>ludicrous amount of power and cooling >big honking machines Buy an all-in-one water cooler for the CPU https://pcpartpicker.com/product/2PFKHx/arctic-liquid-freeze... It's easy to install and you have a quiet, well-cooled CPU.

AIOs aren't a great option for users who want to set it and forget it. Even the best ones lose fluid to sublimation and/or start leaking after a few years, which is why there's still a market for coolers like the NH-D15.

Citation needed. "The best" AIO coolers shouldn't have issues with fluid lose in a meaningful way that impacts performance.

Likewise, I'm not aware of any widescale issues with AIOs leaking. This seems like just as much of a problem as regular CPU coolers that need to have dust removed (i.e., not a problem).

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…

IMO driving down power consumption should still be a goal even for desktop machines. It means that the overwhelming majority of users get cooler, quieter, less bulky machines, while the fringe who need raw power at all costs can overclock to the moon if they really want to. This also pushes more "desktop like" performance to both ultraportable and reasonably portable laptops, allowing these machines to fully replace…

It is the goal (after all more efficiency also means fitting more powerful cores into the thermal envelope) but given the choice most desktop users would be fine with "just a bit bigger box" rather than sacrifice performance for the price.

Measured as one percent lows and again, most GPUs under most Conditions simply don't saturate PCIe enough for that to make a difference. Der8auer and GamersNexus on youtube have plenty of examples.

1% lows in a given benchmark isn’t really measuring stutter in practice, what you want is percentage of frames that don’t finish in time. If once a minute you miss 4 frames in a row that’s noticeable even if everything else is rock solid. The thing is people adjust their resolution/settings to reach acceptable FPS, thus it’s fairly GPU independent. What matters is rendering volatility as assets are loaded etc.

That metric is irrelevant now that we have adaptive refresh rates. You don't really "miss" a frame anymore. 1% low is now the correct metric.

All all the M2 variants just Apple going down the binning path because of yields?

M2, M2 Pro, and M2 Max are different dies; they aren't binned versions of the same die. Apple showed "photos" of the dies and you can see they are different sizes with different stuff on them.

Are their yields actually that good, then? Are some of these chips massively underclocked? Do they add extra cores and cache for redundancy? Or maybe they have no idea, and TSMC delivers only chips that pass QA. For as big as Apple is, TSMC is in the stronger negotiating position.

Wait, a $7000 computer doesn’t come with a discrete GPU?

It's not just that it doesn't come with a discrete GPU. Apple Silicon doesn't support discrete GPUs to begin with. As far as I understand it—and this is just from watching Apple's presentations on the architecture—the lack of a discrete GPU is a big part of how the Apple Silicon machines achieve good performance per watt. Instead of having discrete RAM or a discrete GPU with its own VRAM, all of the RAM is accessible…

Desktop pcs requiring a ludicrous amount of power and cooling is absolutely problematic. The amount of people willing to put up with big honking machines is dwindling.

AMD and Intel are jacking up the default power settings to absurd levels because it gives marketing bigger numbers to to throw around. You can drastically reduce the power you supply to desktop chips with BIOS settings. You'll generate far less heat, can use a smaller power supply and form factor, while still getting great performance. If Intel/AMD get to a level where their chips rival M1/M2 while power throttled, t…

I have 120W TDP chip on default settings and it only ramps up to the max in rare cases like compiling shaders for RPCSX3

> If Intel/AMD get to a level where their chips rival M1/M2 while power throttled, things get interesting.

For laptop users, maybe. For desktop extra 40W literally doesn't matter.

Because Workstation, by a lot of people's definition, are suppose to be the power hungry in exchange for absolute performance?

You're doing it too. You're assuming how someone would define a workstation, you're assuming that definition includes it being power hungry. A workstation can be a single core, 256MB RAM, 1 watt SBC. It can be a 96 core, 2TB RAM, 1 kw beast. It can be anything in between or even outside of that range. I'm not saying everyone cares about power consumption, but several people here seem to be saying that no one does, an…

> A workstation can be a single core, 256MB RAM, 1 watt SBC.

No. Words have meanings. Workstation does not mean that.

Is it? Why? My machine is entirely silent on normal operations (Zen 3 5600X and RX 6700). All the fans, on both GPU and CPU are stopped in desktop usage. And it doesn't obviously eat that much power (my monitor probably eats more). The only moment I could hear them is if I play games. And then I have headset on, so I can't hear them. I really couldn't care less if it ate twice the amount of power when playing games.

> Is it? Why? Because, while gaming, the vents in my case blow air at over 40 degrees Celsius, and that heat has to go somewhere. Absent a setup that can put the case several meters away from me, that "somewhere" is on top of me.

Flip it 180 degrees ? Cases are designed to blow the air into the back, not to have back facing the user...

Comparing the OpenCL GeekBench score is unfair. "More popular"? I don't really think so. Anyway of course it's going to be slower than a machine with more then two times its number of cores.

Why isn't it fair? NVidia GPUs are notoriously terrible at OpenCL.

I went with the NH-D15 when I built my 5950x desktop. I've never fiddled with liquid cooling, and having to locate a radiator seemed like a pain. I very much hope not to need to touch it again for a decade. After tweaking the fan profile, it's silent most of the time. Of course, it does make it kind of a pain to remove my GPU because it's so bulky; I need to use a shim to reach the PCI-E latch.

My 120W 7800X3D only managed to heat that monster to 70C. I should probably bump the thermal profile to spin to max only around 80C...
