The line was partnered with new APIs to provide higher performance than existing OpenGL and Direct3D shader APIs could provide, beginning with Close to Metal, followed by OpenCL and the Stream Computing SDK, and eventually integrated into the APP SDK.įor highly parallel floating point math workloads, the cards can speed up large computations by more than 10 times the earliest and one of the most visible users of the GPGPU, obtained 20-40 times the CPU performance. All support 32-bit single-precision floating point, and all but the first release support 64-bit double-precision. Like the FireGL/FirePro line, they were given more memory and memory bandwidth, but the FireStream cards do not necessarily have video output ports. ![]() The FireStream line is a series of add-on expansion cards released from 2006 to 2010, based on standard Radeon GPUs but designed to serve as a general-purpose co-processor, rather than rendering and outputting 3D graphics. The FireStream line has been discontinued since 2012, when GPGPU workloads were entirely folded into the AMD FirePro line. The AMD FireStream can also be used as a floating-point co-processor for offloading CPU calculations, which is part of the Torrenza initiative. ![]() Originally developed by ATI Technologies around the Radeon X1900 XTX in 2006, the product line was previously branded as both ATI FireSTREAM and AMD Stream Processor. However, Nvidia makes much about the fact that the ATI GPU does not have error correction on its cores and GDDR memory - and AMD acknowledges that's a feature it needs to add.AMD FireStream was AMD's brand name for their Radeon-based product line targeting stream processing and/or GPGPU in supercomputers. And in this case, the ATI Cypress GPU can hold its own against the best Fermi that Nvidia has. While there are some workloads that can use single-precision just fine (some life sciences and oil and gas exploration apps are fine with single precision), most flop heads care about double-precision. With all of its cores working properly, the Cypress GPU can deliver 2.72 teraflops of single-precision and 544 gigaflops of double-precision floating point performance. ![]() The AMD GPU has full support for the DirectCompute 11 and OpenCL 1.0 graphics and number-crunching protocols embedded in its hardware, and also includes 32-bit atomic operations, flexible 32KB local data shares, 64KB global data shares, global synchronization, and append/consume buffers etched onto its silicon. The Cypress chip has 1,600 SIMD engines and a slew of supporting electronics wrapped around them so they can do math with their clothing still intact. With the FireStream GPU co-processors, the units are equipped with a passive heat sink that allows them to slide into rack and tower servers, creating the hybrid 圆4-GPU systems that many think will soon become the norm in the HPC arena. The Cypress GPU gets the normal fan-cooled packaging for the Radeon HD and FirePro discrete graphics cards, with the major difference being that the FirePro cards has more video memory. The Cypress GPU is no slouch, just like Nvidia's Fermi GPUs - and just like Intel and AMD are fierce competitors that get the best of each other every now and again, the competition between AMD and Nvidia drives innovation forward. Today, the Cypress GPUs will be plunked into the third generation of FireStream GPU coprocessors intended for embedded applications where the GPUs do complex math that an 圆4 can't do without both taking its shoes off and pulling its pants down (if it is male) or lifting its shirt up (if it is female). The Cypress GPUs already made their way into the ATI Radeon HD 5870 discrete graphics cards ( last October and the ATI FirePro V8800 graphics cards for high-end workstations ( back in April). Keeping pace with Nvidia in the GPU wars, Advanced Micro Devices has not only launched its "Lisbon" Opteron 4100 processors but also released the embedded versions of its "Cypress" family of GPUs, a counterpunch to Nvidia's "Fermi" chips used in its Tesla embedded GPUs.
