Complete AMD Radeon HD 8000 Graphics Cards Specs




It's one thing to know that a company is preparing a new range of graphics cards, and another to know what those cards will be and what specifications they bear. That is why we didn't skim over this Chiphell forum post.

AMD's Radeon HD 8000 series of desktop graphics cards will be powered by the GCN 2.0 architecture which, in turn, comes in multiple versions. One of them is called GCN 2.0 Curacao architecture and has 55 million transistors, all inside a die of 420 mm2. The GPU boasts 2,304 stream processors, 144 TMUs, 36 CUs and 48 ROPs, while the clock speed is of 1,100 MHz. Meanwhile, the 6 GB of GDDR5 VRAM operate at 7 GHz over an interface of 384 bits. For something priced at $599 / €599, the parameters aren't that bad (floating point performance of 5.07 TFLOPS). The TDP is 250W and the advantage over the HD 7970GHz is of 35%.

The second video card, Radeon HD 8950, has the XT 28nm process GCN2.0 Hainan architecture, with 35 million transistors and 270 mm2 die size. There are 28 CUs, 1,792 stream processors, 112 TMUs, 32 ROPs and a memory interface of 256 bits. The GPU operates at 1,200 MHz, while the 4 GB of GDDR5 VRAM function at 7 GHz. Everything demands 190W of energy. The price of the Radeon HD 8950 video board will be of $399 / €309 – 399. The performance is 10% superior to HD 7970GHz.

The third card, HD 8870, is 40% better than the HD 7870 and has a price of $299 / €231 – 299. It has a GCN 2.0 GPU with 32 ROPs, 24 CUs, 1,536 SP, 256-bit interface and 1,100 GHz speed. As for the 2 GB VRAM, they work at 6 GHz. The adapter has a TDP of 160W. Finally, the HD 8850, powered by the Hainan LE 28nm GCN 2.0 GPU, has 20 CUs, 1,280 SPs, 80 TMUs, 32 ROPs and 256-bit memory interface. The GPU and memory run at 1 GHz and 6 GHz, respectively, and the TDP is of 130W. Sales will start sooner or later for $229 / €177 – 229. The board will be 15% faster than HD 7870. The information is more or less the same as what was rumored last year.
