Thread: XFX Radeon HD 5770 graphic license

The ASUS ARES or the Sapphire Radeon HD 5970 TOXIC revised not only the ATI Radeon HD 5970, but sat the bar in performance upwards. Looking on the other hand on the middle class falls, especially Power Color in the eye, so many of the 3D-accelerator with Killer NIC, or even equipping Hydra chip. But XFX could now move into the spotlight and presented with his XFX Radeon HD 5770 single-slot another special form of the popular video card. Rather than rely on the usual dual-slot cooler, built-to a much smaller single-slot version, which strongly recalls the layout of a reference ATI Radeon HD 4850th Then the little 3D accelerator otherwise suffered no cuts and is still equipped with standard frequencies of 850 respectively 2400 MHz, a 1024-MB GDDR5 video memory and a total of 800 stream processors,

Freeing the XFX Radeon HD 5770 from its single-slot cooler shall submit to AMD's RV840 free. This is already running in TSMC 40 nm off the line and can come up with particularly frugal power consumption and a respectable performance. But compared to the RV870 big-brother, Instead of the full 20 SIMD units of the Cypress core is only ten SIMD available. This brings the number of Shader units reduced to 160 in 5 D configurations, as each thread of 16 SIMD processors, which are divided further into five stream processors, is available. At each SIMD unit TMU is also a quad-coupled, with what it brings to a total of 40 of the RV840 texture mapping units. Since the memory interface compared to the top models to just two 64-bit controllers was circumcised,
