Sigma Photo Pro (SPP) 6.5.0 Performance Review
25th December, 2016
Sigma recently released Sigma Photo Pro 6.5.0, which brings many new features and an improved performance, specially for Sigma dp and SD Quattro raw files. Here are the release notes for the SPP 6.5.0:
* It is compatible with RAW data (X3F files, X3I files) of the sd Quattro H.
* It increases the processing speed of RAW data in the Review Window and when it saves images, by utilizing the GPU (Graphics Processing Unit) (RAW data of sd Quattro series and dp Quattro series only).
* It is compatible with thumbnails and shooting information of DNG files shot with the sd Quattro H (If the files are edited using other processing software compatible with DNG files, they will not be displayed).
* It has an improved algorithm in Super Fine Detail Mode so that minor gaps between each frame are less visible.
* It has an improved algorithm in noise reduction when developing RAW data for the sd Quattro series and dp Quattro series.
* It has an updated Auto development algorithm of RAW data adjustment setting for the sd Quattro series and dp Quattro series.
* It corrects the phenomenon whereby the parameter of Auto development is different when Display Quality or Display Speed is prioritized.
* Preference Settings incorporates a mode whereby images transferred from Sigma Capture Pro will not open in the Review Window.
* It incorporates an Update Information Notification function. It displays messages for some functions by way of a pop-up notification.
My test method was very simple. I chose five raw files from my hard drive for dp1 Merrill and dp2 Quattro camera and downloaded four raw files of Sigma SD Quattro H for the test (Thanks goes to Wesley Wong for the raw files). Please check out his blog page here: http://giclee-art.my//
I simply exported the files in JPEG and S-HI JPEG where available (Merrill does not support S-HI export option)
Aorus X3 Plus V5
CPU: Intel i7-6700HQ 2.60GHz (Turbo goes up to 3.20GHz)
RAM: 32GB DDR4 2133MHz
SSD: Samsung SM951 512GB M.2 SSD
GPU: NVIDIA GeForce GTX 970M (Dedicated) and Intel HD Graphics 530 (Built-in)
OS: Windows 10 Pro
Software: SPP 6.5.0 installed (Extra memory allocation for acceleration was ON and GPU Support turned ON and OFF as needed)
Sigma SD Quattro H
Standard JPEG - 1:38 / S-HI JPEG - 1:58 - No GPU
Standard JPEG - 1:08 / S-HI JPEG - 1:28 - GPU Support (NVIDIA GeForce GTX 970M)
Sigma dp2 Quattro
Standard JPEG - 1:36 / S-HI JPEG - 2:01 - No GPU
Standard JPEG - 1:12 / S-HI JPEG - 1:36 - GPU Support (Intel HD Graphics 530)
Standard JPEG - 1:07 / S-HI JPEG - 1:31 - GPU Support (NVIDIA GeForce GTX 970M)
Sigma dp1 Merrill
Standard JPEG - 1:01 - No GPU
Standard JPEG - 1:03 - GPU Support (NVIDIA GeForce GTX 970M)
The results gives us the following:
* GPU Support does bring performance improvement, specially for the dp Quattro and SD Quattro series camera raw files.
* A quick test of two different GPU showed that although GPU acceleration is supported, it is not refined. There is a very little difference between the two GPUs considering the horse power and feature difference between NVIDIA GeForce GTX 970M and Intel HD Graphics 530.
* GPU support actually increased the export time of dp1 Merrill files, so it is clear that there is no support for Merrill files at this moment. I hope Sigma will add this later, as there are a lot of Merrill camera users out there, including me.
