The ultimate GPU upgrade decision…So I’ve been waiting for these cards to upgrade my GTX 660 Ti for a long time, it’s finally here. From GPU rendering engine perspective, GTX 1080 seems to be a better deal than 1070. The 1080 has a lot more CUDAs than 1070, so 1080 is a better deal based on cost per CUDA.
Just my two cents here, but I read that the 1080 has memory twice as fast as the 1070, so I suppose that the 1080 is much faster, maybe even twice as fast as the 1070, but not twice as expensive, if that is the case, it seems to me the 1080 is the logical choice for rendering!
The first question to have ask here is: Does the 1080 is faster than a 980TI and how many percent of render time compare to percent of price. Today, no one knows how fast is a 1080
Hi, this Blenchmark is not really helpful although it was a lot of work to create it.
For example a single GTX TitanX need 55 seconds but four TitanX need 24 seconds. ?
Nobody knows wich Blender Version was used, GTX 10xx need Cuda 8, how fast is a GTX 980Ti with Cuda 8.
And so forth.
We really need a benchmark application from Blender.org like Luxmark, Octanebench, Arionbench, Benchwell (Maxwell), and so forth.
Completely agree.
These blenchmark results are confusing and contradictory. We need something like Luxmark, with heavy different scenes including slow materials, and not simple scenes such as the BMW. It is also important that the application certifying the results, avoiding possible cheating. For example with nvidia/amd fanboys.
The CUDA 8 SDK/runtime supports older architectures as well. Conversely, older CUDA SDKs don’t support building for Pascal.
However, not all features introduced in CUDA 8 will be available on older architectures. For instance, Unified Memory with system RAM fallback only works on Pascal.
I went with GTX 1070 last year when i upgraded by its an SLi motherboard and 800watt PSU so i have the option of putting a 2nd GPU in. You may want to look at what used GPUs flood the market after the cryptocurrency meltdown, or which ones Nvidia has too many of. My guess is there will be more 1070s they need to get rid off than 1080s, meaning beder prices.
I use 1070 along with Ryzen 8 core in blender and both together make for very fast renders, so fast that you wont be worrying about paying a little more to knock a few mins of the render time.
Sounds like a utilization of the GPU issue, maybe tile size for the render. Or it could be that some of the systems are making use of the CPU +GPU hybrid render, and the 1080s for some reason using GPU only.
To clear up confusion, in my version of 2.79 i select GPU render, in order to use the hybrid +CPU+GPU rendering. I select CPU render to use just CPU.
