The HD 6900 series also features AMD's PowerTune technology, which automatically adjusts GPU power draw by dynamically controlling clock speeds, allowing gamers advanced performance inside of the power envelope they specify. The 6900 series also comes with an HDMI 1.4a output. This means that it's now possible to drive multiple monitors off of a single root DisplayPort. It also features a refined texture filtering engine and supports the DisplayPort 1.2 standard, which doubles DisplayPort's bandwidth to 21.6Gbps, giving DisplayPort a significant bandwidth lead over dual-link DVI. The dual 8th generation tessellation units deliver up to 2.9x tessellation performance compared to ATI Radeon HD 5870 graphics. The Cayman GPU also implements AMD's 8th generation tessellator, which implies is the 7th generation tessellator with even further enhancements. With AMD Radeon HD 6900 series graphics, AMD has further enhanced its GPU design efficiency, realizing a 10 percent improvement in performance/mm2. In the biggest change to AMD's core GPU architecture, AMD is moving to the VLIW4 architecture, which allows better utilization than the pervious VLIW5 design, according to AMD. So the HD 6950 features the same amount of transistors with the HD 6970 but also less stream processors, texture units and memory:

TDP is 200W, while idle power is the same as with the 6970 at 20W.Īs you see in the table below, the HD 6950 featuring a stripped down version of the Cayman's PRO GPU, which also powers the HD 6970 card. The core clock is set to 800MHz, while the memory clock is 1250MHz. The Radeon HD 69 stream processors, 88 texture units, and still all 32 ROPs attached to the same 2GB of GDDR5.

The card is utilizing AMD's Cayman PRO GPU chipset, which has a redesigned microarchitecture aimed against Nvidia's Fermi-based solutions.

AMD released its Radeon HD 6950 earlier this year, strategically positioned perform faster than the company's HD 6800 series as well as Nvidia's GTX 460 GPUs and the recently released GeForce GTX 560 Ti.
