i7-10700K to the i7-11700K Single thread floating point: +19.0% Multi-thread floating point: +19.5% Single thread integer: +13.0% Multi-thread integer: +7.3% Jesus. Just overclocking the RAM for the 10700k would give a similar performance increase. Along with 291W, this 10nm->14nm backport is not working out well for Intel.

Why didn’t you just go with AMD?

just a guess, but if he went to the store looking for an LGA1200 socket motherboard, he wasn't planning on purchasing a new CPU as well

Is it a backport? I read somewhere that it's a continuation of Skylake evolution and not a new architecture.

Rocket Lake was designed for 10nm, but Intel couldn't get 10nm to work, so they backport Rocket Lake to 14nm. https://semiaccurate.com/2020/10/29/intels-palpable-desperat... Just filter out Charlie Demerjian's grudge against Intel. Companies don’t backport because a core is designed for a process. It’s efficiency and architecture is based on the transistors that it will use from the design start, caches are sized bas…

Grudge or not, it's not like he's been wrong the last few years. Turns out all the negativity is well justified...

Isn't such a thing necessary as we see US presidents falling for (deep)fake media? Is there a privacy-respecting solution that you prefer?

I'm just going to say, if you don't think this _isn't_ going to be massively abused - take a look at what the CCP, or any authoritarian regime does really, to silence dissent. Don't have a good enough social credit because you shared an opinion somebody doesn't like one too many times? Intel and Microsoft will just remotely brick all your devices. > Is there a privacy-respecting solution that you prefer? Yeah, it's c…

This is a no-win situation, really. All of those arguments can be made about deepfakes too.

Price is the biggest factor. You can get 10 cores with Intel for cheaper than 8 with AMD, plus with Intel you get integrated graphics as well which is really important right now considering the GPU shortage. Also, Intel allows virtual GPUs for virtualization in QEMU which AMD won't do.

If I wanted more than 8 cores, the 12-core ryzen 5900X is $549, can you really get an intel 10-core cpu for the same price, or within 50 bucks plus or minus, that performs better? I'm seeing the i9-10900K for $467, but in terms of dollars/performance per core I think it's still behind the ryzen which costs $82 more. https://www.techspot.com/review/2132-amd-ryzen-5900x/

I wouldn't look at the 10900k trying to "save a buck" on the high end. Instead the 10850k which is, for most purposes, just a 100 MHz slower 10900k can be found on sale for 350$. Higher availability, and prices that meet or are below recommended MSRP.

I'm just flabbergasted that Intel has Thunderbolt support integrated into it's mobile chips, but on desktop it's business as usual, left to motherboard vendors to implement Thunderbolt themselves with the normal slew of add-on chips. Super frustrating that desktop users can't expect modern connectivity. It should be on the chip, like mobile. Notably, one can take any old TB4 cable, connect two modern Intel laptops, a…

Is the 20Gbps on Rocket Lake’s integrated USB 3.2 Gen 2x2 “close enough” to TB4’s 40Gbps?

You have to give whomever came up with 14nm process. Despite being super old it's still somewhat competitive. It's crazy Intel can't fix their process. They make more cash than amd, nvida etc. They make more cash than tsmc.

Intel's 14nm process is, in terms of dimensions, closer to TSMC's 10nm, and their 10nm is only slightly larger than TSMC's 7nm: https://fuse.wikichip.org/wp-content/uploads/2018/02/iedm-20... That being said they really need to step up their game or else they'll be bleeding market share for years to come.

I give the people working on 14nm a ton of credit for being able to squeeze out as much performance as they have. As long as big datacenter customers worry about AMD's supply chain that will probably keep them from switching en masse, though the big TSMC plant coming on line might go a long way towards alleviating those concerns.

I see nothing in this review that would make me choose the Intel part over a Ryzen 5800X.

... or the 5600X (probably equal perf but cheaper / lower power) or the 5900X (about the same price if you factor in power supply + cooling, still lower power).

In his last paragraph, he said he bought a new processor. Or at least, he suggested a purchase by referring to its discount using present tense.

Beaten by the 5800X in almost every test, unless AVX512 was used. Given the 7nm shortage at TSMC, Intel might still beat it in price / availability.

For 5600X/5800X, availability is fine now. They’ve been in stock at amazon for a few days continuously. 5900X and 5950X on the other hand.. good luck.

Either I had really bad timing or bad luck, but somehow I am ending up with Intel even though I really wanted to switch. Around 2012 I bought a 4-core Core i5 and after some basic upgrades (max RAM to 32GB and a good SSD) it had more-than-acceptable performance for my work until mid-2018. Even when I dabbled with Machine Learning I borrowed a 1070 from my office and was plenty to run my tasks. Around end of 2018 I st…

> a basic motherboard is 300€ A 'basic' motherboard two weeks ago was the same as it is today, a low-end B550, and can be purchased for under 100€. The 10900 trades blows with the 3900x, particularly for multi-threaded, workstation-type workloads where the AMD part pulls ahead with its two extra cores. And the 3900x can be had around the same price as a 10900. So your "honest account" comes off as a little disingenuo…

I paired up a 5950x with a $200 TUF 570 board - a middle of the road offering. One thing to consider is the BIOS version of the motherboard. The Asus one had a sticker with the build version, and what they were stocking in Microcenter was just new enough to support zen3 OOTB. A better board would allow for BIOS flashing without the CPU, and a few folks have struggled with that first flashing. Check the version first.

The threadripper boards are starting at $400 for the current generations. I regret spending what I did on the first generation boards, as they dropped support for them on the third generation. I'm waiting to see a zen3 series threadripper before I'll replace my old 1950x. The even older 3930k i7 was able to keep up on single threaded processes... which surprised me. Funny it really took 10 years before I got that wow factor again. The number of cores that I'd consider 'normal' has certainly gone up. Think the 3930k was around $600 in 2011, the 1950x around $800 in 2017, and the 5950x at $800, so that price point has not changed much. The first two were picked up at launch date, the last was a paper launch that took till January to find.
