The Evolution of Intel Graphics Processing Units (GPUs)
A Brief History of Intel’s GPU Journey
The journey of Intel’s Graphics Processing Units (GPUs) began in the early 1990s, with the company’s first attempt at creating a dedicated graphics processing unit (GPU). In this article, we will explore the key milestones in Intel’s GPU development, from its inception to the present day.
The Early Days: Intel’s First GPU Attempt
In 1991, Intel’s first GPU attempt was the Intel 81046. This chip was designed to be a low-power, low-cost solution for embedded systems, such as set-top boxes and digital video players. The Intel 81046 was a 32-bit GPU that used a 16-bit bus and had a clock speed of 10 MHz.
| Feature | Description |
|---|---|
| Architecture | 16-bit bus |
| Clock Speed | 10 MHz |
| Memory | 16 KB |
| Bus Width | 16 bits |
| Number of Cores | 1 |
The Rise of Direct3D and DirectX
In the mid-1990s, Intel’s GPU development shifted towards Direct3D, a graphics API developed by Microsoft. Direct3D was designed to be a low-level API that allowed developers to create high-performance graphics applications. Intel’s Intel 81046 was one of the first GPUs to support Direct3D, and it played a key role in the development of the DirectX API.
| Feature | Description |
|---|---|
| Direct3D | Low-level API for graphics applications |
| DirectX | API for high-performance graphics applications |
| Intel 81046 | First GPU to support Direct3D |
| DirectX 6.0 | Released in 1998, DirectX 6.0 was a major update to the DirectX API |
The Advent of DirectX 7 and 8
In 1999, Intel released DirectX 7, which introduced several significant improvements to the DirectX API. DirectX 7 included support for Direct3D 7.0, which was a major update to the Direct3D API. Intel’s Intel 81046 was still used in DirectX 7, but it was eventually phased out in favor of newer GPUs.

In 2002, Intel released DirectX 9, which introduced several significant improvements to the DirectX API. DirectX 9 included support for Direct3D 9.0, which was a major update to the Direct3D API. Intel’s Intel 81046 was still used in DirectX 9, but it was eventually phased out in favor of newer GPUs.
| Feature | Description |
|---|---|
| DirectX 9 | Released in 2002, DirectX 9 was a major update to the DirectX API |
| DirectX 9.0 | Released in 2003, DirectX 9.0 was a major update to the DirectX API |
| Intel 81046 | Still used in DirectX 9 |
The Advent of DirectX 11 and 12
In 2006, Intel released DirectX 11, which introduced several significant improvements to the DirectX API. DirectX 11 included support for Direct3D 11.0, which was a major update to the Direct3D API. Intel’s Intel 81046 was still used in DirectX 11, but it was eventually phased out in favor of newer GPUs.
| Feature | Description |
|---|---|
| DirectX 11 | Released in 2006, DirectX 11 was a major update to the DirectX API |
| DirectX 11.0 | Released in 2007, DirectX 11.0 was a major update to the DirectX API |
| Intel 81046 | Still used in DirectX 11 |
The Advent of DirectX 12 and 13
In 2013, Intel released DirectX 12, which introduced several significant improvements to the DirectX API. DirectX 12 included support for Direct3D 12.0, which was a major update to the Direct3D API. Intel’s Intel 81046 was still used in DirectX 12, but it was eventually phased out in favor of newer GPUs.
| Feature | Description |
|---|---|
| DirectX 12 | Released in 2013, DirectX 12 was a major update to the DirectX API |
| DirectX 12.0 | Released in 2014, DirectX 12.0 was a major update to the DirectX API |
| Intel 81046 | Still used in DirectX 12 |
The Advent of Vulkan and OpenCL
In 2015, Intel released Vulkan, an open-source graphics API that was designed to be more efficient and flexible than DirectX. Vulkan was initially developed by AMD, but Intel acquired the technology and released it as part of its Intel Graphics Technology (IGT) suite.
| Feature | Description |
|---|---|
| Vulkan | Open-source graphics API |
| Vulkan 1.0 | Released in 2015, Vulkan 1.0 was a major update to the Vulkan API |
| Intel IGT | Released in 2015, Intel IGT was a suite of graphics technologies developed by Intel |
The Advent of AMD Radeon and NVIDIA GeForce
In 2016, AMD released Radeon and GeForce, which were designed to compete with Intel’s Intel Graphics Technology (IGT) suite. Radeon was based on Vulkan, while GeForce was based on DirectX.
| Feature | Description |
|---|---|
| Radeon | Based on Vulkan |
| Radeon 4.0 | Released in 2016, Radeon 4.0 was a major update to the Radeon API |
| GeForce | Based on DirectX |
| GeForce 10.1 | Released in 2016, GeForce 10.1 was a major update to the GeForce API |
