mounted on the lid
* Other names and brands may be claimed as the property of others.
10-inch screen with 1024x600
resolution
Average 10 hours of battery life
Always connected with Wi-Fi,
Bluetooth*, and WiMAX

Netbooks are bank



~40 million shipped so far

6-month ramp of netbooks was
faster than Apple* iPhone* or
Nintendo* Wii*
~139 million projected by 2013
Approximately 7% of online users
in US report owning a netbook

The Intel® Atom™ Processor
Full x86 IA in size of a grain of rice
• In-order processing
• Supports up to two threads
with Intel® Hyper-Threading
Technology
• Supports SSE3
• Accompanied by Intel® GMA
945, 3150, or 500
• Integrated graphics, I/O,
and memory controller
8
Optimize your game for the
Intel® Atom™ Processor with ICC
 CPU doesn’t re-order instructions…
9
Optimize your game for the
Intel® Atom™ Processor with ICC
 CPU doesn’t re-order instructions…
 Use the Intel® Compiler with the following
flags: /QxL /QxSSE3_ATOM
 Easy 1.2-1.3x speed up
10
Maximize the Intel® Atom™ Processor
with Threading & SSE
 The Intel® Atom™ Processor is an in-order
processor, hyper-threading helps alleviate
bottlenecks that out-of-order processing
would handle
 The Intel® Atom™ Processor has SSE3 support
for faster floating point math (1.1x to 1.3x
speed up)
 Games that already support threading and
SSE will already run with great performance
11
Know Your GFX Chips:
Intel® GMA 945, 3150 & 500
 945 & 3150 are more common
-
DirectX* 9.0c with Pixel Shader 2.0
Vertex processing done on CPU
Texture decompression for DXT1-DXT5 and FXT1
Use strips and indexed vertices over point, line, and triangle
lists
 500 supports hardware vertex processing
 Full screen increases performance (no context
switching with Windows* Vista*/7)
* Other names and brands may be claimed as the property of others.
12
Vertex Processing and Threading
Caveat
 Intel® GMA 945 & 3150 offload vertex
processing to CPU
 The driver will be running along side your app
and utilizing resources
 Threading might incur a performance penalty
13
Overcoming small screen sizes

Position elements on screen
relative to where they belong

Show only options necessary for
game play on screen

Use expressive icons with text on
tooltips for on screen UI
button.x = right + 10
button.y = top + 10
button.x = 100
button.y = 10

Scale art assets based on screen
size/resolution but impose a
minimum size
Back
14
Monitor power events & connectivity
 Use the Intel® Laptop Gaming TDK to track:
- Power source: GetPwrSrc()
- Battery life: GetPercentBatteryLife()
- Network connectivity: Get80211SignalStrength()
 Use Windows* Power Management functions
-
Listen for WM_POWERBROADCAST event
Detect suspend, hibernate, close lid, low battery, and more

15
Add support for ad-hoc gaming
 Intel® Laptop Gaming TDK
-
Create a Personal Area Network for others to join
No Internet infrastructure is required
 Windows* Peer Collaboration API
-
Use People Near Me to find peers
Discover other peers on the same subnet or LAN
* Other names and brands may be claimed as the property of others.

Remote tools are your friend

Visual Studio’s remote
debugger allows you to
develop on a desktop

Tools like GPA support
remote execution

Use VTune‘s Pack and
Go feature

Mapping a network
drive for both machines
makes debugging easier
25
Start with System Analyzer

Examine the CPU and GPU
workload to see the whole
picture

Run System Analyzer from
a remote system
26
If CPU bound,
use Parallel Studio/VTune
Improve performance with:
 Use Intel® Compiler
 Use threading
 Use SSE3
27
If you are GPU bound,
use Frame Analyzer
•
Remember, GMA 945 and
3150 use CPU vertex
processing
•
Minimize multi-pass
rendering and postprocessing
•
Avoid points sprites (use
screen aligned quads)
