PRODUCT PICTORIAL & WALKTHROUGH


Let's take a virtual walk around XFX's version of ATI's HD 5830.



First off we start at this videocard's VPU. XFX's use of the 40nm manufactured Cypress core is stock clocked at 800Mhz core, 1000Mhz 256bit DDR5 memory which is bandwidth capable of 128.0Gb/sec memory transfer which is pretty standard for mainstream 256bit enabled DDR5 graphics cards. This coupled with the VPU's 1120 unified shaders is capable of 12.8GPixels/sec and 44.8 GTexels/s while drawing 360 watts during maximum load and 165watts at idle. .


The amount of shader pipeline and clock rates is the main difference other than the core capabilities between it and the HD5870 and the HD5850. The HD5870 has 1600 shader pipelines whereas the HD5830 has only 1120 with the HD5850 falling exactly in the middle. In addition the HD5870 will have an overall higher peak memory bandwidth due to its higher memory clock at 153.6Gb/sec, but the HD5850 and the HD5830 are exactly the same at 128Gb/sec.




XFX chose not to use a reference based GPU cooler that exhausts hot air directly out of the case and instead went with a more basic heatpipe based cooler that will also supply needed airflow to the onboard DDR5 memory below. Although the cooler seems to be enough to keep temperatures down, testing under a full 1920x1200 FurMark stress test load had temperatures reaching 78c before they would stabilize. Just to be sure I removed the cooler to make sure the cooler was making decent contact and all seemed to be well. This cooler just isn't up to the task of keep this videocard cool.


With that being said, the videocard was stable even when temperatures started ramping up to their maximum and no artifacts were seen during stock clock testing.



The back of the card is completely void of any obstruction to interfere with any sort of upper motherboard components and facilitated an easy install. As you can see, this cooling solution was held in place with no less than 4 screws and insures that there won't be anyway that this cooler will be separating away from any of the components it is cooling. Keep in mind that this is a full size videocard and consideration should be taken if you are planning on installing this videocard on a smaller motherboard or case.
