4 What additional processing is performed before/during/after capture (CD focus, face detection, lens distortion correction, noise reduction, image manipulation, etc.), and how that processing is performed;
5 Whether any of the chip interfaces are multiplexed to serve multiple purposes;
6 How well optimized the interface between the sensor chip and the processor is;
7Whether the processor or any other chip is underclocked to reduce power consumption.
Those are just off the top of my head.
I really don't agree that the K30 offers 20% of what the Milbeaut 6 does -- to me, they look pretty well matched.
1, un likely, the SDRAM are super fast probably around 6400 MB/s transfer rate.
The bus and interface are part of the image processor, so that what futsji stated is the whole chip.
2. well that's 6fps, not the limit for the image processing. the buffer simply gets fully and so the camera slows down because it needs room before the next photo can be taken.
3. could be but they must really screwed it up for RAW then...
4. not with RAW. And that's the strange thing, jpeg preformance is fine but raw... it looks like an addition to the processor. An after thought.
5. chip is made up of 5 different sectors with each his own tasks, so it can multi task very well. The milbeaut that is.
6. that's firmware, already named.
7. maybe but seriously doubt that.
well match?
the 6th gen milbeaut can calculate 112 MP per second, the K-30 can mechanically take 96 MP per second so the buffer shouldn't get full.
At the moment at 6fps the camera buffer is full after 8 photos and with 3fps the buffer is full after 10 photos so we can roughly calculate the amount of photos he can process.
If i'm right it can do 1.2 photo each second so that means it does 19,2 MP per second... that's nowhere near the 122 MP the 6th gen milbeaut should be able to do, it's 17% to be precise. Good if the processor did half of the claimed speed then okay but 1/6th is quite ridiculous.
Beside that, it has buffer for 8 photos for RAW and with 30 photos for JPEG so the processor that is used is highly optimized for JPEG preformance, leading me to believe it's a processor meant for those markets JPEG is the main file type. The K3 will be aimed at RAW shooters so they hopefully wont use this processor.
