64-bit performance increase
Hi David. I am going to upgrade my current Intensity capture station. I can capture 1080/60i at High quality with a stripped version of 32-bit XP with no dropouts. Memory is 800 MT/s DDR2 and CPU is 2.2 GHz Core 2 Duo w/ 4MB cache (Core 2 Duo T7200 overclocked to 2.2 GHz).
I am considering the Core 2 Duo SL9400 SLB65 1866 MHz 6 MB 1066 MT/s for the upgrade. I will run XP 64-bit, this has SSE 4.1 and 1066 MT/s memory support. With the memory there will be throughput increase of 25% (800 to 1066), not sure how much improvement SSE 4.1 gives. I have no idea how much of an improvement is given by 32-bit vs 64-bit in Cineform. Blackmagic does seem to have 64-bit XP drivers on its website so that should be fine.. Would appreciate your input, as this will improve my battery life by about 20%.(9W CPU improvement takes 50W to 41W as motherboard draw). |
The memory speed is where you get for most performance gain for CineForm encoding. Very little difference using 64-bit.

Sse 4.1
OK so there will 10-20% improvement with the improved memory speed. I don't think the Socket M Core 2 Duos had SSE 4.1
What is the improvement between the newer Penryn and the older Merom CPUs ?? I have to buy these to test it - so I am just trying to avoid an unnecessary hassle by asking you these questions.. |
I don't know the individual CPU models that well, there are just too many, so you might have to try. We don't do any particular SSE4.1 optimizition.

I think you're going to have issues with realtime CineForm capture at 1.8GHz regardless of the bus speed and memory throughput.

64-bit Vegas and Neo HD
Hi David. At this moment, can we use a 64-bit workflow with Vegas (any version ??) and Cineform 64-bit ?
Richard, I was able to capture with a 2 GHz CPU using Neo HD - I overclocked it to 2.2 GHz to be sure. This was about 800 MHz FSB and using Film Scan. With 1033 MHz FSB, there will be a performance increase and if I use High Quality. If I use the 17W TDP CPUs and overclock them to 2GHz - I think even Film Scan may be fine. 64-bit will still give more performance increase - just not sure how much. I will test and let everyone know. |
We have no 64-bit components yet.
