ZiiLABS ZMS-08 ARM Cortex A8 Media Processor

1Ghz ARM Cortex HD Media Rich Applications Processor

The 3rd generation ZMS-08 media-rich applications processor brings 1080p Blu-ray quality H.264 decode to low-power devices. Delivering more than four times the performance of previous generation devices, the ZMS-08 combines the flexible multi-format media processing capabilities of the Stemcell Computing array with an 1GHz ARM Cortex processor and rich peripheral integration to deliver the low-power, high performance media-rich processing required of next-generation devices.

Blu-ray Quality 1080p H.264 Video Decode
1080p H.264 Video Encode
720p H.264 Video Conferencing
Accelerated OpenGL ES 1.1/2.0
Xtreme Fidelity X-Fi Audio Technology
Multi Format Media CODECs
ARM Cortex-A8 at 1GHz
Accelerated Graphics and Compositing
Advanced Image Signal Processing
Rich Peripheral Integration & Connectivity

I think the ZMS-08 is based on ARM Cortex A8 processer (ARM licensed their processor design to OEM companies who then manufacture the processors with their own custom specs).

ARM Cortex-A8 at 1 GHz
256K L2 Cache
NEON
TrustZone Security Technology
1 GByte Addressable RAM
32K I/D Caches

You can find out the specs for the ARM cortex A8 processor from ARM website:
Cortex-A8 Processor - ARM


So ZiiLabs couples the ARM Cortes A8 processor with Ziilabs' own "Flexible Stemcell Computing Array"

The Stemcell computing array features 64 fully programmable floating point processing elements that off-load the intensive media processing tasks from the ARM CPU to deliver superior media capabilities coupled with improved application performance. This flexibility enables users to experience the widest range of existing and emerging media standards.

Multi-format Video, Image and Audio CODECs
2D/3D Graphics and Compositing
Image Processing
Integer and Floating Point
Audio Processing
Offloads the ARM Core
Low-power, High Compute Density


So after reading what is on ARM website and Creative's website, I think that there are very little variations in the different versions of ARM cortex A8 processors in the market. Ziilabs seemingly only added 64 Floating Point Processing Elements to the ARM cortex Processor... and they spent a fortune to do so...

wonders if there are any benchmarks on the different customised versions of ARM cortex processors in the market.

and also different combined performance in using different 2D/3D graphics processing chips like the the GPU in Tegra2 or PowerVR-based graphics processing core.


--------------------------------------
Tegra 2 features a bunch of individual processing cores on a single chip, each of which can be turned off or scaled back to carefully manage power consumption. There's an audio processing core, a 2D/3D graphics processor, an HD video decoding processor (capable of smooth 1080p playback), an HD video encoding block, an audio processor, and a still image processor.

Tegra 2 upgrades the ARM11 CPUs in the original chip to the ARM Cortex A9. The Cortex A9 is avilable with up to 4 cores, but Tegra 2 ships with a dual-core version. This is a substantial improvement - the Cortex A9 is an out-of-order speculative superscalar processor that offers 2.5 Dhrystone MIPS per core at speeds up to 1GHz. It's safe to say it's several times faster than the ARM11 cores in the original Tegra, and a significant step up from even the Cortex A8 found in products like the iPhone 3GS.

Well the tools we have are Linpack, GLBenchmark, and a whole lot more... I don't really know off the top of my head...

Basically you have have the base applications processor, but what surrounds it can differ, also manufacturing processes... They will do some tweaks as well...
