Preliminary testing sees a single NVDEC job on a 128Bit GTX 1050 Ti 4GB (Pascal) unable to use more than 30% (112 FPS) of the NVDEC. *VDPAU nVidia PureVideo Information VRAM Bandwidth *NVENC FPS based on Single Pass quality profile. > benoit.zuber at ana.unibe.*h.264 FPS Based on YUV 4:2:0 8-bit. > Another question: has anyone done benchmark comparison for 3D rendering in Chimera between a top of the line Geforce GTX card and a top Quadro card?

We have 3 Geforce GTX 780 Ti (mainly used for number crunching) on a particular workstation and would be interested to make full use of them for rendering tomograms or serial block face imaging data. Here are Chimera benchmarks for a range of graphics cards: In general I think the Geforce cards perform better (fewer bugs, faster speed) than the Quadro cards, and would only recommend Quadro if you use stereoscopic display with shutter glasses. If you explain exactly the case where you see slow rendering I can perhaps advise. When you first load a big map it can take a long time because disk drive speed is slow - a solid state drive helps speed this up. This all relates to the speed rotating the model. If the data does fit on the graphics card, it usually renders at full frame rate (60 frames per second), although that isn’t true of all graphics cards.

I think slow rendering of maps in solid (grayscale) style typically happens in Chimera when the map data doesn’t fit on the graphics card, so every frame it has to transfer all the data to the card - the performance plummets once you get a map that big. I have my doubts that this will improve Chimera rendering speed for large density maps. From what I understand they do thing like have each of 2 cards render every other frame - since the graphics are pipelined the current frame and next frame could be rendered simultaneously possibly doubling the speed. With Nvidia cards this technology is called SLI and with AMD cards it is called CrossFire. I don’t think applications need any special support to use multiple cards - the system graphics driver distributes the work across 2 or more cards. I don’t know if it is likely to improve rendering speed. I haven’t tried Chimera with 2 or more graphics cards working together. Multi GPU rendering Tom Goddard goddard at
