Mobile Fudo goes after Go 7800GTX
Battle of the mobiles brewing
AS ATI preps the launch of its late Fudo-based mobile monster, the information about the product has begun to leak.
It seems that Mobility Radeon X1800XT series will be clocked slower than the clockspeed of its desktop brother, and the amount of video memory will be XL-, not XT-like, 256MB GDDR-3 on-board memory.
The desktop range will get a refreshment at the end of January, with the launch of Radeon X1900 series (X1800 will be replaced with X1900). The mobile world will get a product "one semi-generation behind" in the form of a Mobility Radeon X1800 range -unless ATi's marchitecture department gets involved in creative name-gaming.
The lower clockspeed on the mobile part isn't a surprise. Due to thermal issues on designing the mobile package, the clock limits are usually ranged at 500MHz for both the core and the video memory chips. ATi couldn't keep the mobile baby at 500MHz with good thermals, so the core works at 445 MHz, while the memory is ticking over at 495MHz DDR, delivering 31.68 GB/s of memory bandwidth.
Nvidia's GeForce Go 7800GTX 256MB already has a GPU clocked at 400-440 MHz and the memory is somewhere in the 500-550MHz range, depending on notebook manufacturer. It will be interesting to see how ATi's chip stacks up against it. µ
de certeza que compras um desktop bem mais potente por esse preço
