Video Card


Having a look at the card now, you have to think at first sight that we've just re-used the photo of the HD 5870. Head on the cards look almost identical with the major difference being that this one has HD 5850 on it instead of HD 5870.




The only physical difference from head on which can't be noticed here is that the HD 5850 comes in 9.5" (24cm) which is the same as the HD 4890. It is 1" shorter than the HD 5890 which comes in at 10.5" (27cm). We can of course see that Sapphire has mixed it up in their own way with a sticker.




Looking at the back of the card where we have our two little holes we can see like the HD 5890 this card carries with it two 6-Pin PCI-E connectors. These are instead sitting at the back of the card rather than on top, though.




Speaking of on top, we can see our two CrossFire connectors sitting closer to the front. Here we have the chance to run up to three cards in a CrossFire X formation. While we won't be making use of the connectors today, we will be in the near future.




Moving to the I/O side of things, the setup is exactly the same as the HD 5870. We've got a little vent sitting on the top right with a single Dual-Link DVI connector. Below that we have another one while to the left we have a native HDMI port and DisplayPort. This setup of course gives us the ability to run up to three monitors via two DVI + DP or one DVI and one HDMI + DP.




Let's take a look at how the HD 5850 compares to the HD 4890 and HD 5870. Like the HD 5870 the HD 5850 carries 32 ROPs, up from 16 on the HD 4890, a 256-bit memory bus and 1GB of GDDR5 like the HD 4890. Like the HD 5870 the card utilizes a 40nm manufacturing process, unlike the HD 4890 which uses 55nm.




As far as clocks go, the core comes in at 725MHz which is down from the 850MHz clock the HD 5890 and HD 4890 carries. The memory clock is up compared to the HD 4890 which carries a 975MHz or 3900MHz QDR clock. The HD 5850 comes in at 1GHz or 4000MHz QDR. It is slightly down from the HD 5890 which comes in at 1200MHz or 4800MHz QDR. Like the HD 5890, the card carries with it the ability to run Direct X 11 in supported games.
