This is my first post in this amazing and long living thread. I write to recommend the new low profile Radeon HD7750 as an excellent replacement of the Nvidia7600GTL graphic card in the Vaio XL machines.
I have tested with the Sapphire version of the HD7750 card but I think other manufacturers cards will work as good, maybe better. I had in fact a bit problem with bad connection of the micro-HDMI connector which is awkwardly positioned in the top left corner of the Sapphire card. The VTX3D, Powercolor, HIS and Club3D cards have full size HDMI outputs which I would prefer. I don´t know if the other manufacturers card are as silent as the Sapphire though. The noise from the GPU fan of the Sapphire is negligible compared to the noise from the power supply fan except during heavy gaming.
The HD7750 fits right into my XL201 which I previously upgraded to 2 GB RAM and a E6600 2.4GHz Dual Core processor. The only artefact I noticed is that during startup the pictures of the Vaio and Intel logos are displaced 1/3 screenwidth to the right. It only occurs when HDMI is used and only before the Radeon driver kicks in. When the Radeon driver has started everything works perfectly with my Sharp TV, both HDMI sound, hibernation and wakeup.
Since I was concerned that the power consumption of the HD7750 could be too large for the 300W supply I measured and compared the total power of the Sony Vaio XL201 with the 7600GTL and the HD7750 respectively (see below). As seen the idle power in fact dropped 12W with the new card and there was only a 10W increase in the GPU-intensive tests. I also tested games that were both CPU and GPU intensive and the total power consumption with the HD7750 was always below 155W.
That's an interesting new video/graphics card. Thanks for making us aware of it. It looks like a good alternative choice for the various US and UK/European spec. VGX-XL* systems with Core2 Duo, 65 watt processors. which with a 64-bit OS are able to accept 8GB Max. RAM.
Your test results and the specs. do show it pulls quite a bit of juice while under load. I think those of us with Pentium D dual core, 95 watt processors (such as the US spec. VGX-XL1 and VGX-XL2 systems) -- which are already starting out at 30 watt and 4GB Max.RAM handicaps but using the very same 297 watt power supply -- would be better served with the Sapphire HD6670 HDMI Low Profile card which pulls less wattage under load, but also has 1GB of GDDR5 memory, system RAM sharing technology and similar performance specs:
A few of us are presently running this card in our systems with very good results. Especially Blu-ray playback stability and the graphics processing boost provided by system RAM sharing.
I look forward to reading feedback from anyone who may disagree with my assessment.
