The new video card from Nvidia, code named Titan wearing, would be a solid amount of memory on board. The GeForce 780 would 6GB of gddr5 memory which allows Nvidia to the amount of memory compared to AMD’s flagship doubles.
According to a Swedish website is Nvidia’s GeForce Titan is equipped as standard with three times as much as the standard amount of gddr5 memory for the GTX680 and twice as much as competitor AMD with its topkaarten supplies. The Titan, having on board the GK110-gpu, should that amount of memory can use due to the gpu architecture, which is based on the Tesla K20X cards. The GK110-gpu consists of 2880 cuda cores, divided into fifteen smx-units, which are about 1.5 MB of l2 cache. The gpu is via a 384bit wide bus connected to the memory, that is 1.3 GHz clocked.
In the Titan-gpu, however, would ‘only’ 2688 cores are activated. That is about seventy percent more than the number of cores in the GK104 of the GTX680. The performance of the Titan should be a lot higher and that of the GTX690 to 85 percent approach. The clock speed of the Titan cores would 732MHz much lower than the over 1.2 GHz of the 680, which contributes to the relatively low tdp of 235W. To 6GB of memory to realize, would be a part of the required 24 memory chips on the back of the pcb can be placed. The Titan is around the end of February is expected and would be around the $ 900 cost.
The current topkaarten from Nvidia, the GeForce GTX680 with on board the GK104, Nvidia’s referentieontwerp with 2GB of video memory supplied. The GTX 690 with two gpu’s is, of course, with twice as much memory, but some manufacturers also have the GTX680 with 4GB or even 6GB memory equipped. AMD gives his top model, the Radeon HD 7970, standard 3GB of gddr5 memory. Also on this map are variants known with 6GB memory and with two Tahiti XT-gpu-equipped Radeon HD 7990 cards also have 6GB of onboard memory.
