How come the 780M is almost same as 880M?

According to THIS, it seems that the 880M is only slightly better in benchmarks than the 780M and in one case the 780M even beats the 880M. I don't get it, the 880M has a higher clock and more RAM and is 1 year newer, how come it doesn't destroy the 780M and barely beats it?

 

You're a year late to the party. 880m is just a debacle. Avoid it like the plague. 980m is the way to go. A lot faster and a lot cooler and lot less power draw.

 

It's almost the same because it is the same. The 880M is just an overclocked 780M. They are both GK104.

 

Yeah.. this is another example where newer tech isn't always better. At the end of the day they are the same card, or a rebadge (gone bad). Some of the stock benchmarks show 880m to be about 5% more powerful than a stock 780m which is about right considering it's the same card with higher clocks.
The problem with the 880m is for whatever reason they are blast furnaces. The 780m can overclock much higher and operate far cooler than it's gimped offspring.
Hopefully they aren't giving you too much trouble.

 

One generation usually doesn't destroy the previous anyway. That's why I think it's better to upgrade every two years, not yearly. 880M was particularly bad, but even if it wasn't what people expected, 780M to 880M still wouldn't have been worth the upgrade to me, 780M to 980M yes. I didn't upgrade to 880M from a 675MX because I didn't see the value.

That's my view of hardware advances. Gotta take into account of software. In one year has games and software improved enough that would require an upgrade? I've only seen that happen once, when Crysis 1 was released, that utterly destroyed everything and upgrading still wasn't enough, hahahaha.

 

Haha yes, took the words right out of my... fingers?

They are one and the same in every way, except clockspeed. With overclocking factored into the equation there is literally no difference at all between them (except in name and software support of battery boost).

Forgive me for my ignorance, but if the 880M was barely more than just a rebadge of the 780M, then why is it much more prone to overheating, throttling and poor at overclocking than its older cousin?

Thanks!

 

Not true. 880M runs much hotter at the same clocks despite 780M generally needing more voltage to achieve the clocks the 880M can do. The 880M likely used desktop leftovers which are not suitable for a laptop with limited heat dissipation potential.

Precisely because it is an overclocked, overvolted 780m. It runs hotter, has less headroom to overclock etc.

 

880M runs at lower voltage than 780M

 

It does?! Then why does it get hotter?? I always assumed it had a higher voltage.

 

The only real logical explanation is leakage. The cards draw more power than 780M despite a lower voltage and output more heat than 780M at the same frequency. Those chips aren't suitable for laptop usage. NVidia knew this from the start if you examine the way the vbios dynamically adjusts clock frequency up and down but still averages 950ish overall (as long as the thermals stayed in line which wasn't the case in most machines). Those cores would have made great desktop cards though, they overclocked like crazy, the heat was just impossible to contain.

no I was actually happy to read this. I was always ticked off that I have a 2 generation old pair of GPUs but now with said, seems like I am only one generation old

 

What's funny, is if you go to a store and look at two laptops (Alienwares for example) one with the 780M in SLI and the other with the 880M, the 880M equipped laptop would cost an arm and a leg more! Even if I would try to sell my Alienware, I probably would get more if I had 880Ms as the average joe usually thinks newer GPUs is like a night and day difference and would look for the one with the 880s rather than one with the 780s.

 

Yeah I got screwed by a week on a system with 780M cards and had to get 880M cards, replaced them twice before I got fed up and paid Sager to upgrade me to 980Ms. You can easily push the clocks on 780M to 880M boost with a small voltage bump and lower temps.

I had no idea what I was getting myself into when I ordered the 9377 with 880M cards instead of the 9570 with 780M cards... The 880M was too new when I got my machine.

Well, that's not always true. The 680M was quite superior to the 580M, as was the 780M to the 680M.

 

Same with the 980M vs 880M. Huge improvement.

880M was the odd one out of all the flagships over the past few generations. The only one to offer such a tiny and more-often-than-not non-existent performance boost against the previous flagship.

 

880M is significantly faster than 780M when you achieve full boost through vbios mods and it has more overclocking potential than the 780M as well. Hell I used to run 850MHz @ 0.887v which is faster than a stock 780M and cooler than a 780M due to the insanely low voltage requirement for that core speed. It sucks out of the box because it's a throttling mess but make no mistake that when it's unchained and allowed to draw the power it needs, it smokes the 780M and that gap widens even more in the crappy console ports that chew past the 4GB mark. Heat and noise were totally unacceptable to me though and I am very happy with my 980Ms.

Hardly though, once you're at the point of modding each, almost every modded 780m had a very clear edge on the 880m's in performance.

 

Sustainable performance without a doubt but after a few driver updates, the 880M was stabilizing and matched the 780M clock for clock as it should have from the start, the heat was just too much for anything other than a quick benchmark. I ran so many tests and compared results and graphs and everything with my 880s. The second pair actually wasn't that bad until they started crashing and disappearing from the control panel and all. I don't miss those cards but I had a modded vbios that ran 780M clocks and there was no significant difference between the two cards other than the 10C average hotter temperature of the 880M.

Either way, I'm glad to have my 980Ms. They haven't had any misbehavior issues other than when I stressed them too much and they throttled at 87C.

 

Yeah, far too much fiddling was required for the average user and then the temp issues.
Oh well. We live and we learn (not to trust Nvidia)

 

AMD R9 390X enough said

And AMD R9 390MX for me

 

doubt it. ive been trying to sell my whole rig with my 880m for only 900 bucks. hard drive, ram,cpu and all and no one will budge. words gotten out on the 880m. when i get a new laptop, this laptop will probably just be laying in a closet collecting dust. its cursed

 

Really? Nobody will take that thing even for $900? They lowballing.

 

all my friends are poor and craiglist people are stupid and don't know much about gaming laptops. they just want facebook browser machines lol

 

You're peddling to the wrong crowd. You'd have much better luck trying to sell it here.

 

i probably will. even if people dont want the 880m, they could still use it for parts lol. the 8gb of vram comes in handy though

 

@Phase, Luna is looking for a 8258... Might be worth hitting her up about it..

I have noticed that if you overclock the GPU only then the temperature of decreases by 10C.

The more you overclock the GPU the lower the temp. gets. However, to an extend of 70Mhz only.

After that, it becomes unstable.
