Performance

GPU clock speed

900MHz

1000MHz

The graphics processing unit (GPU) has a higher clock speed.
GPU turbo

1050MHz

947MHz

When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.
pixel rate

28.8 GPixel/s

64 GPixel/s

The number of pixels that can be rendered to the screen every second.
floating-point performance

3.69 TFLOPS

5.12 TFLOPS

Floating-point performance is a measurement of the raw processing power of the GPU.
texture rate

115 GTexels/s

160 GTexels/s

The number of textured pixels that can be rendered to the screen every second.
GPU memory speed

1500MHz

1300MHz

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

3GB

4GB

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.
memory bus width

384bit

512bit

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.
Newer versions of GDDR memory offer improvements such as higher transfer rates that give increased performance.
Supports ECC memory
Sapphire Dual-X R9 280X OC
Sapphire R9 290 Tri-X
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 games, with newer versions supporting better graphics.
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.
Supports multi-display technology
Sapphire Dual-X R9 280X OC
Sapphire R9 290 Tri-X
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.
supports ray tracing
Sapphire Dual-X R9 280X OC
Sapphire R9 290 Tri-X
Ray tracing is an advanced light rendering technique that provides more realistic lighting, shadows, and reflections in games.
Supports 3D
Sapphire Dual-X R9 280X OC
Sapphire R9 290 Tri-X
Allows you to view in 3D (if you have a 3D display and glasses).
supports DLSS
Sapphire Dual-X R9 280X OC
Sapphire R9 290 Tri-X
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.
This benchmark measures the graphics performance of a video card. Source: PassMark.

Newer versions of HDMI support higher bandwidth, which allows for higher resolutions and frame rates.
Allows you to connect to a display using DisplayPort.
Allows you to connect to a display using DVI.
Allows you to connect to a display using mini-DisplayPort.

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.
number of transistors

4313 million

6200 million

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.
Has air-water cooling
Sapphire Dual-X R9 280X OC
Sapphire R9 290 Tri-X
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.
