Intel Arc A770
About GPU
The Intel Arc A770 GPU is a powerful and high-performance graphics card designed for desktop platforms. With a base clock speed of 2100MHz and a boost clock speed of 2400MHz, this GPU offers fast and responsive performance for gaming, content creation, and other graphic-intensive tasks.
With a massive 16GB of GDDR6 memory and a memory clock speed of 2000MHz, the A770 GPU offers ample memory bandwidth and capacity for handling large and complex textures, rendering tasks, and high-resolution gaming. The 4096 shading units and 16MB of L2 cache further contribute to the GPU's ability to handle demanding workloads with ease.
The A770 GPU has a TDP of 225W, which means it requires a robust cooling solution to maintain optimal performance and stability under heavy loads. However, the trade-off for this power consumption is the GPU's impressive theoretical performance of 19.66 TFLOPS. This level of performance is further exemplified by the GPU's 3DMark Time Spy score of 13492 and its ability to achieve 105 fps in Shadow of the Tomb Raider at 1080p resolution.
Overall, the Intel Arc A770 GPU is a top-of-the-line graphics card that offers exceptional performance for demanding gaming and professional applications. Its high clock speeds, abundant memory capacity, and efficient shading units make it a great choice for users who require uncompromising performance from their graphics hardware.

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.
307.2 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.

FP16 (half)
?
An important metric for measuring GPU performance is floating-point computing capability. Half-precision floating-point numbers (16-bit) are used for applications like machine learning, where lower precision is acceptable. 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.
