I would love a 640m vs 6750m/6770m 1GB writeup. My MBP gives great performance and i would love to know where my 6750m stands against the new kelper mobile card's.

640m wins by about 25%

oh wait you got the 6750m, the castrated apple version.. then its more like atleast 50 to 60 %

[downloads]

25% seems like a stretch to me.

Using notebookcheck's game benchmarks.

Star Wars: The Old Republic (high)
6770- 40fps
640M-33fps

The Elder Scrolls V: Skyrim (high)
6770- 30fps
640M-31fps

Battlefield 3 (high)
6770- 22fps
640M- 26fps

Crysis 2 (high)
6770- 40fps
640M- 40fps

There are games that favor 640M in F1 2011 640M wins (51 vs 27) and Deus Ex HR (61 vs 42) but most are very close.

Overall 640M is the winner since it either draws with 6770 or wins but I wouldn't go for an average 25% increase as more like double or nothing

downloads, there is a huge thing that slipped your eyes. That is, the GT 640M is tested with a Sandy Bridge ULV 17W CPU. If paired with the quads the GT 640M will definitely be around 20% to 30% better than the 7690M/6750M.

Also the comparison is on 6750M vs GT640M, not on 6770M vs GT 640M.

Either way GT 640M is a milestone for those who want a powerful discrete GPU in a thin form factor.

Yeah- that may be the case. I'm not saying 640M is bad though- to the contrary.
Last series of mid-range cards from both AMD and nVidia was useless. This time nVidia did good which hopefully will force AMD to work harder too.

I have nothing against being wrong as long as I'm underestimating those cards.

[yknyong1]

Not saying you are wrong. What you provided is a M3 GT 640M benchmark against current gen 6770M notebooks, which is really relevant to the thread. Just clarifying some parts which may not be clear to some of us when dissecting the information.

Actually, I think the Sony Z11, the Acer 3820TG and the LG P330 were more groundbreaking designs for their time, but I do like the new Timeline U and I think Acer will price it right. This is likely to be the best option for someone wanting a lot of GPU power for ~ $800 USD. The low power CPU is probably a decent compromise to prevent the CPU from throttling since it is clear that cooling systems like the 3820TG are too expensive for Acer. I like the idea of the self OC'ing Kepler GPU. Hopefully, the automatic OC'ing does not interfere with conventional OC'ing.

It is a shame that Acer discontinued the 13.3" display model of the Timeline U series in favor of its S5 ultrabooks. I think 13.3" is the sweet-spot if you are going to use an HD display.

I totally agree with you.. I just recently got the p330 and im quite satisfied, but I would wish the display is an IPS-Display as promised at computex at first..

But I do think that sooner or later there will be some 13.3 inch notebooks with atleast the 640m, there is already (suspected) a sager 11.6 inch with a 650m..

But I love the build quality of the p330, so I will probably just keep it and maybe consider Maxwell (Generation after Kepler), since the 650m perfomance can nearly be reached by overclocking and the difference isnt that great

BTW: I have owned the 3820TG too, but the build quality of the p330 is miles ahead.. But I loved the dual cooler of the 3820TG.. Currently only the 2442 from gigabyte (IVB + 640m kepler) seems to have dual coolers, but very very cheap build quality)

How much faster is the nvidia 640M compared to the Radeon HD 6550M installed on my 4820TG ?

About 50-60% depending on game?

[ZeroCell]

Hmm, so if the main problems are the screen and power button placement, would it be worth waiting for Gigbyte's upcoming ultrabook?

Also has a 640m, but includes a higher-res screen, seemingly sturdier construction, backlit keys, traditional port placement, and Ivy Bridge.

Having trouble seeing the Acer's advantage right now, aside from being released sooner and costing probably around $200 less.
