Elder version radeon HD 2600 XT will be equipped with GDDR-4 memory , some AMD partners even promised to place on such video cards 512 mb memory. However, there is no special demand for video cards with GDDR-4 support - Radeon x1950 XTX, for example, yielded its place for cheaper video cards radeon x1950 XT with GDDR- 3 memory .
In our previous news it is possible to reveal references about video card Radeon x1950 pro with GDDR-4 memory , which jetway company demonstrated on exhibition ceBIT 2007 as prototype. Our associates has available copy Of radeon x1950 pro with 256 mb GDDR-4 memory , released by Chinese company YESTON.
In this photograph the GDDR-4 memory is placed on top, in GDDR- 3 version the memory is placed below:
In all video card Radeon x1950 pro there is eight GDDR-4 microcircuits : four are placed in the face side and four with in the back. In this case samsung microcircuits are used with access time 0.9 ns, which allow to overclock the memory up to 2200 MHz DDR.
Although the GDDR-4 memory has a short access time, the default frequencies of this version radeon x1950 pro are increased slightly - from 575/1360 MHz to 600/1600 MHz. The advantages Of radeon x1950 pro is the presence of 256- bit system bus, which is absent in new video cards series radeon HD 2600.
Talking about advantage from passage on GDDR-4 , Radeon x1950 pro in tests showed increase in speed by about 10% in the best case. We should consider that video card with GDDR-4 memory in this case worked at higher frequencies (600/1600 MHz) in comparison with predecessor using GDDR- 3 memory (575/1360 MHz). The presence of GDDR-4 memory will increase the price of video card, and there is no sense to overpay for it. Possibly, overclock could justify passage on GDDR-4..... Related Products :
