AMD Radeon HD 7870 And 7850 Review: Pitcairn Gets Benchmarked

Benchmark Results: Sandra 2012

Let’s move on to compute performance. Sandra 2012 provides some convenient OpenCL benchmarks for us to compare, so let’s start with general purpose processing:

The Radeon HD 7800 series’ floating point performance is exceptional, though double-precision throughput is significantly lower than the 6900 series.

The new Radeons enjoy less memory bandwidth (called internal bandwidth by Sandra) than the 6900s.

However, PCI Express 3.0 compatibility facilitates significantly more throughput between our 7800-series cards and our Sandy Bridge-E-based test bed compared to the PCIe 2.0-capable 6900s.

    The Radeon HD 7800s don’t do particularly well in World of Warcraft, finishing behind their respective predecessors, albeit just slightly. More importantly, they succumb to the comparable GeForce cards they’ve been matching pace with up until now.


    WoW favours Nvidia hardware over ATi, its always been this way.

    still no absolute reason to change from my 5870... come on amd thats 2 generations of cards and neither have given a significant enough increase to warrant a replacement.

    That's the problem with annoying bots like fufuss.. they can't see benchmark graphs.
