 Hitachi today released a new 2"1/2 drives range for laptops, the 4K120. These hard drives are the first, for this manufacturer, to reach 120 GB. Based on two 60 GB platters for the 120 GB version, these products are already available for OEMs and will hit the shops in August.
With the 4K120, Hitachi is the third one to reach 120 GB with this type of hard drive. Fujitsu announced the MHV2 AT in March and Seagate the 4200.2 & 5400.2 in April. Like Fujitsu and unlike Seagate, this drive spins only at 4200 Rpm. The counterpart for Hitachi is the drive lower power consumption and highest resistance to impacts with it is switched off (1000G for 1ms as compared to 900 generally for other products).
We also remind you that 2"1/2 drives capacity should seriously increase at the end of the year with the release of the perpendicular recording technology. The drive capacity should reach up to 160 GB with two platters. |

 According to DigiTimes, AMD will release a new more affordable Athlon 64 X2 simultaneously to the Sempron processors price cut expected early August. The processors P-Rating would be 3800+, and the unit price $345 as compared to $537$, $581, $803 and $1001 for the 4200+, 4400+, 4600+ and 4800+ versions.
If we follow the P-Rating method used for the previous processors, we may think that the A64 X2 3800+ will feature two cores clocked at 2 GHz with 512 KB of cache L2. This processor P-Rating is identical to the A64 3800+, but this processor only has once core clocked at 2.4 GHz with 512 KB of cache. |

 Following an update of Riva Tuner to support the 7800 GTX, some user have noticed the CPU frequency increase from 430 MHz to 468 MHz in 3D.
Guru3D asked the question to NVIDIA and this is the answer: the 7800 GTX is initially clocked at 430 MHz, but NVIDIA has increased the chip’s complexity on the frequency level. NVIDIA is currently working with Riva Tuner for the software to read the good register and report the right frequency.
Does this means that the GeForce 7800 GTX works with several frequencies? It is probable that it does. Also a few days ago we could read on one of NVIDIA’s partners product page: “Shader Clock 430 MHz/Rop Clock:430MHz/Geometry Clock:470MHz” This page has strangely been modified. If this information is true, it would mean that several different frequencies are used for geometry rendering (triangle setup & vertex pipes) and for the other parts of the GPU. So, gains measured with the vertex shaders during our test wouldn’t come from an increase of the unit efficiency but because of a higher frequency.
Of course, the final result is the most important, but we still wonder why NVIDIA hasn’t officially communicated on the subject. |

During a seminar in Tokyo, the DVD+RW Alliance announced to work on a DVD+RW dual layer media type (which means rewritable) to be available at the end of the year. The initial media write speed will be 2.4x.
 For other standard, nothing seems to be currently planned beyond 16x for DVD+RW. The DVD+RW write speed should be increased over 8x (available since a few months ago) in 2006. The DVD+R DL write speed will also increase beyond the recent progression to 8x. None of the final write speed have yet been communicated. DVD format continues to evolve even if these modifications seem to be the last ones. Indeed, in the months to come manufacturer will focus most of their R&D department on the HD - DVD and Blu - ray disc format development. |
