Have you looked at the processor differences? Pre-fetch, caching, instruction cycles, etc.?
|
|
|
|
|
Some of them.

Clock speed is only part of the equation. For instance, if this processor can do an operation in half the number of clock cycles then it will show a 50% improvement even at the same clock speed (at least for that instruction).

I'm well aware of that.
Now name a processor architecture that one 32-bit processor will have that another will not, that - clock speeds considered equal, runs over 3 times faster than the next one.
Especially given both processors are superscalar.
There's a profound difference here, and it can't be readily explained by clock speed or CPU architecture.

What is the memory bus width on both systems?
Back in the old days, some of the chip families had similar CPU, but 8, 16, or 32 bit memory bus. 2 fetches to grab a 16bit instruction on an 8 bit bus.
With the newer CPUs, maybe your floating point library is 100% cached on the 600MHz

I think part of the reasoning for the 8 bit bus, less pins means cheaper, easier boards

On this issue part of me wants to take a page from Mostly Harmless wherein Arthur Dent is talking about Perfectly Normal Beasts. Nobody has any idea where they come from. Some fear if they search for the answer, the question might be taken away, so to speak. This kind of feels like that to me.

I wanna say since they're probably using similar SRAM chips it would be similar, but I can't be sure how any of it is configured to that detail without poring over datasheets.

I've been wanting to switch over to ARM Cortex processors for awhile - I figure coding against them opens a lot more doors for me than just using boutique Tensilica CPUs for example.
The Teensy is Arduino compatible, and the most capable (by far) of the Arduino compatible MCUs on the market. The ARM it uses is a superscalar 32-bit 600mhz processor, with branch prediction, and 64-bit floating point coprocessing. It also has two programmable USB ports, SPDIF, I2S, I2C, SPI, a zillion PWM channels, SDMMC and stuff I don't even remember right now.
So for those of you that have been dabbling in IoT, or want to, I can recommend the Teensy, particularly version 4.1
They are costlier than most other kits, but well worth it. You'll understand where the money went.
I'll probably still use ESP32s sometimes, but the Teensy blows them away.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

I hate it when you hit 3 letters directly, the possibilities seem endless then.
