In terms of overall gaming performance, the graphical capabilities of the AMD Radeon HD 7870 PCS+ Vortex II Edition are massively better than the AMD Radeon HD 6750 v2.

The HD 7870 has a 450 MHz higher core clock speed and 44 more Texture Mapping Units than the HD 6750. This results in the HD 7870 providing 66.8 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The HD 7870 has a 450 MHz higher core clock speed and 16 more Render Output Units than the HD 6750. This results in the HD 7870 providing 25.6 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The HD 7870 was released over a year more recently than the HD 6750, and so the HD 7870 is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the HD 6750.

The Radeon HD 6750 v2 and the Radeon HD 7870 PCS+ Vortex II Edition have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The HD 7870 has 134.4 GB/sec greater memory bandwidth than the HD 6750, which means that the memory performance of the HD 7870 is massively better than the HD 6750.

The Radeon HD 6750 v2 has 720 Shader Processing Units and the Radeon HD 7870 PCS+ Vortex II Edition has 1280. However, the actual shader performance of the HD 6750 is 252 and the actual shader performance of the HD 7870 is 1251. The HD 7870 having 999 better shader performance and an altogether better performance when taking into account other relevant data means that the HD 7870 delivers a massively smoother and more efficient experience when processing graphical data than the HD 6750.

The HD 7870 transistor size technology is 12 nm (nanometers) smaller than the HD 6750. This means that the HD 7870 is expected to run slightly cooler and achieve higher clock frequencies than the HD 6750.

The Radeon HD 6750 v2 requires 86 Watts to run but there is no entry for the Radeon HD 7870 PCS+ Vortex II Edition. We would recommend a PSU with at least 450 Watts for the HD 6750 and a PSU with at least 500 Watts for the HD 7870. The HD 7870 has been recommended a PSU with 50 Watts more than the HD 6750. The difference is significant enough that the HD 7870 may have a slight adverse affect on your yearly electricity bills in comparison to the HD 6750.

GPU Mini Review

Mini ReviewOverview
Radeon HD 6750 v2 is a fast-middle-class Graphics Card based on the second revision of the Terascale Architecture.

Architecture
The Second variant of the Terascale 2 Architecture is still manufactured with a 40nm technology and despite allowing more Stream Cores, their design remains more or less the same compared to the first variant.

GPU
It equips a GPU codenamed Juniper PRO which has 9 Compute Units activated and thus offers 720 Shader Processing Units, 36 TMUs and 16 ROPs.

Memory
The GPU accesses a 2GB frame buffer of DDR3, through a 128-bit memory interface. The memory clock operates at 800MHz. The size of the frame buffer is exaggerated and in no way benefits the GPU.

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

Cooling Solution
The Cooling Solution consists of a Single-Fan.

Power Consumption
With a rated board TDP of 86W, it requires at least a 450W PSU with one available 6-pin connectors.

Performance
Gaming benchmarks put its performance on the level of the GDDR5 variant of Radeon HD 6670, meaning GeForce GTX 550 Ti is still much faster.

System Suggestions
We recommend a modest processor (Intel Core i3/AMD Phenom) and 4GB of RAM for a system with Radeon HD 6750.
Radeon HD 7870 PCS+ Vortex II Edition is a special edition of Radeon HD 7870.
This is one of today's most powerful editions of the reference as it features increases in both the core and memory clocks that went from 1000MHz to 1150MHz and from 1200MHz to 1250MHz.
Benchmarks indicate the performance boost is quite extreme and around 8% when compared to the reference Radeon HD 7870.
