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.
PS My work desktop died on Wednesday afternoon during the SpaceX SN10 flight. I rushed to my local computer store to replace it. Out of the entire store, only 2 motherboards models with Intel's LGA1200 are in stock. All the other motherboards on the shelf were for AMD.
I picked the i5 10400f as it's under deep discount. I asked around and everyone agrees that Intel is competing only on price point right now.
- nullifidian 6y agoIs it a backport? I read somewhere that it's a continuation of Skylake evolution and not a new architecture.
- imajoo 6y agoAccording to the article, "The new generation Rocket Lake is the combination of two different backported technologies. Intel took the Sunny Cove core from 10nm Ice Lake, and re-built it on 14nm, calling it now Cypress Cove. Intel also took the Xe graphics from 10nm Tiger Lake and re-built those on 14nm, but these are still called Xe graphics." So, yes, it appears to be a backport.

- guardiangod 6y agoRocket 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-desperation-on-display-with-rocket-lake/ 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 based on the process too, and a lot of the architectural gains are due to the added transistor counts. If you backport a CPU you lose the efficiency of these new transistors so the energy use goes up and the clocks likely go down as well. Cores take up 2x the size, or at least a lot more than the older core did on the older process, so costs go up too. You can either cut out bits of the core and lose performance or eat it on area and therefor cost. Backporting a design not made for portability isn’t a lose/lose proposition, it is a lose/lose/lose/lose proposition. But Intel is desperate so…
- dralley 6y agoGrudge or not, it's not like he's been wrong the last few years. Turns out all the negativity is well justified...
- Firehawke 6y agoYep, he's been saying the sky was falling for some time, and it turns out he was pretty accurate in his statements on Intel's problems. This review makes it clear that unless Intel magically gets a process improvement they're entirely screwed. This is precisely the same kind of design issue that hit with the latter end of the P4 era, where thermal limitations were so severe that they were crippling the chips. I'd have to do some digging, but I absolutely remember reading an interesting set of benchmarks that made it clear that you were 99% likely to thermally throttle those P4s even with proper thermal paste and an improved high-end heatsink/fan.
- dragontamer 6y agoAre they really? AMD will make gains for sure at this rate, but TSMC can't serve the whole market. Intel owns fabs, and these rocket lake chips will sell to the mainstream just fine. I expect intel's fabs to be a big asset in these COVID times with sold out computers.
- wtallis 6y agoThis chips really don't seem to be a good use of Intel's limited fab capacity. The CPU cores are substantially larger while offering basically no benefits other than AVX-512 support. It looks like Intel would have been better off pairing the upgraded IO and integrated graphics with their existing, smaller Skylake cores.
- dragontamer 6y agohttps://images.anandtech.com/graphs/graph16535/111160.png https://images.anandtech.com/graphs/graph16535/111160.png Pretty much every Rocket-lake score is faster than Skylake across the board. I'd definitely buy a Rocket Lake over any old Skylake based off of these reviews. Rocket Lake seems a wee-bit inferior to Zen3, but AMD Zen3 is pretty much sold out, so if you need a computer, Intel is still there.
- IanCutress 6y agoIf you read the first page, it'll tell you?
- AuthorizedCust 6y agoWhy didn’t you just go with AMD?
- notatoad 6y agojust 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
- AuthorizedCust 6y agoIn 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.
- Kavenerinds 6y agoAssuming that you're thinking they'd be looking at a R5 3600 ($179.99). For gaming the 10400F ($109.99) is basically on par with the AMD. AMD is only worth it for productivity related task, and only then it's a ~15% performance hit.
- towergratis 6y ago> Why didn’t you just go with AMD? It's out of stock everywhere..
- ZuLuuuuuu 6y agoI think Ryzen 5000 series' stock situation is getting better, both 5600X and 5800X has been consistently in stock in Belgium and Netherlands for about 2-3 weeks.
- GrantZvolsky 6y agoOP is implying the i5 was Pareto-optimal in terms of price and performance.

- chronogram 6y ago> My work desktop died on Wednesday afternoon during the SpaceX SN10 flight. What happened? I’ve never seen a computer die during use.
- capableweb 6y agoSpend enough time in front of a specific computer (or little time in front of a lot of different computers) and you'll eventually come across the same thing. In my (around) 20 years in the industry I've had (mostly laptops) die for various of reasons, most often the motherboard and screen giving out, but also the CPU and harddrives. Happened a few time with desktop computers that been 24/7 under stress as well.

- bflies 6y agoFor better comprehensibility, some Geekbench 5 avgs & another layout: 10700K 11700K single 1,321 1,767 +33% multi 8,821 10,474 +18%
- IanCutress 6y agoGeekbench 5 is skewed because the 11700K uses the AVX-512 unit for the AES test. It scores 4x over previous gen now, and that skews the whole end result.
- jayd16 6y ago>Just overclocking the RAM [..] >My work desktop died [..] Are these related, perhaps? I found the juxtaposition quite humorous.
