Launch of Radeon HD 6670/6570/6450

After the Radeon HD 6800/6900/6700 series, the AMD Radeon HD 6000 graphics card family has quietly added a number of new members today, and all use the second generation of new DX11 cores, but only for the OEM field, not for the retail market .

AMD Radeon HD 6670: core code "Turks" (Tex Island), 480 stream processors (80 more than Redwood Radeon HD 5670), 24 texture units, 32 Z/Stencil ROP units, 8 Color ROP unit, core frequency 800MHz, single-precision floating-point performance 768GFlops; memory configuration bit width 128-bit, particle GDDR5, capacity 512MB-1GB, equivalent frequency 4GHz, bandwidth 64GB/s; system bus interface PCI-E 2.1 x16.

The card supports AMD Eye-Definition, AMD Eyefinity, AMD EyeSpeed, AMD HD3D, AMD CrossFireX and a series of technologies, including DirectX 11, OpenGL 4.1, OpenCL 1.1, DirectCompute 11, APP, UVD3, DisplayPort 1.2, HDMI 1.4a, 24x MSAA/SSAA, MLAA, up to four screen outputs (up to six screens with DP 1.2 MST), audio source output, and more.

AMD Radeon HD 6570: The core code is also "Turks" (Tex Island), the number of operating units is unchanged, but the core frequency is reduced to 650MHz, single-precision floating-point performance 624GFlops; memory bit width is still 128-bit, but Two types of particles are selected: GDDR5 is the same as above, DDR3 capacity is 512MB-2GB, equivalent frequency is 1800MHz, and bandwidth is 28.8GB/s.

The support technology is basically the same as the above, except that Eyefinity is slightly streamlined. A single card supports up to three screens of output, and a DP 1.2 MST can also achieve six screens.

AMD Radeon HD 6450: core code "Caicos" (Caycos Island), 160 stream processors (double Cedar Radeon HD 5450), 8 texture units, 16 Z/Stencil ROP units, 4 Color ROP units, Core frequency 625-750MHz, single-precision floating-point performance 200-240GFlops; memory configuration is also very flexible, bit width 64-bit, optional GDDR5, DDR3 two kinds of particles, capacity is 512MB-1GB, the former frequency 3200-3600MHz, The bandwidth is 25.6-28.8GB/s. The latter frequency is 1066-1600MHz and the bandwidth is 8.5-12.8GB/s.

The support technology is still quite comprehensive, and only CrossFireX dual card crossfire is eliminated. Eyefinity itself supports three-screen output, and the DP 1.2 MST can only reach four screens.

By convention, this card will inevitably appear in large numbers in low-end desktops, all-in-ones and other branded products.

In addition, AMD released the new Radeon HD 6000A series for the first time on the All-in-One integrated desktop (all-in-one/all-in-one computers), and the models are even richer, including:

Radeon HD 6670A
Radeon HD 6650A
Radeon HD 6550A
Radeon HD 6450A
Radeon HD 6350A

AMD did not announce the specific specifications of these special graphics cards, but it must also be Turks, Caicos cores, specifications and OEM versions should also be similar.
