DirectX® 11 Multi-Threading

Application, DirectX runtime, and DirectX driver can each run in separate threads

Tasks like loading a texture or compiling a shader can execute in parallel with main rendering thread

Order Independent Transparency (OIT)

Efficient rendering of many overlapping transparent objects

Smoke, fire, hair, foliage, fences, water, glass

Rendering transparent objects correctly requires sorting

Blending is an order dependent operation

DirectCompute 11 simplifies OIT by sorting transparent pixels in one shader pass

Uses atomic operations and append buffers

Render Post-Processing

Apply filter kernel to every pixel in rendered image Depth of field, motion blur, tone mapping, edge detection, smoothing, sharpening

Requires data from neighbouring pixels

Example: constant time filter spreading Accurately simulates certain lens

effects such as depth of field

Novel processing techniquedeveloped at AMD in conjunctionwith UC Berkeley

DirectCompute greatly simplifiesimplementation while increasingperformance and visual fidelity

– Alpha buffer tricks no longer needed –fewer artifacts

– Shared memory optimizations –better performance

Shadow Rendering

HDAO (High Definition Ambient Occlusion)

Detects “valleys” in scene geometry and darkens them according to depth

Contact hardened shadows

Sharpens shadow edges where they contact casting object, make edges increasingly blurry as they get farther away

Anti-Aliasing

Smoothes jagged edges around objects

More obvious in moving images and at lower resolutions

Takes multiple samples of image

More samples = higher quality, but also much more work

Radeon products support 2x, 4x, and 6x sample modes

Tessellating the Right Way

Can add significant detail to a scene while effectively compressing geometry

But excessive use of tessellation can be inefficient for today’s GPUs Poor utilization of rasterizers Overshading Too many polygon edges for MSAA

Brute force approach is wasteful

Morphological Anti-Aliasing

Post-process filtering technique accelerated with DirectCompute

Delivers full-scene anti-aliasing

Not limited to polygon edges, alpha-tested surfaces, etc.

Faster than super-sampling

Performance similar to edge-detect CFAA, but applies to all edges

Compatible with any DirectX® 9/10/11 application

Including games with no AA support

Enabled via AMD Catalyst Control Center™

POWER MANAGEMENT

Performance por watt

• US datacenters consume more power than five 1000 megawatt nuclear power plants – at a cost of almost $3 billion

• This is 150% more than the consumption in 2001

Power savings improvment

AMD PowerTune Technology

Clamps GPU TDP to a pre-determined level

Integrated control processor monitors GPU activity real time

GPU includes counters across all blocks which are monitored and applied to an algorithm to infer power draw

Dynamically adjusts clock to enforce TDP

Provides direct control over GPU power draw (as opposed to indirect via clock/voltage tweaks)

Algorithmic approach guarantees consistent performance across each product variant

No longer need to constrain default clock speeds to allow for outlier applications

User controllable via AMD OverDrive Utility

PowerTune – Game Power Draw

Games consistently operate at lower power than peak apps

With PowerTune, each product variant is tuned to maximize game performance

Outlier applications are still handled gracefully

Accommodates future application power draw
