DV6z-7000 AMD A10-4600m Crossfire Performance

My combination actually works the opposite of what you're both describing. I know it could simply be because of the Lenovo drivers but when crossfire is enabled I see the iGPU doing 75-100% of the work most of the time, while the dGPU only does at most 35% occasionally. I wish the dGPU could be utilized more.

 

i wonder what the heatpipe configuration is with the dgpu's

ill have to tear my apart lol unless anybody here wants to

 

That's because the 6620g is way more powerful than your dGPU. When the power difference is too big then using weaker GPU would just slow the stronger one down. The only reason why 100%/100% would be ideal for the 7660g and 7670m is that they're pretty evenly matched in power.

 

Ah, that makes perfect sense! I figured that was the case but wasn't 100% sure. Thanks for confirming.

 

last i checked, crossfire needs full screen to run.

is heaven benchmark full screen?

 

I had no idea it only worked fullscreen.. It does normally run fullscreen, but I had it windowed so I could see the AMD system monitor. (even with the 'stay on top', it doesnt with full screen)

 

yeah, that's why. xfire doesn't work in windowed mode.

you can click the REC button in system monitor to record data to text file, then you can check txt file for gpu usage after benchmark is finished.

or if you have external monitor, you can do dual monitor, with one full screen benchmark

 

Can use MSI Afterburner to monitor both GPU while gaming right?

 

Do crossfire work on non directx 11 games with the new driver? Just run full screen D3 on old dv6z , right click the tray icon to check crossfire icon but seem the icon is not appearing.

Edit: just toyed kombustor with my old 6z

Dx11 and Dx10 full screen both show the crossfire icon thingy on right top corner

Dx9 is no crossfire.

Kombustor can actually drive 90%dgpu + 100% igpu lol.

 

Hey Guys,

I have a DV6z A10-4600 with the 1GB Discrete,

While playing Test Drive Unlimited 2, Im using AMD System Monitor, My AMD Radeon HD 7670M Utilization hits 99% while the AMD Radeon HD 7660G + 7670M Dual Graphics Utilization is at 2% is this normal? Is the Discrete card suppost to be doing all the work, is it bad to be at 99% load, Temperatures are fine...

How do I know if crossfire is working??

 

if TDU2 is dx9, then xfire will not work, and you will see 99% load on dgpu.

if there are dx10/11 features, and you enable them, then xfire will work.

running 99% on dgpu is normal. that's how it runs when you turn xfire off.

you know xfire is working when it has a stable load over 50% on igp.
some games will max out both igp and dgpu in xfire


i remember one of the catalyst release notes said xfire would support dx9. So far, I have not seen that actually work.

 

Thanks for your reply!

Yeah TDU2 is DX9, But I read online that it supports CrossFire, AMD Catalyst has a pre defined profile for the game, I enabled it and its now running from 85 to 99% DGPU load..

 

Crossfire support has nothing to do with the API. DX9, DX10, DX11, it doesn't matter. All you need is the proper driver support to allow for crossfire in said game.

A lot of modern games are on the DX9 API but have crossfire support: Skyrim, MW3, Crysis 2 (it's not technically DX11, just some patch up work on DX9).

Whether the game can utilize crossfire depends on AMD's drivers and HP's drivers, and more so on the latter. AMD generally released crossfire profiles within 2 months but HP can take upwards of 6 months+ to release their version of the same drivers that you can download.

 

Okay. But the game is old, Well from 2011 so the drivers should be out again. I clicked on show dual graphics logo when aviable and of doesn't come out during gameplay, How else can I tell if its crossfiring? All I see I'm amd system montior is load on the 7670m and the 2% load on the 7670g + 7670m....

 

You can try MSI Afterburner and see if both GPUs are getting loaded.

Alternatively, you can browse thru the text in the driver releases to find if your game is supported. Remember that Trinity crossfire support is new and it can't utilize older crossfire profiles because of the VLIW4+VLIW5 architecture in your setup.

 

Dual graphics (the actual name of hybrid crossfire/asymmetric crossfire/etc.) doesn't support DX9 (scroll down to Q5 in the FAQ).

All the performance you're going to get in TDU2 is from the discrete card.

 

I'm guessing this applies only to asymmetric crossfire?



I know you can get crossfire profiles regardless of the API.

So AMD is officially limiting asymmetric crossfire to DX10/11?

 

I believe AMD said they were adding support sometime in the future when Llano launched but I don't remember the specifics.

 

Thanks again for all your replies!

I'm going to download MSI after burner as sugguested to monitor, The game runs perfectly but I just wanted to know why crossfire wasn't working..

 

MSI After Burrner Shows 3 GPUs.. Their all 7670M, But where is the 7660G? And why 3 GPUS??

Here are some screen shots so you guys can help me, Lol, Thanks again!

 

It's a bug or something. Happens to me on my llano dv6z too.

 

translation:
we are terribly understaffed and lazy, and will probably never have dx9 xfire support on your llanos or trinitys.
By the time we do, you will have bought an Intel Core laptop already

 

And you'd expect that without Dx9 support, at least dx11/dx10 would work right (i.e. with far less microstuttering). But no, they don't. 1 year later and Llano dual graphics are still garbage.

It probably makes sense on AMD's part due to the relatively small amount of people running dual graphics, but still... Disappointing.

 

"AMD Radeon dual graphics support that delivers a performance boost of up to 75 percent when adding a discrete graphics card to the APU. The AMD Radeon dual graphics option also offers support for DirectX® 9 for older game titles, and uses new AMD CrossFire™ Technology Profiles for easier updates."

Second-Generation AMD A-Series APUs Enable Best-in-Class PC Mobility, Entertainment, and Gaming Experience in Single Chip

 

^^^ yeah, that's where i read it .

where's our dx9 xfire, AMD ??!

 

see the way trinity is setup with turbo core 3.0 i dont think it will ever run 100%/100%

most ive seen is 15-20% igpu and 95-100% dgpu for xfire...trinity probably turbos it down

not really totally sure on that theory lol haha


was this the same way for llano + dgpu?

 

^ another reason to choose the 7730M over the 7670M.

Crossfire maybe an advantage with the 7670M, but if anyone is to run just the dGPU then the 7730M has newer GNC architecture and built on a smaller process making it run very cool.

 

yeah, you don't know what you're talking about.

in order to keep within the thermal envelope, the apu will dedicate more resources to the igp.

so in the case of the A10, you will see the cpu pinned at 2.3ghz, while the igp will be running up to 100% in xfire with the 7670m.

I've seen some games only load up the crossfire to 75%. It depends on driver and game code.
But I've seen games where both igp and dgpu run 95+% simultaneously.

If what the OP says about subjective performance (fluid performance) is true, I would pick the crossfire setup over the 7730m.
The difference between llano crossfire and trinity crossfire is that the latter is more symmetrically matched.

 

which games max both out? i wanna test those

 

maybe it is working on desktop , but who in the right mind will crossfire two weakkkkkkkk gpu?

 

Anybody have any issues installing 12.6 cat drivers?

Mine froze and have to do a system restore

I guess it only likes the latest HP graphics drivers from the support website

 

had the same problem.

i solved it using a ms repair disk i made

 

12.6 screwed my whole machine up...then i realized this is still an HP machine lol...

i loaded 12.7 beta seems to have liked it...

so yah people be careful loading 12.6, id recommend installing the latest cat driver on the HP website first and IF you want try 12.7 beta but otherwise DONT install 12.6.

 

ran heaven benchmark got this result = 844



using amd system monitor looks like it just ran on the discrete 7670 around 70-90% very little on the 7660g maybe less than 5%

 

ran 3dmark11... can confirm dual graphics is working...both the 7660g+7670m are running 100% in amd system monitor

temps were about 75 C not bad

got P2147

 

wow, that's great, any chance of some game benches? would love to see how this compares to the 7670m on its own

 

i doubt it.

According to notebookcheck, at 1280x1024 setting,
7660g alone would get like 13fps
7670 alone would get like 13 fps

you got 33fps, so it looks like both gpus were working hard.


if amd releases good drivers regularly, you could have gt650m level performance on games.

 

yah I just picked up max payne 3 on a steam sale, once it finishes downloading (10 hrs left lol) ill que it up and run FRAPS. also got BF3, so when I get time this weekend ill run them.

12.7 beta has been running well, also been playing with the dual graphics gaming profiles in CCC


edit: so far im getting 30fps in max payne 3 (avg 26 fps)

1366x768, dx11 is on and most everything is set to high, ill put a screen shot in later...

amd system monitor just shows the 7660g active but im guessing by those numbers both are working in Xfire

 

i have to tell you this laptop is awesome everything works smoooth!!!

just gone done a great session of BF3, max payne 3, heist, medal of honor... no problems

so back to BF3 i set everything to high and got 30 fps, definitely playable and smooth!

 

Have you played BF3 multiplayer yet? How's the crossfire performance?

 

i get about 30 fps using fraps and settings are on a mix of medium and high
( for multiplayer)

though im not even sure crossfire is enabled lol

 

updated score P2207

hmm wonder why the physics score went up so much from my previous post...

maybe cause nvidia physx driver was loaded when i installed max payne 3? lol

 

got P2243 with 12.8 drivers

anybody test any other games?

also is it possible to specify the amount of allocated memory to either gpu?

so to my understanding..... the igpu (7660g) gets 512mb and the 7670m gets 1gb?

is this correct?

edit: hmm cause in Max Payne 3 it says I have 2048mb of memory available

 

from what im reading from this thread it seems that the A10 has hybrid corssfire with the 7670m and not the 7730m? does the 7730m alone perform better then the 7670m + 7600g?

 

It all depends if hybrid crossfire works for that certain game. As of right now the consensus is that 7730m doesn't work for hybrid crossfire. Though it does pretty well on its own since it uses GCN arch.

Like for crysis 2: (7660g + 7670m)

Dx9 I get about 24fps
Dx11 I get about 42 fps

 

would drivers enable the 7730m to work with the 7600g or is it inherently flawed due to different architectures? but what your saying is basically some games its better then 7730m and some is worse right

 

overall the combo of the 7660g+7670m is better than the 7730m because the 7660g+7730m doesn't do crossfire

im using 12.8 but 12.7 beta drivers are good as well...it can only get better.

this thread will better help you understand about the 7730m

http://forum.notebookreview.com/hp-...v6z-7000-amd-a10-4600m-trinity-review-25.html

 

So i looked at notebook check and it shows much better performance for the 7730m vs. the 7670m.. id imagine cooler and more efficient as well.

 

yah its the better option for single card, since its GCN arch, plus it has 2gb of memory.

 

so i got overclocking working in MSI afterburner for the 7670m

here is my 3dmark11 score



just went with a basic OC, I sorta went by the 7690m default clocks....it didnt seem like it got much hotter but i need to do more testing with other games/programs to make sure 700/1000 is a good stable clock. though i probably wont use this for 24/7 i was just curious if it did actually OC and it did!



also new HWmonitor shows 4 core temps now
