Manufacturers of the Radeon cards include ASRock, Asus, Biostar, Club 3D, Diamond, Force3D, Gainward, Gigabyte, HIS, MSI, PowerColor, Sapphire, VisionTek, and XFX. The brand was launched in 2000 by ATI Technologies, which was acquired by AMD in 2006 for US$5. 4billion.
About Radeon in brief
Radeon is a brand of computer products, including graphics processing units, random-access memory, RAM disk software, and solid-state drives. The brand was launched in 2000 by ATI Technologies, which was acquired by AMD in 2006 for US$5. 4 billion. Three different families of microarchitectures can be roughly distinguished, the fixed-pipeline family, the unified shader model-families of TeraScale and Graphics Core Next. Manufacturers of the Radeon cards include ASRock, Asus, Biostar, Club 3D, Diamond, Force3D, Gainward, Gigabyte, HIS, MSI, PowerColor, Sapphire, VisionTek, and XFX. On 11 September 2015, AMD’s GPU business was split into a separate unit known as Radeon Technologies Group, with Raja Koduri as Senior Vice President and chief architect. AMD does not distribute Radeon cards directly to consumers. Instead, it sells Radeon GPUs to third-party manufacturers, who build and sell the Radeon-based video cards to the OEM and retail channels. Products up to and including the HD 5000 series are branded as ATI Radeon, while the HD 6000 series and beyond use the new AMD Radeon branding. The first derivative architecture, RV200, did not follow the scheme used by later parts. Early generations were identified with a number and majorminor alphabetic prefix. Later generations were assigned code names. New or heavily redesigned architectures have a prefix of R while slight modifications are indicated by the RV prefix. The only release in this generation was the Radeon 7500, which introduced little in the way of new features but offered substantial performance improvements over its predecessors.
The 4870 and 4870 have the same amount of stream processors yet higher clock rates due to refinements to the video bus. It was a refresh of the 4870 with the 512-bit Gbits memory on an effective bus with 230bits Gbits. It arrived in late June 2008 and has been a success on many computers with many more stream processors, including the latest generation of Intel’s Kaby Lake processors. The HD 4870 has a 512-bits Gbit memory on a 230-bit bus with 4GB of memory. It has a 4870x 1600 stream processor and 512- bit Gbit Memory on aneffective bus with 256GB of RAM. It is a refresh with the same number of stream processor yet higher clocks speeds due to improvements to power consumption and power efficiency. The R300 was the first GPU to fully support Microsoft’s DirectX 9. 0 technology upon its release in 2001. The RV200 was a die-shrink of the former R100 with some core logic tweaks for clockspeed, introduced in 2002. It incorporated fully programmable pixel and vertex shaders. The second generation Radeon included a sophisticated pixel shader architecture. This chipset implemented Microsoft’s pixel shaders 1. 4 specification for the first time. While heavily based upon the previous generation, this line included extensions to the Shader Model 2 feature-set.
