AMD Radeon HD 7690M drivers (lenovo)

I have a Lenovo Y470p with a AMD Radeon HD 7690M. First laptop I've ever had. It has this switchable graphics thing to switch between the onboard Intel and the actual Radeon for battery life.

Anyway, to get to the piont of the post. I cannot find updated drivers for this card anywhere. AMD does not have the card on their website and their tool does not find it. The drivers on my laptop are from October of 2011 (from the Device Manager properties tab). The ones on lenovo's site for this laptop say they were from April 2012. After installing them ALL MY GAMES stuttered like crazy so I had to rollback to factory settings to get any games to run.

Is there someway to get AMD to support this GPU or am I better off returning the laptop?
 
I think it's one of those OEM only GPU's, but I read somewhere you can try using the 6770m/6750m drivers for it.

Ah, here it is:
AMD Radeon HD 7690M
AMD Radeon HD 7690M

The AMD Radeon HD 7690M is a fast middle-class graphics card for laptops introduced in 2011. It is at heart a renamed Radeon HD 6750M with a 100MHz increase in memory clock speed on models sporting DDR3 VRAM. Therefore, the GPU is still built in 40nm with DirectX11 support.

According to AMD, select DDR3 models are available based on the faster clocked Thames-XTX chip. The similarly named Radeon HD 7690M XT is based on the same architectural core as the 7690M, but offers higher clock speeds with GDDR5 memory. In essence, the XT variant is a renamed Radeon HD 6770M.

Current 7690M models are available as:
AMD Radeon HD 7690M, 725 MHz core, 900 MHz DDR3 -> 6750M
AMD Radeon HD 7690M, 600 MHz core, GDDR5 -> 6750M
AMD Radeon HD 7690M XT, 725 MHz core, GDDR5 -> 6770M

The integrated 480 Stream processors are still based on the 5D architecture found in the Radeon 5000 series. Therefore, the number of shaders is not directly comparable to the 1D cores of current Nvidia GPUs. General Tessellation performance of the Radeon HD 7690M card should be comparable to the desktop 6800 series. The Stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. The latter two features enable the AMD core to transcode videos and perform general computations.

The 3D performance of the HD 7690M is slightly better than the average GeForce GT 550M and is therefore positioned in the upper middle class as of 2011. Demanding games like Anno 2070 or Skyrim can only be played in medium detail settings and lower resolutions. Even more demanding games, such as Battlefield 3, may only run fluently in low detail settings. Older games like Call of Duty: Black Ops are playable with all settings maxed.

The new UVD3 video decoder supports the decoding of MPEG-4 AVC/H.264, VC-1, MPEG-2, Flash and now also Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos on the AMD graphics card.

Hope that helps a bit.
 
I have an HP with switchable graphics as well. AMD will never support laptops with switchable graphics, however there is a work around i found months ago.

If you can get your hands on generic mobility drivers you just simply install over the top of your existing install from Lenovo. This keeps the switchable part while updating the AMD side of things.

You could simply uninstall the lenovo version and install generic AMD mobility but you'd lose your switching, hence just installing over the top.

It's worked perfectly for my 6770m. Doing a quick google search you can normally find the generic install, for example it looks like softpedia has the 12.4 mobility for download.

As always backup everything though since this isn't exactly "supported".

I think I have the sticky clock speeds bug. In GPU-z its reporting my default clock is 100 (should be 750) and memory clock is 150 (should be 900).

I installed MSI Afterburner and the graph is showing my "max" to be those same low speeds, although the sliders are all the way to the right. I can't seem to figure out what is keeping my Radeon on such low speeds. Any ideas?

UPDATE: when I play a video using mpc-hc Afterburner shows the clocks go up to their max (750/900). If I run a game while the video is paused it works great. If I run a game with no video playing the game runs like crap and Afterburner shows the clock speeds sitting at 100/150. Why is this happening?
 
100/150 is idle clocks. On a laptop you want the lowest power consumption when on desktop (idle mode)...
When you play a game the clocks go up, like they should.

If you like, check Control Panel > Power Options > edit your detailed settings > PCI-express > Link state power management > off.

Thank you all for the help. Let me close this thread off with my solution.

*** PROBLEM ***
(This all started after I changed my energy saving power options from Balanced to High Performance. The problem was my clock speeds would not increase past idling levels of 100/150 unless I had a video player open => games ran at 1/10th of my Radeon's capability)

I can't get leshcat drivers to work at all for whatever reason. I followed his guide to the letter. Once I do a complete driver wipe following his instructions, my system does not recognize the Radeon 7690M => The CCC install will not install the driver.

I rolled back to Lenovo's drivers which have extremely old ATI drivers (from mid 2011) despite the fact they were uploaded to Lenovo's site in April 2012.
*note - the correct drivers for the y470p are the "Onboard graphics driver (Intel/AMD) they are 642 mb!

*** SOLUTION ***
This is in two parts:
1. Enable PowerPlay in the Catalyst Control Center. I selected both "battery" and "plugged in" to maximize performance. For whatever reason, if the actual checkbox for PowerPlay is not checked, then the GPU clock speeds can become stuck idling even while playing games.

2. (Thanks to popeye!) I unlocked AMD Overdrive in the CCC and set my core clock and memory clock to a slightly different value than the stock. This is to make sure the clock speeds can never become stuck. This took me hours of forum searching to find this and it worked.

Hope this helps someone else out, and thanks again to this community for all of your help!

I've not had it confirmed personally no.

I read on many different sites when i was trying to find a solution for my own laptop people saying AMD would not be supporting anything with switchable graphics. I'm unsure if those folks got that confirmed or not.

However on AMD's site in the mobile section for there driver detection tool it does say:
The following notebooks are not compatible with this tool:
Notebooks equipped with switchable graphics

Also given the amount of time switchable graphics have been around (since the 3000 series) it seems to me AMD is content to leave it in the hands of the laptop manufactures.

So personal opinion with a dash of AMD's website and common sense! ;)

I know you've got connections though, if you could get a firm yes or no that'd be awesome.

I was told by AMD it would work on switchable graphics. That message from the detection tool just says the auto detection tool doesn't work on switchable graphics systems, not that the drivers wont install.
 
I never said the drivers wouldn't install, in fact i said so long as you can get your hands on them you simply install over the top so as to keep the switchable part while updating the AMD side.

However you have to find the drivers elsewhere because that tool won't let you download them if you have a switchable system.

Here are the 12.3 and 12.4 AMD Laptop drivers

http://www2.ati.com/DRIVERS/mobile/12-4_mobility_vista_win7_64_dd_ccc.exe

Been loking at all the posts regarding the AMD GPU, more that 47 Pages on one of the HP Forums.
 
Thanks for those links Zip. I'll assume if we change out the release number in the link we can get other sets as well without that tool blocking us. So long as they don't change the rest of the file name.

For example

12-1_mobility_vista_win7_64_dd_ccc.exe
12-2_mobility_vista_win7_64_dd_ccc.exe
12-5_mobility_vista_win7_64_dd_ccc.exe
12-6_mobility_vista_win7_64_dd_ccc.exe

and so on.
