also @ TechSpot: Intel says Haswell will improve battery life by 50 percent
AMD traditionally launches new graphics products with high-end models on the desktop and then works its way down and into laptops. This time, they are doing the exact opposite by launching the Radeon HD 7000 family on the mobile side first with the entry-level and midrange 7400M-, 7500M-, and 7600M-series. There's a reason for that, however, as it seems AMD is just making time for real next-gen Radeons to arrive.
The new GPUs are not based on the 28nm production process developed by TSMC as we'd expected. Instead, the chips employ the same 40nm Turks and Caicos GPUs that currently power the 6000M series. They're likely getting some tweaks here and there to improve performance, such as increasing the shader count and slightly boosting clock speeds compared to the 6000M parts they’re replacing.
AMD hasn't revealed the actual models that are launching but provided some specifics for each series:
|
Radeon HD 7400M series |
Radeon HD 7500M series |
Radeon HD 7600M series |
|
| Segment | Value | Mainstream | Performance-Thin |
| Process | 40nm | 40nm | 40nm |
| Memory type | DDR3/GDDR5 | DDR3/GDDR5 | DDR3/GDDR5 |
| Memory Bus Width | 64-bit | 64-bit | 128-bit |
| Stream Processors | 160 | 480 | 480 |
| Eyefinity Support | Up to 4 monitors | Up to 4 monitors | Up to 6 monitors |
All three GPU families also feature DisplayPort 1.2 and HDMI 1.4a connectivity, as well as support for DirectX 11, AMD HD3D and Blu-ray 3D. Compared to their Radeon HD 6000M counterparts, we note that the 7500M has 80 more stream processors than the 6500M, but there's not much to tell beyond that at this point.
The launch of 28nm graphics products from AMD will happen soon enough, according to reports. Last we heard, AMD's "Southern Islands" architecture was scheduled to arrive by the end of this year, but with TSMC having issues with 28nm production, those plans have been apparently delayed until early 2012.

Anand has an article on it, and also with a table showing the original names. [link]
Products renaming at it's finest!

Isn't Nvidia doing this also with Kepler? starting with the lowest models and making its way up to the high end models? Wonder why both have decided to change and do it this way?

Yea, see the link I posted above, nVidia is doing the same thing.
I guess it's easier to just rename your old shit than actually make something new eh?

There is no truth in advertising when it comes to mobile GPU's.
These rebrands, just like the last round (continued here) are at the behest of the OEM's. Pretty hard to shift new stock for the holiday season if it doesn't boast higher model numbers that the same stuff thats been available all year.
Yo Ho Ho, and a Merry Christmas to the uninitiated from Dell, HP, Acer, Toshiba....

The comment about mobile GPU's is so true, and funny.
I remember last year a friend of mine was bragging about his 5870M in his laptop and how well it ran games at 1080P, but how he didn't like his 5770.
Then he found out a 5870M's specs are nearly identical to a 5770.

Yeah my GTX 260M is technically a GeForce 9800 GT 1GB but in a laptop.
