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.

Eye of the Tiger: ATI Radeon RV870 Cypress GPU

All of ATI's Radeon 5000-series videocards draw from a family of GPUs called 'Evergreen', which is then divided into a smaller GPU lines based on performance.

The fastest line is code named 'Cypress', which is itself broken up into smaller segments based on speed tolerances and how many functional shader processors. This is a practice called "binning" in the tech industry.

Only the 'Cypress' chips that have all 1600 stream processors functioning properly and are completely stable at 850MHz are used in Radeon HD 5870 graphics cards.

The RV850 'Cypress' GPU is produced on a 40nm production process that ATI first introduced in the Radeon 4000-series. Getting down to a 40nm process was important because the Radeon HD 5870 has 2.15 billion transistors on a 334mm2 die, more than double that of last generation's RV770, which had 956 million transistors.

This wealth of transistors comprise the Radeon HD 5870's 1600 stream processors, 80 texture units, 32 raster operators and the 256-bit wide memory interface that connects the RV870 GPU to its GDDR5 memory.

Stock Radeon HD 5870 videocards have 1GB of GDDR5 memory clocked at 1200MHz, however Gigabyte has bumped this speed up 1250MHz, which is then GDDR5-quad-pumped up to an even 5GHz.

All of AMD's Radeon 5000-series of graphics cards share a number of new technologies, the most important of which is support for DirectX 11. This latest revision to Microsoft's graphics hardware standard brings two major additions to the DX11, tessellation and compute shaders.

Tessellation is a method of adding density and complexity to a 3D mesh. It can take a simple, low-poly model and break up the geometry into more complex portions, adding another layer of detail on top of a mesh. The end result is better looking, more detailed graphics with a very low cost in performance.

Compute shaders allow DirectX 11-based GPUs to do tasks normally reserved for CPUs. This will play a big role in desktop applications that harness the power of a PCs videocard, as well as enable games programmers use the GPU to compute things like physics and AI. Again, this opens up the possibility for more immersed gaming, but with a miniscule performance penalty when compared to using a CPU. Now let's see just how well ASUS' EAH5850 DirectCU TOP stands up to a little overclocking... but first, power draw.

Videocard Power Consumption

Here's how this videocard stacks up in real life against a various other videocards for power draw. PCSTATS measures total system power draw and compares that in 3D loaded (max value recorded in 3DMark06) and idle states (at Windows desktop). The power supply used in each test is an A-PFC compliant PC Power and Cooling 750W model.

Even with factory overclocking, more transistors and more shader processors than any other single-GPU videocard in this chart, Gigabyte's GVR587SO-1GD videocard is actually quite energy efficient thanks to be produced on a 40nm production process. The videocard draws 217W under load, less than a Radeon HD 4890. At idle power draw is 109W for the entire test system, which is closer to what you find from economical low wattage videocards, rather than the power guzzling extremism you'd expect from high end videocards.

This frugal power consumption bodes well for overclocking, and its time to see how far PCSTATS can take Gigabyte's cherry picked RV870 GPU...
