Asus ROG G55 & G75 in April with gtx 670m

Remember however that the second digit such as the 6 in 560m also plays a HUGE part in performance. For example, although the 485m is a generation "behind," it is still ridiculously fast. (The 485m is approx. equivalent to a 570m, give or take a percent)

Very true. The second digit is also very important in determining the performance of AMD's GPUs, although I would say that AMD's numbering system is even more confusing than Nvidia's.

That's surprising the older GTX 485M is about equal to the 570M. I always thought that it was about as fast as the 580M considering that it's based off the desktop GTX 460 1GB but with more CUDA cores and lower clocks.

The 485M is 15 to 20 percent faster than the 570M.

More cores, more ROPs, and more bandwidth, while they have the same exact clocks.

Yeah sounds about right. I remember the GTX 485M used to be top-of-the-line, occupying the same spot as the 580M now.

Hopefully Asus is finally doing actual high-end gaming laptops again. Haven't really seen that in about 2 years.

Speculating is fun when news is slow. We probably won't find out what's what for at least another month, so why not guess at what will be revealed?

And how is my logic trolling?

It will likely have:

1. More shaders than the 570M
2. Higher clocks than the 570M

My conclusion is simple: Today, an overclocked 570M matches the stock 580M. If my numbers one and two are correct, that makes the 670M like an overclocked 570M, but with even more shader and architectural improvements. How then does it not equal the 580M?

I believe my projections are accurate, but will eat my portion of crow if I'm off base.

ok...but a 560m overclocked matches a stock 570m?

No, it doesn't.

No, it doesn't.

Sarge is correct. The 570m has 336 pipelines while the 560m has only 192. Overclocking will close the gap slightly, but the 570m will still greatly outperform the 560m. (Even then, the 570m can be overclocked as well)

The 460m and 560m are both based on the same architecture and the same pipes; the only difference is clocks and power usage. The 560m though can overclock higher more safely. (reliably)

Edit: I really wish they still sold laptops with the 485m. They would now be cheaper with the release of two new generations (the 6xx generation will be soon), while still giving amazing performance.

I'm not here to suck up but I totally agree with Kevin, GTX 670M = GTX 580M (-10%).

The GTX 670M will be 70 watts which = 100W 500M series and will be 30% faster than the card it is replacing GTX 470M which equals GTX 580M (-10%).

I was thinking of getting a Qosmio X775 with GTX 560M but I think I'll be waiting for Qosmio Ivy with a 600M series card which most likely be GTX 470M same as the ASUS but I prefer a lighter laptop so heavier gaming laptops like ASUS, MSI and Sager does not appeal to me.

[Ayemageyene]

I'm not worried about the weight as I would be about the sound of the fans and cooling.

Unless G55/G75 come with GTX 675M, we will not see a big improvement in the the GPU performance. It will be like the transition from 460M to 560M (minimal)



But, it's improvement nonetheless.
