In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 8970M are marginally better than the AMD Radeon HD 7970M.

The Radeon HD 8970M and the Radeon HD 7970M have both the same core clock speed and the same Texture Fill Rate. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The Radeon HD 8970M and the Radeon HD 7970M have both the same core clock speed and the same Pixel Fill Rate. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The Radeon HD 8970M was released over a year more recently than the Radeon HD 7970M, and so the Radeon HD 8970M is likely to have better driver support, meaning it will be more optimized for running the latest games.

The Radeon HD 8970M and the Radeon HD 7970M have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The memory bandwidth of the Radeon HD 8970M and the Radeon HD 7970M are the same, which means the Radeon HD 8970M and the Radeon HD 7970M have equal limitations when it comes to graphical data transfer.

Both the Radeon HD 8970M and the Radeon HD 7970M have 1280 Shader Processing Units. While the two GPUs have the same number of SPUs, the actual performance delivered by the . Knowing that the shader performance of the Radeon HD 8970M is superior, it is not necessary to examine the GPUs' respective Texture and Pixel Fill Rates.

The Radeon HD 8970M requires 100 Watts to run and the Radeon HD 7970M requires 100 Watts. The two GPUs require the same amount of wattage to run. As such, there is no need to worry about which will more significantly affect your yearly electricity bills.

GPU Mini Review

Mini ReviewOverview
Radeon HD 8970M is a High-End Mobile Graphics Card based on the Second Revision of the GCN Architecture.

Architecture
The GCN 1.1 Release adds support for AMD's TrueAudio Technology which does calculations of audio effects "better" than the CPU and further improves the Powertune Technology.

GPU
It equips a GPU codenamed Neptune XT which has 20 Compute Units activated and thus offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs. The Central Unit Initially Operates at 850MHz and goes up to 900MHz, in Turbo Mode.

Memory
The GPU accesses a 2GB frame buffer of fast GDDR5, through a 256-bit memory interface. The size of the frame buffer is adequate. The memory clock operates at 1200MHz.

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.

Power Consumption
With a rated board TDP of 100W, it is suited for very large laptops.

Performance
Radeon HD 8970M is essentially a fast Radeon HD 7970M.
Gaming benchmarks put its performance slightly above NVIDIA's GeForce GTX 680M.

System Suggestions
We recommend a Powerful Processor (Intel Core i7 Mobile) and 8GB of RAM for a system with Radeon HD 8970M.
Overview
Radeon HD 7970M is a High-End Mobile Graphics Card based on the First revision of the GCN Architecture.

Architecture
The GCN Architecture succeeds the 40nm Terascale Architecture. In addition to being produced with a 28nm Technology, the GCN Architecture adds other Technologies that allow for energy efficiency. For example, ZeroCore Power, a long idle power saving technology, allows the Graphics Cards to shut down by itself when the Monitor is turned off.
GCN also adds Improved Anisotropic Filtering, DirectX 11 Tessellation and the Partially Resident Textures (PRT) Technology, which enables future games to utilize ultra-high resolution textures with the same performance as today's small and often repetitive textures.

GPU
It equips a GPU codenamed Wimbledon XT which has 20 Compute Units activated and thus offers 1280 Shader Processing Units, 80 TMUs and 32 ROPs. The Central Unit Operates at 850MHz.

Memory

Features
DirectX 11.0 Support (11.0 Hardware Default) and support for Crossfire, PowerTune Technology, Eyefinity, App Acceleration, HD3D, ZeroCore Power and other technologies.

Power Consumption
With a rated board TDP of 100W, it is suited for very large laptops only.

Performance
Gaming benchmarks put its on average with NVIDIA's GeForce GTX 680M.
