Compute Performance
The rise of GPU acceleration, GPGPU and various forms of parallel computing mean that the compute performance of GPUs is a noteworthy consideration when choosing which graphics cards to buy. We run three GPU compute benchmarks to give you an idea of how much compute performance each graphics card has.
Basemark (OpenCL)
Basemark CL by Rightware is a comprehensive benchmark tool designed to measure the performance of OpenCL 1.1 implementations on various devices ranging from desktops to embedded systems. Basemark CL uses OpenGL ES 2.0 or OpenGL 2.1 for rendering, depending on the platform. From Rightware.com.
ComputeMark (DX11 Compute)
ComputeMark is first 100% DirectX 11 Compute Shader benchmark and ultimate GPU burner. From ComputeMark.com.
Luxmark (OpenCL)
LuxMark is a OpenCL benchmark tool. The idea for the program was conceived in 2009 by Jean-Francois ‘Jromang’ Romang. The idea was quite simple, wrap SLG inside an easy to use graphical user interface and use it as a benchmark for OpenCL. From LuxRender.net.
What is the performance of this R7 250x in terms of ‘CrossFire”mode. Given the I5 processor is somewhat computationally superior. However one the reasons I would take one of these lower end cards would be to benifit the graphics utility with the AMD Kaveris. I’m fairly certain that the results here,would be at least 20% better with using the AMD platform,and this card. And as with this the question would be which one,and what brand would be the better choice of the user wanting to do so.
I dont know what the equivalent technology is available when running a graphics card on the Intel platform. Although the ‘crossfire’ type scenario might be done. And I realize that ‘crossfire’,is actually a different term when utilized presently with the FM2+/Kaveri platform. Since Crossfire,can be used in dual mode,and it is probably not a default of the platform cpu in that vain. (For example two R7 250xs,or 240s on an ATX using the same processor in your system tests).
The AMD would use the same ideal of a medial system with 1866 memory as well. I know the difference between the two proprieties. I dont know which for the AMD platform would be the best low cost card to do so. And as a kicker the Nvidia vrs Crossfire could be seen as well. And compute would be better too.
Thanks.
