BlankSystemDaemon posted:wait until it turns out that like ARM big.LITTLE, the differently sized cores implement different instruction sets That was a Samsung thing, not an ARM thing. Samsung built an Exynos chip with four of Samsung's "Mongoose 3" ARMv8.0 big cores and four Cortex-A55 ARMv8.2 little cores. But the really big fuckup was software. Samsung shipped Exynos phones with an Android Linux kernel they'd patched to remove a dissimilar ISA sanity check. This check would ordinarily cause Linux to report the least common denominator ISA feature set to applications, so that nobody would think it was safe to use an instruction that was legal on only some of the CPUs.

My guess is that we will see it used in practice a bit like with the mobile cores, sort of as a power state thing. Low load: small cores used; high load: big cores used. Dark silicon's a bitch

It appears the weird anime avatar leaker squad has hit on somethin tasty. Sapphire Rapids, Intel's much anticipated next server product that is gonna launch PCIe 5 and DDR5 later this year and a huge amount of big iron clients are waiting on, is a 4 chiplet MCM. https://t.bilibili.com/488021238176910289 This had been rumored a lot, but appears is true. The rumors were that each chiplet (or "tile") had 15 cores with 1 core per tile disabled for yield reasons. The rumors also talked about HBM2, but I don't see any on the package as far as I can tell. It might be 3d packaged under the core tiles, but that doesn't sound very thermally doable.. There is an Altera Max 10 FPGA on board as well, which is interesting.

I swapped my 8700K to a 9900KF (costing about £100 after flogging the 8700) and the main benefits were seeing more cores/threads in HWMonitor (whoop) and stopping myself spending £600-700 on a new motherboard and 11700K this summer, which I'm sure will also make little or no difference in 1440p gaming.

So, weird question but does anybody know if the cpu cooler mounting holes on a z490 board are the same as a z270 board? Wondering if you be able to swap 2 systems around, with an older one (7700k) going into a MSI trident pre-built and the newer one (10700k) going into a nr200 case.

Wondering if you be able to swap 2 systems around, with an older one (7700k) going into a MSI trident pre-built and the newer one (10700k) going into a nr200 case. probably yes, Intel hasn't actually changed the mounting pattern since LGA1155, all coolers with a standard mounting pattern use the same hole spacing/ILM height/etc. it is possible the Trident uses a non-standard mounting pattern though, since it's a pre-built, but it will probably work. If there is any information online about people who are swapping other standard coolers onto the Trident then that will be fine. note that depending on what you're trying to do, the actual PCB layout may not be exactly identical, so if there is some type of integrated cooler to get the size down in that chassis and it doesn't have tubes/etc for flexibility, then you may not be able to swap out the whole motherboard, because the socket wouldn't be in the right place. thin-itx standardizes the socket location but regular ITX (assuming the Trident is even a standard ITX) does not. but in answer to your direct question yes, the socket and mounting holes themselves are standardized.

Look up the current specs for your cooler and check its socket compatibility lists. But generally it should, LGA1200 uses exactly the same mounting positions as LGA115x.

The mounting holes are the same but some itx z490 boards have compatibility issues with certain AIO coolers, the block contacts some of the surrounding objects. I think the ASUS and Asrock have trouble while MSI and Gigabyte are ok. I believe it’s mentioned in this video. https://m.youtube.com/watch?v=TmgR9qNGKlk

Thanks for the advice, everybody. So the trident x uses it's own cooler design but the motherboard seems to be an In that case, if the mounting holes haven't changed, I presume the proprietary CPU cooler will probably fit on a Z270 board in terms of actual mounting, but that the clearance from mb heatsinks / ram positioning and such will be the main issue. Edit: Hmmm maybe not. Looking at the picture of the ports here from the Tom's review: https://cdn.mos.cms.futurecdn.net/9dKE3PEZVYrJPKgmeBWd2Q-970-80.jpg.webp does not look like how it should lineup with the actual board itself here: https://www.amazon.com/MSI-MEG-Z490I-Motherboard-Thunderbolt/dp/B0876H2R85 Looks like it is proprietary in which case it might not be possible to swap. E2: Yeah, the io is different in this pcmag review, too: https://i.pcmag.com/imagery/reviews/04bOQwneshnbkN7YcktT5mL-4.fit_lim.size_960x.jpg Looking like a strong no-go. Ah well.
