Gma 950 Comparison Essay

Intel Graphics Media Accelerator (GMA) 950

► remove

The Intel Graphics Media Accelerator 950 (also known as Intel GMA 950) is an integrated (onboard) graphic chip on the Mobile Intel 945Gx chipset for Intel processors. It is a faster clocked version of the GMA 900 and does not support hardware T&L (Transform & Lightning) calculations (which is required for some games). Compared to the GMA 900 it now supports Shader Model 3.0 (instead of 2.0) and can decode 2 HD Streams simultaneously.

It supports DirectX 9.0 with Shader Model 3.0 (Vertex Shader are calculated in Software - by the CPU) and OpenGL 1.4. Furthermore, the chip is able to accelerate the decoding of MPEG2 videos and supports Motion Compensation (2 HD Streams simultaneously). Modern HD videos in MPEG 4 or VC-1 can not be decoded with the graphics card. 

The GMA 950 is integrated in the following chipsets with different rendering clock rates (that affect the 3D performance):

  • 945GU: 133 MHz (Lakeport for Intel A100 and A110)
  • 945GSE: 166 MHz (for Atom)
  • 945GMS: 166 MHz / 250 MHz (1.05V)
  • 940GML 166 MHz / 200 MHz (1.05V) - Celeron M (ULV)
  • 943GML: 200 MHz
  • 945GM: 250 MHz (Calistoga)
  • 945G, 945GC, 945GZ: 400 MHz (Lakeport)

Using the GMABooster tool, slower variants can be clocked to 400 MHz to increase the 3D performance (use at your own risk, not supported by Intel!).

The GMA 950 can not be described as a graphics card that is sufficient for gamers. Still Intel published a list  of games that will run (not needingly beautiful) on the notebook (list is for the GMA 900). Some old 3D games and especially 2D games should run without problems. The advantage of integrated graphics cards, is that they have a low power consumtion and therefore save battery life. Furthermore, the laptop may stay cooler and more silent than laptops with dedicated graphics cards. For office programs and surfing the performance is more than sufficient.

The newest drivers support Windows Vista with Aero Glass effects and according to some of our readers it should run fluently.

Intel Graphics Media Accelerator (GMA) X3100

Intel Graphics Media Accelerator (GMA) X3100 is an integrated (onboard) graphic chip on a Mobile Intel 965GM (with 500 MHz core speed) and 960GM (400 MHz) chipset (for Merom = Core 2 architecture). It is the successor of GMA 950. Most interesting is the integration of a fully programmable pipeline. Due to the integration of DirectX9 and DirectX 10 features (with drivers later than, HDR and Hardware Transform & Lighning (T&L) - predecessor only had Software T&L - should be ready for Windows Vista Premium (support Aero Glass fully). Respective the data, the peformance should be clearly better than GMA 950.

The 13.5 Watt current consumption is relatively low, because it includes all chipset functions (therefore, this value is not compareable to dedicated graphics cards).

Intel Graphics Media Accelerator (GMA) 500

The Intel Graphics Media Accelerator 500 (also called GMA 500) is a graphics card for embedded products (e.g. MIDs), netbooks and other small mobile devices. It is usually paired with an Intel Atom CPU and designed for video playback tasks (even HD content). The integrated video decoder is able to accelerate MPEG-2, VC-1, and AVC HD videos.

The graphics core is based on a licensed PowerVR SGX core (Power VR SGX535 as in the Apple A4) and is clocked with 100 (UL11L) or 200 MHz (US15L, US15W chipset). The GMA 500 is compatible with DirectX 10.1 and features 4 unified shaders. Still the performance wont be sufficient for playing 3D games.

The chipsets that integrate the GMA 500 (UL11L, US15L, and US15W) support

Types of Papers: Compare/Contrast

To write a compare/contrast essay, you’ll need to make NEW connections and/or express NEW differences between two things.  The key word here…is NEW!

  1. Choose 2 things that could go in the same category, but are also quite different. Good choices might be:
    • Basketball & Football (both sports)
    • Horses & Cats (both animals, but different in many ways)
    • Writing & Singing (both art forms, but different in many ways)
  2. Gather your ideas by writing down characteristics of each thing.  Note the differences and similarities between them.
  3. Ask yourself these important questions before you begin writing your draft:

Does my instructor want me to compare AND contrast, or am I only being asked to do one of those things?

Some instructors prefer that you only write about the differences between two things, while others want you to focus on explaining the similarities as well.  Either way, you'll need to make sure that your thesis statement reflects your instructor's expectations. For example, if I wanted to write about Social Networking sites, I'd need to write different thesis statements depending on my compare/contrast assignment.  

Sample thesis statement for contrast paper:  In terms of social networking sites, Facebook focuses on presenting your daily life to others, whereas MySpace allows you to focus more on demonstrating your personal style.

Sample thesis statement for compare/contrast paper:  While both Facebook and MySpace allow you to meet other users who have similar interests, only MySpace allows you to demonstrate your personal style.       

Are these 2 things similar and/or different, in at least one meaningful way?

If you want to write a successful compare/contrast essay, you'll need to avoid writing about really obvious differences and similarities.  For example:

  • We all know that horses are larger than cats.
  • We also know that basketball teams contain less players than football teams.

Tell us something we don't know (or might not notice)!

It would be better to write about how sensitive both horses and cats are to human needs and emotions.  You could also suggest that though both basketball and football require a lot of teamwork, basketball players are expected to be a lot more versatile than football players.

You don't have to be a genius to write an interesting compare/contrast essay--you just have to look at ordinary things in a new way!

Do I know enough about my topic to write an effective compare/contrast essay?

Unless you're being asked to do some research as part of your compare/contrast project, make sure that you choose 2 things that you feel comfortable discussing, at length.

Your instructor may ask for multiple similarities and differences--make sure you're prepared to write a well-developed, meaningful essay on a topic that you know well before you get started!   

Organizing Your Compare and Contrast Paper

There are two primary ways to organize your compare and contrast paper.

Chunking: placing all of the information for each individual subject in one place (chunk), and then using similarities as transitions.

Here’s a sample outline:

  1. Jane is distinct because…
  2. Jane is similar to Alice in these ways
  3. Alice is distinct because…

Piecing: giving pieces of the information for each individual subject in each paragraph—arranging the information by topic rather than by subject.

Here’s a sample outline:   

  1. Differences and Similarities in Jane and Alice’s appearances
  2. Differences and Similarities in Jane and Alice’s backgrounds
  3. Differences and Similarities in Jane and Alice’s interests
