"RS690" invades the notebook market

AMD yesterday announced its M690 mobile chipset family, formerly known as RS690M, for AMD Turion 64-based notebooks – M690V and M690T. The new mobile chipsets take the previously announced AMD 690G desktop chipset and pairs it with mobile-centric power saving features. AMD integrates the new power saving features into the ATI Radeon X1200 integrated graphics core.

New to the integrated ATI Radeon X1200 graphics core is a power-saving dynamic video memory allocation scheme. With the new scheme, system memory is automatically allocated to the graphics processor on the fly, at the GPU’s request. Intel implements a similar scheme in its graphics core since the fruition of the Intel Extreme Graphics core.

AMD has also integrated a new side-port memory feature in M690T chipsets, which allows notebook manufacturers to provide dedicated video memory to the ATI Radeon X1200 graphics core. AMD supports up to 128MB of video memory connected to the side-port bus.

The rest of the graphics core is identical to its desktop variant. AVIVO video processing features are available for enhanced video playback. The ATI Radeon X1200 graphics core features MPEG-2, MPEG-4 and WMV9 hardware accelerated video playback. There is also an integrated TV encoder for component, composite and S-Video outputs.

An integrated dual-link 24-bit LVDS interface provides connectivity to displays while a TMDS interface provides support for DVI and HDMI outputs. As with the desktop AMD 690G, the M690 features an integrated high-definition audio controller for HDMI audio functions. HDCP 1.1 content protection is also supported.

The AMD M690T chipset features additional output capabilities via internal DVO port. Manufacturers are able to add additional output capabilities using DVO compatible chips. However, a manufacturer can only take advantage of the DVO port or side-port memory, not both at the same time.

Other notable features of the chipset include one PCIe x16 interconnect for external graphics, four PCIe x1 links for other devices, 10 USB 2.0 ports, SATA 3.0 Gbps, ATA133, TPM 1.1 and 1.2, high-definition audio and PCI v2.3 support.

wonder how it compares (performance wise) to the X300 based graphics in the 200M series. Seems like some nice and long needed additions to the 200M series.

The inclusion of this new side port for adding dedicated video memory is going to be a good feature. With the notebook manufacturer adding a 128MB memory via this, we will be able to get a much higher performance than other integrated graphics solutions, although lower than that of a dedicated card.

What remains to be seen is by how much the cost will increase..

Actually it was said in a previous DT article that this memory is extremely low-bandwidth, and is just there to keep the IGP from waking up the CPU (since that's where the mem controller is) when it needs to access memory. So, fine for UMPCs, but don't expect to see it in a gaming laptop.

Just out of curiousity... since it shares a similar family name to the R600 (referring to the ATI X2x00 series), does this mean it supports DX 10?

In fact... does anyone by any chance know when we'll see DirectX 10 GPUs in laptops???

its an x700 derived core with added avivo features. so dx9 only

Intel's next IGP will be DX10 (and technically the current X3000 meets DX10 specs, but lacks a decent driver). One laptop at CEBIT had a mobile GeForce 8800. Don't worry, your mobile DX10 hardware needs will be met soon enough... all we need now are games.

The announcement was for availability, which I think means that as soon as the laptop manufacturers want it, they can get it. I think even with the slower AMD processors, this should still be faster for games than any other on-board laptop graphics. Of course, that probably means any games two years old will run fine, and most newer ones will be on low settings.

HP is already selling notebooks with X1200 graphics. Not sure if that's the same as the one above. I think so, since OEMs frequently get these products well before they are announced.

As for DX10 support, does it really matter? This is an IGP, mind you. A DX9 card will accelerate Vista just fine, and I highly doubt that a DX10 IGP using shared memory will be very useful running DX10 anything. However, it appears that this chipset will support any x16 PCIe graphics chip they make, so DX10 support can be supplied via an add-on card.

Other notable features of the chipset include one PCIe x16 interconnect for external graphics

Current external graphics solutions are hampered by meager PCI x1 interconnects. With full external x16 support a laptop could become a serious gaming machine with the addition of an external graphics enclosure like the XG Station. When it's time to go somewhere the integrated graphics will suffice, and batterly life will not suffer from the additional drain caused by the inclusion of an internal dedicated graphics solution. I, for one, am pretty excited about the possibilities.
