Y570 GT 555m question

Is the GT 555m on Y570 the legit and true GT 555m like the one on m14x?

Reason I asked because I see post from Y570 owners that it is 128 bit instead of the real 192 bit.

Can any of the Y570 owners please clear this up.


Thanks

 

There is no true GT 555M personally I prefer the GT 555M with GDDR5 and the price on the Y570 also makes it a very attractive package.

GeForce GT 555M

 

its not legit like the one on m14x, it is just a oced 540m. expect 1k-2k less in 3dmark06

 

OC'd 540m? What?

 

Since it's looking like it's the regular DDR3 version, you'd probably be much better off getting the Sager NP5165.
Sager NP5165

Same GPU, but the screen is actually decent (read: 1366x768 is not good for a 15.6" screen, but 1920x1080 is really good)

 

This is where Lenovo really drops the ball IMO. I would pay a good amount of money if they would at least have the option for a higher res. screen. Not to mention the current one lacks contrast and has awful viewing angles. The w520 has it, why can't the y570/y560p?

 

That, AND the Sager NP5165 offers an upgrade to the 95% gamut matte LCD, which is the exact same 1080p screen used in the W520. The AUO B156HW01 V4.

Also note that the Y460 is supposed to have a dual-channel LVDS cable, so a 1600x900 display upgrade should be possible to do yourself. Just make sure you get an LG screen, because LG is afaik the only one that makes decent 14" 1600x900 screens.

 

I've heard the 555m is crippled in the lenovos...not sure what that is about though

 

There are 2 GT555M, one based on the GF106 core (DDR3 RAM) and one based off the GF108 core (GDDR5 RAM). However the DDR3 one has WAY more shaders, TMU and render output units. Crippling GPU's I haven't officially heard of on Lenovo's but it maybe to keep power draw at a certain level. Also IdeaPads already offer a decent spec laptops at a decent price. Adding an FHD screen or an HD+ screen would jump it into next price tier where consumers aren't normally going to pay for an IdeaPad.

 

From some quick price searching, the average FHD LCD costs about $70 more than the average HD LCD. Bump that up to $99 so Lenovo makes money off of it, and it's not too much of a price increase. I think most people would pay it (the educated ones who knew what the upgrade means)

 

Sure, I condone low screen resolutions but given what I've seen working 2.5 years in retail, people want the cheapest laptop they can get their hands on. The average consumer would rather get that processor or RAM upgrade before screen resolution. Processor and RAM = near pure profit for manufacturers, while screen resolution results in less profit. Remember companies exist to make money not sell products. Also retail stores only carry a limited selection to begin with, and Lenovo is typically the smallest major brand in most stores.

 

There are 3 555m GTs that I know of in the wild. Nvidia only listed two for some reason.

The ones in the Dell XPS 17/m14x is the DDR3 with the 144 pipelines and 192-bit bus width (best version).

There's a 555m GT GDDR5 with only 96 pipelines and 128-bit bus (higher than the above, but the low pipelines REALLY kills its performance) as in the Lenovo Y570.

Then there's the almost "fake" 555m GT with GDDR3 and only a 128-bit bus width (Sager NP8165). But if this one has 144 pipelines, it'd still be better than the 555m GT with GDDR5... but with 96 that'd be absolutely pathetic (glorified 525m at best).

 

I'd definitely pay $100 more for less eyestrain and scrolling for a device I will be using for hours on a daily basis. Shame that the 'average user' doesn't think that way in the things that are really worth investing into. Oh wait, Sager does that price for the 95% CG screen!

 

It has 144 pipelines. It's fine. In ways it's better than the one in the Lenovo.
