Geforce GTX 680 reviewed: market position
Nvidia wants to sell the GTX 680 analogous to naming the successor to the GTX 580 and sees it as the logical replacement in the enthusiast sector. This of course means that the direct competitor AMD Radeon HD 7970 and is (unfortunately) and that it is based on the price and the introduction of the GeForce GTX 580th In an e-mail notification with Nvidia announced shortly before the launch that the GTX should cost 680 419 € plus Mehrwersteuer - the tax is of course different in the euro area, the German rate of 19% means that an EIA of approximately 499 euros. First shops like Caseking list their tickets EVGA GTX 680 at a price starting from 479 €. According to the relevant intermediate state of this forum poll (please note that the results of the open survey may have since changed), we opted for this online test the GeForce GTX 680 decided to give you all the important benchmarks in the hand, but dispense with a larger number of comparison cards - we get this in the print edition PCGH 05/2012 to 12 pages.
The memory interface of the GTX 680 is - as a performance chip usual - only 256 bits wide, it combines Nvidia this with faster GDDR5 memory than even the GeForce GTX 580: Our reference model uses Hynix 'R0C-RAM, which according to specifications with 3.0 GHz (6 Gbps) works. Thus, the GTX 680 over the same transfer rate as the GTX 580 On paper gives the GTX 680, the double (not triple) performance of a Geforce GTX 580, the Radeon HD 7970 it is not enough - especially since their double precision throughput is not so heavily curtailed. In theory, the Geforce GTX 680 ergo a greater limitation by its memory bandwidth than the GTX 580 How this works in practice, we'll look at later.
