New Z500 coming soon according to Hikari85, most probably with gt740m.

Good news from Hikari85:
Current model Y400 & Y500 phase out, new model coming in 1-2 weeks time.

Performance comparison:
gt750m(new Y400) > gtx660m(Y580) > gt650m(gddr5)(old Y400) > gt740m(ddr3)(Z400)=gt650m(ddr3)(N56vz) > gt730m(acer V3)=gt645m(old Z400)

Latest benchmarks from China:

3Dmark11 with core i7, gt750m/Y400=P2937 > gtx660m/Y580=P2636 > gt650m/Y400=P2300.
3Dmark11 gt750m pawn gtx660m.


GT750M core clock OC to 1058mhz.

Ultrabook and most of the traditional notebook also not easy to maintain.

Perhaps, more or less around the same price range of Z500/gt645m.
Stay tune for latest updates.

Lenovo will have some pc fairs promotion, wish they surprise us with new Y500/Y400 & new Z500.
Most probably will be after pc fairs clearance sales.

If you are gamer, wait and grab the upcoming Y500/Y400 +GT750m(GDDR5) which have better performance above GTX660m (ie Y580), much better cooling system, poisoness red backlit, optional swappable ultrabay, removable battery, slot for mSATA SSD and easier self upgrade of HDD, SSD, ram and dust cleaning compare to new Z400.

Else wait to grab new Z500/GT740m around the same performance of GT650m( ie N56vz) with bigger screen and better cooling compare to Z400.

Yes and no.

GT750m > GT650m sli for non sli supported games.
GT750m <,=,> GT650m sli for not very well optimize sli supported games.
GT750m < GT650m sli for well optimize sli supported games.

Generally, performance comparision:
GT650m sli > GT750m > GTX660m > GT650m(GDDR5) > GT650m(DDR3)=GT740M

GT750m sli performance surely awesome if they can scale the performance within the same TDP of GT650m sli due to matured 28nm manufacturing. But I doubt it.

Lenovo new Z500 touch and U410 touch specs with GT750m in their website.
Hopefully no typo in Lenovo site.

Y400/GT750m ETA around 1-2weeks according to Hikari85, Lenovo might suprise us during coming PC fairs.
The old model Y400/GT650m phase out and many places already out of stock.

Best is to check it with Hikari85 or Devour.

Try this:

Lenovo only launch Y500 with GT750m in other country.
No news on GT750m SLI yet.

Yes, it do support sli . They will launch it iff they can manage the TDP well and good demands.

Try to flood local Lenovo facebook and pressure them to bring in faster Y500/FHD/i7/GT750m & Y400/i7 or i5/GT750m like what happens to Y580 reported here: http://www.lowyat.net/2012/08/10/4085/the-...ails-at-rm3599/

Local Lenovo facebook: https://www.facebook.com/LenovoMY

Good luck.

My guess is around the same price or + RM100 compare to old models for Y400 if they only upgrade the gpu.
New Y400/GT750m launched in China around the same price of Y400/GT650m.
Guess Y500 will follow the same basic.

Wish my guess is true.

Its more like clearance sales during PC fairs with old specs & same RRP . Even the promotional brochures shown old spec Z400/GT645m where new Z400/GT740m already available.
My guess is Y400/Y500 + GT750m and Z500/GT740m will come after the clearance sales.

Wow, local Lenovo facebook start to flood with upcoming Y500/Y400+GT750m . Wish the history repeat like whats happen to Y580 : http://www.lowyat.net/2012/08/10/4085/the-...ails-at-rm3599/
