AMD Hardware Review Roundup

Hardware Secrets-MSI Radeon HD 6870 Video Card Review
The name given by AMD to this new GPU family is misleading. Since 6800 is a number higher than 5800, users may think that the two members of this new family are faster than their counterparts from the Radeon HD 5800 family, namely the Radeon HD 5850 and HD 5870, which is not the case. As you can see in the table below, while members of the 6800 family run at a higher clock rate, they have a lower number of internal processors (shaders). This makes members of the 6800 family to be actually slower – but more affordable – than members of the 5800 family.

"The Sapphire Radeon HD 6850 features the second generation of graphics technology from AMD designed to support all the features of Microsoft DirectX 11 and DirectCompute 11. The new GPU’s are built in AMD’s 40nm process to deliver high performance with low power consumption. Advanced hardware features include an enhanced Tesselation unit, dedicated HDR Texture compression, multi-threaded communication with system CPU cores, embedded support for many of the DirectCompute 11 instructions, 3D stereoscopic support and HDMI 1.4a."

Hardware Secrets-XFX Radeon HD 6850 Video Card Review
XFX also has a factory-overclocked version of this video card, called “Black Edition”. In this card the graphics processor runs at 820 MHz and memory runs at 4.4 GHz.

Bjorn3D-VISIONTEK 6870
VisionTek kept the front and back of the card plain and simple: no stickers, no crazy designs, just AMD's plain reference design. The top and bottom of the card have the black and red reference design as well. On the top of the card is additional air venting and two 6-pin PCI-E power connections. For size comparison, the GTX 460 is about an inch and a half shorter than VisionTek's HD6870.

OCIA-Biostar A880G+ AMD Motherboard
Over the last several years Biostar has been offering their upscale T-series of motherboards that feature better components and greater overclocking potential. Aside from the T in the model name, these T-series have also been distinguishable by their blue/orange/yellow color scheme, as opposed to the green/white/black of their standard models. Beginning this year it seems they have switched to using black/red/white for all of their boards, and the A880G+ looks very similar to the TA880G+ in appearance.

Tbreak-ASUS Crosshair IV Extreme review
Based on the AMD 890FX/SB850 chipset, the ASUS Crosshair IV Extreme will support any AM3 based Phenom II, Athlon II and Sempron 100 series CPU. Since this is a Republic of Gamers enthusiast motherboard, packed in along with the instruction manual and the drivers CD is an extra eSATA expansion bracket, 3x SATA 6.0GBps cables, 1x SATA 3 cable, 1x USB cable, rear i/o panel cover and an RoG sticker for your case. There’s also a set of voltage reading cables and three additional temperature sensors for the CPU along with a CrossFire cable added in for good measure.

Tweaktown-GIGABYTE Radeon HD 6850 1GB Video Card Overclocked
Since we haven’t looked at the GIGABYTE version of the HD 6850, we’ll be first checking out the package before we get into the card. Once we’ve done that we’ll have a quick look at the specifications before we go into more detail on the overclock we managed to achieve. With that done it’s time to get into the fun stuff and see what the overclock does for performance. For now, though, let’s check out the package.

Bjorn3D-SAPPHIRE HD 6850 : 1120 SHADER VS 960 SHADER
When AMD launched their Radeon HD6xxx series, we did a review of the Sapphire HD6850. Soon after, we found out that the review sample sent to us contained 1120 shader units instead of the 960 shader units that AMD prescribed for the HD6850. We quickly contacted Sapphire, and confirmed that the review sample did indeed contain 1120 shaders. We did what any reputable product analyst would do, and shipped our review sample back to Sapphire for a retail version of the HD6850 so we could rerun our benchmarks and obtain an accurate result.
