AMD Radeon HD 6770
About GPU
The AMD Radeon HD 6770 GPU is a solid mid-range graphics card that offers good performance for its price point. With a memory size of 1024MB and memory type of GDDR5, it provides decent memory bandwidth and speed, making it capable of handling most modern PC games and applications.
The 800 shading units and 1.36 TFLOPS theoretical performance allow for smooth and efficient rendering of graphics, even in more demanding games. The GPU's memory clock of 1200MHz also contributes to its overall performance, ensuring snappy and responsive gameplay.
The 256KB L2 cache helps to reduce memory latency and increase overall efficiency, while the 108W TDP is relatively low for a GPU of this caliber, making it a fairly energy-efficient option for desktop systems.
One potential drawback of the Radeon HD 6770 is that it may struggle with some of the latest AAA games at higher settings, particularly at higher resolutions. Additionally, the card lacks modern features such as support for ray tracing and DLSS, which may be important for some users.
Overall, the AMD Radeon HD 6770 is a solid choice for budget-conscious gamers or content creators looking for a mid-range GPU. It offers good performance for its price, making it a worthwhile option for anyone in need of a reliable graphics card for their desktop PC.

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.
13.60 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.

FP32 (float)
?
An important metric for measuring GPU performance is floating-point computing capability. Single-precision floating-point numbers (32-bit) are used for common multimedia and graphics processing tasks, while double-precision floating-point numbers (64-bit) are required for scientific computing that demands a wide numeric range and high accuracy. 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.
