Computer users upgrading to Microsoft Vista may find they need more memory, a faster processor, and more versatility in computer architecture to get their upgrade to operate efficiently and make the Vista upgrade worthwhile. Microsoft's current system requirement recommendation is that your computer have the following:
- Processor with a minimum speed of 1GHz (x86 or x64)
- 1GB of RAM
- A GPU that supports DirectX 9 and the following:
- WDDM (Windows Vista Display Driver Model) Driver
- 128MB of video RAM
- Hardware support for Pixel Shader 2.0 (Pixel Shader 2.0 is a shader program that adds 3D shading and lighting effects to pixels in an image. Microsoft's DirectX and Silicon Graphics' OpenGL support pixel shaders. In OpenGL a pixel shader is called a fragment shader)
- 32 bits per pixel
- 40GB hard drive (with 15GB free - again, don’t worry though, Vista doesn’t take up 15GB, it just needs that much room to install!)
- A DVD-ROM drive
- Note that BitLocker Drive Encryption also requires a TPM 1.2 chip or a USB 2.0 flash drive
The requirements above are a little low to actually get the most out of a Vista operating system, we think Vista users should have a computer system with the following minimum specifications:
- A processor with a minimum speed of 2.0GHz (dual-core recommended)
- 2GB of RAM for x86 (32-bit) systems, 4GB for x64 (64-bit) rigs
- A GPU that supports DirectX 9 and the following:
- WDDM (Windows Vista Display Driver Model) Driver
- 256MB of video RAM
- Hardware support for Pixel Shader 2.0
- 32 bits per pixel
- 100GB SATA hard drive with 50GB free
- CD/DVD burner
This means users upgrading to Windows Vista Ultimate, Vista Home Premium, or any of Vista’s versions, may have to upgrade their computer hardware before they can enjoy the benefits of Vista. In addition, new features like Vista’s SideShow, Vista’s technology that lets the user display data your system pushes to secondary screens, requires beefed up hardware.
Powerful Vista Ultimate computer systems being sold today use Intel Core 2 Quad processors, 8GBs of RAM, and 1500 GBs of memory, probably a little more powerful than most home computers.
