Gigabyte GV-R587SO-1GD Radeon HD 5870 Videocard Review
Gigabyte GV-R587SO-1GD Radeon HD 5870 Videocard Review - PCSTATS
Gigabyte's GVR587SO-1GD videocard increases the Radeon HD 5870's core clockspeed to 950MHz, the effective frequency of its GDDR5 memory to 5GHz. This beauty of a videocard uses a custom dual-fan heatsink design for better cooling and takes advantage of Gigabyte's Ultra Durable VGA+ manufacturing techniques.

GPGPU Videocard Benchmarks: Sandra 2009

SiSoft Sandra 2009 - GPGPU Processing Source: Sandra

Sisoft's Sandra's GPGPU (general purpose graphics processing unit) benchmark analyzes the ability of the GPU to perform Mandelbrot equations to generate fractals. These same types of equations are used in tasks like image processing, video encoding and scientific simulations, giving an index of how well a GPU can perform in this test.

ASUS ENGTX480 2DI/1536MD5 151.8

The Gigabyte GVR587SO-1GD videocard has what it takes to make it as a GPGPU device, with better scores overall for both its floating-point shader performance and its double precision shaders performance as well. Given that this is some very new technology its likely that NVIDIA's lack of performance here is due to a less than optimal test configuration, rather than a failure of its CUDA technology.

The second part of Sisoft's Sandra's GPGPU measures the videocard's memory bandwidth, which will directly affect the overall performance of GPGPU applications.

The numbers here are much more in favor of the Geforce GTX 480, which edges out the Gigabyte GVR587SO-1GD's overclocked memory performance. The Gigabyte GVR587SO-1GD has faster GDDR5 memory (5GHz vs. 3.7GHz), but a narrower memory bus interface (256-bit vs. 384-bit), which tips the scales in NVIDIA's favor.
