GTX 570 vs Radeon 6970 and 6950 vs Radeon 5870 – All Overclocked Review
Gigabyte GeForce GTX 570 – The Card
Our Gigabyte GTX 570 sample arrived in a plain box with no retail bundle. Shown above is the box artwork that consumers can expect to receive. Also shown is the bundle Gigabyte used for their GTX 400 series and the 570 should closely match this, including a free HDMI cable.
For this card Gigabyte have gone with the reference design for the GTX 570 and to make their card stand out from other models the heatsink is covered by some artwork which matches the box. Flipping the card over we can see that Gigabyte cover their SLI connectors with plastic tabs to protect them and the inclusion of two tells us the card can do 3-way SLI.
As Gigabyte has retained the standard dual slot cooling solution this means that underneath the shroud we have a vapour chamber cooler. This uses a copper base, water chamber and aluminium fins to dissipate heat. Also present on the Gigabyte GTX 570 is NVIDIAs power control circuitry which manages the power use of the card, ensuring it only draws the power needed, increasing the lifespan of the product and reducing heat.
For the outputs Gigabyte has gone for two dual-link DVIs and a mini-HDMI which is capable of passing through 7.1 LPCM audio. The GTX 570 can power two displays at any one time and combined with another in SLI, 3 screen gaming is possible. In terms of power inputs two 6-pin connectors are present at the top of the card and supply it with up to 219w.
The core on this model is set to 732MHz, 950MHz is the memory speed and 1464MHz is the shader clock. This is of course on the 480 CUDA cores which connect to the 1280MB of GDDR5 via a 320-bit memory bus. PCIe 2.0, DirectX 11, DirectCompute 5.0, CUDA, PhysX and OpenCL are all supported on this card as is acceleration of high definition content.
For those who need a reminder of the main changes between the 500 series and 400 series, as well as the improved power management NVIDIA also tweaked the transistors uses within the GPU and enhanced the design to maximise performance in areas such as Tessellation.
