> see my response elsewhere, but these aren't unrelated problems: Apple has higher IPC at a lower power-per-core. You can slide around where on the scale x86 falls - maybe you can match perf/watt but then you're getting wiped by a factor of 3 on performance, and you can match on performance but then you're getting wiped by a factor of 6 on perf-watt. You can't do both at once. I'm not sure how you established that. I…

“Intrinsically linked” doesn’t mean anything, if you want to make an argument then make it. I’ve already made mine - Anandtech shows a factor of 6 difference in perf/watt between a 11980HK and a M1 Max at peak performance, and this likely translates into a ~factor of four-ish difference in perf/watt and IPC at iso-power. That’s a performance gap that is unlikely to be closed by a node shrink - there is a large archit…

> “Intrinsically linked” doesn’t mean anything, if you want to make an argument then make it.

Yes it does, it's refuting your idea that IPC can be considered without looking at cycle time.

And you're trying to make an argument that does not address the question I asked. As I told you in my first reply.

> Ah, so you are conflating “the amount of transistors spent on x86 decoding” with “the architectural impact that x86 has on performance”.

No. Read the conversation from the start, and read the links with comments from people who have actually worked on Apple, AMD, and Intel cores.

Yes, it is the same cpu die with a few enterprise feature flags turned on, it’s no faster, it’s actually slower due to the lower TDP you note. You don’t understand what you’re talking about and you’re openly hostile to the person who tried to explain it to you lol.

You've done much more than banning "the other account." Banning an account does zero - it takes about 5 seconds to get a new one.

Here's what you have done over the last few years: banned the external IPs of a whole bunch of large customer sites, highrise buildings, and huge hotels. Losing many users in the process, and turning the other ones into attackers of your site - for fun. like me. Enjoy your little powertrip, retarded unpaid human who's too dumb to replace himself by a spam filtering script.

When these chips hit the rackmount Mac Pro, the server competition will be very interesting. It's kind of a unique package for a server, which such a powerful GPU, but that has advantages for some compute types too of course.

Wait max 2 years when the AWS contracts expire

Apple has many different types of data centers.

Some are actually hosted in a cloud provider like Google, Microsoft, or AWS.

But they also have a fair amount of their own physical data centers, and I would not be surprised to find that they start filling them out with Apple Silicon hardware.

And they might roll out a lot of services on AWS using Apple Silicon hardware, because AWS has recently made available actual Apple hardware in some of their regions. I think this could potentially be a precursor, but this is just my own personal hunch and I have no information outside my own brain towards this end.

It depends on how the laptop designed to cool it.

> It's not even interesting that the M1 is "slightly" beaten by a Mac Pro's Xeon, because _nobody is doing raytracing on CPUs._ This is backwards - Nearly all major raytracing workloads today are done primarily on CPUs: vfx, animated film and tv, etc. There are several reasons for this, including memory limits and the lack of coherence in both path tracing algorithms and common acceleration structures. GPU-based trac…

Final renders may be done on CPU for maximum accuracy, but that's not what is being discussed . What's being discussed is desktop workstation rendering. Mental Ray, heavily used in the industry for feature films: GPU accelerated since eleven years ago. Pixar licensed a bunch of GPU rendering tech from NVIDIA in 2015, so that's six years ago. Autodesk Arnold After Effects Chaos V-Ray Weta Gazebo and Manuka ...all GPU…

Mental Ray is used by literally nobody anymore. It was discontinued in 2017. You can't even get a license for Mental Ray anymore.

Pixar didn't license any particular special GPU rendering tech from NVIDIA in 2015; they're just using OptiX and CUDA like everyone else. Pixar released initial GPU support in RenderMan this year, but currently XPU only supports a subset of the full RenderMan functionality. Before that, the only GPU ray tracing they were using internally was on an extremely limited basis for early lookdev workflows. Final lookdev and all of lighting continues to be CPU-only. I likely know more about this particular usage than you do because... I worked on the early internal GPU ray tracing for lookdev stuff at Pixar.

Autodesk Arnold has initial GPU support, but it was only added in the past few years. Most studio usage limits Arnold GPU usage to lookdev; most desktop workflows for iterating continue to be CPU because again... not enough memory on GPUs. SPI Arnold has no GPU support at all. Yes, there are two Arnolds out there.

After Effects is not really used for high-end 3D rendering? Why is it on your list? Did you just do a Google search for "GPU renderer" and throw what you found into a list without actually understanding what each thing is?

V-Ray has had extensive GPU support for many years now, and it probably leading the pack among usage in film/vfx/etc houses. However, most film/vfx/etc places use V-Ray CPU for both iterating on the desktop and for final frames, due to GPUs not having enough memory. V-Ray GPU has seen wide adoption in the archviz world though.

Gazebo is an OpenGL viewer, used in DCC viewports. It's not even remotely close to a final frame renderer. Manuka does not have GPU support whatsoever; the Manuka development team literally published an entire ACM TOG paper on this topic which I guess you haven't checked.

I'm not entirely sure how you put your list together; everything on here is either out of date, misunderstood, or just flat out wrong, and all in ways that are immediately apparent to those of us who actually work in this industry.

Cooling laptops just isn't going to happen. I've never had one with a thermal management system that didn't suck. My current laptop has 3 noisy ridiculously loud fans and it can't cool the processor enough to maintain a sustained load at maximum speed. All I have to do to watch it nearly melt itself down at 93 °C is run make all in some project's directory.

If you're plugged in all the time, lower TDP is nice but not critical. And if you live in a cold country, you have to heat up the house six months per year, TDP is just heating with a computing side effect.

> And if you live in a cold country, you have to heat up the house six months per year, TDP is just heating with a computing side effect. Except it is still direct electrical heating which is atrociously inefficient.

I'm in Quebec (Eastern Canada). Most of the electricity is produced from hydraulic power (dams) up north, while cities are in the southern part of the province. Most houses are electrically heated (especially those built after 1970). Production from water turbines is very efficient. Transmission losses are about 30%, because of the distance (> 1500km). Heating itself is 100% efficient, no moving parts, no maintenance. In this context, heating with a baseboard or CPU makes no difference.

Mental ray is no longer heavily used in the industry for feature films: it hasn't been since ~2013 (when Arnold came around). After Effects doesn't really belong on this list? Gazebo is a preview renderer explicitly designed for GPU use, it's not designed for accurate lighting or material look. Manuka is not GPU accelerated (it used to be when first written, but it wasn't worth it given complexity of build setup for…

> Mental ray is no longer heavily used in the industry for feature films

Mental Ray really isn't used anywhere. It sort of died like more than a decade ago.

Honestly, I used it back in 2003 in the VFX industry, but not since.

You have to be mistaken here. No one uses Mental Ray that I have heard of in production in the last decade. Probably someone does, but not anyone serious.

Autodesk doesn't even sell licenses of Mental Ray and I believe you will find it hard to buy them from NVIDIA as well: https://www.autodesk.com/products/mental-ray-standalone/over...

Are you thinking iRay? Still made by NVIDIA and uses GPU acceleration.

The default renderer in Maya, 3DS Max is Arnold these days, others use V-Ray, RedShift, Octane, RenderMan, etc....
