They are both based on the RV770 GPU, packing 956 million transistors and being produced on a 55 nm process. The Radeon HD 4850 was announced on Jwhile the Radeon HD 4870 was announced on June 25, 2008. Open CL 1.0 to 1.1 are supported for all Chips with RV7xx.

OpenCL accelerates many scientific Software Packages against CPU up to factor 10 or 100 and more. These two features increase total bandwidth for dual-GPU designs to 21.8 GB/s. Subsequent generations of dual-GPU design also feature an interconnect for inter-GPU communications through the implementation of a CrossFire X SidePort on each GPU, giving extra 5 GB/s full-duplex inter-GPU bandwidth. This generation of dual-GPU design retains the use of a PCI Express bridge, PLX PEX 8647 with a power dissipation of 3.8 watts inclusive of PCI Express 2.0 support, allowing two GPUs on the same PCI Express slot with doubled bandwidth over the past generation of product (Radeon HD 3870 X2).

The RV770 GPU also supports an Accelerated Video Transcoding (AVT) feature, which has video transcoding functions being assisted by the GPU, through stream processing.

The RV770 series GPU also supports xvYCC color space output and 7.1 surround sound output (LPCM, AC3, DTS) over HDMI.

The free and open-source driver requires Linux kernel 3.10 in combination with Mesa 9.1 (exposed via the widely adopted VDPAU) ), offering full hardware MPEG-2, H.264/MPEG-4 AVC and VC-1 decoding and the support for dual video streams, the Advanced Video Processor (AVP) also saw an upgrade with DVD upscaling capability and dynamic contrast feature.

Support is available for Microsoft Windows at release, for Linux with Catalyst 8.10. The SIP block UVD 2.0-2.2 implemented on the dies of all Radeon HD 4000 Series Desktop gpus, 48xx series is using uvd 2.0, 47xx-46xx-45xx-43xx series is using uvd 2.2. The internal ring bus from the R520 and R600 has been replaced by the combination of a crossbar and an internal hub.

RV770 features a 256-bit memory controller and is the first GPU to support GDDR5 memory, which runs at 900 MHz giving an effective transfer rate of 3.6 GHz and memory bandwidth of up to 115 GB/s. The RV770 also has 10 texture units, each of which can handle 4 addresses, 16 FP32 samples, and 4 FP32 filtering functions per clock cycle. The RV770 retains the R600's 4 Quad ROP cluster count, however, they are faster and now have dedicated hardware-based AA resolve in addition to the shader-based resolve of the R600 architecture. The RV770 extends the R600's unified shader architecture by increasing the stream processing unit count to 800 units (up from 320 units in the R600), which are grouped into 10 SIMD cores composed of 16 shader cores containing 4 FP MADD/DP ALUs and 1 MADD/transcendental ALU. All products implement TeraScale 1 microarchitecture.
