Already on 15 January the GeForce GTX 285 will have to appear officially .
Associate introduced the appearance and construction Of this video card.
We start from the photograph of the old GeForce GTX 280 in comparison with the new one :
As a whole, the differences are noticeable : The optimized power-supply system, all memory chip are placed on one side .
Let us look to the power-supply system:
As it is evident, it underwent significant changes. Moreover, it differs from both : the one used in GeForce GTX 280 and from the new versions GeForce GTX 260. Here we deal with 3+1 power phase, and the arrangement of elements astonishes by its strict directivity. According to the estimation of independent specialists, the realized in GeForce GTX 285 power-supply system as minimum is not worse than the one used in GeForce GTX 280.
The GeForce GTX 285, will be equipped with memory, which works at the effective frequency 2484 MHz. For these purposes is used a new memory from hynix production , with the access time 0.77 ns and calculated for effective frequency 2600 MHz.
Here is the graphic processor:
As it is evident, we deal with the graphic processor GT200b, revision B3 and released on 47 week 2008, which corresponds to 10-16 November. It is worthwhile to focus attention, that this revision was observed only in the GeForce GTX 295, while the GeForce GTX 260 was satisfied by the graphic processors v2. This moves some hope, which are connected with the GeForce GTX 285 overclock.
Besides the construction of printed-circuit board, the construction of cooling system was also updated. In the left we have the cooling system for the GeForce GTX 280, in the center - GeForce GTX 285, and to the right GeForce 9800GTX+:
The length of aluminum plates in the cooling system in the GeForce GTX 285 was decreased in comparison with the GeForce GTX 280, although the number of heat pipes remained before. The copper area in the GeForce GTX 285 also decreased in comparison with predecessors, this is another confirmation about NVIDIA intentions to maximally decrease the cost of its one chip production .
The new card came out noticeably simpler than its predecessor which, most likely, positively will affect it's prices. If we believe to some rumors, NVIDIA plans soon to reduce the price Of the GeForce GTX 285 to $299. Related Products :
