CPU benchmark

Our processor / CPU comparison helps you to compare two CPUs. We use benchmark results from Cinebench R20, Cinebench R23 and Geekbench 5 as well as the FP32 raw performance (GFLOPS) of the iGPU.

This might be our first look at Apple’s blazing-fast next-gen M1X chip

The M-series chip that might power some of Apple’s 2021 MacBook Pro and iMac versions has apparently just leaked. The M1X could be the successor of the M1, powering devices like the unannounced 14-inch MacBook Pro, 16-inch MacBook Pro, and 27-inch iMac. A leaked M1X benchmark indicates the chip...

Maybe I am out of the loop, but what is the difference between "h264" and "AVC"? I thought they were just names for basically the same thing (like HEVC and h265).

The website _claims_ (it is pretty obviously not that trustworthy) that the M1X would have Enc/Dec capabilities for h264, but only decoding for AVC...

Apple is following a unified memory architecture for their mobile Apple Silicon SoCs. If the next Apple Silicon SoC (called here the M1X) can support 32 GB of RAM then to keep it consistent with that architecture the GPU would need to address 32 GB. And if Apple plans on using this SoC for a 16" MacBook Pro replacement, 32 GB is not enough to match what is currently available. Ask yourself, would Apple really replace the Intel 16" MacBook Pro with an Apple Silicon notebook that couldn't address as much RAM as Intel? It doesn't seem likely. That means this SoC needs to be able to address 64 GB for both the CPUs and GPUs. The specs listed don't make much sense in that regard.

What do you want to debunk here? They just took M1 specs and scores and multiplied it by two. CPU-monkey is a trash website that tries to generate as much incoming traffic as possible. And of course everyone else follows suite because writing about M1X will make people click.

Frankly, for all we know CPU-monkey might have copied verbatim one of my posts from a year ago where I was speculating about possible AS configurations. It does t take much skill of knowledge.

CPU Monkey got the M1 key-specs correctly listed right after the M1 launch keynote. Thus I wouldn't call their M1X information ******** but I wouldn't put too much trust in them either. That being said, I think the specs they list are very likely for a M1X. Benchmarks of course are ********.

Common sense. If you read the article you know that its not legit but more like estimate based on M1. Just look at the numbers. Its super clear.
This should not fool the community here at all.

An M1X powered iMac could be an amazing machine, particularly with more GPU power on offer.

The GPU performance on the M1’s is my only real “meh” area with them.

The current M1's sport 7 and 8GB on board GPU, and 16GB RAM total. I think I get what you're saying, but I don't believe it's a linear path like that. Is there a technical reason you believe that a 16GB GPU would limit the RAM to 32GB?

It would do you good to check what the numbers 7 and 8 mean in relation to the M1 and its GPU.

Absolutely. When the CPU will be scoring over 14k, people will quickly decide 32 GB is enough.

No, the GPU's in M1 have 7 or 8 cores. Not related to memory. The GPU has access to all unified memory.

Would Apple replace an existing laptop line with one that couldn't address as much RAM as Intel? Yes; They just did this with M1 MacBook Pro 13.

The MBP16 *may* have a 64GB limit...if it uses an "M2", which I expect to arrive later than an M1X, which I estimate will support up to 8p+4e CPU cores, 16 GPU cores and 32GB RAM. If the MBP16 is available mid-2021 I would expect a 32GB maximum.

Time will tell!

Ouch! Thanks for reminding me, I forgot about that in the specs. I’m just curious about what everyone is doing that’s using more than 32GB unified memory on a laptop? I do music mostly and even with big sample libraries I’ve only maxed out the 24GB in my Mac Pro a few times. Don’t get me wrong I’m getting the 32GB model when it comes but only as insurance, and right now we’re still talking about conjecture here. I seriously doubt the AS iMac Pro and Mac Pro will have issues with RAM.

No they didn't. The 2 port 13" MacBook Pro could only be bought with 16 GB of RAM (and 2 TB of SSD). Apple is very unlikely to produce a lesser Mac with an M1 to replace an existing Intel version. Bad optics. They are already getting killed for only having 1 external display on the MacBooks.

They didn’t... the two-port Intel 13” never supported over 16GB...
