10G also means you can have machines using the 10G SFP+ cages that are typically available on 10G switches.
SFP+ has an order of magnitude lower latency than 8P8C RJ45 - which is quite useful if you're doing iSCSI or even NFS, especially if they're diskless systems.

iSCSI over Ethernet does require jumboframes though, as you almost always want to go with 4kB sectors and that's more than can fit in a standard Ethernet frame.

a huge caveat for infinite band at home core driver and hardware compatibility matrices for infiniband are notoriously strict and complex

It is not uncommon for an HPC environment to wait over a year for Intel to publish a certain fix for driver or something that is blocking a major networking or compute upgrade
Mellanox and drivers: a prolific duo even on really common platforms. A few years back my previous employer had more trouble with the firmware than their drivers. To the point where we had calls with a firmware engineer there who seemed excited that it wasn't just an "it's broken" report but instead involved dumps, specific scenarios, etc. Not a bad vendor to deal with. Especially because we were fairly small and other vendors would frequently ignore ongoing issues for months at a time.

Weird brain. They were reporting i3s as better performing CPUs than the 8700k & 9900k at one point in their crusade against Ryzen. Without factoring in price - aka the one legitimate metric you could say an i3 is a good buy on. And this was when the 8700k & 9900k were arguably better buys than the AMD CPUs.

The intel subreddit doesn't allow links from their site, but I don't know if Intel had any say in that.

The real criminal part is their site has some great data. When you want to compare performance of older hardware against newer there's no other great resource. When you want to see if you have something misconfigured and compare each part of your system against the average person who benchmarks there it's a great site too. The data/service they provide is so good that some reviewers were fearful it'd cut into their market share. But the site doesn't capitalize on this stuff and instead keeps doubling down on conspiracy theories.

I used to assume the people running the site were 12-15. The site has been around too long for that to be true at this point.

One hopes Intel's marketing department would be smart enough to tell them to tone it down a bit if they were calling the shots.

There are still some rumors going around that the Rocket Lake numbers are not representative of final performance. Seems that there are both new bios and microcode revisions showing up at the vendors now that are dramatic.

I really hate that both CPU vendors end up pushing out stuff that needs day 1 patches and whose full performance needs to “mature” over its first year, but I guess that’s just the DIY business these days.

I dunno what they are arguing about but tbh I do think AT’s review is more of a preview without the final BIOSes. Zen2’s launch shoulda taught us all that.

Yes I know the retailer hosed up and sent the retail parts out early.

It's explicitly not though, which is why people (including me) were excited for it. It is the same manufacturing technology, but a totally different architecture for the first time for Intel on desktop since 2015. Just like Zen 2 and Zen 3 are on the same node but have large performance differences, a lot of people were expecting big things. As of right now, thats looking unlikely.

Orders were closed for a while, but the other day the page was back up. Wonder if they thought since they'd be fined anyways may as well scalp as many orders as possible.

In 2015, Intel released processors based on the "Skylake" architecture. This architecture was based on a 14nm manufacturing process, and the CPUs were marketed as their 6th generation of Core processors (i.e. the i7-6700K)

They followed this up with "Kaby Lake" in 2016. This was an improvement of their 14nm process, and was marketed as their 7th generation of Core processors (i.e. the i7-7700K)

They followed this up with "Coffee Lake" in 2017. This was a further improvement of their 14nm process, and was marketed as their 8th generation of Core processors (i.e. the i7-8700K)

In 2018, Coffee Lake was refreshed as a 9th generation of Core processors, notably in the form of the i9-9900K.

In 2020, Intel released the "Comet Lake" series, yet another improvement of their 14nm process, and was marketed as their 10th generation of Core processors (i.e. the i9-10900K)

All of these processors use the same architecture - as your manufacturing process gets better, your "yields" get better, meaning you can produce more fully functional processors with the same amount of silicon, and fewer of those processors will have flaws. In one respect, this drives down costs, allowing you to sell a quad-core chip (the i3-10100) as a cheap entry-level part that used to be a high-end part (the i7-6700K).

The maturity of the manufacturing process also means that you can clock the chips higher while keeping them stable, and you can squeeze out a little more IPC every time.

However, these are incremental gains, and are never going to match up against a competitor that's iterating on new designs, which can yield larger jumps in performance. Of course, to research and develop a new design takes a lot of time and money, and a bad design might not be much of a gain at all (ex. AMD's Bulldozer architecture).

___

Rocket Lake, this 11th generation that we're talking about with the Anandtech review, is a new design. Or rather, supposedly the design is based on the Tiger Lake archtiecture developed for the 10nm process, but "backported" or adapted for the 14nm process, probably because Intel doesn't have enough 10nm manufacturing capacity just yet to jump directly into producing desktop parts on top of also producing mobile parts. Using a 10nm design but manufacturing it for 14nm parts theoretically allows them to produce new desktop parts without crowding out their existing 10nm commitments.

Unfortunately, as the performance metrics seem to indicate, that kind of compromise might have resulted in a design that's bad enough as we've seen.

Wow. Thank you for breaking things down like this.

There are advantages to PGA, too. While it's a pain to unbend their pins, it's at least feasible - good luck unfucking an LGA which has taken any damage at all.

The socket not having a mechanism to hold the CPU down is pretty garbage, quite honestly. I don't see why they couldn't do that with PGA.

It's OK that there's parity, but there wasn't for a quite some time, and also, the fact that we can buy the same amount of RAM for the same money is extremely disappointing. The same cash (or even a tiny bit less with inflation) should buy a lot more RAM so many years on.. that's how it always used to be

Edit: thought I'd dig through some old orders.

£85.98 bought you 2x 256MB DDR PC2700 back in 2002, nobody would have been happy paying (adjusted for inflation) £120 in 2012 for 512MB of RAM, even if it was DDR3, and faster

vv Speed isn't the best argument, as speed always increased through generations, whilst price per GB always dropped. All I'm saying is that the added complexity of DDR5 has me worried with regards to price, seeing as trends haven't exactly been favourable

Yeah, but the $70 DDR4 is considerably faster than the $70 DDR3.

You can also get lovely 16GB DDR4 for $60, and $70 in 2012 dollars is $80 in 2020 dollars, so now you're talking faster RAM at the same size capacity at 75% of the price. It's not amazing, but RAM just hasn't advanced as quickly as things like mass storage have.

8/16GB has also proven to be "enough" for desktop users for a lot longer than 1/2/4GB in the DDR3 days did, which is keeping demand for larger capacities down.
