It is unclear from Intel's website if such a driver will be provided in the future. Some systems based on this chipset such as the Panisonic Toughbook U1 http://www.panasonic.com/business/toughbook/ultramobile-rugged-computers.asp are advertised as supporting Windows Vista but do not specify Windows Aero support.  —Preceding unsigned comment added by 76.121.138.71 (talk) 23:10, 19 October 2008 (UTC)

message: Why does the chart list the X3000 as being able to do OpenGL 2.0? According to the documentation on Intel's site, it does only hardware-accelerated 1.5. Is the 2.0 stuff done in software? If so, we should note this on the chart. --Peter 19:16, 21 January 2007 (UTC)

text: Dave, do you know if the 950's shader support also worked on the 900's then? It's certainly possible Intel wouldn't back port, but given that it was all running on the host CPU, it seems equally possible they could have. Maury 13:25, 3 September 2006 (UTC)
replies: text: It's certainly possible, the 900 and 950 have similar enough cores. I think Intel's concern was that you'd need a dual-core CPU to get useful performance figures from software SM3.0 code (though it would still be nowhere near fast enough for any game), and since there's no way to modify 915G to support a dual-core processor, they just didn't see the point in allowing it to support SM3.0. --DaveJB 13:22, 8 September 2006 (UTC)

replies: text: This particular Inquirer article fails the smell test, and has problems to boot.  There's just no way the silicon of the X3000 would implement the same funcationality as the 950 in a less performant fashion, it's based on the same design.  The Inquirer's MO is to shoot from the hip, and sometimes they just plain miss. Be circumspect in using them as an external source, they're very much in the press world of calling things early, right or wrong, which is fine.

message: The article claims that "the GMA series uses tile based rendering, which aims to ensure that only pixels that will end up on-screen will flow through the rendering pipeline."

Tile-based rendering just means that the screen is divided into tiles.

message: I think ther is a mistake here.  It stakes DX9 and unified shader.  We all know that unified shaders need DX10, or shader mdoel 4.0, however this card only supports DX9c and Shader Model 3.0.  In the description of X3000 there is no reference to something exsceptional.
Can someone confirm this is a mistake.  There is nothing about this in intels whitepaper.
http://www.intel.com/products/chipsets/gma3000/gma3000.pdf —Preceding unsigned comment added by Icurafu (talk • contribs) 
:The phrase "unified shader" is used to mean two different things:
:* Under "Hardware: graphics cores: GMA X3000" the article says "... hardware is organized as a unified shader processor consisting of 8 scalar execution units. Each pipeline can process video, vertex, or texture operations."
:* In Windows, the phrase unified shader model refers to the combining of the pixel shader model and the vertex shader model into one thing from DX10 onwards.
:So - in one case the phrase refers to the hardware architecture and doesn't relate to any particular API, and the other is a Windows API thing. Maybe the hardware description should be rewritten to change the phrase "unified shader processor" into something less ambiguous. --Harumphy 09:58, 6 July 2007 (UTC)
replies: text: Xbox 360 uses unified shaders but is not DirectX 10 compliant. DirectX 10 is just a MS API. It has nothing to do with whether the hardware manufacturers can make a bunch of ALUs that can process both vertex and pixel shader code. Considering X3000 has only 8 scalar ALUs, a palty sum with which to do all calculations, I wouldn't expect any sort of decent performance in modern games from it. --Swaaye 20:23, 30 July 2007 (UTC)
thread_title:  GMA X3000 and Unified Shaders 

message: To find out what features a video chip really supports, try the 3D demos from Farb Rausch. http://www.farb-rausch.com/productions.php One of interest is the final version of "Candytron". With the current 15.7 drivers for Vista, the 965 Express not only runs that demo with bad geometry errors in two segments, it also has some texture rendering errors that weren't present in the 15.61 drivers, which just had the geometry errors. (Note that "Candytron" is Farb Rausch's only NSFW demo, if you want to check out the demo.) The older 865 chipset (for which driver development ended in 2005) renders the geometry perfectly, though it can't render some of the effects. The 965 Express runs much more complex and GPU stressing demos like Theta, The Popular Demo and Zeitmaschine 100% correct. No other GPU capable of running "Candytron" that I've run it on has exhibited these geometry and texture errors. (The "party" version of "Candytron" has geometry errors, but they're due to the time pressure of writing the demo during a competition and are thus "built in".)  —Preceding unsigned comment added by Bizzybody (talk • contribs) 11:01, 8 December 2007 (UTC)

It's even inconsistent: e.g. G35 product brief 667MHz render clock, whilst p15 datasheet 400MHz render clock. The G45 datasheet p20 mentions 400MHz as well, which is unlikely. Even worse: Intel doesn't share information about how to read render clock speeds e.g. by GPU-Z: http://software.intel.com/en-us/forums/user-community-for-intel-graphics-technology/topic/56443/ 7obias (talk) 09:33, 14 October 2008 (UTC)

message: When I looked through the spec sheets for the GMA 500 to add the technical info to the comparison table, there were some things which were not clear. PowerVR certainly hasn't been eager to disclose details either. The result is that I wasn't entirely sure whether I had interpreted the spec correctly in regard to some of the details. I think these figures are right but I hope others can find other sources. In particular, the number of shaders, the max video memory, and some of the details about VC-1 and AVC accel could use a double-check.
The number I posted for the peak bandwidth is the memory bandwidth of the chipset in general; I've noticed that this seems to be the way some of the other GMA chips' bandwidth specs are cited. The trouble is that not all of that bandwidth need really be available to the IGP- for instance, the GMA X4500 is listed in the table as having 12.8 GB/s peak bandwidth, which is the chipset's memory bandwidth; p.296 of the spec sheet cited as the source says that the IGP can use up to 12.6 GB/s of that. I didn't change the figure in the table because if some of the IGPs are listed with the bandwidth they can really use (which may not be available information for some of these) and others are listed with the chipset bandwidth (which is usually easily accessible info) then it would be comparing apples and oranges. Should we keep the chipset figures and add a note that the IGP bandwidth may be marginally lower?  —Preceding unsigned comment added by Prodicus (talk • contribs) 19:27, 25 August 2008 (UTC)
