HD7870/7850 official specifications full exposure

The AMD Radeon HD 7800 series will be released next Monday, and the final specifications are also gdm by Japanese media. Or. The jp leaked out, and it was very different from what it was before.

Radeon HD 7800 series development code-named Pitcairn, 28nm process manufacturing, 2.8 billion transistors, with 256-bit 2GB GDDR5 memory, equivalent frequency 4800MHz, bandwidth 153.6GB / s, support ZeroCore technology and thus standby power consumption less than 3W.

The Radeon HD 7870 will have 20 groups of computing units, 1280 stream processors, 80 texture units, 32 ROP units, and 128 Z/Stencil units. Previously, there were 22 computing units, 1408 stream processors, and 88 Texture units, 24 ROP units. Obviously, the card is not as strong as expected, but there are more ROP units.

The core frequency is very high, set at a full 1GHz (previously 950MHz), it is also known as "Radeon HD 7870 GHz Edition", just like the Radeon HD 7770 also broken G.

In addition, its single-precision floating-point performance is 2.56TFlops, texture filling rate is 80GT/s, and pixel filling rate is 32GP/s. The typical power consumption of the entire card is about 175W, requiring double six-pin auxiliary power supply.

Radeon HD 7850 is 16 groups of computing units, 1024 stream processors, 64 texture units, 32 ROP units, 128 Z/Stencil units, the core frequency is reduced to 860MHz, single precision floating point performance 1.76TFlops, texture fill rate At 55 GT/s, the pixel fill rate is 27.52 GP/s and the typical power consumption is about 130 W. A single six-pin auxiliary power supply should be sufficient.

Similar to the previously released Radeon HD 7900/7700 series, the Radeon HD 7800 series will not be immediately available for sale, but will wait until after the 19th, so the price has not been finalized.
