Zotac GeForce 9800 GX2
http://i1.techpowerup.com/reviews/Zotac/GeForce_9800_GX2/images/logo.jpgToday NVIDIA launches the GeForce 9800 GX2. As the name suggests thiscard is a dual GPU design, just like the AMD Radeon HD 3870 X2.Compared to the latter there is a big design difference, NVIDIA usestwo seperate PCBs with one GPU each. This allows much easier signalrouting and helps signal stability allowing higher clocks. As coolingsolution a new ingenious approach is used. The GPUs are facing eachother, with one cooler in between. This helps keep the fan noise down,also the whole card is lighter and is cheaper to manufacture.
When looking at the specs it becomes clear that the NVIDIA GeForce 9800GX2 is really not much more than two 8800 GTS cards glued together andrunning in SLI. What should be noted here is that the GeForce 9800 GX2will work in any system with PCI-Express, an NVIDIA chipset is notrequired for operation.
Zotac's card follows the reference design to the letter, with the onlyexception being a Zotac sticker on the card's cooler. Zotac is workinghard with NVIDIA to release a higher-performance Amp! Edition, but atthe moment NVIDIA does not allow any changes to the card and itssettings.
