Performance with AMD Turion 64 2GHz

Tatsh · 20th June 2006, 14:17

HP has begun making AMD Turion 64 laptops and I bought one. The CPU downclocks when doing things like internet browsing to 800MHz (200 x 4), video decoding at 1.6GHz (200 x 8), and video encoding at 2GHz (200 x 10). I do not know how it knows what needs full speed or partial speed or the slowest available speed, but somehow VirtualDub has it going up to 2GHz.

When I run DGIndex with 32-bit SSE2 MMX, the speed of the processor is 1.6GHz, which is of course much better than 800MHz. It takes about 5 minutes (I don't know if this is usual) per each 20 minutes or so (tv episodes).

Does anyone know a trick to make the processor stay at 2GHz or make a program tell the processor to stay at 2GHz? The processor even has its own drivers from HP, but even before the drivers it was re-multiplying all the time. VirtualDub somehow has the processor believing that it needs the full 2GHz. I'd love if DGIndex could do that too.

I think when creating a project with dgindex, you're limited by the hard disk transfer speed rather than your cpu. I always make sure to try and save the project file to a different physical drive than where the original vob/m2v/tp files are stored.

I'm sort of beginning to think that. The difference in HD speed, such as the RPM being 4200 instead of 7200, or otherwise it's the SATA -> USB2 adaptor speed, which is significantly slower than actual SATA.

The easy way to check: hit ctrl-alt-del, go to the processes tab and check how much cpu dgindex is using while it is creating the project. Unless it's close to 100%, your cpu isn't the bottleneck. Mine sits at around 16%.

Hi,

Try RightMark CPU clock utility (RMclock HLT), it has different settings so you can switch from power saving to maximal performance to performance on demand

I agree on DG Index and have tried full power with little to no gain.

Thanks. I'll definitely try that.

EDIT: That works great, but does not affect DGIndex so it is definitely the HD speed now.
