The "slave" graphics card needed to be from the same family as the "master".Īn example of a limitation in regard to a Master-card configuration would be the first-generation CrossFire implementation in the Radeon X850 XT Master Card. ATI currently has not created the infrastructure to allow FireGL cards to be set up in a CrossFire configuration. Low-end Radeon x1300 and x1600 cards have no "CrossFire Edition" but are enabled via software, with communication forwarded via the standard PCI Express slots on the motherboard. This dongle serves as the main link between both cards, sending incomplete images between them, and complete images to the monitor. The Master card shipped with a proprietary DVI Y-dongle, which plugged into the primary DVI ports on both cards, and into the monitor cable. One had to buy a Master card, and pair it with a regular card from the same series. "Master" capability is a term used for 5 extra image compositing chips, which combine the output of both cards. Radeon x800s, x850s, x1800s and x1900s came in a regular edition, and a "CrossFire Edition" which has "master" capability built into the hardware. The system required a CrossFire-compliant motherboard with a pair of ATI Radeon PCI Express (PCIe) graphics cards. Configurations First-generation ĬrossFire was first made available to the public on September 27, 2005. For DirectX 12 applications, AMD has the mGPU (also known as multi-GPU) branding, with the difference being that software developers must create mGPU compatible profiles for their applications where before AMD created the profiles for DirectX 11 applications. The CrossFire brand name was retired by AMD in September 2017, however the company continues to develop and support the technology for DirectX 11 applications. Īssociated technology used in mobile computers with external graphics cards, such as in laptops or notebooks, is called AMD Hybrid Graphics. The technology allows up to four GPUs to be used in a single computer to improve graphics performance. AMD Chipset Series ( Hybrid CrossFireX)ĪMD CrossFire (also known as CrossFireX) is a brand name for the multi- GPU technology by Advanced Micro Devices, originally developed by ATI Technologies.As already said about Intel, for the average user a good B550 is enough, while you can bet on an X570 if you require the extra features it offers.ĪM5 only supports DDR5 memory and B650E / X670E chipsets feature PCIe 5.0 support and AMD EXPO technology (Extended Profiles for Overclocking, similar to Intel XMP). Cheaper alternatives are the H670 and B660 (socket LGA 1700, Intel Alder Lake 12th Gen CPUs) – these chipsets are the best choice for the average user.įor AMD, AM4 socket supports A520, B550 and X570 chipsets: the main differences concern the number of SATA and USB 3.2 ports, PCI-e 4.0 lanes, with X570 having the best multi-GPU, overclock and PCI Express 4.0 support. It is worth to choose the top models only if you require the features they offer. Moreover, unlike in the past, you do not need high-end motherboards to have good results in overclocking, so our suggestion remains a midrange Z690 model. It is recommended only to those who overclocks or is interested in having a top tier hardware. The top end Intel chipset is the Z790 (socket LGA 1700, Intel Raptor Lake 13th Gen CPUs) – is the best of the best, but it is relatively expensive as it supports DDR5 memory and PCI-Express 5.0. The second priority is the motherboard chipset. AMD sockets are: AM4 and AM5 (for Ryzen CPUs), TR4 / TRX40 / sWRX8 socket (for Threadripper CPUs). Intel has the LGA1151, LGA1200 and LGA1700 sockets. When picking a motherboard, your first priority is to make sure it has the right socket to match the CPU.
