So sánh amd radeon vega 8 graphics năm 2024

The AMD Radeon RX Vega 8 is an integrated GPU for notebooks. It is used for the Ryzen 7 APUs of the Renoir generation (Ryzen 4000 Mobile) and Cezanne (Ryzen 5000 Mobile). The GPU is based on the Vega architecture (5th generation GCN) and has 8 CUs (= 512 of the 704 shaders) clocked at up to 1,750 MHz (Ryzen 7 4800U) or 2,100 MHz (Ryzen 9 5980HX). The performance depends on the configured TDP (12-25 W at launch), the clocks, the cooling, and the memory configuration). The GPU should benefit from fast dual-channel DDR4-3200 RAM (contrary to DDR4-2133 single-channel, which is also possible). Compared to the similar Radeon RX Vega 8 in the Raven Ridge generation (Ryzen 2000 Mobile), the GPU is clocked significantly higher (1.750 versus 1.100 MHz Boost, +59%).

The Vega architecture offers some improvements over the Polaris generation and now supports DirectX 12 Feature Level 12_1. More information is available in our dedicated article about the Raven Ridge architecture.

The performance is clearly faster than the old RX Vega 8 thanks to the higher clock speed and faster main memory (if used). Still it is positioned in the entry level (compared to dedicated graphics cards) and only suited for low demanding games.

Thanks to the modern 7nm process and clever power-saving features, the power consumption is comparatively low (according to AMD), so the graphics card can also be used for slim and light notebooks.

The following benchmarks stem from our benchmarks of review laptops. The performance depends on the used graphics memory, clock rate, processor, system settings, drivers, and operating systems. So the results don't have to be representative for all laptops with this GPU. For detailed information on the benchmark results, click on the fps number.

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

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.

GDDR version

Unknown. Help us by suggesting a value. (AMD Radeon Vega 8)

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.

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.
