MIPS competes with ARM in tablets and ultraportables for example. A somewhat popular SoC is the Ingenic JZ4770 which is used in many low-end 7" Android tablets (The first Android 4.0 tablet, the Novo7 Basic, used that SoC).
How the Ingenic MIPS SoC compares to various ARM based ones in benchmarks is easily found with a Google search.
Regarding the openness of the MIPS architecture: The designs are of course copyright protected. The instruction set contains some instructions for unaligned memory access which are patent encumbered. Early Loongsoon CPUs (2E and before) contained workarounds for the patented instructions, but now STMicro has purchased a license from MIPS Technologies so the workarounds could be dropped.

How does MIPS compare against other architectures?
Is MIPS more open than any other architectures?
Why would I want a Loongson CPU instead of any other CPU?
Does it offer anything that others don't? Does it have any advantage?
For performance advantages disadvantages etc more knowledgeable people will answer you.

OpenGL started life as GL, the graphics library used by SGI (Silicon Graphics).
SGI was also the first major user of MIPS processors (starting late 1980s), the first to use MIPS64, and at some point they even bought the company behind the MIPS technology.
So basically, you can say OpenGL was literally designed for MIPS, and most 3D/CGI work for Hollywood during the 1990s was probably done on MIPS-based computer systems (both OpenGL workstations and render servers).

Originally posted by blackiwid View PostI dont think there is a way to buy the longson 3 thing in europe, I did only find a shop that sells the older 2er one for 200 bucks or so... but if it would really cost 1000 bucks and its the normal classic 2,5 year guarantied death by design thing... I would not buy it... btw, I have problem that I like this thinkpoint thing... but who knows... maybe in 2-3 years the next or next-next book is something for me...
but maybe I switch finaly to intel... if they get this gpu-accellerated video shit in low-cost chips then...
Loongson 3A Notebook "can be shipped within 3 days" 840.00 ? "price excl. VAT, excl. delivery"
