 DisplayPort version 1.2
  Posted on 1263214489 by Benoit

The Video Electronics Standards Association (more often called VESA) has just announced a new version of DisplayPort, now in v1.2. This version succeeds 1.1a, used in particular by Apple.

DisplayPort 1.2 doubles bandwidth from 10.8 GB/s to 21.6 GB/s. This will be particularly useful for multi-streaming (several independent audio and video signals transiting via the same single cable). This means, for example, you can connect two 2560x1600 screens @ 60Hz or four 1920x1200 screens via the same socket.

This may well be useful in the framework of high res 3D screens. You can therefore go up to 240 fps with DisplayPort 1.2 at 1920x1080, or 120 fps per eye! NVIDIA’s 3D Vision requires a minimum of 60 fps per eye so there’s something to play with here…

Lastly a USB 2 or Ethernet flow can also be channeled with this cable at a rate of 720 Mbps, as against 1 Mbps with DisplayPort 1.1a.

DisplayPort therefore continues to develop. Time will tell if it is as successful as the DVI or HDMI ports.




 CES: Micron’s C300 SATA 6 Gbps SSD
  Posted on 1263183145 by Damien

Gigabyte was using the Micron RealSSD C300 in its suite to leverage SATA 6 Gb/s. Based on the Marvell controller (the first to natively support this standard) it has theoretical reads of 355 MB/s and writes of 215 MB/s. While these writes were achieved in Gigabyte’s tests, this wasn’t the case for the reads that were much lower than announced. This is especially stange as the X58 motherboard used means the SATA 6 Gbps controller can connect directly to the chipset with PCI Express 2.0.





 CES: AMD 890FX from MSI
  Posted on 1263181474 by Damien

After the 890G from Asus, it's over to MSI with the AMD 890FX. This forthcoming high-end chipset should be available as of the spring and has been designed for the Phenom II hexacore and will have up to 4 PCI Express 8x ports to give Quad Crossfire X support, as is the case in the MSI implementation. The SB850 southbridge supports SATA 6 Gbps but not USB 3.0. For this, MSI has used the NEC controller for its 890FX-GD70.


Note that the manufacturer was also showing the 890GXM-GD65, a micro-ATX motherboard based on the AMD 890G.



 CES: MSI Radeon HD 5870 Lightning

MSI was showing a prototype of its customized Radeon HD 5870 that will take its place in the Lightning range. The manufacturer has decided to offer an alternative to the very long stock card PCB with a shorter but higher model. The Lightning will of course be overclocked but the clocks haven’t yet been fixed. It should arrive within a month at €30 more than the stock model.




 CES: AMD 890G
  Posted on 1263179365 by Damien

At CES at the ASUS stand, there was a sighting of the M4A89GTO PRO which is based on the RS890, the successor to the AMD 790GX. Unless there’s any change, it will be called the AMD 890G. It’s pretty much a higher end version of the 785G and in principle the same component clocked higher for the Direct X 10.1 IGP, that has a small dedicated memory.

What's more interesting is that the RS890 is linked to the SB800 southbridge that is the first to support SATA 6 Gbps natively. Asus has added a JMicron controller limited to SATA 3 Gbps that will also have an IDE connector. USB 3.0 is not supported either by the chipset or any other component, however, you’ll note a space designed for an additional component next to the connectors – we think this may be for an external USB 3.0 controller.

The M4A89GTO PRO should be with us in the second half of the year.
