I'm currently running on a 6C/12T Xeon 2430v2 that I got for ~68 USD off Aliexpress, combined with an OEM (read: knock-off, unbranded) Chinese LGA1356 motherboard for ~58 USD, and two sticks of 8 GB DDR3 ECC RAM for ~31 USD per stick. The Radeon RX 560 was also just ~51 USD, and the whole build came in at just over 450 USD. (I'm still slowly accumulating parts for a Ryzen rig anyway because there's no upgrade path for this, as much as I love it.)

Palladium posted:I assumed you bought those parts some time back? Because paying those prices now is a ripoff. I'm in the Philippines, so there's a significant mark-up for shipping (and avoiding our regular postal service), but it was still cheaper than buying retail as far as I could tell. For example, I also bought an Athlon 200GE for 2,510 pesos (about 48 USD) two weeks ago, and it would have cost 3,600 pesos (about 69 USD) in a brick-and-mortar store.

are there are any rumors or even known news about the low-end/budget scale for desktops, or can we expect that something like the Pentium G4560 is still going to be the thing for a while longer.

Mr.Radar posted:They probably won't release a new low-end line until they get a new architecture out and work through their manufacturing backlog. Have you taken a look at AMD's offerings in that market segment lately? If you only need a dual core desktop CPU you can grab an Athlon 200GE for $55 and an inexpensive B450 motherboard. Or grab a Ryzen 2200G for $80 if you want to step up to quad core with an iGPU that crushes Intel's offerings. Those will also give you a clean upgrade path to Zen 2 (and maybe even Zen 3) in the future (while there's rumors Intel's planning to change sockets again with their 10 core launch...). That actually is precisely what I'm doing - I got an Athlon 200GE and a B350 motherboard, with an intention of moving up to a 3400G or whatever AMD has to offer on the AM4 platform by next year. I was just curious if there's been any movement from Intel in this regard.

https://www.techpowerup.com/260130/intel-scraps-10nm-for-desktop-brazen-it-out-with-14nm-skylake-till-2022quote:In a shocking piece of news, Intel has reportedly scrapped plans to launch its 10 nm "Ice Lake" microarchitecture on the client desktop platform. The company will confine its 10 nm microarchitectures, "Ice Lake" and "Tiger Lake" to only the mobile platform, while the desktop platform will see derivatives of "Skylake" hold Intel's fort under the year 2022! Intel gambles that with HyperThreading enabled across the board and increased clock-speeds, it can restore competitiveness with AMD's 7 nm "Zen 2" Ryzen processors with its "Comet Lake" silicon that offers core-counts of up to 10.

My general impression of Zen2's various boost mechanisms is that they maximize performance enough that there's often very little room for squeezing out more via a manual overclock Does a similar situation exist with Intel's chips, either on their current generation or what we can expect from Comet Lake?

while I get that Intel has iGPUs in a lot of their CPUs so that you can run an office machine without needing a dedicated GPU, what is the use-case for putting an iGPU in something like an i5 or an i7, where you wouldn't expect that someone would get a quad-core (or more) just as an office/browsing machine, but at the same time, any gamer/enthusiast/content-producer is going to get a dedicated GPU anyway, especially since the Intel iGPUs are not powerful enough to really be a stand-alone solution the way AMD's APUs are/were intended to be. I guess it would make sense for laptops, but I checked and even something like an i5-6600k for the desktop has an iGPU. Is it just a production thing where it's not worth "removing" the iGPU?

This is going to segue into a more general question about technology and manufacturing: As I understand it, and I could be dead wrong, the basic idea is that you have a wafer of silicon, and then the pattern/design for a chip gets "etched" onto the silicon by a process that, by now, is EUV, and then the wafers gets cut-up into "dies", and each die represents a chip. All of these chips are made from the same pattern, but each individual chip is not going to perform the same way, and that's what gets branched off into different SKUs: some chips will have bad cores so you sell them as less-core CPUs, some will clock better than others so you "bin" them into a different SKU with a higher base/default clock, and so on. Is that about right? And if what I'm following correctly what y'all are saying, the desktop CPUs and the laptop CPUs are all from the same manufacturing process, and separating them into each of these two categories is just another "binning distinction" (my term), where you pick the chips that consume low amounts of power (is that what "low leakage" is?) and use them for laptops, and then you pick the chips that consume (relatively) lots of power and use them for desktops (since you can always throw more cooling at a desktop CPU). And then, HEDT CPUs and server CPUs are all from the same manufacturing process themselves, where you take pick the chips that consume low amounts of power and use them for servers (since servers need to be relatively cooler, since they rely on passive cooling on a rack), and then you pick the chips that consume lots of power and use them for HEDT. Is that about right? I guess the part that's still blowing my mind is the idea that the laptop CPUs that consume as little as 15W or less is, ultimately, very similar if not the same as the desktop CPU, except maybe with some internally programmed limiters to keep it that way? EDIT: I guess another question would be if the above paradigm that I'm describing is specific to Intel, at least as far as SwissArmyDruid suggesting that the desktop/HEDT CPUs are all just cast-offs. gradenko_2000 fucked around with this message at 15:22 on Jan 16, 2020 |

so if Rocket Lake is expected to have Xe graphics, and that very early leak from Tiger Lake, which does have Xe graphics, suggests performance that's comparable to a Ryzen APU, doesn't that create a situation where any non-F Rocket Lake CPU is going to be able to drive graphics at a level similar to, say, an Athlon 3000G or a Ryzen 2200G? That seems kind of interesting, I'm kinda thinking from the perspective of even office computers with a Rocket Lake Pentium having a decent iGPU. Meanwhile Comet Lake on the desktop is still going to be using UHD, right?

The low-end pricing seems... not great? 64 USD for a 4.0 Ghz 2c/4t Pentium or 122 USD for a 4c/8t Core i3 is going to be tough to justify against the Athlon 3000G, the 1600 AF, the 3100/3300X, and the 2400G / 3400Gs.

the dual-cores were all called Core 2 Duo Exxx the quad-cores were all called Core 2 Quad Qxxx there was one SKU that was a dual-core, but was sold under the Core 2 Extreme branding, which was the X6800 all the other Core 2 Extreme chips were designated QXxxx and were quad-cores (there was also four Core 2 Solo SKUs, the U2100, U2200, SU3300, and SU3500, which were single-core CPUs)

Scientist Al Gore posted:What comes after Comet Lake for the desktop? Tiger Lake? Rocket Lake - it's still going to be on 14nm (however many pluses) and is expected to still be compatible with the same LGA1200 socket that Comet Lake will use. I think the other big thing about it is that Rocket Lake is supposed to be using the new Xe iGPUs (which Tiger Lake will also use, but Tiger Lake is going to be mobile-only) After Rocket Lake is supposed to be Alder Lake, which is going to be 10nm on desktop

Cygni posted:fascinating stuff is it A Thing for people to underclock (undervolt?) or otherwise restrict their systems from running full clip, for the purposes of keeping temperatures in check, as long as they don't mind the performance hit? specifically for Intel, is that something that'd require an unlocked CPU, or is that something that you could do from the motherboard? I guess where I'm coming from is that, having watched that Gamers Nexus video, the thing that stood out to me was this notion that if only the motherboard would run the CPU according to Intel's specs, then the CPU would keep within the advertised TDP, which then means if your cooler is only as good as that advertised TDP (and I'm acknowledging that this is rather fuzzy), then that's how you can keep a CPU happy with a dinky little cooler (again, provided that you don't mind the performance hit). ___ Another question: if the T-version of a CPU can be made to violate its own TDP limits via the motherboard, is that why T-versions are sold to be more expensive, rather than less, because otherwise people would just buy the T-version and then remove the TDP limits and experience a CPU that's as good as a non-T? Also, doesn't this mean that if you bought a T-version CPU, specifically because you want a CPU that doesn't run so hot/doesn't consume so much energy, and then your motherboard has TDP-busting turned on by default, you're kinda getting screwed if you don't know that this is a thing that you need to check?

DrDork posted:T-versions are more expensive because they can hit higher clocks at a given voltage than others--the entire point is that then you can run them super light on power and still get decent performance. It's effectively a more efficient chip, so you get to pay a premium for that. The leaky "just shove more power into it" silicon is what you get for normal desktop chips. By this, you mean that, even though T chips are clocked lower than non-T, if you took a non-T chip and set it to the same clock and the same voltage as a T chip, it wouldn't be stable?

In pretty much all overclocking videos I've seen that work with liquid nitrogen, people seem to build like a receptacle on top of the CPU, and then they have a cooler or a tumbler full of nitrogen, and then just pour the stuff straight onto the CPU. Obviously the stuff evaporates, so you have to keep pouring more and more in over time, and it's a temporary thing. out of curiosity, is there something like a closed-loop cooling system that uses liquid nitrogen? is that even possible?

so you buy a locked CPU, and decide to pair it with an H410, B460, or H470 motherboard, since you don't need the overclocking capabilities of a Z490 except you're leaving performance on the table because your memory speeds are capped/can't be tuned as tightly so it pushes you towards wanting a Z490 board instead except pairing a locked CPU with an overclocking board is dumb but getting both an unlocked CPU and an overclocking board is also that much more expensive but kneecapping your memory by using a non-Z490 chipset is also dumb is that about right? seems bad
