WORD IS HITTING the street about the last ATI Evergreen card. The top 5 were recently named, but there is a sixth lurking in the shadows.

The new card is called Trillian, and it is supposed to be at the top of the heap. It is a card name, not a new ASIC, so don't expect any new silicon. Just like Hemlock is two Cypresses on a board instead of a new chip, Trillian is also made up of existing silicon.

The name has some interesting connotations, the first three letters of which are 'tri'. That leaves two interpretations, the most obvious of which is a three GPU board. There have been a few demos here and there of three GPU boards, but nothing that ever made production.

Given that the interconnect on the 3870x2 and 4870x2 are simple PCIe-2 switches, it should be pretty easy to do a three-way board. A 16x PCIe-2 slot is more than capable of providing the needed bandwidth, even with Cypress's immense shader count. This scenario is pretty doubtful though, a 3x Cypress board would run into power limits unless ATI pulled off some serious magic that the TSMC 40nm process seems currently (pun intended) incapable of providing.

The more likely Trillian board is a multi-monitor card that has been spoken about as far back as Computex. Multiple outs fit into existing leaks quite well, but what chip it is based on is quite another question entirely.

...This could indeed be possible, concerning that the RV770 is already quite dependent on bandwidth and the RV870 is expected to have twice the computing power. Also the recent information that the chip would be bigger than 300 mm², affirms the theory of 384 Bit memory interface, because already the dimensions of the RV770 would have made it impossible there...

...Because of the shortly upcoming launch it is hardly due that AMD will use GDDR5 memory on their top cards, which runs faster than 1.25 GHz. So it would be possible to reach a maximum of 240 GB/s memory bandwidth with the 384 Bit memory interface, more than twice as much as the HD 4870 would reach.

...You might have heard rumors of some odd memory configurations going around and a source close to AMD has confirmed this. Numbers are pointing to something like 384-bit and GDDR5 with the high-end X2 part, 192-bit and GDDR5 with the performance part, and then scaled down to 96-bit and perhaps even 48-bit with lower-end parts. The numbers are still pending confirmation, but we are quite confident AMD will bring some odd memory configurations to the market with Evergreen.

Names and specifications are just waiting to be leaked, but so far they are still hard to confirm. It does however look like RV870, Cypress, will sport something in the range of 1600 shaders, 80 texture units and 32ROPs, with RV830, Redwood, at 800 shaders, 40 texture units and 32ROPs and Cedar at slightly less. These numbers are mainly speculation at this point.

However, we did learn at that AMD has a card with performance better than Radeon HD 4850 but consuming less than 75W. We would expect this to be a flavor of Redwood, RV830. Evidently, AMD has mastered the 40nm process and managed to reduce power consumption while maintaining good performance....
