ATI Radeon HD 4730
About GPU
The ATI Radeon HD 4730 is a mid-range desktop GPU with some impressive specs. The 512MB of GDDR5 memory with a 900MHz memory clock provides solid performance for gaming and multimedia tasks. The 640 shading units and 128KB L2 cache further enhance its graphic capabilities, allowing for smooth and detailed rendering of images and videos.
With a TDP of 110W, the Radeon HD 4730 is relatively power-hungry compared to modern GPUs, but it still delivers a theoretical performance of 0.96 TFLOPS. This means it can handle most modern games and applications with ease, although it may struggle with the most demanding titles at higher settings.
In terms of actual performance, the Radeon HD 4730 is capable of running most games at medium to high settings at 1080p resolution, making it a great choice for casual and mid-level gamers. Its performance is also bolstered by its support for DirectX 10.1 and OpenGL 3.3, ensuring compatibility with a wide range of games and software.
Overall, the ATI Radeon HD 4730 is a reliable and capable GPU for mid-range desktop systems. Its strong memory and shading units, combined with its solid performance metrics, make it a good choice for anyone looking for an affordable and competent graphics card for gaming and multimedia tasks. However, its relatively high power consumption may be a concern for some users.

TMUs
?
Texture Mapping Units (TMUs) serve as components of the GPU, which are capable of rotating, scaling, and distorting binary images, and then placing them as textures onto any plane of a given 3D model. This process is called texture mapping.

Memory Bus
?
The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth
?
Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Pixel Rate
?
Pixel fill rate refers to the number of pixels a graphics processing unit (GPU) can render per second, measured in MPixels/s (million pixels per second) or GPixels/s (billion pixels per second). It is the most commonly used metric to evaluate the pixel processing performance of a graphics card.
6.000 GPixel/s
Texture Rate
?
Texture fill rate refers to the number of texture map elements (texels) that a GPU can map to pixels in a single second.

FP64 (double)
?
An important metric for measuring GPU performance is floating-point computing capability. Double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy, while single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks. Half-precision floating-point numbers (16-bit) are used for applications like machine learning, where lower precision is acceptable.

ROPs
?
The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
