AMD Card

How fast will Iray render or should it render with CPU only AMD Radeon card? I am new to this but not sure of the settings and such for rendering a single character with lights. I had one that started late at night and rendered through the night when I woke up it was still rendering so it was almost a whole day and half the night and was only at 98% at 4:00 pm that next day. So I stopped it and saved the character because it looked really good but I can't have them to render for days lol. What am I doing wrong? What are good settings?

Iray needs an Nvidea Card with CUDA cores. With an AMD card, it defaults to CPU rendering.
Render times depend then on your CPU speed, but also on things like "how many lights are used, is there a lot light or only a little, what materials are you trying to render", etc.
The 98% completion is an artificial value, by the way. If the image looks good to you, then you can cancel it before. However, if you used the default render settings, then it should have stopped rendering after 2 hours. Did you change the render settings from default to something different?
I am not at home right now but as soon as I get there I will put up the specs. I am pretty sure it is 8 gigabytes of RAM. I did change the settings to 0 so that's why it went so long but after the default setting it still looked grainy and noisy not smooth at all and like it was unfinished. Thats why I changed the setting to 0. There were I think 4 lights. I'm pretty sure this is the computer we have but I will check when I get home. Should I use Lux instead of Iray?

Lux can use an AMD card to accelerate rendering but the card in that system is a very baseline card and I would not ask too much of it. Your CPU is also a core 2 system designed for laptops and from what I'm reading it's a stretch to call it dual core because of how it was designed. LuxRender can be a significantly CPU intensive affair even for workstation class computers, which your system is not in that ballpark, and Iray is going to suffer a similar fate on that computer unless you are okay with letting either one of those render engines run for many hours or possibly days for a single project, even then I'd keep the output size as small as possible. On the other hand 3Delight is still a very viable solution due to the limitations of that CPU and GPU combo because you have a decent amount of RAM and the necessary CPU calculations can be far less demanding than what's needed with Lux or Iray.
One big advantage that Luxrender has...easy set up of network rendering/render nodes...and basically any computer that can run Luxrender and has enough memory can be set up to become a node.
Ok here is what my system file says.
You don't have an AMD card, but rather an integrated GPU on your AMD CPU, which AMD calls an APU. You can render in IRAY with CPU only, though I'm not sure how IRAY will treat the GPU cores on your processor. Either way, you should expect it to be slow.
Ok thanks so much for all the help.
Is there anything I can render with that will be faster? What is the OpenCl with reality I see it on my setting is that any good?
Luxrender with GPU acceleration is faster...but how much with an integrated GPU, I don't know. Unlike a dedicated video card, it's still sharing system resources, like memory.
I took a look at your specs this is a AMD APU processor. This means your video is built into the cpu. The good news is you can use onboard video to run your monitors and buy a Nvidia 750ti with 4gb of video ram and 640 cuda cores or you can buy a Nvidia Tesla M2090 with 512 cuda cores and 6gb of video ram.
Both options can be had under $150 dollars. If you can afford it I would recommend a Nvidia 980 6gb video ram and 2800 cuda cores but this will run you about $600 on sale.
Thank you so much I am wandering what kind of computer I have it doesn't seem very good my son wanted it for a gaming computer so I thought it would be a good one but not so sure now. Thanks so much I was just wandering about the Nvidia cards and if they would work in my computer. I am deffinately going to see what I can do.
