500 point 3dmark difference in 510pvs500

How big is this difference? How noticeable is it? Is it worth upgrading from a 500?

 

How big?

Imagine you are watching 100 ants in a cage. And compare that with watching 110 ants in a cage.

 

... ? What an odd response.
Though OP if you had just done some google searches this would have been answered for you a million times over. I mean, the info you're looking for is on the FIRST page of this forum. Search!

The only difference from the LATEST Y500 (with 750m's) and the Y510p's are the 4th generation Haswell CPU and Battery life (& POSSIBLY the activation of the iGPU through Optimus). If these things appeal to you, buy the Y510p.

If those features don't matter to you, or you'd like to save some money and go with the 650m's, you should do so, as all the upgrades from Y500 rev1 (650m) --> Y500 rev2 (750m) --> Y510p (Haswell+750m) have been incremental at best and not worth it if you can find great deals on one of the Y500 models.

Tradeoffs:
Y510p - more heat, 5% CPU performance increase from rev1/2
Y500 rev2 - %10-15 GPU performance increase from rev1
Y500 rev1 - slightly slower though puts out the least amount of heat (for GPU's).

 

If I was in the market for a new laptop then I would definitely pick the Y510p over the other two. I mean, why not? The Y500 is a solid performer regardless, and I've had this thing since the beginning of December last year. My decision was whether to get the Y500 or the Y580 back then, of course the Y500 is superior and with SLI, it absolutely destroys everything within it's price range. But 6 months later, the Y500 is obsolete in the eyes of Lenovo and the new kid on the block is the Y510p. Get the Y510p. Just be warned that Lenovo is a joke of a company and hope that they fixed the issues that plagued the Y500. As long as you know what you are getting yourself into, it's all good.

 

Performance wise, seems the Y510p is a heck of a lot faster than the Y500s in 3DMark11. Don't know how that translate into real life. As far as comparing the Y500s, there are almost no difference between them. The 750m is nothing more than a relabeled 650m running on higher voltage and clock. The newer Y500s are able to overclock the video memory higher but as far as the core, there is no difference. I can run my core at about as high as 90% of the 750m's out there but with the way it heats up the laptop, I rather run it at stock voltage and at 1155/2555 SLI. That's my comfortable overclock, rock solid and everything stays relatively cool and something I've been doing since December of last year. Which is still way faster than a Y500 w/ 750m and pretty comparable to a stock Y510p and I've been enjoying this kind of performance for the last 6 months, long before you guys knew what a Y500 was.
