In the field of 3D computer graphics, the unified shader model (known in Direct3D 10 as "Shader Model 4.0") refers to a form of shader hardware in a graphical processing unit (GPU) where all of the shader stages in the rendering pipeline (geometry, vertex, pixel, etc.) have the same capabilities. They can all read textures and buffers, and they use instruction sets that are almost identical.[1]
Earlier GPUs generally included two types of shader hardware, with the vertex shaders having considerably more instructions than the simpler pixel shaders. This lowered the cost of implementation of the GPU as a whole, and allowed more shaders in total on a single unit. This was at the cost of making the system less flexible, and sometimes leaving one set of shaders idle if the workload used one more than the other. As improvements in fabrication continued, this distinction became less useful. ATI Technologies introduced a unified architecture on the hardware they developed for the Xbox 360. Nvidia quickly followed with their Tesla design. AMD introduced a unified shader in card form two years later in the TeraScale line. The concept has been universal since then.
Early shader abstractions (such as Shader Model 1.x) used very different instruction sets for vertex and pixel shaders, with vertex shaders having much more flexible instruction set. Later shader models (such as Shader Model 2.x and 3.0) reduced the differences, approaching unified shader model. Even in the unified model the instruction set may not be completely the same between different shader types; different shader stages may have a few distinctions. Fragment/pixel shaders can compute implicit texture coordinate gradients, while geometry shaders can emit rendering primitives.[1]
Unified shader architecture (or unified shading architecture) is a hardware design by which all shader processing units of a piece of graphics hardware are capable of handling any type of shading tasks. Most often Unified Shading Architecture hardware is composed of an array of computing units and some form of dynamic scheduling/load balancing system that ensures that all of the computational units are kept working as often as possible.
Unified shader architecture allows more flexible use of the graphics rendering hardware.[2] For example, in a situation with a heavy geometry workload the system could allocate most computing units to run vertex and geometry shaders. In cases with less vertex workload and heavy pixel load, more computing units could be allocated to run pixel shaders.
While unified shader architecture hardware and unified shader model programming interfaces are not a requirement for each other, a unified architecture is most sensible when designing hardware intended to support an API offering a unified shader model.
OpenGL 3.3 (which offers a unified shader model) can still be implemented on hardware that does not have unified shader architecture. Similarly, hardware that supported non unified shader model APIs could be based on a unified shader architecture, as is the case with Xenos graphics chip in Xbox 360, for example.
The unified shader architecture was introduced with the Nvidia GeForce 8 series, ATI Radeon HD 2000 series, S3 Chrome 400, Intel GMA X3000 series, Xbox 360's GPU, Qualcomm Adreno 200 series, Mali Midgard, PowerVR SGX GPUs and is used in all subsequent series.
The High Level Shading Language for DirectX implements a series of shader models. Using HLSL, you can create C-like programmable shaders for the Direct3D pipeline. Each shader model builds on the capabilities of the model before it, implementing more functionality with fewer restrictions.
Shader model 1 started with DirectX 8 and included assembly level and C-like instructions. This model has many limitations caused by early programmable shader hardware. Shader model 2 and 3 greatly expanded on the number of instructions, and constants shaders could use. They are much more powerful than shader model 1, but still carry some of the existing limitations of the first shader model.
Starting with Windows Vista, shader model 4 is a complete redesign. It allows unlimited instructions and constants (within hardware constraints of your machine), has templated objects to make texture sampling cleaner and more efficient, and has the fewest restrictions of any shader model. It does however require the Windows Driver Model which is only available on the Windows Vista (or later) operating system.
Shader Model 5 is a superset of the capabilites in Shader Model 4. It has been designed using a common-shader core which provides a common set of features to all programmable shaders, which are only programmable using HLSL.
I don t know what version is on my notebook because of this I detailed all the components on it ,probably is intel hd graphics 2000 or 3000, please tell me if it supports pixel shader 3 this model or if they are new drivers to improve the performance for this model.I want to know what games can I play with this laptop and if it is a list made for my model processor.I want to know if I can play Counter Strike Global Offensive, Call of Duty: Modern Warfare 2 and 3, Battlefield: Bad Company, Street Fighter IV and others.
I have downloaded the latest drivers for intel hd graphics i3 version 8.15.10.2993 but shaders 3.0 aren't still supported. I checked it by GPU caps viewer and it shows that supported just 2.0 not over
glclal, I am sorry about the trouble, I have confirmed through engineering that once you install the latest video drivers, shader model is available with version 4, please take a look at some specifications here:
Ol boa tarde! Algum poderia me ajudar? Estava fuando os programas pelo painel de controle do note para desinstalar algum programa que possvelmente estivesse muito pesado e acabei desinstalando o gpu shader 3.0. Agora meu jogo Pes 2012 no roda mais. Como posso reinstalar este programa?

DXTweaker aka DirectX Tweaker spoofs values but apps/games do some additional checks and do not detect shaders 3.0. By the way, it only exists as time bombed beta and you need to set date in VM to somewhere in 2005 to get it working if you want to try its tweaks.
You can use #pragma directives to indicate that a shaderA program that runs on the GPU. More info
See in Glossary requires certain GPU features. At runtime, Unity uses this information to determine whether a shader program is compatible with the current hardware.
You can specify individual GPU features with the #pragma require directive, or specify a shader model with the #pragma target directive. A shader model is a shorthand for a group of GPU features; internally, it is the same as a #pragma require directive with the same list of features.
It is important to correctly describe the GPU features that your shader requires. If your shader uses features that are not included in the list of requirements, this can result in either compile time errors, or in devices failing to support shaders at runtime.
If the list of requirements (or the equivalent target value) does not already include these values, Unity displays a warning message when it compiles the shader, to indicate that it has added these requirements. To avoid seeing this warning message, explicitly add the requirements or use an appropriate target value in your code.
You can also use the #pragma require directive followed by a colon and a list of space-delimited shader keywords. This means that the requirement applies only to variants that are used when any of the given keywords are enabled.
You can also use the #pragma target directive followed by a list of space-delimited shader keywords. This means that the requirement applies only to variants that are used when any of the given keywords are enabled.
The HLSL shader model is a versioning approach indicating which new features are added to the language. Each level allows an application or game to target a well-known set of functionality for development, and allows hardware and driver developers to target that same description for support.
In order to build shaders for Windows Store apps (and Windows Phone 8) Shader model 4_0_level_9_3 you need to use the vs_4_0_level_9_3 and ps_4_0_level_9_3 . While all this sounds fine using the HLSL syntax designed for DirectX 10 and up, I'm unable to use the VPOS semantic from DirectX 9 or use SV_POSITION from DirectX 10 and up in a pixel shader, so what do I do besides making yet another semantic for outputting the vertex position in clip space ?
PS: Some shaders on 4_0_level_9_3 spit out an "internal error: blob content mismatch between level9 and d3d10 shader" which I have no idea what is about. Probably some inconsistency with the driver I suppose ( I use an Nvidia GTX 560 TI) that I see it goes away if you just compile your shaders with release flags (like optimization level 3 and avoid flow control).
Your best bet is, as you say, to pass these values as secondary semantics (i.e. pass both a "POSITION" and a "SV_POSITION" value). Note that if you place SV_POSITION at the end of the output declaration for the vertex shader, you may omit it from the input declaration for the pixel shader.
Regarding the internal error, this is typically due to the declaration of a texture or other shader input that is optimized out in one pass but not in another. Disabling optimization typically works around the issue, but you should also be able to fix it by eliminating unused (including via dead-code elimination) input declarations, and ensuring you avoid complicated code that reduces to no-op.
