As with the Energy viewset, which covered geophysical surveys and imaging, SPECviewperf 12 uses a synthetic suite to represent the medical field, making use of functionality that is often used for this kind of texture-based volume rendering. Two-dimensional images, created through the use of computer tomography (CT) or magnetic resonance imaging (MRI), are combined into a 3D representation.
The direct volume rendering is achieved by lining up the image slices in parallel. This is done based on texture coordinates, which are specified at every single vertex. They consist of the location in the 3D space (x, y, and z) and also define the alignment and scaling of the texture on the polygon via an object. Next, the values needed for the actual display are calculated based on the texture coordinates. This is called compositing. The entire volume can be thought of as a large number of voxels, or volume pixels, which contain opacity and color on top of the texture information.
Volume ray casting is used to calculate the actual image from the voxels. The present benchmark has two parts. The “4D Heart Data Set” contains several 3D objects, and the “Stag Beetle” places large demands on memory.
Weighting for the 10 individual tests is found in a handy table below. Not surprisingly, AMD's FirePro W7000 serves as our example again.

- SPECviewperf 12: A Much-Needed And Welcome Update










When AMD releases the mighty 16GB FirePro 9100 based on Radeon R9-290X core will be competitive to the Quadro K6000 in performance.
I find that internal benchmarking the only way to really understand the value of workstation cards. W7000 for example - it was awesome in our internal testing. While good, the cards is much better than these benchmark results suggest. Not sure why I would look at another SPEC benchmark when I will still need to test the cards in-house to really know how good they are for our applications and models.
Unfortunately, testing in the real applications (using something like APCapc) requires actual licenses of the software apps. Many of these vendors (CATIA, NX, etc) simply don't make temp licenses available for reviewers/journalists or other non-users.
VP12 should be quite good enough to help make informed evaluations of GPU hardware. If you are concerned about seeing in-application performance measurements for particular apps, you can ususually find the data with a bit of googling, although take results you find posted on the internet by "regular Joe's" with a grain of salt.

About CPU Scaling: "In the second set of our scaling results, only SolidWorks responds to CPU frequency. Core and thread count don't make a difference.¨
This is not entirely true. It goes as far as 10% at 4.5 GHz.

It is so problematic to read the posts above too? I wrote:
And for your information: AMD (Sapphire included) was not able to send me a R9 295X2 to my lab here in Germany! So I had to wait for Chris' card (yes, we've paid 550 bucks only for FedEx Priority from U.S. to Germany) and I was so lucky to handle two launch articles at the same time. The day has 24 hrs only, sorry for my laziness.
You get the complete W9100 story (the updated SPECviewperf12 is only a part of this) on 17 pages, don't worry, but it must be translated first.
Titan is good for compute, the SPECviewperf12 is more graphics related. No chance for consumer cards.
"Don't bother with anything else because Nvidia K6000 is the fastest."
You see the results of the consumer cards inside? The Titan is a little bit slower than the tested GTX 780 Ti, the Titan Black is in such cases 2-3% faster. But both are slower than a 780 Ti OC and the results of this card are in the most cases absolutelly worthles. I've tested the consumer cards belong the workstion graphics only for demonstration purposes.
But it really makes no sense to run pro-apps with non-certified hardware and drivers!
A better question is this. The 780 TI OC is faster than a titan black? And are these tests with the normal 780 TI driver? If so for working not he road a 780 ti rig will do the job.
