AMD introduces DirectX 11 graphics chip ATI Radeon HD 5830 before
Video cards using the high-end GPU will be available in 5830 for around 230 euros. The chip works with a core clock of 800 MHz, the memory at 1000 MHz. The performance suffers significantly due to numerous architectural limitations.

AMD today officially introduced the ATI Radeon HD graphics 5830th With the GPU, the manufacturer completes its high-end portfolio with the single GPU models 5870 and 5850 downwards. While the two fastest solutions for 360 euros (Radeon HD 5870) and 250 (Radeon HD 5850) are available, will cost graphics cards with the Radeon HD 5830 about 230 euros.
The Radeon HD 5830 differs from the faster models by the number of computation, texture and raster operation units (ROP). Instead of 1600 stream processors, and available on the fastest graphics chip (Radeon HD 5870), uses the 5830 only 1120 units. The HD 5850 features 1440 stream processors.
However, due to the GPU clock of 800 MHz with 5830 only slightly below the top model with 850 MHz and higher than that of 5850 with 725 MHz. The faster the chip clock reached only by a voltage increase, which is the reason for a slightly higher power consumption at full load compared to the HD 5850th
The raster operation units are limited to 16 in 5830, while have the two fastest variants of the 5800er-line over twice that number. The architectural limitations affect the performance of graphics chips considerably. Thus, the texture fill rate is of 5830 with 44.8 GTexel / s compared to 5850 with 52.2 GTexel / s and 5870 with 68.0 GTexel / s significantly lower. The pixel processing power suffers from the circumcisions: while the top model one Pixelfüllrate GPixel of 27.2 / s and offers 5850 to 23.2 GPixel / s comes, must be content with only 12.8 of the 5830 GPixel / s. Thus equipped the 5830 5770th in this discipline is not even the power of 100 euros cheaper HD
Which are compared to the fastest models in the lower 5800er Series theoretical performance values of an adverse effect in practice. Thus, the Radeon 5830 in game tests achieved significantly lower performance than the little more expensive Radeon HD 5850th Even the Nvidia Geforce GTX 260 is the Radeon HD 5830 in some tests outperform. The available starting from 170 Euro model DX10 ATI Radeon HD 4890 offers the HD 5830 also in many cases, stand up.
In total, the ATI Radeon HD 5830 with a price target of 230 euros for ambitious players to little power. Radeon HD 5850 graphics cards cost only 20 euros more and offer much higher performance. provides for the standard user who place heavy emphasis on DirectX 11 graphics cards, but not as high demands on the performance, the 5770 and 5750 models are better. The latter are available from 110 Euro.
Nvidia can not currently come up with similar solutions. First DX11 models of AMD’s competitor will introduce in late March. The market launch is expected to recent rumors that move but up in May.
The ATI Radeon HD 5830 AMD completes its high-end portfolio with the single GPU models 5870 and 5850 downwards. Because of numerous architectural limitations made the chip, however, significantly less performance than the top models of the 5800er series.
