The RSX 'Reality Synthesizer' is a proprietary graphics processing unit (GPU) codeveloped by Nvidia and Sony for the PlayStation 3 game console. It is a GPU based on the Nvidia 7800GTX graphics processor and, according to Nvidia, is a G70/G71 (previously known as NV47) hybrid architecture with some modifications. The RSX has separate vertex and pixel shader pipelines. The GPU makes use of 256 MB GDDR3 RAM clocked at 650<!--// NOT 700!!!//--> MHz with an effective transmission rate of 1.4 GHz and up to 224 MB of the 3.2 GHz XDR main memory via the CPU (480 MB max).

A sample flow of data inside the RSX would see them first processed by 8 vertex shaders. The output are then sent to the 24 active pixel shaders, which can involve the 24 active texture units. Finally, the data is passed to the 8 Raster Operation Pipeline units (ROPs), and on out to the GDDR3. Note that the pixel shaders are grouped into groups of four (called Quads). There are 7 Quads, with 1 redundant, leaving 6 Quads active, which provides us with the 24 active pixel shaders listed above (6 times 4 equals 24). Since each Quad has 96kB of L1 and L2 cache, the total RSX texture cache is 576kB. General RSX features include 2x and 4x hardware anti-aliasing, and support for Shader Model 3.0.

Although the RSX has 256MB of GDDR3 RAM, not all of it is useable. The last 4MB is reserved for keeping track of the RSX internal state and issued commands. The 4MB of GPU Data contains RAMIN, RAMHT, RAMFC, DMA Objects, Graphic Objects, and the Graphic Context. The following is a breakdown of the address within 256MB of the RSX.

== Local GDDR3 Memory Physical Structure==
== Chipnumers @ SKU's ==
* Total Memory 256MB
The following is a small sample of serial numbers of the RSX by model number.
* 2 Partitions (128MB)
* 64bit bus per partition
* 8 Banks per partition (16MB)
* 4096 Pages per bank (4KB) -> 12bit Row Address
* Memory block in a page -> 9bit Column Address
* Minimum access granularity = 8 bytes -> same as buswidth between RSX <> GDDR

== RSX Memorymap ==
 
Although the RSX has 256MB of GDDR3 RAM, not all of it is useable. The last 4MB is reserved for keeping track of the RSX internal state and issued commands. The 4MB of GPU Data contains RAMIN, RAMHT, RAMFC, DMA Objects, Graphic Objects, and the Graphic Context. The following is a breakdown of the address within 256MB of the RSX.

Besides local GDDR3 memory, main XDR memory can be accessed by RSX too, which is limited to either:
* 0MB - 256MB (0x00000000 - 0x0FFFFFFF)
::-or-
* 0MB - 512MB (0x00000000 - 0x1FFFFFFF)


==Speed, Bandwidth, and Latency==
==Speed, Bandwidth, and Latency==
System bandwith (theoretical maximum):
*Cell to/from 256MB XDR : 25.6 GB/s
*Cell to RSX (IOIFO): 20GB/s (practical : 15.8GB/s @ packetsize 128B)
*Cell from RSX (IOIFI) : 15GB/s (practical : 11.9GB/s @ packetsize 128B)
*RSX to/from 256MB GDDR3 : 20.8GB/s (@ 650MHz)
Because of the aforementioned layout of the communication path between the different chips, and the latency and bandwidth differences between the various components, there are different access speeds depending on the direction of the access in relation to the source and destination. The following is a chart showing the speed of reads and writes to the GDDR3 and XDR memory from the viewpoint of the Cell and RSX. Note that these are measured speeds (rather than calculated speeds) and they should be worse if RSX and GDDR3 access are involved because these figures were measured when the RSX was clocked at 550Mhz and the GDDR3 memory was clocked at 700Mhz. The shipped PS3 has the RSX clocked in at 500Mhz (front and back end, although the pixel shaders run separately inside at 550Mhz). In addition, the GDDR3 memory was also clocked lower at 650Mhz.

Because of the VERY slow Cell Read speed from the 256MB GDDR3 memory, it is more efficient for the Cell to work in XDR and then have the RSX pull data from XDR and write to GDDR3 for output to the HDMI display. This is why extra texture lookup instructions were included in the RSX to allow loading data from XDR memory (as opposed to the local GDDR3 memory).

The RSX is dedicated to 3D graphics, and developers are able to use different API libraries to access its features. The easiest way is to use high level PSGL, which is basicially OpenGL|ES with programmable pipeline added in. At a lower level developers can use LibGCM, which is an API that talks to the RSX at a lower level. PSGL is actually implemented on top of LibGCM. For the advanced programmer, you can program the RSX by sending commands to it directly using C or assembly. This can be done by setting up commands (via FIFO Context) and DMA Objects and issuing them to the RSX via DMA calls.

Speculatively it is likely that the very first numbers are the actual rom version (a01, b01, b03, b07, b08...) despite Sony's documentation claiming otherwise, DECR-1000 units with rom version b07 and above (and perhaps some others that have not yet been encountered) are not capable of running any firmware lower than 1.60 (from sdk 160.008) this is because the rom version is unknown/unsupported in older lv1 which will fail to initialize the RSX hardware and will cause lv1 to output a "rsx rom abort!" message, this will in turn create an exception early in lv2 boot process as it tries to use the RSX and creates a hard brick several RSX related errors such as "lv2(2): # __rsxaudio_intr_create_thread 983 ffffffff" or "graphics error 512 : 00012625 c221bbb0" ; "lv2(2): page fault handler (DSI): invalid access address 0x795d00e8!".
 
There is nothing in the documentation warning you about this and there is nothing preventing you (or a legitimate developer) to install an unsupported firmware as the vsh allows updating/downgrading to 1.00 or higher and the min praxis for those units is actually lower than 1.00. (0.08 to be exact)
Should this issue occur to you, other than sending the unit back to Sony for servicing, the only way to fix this is to flash an ebootrom (as lv0 still runs fine and is in charge of handling flashing the system memory through lcnslsrv) the problem with that is that sony never released/issued an ebootrom for a firmware higher than 1.00.002 , so officially one would have no choice but to return the unit, that said, considering the ebootrom format is not rocket science and is actually documented (it's a very slight variation of the coreos package format, there are no specific checks whatsoever preventing you from crafting your own, it is not hashed, nor encrypted), you could (as we did) convert the PUP file of a higher firmware and flash it onto the unit to get a full recovery.
