Radeon HD 7560D IGP 

Pascal will be more than 2x more performance per watt efficient than Maxwell, even without the three new features listed above.

Most of the detail was around Pascal, due in 2016, that will introduce three new features including mixed compute precision, 3D (stacked) memory, and NVLink.

For most rendering tasks unordered rasterization is fine (deeper elements would be occluded anyhow), but for a certain category of tasks having the ability to efficiently control the access order to a UAV is important to correctly render a scene quickly.

VTRs are primarily meant to be used with volumetric pixels (voxels), with the idea being that with sparse allocation, volume tiles that do not contain any useful information can avoid being allocated, avoiding tying up memory in tiles that will never be used or accessed.

In the meantime, NVIDIA has planned an press event for tomorrow where they will be unveiling some details to the public regarding their upcoming chip however the event will not be live streamed unlike the Game24 event which is scheduled for 18th September and will run live for the entire day.

They have released some very brute and impressive designs over the last couple of years, mainly their iChill series which feature a top of the line air cooler to cool down NVIDIA’s flagship cores.

Finally, in the power efficiency focused fixed frame rate mode, switching between Direct3D 11 and 12 slightly reduces GPU power consumption but dramatically reduces CPU power consumption, all while maintaining the same 19fps frame rate.

With that subject in mind, Intel is doing just that this week at SIGGRAPH 2014, where the company is showcasing both the performance and efficiency gains from Direct3D 12 on their hardware.
