Nvidia's Fermi: performance of the GeForce GTX 470 unveiled
Nvidia graphics cards still have Fermi end of March in coming, but heise available online exclusively first benchmark values of a prerelease version of the GeForce GTX 470th Accordingly, the DirectX-11 graphics card in 3DMark Vantage is more powerful than 5870th between the Radeon HD 5850 and HD To reach the GTX 470 in 3DMark Vantage (X-Mode) 7511 points, a Radeon HD 5870 with 8730 points, more clearly. , A HD 5850 stood at 6430 points, which reached GeForce GTX 285 in the same test system, 6002 points. The Performance preset shows a similar picture, however, is the Radeon HD 5870 (17303), only slightly ahead of the GeForce GTX 470 (17156). A Radeon HD 5850 reached 14,300 points.
Especially interesting are the results of the Unigine benchmarks, based on DirectX 11 and uses tessellation. Nvidia announced in advance, would be the Fermi-enabled graphics cards, the HD-Tessellation 5800er cards significantly outperform. This we were able to adjust the preliminary benchmark results on the CeBIT in Hanover. Thus achieved at a fourfold anti-aliasing, the GeForce GTX 470 averaged 29 frames per second (fps), a Radeon HD 5870 around 27 fps, the HD 5850 only 22 fps. At eight times the anti-aliasing, however, the performance of the GeForce GTX 470 breaks strong. Then reached only 20 fps, a Radeon HD 5870 is just under 23 fps faster, the Radeon HD 5850 (19 fps) is subject only slightly.
Also in the BIOS of the preliminary test card, we were able to take a look. The shader cores were running with 1255 MHz, the GDDR5 memory, with only 1600 MHz (read-write clock). Nvidia seems much slower than AMD's memory tact, which is similar but by the higher number of data lines again. However, the specifications of the card are not yet final, therefore the test results can also enjoy with caution, in the 3D performance, however, no major changes more likely.
Currently, even rumored to be that the graphics chip, the GeForce GTX 480 will not have the full 512 shader cores. Even Nvidia would not confirm to us in conversation that the GTX 480 actually has 512 cores. Thus, it was pointed out that it had presented in January, although the GF100 at full expansion (ie 512 cores), but had never explicitly announced that the GeForce GTX 480 actually has this number of cores. In fact, Nvidia has for some time after the architectural idea in January, only the names of the first two high-end graphics cards announced.
Clarity, it will be until the 27th Give in March, when Nvidia said it will officially launch the card. Nor even appear to board partners are not much about the upcoming cards to know what some manufacturers were upset. So Nvidia will inform his partner until next Monday on the final specifications, the first cards to arrive two weeks later in their camps. While some partners were already confident that quite sufficient quantities of the new cards from the 29th March will be out of stock. Concerned about them, but the price / performance ratio.
