Meanwhile, the same RV630 core present on all the Radeon HD 2600 cards, along with the exact same number of stream processors, texture units and other graphics hardware, are all found on this card. The GDDR4 version we're taking a look today comes with Samsung chips that are rated at 0.9ns that allow them to handle the high speeds and at the same time be more power efficient.
Since we have already looked at the budget Radeon HD 2400 XT and an overclocked Radeon HD 2600 PRO, it was about time to give some attention to the top model of ATI's new mainstream contingent, the Radeon HD 2600 XT.Īs the highest clocked member of the Radeon HD 2600 family, the XT comes with GDDR3 or GDDR4 flavored memory with a maximum rated speed of 2200MHz DDR. Together with competitive prices that place these Radeon HD cards into lower price brackets compared with NVIDIA's corresponding products (though it could be argued that there is no longer any direct comparison between the two since the ATI cards have looked to be slower in benchmarks), ATI could yet do reasonably well in the mainstream segment where 3DMark scores are not the most important criteria. Whether that is enough for consumers remains to be seen. Instead, what these cards bring to the table are other, less talked about, though perhaps equally important aspects of a modern graphics card, like its dedicated universal video decoder (UVD) engine and significantly lower numbers for noise, heat and power consumption compared to previous ATI GPUs. Despite the initial optimism generated by news that these cards were using 65nm cores, 3D performance has turned out to be rather disappointing. To sum up our outlook on these products so far - if you are hoping that these cards will be the saviors that some ATI fans have been fervently praying for, look away. Much has already been said and written regarding ATI's new mainstream DirectX 10 graphics cards, the Radeon HD 26 series.
