Getting bitten by Intel's poor naming scenes

This isn't that bad if you compare it to the USB naming fiasco... but yeah, definitely a problem in the tech industry for a long time.
sofixa•1h ago
Not really comparable.

With Intel's confusing socket naming, you can buy a CPU that doesn't fit the socket.

With USB, the physical connection is very clearly the first part of the name. You cannot get it wrong. Yeah, the names aren't the most logical or consistent, but USB C or A or Micro USB all mean specific things and are clearly visibly different. The worst possible scenario is that the data/power standard supported by the physical connection isn't optimal. But it will always work.

I don't know what "always work" means here but I feel like I've had USB cables that transmit zero data because they're only for power, as well as ones that don't charge the device at all when the device expects more power than it can provide. The only thing I haven't seen is cables that transmit zero data on some devices but nonzero data on others.

dtech•14m ago
I don't think those cables are in spec, and there are a lot of faulty devices and chargers that don't conform to the spec creating these kinds of problem (e.g. Nintendo Switch 1). This is especially a problem with USB C.

You can maybe blame USB consortium for creating a hard spec, but usually it's just people saving $0.0001 on the BOM by omitting a resistor.

I can't find a USB-C PD adapter for a laptop that uses less than 100W. As a result, I can't charge a 65W laptop from a 65W port because the adapter doesn't even work unless the port is at least 100W.

It does not always work.

seszett•22m ago
For this specific issue I'm surprised, I have used all kinds of USB PD chargers for my laptops and all of them but one are less than 100W, with no problem at all.

The ones I use most are 20W and 40W, just stuff I ordered from AliExpress (Baseus brand I think).

zx8080•7m ago
I've noticed that GAN PD's 100w and 65w adapters output is actually less (both do not charge my laptop) than lenovo 65w charger (the one with a non-detachable usbc cable). Cable does not matter, tried with many of them including ones providing power from other chargers.

It seems totally random, and you cannot rely on watts anymore.

I don't think the port names is what they were referring to.

The actual names for each data transfer level are an absolute mess.

1.x has Low Speed and Full Speed 2.0 added High Speed 3.0 is SuperSpeed (yes no space this time) 3.1 renamed 3.0 to 3.1 Gen 1 and added SuperSpeedPlus 3.2 bumped the 3.1 version numbers again and renamed all the SuperSpeeds to SuperSpeed USB xxGbps And finally they renamed them again removing the SuperSpeed and making them just USB xxGbps

USB-IF are the prime examples of "don't let engineers name things, they can't"

While not disagreeing, I'd ask for a proof it's not a marketing department's fun. Just to be sure.

Engineers love consistency. Marketing is on the opposite side of this spectra.

Email them, address is in the guidelines.

I work in CPU security and it's the same with microarchitecture. You wanna know if a machine is vulnerable to a certain issue?

- The technical experts (including Intel engineers) will say something like "it affects Blizzard Creek and Windy Bluff models'

- Intel's technical docs will say "if CPUID leaf 0x3aa asserts bit 63 then the CPU is affected". (There is no database for this you can only find it out by actually booting one up).

- The spec sheet for the hardware calls it a "Xeon Osmiridium X36667-IA"

Absolutely none of these forms of naming have any way to correlate between them. They also have different names for the same shit depending on whether it's a consumer or server chip.

Meanwhile, AMD's part numbers contain a digit that increments with each year but is off-by-one with regard to the "Zen" brand version.

Usually I just ask the LLM and accept that it's wrong 20% of the time.

>"it affects Blizzard Creek and Windy Bluff models'

"Products formerly Blizzard Creek"

WTF does that even mean?

7bees•7m ago
Intel doesn't like to officially use codenames for products once they have shipped, but those codenames are used widely to delineate different families (even by them!), so they compromise with the awkward "products formerly x" wording. Have done for a long time.
ocdtrekkie•1h ago
In fairness, the author should've known something was up when they thought they could put a multiple year newer chip in an Intel board. That sort of cross-generational compatibility may exist in AMD land but never in Intel.
mort96•17m ago
I mean sure, that would seem suspicious. But not suspicious enough that I'd likely have caught the problem. It's not that far fetched that Intel may occasionally make new CPUs for older sockets, and when Intel's documentation for the motherboard says "uses socket FCLGA2011" and Intel's documentation for the CPU says "uses socket FCLGA2011", I too would have assumed that they use the same socket.
tomcam•32m ago
How dare they accuse Intel of any kind of naming scheme at all. Everyone who’s anyone knows it’s an act of stochastic terrorism.
7bees•11m ago
It has pretty much always been the case that you need to make sure the motherboard supports the specific chip you want to use, and that you can't rely on just the physical socket as an indicator of compatibility (true for AMD as well). For motherboards sold at retail the manufacturer's site will normally have a list, and they may provide some BIOS updates over time that extend compatibility to newer chips. OEM stuff like this can be more of a crapshoot.

All things considered I actually kind of respect the relatively straightforward naming of this and several of Intel's other sockets. LGA to indicate it's land grid array (CPU has flat "lands" on it, pins are on the motherboard), 2011 because it has 2011 pins. FC because it's flip chip packaging.
