Conroe and video encoding

[Adnan769]

Hi all,
I was wondering if Conroe will be good at video encoding as the Pentium 4's & D's. I was wondering if Intel comprimized video editing speed by improving its speed in other applications..

If someone knows or can pridect by Conroe structure then please tell us what to expect.

Thanks in advance

It is substantially faster than the P4 and thrashes the A64 at encoding. They did a lot of work optimising the SSE (versions 2, 3 and 4) instructions and the Conroe actually has no less than 3 vector logic units (which are used by the SSE instructions and particularly video encoding extensively...) 2 of which can run in parallel. The P4 and A64 only have 1.

Also the datapaths to conroe's SSE units are 128bit wide in conroe. P4's and AMD's have to break the 128bit SSE instructions down into 2x64bit chunks, process them, and then reconsitute the 128bit result. Conroe's 128bit internals can do it in a single instruction.

Reducing SSE instructions from 2 parts to 1, also reduces 'space' each SSE instruction takes in the pipeline, allowing the processor to 'flow' better.

Thats good to hear.

Thanks for the info NathanE, Corasik
