Does Intel HD graphics boost dedicated graphics card performance?

[SP33Demon]

Most benchmarks only measure Intel's HD 3000 (or 4000) performance by itself. But what happens when you have a dedicated Graphics card such as Nvidia GTX 8xxx/9xxx? Will GTX performance be boosted by having on-chip Intel HD capability? Or do each (Intel HD and dedicated graphics card) run separately where Intel's HD would not affect the graphics card when both are in 1 system?

Intel's description of the technology didn't mention a boost to your graphics card but it would be interesting if it helped your card perform better.

For the uninformed in this thread who think that NVidia and Intel do not work together professionally:

"This agreement signals a new era for NVIDIA," said Jen-Hsun Huang, NVIDIA's president and chief executive officer. "Our cross license with Intel reflects the substantial value of our visual and parallel computing technologies. It also underscores the importance of our inventions to the future of personal computing, as well as the expanding markets for mobile and cloud computing."

Under the new agreement, Intel will have continued access to NVIDIA's full range of patents. In return, NVIDIA will receive an aggregate of $1.5 billion in licensing fees, to be paid in annual installments, and retain use of Intel's patents, consistent with its existing six-year agreement with Intel. This excludes Intel's proprietary processors, flash memory and certain chipsets for the Intel platform.

This would be in addition to Intel's HD improving benchmarking for encoding/decoding using Quicksync (which outperforms the latest greatest Nvidia/AMD GPU encoding times), so we know Intel is capable of doing it, i.e. optimizing the Intel HD for certain applications. What I'm wondering is if a 3rd party has already done this.

Nope it will not help, last I have seen. You can SLI/Crossfire 2 of the same cards but Intels will not help as far as I know.
Some have thought about trying to get the Intel to do the PhysX but I have not seen anyone get it to work.

Thanks for that info.

You'd think Intel would add SLI/Crossfire capability to its HD on-chip graphics if a user added an additional card; it'd be a huge selling point aside from the fact that it can run games without a dedicated card. Meh, it's Intel and they don't think of these things.

Nvidia and AMD's implementations are both covered by patents, and Intel isn't even in the market of discrete gaming cards. You do know that Nvidia isn't AMD isn't Intel, right? My guess would be "no," since you don't even know that there isn't an Nvidia 800 or 900 series.

I was wondering if any would recall this.. I use it and like it alot . There are those who say its dropping frames . As long as it doesn't show up on my screen I don't care about the nay sayers. It works and it adds alot of frames.

There's no point in "SLI'ing" or "Crossfiring" something as crappy as Intel HD 4000 with a gaming graphics card. Two completely different architectures, one of which has no dedicated VRAM. It doesn't work just like that, and to make it work would require a lot of planning and effort... and I honestly don't see the benefit of even going there. Intel's integrated graphics and other manufacturer's discrete graphics fill different niches.

Most the AMD NV guys will of course say will say Lucidlogix Virtu MVP doesn't do anything . If it shows in the benchmarks and removes tearing it works just fine . Its not SLi but it does help and every little bit to a true gamer adds up

Intresting, have not seen that before. Maybe have to see if it would get my HD4000 to help my GTX460.

Here's the list of mobos that have it:

Turns out my AsRock mini-ITX (haven't installed it yet) is on the list.

Sweetness, thanks Sable for that info. I'll definitely have to test it when I get my low profile graphics card.

Here are some gaming benchmarks (using the notebook from origin) Hyperformance mode means the hd 4000 is working in sync with the gt 650m.

You notice that for the most part it helps though only on lower settings (higher settings are the same or slightly slower-1 fps at most) on low resolution. Lucid logix seems to be better aimed at the mobile sector than desktops.

There are however massive gains in starcraft, going from 43 fps to over 100 at 1080p, gaining 2.5 times performance advantage.

Massive gain in skyrim at low resolutions, slight loss at 1080p

I think with some driver optimizations the hd 4000 (or the igpu in haswell) could really make a big difference. I could see the igpu being used for physics especially.
