cgvirus Posted February 24, 2016 Share Posted February 24, 2016 Hi folks, I need some suggestion. Should I purchase GDDR5 1GB or DDR3 2GB Readon R7 GPU card? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Atom Posted February 25, 2016 Share Posted February 25, 2016 Considering 2Gb is the minimum requirement to run Houdini, choose a 2Gb card or better. 1 Quote Link to comment Share on other sites More sharing options...

malexander Posted March 7, 2016 Share Posted March 7, 2016 Also, 2GB is the minimum if you're not running multiple monitors or very high-res monitors. Two QHD (2560x1440) or a 4K (UHD) monitor requires more VRAM (4GB or above is safe) simply due to the large framebuffer requirements for those setups - they eat VRAM for breakfast. If you run multiple Houdini sessions that the same time, you also might feel a bit constrained by 2GB. 1 Quote Link to comment Share on other sites More sharing options...
cgvirus Posted March 7, 2016 Author Share Posted March 7, 2016 I took the risk...Toms Hardware suggested 1 GB DDR5 will make the buffer size smoothly transported....And it's kind of true. I was comparing high scale ocean sim and 2GB was lower in the performance. Thankfully my store dealer was humble to make this happen. I have taken GDDR5 1 GB. Working smoothly with 8 million particles till now... Quote Link to comment Share on other sites More sharing options...
malexander Posted March 8, 2016 Share Posted March 8, 2016 DDR3 just has a lower bandwidth than GDDR5, but it's also more power efficient and less expensive, which is why a lot of the mid-to-low end cards feature DDR3. It also helps keep them within the 75W the PCI-Express slot provides to avoid external connectors, or in this case allows for twice the amount of memory in the same power envelope.
