AMD Radeon RX Vega 64
About GPU
The AMD Radeon RX Vega 64 is a powerful GPU that provides impressive performance for gaming and graphic-intensive tasks. With a base clock of 1247MHz and a boost clock of 1546MHz, this GPU is capable of delivering smooth and high-quality visuals. The 8GB of HBM2 memory and a memory clock of 945MHz ensure that there is enough memory bandwidth to handle demanding applications and games.
With 4096 shading units and a 4MB L2 cache, the RX Vega 64 is well-equipped to handle complex rendering and compute tasks. Its TDP of 295W means that it may require a beefy power supply to operate at its full potential, so users should ensure their system can accommodate this power draw.
In terms of performance, the RX Vega 64 offers a theoretical performance of 12.66 TFLOPS, as well as impressive benchmark scores such as 7539 in 3DMark Time Spy. In real-world gaming scenarios, it can achieve high frame rates, with 129 fps in Battlefield 5 at 1080p and 92 fps in Shadow of the Tomb Raider at 1080p.
Overall, the AMD Radeon RX Vega 64 is a solid choice for gamers and content creators looking for a high-performance GPU. Its excellent performance in both synthetic benchmarks and real-world gaming scenarios make it a compelling option for those in need of a powerful graphics card.

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.
98.94 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.

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.
