No matter how many cores you have, there are also the ROPs and more to consider. As you spread a task among more and more threads, it gets more and more difficult to not only utilize them well with complex tasks, but with a GPU, the cores aren't the only aspect of performance even within the hardware to worry about. That gives a more detailed explanation of it. If it matters, these are the specs for the 555m, with the one in the Lenovo bolded:ฤก44 cores 709MHz (GF106), 128Bit GDDR5, e.g. I honestly don't know a lot about computers could you do your best to explain this in a "simpler" way? The same is much less true for embarrassingly parallel compute tasks, but it is nearly unavoidable with gaming performance. This phenomenon's exponential nature means that low shader counts can scale better than higher ones (going from 512 to 1024 scales better than going from 1024 to 2048), so low end GPUs have this effect minimized in comparison to higher end GPUs, but they still don't scale from shader count increases quite as well as from sheer clock frequency increases. The 7950's shader count advantage is much higher than the 7870's clock frequency advantage and the 7950 even has a substantial memory bandwidth advantage, yet the 7950 is not noticeably faster than the 7870. This is why the 1280 shader Radeon 7870 at 1GHz can just about match the 1792 shader Radeon 7950 that's at 80MHz. Clock frequencies scale up performance almost perfectly all of the time unless the memory bandwidth hold the GPU back. As shader count increases, performance scaling form that shader count drops exponentially because there are limits to how parallel a job can be run. Sorry, but shaders do not matter more than clocks for GPUs. You will really notice the issue if you compare it to any decent desktop monitor. This will change depending on how you tilt the screen. You should notice the issue right away that black isn't dark, and actually appears as a grayish, purple-ish, or bluish gradient from the top to the bottom of the screen- sometimes with a quick "dark point" after which it starts getting lighter again. Go find a 15.6" 1366x768 laptop, and display a dark image on the screen. Http /But one of the biggest issues with 15.6" 1366x768 displays, even if you don't notice how little they allow you to fit onscreen, is that they generally cannot properly reproduce dark colors since they tend to be cheap low-tier LCD panels. Any perceived slowness during basic usage will be due to the hard drive speed, and can generally only be remedied by installing an SSD.

And for basic usage (multitasking, movie watching, MS Office, email, web browsing, etc.), it makes essentially no difference what type of processor you have. Gaming is bottlencked by the GPU far before it matters what type of CPU you have, especially when you have a lower-midrange GPU such as the ones in question here. However, it should be one of the least of your concerns which type of processor you get.
The ASUS N53SM-AS51 includes a Core i5 processor, not a Core i7. Therefore, the price difference is actually less than it appears to be. Buying from Newegg does not incur sales tax charges, but buying from does. The Lenovo's GPU does have faster memory though.
The Y570's GPU tends to benchmark closer to a GT 630M than to a 'true' GT 555M. The GT 630M and the Y570's GT 555M both have 96 Shaders, and both receive lower benchmark scores than the 'true' GT 555M with 144 lower-clocked shaders does. Since version of the GT 555M included with the Y570 is actually a misbranded higher-clocked GT 540M / GT 630M, the GT 630M GPU in this ASUS is actually somewhat similar.
