AMD C-50 CPU and 6250 GPU performance(Acer 522 review)

ha! My Dragon 32 was the best ever

 

Ok, you won!

 

haha i showed my age

 

it sounds so funny but its true )

 

Hi all,

I keep reading about how this amazing little C-50 handles HD video so well. My experience is a bit different. I can play 720p from Youtube with no problem. Vimeo is a disaster. The most serious problem is that iTunes HD content is also a disaster. I've tweaked everything and adjusted every slider and I can't speed it up. Can anyone with this setup buy and watch a TV show in HD from iTunes? I just bought a couple of episodes from Heroes season 2 and I have to watch them in SD.

Second problem: tearing during horizontal motion in any video. Is there a video playback setting that is equivalent to the vSync setting in gaming?

Edit: I just set the refresh rate to 50Hz (was 60Hz) and the tearing is much better now.

 

everyone make sure you disable "aero peek" to gain the most performance while watching hd vids and gaming. great optimization. right-click taskbar and go to properties. make sure aero peek is unchecked.

 

hey, just curious...here is a japanese coder with his setfsb software...maybe his software could overclockl our beloved apu? it said to support amd a50m chipset...but, he want a donation so that the software could be fully functional...cek this SetFSB_HomePage

 

Someone in a german forum tried that already, but it was not working. At least in version 2.3.166.131, which was supposed to support A50m already. That was end of June.

Edit: The current version is still the same as the tested one in June, but who knows. It was tested on a S205 though, whereas I believe the used PLL is the same, because it is built into the chipset.

I contact already the Author of this Software.

He told me that he is not able to do this. At least at this moment he wont do.

Maybe if more people ask him....send him a mail ---> [email protected]

 

New GPUZ is out and fully apu reading supportet ---> Download TechPowerUp GPU-Z v0.5.5 | techPowerUp

 

have you guys seen anything about turion power control? i tried the updated version, and supposedly brazos is working. i cant seem to get it running properly. cpu frequency changes arent working, even downclocking. vid adjustments are mostly leading to system freezing, even voltages that work with brazostweaker. but forum posts state that it is indeed working for e-350 users. witteks any ideas?

 

e-350 in which brand? acer?asus? lenovo? or else? i think every hadware tweaking software have mobo dependencies

 

Hi amdfanTO,

unfortunately TurionPowerControl is only designed to work for AMD family 10h and 11h, whereas Brazos is 14h. These families do differ a lot.

I'll definitely will have a look into the sources, since it seems to be a neat program I might be able to learn a bit from it.
As far as I know, there is currently no program available, which is able to change the NB VID on all Brazos systems (BrazosTweaker does it at least for IdeaPad S205, Acer W500 and ASUS 1015B).

Next shot will be to change the timing during NB voltage changes.

Great stuff man. Keep it up. It really bothers me that these manufacturers feel the need to block out users from improving their systems. If it wasn't for you I'm sure there would be many AO522 users suffering from overheating issues like burnt chips and throttled performance. If anything you may have prevented a class action lawsuit against ACER for a serious defection in this product.

 

I have a question. When I run "can my system run this game" the 522 passes on all points except the cpu. Of course , you can't gauge the 1ghz processor as a fail as games that supposedly failed, play great. For example, Fallout 3, BioShock and Oblivion. What's interesting is that the video card is reading as 1.9 Gb of video ram available. Also the graphic driver updates have the shader versions at 5.0.

So, with Bioshock, it will be sluggish unless you activate vsync. In doing so, you can have almost everything on max without lag or stuttering. It will fly.
So everything high, the only thing I cut back on is shadow maps and forced lighting. It can take on multiple enemies with no lag. So, earlier in this thread, people were talking about the cpu, well it's a hybrid and does things that mirror larger cpu chips.

It has too, because games that supposedly fail, play flawlessly. Even oblivion with mid range specs, no problem.

My question though, beyond sharing my experiences, why is my 522 reading at 1.9 gb of video ram?

I have windows 7 64 ultimate, 4 gig of ram, ssd drive and 11.8 plus the latest bios.

Just wondering.

 

i think it's the shared memory...basically the system dedicated 256mb for 6250, and for addition (if u have enough ram) the system will give the vga a privilege to 'share' the remaining ram by a percentage...so, in ur case, the 1.6G can be used by vga if not being occupied by ur system

 

Forgive my newbieness but where do you enable vsync? I dont have ccc but something amd vision engine control centre and i cant for the life of me find it?

 

Thanks, Juan, I don't know what you mean by vga, except for the ancient monitors, but brad, your vision engine control centre is CCC.

Vertical Refresh is Vsync. So, I have my settings at off,unless application specifies.

This basically gives me the option to turn on/off vsync within the application while not having it constantly on.

vertical refresh has a slide toggle in the gaming options above performance.
it will give you a brief description of each choice within the toggle slide.

 

I should add to above comment about bioshock flying, and having everything on high, I do have the resolution at 800x600. Still, it looks really good.

 

Ok cheers, so i set it to off in ccc but within games enable it?

 

I wouldn't set it to off, but to "only on when application needs it" within ccc, the games tab , that way you can access the vsync in the game application but it isn't always running,
eating up resources, grinding away endlessly. Some games like BioShock have an off and on vsync feature, in this case, I am not sure if having it off in ccc would lock up that option. Otherwise, choose vsync for getting good results in BioShock, But, some game programs may use it without a gamer option present in the options menu, in which case vsync would be implemented by the game. Or if you had it off, then the game would not be able to access that feature, vsync. So, ultimately it's a case by case, but vsync is almost necessary in some games while in others it can be a unnecessary frames per second killer.

My writing above seems convoluted, so, keep it as application needed and then experiment with each game being set up. But, if you have it off in ccc, then there is no tweaking, it's just off.

Hope that helps.

 

wow, what a diff, playing fallout vegas now at 1280x720 and its pretty smooth, actually its not that smooth shame there are limited resolutions available as 800x600 looks naff

 

Here is something odd. I wanted to see what an older game would do on the "can you run it" website , so I tried Age of Empires 3, which plays flawlessly and needs a pentium 3 equivalent. So, here is what I got:

You Have: 1.0 GHz Performance Rated at: 1.4 GHz

Rated at 1.4 GHZ. Eh? I don't have a c-60 , so what is this?


What does this service do?
This service analyzes your computer's system information and compares it against a product's specific minimum and recommended requirements. It then instantly provides both a summary and a detailed analysis of your system.

 

its providing a theoretical perfomance comparison. the c50 chip performs similar to a 1.4ghz chip relative to the games needs. mine shows up as 1.8ghz. which makes sense because its not really 2ghz of power even though its 1ghz x2 for dual core.

 

I see, because it's a dual core chip. So, interesting the dual core aspect of the chip allows performance that in fact goes beyond the 1 ghz mark. That is why I can play a few of the 2ghz plus games, dual core. That's why the wei index is off? I wonder why your rating showed up higher? Did you test the age of empires 3?

 

I'm having a bit of trouble running the original Far Cry on the C-50 tablet in my signature. It plays fine but has terrible screen tearing. I enable VSYNC in the game options and also in CCC but it's like it ignores my settings. CoD4 and Halo both use VSYNC fine.

 

use d3doverrider
google it and enable vsync and triple buffering
works on all games except ue3 engine titles

 

Guys, I have somewhat of an issue. Today I bought a AO522-BZ436 from bestbuy in sale. The thing is, when I run dxdiag, instead of the C-50 it shows as a C-60 and the graphics, which are supposed to be HD6250 instead show up to be HD6290. Is this normal or do I not have the right laptop?

Even on the sticker that's on the front of the laptop it says it is supposed to be a C-50.

 

I wouldnt complain looks like you have the newer upgraded model

 

I'm not complaining, that's for sure!

EDIT: Some pages back, a few people said the C-60 posted lower WEI scores, well, that's not true. I get a 3.2 subscore in the Processor category while the original poster claims 2.8 on his C-50.

 

ok c-50 got 3.2 wei cpu ....its the same as c-60 than...

 

c50 is 2.8. c60 is 3.2
i even saw on slickdeals forum that someone overclocked their c60 to gain a 3.6 for cpu. I didnt make an account to ask him. but i'll try to find the link

edit: found it

check near the bottom. posted by "wishingonastar"
any one wanna make an account and ask him how he overclocked the c60?

Wait, HOLD THE F-ING PHONE

Now you can upgrade it to c60?? How about older 522 and other laptop like asus 1015b??

 

lol the wei score on the screenshots is fake...
and also why have yu 2.8 cpu score? i got 3.2

 

c50 is 2.8

 

C50 is 2.8 or 2.9,How do you get 3.2?

 

sorry
cpu 2,8 . ram 4,9 . gpu aero4,1 . gpu game 5,5 . hd 5,6)
so it seems that turbo mode is working in benchmark... but how ram can be faster?

 

i think because the c60 allows a higher clock speed for the ram
the c50 accepts all sorts of memory but limits the clock speed

 

Hi

Im having a few issues with the hdmi output. I bought this so that when I'm away etc and have the chance to hook it upto a lcd tv I can watch some movies etc that ive converted from dvds etc etc but when ive tried it tonight on my samsung 23" lcd which is 1920x1080 regardless of resolution selected its off the screen, being a tv/monitor it doesnt have a auto set button, this new ccc is driving me nuts too

Any ideas?

 

try set GPU scaling....
i has problems with croped hdmi output ,havent try with newer drivers...
if nothing works try VGA is without problems...

 

yeah tried that but couldnt select any of the different options and it made no difference, one of the main reasons I bought the 522 was for hdmi output

 

so it looks like our hopes for undervolting the gpu and overclocking anything in the c50 is nothing but a pipe dream

 

bradmax ...try it like this ..first change desktop res. to lower than native...
than open CCC and find GPU SCALE..enable it than try custome hdmi resolution...
amdfan ..yes i am not positive about overclock too...locked apu ..only hope FSB and that is 105- to max 118(cant confirm yet)...
anyway iam happy with this machine..and futur will bring better machines

 

all I know is I did this with the 722, with the drivers from about two weeks ago, and the CCC of same vintage, and it worked well on my Bravia 46". The newer CCC IS a tad more confusing than about 6 mos ago, but one of the settings hit it perfectly.
I would think just try several diff ccc selections until you get one to fit/scale

 

Hi i just did a full reinstall of windows 7 to 64bit on the ao522. However for some reason i cannot change the resolution to 1024x600 native. It is stuck on 800x600 resolution (greyed out). I installed the latest driver from amd site and also tried the one from acer's site.

Anyone know how to fix this problem?

 

I just watched a 90 minute movie on HBOgo.com. I noted CPU usage about 85% and GPU usage around 10% according to Process Explorer and CPU temperatures about 79 deg celsius, thank you witteks! I thought GPU usage should have been much higher and CPU usage correspondingly lower.

I was more interested in the movie than examining this closely but I thought to post what I know here. Relevant items: AO522, 4GB RAM, Brazostweaked PO 1000MHz @ VID 0.9000; P1 500MHz @ VID 0.7750; Windows 7 SP1 x32, Catalyst Software Suite 11.8, Google Chrome Browser 13.0.782.215 (m), Flash plugin 11,0,1,98 configured to use hardware acceleration.

How to offload more processing to the GPU?

 

are yu sure that video format is supported in gpu codecs... ?
first try youtube..they have that types of videos

 

tagging krishna's response: there are a number of reasons this may be the case, but the first place I would look is the player.
What vid player are you using, does it have options for locking in hardware acceleration? I have found great variance among the best players in this regard. I would first try changing to a different player if you can.
If you're using Netflix, then you are locked in to silverlight - no room to maneuver. If you are downloading the file, what format is it in?
'tis a big topic

 

WEI is not a reliable benchmark to compare hardware. My 522 has a 2.3 score on CPU and I'm pretty sure it's not way slower than your 522s. other scores are ram 4.7, gpu 4.1 / 5.5, HD 7.6.
