RS690MC
Software Compatibility
The graphics driver for the RS690M is fully compatible with all other ATI Radeon class graphics controllers from AMD.
A single driver can support multiple graphics configurations across AMD's product lines, including the ATI Radeon
family and the AMD chipset family. In addition, this driver compatibility allows the RS690M to benefit immediately from
AMD's software optimization and from the advanced Windows
®
XP and Windows Vista support available in the ATI
Radeon family drivers.
1.2
RS690MC
The RS690MC is a special variant of the RS690M that does not support a PCI-E interface for external graphics or a
TMDS interface that enables DVI/HDMI. Beyond the differences, all information in this document that applies to the
RS690M is also applicable to the RS690MC, unless otherwise specified.
1.3
RS690T
The RS690T is a special variant of the RS690M that supports a x8 PCI-E graphics link and has a 16-bit side-port memory
interface for DDR2 memory to be used as a local frame buffer (see
section 1.5.2, “Memory Interface (RS690T Only),”
details). Beyond the differences, all other information in this document is applicable to the RS690T, unless otherwise
specified.
1.4
RS690E
The RS690T and RS690E are the same device with respect to their form, fit, and functionally, except for the differences
described in
All information in this databook that is applicable to the RS690T, unless
superseded by the information given in
is also applicable to the RS690E.

RS690M Features
1.5.1 CPU HyperTransport
™
Interface
•
Supports the mobile and desktop Athlon 64/Athlon 64 FX/Athlon X2/AMD Sempron/AMD Turion 64 processors,
including both AM2 and S1 socket CPUs.
•
Supports 200, 400, 600, 800, and 1000MHz HyperTransport (HT) interface speeds.
•
Supports LDTSTP interface, CPU throttling, and stutter mode.
1.5.2 Memory Interface (RS690T Only)
•
Supports an optional dedicated local frame buffer (side-port) of up to 128MB through a 16-bit interface.
•
New highly flexible memory architecture allows asymmetric side-port and shared system memory frame buffer sizes.
•
New dynamic memory allocation scheme improves performance and reduces power simultaneously.
•
Support for DDR2 system memories up to DDR2-800, with a maximum memory clock speed of 400MHz. Memory
clock is independent of any other clock source and can therefore be set to any frequency equal to or less than
400MHz (DDR2-800), allowing the use of lower speed side-port memories.
•
Support for 16Mx16, 32Mx8, 32Mx16, 64Mx8, and 64Mx16 memory devices.
•
Asynchronous HyperTransport and memory controller interface speeds.
•
Supports DDR SDRAM self refresh mechanism.
•
Supports dynamic CKE and ODT for power conservation.
1.5.3 ATI HyperMemory™ Technology
•
Supports ATI HyperMemory™* technology.
