You really don't have any clue on what you're posting do you?. Copying definitions from google isn't gonna help you this time.
You are doing nothing but making a fool out of yourself by comparing a CISC x86 processor with a vector processor.
Btw, a RISC cpu is incapable of complex or macro operations. It takes simple or micro-operations and has extremely low instruction set support compared to what x86 offers.
Your comparison between jaguar and cell really showed your degree of intelligence.
Cell is an HSA unit. It incorporates simd units ( vector processors) in form of SPE's. They work on a huge array of data for a single instruction but incapable of handling complex instructions, ( game console hardly needs these).
Consider the following example:
You have an instruction:
Now this is a single operation. Vector processors has the ability to work on a huge data set which x86 cpu's are incapable of.
Lets say, you have 100 data items that works on the above operation.
PHP:
for ( i = 0 ; i<=99 ; i++){
a[i] *= 2b[i];
}
So you see, 100 values of 'a' is operated with 100 values of 'b' and assigned to 'a' again .All have different results. This is parallel processing that a vector processor is capable of .
It can work on 100 sets of data in a single cycle whereas a cpu takes multiple cycles as it isn't as parallel as a vector processor.
But cpu can perform complex operations on single data sets efficiently. You don't have to break it down that often.
For example - SQRT (x) is a complex operation and an x86 cpu doesn't have to break it down. They have a massive amount of instruction set support that does the job.
Read up to know how.
Do you know now how foolish it was to compare jaguar and cell in IPC context? Cell's PPE is based on ibm's power pc architecture. But in cell, it just used for scheduling and feeding instructions to the spe's. More like a branch predictor in a conventional cpu front-end. Spe's are vector processor and works in the way i explained before. They are chained, have a common repository with a ring bus like structure so that data can be shared. They are capable of handling gpu functionalities too except rendering as they don't have ROP'S.
Spe's can do vertex shading like a gpu and thus offloads a lot of task from RSX. It can also be used in GPGPU computing like ray tracing which ps3 exclusives bring.
So cell is an HSA architecture just like AMD JAGUAR + AMD GCN in the ps4. The compute engines in a GCN are vector processors like SPE's but have far better IPC and throughput than cell. The peak compute performance is 1.84 teraflops and that's a lot. PS3's CELL doesn't even come close.
Now you realize how flawed you points were? And hey, don't make a laughing stock of yourself by comparing a multi chip module with an APU.
Do you even know what a heterogeneous architecture is ?
This!!!!
No wonder Nintendo is losing developer support and are destined to be doomed.
