Model ATI Radeon HD 4870 X2 positioned its creators as the fastest graphics adapter in the world. The decision is based on two produced by 55 - nm technology chips RV770 XT, each with 800 streaming processors. Between chip is an updated hardware switch tires PCI Express, endowed with the support of PCI Express 2. 0. Total GDDR5 memory from 256 - bit interface is equal to 1 GB (2 x 512 MB) or 2 GB (2 x 1 GB), with the memory bandwidth reaches 230 Gb/s, while its effectiveness is equal to 3600 MHz frequency. As for the working frequency of graphic cores, it is 750 MHz. In turn, ATI Radeon HD 4850 X2, on applications developers, demonstrates a new level of productivity at a very affordable price. The product is built on the base created by the pair 55 - nm chip technology RV770 PRO, has a 1600 streaming processors (2 x 800), characterized the working frequency of 625 MHz graphics cores and is staffed by 2 GB (2 x 1 GB) GDDR3 memory with a 256 - bit interface and maximum bandwidth 128 Gb/s. Each of the new products formed on printed circuit boards in black, uses the PCI Express bus 2. 0 x16, equipped dvuhslotovoy active air cooling system and fitted with a llife on the back cover of the two ports of Dual-Link DVI and one HDTV-output. In addition, both the accelerator compatible with DirectX 10. 1 Shader Model 4. 1, supports HDMI, HDCP and 7. 1-channel audio, equipped with one CrossFire-connector, as well as"friends"with such advanced technology brand, as ATI CrossFireX Multi-GPU Technology, ATI PowerPlay and second-generation ATI Avivo HD Technology with an enhanced integrated video Unified Video Decoder 2.
If you talk about the same level of productivity products under consideration, then the plan they are ahead NVIDIA GeForce GTX 280, with ATI Radeon HD 4870 X2 does with great gap, demonstrating in some gaming applications impressive superiority, to 80%.
