I have been reading up for a new gaming comp I want to build. I read the article here, "Core i5-3570K, -3550, -3550S, And -3570T: Ivy Bridge Efficiency ". What does the Intel HD graphics 2500 and 4000 mean on these cpus??? Is that built in graphics or what???
 


Yup, built in graphics. I'm using Intel HD Graphics 1000, and can do anything except for 3D gaming.
 
Ok so its integrated graphics. Then my next question would be why??? What does integrated graphics do for you when your going to use a graphics card anyway?? I have used AMD CPU's in the past, so integrated graphics is a new concept to me.

Right now I'm looking at a new high speed computer build, and my most important two choices of course are CPU and Graphics card. My choice so far is , CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155 77W Quad-Core Desktop Processor Intel HD Graphics 4000, and Graphics card: EVGA 02G-P4-2670-KR GeForce GTX 670 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card. The rest of the build is in progress , and not certain yet.
 
it is for non gaming peoplr AKA your mom lol. Just want to e-mail surf the web and play facebook games and in that case even the 1000 is fine... Not for enthusiast at all.. although I think it does play apart in the new transcoding Intel touts as a feature.

Thent
 

AMD is moving towards putting IGPs in all their CPUs as well. Half their current CPUs are branded "APUs" which are hybrid CPU+GPU.

Intel's QuickSync uses the IGP for video decoding/encoding and on HD4000, QuickSync transcode is 2-3X faster than the next fastest thing available on PC including GPU acceleration.

There is also a possibility that IGPs can be used for heterogeneous computing, which is more or less what VirtuMVP does: use the IGP to pre-process 3D scenes before sending them to the GPU for rendering in order to reduce the amount of over-drawing.
 
Intel HD is still nowhere near being taken seriously, it is fine for a office machine or basic home pc for the mum but beyond that, it is a bag of nuts. Compared to Llano it is hopelessly irrelevent, considering Llano is a year old and trinity is due it will again be made to look like a bag of nuts. Any kind of gaming would be better served on a dedicated graphics card as Intels IGP is rather non-existent.

(PS: Ran the F1 2011 benchmark at 16:9 and it barely made it past 10 FPS which is unplayable, on low settings it tops out at around 27 FPS)
 

Graphics is only one of many roles the IGP can potentially play. For people who frequently transcode DVD/BD movies for iPad/iPhone/whatever, QuickSync on HD4000 is several times faster than software and GPGPU transcode while providing better quality. If games start leveraging OpenCL or other forms of heterogeneous computing such as running game physics on IGP instead of robbing bandwidth off the GPU with GPGPU or burning CPU cycles for improved response times and better power efficiency.

Graphics is only the tip of the iceberg, the obvious application. Things will get more exciting for IGPs combined with discrete GPU(s) if/when heterogeneous computing becomes more common.
 


I don't deny that it has a versitile role, but apart from transcoding which is also software assisted Intels solution is rather archiac, when it comes to heterogeneous computing the AMD solutions are still ahead.
