nVidia and Turbocache! – Huh? What on earth is that..

One benefit of PCI-Express, was the fact the interface was so fast, that the card could actually utilise the main system RAM, as well as the onboard Graphics RAM, this meant less money spent on large amounts of fast RAM, so cheaper cards, but in theory no loss of performance as a result. However many reputable internet reviewers slammed this concept as misleading to the consumer, and prompted nVidia to change the name.

Truth be told, this concept was not a new concept. As far back as the early ninties the idea of leaching system RAM to power a graphics card and share the load was put into practice, it dramatically reduced costs – but the bottleneck between the GPU and the system bus was so constrictive – but now with PCI-X and its 4GB/s Bandwidth between it and the Core Logic and the Graphics Processor, its again a reality that might just work well.

The buzz word, TurboCache refers to the graphics memory on the GPU, which acts as a supporting frame buffer, and a software managed cache allocation area. Now according to the 6200 cards with Turbocache are up to 25 percent faster than an X300 SE, and legend has it 50 percent faster then the X300 LE’s.

Now the fly in the medias eye was that nVidia planned to retail the cards as ‘GeForce 6200 w/ TurboCache supporting 128MB @ 10.8GB/s’, which was deemed highly confusing, so at last minite they decided to remarked as ‘GeForce 6200 TurboCache 16-TC/128MB’ which admittedly is alot better, but people should be very careful of ensuring just how much physical RAM is onboard the card, and the actual bandwidth of the onboard RAM.

A nVidia spokesperson from San Jose did say thats its very unlikely cards with the old name will hit the shops, but there is still a possibility. We should expect to see these cards hitting the US anyday now, and the UK perhaps just after Christmas.
