So I have just recently bought the AMD professional series GPU..the Firepro W8100.
The performance in Autodesk 3ds max and Vray is meh.
I rendered a simple scene with my old XFX Radeon 6870 2GB and then again on my brand new Firepro W8100 using the Vray 3.00.0.7 rendering engine and I got the same crap performance. I was also monitoring gpu activity during the render which came back with a essentially zero gpu activity 😞
wondering if it could be caused by my MB (ASUS Crosshair v Formula-Z) which only has up to x16 PCIE 2.0 slots...not 3.0 which my new graphics card can run up to.
amd does say this about the card: "Available PCIE x16 (dual-slot), 3.0 for optimal performance"...how much better performance is the question?
Could the gpu drivers be optimized for PCIE 3.0 of such a thing exists?
PCIe Raw bit rate Interconnect bandwidth Bandwidth per lane per direction Total bandwidth for x16 link
PCIe 1.x 2.5GT/s 2Gbps ~250MB/s ~8GB/s
PCIe 2.x 5.0GT/s 4Gbps ~500MB/s ~16GB/s
PCIe 3.0 8.0GT/s 8Gbps ~1GB/s ~32GB/s
so...i am still confused by this data above.
I have read that PCIE 2.0 is more than enough for modern gpu's but benchmarking doesnt usually include workstation graphic cards that support this argument.
Here is my computer specs:
MB: ASUS Crosshiar V Formula-Z
CPU: AMD FX 8350 (8-Core) @ 4.7Ghz
RAM: Corsair Dominator Platinum - 16GB (tested with windows ram test and ramx86 program too--no errors reported)
GPU: XFX Radeon HD 6870 2GB
PSU: NZXT Hale90 v.2 1200watts (bought recently)
custom water cooled CPU/northbrdige loop
here is the GPU specs...
AMD Firepro W8100 GPU:
SPECS

what does all this mean?
