The tentative characteristics of videokart of series GeForce 7800 gtx already filtered into the network, and their origin left not so many occasions for the doubts about their authenticity. Finally, the first models G70 will be shown already on exhibition Computex 2005, and the technical description of videokarty GeForce 7800 gtx already must be formed. Today we had the capability not only to be convinced of the authenticity of the characteristics given earlier, but also to publish the photograph of videokarty GeForce of 7800 GTX standard designs. To this point program we will return only later, and let us thus far examine some characteristics, which require refinement. First of all, it should be noted that the frequency of memory for videokart GeForce 7800 gtx thus far is not determined finally. Nevertheless, capacity (38.4 Gb/s) and word length of the tire of memory (256 bits) has already been mentioned. After using the existing procedure, we can determine the frequency of memory - she will be equal to 1200 MHz DDR. in this case many of the associates they declared, that these videokarty will be completed by the memory, which works at the frequency of 1400 MHz DDR. Most likely, such readings are dictated by economic considerations - for achievement of the frequency of 1200 MHz DDR it suffices to use the existing chips Gddr-3 with the access time 1.6 ns. For the subjugation of boundary 1400 MHz DDR will be required more expensive memory with the access time 1.4 ns. But now represent that this memory on one videokarte of entire 512 mb. - not the cheapest version is obtained, even if we use 1.6 ns chips. Furthermore, 512 mb. version GeForce 7800 gtx can have the lower frequency of memory - similar differences we already observed based on example GeForce 6800 ultra. The fact that 512 mb. version GeForce 7800 gtx will exist, to doubt barely it is necessary. They became known that GeForce 6800 Ultra 512 mb. to the autumn will yield the place for videokarte of class GeForce 7800 gtx, which at the moment of announcement will cost so many, i.e., approximately $800-900. From the early communications we know that 256 mb. version GeForce 7800 gtx will cost $549. Therefore, on the market will be present two modifications GeForce 7800 gtx, which are characterized by the storage capacity. Chip G70 will be allotted by 24 piksel'nymi conveyors and 8 by apical processors. This to third is greater than it is worth hope in NV40/NV45. that together with the increased with 400/1100 MHz to 430/1200 MHz frequencies this will ensure a good advantage on productivity level. It is important that the cost of the solutions of series GeForce 7800 will be gradually reduced, and in autumn they will already be ready are ready to extrude videokarty of class GeForce 6800. A similar substitution has completely obvious economic reasons - chip G70 is produced on the more advantageous 0.11 m to technical process, while NV40 and NV45 they continue to use old 0.13 m a technical process. Furthermore, NV45 uses still and integrated transitional bridge HSI, which additionally increases the cost of chip. G70 will possess the innate support PCI Express x16. in the course of time in family GeForce 7xxx they will appear and videokarty with interface AGP 8x, which use the transitional bridge HSI. Finally, let us switch over to the study of the photograph of standard videokarty GeForce 7800 gtx:
