I have added Photoscan to AnandTech's results database.
I just added the results from about a dozen CPUs that were not in the database, and I have a fair number lined up over the coming months.

Link for all results: http://www.anandtech.com/bench/CPU/1057

I have two sets of E5 processors which I will test after Computex in June.

I should have a new update to my CPU tests in the next couple of weeks.

If anyone is interested, here are my stage settings for the benchmark:

Code: [Select]

## parameters used:
## Align Photos: High, disabled, 40000
## Build Dense Cloud: Medium, Aggressive
## Build Model: Arbitrary, Dense, Interpolation=Enabled, Medium
## Build Texture: Generic, Mosaic, 4096, 1

It's the Building Reconstruction set on http://www.agisoft.ru/tutorials/photoscan/

Some more results, including with 12/8 core Xeons:

Latest update to these results.

Click the link to see breakdown:
http://anandtech.com/show/7752/msi-x79agd45-plus-review-building-up/7



I'm currently sitting here with a 12 core Xeon with 24 threads, 32GB DRAM 1600 C11, and it doesn't seem to be any faster than a 4960X.  This is because the single threaded speed of the Xeon is poor, and despite having 2x threads, is down 25% in MHz for the multithreaded stuff.  I will add these results on my Xeon article, coming soon (hopefully).

Based on my memory testing of Ivy Bridge and Haswell consumer platforms, there are simple rules when it comes to memory (if money is no object).

1. Calculate the Performance Index (PI).  PI = MHz / CAS Latency
2. Choose the one with the higher PI.
3. If your options have similar PI, choose the one with the higher MHz.

Sources:
Haswell Memory Scaling: http://www.anandtech.com/show/7364/memory-scaling-on-haswell
Ivy Bridge Memory Scaling: http://www.anandtech.com/show/6372/

Here's a general graph on a memory intensive benchmark (Dirt3), FPS vs PI:



When I get around to doing a memory scaling article on a few upcoming platforms and scenarios, I will have data to back it up.  I should have access to a dual socket motherboard within the next few months, and some high end CPUs (either 8, 10 or 12 cores) to do some other testing for you, but please bear with me

Our benchmark uses the 50 image building tutorial set from here: http://www.agisoft.ru/tutorials/photoscan/02/

We use the following settings:

## Align Photos: High, disabled, 40000
## Build Dense Cloud: Medium, Aggressive
## Build Model: Arbitrary, Dense, Interpolation=Enabled, Medium
## Build Texture: Generic, Mosaic, 4096, 1

By recommendation from Agisoft, the GPU numbers have two CPU cores disabled each.  Meaning that Stage 1/3/4, which do not use the GPU, might look slower than when the GPU is not used.

The test takes between 15 minutes (6-core Ivy Bridge-E) and an hour (Haswell mobile CPU) usually.

Basically we have to balance benchmark time - we can't have something that runs for a day.  Wouldn't get paid otherwise!  Especially as my normal benchmark routine takes 20-30 hours to get through (we are a computer component review website).

Even if you feel you cannot take the results quantitatively, take them qualitatively - it at least shows X > Y.

I might get a chance to try the Mac Pro next week.  The boss just reviewed one, but I have to get him to give me remote access to test.  The 1866 C13 memory is going to kill performance though.  ECC JEDEC standards are pretty lax, which makes me wonder if you can put normal non-ECC memory in it for a bit of a boost (and the system will enable XMP too).

First set of results with the GIGABYTE BRIX Pro:

http://www.anandtech.com/show/7648/gigabyte-brix-pro/3

It seems:

Stage 1 prefers cores and MHz
Stage 2 needs fast memory / GPUs
Stage 3 likes high IPC and memory
Stage 4 likes cores and MHz

This was only a first set of quick results put together for a preview.  Will hopefully have more by the end of the month on more platforms / DRAM combinations.
