Radeon HD 6770m Vs GTX 260m

I was wondering how much better the gtx 260 is over the radeon 6770. Is the difference huge and noticeable?


Edit: Not gtx 260m but gtx 260 for desktops

 

Desktop GTX 260 is comparable to a mobility 5870M, which is clearly a lot faster than a mobility 6770M. If I had to venture a guess, I would say it's around 40% faster on average.

 

Depends on which GTX260. Noticable yes, but by tweaking the 6770M you could help close the gap.

 

6770 trails just a bit behind the 260m, but the 6770 is fairly better in some ways, as the 260 is only Directx 9 compliant, 6770 is a good card that will hold you for the future

 

The 6770M is about the speed of the desktop 9800 GT, so find some benchmarks which compare the 9800 vs the GTX 260.

 

No. This is far from correct. A desktop GTX 260 is well beyond a 5870M. The 5870M is like a desktop HD 5750 which puts it just barely faster than a GTS 250/9800GTX.

This is correct.

No, the 9800GT has no power limiter on it when it draws power from your PSU. The GTX 260M, even after overclocking, still falls behind the 9800GT. The 6770M would probably manage around the 5670 territory. Which would be something like a 9600GT in most games.

 

Actually you are slightly wrong. The 5870M is equivalent to an underclocked Desktop 5770. It has the same number of shader cores and such and with enough voltage added into the 5870M, you can match clock to clock with the 5770 after an OC.

 

Which is still significantly slower than a GTX 260. If you look at the specs and performance of a 5750, you will see they are the same as the 5870M at stock. 150mhz slower core speed and 200mhz slower memory speed will cause anything to drop in performance. Even after pushing back up to the level of a 5770, the GTX 260 was proven to be considerably faster.

The 5770 loses to the 4870 most of the time, which was slower than the 260 as well.

However a GTX 260M is considerably slower than the 5870M. That's where I am right and that's what matters here.

 

The point is right but the 5750 = 760 Shader Cores. 5770 = 800 Shader Cores = 5850M and the 5870M.

A GTX 260 216 Desktop is slightly better than the 5770.

260M though is more like the GT 555M in my opinion.

 

I love when people start comparing desktop and mobile cards. It turns into a complete migraine.

 

No, starting with the 8x00 series all have been DX10+ cards.

 

First I didn't say 5870M equals to a desktop GTX260, I said they are comparable in terms of performance.

Second, 5870M is based on desktop 5770(with slower clocks, not your so claimed 5750), which is in the same league of a desktop GTX260.

 

Mobile GPUs are desktop GPUs.

 

^^ I guess you have missed something.. Mobile GPUs are not the Desktop GPUs..

 

Yes, mobile cards are desktop GPU's. They're all the same inside, it's just that the ones that come out of a batch as needing less power are destined to go into laptops and the higher power ones will go into desktops. Besides that, they run at slightly different clock speeds and also have more agressive power saving features. Besides that they're as good as identical.

 

ummm thst sir is complitly wrong...

 

It is true to the high-end ones.

5850M/5870M - Underclocked HD 5770. Uses the same die but due to lower voltage, the mobility GPU's are underclocked. Both the desktop and laptop uses the same 800 Shader Processors, 16 ROP's and 128-bit VRAM Bandwidth.

6970M - Underclocked HD 6850. Same idea. Same 960 Shader Processors, 32 ROP's and 256-bit VRAM Bandwidth.

6990M - Underclocked HD 6870. Same idea. Same 1120 Shader Processors, 32 ROP's aand 256-bit VRAM Bandwidth.

GTX 580M - Severely Underclocked GTX 560 Ti. Same 384 CUDA Cores, ROP's and 256-bit VRAM Bandwidth.

GTX 460M/560M - Underclocked GTX 550 Ti. Same 192 CUDA Cores, ROP's and a bit variable VRAM Bandwidth (mostly 192-bit).

Need anymore examples???

 

The 6770m is technically "more powerful" than the gtx 260m because it can deliver almost the same performance at a much lower 30-50 watt TDP.

Therefore if you were to use a 6770m in a cooling system designed for the gtx 260m, your overclocking headroom would be huge. When overclocked the card would be miles ahead of the gtx 260m.

 

exactly my point

 

Mobile GPUs are the same technology than desktop GPUs. What you wronfully are refering to as "different" is merely the names they use for their mobile parts.

Names and technology are very different things.

 

Pardon me, I meant not DX11.

I don't understand why people are still arguing about this. The numbers are there, the information is concrete...

 

We get bored you can tell... (Seriously though, I do agree about your point).
