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 FirePro V8700.

The HD 7870 was released over three years more recently than the FirePro V8700, and so the HD 7870 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the FirePro V8700 when running the latest games.

The HD 7870 has 1024 MB more video memory than the FirePro V8700, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the HD 7870 also has superior memory performance overall.

The HD 7870 has 51.2 GB/sec greater memory bandwidth than the FirePro V8700, which means that the memory performance of the HD 7870 is much better than the FirePro V8700.

The Radeon HD 7870 PCS+ Vortex II Edition has 1280 Shader Processing Units and the FirePro V8700 has 800. However, the actual shader performance of the HD 7870 is 1251 and the actual shader performance of the FirePro V8700 is 390. The HD 7870 having 861 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 FirePro V8700.

The FirePro V8700 requires 151 Watts to run but there is no entry for the HD 7870. We would recommend a PSU with at least 500 Watts for the HD 7870 and a PSU with at least 450 Watts for the FirePro V8700. The HD 7870 has been recommended a PSU with 50 Watts more than the FirePro V8700. The difference is significant enough that the HD 7870 may have a slight adverse affect on your yearly electricity bills in comparison to the FirePro V8700.

GPU Mini Review

Mini ReviewRadeon 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.
The FireGL line is designed for multimedia content creation programs, such as 3DS Max, mechanical engineering design software such as Solidworks, and civil engineering architectural software such as Chief Architect, whereas Radeon counterparts are suited towards video games. FireGL drivers were built with maximum image quality and pixel precision, with CAD specific functionalities such as the recently introduced AutoDetection Technology to tune the parameters inside the driver to achieve maximum performance for predefined list of software. However, because the drivers are also based on the Catalyst drivers made for the Radeon line, it makes them suitable for gaming, at the expense of probable compatibility issues with the very latest games due to the age of the drivers, with FireGL cards in theory pushing more data than their Radeon gaming counterparts
The ATI FireGL range of video cards, renamed to FirePro 3D in late 2008, is the series specifically for CAD (Computer Aided Design) and DCC (Digital Content Creation) software, usually found in workstations.
