Radeon HD 6000A series attacker can exchange fire with APU

In addition to the new A-series APUs and Athlon II, AMD quietly announced the first Radeon HD 6000A series of discrete graphics cards designed specifically for all-in-one devices. Based on the second-generation DX11 architecture, AMD also supports the acceleration of dual graphics cards with A-series APUs. system.

Radeon HD 6000A series graphics cards include four models: Radeon HD 6670A, Radeon HD 6650A, Radeon HD 6550A, and Radeon HD 6450A. The first three models use Turks core as the Radeon HD 6670/6570 on the desktop, and the last one is Radeon HD. The HD 6450-like Caicos core.

In addition, according to previous news, the series will have a lower-end Radeon HD 6350A, the core or the previous generation Radeon HD 5450, does not support the exchange of APU dual graphics card, but not yet appear in the official product list.

This batch of all-in-one graphics card provides two forms, one is a complete MXM module, the equivalent of a notebook discrete graphics card, can be installed freely, the second is a separate GPU chip plus memory particles, can be directly welded on the motherboard, but the specific product photos also Unpublished, power figures have not been disclosed.

AMD spokesperson Dave Erskine explained: “Depending on the target product form, the graphics card has a different definition, so use the A or M at the end of the model to represent the all-in-one model or the mobile model and distinguish it from the desktop model. OEM Manufacturers can see at a glance that the Radeon HD 6000A series is tailor-made for the unique design of the all-in-one, including heat dissipation, power requirements, feature support, and more."

Radeon HD 6670A development codename "Onega LP", has 480 stream processors, 24 texture units, 8 ROP grating units, the core frequency 800MHz, single-precision floating-point performance 768GFlops, equipped with 218-bit 521MB-1GB GDDR5 memory, etc. Effective frequency 4000MHz, bandwidth 64GB/s, technical support includes DirectX 11, OpenGL 4.1, OpenCL 1.1, PCI-E 2.1, MLAA, Eyefinity (up to four screens per card/up to six screens with MTS), UVD3, HD3D, CrossFireX, etc. And so on, the video output supports VGA, DVI, HDMI 1.4a, DisplayPort 1.2.

The Radeon HD 6650A is exactly the same as the Radeon HD 6670A according to the official specifications, but according to previous news, it should only be replaced with GDDR3.

Radeon HD 6550A development codename "Pinewood", the number of computing units did not decrease, but the frequency and video memory configuration has been reduced. Its core is running at 650MHz with single-precision floating-point performance of 624GFlops. In addition to the 512MB-1GB GDDR5 with 4000MHz frequency, the video memory can use the cheaper 512MB-2GB GDDR3. The equivalent frequency is 1800MHz and the bandwidth is 28.8GB/s. . There is nothing technical to say, but it cannot be extended to six-screen output with DP 1.2 MTS.

The Radeon HD 6450A is codenamed "Casplan", reduced to 160 stream processors, 8 texture units and 8 ROP barrier units, core frequency 625-750MHz, single-precision floating-point performance 200-240GFlops, memory bit width 64-bit, Capacity 512-1GB, on the one hand can choose 3200-3600MHz GDDR5, bandwidth 25.6-28.8GB/s, on the other hand can use 1066-1600MHz GDDR3, bandwidth 8.5-12.8GB/s. The technical support is basically the same as the above, except that the Eyefinity multi-screen outputs a single card with up to three screens, with a DP 1.2 MTS up to four screens.

In addition to being designed for all-in-one applications, the Radeon HD 6000A series graphics cards can also use Dual Graphics dual-graphics technology to hybridize with A-series APUs to further enhance performance and enhance power control flexibility. Specific mix and match, they can all work together with the four-core A8, A6 series, Radeon HD 6550A/6450A can also partner dual-core A4 series.
