With the 5000 series from ATI having solidified itself in the market over time due to the performance leads over NVIDIA, manufacturers have come forth with more exotic video card designs and speeds. The 5700 cards are equipped with the second most powerful GPU core, Juniper, which targets the midrange market and is available on the 5770 and 5750. The strongest core is the Cypress, which power the 5970, 5870, and 5850 designs. Both cores are built on the 40nm fabrication process and share a similar design, although the Juniper is virtually half a Cypress with half the stream processing units, ROPs, memory bus, and close to half the amount of transistors, die size, and pixel/texture fill rates. However, both can come paired with 1GB of GDDR5 and have similar clock speeds. Half the size means that these cost ATI a whole lot less and should result in better binning and yields in comparison to the Cypress core, as more Juniper cores can be produced per wafer, not to mention a smaller design is also easier to produce.New variants have been pumped out by many of the manufacturers supporting ATI for some time and PowerColor has just designed a new video card based off of the 5770 PCS+ that was reviewed here at OCC a few months ago. The new design is called the 5770 PCS+ Vortex and sports a new heat sink design and higher core overclock of 900 MHz. One of the things that stands out over most heat sinks is that this one has a movable fan that can possibly operate more efficiently if the system has enough room - with the fan in the normal position, the card only takes up two slots, while with the fan extended it protrudes into a third slot. Overclocking headroom could be limited from the decent factory overclock, but that will have to wait until later on in the review!
