Intel Core i7-11700K "Rocket Lake" CPU Outperforms AMD Ryzen 9 5950X in Single-Core Tests
Intel's Rocket Lake-S platform is scheduled to arrive at the beginning of the following year, which is just a few days away. The Rocket Lake lineup of processors is going to be Intel's 11th generation of Core desktop CPUs and the platform is expected to make a debut with Intel's newest Cypress Cove core design. Thanks to the Geekbench 5 submission, we have the latest information about the performance of the upcoming Intel Core i7-11700K 8C/16T processor. Based on the Cypress Cove core, the CPU is allegedly bringing a double-digit IPC increase, according to Intel.
In the single-core result, the CPU has managed to score 1807 points, while the multi-core score is 10673 points. The CPU ran at the base clock of 3.6 GHz, while the boost frequency is fixed at 5.0 GHz. Compared to the previous, 10th generation, Intel Core i7-10700K which scores 1349 single-core score and 8973 points multi-core score, the Rocket Lake CPU has managed to put out 34% higher single-core and 19% higher multi-core score. When it comes to the comparison to AMD offerings, the highest-end Ryzen 9 5950X is about 7.5% slower in single-core result, and of course much faster in multi-core result thanks to double the number of cores.

I don't believe that for a second. Look what happened when RDNA2, Vermeer, XBOX and PS all launched within a few months, all coming from TSMC's production.
You think AMD wants to repeat that?
Some illiterate people even thinks those launches were paper launches, which is just hilarious and sad at the same time. It doesn't work like that. ;)
2022 sounds right tho, and maybe even Q3, although I'd guess a bit earlier in the year.
I really don't think decoding width is the bottle neck for x86, well at least not now. But stay tuned for Sapphire Rapids(Golden Cove), where at least the front-end is "significantly larger" than Sunny Cove, including an 600 instruction OoO window. I expect this may be to feed more execution ports, but time will tell. A little side note; don't forget ARM requires more instructions to do the same work, so it's not an apples to apples comparison. (no pun intended) I think you got this all wrong, a bigger decoder doesn't require any ISA changes.
Just wait for Sapphire Rapids, and you'll see a much more sophisticated x86 based microarchitecture.
lol, looks like they are doing another bone headed buyback.
lmao, all those buys and the stock dropped down again.
Geekbench tells us nothing, it's inconsistent with a lot of other benchmarks, and the choice of OS makes way too much difference.
Still, every CPU leak is Geekbench, and still I don't know why. Well unless it's all about accessibility.
I mean, if you're going to pose a question, you aren't necessarily going to get an answer you like :-)
AMD users may like CBench, while Intel users may prefer gaming benchmarks, but my question is, who does Geekbench cater to among HW enthusiasts?
Do we really find a substantial amount of those people in HW forums, for instance? I don't think so.
Each click you make on this website kicks off HTTPS AES Decryption, followed by HTML + Javascript Parsing. Every post you have made is inside of a Javascript WYSIWYG GUI, parsed into an HTML form, packaged into an HTTPS Encrypted message and piped to the server. The very stuff that composes the Geekbench suite.
I said that before, but maybe if I say it again with more explicit examples, you'll get what I'm trying to say.
Its the only number they seem to have do what I do ignore them and wait for a production review. Which won't be until the March 2021 time frame.
I don’t think so. Nah, what happened is GB was always used in the context of iOS vs Android because the benchmark would always get updated to make Apple chips look better whenever a new one was released. Then what happened was that people noticed that those absurd numbers where becoming comparable with desktop chips so now it’s used everywhere.
All over the net you'll find "Let's build a render box!", or "Ultimate ITX gaming" kind of guides, as a consequence of lots of people use Blender, etc, or play AAA games.
How many build a "Fastest HTTPS AES Decryption rig"? I'm not saying they don't exist, just that they're small minority, most likely.
Back to square one, if GBench shows web performance, and most people wants to know other kind of performance, how come GB is still the first one to pop up in leaks??
It's a mismatch, to say the least. That's without touching the aspect of benchmark quality. There are more suitable benchmarks, but they never show up in leaks. Exactly. It doesn't define the next build, far from it. (Admittedly, no individual benchmark does, but you get my point.) Yup. Just look at Ryzen 5000 Hacintosh machines, way ahead of W10 counterparts. It's supposed to be OS agnostic tho.. :D
The integer workloads are 65% of Geekbench.
Which consists of compression, HTML5, PDF rendering, and other such common tasks.
CLang is probably not so common, but probably is representative of Javascript. SQLite is in a bunch of random stuff, so its probably a good benchmark today.
---------
Raytracing, Machine Learning, etc. etc. are Vectorized-based tasks, taking 35% of the weight. The vectorized / floating point tasks are clearly aimed at the scientific community, I guess the "hardcore" benchmarks you're interested in. But I would argue that those tasks are quite uncommon for a typical computer user today.
Look at your URL bar, every place it says https and not http (with attendant insecure site browser warnings), you are using AES. Encrypted files, filesystems, and so on use AES. 5% weight seems like a reasonable number for a client system.
Ivy Bridge and Haswell made huge improvements on AES. Haswell was about 4X faster at AES vs Sandy Bridge and about 60% faster than Ivy. The difference in that case is palpable while using a browser on modern AES encrypted websites, especially with multiple encrypted tabs/connections. I will admit there is not as much of a user feel difference after that, beyond a point a user doesn't feel the difference, but AES is most definitely a thing that affects the user experience - and you can feel it if you swap between SB and Haswell boxes.
AMD Zen 1 started the trend, pushing 2-AES pipelines per clock tick, doubling its AES-performance over Intel. Intel pushed back with their own 2x AES pipeline design, then AMD Zen3 allowed a 2nd doubling, allowing their 256-bit vectors to perform 2xAES per pipeline per clocktick (or now 4x 128-bit AES calculations per clocktick). Intel is pushing back by making AVX512, or 4x AES on 512-bit registers to be pushed.
If anything, these CPU-manufacturers prove how important AES is to today's workloads, be it server or client. Apple has extremely fast AES units, AMD has extremely fast AES units, Intel has extremely fast AES units. Everyone's optimizing AES here. This isn't an Intel or Geekbench thing: literally the entire industry is pushing faster-and-faster AES performance.
Youtube? Delivered by HTTPS. Netflix? Each 30-minute to 60-minute episode at 1080p is 4GB to 10GB. All of which has to be AES decrypted as you're watching. Everything you're doing on the internet is HTTPS encrypted and goes through that AES core before any further processing (decoding, or rendering) can be done. Its a non-trivial bottleneck in all web-based applications.
Seeing 5% weight to it is fine.
