A Ryzen 4800u actually uses up to 25W TDP, depending upon implementation. And it’s 45% slower in single core. Most importantly, the M1 is estimated to cost Apple $65, the 4800u is a $300+ part.
That price is a meaningless comparison, you can't buy the Apple processor in retail. What's the cost to procedure the AMD part? Something similar I'd guess.
AMD on it’s current hot steak has gotten its gross profit margins to 43%, which would make the cost to manufacture a $300 part around $171.
Two and a half times higher cost to build a slower, more power hungry CPU is not actually very similar.

5950X is 105W desktop CPU. Apple M1 is for laptops and Mac Mini.
You can buy it in a Mac Mini, and an iMac eventually no doubt. The "laptop"/"desktop"-grade chip distinction is pretty arbitrary here.
> The "laptop"/"desktop"-grade chip distinction is pretty arbitrary here.
This is the first of their CPUs. The iMac will almost certainly be running a higher end CPU which at the very least supports more RAM. It's likely the 16" MacBook Pro and the higher end 13" MacBook Pro will share a CPU with the iMac the same way the Mac mini and the MacBook Air share a CPU.

#424This really flips the argument that Mac hardware is overpriced and underpowered on its head. Now Apple computers are a premium product from a performance perspective, as well.
Not quite. You can't synthetically compare one chip to another and draw organic conclusions. Apple computers with M1 don't support the software that I use. That's why I bought a fully spec'd Intel MBP13 today. All this talk about battery life and benchmarks gets flipped on its head when I can't use the product in the real world.

#425Can somebody explain how is M1 going to work on larger GPU tasks (rendering, encoding etc) with it's memory bandwidth M1 total memory bandwidth is 68.2 GB/s (128 bit LPDDR4x-4267) AMD Radeon Pro 5600m memory bandwidth is 394.2 GB/s (2048 bit HBM2) https://www.techpowerup.com/gpu-specs/radeon-pro-5600m.c3612
68.2GB/s is a ton of bandwidth. Actually, very, very few tasks on a desktop can stress a CPU enough to saturate the bandwidth on a single task. Proper HPC programs written to have absolutely zero cache misses can. A javascript eating 1GB of RAM to show some text, and pictures, cannot.

- Mac has ~10% of the global market for end user machines. It doesn't now, never has, and never will own the market nor does it desire to sell cheap enough machines to do so. - Given that you can't add ram after the fact and 256GB is anemic the cheapest laptop that is a reasonable choice is $1400. - The cheapest desktop option is $6000 with an 8 core cpu or 8000 with a 16 core. - The average end user spends $700 on a…
The average user was spending peanuts on phone before iPhone. They also had 0% market for phones.

The iPhone was mid-range at launch, $499 versus $730 for a contemporary smartphone like the N95

> What in the world is an actual professional? I would say that generally , a "professional" user of pretty much any tool, is someone for whom the tool's quality is a constraint on their professional productivity. A professional paint user is an artist. A professional telescope user is an astronomer—or a sniper. A professional typewriter user is a stenographer. A professional shoe user is an athlete. In all these cas…
I'm a professional programmer... hardware constraints aren't exactly the limiting factor when i use vim all day.
You don't compile your code?
Obviously it depends greatly on what kind of software you are writing, but at all my dev jobs, I eventually end up waiting for some amount of time while the CPU heats the room up.
Notably, VIM is inevitably more gentle on my CPU than VSCode and similar.

#428AMD's Zen 3 (Ryzen 5xxx series) are beating the Apple M1 in single core score: https://browser.geekbench.com/v5/cpu/singlecore As another datapoint Ian (of Anandtech) estimated that the M1 would need to be clocked at 3.25Ghz to match Zen 3, and these systems are showing a 3.2Ghz clock: https://twitter.com/IanCutress/status/1326516048309460992
Zen 3 is sold out it seems for now

We don’t know yet, there could be some binning involved.
They could be identical, and the choice is just different thermal envelopes. Active vs passive cooling can make a huge difference for some work loads.

No, they aren't. All of the top results have crazy overclocking and liquid cooling. You need to look the numbers here: https://browser.geekbench.com/processor-benchmarks . Top end Zen 3 is slightly lower than M1.
Not exactly. You can check the clock speeds: https://browser.geekbench.com/v5/cpu/4620493.gb5 Up to 5050MHz is stock behavior for the 5950X and it's using standard DDR4 3200 memory.
Yet it still makes it very clear: a properly implemented ARM core can easily bury an X86 of equivalent size because of inherent advantage of not having to pay interest on 40 years of technical debt in the ISA.
