Interesting thought 460m vs. 6970m

We all know that with the 460M, the intel integrated GPU is disabled, while with the 6970M or the 6870M it's not.

It turns out that has bigger ramifications than just battery life! Read this article on tomshardware.com, and you learn about the QuickSync feature, which is hardware acceleration specifically for video encoding and playback, which is built into the Sandy Bridge GPU, but is only available while the GPU is turned on! In other words, the 6970M and 6870M based m17x's will be faster at transcoding and playing back video with the AMD GPU turned OFF than the 460M based m17x's! And it's a LOT faster too! In the tests they did, the Sandy Bridge GPU was about 5x faster than the NVidia Geforce GTX 560.

Sandy Bridge?s Secret Weapon: Quick Sync : Intel?s Second-Gen Core CPUs: The Sandy Bridge Review

 

The IGP of the Sandy Bridge is available to all GTX 460M models WITHOUT 120 Hz screen.

And yes Quick sync is faster in certain applications, while the IGP is getting raped by discrete GPUs in many other

 

Interesting, I thought I'd read that the IGP disabling had something fundamentally to do with the NVidia card. Is it just not able to drive the 120hz display?

Obviously the IGP is going to get beaten like a red-headed stepchild by a discrete GPU in graphics. I didn't realize there was a connection, though, to video encoding which made it a more compelling option, even if the encoding software supports CUDA.

 

it was reported that turning off 3D on the 120hz systems allowed the use of intel graphics

 

Not possible. With the 3d bundle, the igp doesn't even show up. It's completely bypassed. No switching, no change in bios. Screen it tied directly to nvidia card despite what Dell sales pope say.

 

prob no drivers installed for the intel GPU

 

Geoff....you miss the point.....on Nvidia systems, you cant even see the intel card in the BOIS....its is not available...it is not a driver issue.

 

I wonder why Dell decided to tie the display directly to the GPU on the 460 models.

For that matter, I wonder why that display isn't available with the 6970. HP uses a 6870 to drive a 120hz display in the Envy 17 3D, so it's not a GPU limitation, unless this particular display isn't compatible with AMD HD3D.

 

dell did not decide this, nor did nvidia. the intel igp does not support 120Hz.

Ah, got it.

In any case, that simply confirms my original thought. The 6970 based m17x configurations will be faster at video encoding/playback than the NVidia based ones.

Edit: Vikingrinn pointed out that someone might buy the 460m WITHOUT the 120hz display, in which case it wouldn't have the Intel GPU disabled. He's right, of course!

yes, the M17x R3 60Hz machines (which btw include both nvidia and amd discrete gpu's...) will benefit in some coding instances by use of the intel igp, aside from improved battery life.

 

it really really bothers me that wireless HD through the intel 6300 will not work on 3D machines, that is a huge failing and shortfall, it also highlights an issue when ordering a machine through a 3rd party

 

WirelessHD works on all laptops, even 3D machines. Intel 6300 got nothing to do with the technology. All you need is a transmitter and a reciever

 

Don't confuse widi or wireless display with wireless hd streaming.

For widi, you need the intel graphics chip, a compatiable intel I series processor and reciever like netgear's push 2 tv. Intel widi google search should get you to intel or to net gear.

For wireless hd streaming you need the chip in the r3 ( still don't know if current ones have it yet ) and a wireless hd reciever. Some tvs are being or already currently developed with the reciever built in. See the wireless hd site for more info.

Widi cant handle intense things like video games, and full 1080 movies without th occasional lag, so a wireless hd consortium was formed as a different format, some say to get into the intel stranglehold on the technology.

 

The first version of WiDi only supported 720p and you had to watch the same one both the laptop screen and the TV at the same time. But with WiDi 2.0 you can stream 1080p and do whatever you want with the laptop while streaming movies etc on the TV.
I know that WiDi 1.0 had less than a second lag which meant you would suffer if you were gaming on the big flatscreen but for movies it doesn`t matter if you have lag between the laptop screen and the TV.
They have improved the lag a lot with WiDi 2.0, now down to few miliseconds from what i have read

 

SO does that mean that all m17x r3 s have a wireless HD transmitter builtin??

 

It looks like it is a possibility.

It sounds like the WiDi transmitter is a part of the Intel wireless card ...

 

BUHUUUUUUU i am literally crying here. I have tried 1000 times to tell you guys that WiDi and WiHD (WirelessHD) is TWO DIFFERENT TECHNOLOGIES.

I give up

 

ok we get it but which one does the intel 6300 card have

 

Guys once and for all R3 laptops will have wireless capability in the future, now they don't, and none have built in transmitters at the moment, Dell will offer them sometime in the future as an option for an extra charge, so for anyone who already bought the R3 he DOESN'T have WiHD

 

well I'll be more specific in my question, does the intel 6300 have wireless HD capability

I new that;s why I bought it. I't in the R3 so doesn't that ability transfer to the R3 ? or am I just totally wrong here

I was talking about Wireless HD (the Sibeam one ) and not widi.
So is the transmitter there in m17x r3??

 

That's what I explained 2 posts back, at the moment no R3 has a built in WiHD transmitter, it will be an option sometime in the future, so if you get the R3 now or already have it you won't have that option.

 

this thread has been pushed way off topic. last time i checked, it was about the 460m and 6970 and the intel GPU.

you want to discuss wireless display, do it here as cloudfire took the time to explain it. i suggest everyone who is arguing about this take a moment and re-read the info he posted. He took the time to explain it, instead of bickering, check it.
