50% slower than the absolute best of class NVIDIA discrete GPU offering that consumes massively more wattage is hardly a damning statement.

Most consumers don't care about wattage on a desktop, and when you compare the prices they are similar and it loses.

Kind of. I did a quick comparison this morning between a MacPro and a similar high-end Dell workstation and the prices are similar.

I do. I don’t like noise, or having my office heated in the summer, or the cost of hundreds of watts.

Slightly ironic, coming from someone who claims to use a tokamak to heat a teapot!

Queue the "But power consumption..." as though it makes fuckall difference on a workstation.

Perhaps not to you but to me it matters a lot.

I live in a country where it gets very hot in the summer. I prefer to keep my environment cool without needing AC. Unfortunately I have found that is not possible to do with my beefy Dell workstation that consumes in the 1kW range thanks to the Intel CPU and Nvidia GPU.

It isn't just a feeling but a hard fact that my thermostat can confirm that running my Intel workstation puts my office up to uncomfortable temps. No such thing happens with my M1 Ultra Mac Studio running with a third to a quarter less power consumption.

Perhaps I am alone in this but I dislike having to use AC to cool my office when I can just not make it so damn hot in the first place. It is all just a waste of energy and energy isn't free.

If it's not an issue for you then fair enough buy a 1kW+ Intel/Nvidia system but to say "it makes fuckall difference on a workstation" is disingenuous.

I find the article quite informative. Yes, M2 and the other chips are completely different products with different goals. If one wants to say that something completely trumps the other, it will be wrong. But here is what is visible: The M2 core is probably in the same ballpark as Zen 4 core, likely a tiny bit below. That may become very tiny if Zen 4 core runs at lower frequency to equalize the power. This doesn't ac…

Apple's GPU performance is what makes me sceptical about their gaming related advertising. Sure, you can do 1080p gaming with the highest SKU, but you're paying through the nose if you bought an M2 to play games.

It seems strange to me for Apple to advertise something they haven't exactly mastered yet on stage.

Maybe they have some kind of optimization up their sleeves that will roll out later? I can imagine Apple coming out with their own answer to DLSS and FSX2 based on their machine learning hardware, for example. On the other hand, I would've expected them to demonstrate that in the first place when they shoed off their game port toolkit.

The M2 has been a bit underwhelming in general through all of its iterations: Apple jumped into such a lead with the M1 [1], so it was disappointing when they slowly iterated while Intel and AMD have made enormous strides catching up. Everyone keeps citing TDP, but given that we're talking about desktops that just isn't a huge factor. Having said that, the 7950X was released late February, and the 13900KS was release…

With power in city downtowns (eg San Jose) at $0.50+/kWh it’s definitely becoming a huge factor. My Mac uses almost an order of magnitude less power than the PC and I keep the PC powered off.

> My Mac uses almost an order of magnitude less power than the PC and I keep the PC powered off.

Either you are not measuring power consumption correctly, or there is something very wrong with your PC.

They announced MetalFX for their upscaling tech last year and by all accounts it works well if developers take advantage of it.

The article reports that the M2 Ultra is basically even with a 4060 Ti in OpenCL compute which they refer to as a mainstream card. It is more a notch above entry level. The "best of class" 4090 is actually 2.5x faster. But again, this is OpenCL so who knows how the two compare in a more relevant benchmark.

Regardless, wccftech is far from reliable. IIRC, /r/amd blocks links to the site.

Maybe, but most of these comparisons are based on GPU performance (ie. games). For other workloads like machine learning, Tensor cores on NVIDIA GPUs will blow Apple Silicon GPUs out of the water. The M2 Ultra is 27 TFLOPS. The 4080't Tensor Cores are 48.7 TFLOPS in FP32, 194.9 TFLOPS in FP16, 389.9 TFLOPS in FP8 with FP16 accumulate. (IIRC on Apple Silicon GPUs FP16 performance is roughly the same as FP32.) (There i…

I think the exciting thing with Apple silicone and "AI" is inference, not training. Due to their unified memory, you can potentially have enormous local model inference. That's potentially much more expensive on a PC with a GPU having its own memory.

Apple have an opportunity, if they 2-4x the memory on the entry level devices (not beyond the realms of possibility), to make local inference a thing available to all.

The article does not say if it’s a Mac Studio or Mac Pro. I think that matters. My understanding is that there is no TDP on Apple Silicon, and that it has a lot of runway in a less constrained thermal environment like the new Mac Pro vs Mac Studio. While I’m still surprised they didn’t put a second Ultra in the Mac Pro, I’m betting there’s a wider delta than people imagine between the two form factors.

The Mac Studio doesn't throttle so there is no extra headroom for the Mac Pro.

> The M2 GPU is in the same league as a 300$ mid-range nVidia card It still has the advantage of a much larger memory pool. I did a quick comparison exercise - I priced two workstations with similar configurations, one from Dell, the other from Apple. While there are x86 (and ARM) machines that'll blow the biggest M2 out of the water, the prices, as far as Apple can go, aren't much different. https://twitter.com/0xDE…

> It still has the advantage of a much larger memory pool.

Why do you think NVIDIA doesn't "just add" "more memory"? To its $40,000 H100s, which top out at "just" 80GB?

The answer isn't price segmentation.
