A Look at the ATI 5000-series


[

As you can probably tell by the chart above, all of the HD 5000-series fit perfectly into ATIís lineup. At the top of the heap we have the ultra high performance dual GPU HD 5970 which carries most of the same specifications as a pair of HD 5870s. There are however some sacrifices that had that had to be made in the clock speed department in order to keep power consumption within reasonable levels. So, while this card has the same number of texture units and stream processors as the HD 5870, its core and memory run at speeds identical to the HD 5850.

Judging from paper specifications alone, the HD 5870 is a technological marvel considering it packs all of the rendering potential of ATIís past flagship card and then some while not being saddled by an inefficient dual processor design.


The HD 5850 on the other hand is the purebred price / performance leader of the new ATI lineup. Barring slightly lower clock speeds for both the core and memory along with eight disabled texture units (totalling 160 stream processors), it is basically a clone of the HD 5870. This is the card ATI hopes will compete directly with the GTX 470 for the near future and believe this card will appeal to the majority of people since it allows them to buy class-leading DX9 and DX10 performance now without gambling $400 on somewhat unproven DX11 potential.

ATI has positioned their HD 5830 between the HD 5850 and HD 5770 but as we know by now, its performance is closer to that of the lower-end card and there really hasnít been much to allow this card to distinguish itself. Itís price coupled with lower than expected performance make it the least appealing card in the linup.


Meanwhile, we have the HD 5700-series of code-named Juniper cards as well with the HD 5770 and HD 5750. The HD 5770 1GB is one of the first sub-$200 cards which will come stock with 1GB of memory and along with the GDDR5 memory, comes with some hefty clock speeds as well. However, even though upon first glance the HD 5770 looks like it can compete with the old HD 4890, this isnít the case. According to ATI, the 128-bit memory interface will limit this cardís performance so it lies right within its stated price range.

The HD 5750 on the other hand is simply a cut down HD 5770 with lower clocks, less SPs and a cut down number of Texture Units. It is this card that ATI sees going head to head with the NVIDIA GTS 250 and 9800 GT. It uses GDDR5 memory but there will be both 512MB and 1GB versions released to cater to the $100 market along with those looking for a little jump in performance.
