even threatens the GTX580, which today costs almost US$100 and US$200 more respectively.
In our GPGPU test, it becomes a test of raw compute muscle. The GTX 580 performs badly because double precision floating point, some parties speculate, is deliberately castrated to protect Quadro/Tesla sales.
The ASUS HD7850 does consume abit more power than the reference card, probably due to a less efficient VRM design and its stock overclock.
