Although Nvidia’s GeForce GTX 295
looks like a single unit with a huge cooler, anyone who’s seen the insides of one will know that the card’s two GPUs are in fact mounted on separate PCBs. Unlike the Radeon HD 4870 X2, the GTX 295 really is two graphics cards sandwiched together, but the word is that Nvidia is working on a new version of the GTX 295 that mounts the two GPUs on a single PCB.
According to Expreview
, Nvidia plans to launch a single-PCB implementation of the GTX 295 in a couple of months. The site has a picture of the reference design for the card (right), which it says has a PCB design codenamed P658. Comparatively, the codename for the original GeForce GTX 295 PCB was P656, says the site.
In terms of size, Expreview reports that the length of the PCB remains at 266.7mm, and that card’s clock speeds will also be the same as the original GTX 295. The site also notes that the card will feature eight-pin and six-pin power connectors, which was the same configuration on the original card.
There’s no word about whether the new GPUs will be fabricated on a 40nm process, however, which could result in the GPUs putting out less heat and consuming less power. The backplate design also appears to have changed slightly, with the DVI connectors now on the left rather than the right. The main advantages of the new PCB appear to be a simplified design that will be cheaper to manufacture and easier to cool efficiently, although Expreview claims that the price of the GTX 295 won’t change with the introduction of the new PCB.
According to Expreview, engineering samples of the new GTX 295 will be finished in April, and the finished cards will be officially launched in May. If this rumour is to be believed, would the single-PCB design make more sense than the original two-PCB design? Let us know your thoughts in the forums
