More G9x cores but GDDR5 could make a difference as could clocks.

At this point I would like to say I am getting back into the notebook scene, more on that when I get everything

 

I've been wanting to get a new notebook. Really want something with a 260M. Know of any? I know sager has one. Was hoping for something a little cheaper. Hopefully gateway will update their FX series at Best Buy with one.

 

no gateway won't more then likely they would put a gts 260 in it

 

there is the spec sheet

these are not 9 series rebrands btw

 

check out the speed on that ddr5

 

The Asus G51 will be out next month. The press releases cite a GTX 260M for the graphics card.

 

gtx 260 and gtx 280 are still faster

 

The GTS 250M looks pretty much exactly like a 40nm 8800M GTX (96 shader cores, 500/1250/1600) (with the GDDR5 making up for only being 128-bit). So it should offer the same performance, but with a much smaller size and TDP. That is pretty awesome.

 

About time Nvidia fixed their 40nm manufacturing issues, now to see if their new chips can challenge their ATi equivalents on the mobile front.

 

the 4860 is the competitor with the GTS 260

 

Most of the head-to-head competitions can probably be established by looking at the specifications, I'm more interested to see what competing benchmarks will throw up once the new chipsets are properly released on the mobile market.

 

If the GTS 260M is going to be under the GTX 260M then the 4830 would be the closest competitor to the GTS 260M.

 

maximum pc

 

4860 wins in my book dual outputs is quite nice
was released first to

 

Was released first? You mean the tech specs were released first, and I haven't seen either in a notebook you can buy right now, so none of us know anything!

 

So does the GDDR5 Memory Clock being twice that of GDDR3 compensate for half the Memory Bus Width?

 

Wow, those power usage are very impressive. A pair of 250M/260M GTS will use similar amount of power as single 280m GTX

 

Yep, pretty much exactly.

 

yes exactly, apart from lower tdp.
very interesting.

 

Well, it was already tested in an Asus K51AB, and is around 10% faster compared to the mobility 4850. I'm guessing it's delayed because either Asus or ATi wanted to release it with AMD's new notebook platform, which should be released around this time actually.

As for these new cards for nVidia, congrats. Let's see what they do with the Quadro mobile series

 

well they have quoted effective speed as gddr3 which is confusing.
gddr5, is quad data rate, 900mhz gddr5 is equilalent to 1800mhz gddr3. so 900mhz 128bit gddr5 would have the same bandwidth as 900mhz gddr3 256bit.

 

My guess is the delay in the 40-nm Mobility 4800 cards is because of bad manufacturing yields from TSMC.

We'll know for sure if that's the case if Nvidia's 40-nm cards also take forever to show up since TSMC is manufacturing them as well.

 

If that is the case, then the GTS 250M looks mighty nice to me. I wonder when we will start seeing notebooks with them? The low TDP looks like it will allow a pretty awesome gaming laptop with a pretty good battery life. What do you think the chances are of HP/ASUS/Gateway/Sager picking these up?

 

My guess is the 4860 simply wasn't achieving the results it should have (clearly better than the 4850).

Comparing 4770 to 4850, the 4850 clearly stomps it at higher resolutions. I don't understand all the fuss about having 128 bit cards with GDDR5 and expecting high end performance. The best part is of course the lower wattage and great power/performance ratio.

 

dont forget price vs power !!!!!!

 

Yeah the 128bit GGDDR5 GPUs aren't performance beasts, but really the most interesting point is the ability to pull less power for good performance. They would make decent middle grounds for those who want decent performance and decent battery life for example.

Interesting note, I'll be looking forward to seeing the benchmarks for that GTS250M in comparison to the HD4830/HD4860

 

i love the feature from the 4860 with dual out puts and can run @ like 2500 res

the dvd upconverting is nice to

 

Well, being that the GTS 250M only draws 28W (which is only 5W more than the GT 1xxM/96xxM series) it should have comparible battery life to notebooks with the GT 1xxM/96xxM series graphics cards (possibly up to 3-4 hours per charge on a 6-cell battery).

The memory bandwidth should be equivalent to that of the 8800M GTX / 9800M GT even though it only has a 128-bit bus (Memory Bandwidth = Bus Width * Memory Clock * Data Rate [GDDR3 = Double Data Rate, GDDR5 = Quad Date Rate] [8800M GTX/9800M GT Memory Bandwidth = 256 * 800 * 2 = 51.2 GB/s] [GTS 250M = 128 * 800 * 4 = 51.2 GB/s] [GTS 260M = 128 * 900 * 4 = 57.6 GB/s]).

So specs wise, the GTS 250M should be equivalent to the 8800M GTX/9800M GT but with more than half the TDP (better battery life, less cooling needed, etc.) and I would assume it would be cheaper than the GTX 260M since it's not as high performing as it (and uses 40nm manufacturing). The GTS 250M might also be faster than the 8800M GTX/9800M GT due to possible optimizations in firmware/drivers/etc. and the GTS 260M should definately be faster due to its higher clocks. Also, the lower TDP would make it a prime processor to use in SLI and to incorporate in smaller-form-factor notebooks (16" and below).

Or at least that's my take on it.

 

about time they copied ATI, GDDR5 is more innovative, is cheaper, cooler, etc than implementing a 256bit bus, this should be the direction to go from now on.

 

Going backwards is never the right idea. 256 bit and GDDR5 is another story.

 

I was referring to laptops, I dont quite see how reducing heat and power consumption while maintaining the same power output is going backwards?

 

thats called the ATI 4870

ATI always said thats what it was going to be

 

It's a good idea for the mid-range class though.

But yes, 256bit and GDDR5 is beast

 

the 8800m gtx is high end

those are mid - high end cards

 

I agree with you, 128-bit + GDDR5 being able to accomplish the same performance as 256-bit + GDDR3 at lower power consumption and manufacturing cost is definately a step in the right direction, especially for a person like me that doesn't need to have the best of the best, but still want a pretty decent gaming notebook. For the people who need that kind of power, I'm sure 256-bit + GDDR5 is sitting around the corner waiting for the 125W+ 18"+ $3000+ notebooks that they are popular in (no offense, but unless gaming was the only thing I was doing, I don't see any reason I would want one of those). Also, if you were to SLI these, you'd essentially get 256-bit + GDDR5. If the GTS 250M can accomplish 8800M GTX/9800M GT performance or better at that TDP (which theoretically it should given I'm reading the chart correctly), I'll be extremely happy. Personally, I don't really care for the GTS 260M, I'd rather have the 10W less TDP than the 10% more performance, but that's just my personal preference.

 

heck you could have a gaming netbook with that tdp....

can see it now gts 260m in a 12 inch laptop ....playing L4D

 

The 4770 was never meant to beat the 4850. The 4770 replaced the desktop 4830 (different GPU than the Mobility 4830) and placed exactly where it should have performance wise in the hierarchy.

 

love that word ......

 

what's the TDP of the g105m now? i can't seem to find it...

 

Hey all. I need a gaming notebook in 2 months. Should I buy now, or wait for 40nm nVidia cards? Thanks for answers, and good night all!

 

When should we expect these new cards to make their way into some notebooks?

 

Q3 is my guess.... maybe Q4
