When processors have built in GPU's, do they work together with discrete video??

Just wondering if when a processor like Llano or i5 2500k have a discrete card on the system it's running, if the built in GPU on the processor works with the discrete card, or if it is shut off. Thanks!

And on that note, Llano AMD A8-3850 or i5 2500k for a mostly gaming rig??

You question about on and off of onboard video can and does vary with the motherboard in use. Most will run with discrete video only. Whether or not the onboard will also work at the same time as the discrete card is the part that can be board dependent.

(And on that note, Llano AMD A8-3850 or i5 2500k for a mostly gaming rig??) = That is probably a real tossup. If you do anything other than game, like video rendering/editting, then the i5 2500k would be the best when using a discrete video card.
 
You gotta ask, there's no real pattern. With the AMD APUs on the FM1 socket, you can "Hybrid Crossfire" with any GPU up to a 6670.
 
The reason I answered his question in the way that I did was because most of these guys game. Gaming on the IGPU on i5 2500K is not going to be as good as the Llano with IGP. But I don't think you can do all the synced editting that you speak of with the discrete card working. But remove or disable the discrete for heavy duty editting then the i5 2500k is balls to the wall fast as the IGP does processing as well.

It will depend on what the OP really had in mind. Not much reason to ask about discrete if you do not plan to use it. Well I don't guess there is. He really asked a completely variable question like so many do and then the answer is hugely variable as well.

Well, I was debating on building an HTPC/mid gaming rig, and I was looking into the Llano because I found some benchmarks that were comparing it to the i5 2500k, which I was going to use for my main build, and the benchmarks for the Llano on low level gaming crushed the i5, so I figured I would as about it for both rigs since I haven't really looked into the Llano much at all.

Sounds like Llano w/ a 6670 would be the way to go for the HTPC at least.
 
Yeah, if you're talking about iGPU performance, the Llano+6670 will beat the 2500K's iGPU. But in terms of straight CPU performance, the 2500K beats the Llano hands down.
 
Yeah, I don't want to spend too much on the HTPC, looks like that would be a good way to go about it. No need for an 2500k for something like that I don't think.

On a Z68 with Lucid you can spank the Llano, get QuickSync and jump to IGP only to save power/reduce heat.

Could you show me the benches where the IGP on the Llano whips the i5?

In Xfire yeah it wins: http://www.anandtech.com/show/4476/amd-a83850-review/6

But against a 6770 http://www.rage3d.com/reviews/video/sapphire_hd6670_ultimate/index.php?p=4

Now unless I am missing something you can get a 6750 or 6770 for 20-40 more, drop it on an i5 and spank (well beat I havent seen i5 vsLlano gaming benched with the 6770)the Llano in X-fire in all video benches and still have the more compute power and the hybrid IGP usage for when you are not gaming.

I did mention at lower gaming levels it took out the i5. Here is what I was referring to. Thank you for yours though as that also factors in to my decision, but again I'm not looking to spend a lot on this HTPC. Here is the link: http://www.bjorn3d.com/read.php?cID=2079&pageID=10740

This is a machine mainly for watching media, light web surfing, music, and some average gameplay if I don't feel like playing in front of a PC at my desk.

If your really looking to go lite on an htpc/light gamer type build you don't even need a 6670. I am in the process of doing my wifes fusion build using an A8-3850 with 6670 but I had to RMA the video card so were running just the IGP right now. It will play the games we spend our time on(LoL, SC2, and a few other MMOs) at 720p on high detail ~40fps in SC2 and ~80fps in LoL.

I dont know if the IGP on the intel chips can be used in a combination configuration. I doubt that you could xfire or SLI it with a discrete GPU but I imagine that you should be able to use it for a 2nd monitor(out of game) or for its other supported compute operations while using a discrete card.
 
Llanos IGP is a lot more capable than Intels. Good enough for light gaming on its on. If you add a 65xx/66xx discrete GPU to the system it will hybrid crossfire.
 
Knufire had actually mentioned that in an earlier comment. Yeah, that seems like the way to go if one wants to build an inexpensive HTPC w/ decent gaming capabilities! :)

I actually just threw together a nice little HTPC machine on Newegg quick with this configuration and it came in @ $560 shipped. Used DVD-RW for now, and I just threw in the cheapest HDD I could find for $50 since the flood/shortage, but I would be building this when prices are back to normal so I assume that that's about what I would be paying for a drive. I'm thinking about doing this one sometime around December/January.

HDD(Price Filler til Prices Drop. Would be looking at a 1TB drive): http://www.newegg.com/Product/Product.aspx?Item=N82E16822136195

Fun. :)

The PSU and video card won't fit in that case, it's a slim form factor. I'd go with something like this, comes it at $600 shipped but you pay a slight premium for miniITX:
