What are the specs of the X2300? How much better will it be than the X1700 and the Go7700? I googled it and searched the ATI website and didn't find anything.

Perhaps instead of a better graphics card, the option for a 9 cell battery on the A8J series. Oh and something other than crappy plastics.

I am PRETTY sure that the x2300 is just going to be the replacement for the x1300 and/or the x1400 GPU. The big difference is that it is based on the R600 so it is a DX10 mobile card.

I see. So I'm going to want to wait until they start coming out with the X2600/X2700 if I want the real next big step. Which leads me to believe that Nvidea would be coming out with their DX10 version...maybe the Go8600/8700? Nothing to do but wait...wait...wait...

Aww man!, the X2300 isn't an upgrade from the X1800/1900 at all.
It looks like a watered down, energy efficient, hybrid to the X1800.
They're actually identical in all but the following specs:
(X1900 first spec, X2300 second spec)
312 million transistors - 105 million transistors
36 Pixel Shader Processors - 4 Pixel Shader Processors
8 Vertex Shader Processors - 2 Vertex Shader Processors
256-bit 8-channel DDR1/DDR2/GDDR3 memory interface - 128-bit 4-channel DDR1/DDR2/GDDR3 mem...
Up to 384 simultaneous pixel threads - Up to 128 simultaneous pixel threads
Not DX10 compatible - Not DX10 compatible (VISTA compatible yes, DX10 no!)

So with the X2300, you get greatly improved battery life, but a technically inferior product to the X1800/X1900.

That kinda sucks.

Just a note to all people about ATI and NVidia card naming process, to help distinguish how "powerful" a card might be. Their numbering system is broken down as such:

XYYY where X = the generation and YYY - the series

As we all know, cards go through generations. For ATI originally we had the 100 cards, which technically were 0100 (first generation). We then moved onto 1000 (generation 2) and now we're moving up to 2000's (generation 3). This is more a difference in technology (ie 0100 cards were DX8, 1000's were DX9, and 2000's are going to DX10).

The actual POWER of the card, is signified by the series number, no the generation number. So the higher the series number, the more "powerful" the card. For example, a 1600 series card is going to be a lot more powerful than a 2300 series card, from a performance standpoint. You'll get better frame rates, etc.

If you have a choice between a 1600 card and a 2600 card, take the 2600 because you get same performance (600 series) but a newer genration (DX 10 vs DX9). But if you're looking for higher frame rates, take a 1600 over a 2300. Hope this helps.

Almost but not quite Frubles.

You got it right that the x2300 will be slower than an x1600, but, your comparison of the "equivalences" between next and current gen is not quite correct. The next generation with the equivalent is always faster than the last generation. Otherwise based on your logic, the Geforce 6600 would be just as fast as the 7600 and the Radeon x600 the same speed as the x1600, which we simply know is not true. New features are only part of the new generation of cards. If there was no improved performance, then there would be no incentive to upgrade.

X2300 is not a DX10 card.
