Characteristics of the 8000 series graphics cards AMD Radeon


It’s one thing to know that the company is preparing a new line of graphics cards, and quite another thing – what these cards are capable of. Thanks to the forum Chiphell we have the opportunity to share with you the characteristics of the new 8000-series graphics cards Radeon off, AMD. But unlike the 770GTX and 780GTX from NVIDIA, this information is, unfortunately, not yet officially confirmed.

Immediately it should be noted that “the eight thousandth” series graphics cards AMD Radeon will be built based on the architecture GCN 2.0, which in turn will be presented in several versions.

One of them, GCN 2.0 Curacao XT, will be built on the 28 nm process technology. Based on it will run the GPU AMD Radeon 8970 with 55 million transistors, located on the movement area of ​​420 mm2. GPU is clocked at 1100 MHz, has 2,304 stream processors, 144 TMU, CU 36 and 48 ROP. Fee get 6 GB of GDDR5 video memory with a frequency of 7 GHz and a 384-bit bus.
The source indicates that the performance floating point operations in the fee is 5,07 TFLOPS. The top model will consume the same 250W power supply, but compared with the model 7970GHz its performance with a 35 percent increase. The cost of AMD Radeon 8970 will be 599 euros dollarov/599.

The second board is indicated Radeon HD 8950, based on the architecture GCN2.0 Hainan (28 nm), with 35 million transistors, covering an area of ​​270 mm2. The processor will have 27 CU, 1792 stream processors, 112 TMU, 32 ROP and 256-bit memory bus.

The GPU frequency will be 1200 MHz. Fee will equip 4 GB of GDDR5 memory with a frequency of 7 GHz. Claimed power consumption is 190 watts. The productivity of new items will be 10 percent higher than the current single-processor flagship HD 7970GHz. Card price will be 399 euros dollarov/309-399.

The third card in the list is the HD 8870, which will be 40 percent faster than the HD 7870 version. At the same time cost fee will be 299 euros dollarov/231-299. It will also use a processor architecture GCN 2.0, 32 ROP, 24 CU, 1536 stream processors, 256-bit memory bus and GPU clock of 1100 MHz. New products will be equipped with 2 GB of memory with a frequency of 6 GHz and 160 W power supply to demand.

The latest model in the list is the HD 8850, based on the processor Hainan LE, with 20 CU, 1280 stream processors, 80 TMU, 32 ROP and 256-bit memory interface. Graphics processor and memory, the novelty will operate at a frequency of 1 GHz and 6 GHz, respectively. Heat dissipation in this case is 130 watts. When the board will be on sale, then it will ask for 229 euros dollarov/117-229.

Performance HD 8850 is 15 percent higher than the HD 7870.
