How is ATI Radeon HD 5000?

[KojaG]

Hi all, I have recently registered into this forum. So I am not having much ideas about posting new threads. Still I am trying best to post, and expecting that you people will help me back by providing some proper information. I am getting (from cousin) a video card of ATI Radeon HD 5000 series. Since, she is also not aware about the exact model, I want to know about the ATI Radeon HD 5000 series. Please provide some information about it.

Radeon HD 5970, Radeon HD 5870, Radeon HD 5850, Radeon HD 5770 and Radeon HD 5750 is the current DirectX 11 line-up of ATI, which is prolonged in the upcoming in order to address further price segments. Up to now, remained unprocessed for example, the performance of the Radeon HD 5000 cards under the new operating system Windows 7, which we hereby want to make up. In totaling, we look at the Blu-ray playback that is regrettably up to now have remained entirely overlooked. Windows 7 is for the complete Radeon HD 5000 series is a very significant operating system. And the reason is to be required almost solely in the DirectX 11 API, although it is just for Windows Vista, but is connected primarily with the recently released software. In addition, ATI promises to enhanced the performance of its products on Windows 7 is to be than on Windows Vista.

While it certainly does not like to hear ATi, already a cursory glance shows on technical images: the "new" RV8x0 architecture differs only in detail from the older RV7x0 derivatives. There have of course some major improvements such as support for DirectX 11, Eyefinity and the use of two instead of one rasterizer. Besides, the RV870 is primary but "only" a double RV770, the memory interface has remained the same size. This relationship allows us to play around with the clock rates and to study so, what to bring, for example, the 20 instead of 10 SIMD units to the buyer. As a test candidate at this point have a Radeon HD 5870 and a Radeon HD serve 4890th Apart from the standard frequencies (850/1.200) we overclock the Radeon HD 5870 still in three other constellations. So we leave, among other things, the GPU frequency to the normal level, the memory clock, however, from lower to 1,950 MHz. This would be the memory bandwidth equal to that of the Radeon HD 4890 Thus, for control, how far does the extra speed of the new Radeon card from the higher memory bandwidth.

One can say with a guarantee: The Radeon HD 5870 (and thus probably most of the rest of the Radeon HD 5000 series) is not, interestingly, memory bandwidth limited. And, when the same has been raised to the new Radeon HD 5000 cards compared to its predecessors by far the lowest. ATi himself claims that have the Radeon HD 4890 and Radeon HD 4870 memory bandwidth in abundance, that the GPUs actually hardly know how to do something - our tests back this up. Without anti-aliasing and anisotropic filtering, the Radeon HD 5870 will benefit only nine percent of the additional bandwidth. In addition, we leave the GDDR5 memory at 1,200 MHz, the computing core overclock but down to 425 MHz. Thus, the majority of elements such as theoretical arithmetic and texture power equal to that of a Radeon HD 4890 Only twice the rasterizer and the double-Hierarchical Z units are still an advantage for the Radeon HD 5870 Finally, we have the Radeon HD 5870 are 425/1.950 MHz with the tests, which should theoretically mean an almost identical performance of the GPU generation.
