AMD vừa tiết lộ các thông số kỹ thuật của GPU Radeon Pro 5000M được sử dụng bên trong MacBook Pro 16 inch mới ra mắt, bao gồm Radeon Pro 5300M và 5500M, mang đến hiệu năng tốt hơn với tối đa 8GB GDDR6 VRAM.
Hôm qua [13/11], Apple đã chính thức ra mắt MacBook Pro 16 inch mới với các mẫu GPU thuộc dòng Radeon Pro 5000M của AMD, mang đến hiệu suất đồ họa được cải thiện đáng kể so với các tùy chọn trước đây dành cho MacBook Pro 15 inch từng được giới thiệu vào giữa năm nay.
Bên cạnh card đồ họa Intel được tích hợp sẵn, MacBook Pro mới cũng được trang bị GPU Radeon Pro 5300M với 4GB VRAM GDDR6 trong model tiêu chuẩn. Trong khi đó, model còn lại sử dụng card đồ họa Radeon Pro 5500M và có hai tùy chọn bộ nhớ là 4GB VRAM GDDR6 và 8GB VRAM GDDR6.
Series Radeon Pro 5000M được xây dựng trên kiến trúc RDNA mới của AMD, đồng thời là GPU di động riêng biệt đầu tiên được sản xuất trên quy trình 7nm. Nhờ sử dụng GDDR6, GPU sẽ có băng thông bộ nhớ lên tới 192GB/s, gấp đôi so với GDDR5 mặc dù chỉ Radeon Pro 5500M mới có bộ nhớ VRAM 8GB RAM, trong khi 5300M bị giới hạn ở 4GB RAM.
GPU Radeon Pro 5500M được trang bị 24 đơn vị tính toán, bộ xử lý 1,536 luồng, xung nhịp lên đến 1300 MHz và có thể cung cấp tới 4 teraflop hiệu suất điểm nổi đơn. GPU Radeon Pro 5300M có 20 đơn vị tính toán và 1,280 bộ xử lý luồng, cùng với tốc độ xung nhịp tối đa 1250 MHz, mang lại hiệu năng lên tới 3.2 teraflop.
Ngay cả với phiên bản tiêu chuẩn của MacBook Pro 16 inch, Apple tự tin rằng người dùng hoàn toàn có thể nhận được hiệu năng đồ họa nhanh hơn 2.1 lần so với các GPU trên model trên trước đó. Nếu như bạn chưa biết, MacBook Pro 15 inch được trang bị GPU Radeon Pro 555X và 560X, cả hai đều đi kèm với 4GB VRAM.
When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
The number of pixels that can be rendered to the screen every second.
Floating-point performance is a measurement of the raw processing power of the GPU.
The number of textured pixels that can be rendered to the screen every second.
The memory clock speed is one aspect that determines the memory bandwidth.
Shading units [or stream processors] are small processors within the graphics card that are responsible for processing different aspects of the image.
TMUs take textures and map them to the geometry of a 3D scene. More TMUs will typically mean that texture information is processed faster.
The ROPs are responsible for some of the final steps of the rendering process, writing the final pixel data to memory and carrying out other tasks such as anti-aliasing to improve the look of graphics.
Memory
The effective memory clock speed is calculated from the size and data rate of the memory. Higher clock speeds can give increased performance in games and other apps.
This is the maximum rate that data can be read from or stored into memory.
VRAM [video RAM] is the dedicated memory of a graphics card. More VRAM generally allows you to run games at higher settings, especially for things like texture resolution.
Newer versions of GDDR memory offer improvements such as higher transfer rates that give increased performance.
A wider bus width means that it can carry more data per cycle. It is an important factor of memory performance, and therefore the general performance of the graphics card.
Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.
Features
DirectX is used in video games, with newer versions supporting better graphics and features. The latest version is DirectX 12 Ultimate, which includes support for ray tracing, mesh shaders, and variable rate shading [VRS].
OpenGL is used in games, with newer versions supporting better graphics.
Some apps use OpenCL to apply the power of the graphics processing unit [GPU] for non-graphical computing. Newer versions introduce more functionality and better performance.
The graphics card supports multi-display technology. This allows you to configure multiple monitors in order to create a more immersive gaming experience, such as having a wider field of view.
load GPU temperature

A lower load temperature means that the card produces less heat and its cooling system performs better.
Ray tracing is an advanced light rendering technique that provides more realistic lighting, shadows, and reflections in games.
Allows you to view in 3D [if you have a 3D display and glasses].
DLSS [Deep Learning Super Sampling] is an upscaling technology powered by AI. It allows the graphics card to render games at a lower resolution and upscale them to a higher resolution with near-native visual quality and increased performance. DLSS is only available on select games.
AMD SAM / Intel Resizable BAR

General info
The thermal design power [TDP] is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.
A higher transistor count generally indicates a newer, more powerful processor.
Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.
Peripheral Component Interconnect Express [PCIe] is a high-speed interface standard for connecting components, such as graphics cards and SSDs, to a motherboard. Newer versions can support more bandwidth and deliver better performance.

When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction. Note: This may vary by region.
The graphics card uses a combination of water and air to reduce the temperature of the card. This allows it to be overclocked more, increasing performance.
