Does Macbook pro 2020 intel uses ECC?

No.

Again: Mac Pro, and Xserve, have ECC. The former is still available, the latter is long retired.

While there are a scattering of Intel Core and Intel Celeron processors with ECC featurs available, none are used (or are used with ECC) in the Apple product line.

In the Apple product line, the Mac models with ECC are all based on Xeon processors.

Presently, no Apple silicon Mac models offer ECC.

No Apple laptops offer ECC, Intel or Apple silicon.

What any future Mac might offer, we do not know.

Various Mac Pro and Xserve models are Intel Xeon and have used ECC.

MacBook Pro 2020 Intel models use Intel Core processors and not Intel Xeon, and lack ECC.

MacBook Pro 2020 was a transitional year, with two Intel models and one Apple silicon model.

I suspect you’re encountering some naming confusion between MacBook Pro, and Mac Pro, which are quite different models.

Actually i dont got naming confusion, I just wonder if macbook pro 2020 have ecc, cause i am a mobile developer and i got anxoius with simple system performance issues

No. No ECC. Apple doesn’t offer ECC on laptops, or ECC on anything with an Intel processor that’s not Xeon.

Intel support for ECC is targeted on servers and workstations, and is rather thin on desktops, and is ~nonexistent on mobile.

Apple have not announced any Apple silicon processor Macs with support for ECC.

ECC and redundant memory and other “reliability, availability, and scalability” features tend to be found on higher-end, and more expensive, configurations. In Intel, that’s a target market (mostly) shared with Xeon, though there are some non-Xeon Intel x86-64 processors with ECC given the right hubs and the right parts. But not Apple laptops.

No, the mini does not use Xeon processors.

In addition to wider memories to hold additional check bits for each word, there is substantial additional very fast Hardware that has to work at memory-cycle speeds to implement Error Detection and Correction. In the Intel line, that extra hardware has only been made available in the Xeon processors. Mac Pro and iMac Pro use those Xeon processors and have that feature.

as MrHoffman has stated, Apple has not made any announcement about when, and whether they will include ECC on their yet-to-be-abnnounced high-end Macs. At this writing, ECC it is not offered on any Apple Silicon Macs.

And to be absolutely clear, ECC is considered a reliability, availability, and scaling (RAS) feature, and not a performance feature.

While ECC is becoming more prevalent, its added costs and performance effects have traditionally kept it and other so-called RAS features reserved to multi-user configurations, timesharing (ask the older IT folks 😉), servers, and high-end and high-capacity configurations. This is where RAS sells.

Outside of high-end workstations, ECC has been comparatively rarely made available on single-user configurations.

As memory capacities increase on even the lower-end computers, and as ECC-capable processors become more power-efficient, that’ll shift; ECC and other RAS features will become more widely available.

But for now, ECC remains fairly rare below the more expensive and higher-end workstation and server configurations.
