HD 7750m vs. gt 650m

Alright then, my envy 15 has a 7750m card, @ stock 575/1000 it gets
this in 3dmark11 and this in unigine.

With an OC to 667/1000 it gets this in 3dmark11 and
this in unigine.

I was just wondering, how does it stack up to the 650m ddr5 and previous gen cards


i forgot to mention this is with the 12.7 beta drivers

 

Notebookcheck shows an average of 2300 for the 650m at stock for 3dmark11.

(a reminder that notebookcheck gets the lowest possible scores so that should be considered the absolute worst the 650m would ever do)

Most savvy users are getting fairly impressive overclocks with the 650m and the latest set of drivers. They are reporting 3dmark11 P scores around 2800-2900.

I'd say the results indicate that the 650m is a step or two above the 7750m.

 

I'll run unigine this evening at stock clocks and max oc's (1085/1100)

 

Is this correct ?

7750m > 640m

7770m > 650m

7850m > 660m

7870m > 670m

7950m > 675m

7970m > 680m

I am not saying who is better but who is competing with who.

 

hmm how much do u think official drivers will increase score and OCing ability? Right now im unofficially OCing with afterburner since there are no official drivers from amd out yet.

alright thanks man

 

Highest i've seen the 7850m(not 7750m) do is 3000 pt(OC) on 3d mark 11

how does that compare with the 660m ?

Edit: I just checked 3d mark, 660m oc seams to be doing 3000pt too.

 

i gotz another question. doesnt nvidia have physix which helps to get a higher score in 3dmark11 but its useless for most other stuff?

 

That was in vantage and is off by default.

If a review site uses vantage with it on, never go back because they are worthless at benchmarking.

 

ah alright . and then another thing i heard is that kepler is good at dx11 stuff so thats why they got higher scores than previous gen cards but overall perform like the previous gen. Like 650m scores quite a bit higher than 560m but it basically ties in performance?

 

I HIT 27XX 3dmark score with 650mGT with stock bios. Im over 29xx with updated bios

650mGT > 7750

 

:| oh noes haha. how did amd excel in 7970m and is failling at 7750m but anyway, how r ur fps in games? so far what i been able to test out, im getting around 40+ fps outside in skyrim with default aa/af and ultra preset

 

Here's results with my GT 650m DDR3:

Stock Clocks (CPU 2.3GHz, GPU 835/900)


Overclock (CPU 3.1GHz, GPU 1085/1100)


I can get over 2900 3DMark11 with CPU/GPU overclocked: http://forum.notebookreview.com/sag...-w110er-first-look-review-82.html#post8636234

 

Roughly, yes... although I think the 675m will be poor competition for the 7950m (if it ever releases) due to the 675 being a rebrand, especially when OC'd.

 

hmm why is the 3dmark11 scores so different where as the unigine are under one another? so i guess 650m is stronger... can drivers make thatmuch of a difference? maybe enduro is creating problems?

 

Notebook check rates the 7770 < 650mGT and 660. I don't know what to tell you. I would go for the better drivers and game performance regardless of synthetic benchmarks. I have the 650, I like it. There a loads of GPU's that are faster but it does fine for BF3, COD, MMO's, etc.

 

notebookreview for the new cards is trash. it saying the 7770m is 32w where as the 7750m is 38w yet the 7770m is faster lolol

 

Someone with a retina MBP got 3248 3dmark11 with a i7 2.6ghz and a 650m at 1200/1649... insane its as good as a previous high end alienware

 

How did they manage 1200MHz for the GPU? It's currently locked to max 1085MHz.

 

nvidia inspector

 

we're the keyboard keys melting? Those rMBP get HOT.

 

Nvidia inspector can unlock the Max over clock.
The temps were high for the CPU but the GPU ran within reasonable temps, the CPU ran hot at 100C the GPU temp was only 80C... pretty insane 1000 more points in 3dmark11 with only a GPU over clock and only 4C hotter.... I think apple has me sold now

 

I use nVidia Inspector but it only allows for max 1085MHz. And it's a mystery how it allows that. Because it only says "+135MHz" which technically should be 970MHz (stock is 835MHz). AFAIK the M14x is the same way. What needs to be done to unlock max overclock? P8 state allows to unlock max and min clocks, but P0 state does not.

 

I am pretty sure he is using beta drivers from LaptopVideo2Go and Windows 8, there has been some talk that W8 gives you more OC.. I don't really know for sure though

 

Ah. In any case I don't really care because I use mine at native 1366x768 and it's more than adequate at that resolution.

 

ah is there some kind of unlocker thing for amd?

 

this guy hit 3248 3D mark 11 with an overclocked gt650m lol http://forum.notebookreview.com/app...-results-gaming-benchmarks-2.html#post8656736

 

wthhhhhhhhh!?!??! stupid mac would allow unlimited OCing .

 

i am sure there is a way to unlock any 650m

 

i dont care about that i wanna unlock my 7750m

 

lol

 

@PaKii94: Send me your VBIOS and I take a look at it.

 

oo ok.... how do i get my vbios lol

 

Note his 105C readings on that processor... That's not just a warm keyboard.
The CPU is at danger zone.

The GPU could actually handle more if the cooling system weren't struggling with the rest of the laptop.

This may actually be a recipe for disaster for MBPr users.

 

Ah, nevermind, I downloaded it and took a very quick look at it... It's not clocked too high, there should be some headroom. 3d voltage is 0.95v? Could be set to 1.0V it seems...

Anyway, the vbios is part of the BIOS, and your BIOS is RSA signed, so you might end with a semi-brick in case I modify it... you never know with those stupid HP BIOS, so I don't know whether you're interested.

 

hmm if it does become "semi-bricked" what would happen to the laptop? and i do got accidental warratny... would that possible cover unofficial bios's ?

 

Usually you can still recover, in many cases you can even recover from a complete brick... but it's a bit a PITA if it happens.

 

if u wouldnt mind helping me out if i do brick it then ill take the chance

but yeah if this will totally eff up my comp then im effed haha

 

a gt 650m is a good overclocker as it is like a basic card clocks for the new 28nm process. In simple terms a gt 650m oc with same performance as a 675m. Its like when core 2 duo came out.

In a way 670m and 675m being so slow meant 640m and 650m and 660m had to be very low powered cards. I doubt a gt 650m needs much cooling as it is a basic card for a 28nm manufacturing process. 650m takes similar power to a gt 540m.

 

Yeah I just installed Inspector and noticed the P8 state too. Is there a way to lock the GPU into the P8 state and just OC from there?

Do you think you or someone can give me a link to where you found this information? I might just be willing to try it, myself.

 

Lol, an incredibly OCd 650m GT with GDDR5 can barely keep up with GTX670m with slight OC, if anything at all.

 

but the point is it can reach that high haha. could the 550m ever reach 570m status?

 

My HD5870m when heavily OC can reach stock GTX570m or a bit more performance too. And my card is even older.

I would be impressed by what you are trying to get, but when the GTX660, GT650 and GT640 are essentially the same card save clocks and memory bus width/type, its not really that impressive.

The GTX660 core is a powerful chip, so it is no suprise it can reach the big bro when overclocked, even if the bigger bro happens to be older tech.

Just as a GT555m, depending on model, could reach GTX560m performance, and a 560m ocd could reach stock 570m etc.

 

yeah i get what ur saying lol but stupid constraints dont usually let a lower card reach that high up. but whats different here is mac users can OC it that high while others cant

 

I am pretty sure the gtx 680m and 7970m take less power consumption then the 670m lol. Anyway my point is gt 650m gddr5 is like a 35w card power consumption wise and the 670m takes more like 90-100w. So if you oc the 650m by 50% you should get more performance on the 650m at just half the power consumption. Not bad I say.

 

A reminder, the 570m has gotten to 4k 3dmark11... as nice as the 650m/660m is, it's only gotten to 3500.

The 670m is a factory-OC'd 570m.

Yes, the 650m takes less power... however, with optimus its not really that big of a deal. Simple struth is that 650m-equipped machines do not have higher battery life while gaming as most of them have weaker batteries.

Furthurmore, most 670m-equipped machines also have better cooling.

The 650m and 660m are very nice... they just aren't a 670m which is still in a completely different league.

.............................................................
I just had to laugh there. 670m laptops overheat from what I read on another thread.

670m is not in a completely different league. 660m beats the 670m on some stuff. 570m oc to 3dmrak11 score of 4000 should take around 220w, 650m/660m oc to 3dmark11 score 3500 should take around 150w. if anything the 660m or 650m or are on another league to the 670m.

IN perspective actual power consumption on the 670m card alone takes around 50w more then the 660m. Heck according to notebookcheck the 7970m and 680m take less power consumption then the 670m. 670m's mainly throttle as there is not many power supply's big enough to supply it. Imagine how power hungry a 675m is.

 

Good luck reaching our resident genius with this argument. He was stating in a different thread that the 660m performs the same or better than the 675m. Picking and choosing pieces of information to "support" his argument. Don't worry though, he knows he's right!

Again, this isn't the Power Conservation Forum. This is the Gaming forum, and we're concerned with performance for, you know, gaming.

 

Theres no reason to get the 670m for gaming. So using your logic this being the gaming forum and not power conversation forum, you would get the best tech. Kepler has far more advanced features.

This is what he said when 680 came out:
Today, the first Kepler - GTX 680 - is on shelves around the world!

Three years in the making. The endeavor of a thousand of the world's best engineers. One vision - build a revolutionary GPU and make a giant leap in efficient-performance.

Achieving efficient-performance, great performance while consuming the least possible energy, required us to change our entire design approach. Close collaboration between architecture-design-VLSI-software-devtech-systems, intense scrutiny on where energy is spent, and inventions at every level were necessary. The results are fantastic as you will see in the reviews.

Kepler also cultivated a passion for craftsmanship - nothing wasted, everything put together with care - with a goal of creating an exquisite product that works wonderfully. Let's continue to raise the bar and establish extraordinary craftsmanship as a hallmark of our company.

Today is just the beginning of Kepler. Because of its super energy-efficient architecture, we will extend GPUs into datacenters, to super thin notebooks, to superphones. Not to mention bring joy and delight to millions of gamers around the world.

I want to thank all that gave your heart and soul to create Kepler. You've created something wonderful.

Congratulations everyone!
Jensen

 

There's no reason for you to so adamantly dictate what you believe other people should do. How about understanding that people will have different world views and you should respect those while holding true to your own beliefs.


In other words, move out of your parent's basement and get a clue.

 

meaningless nonsense all over the place! hey look I can do it too!!!!

We should race your Impreza (did you say you sold that?) against his nissangtr. He will win because his is like a factory OC'ed 570m while yours is like a lower powered one that consumes like 30w but is so much better. apples are oranges. grapefruits! aliens! TACO BELL!!!!!!!
