What does SSE2 stands for in case of GPU render (blenchmark)

Hi,

I just tried the new benchmark addon. And all works fine,
but my time result were very long in comparison to other users rendertime with similar GPUs.

I’m not a hardware maniac so my question is, what’s the difference:

GeForce GTX TITAN BLACK/PCIe/SSE2
rendertime: 24s

and

GeForce GTX TITAN BLACK
rendertime: 74s

The first one is three times faster, what does this SSE2 stands for?

IS that the same graphic card but CPU is somekind different, or motherboard?

How can I fix my card (or replace other things) to be as fast, or is it not possible?

My specs:

i7-2600K 3.40GHz
16GB RAM
Motherboard ASRock P67 Extreme6 (Sandy Bridge)
EVGA GeForce GTX TITAN BLACK Superclocked 6GB GDDR5
Win 7 64bit home premium

When i check GPU with CPU-Z program it says i have only 4GB VRAM :confused: don’t know why (GPU-Z states it’s all ok)

he could be using an optimized blender build from graphicall, it could be tile size, it could be a different os, he might have the memory adjusted for more memorey (windows puts a default cap on memory usage that can be changed). there are alot of variables. i remember way back int the day when i was running seti. i had to download sse2 software. some software does not take advantage of sse2 so thats why i am thinking it might be an optamised build from graphicall.

you best bet would be to ask the person that posted the benchmark. they could tell you for sure while i can only take wild guesses.

I used blenchmark.com so i was rendeing exactly the same as other users,
they have specified blender versions and OS, so it was also 2.72b with win7 64

Can’t write to those users cause all the benchamark is fully automated
and it shows only specs and rendertimes send by the benchmark scene after rendering.

I tried an optimized build (fastest CUDA something) and it was even slower for me…

The graphiccard should be ok, I used gtx570 before and after switching to titan rendering got much much faster,
exactly as I predicted it to be.

But compared to other users times it’s still really slow :confused:

I thought that maybe its motherborad fault.

It has PCIe 2.0 slots and TITan can use 3.0 version, but it doesn’t matter for the rendering process,
only for sending the data, and building up the scene before rendering takes 6 seconds,

so even if it was 1 sec for 3.0 slot I’m still missing almost one minute :frowning:

Hi, if you look at the benchmarks-overview page there must be something wrong.
A GT 430 is faster than a GTX 760. ?
Blender 2.72b is faster than 2.70 on GTX 780Ti !
SSE2 is a CPU extension, has nothing to do with GPU and comes 2001.

Cheers, mib

why there is SSE2 in here then?

Hi, 9 years later, wow.
To be honest I have no idea
Either the Nvidia driver need at least a SSE2 CPU or a PCIe 2.0 bus.
A quick search gives not really suitable results.
It seems nobody else knew this at this time either. :slight_smile:
