New 4D architecture? First exposure of HD6970 stream processors

The Radeon HD 6800 series has brought a lot of surprises, but the core architecture is still essentially the one from the R600, but don't worry, it doesn't seem necessary to wait until the next generation Radeon HD 7000 series of the South Islands, near the immediate Cayman Radeon. The HD 6900 series is very likely to have a gorgeous turn.

The latest information shows that Radeon HD 6970 will be equipped with 1536 stream processors - very strange numbers, because it is not a multiple of 5, but can be divisible by 4. We know that AMD has been using one or four small 5D stream processor architectures in recent years, so the total amount is a multiple of 5, but if the 1536 figure is true, it directly proves that the Radeon HD 6900 series has been changed to four. The new 4D architecture of the mid-sized unit has also been confirmed. Further calculations, Radeon HD 6970 is likely to be 16 groups of 96 stream processors each. The use of two architectures in different families of the same family is rare.

In addition, Radeon HD 6970 will also have 96 texture units, 32 raster units (ROP), 256-bit 2GB GDDR5 memory, the output interface is the same as Radeon HD 6800 series is two DVI, two mini DisplayPort, one HDMI, hot The design power consumption may be slightly higher than the GeForce GTX 580, but the performance will be stronger.

The Radeon HD 6950 will naturally trim some execution units, but the number of stream processors is not clear. The Radeon HD 6990 is the new dual-core version. The single card integrates two Radeon HD 6970 cores, which is 3072 stream processors.

The user “love296871081” from the ZOL forum also exposed a few spy photos of Radeon HD 6970. The styling and Radeon HD 6800 series are exactly the same, but they are even larger. The tail turbine fan diameter is larger, and the auxiliary power supply interface is six-pin. Plus eight needles, two crossfire goldfinger, said core frequency is 860MHz.
