Intel Core i9-11900T "Rocket Lake" Processor Allegedly Catches Up with Zen 3 in Single-Threaded Performance
When AMD announced its Ryzen 5000 series of processors based on the new Zen 3 architecture, the performance of these processors was the best on the market. Even in our own testing, we have found that AMD's Zen 3 core is the highest performing core on the market, even beating Intel's latest and greatest, the 10th generation of Core processors. However, Intel has been doing some silent work and the company has developed a new core to be used in the 11th generation "Rocket Lake" platform. Codenamed Cypress Cove, the design is representing a backport of the 10 nm Sunny Cove design, supposed to bring around 19% IPC improvement across the board.
If you were wondering if that was enough to catch up with AMD's Zen 3 IPC performance, look no further because we have Geekbench 5 performance results of Intel's 35 Watt Core i9-11900T processor. Having a base frequency of only 1.51 GHz, the CPU is capable of boosting one or two cores to the very high speed of 4.9 GHz, giving us a good example of the single-threaded performance we can expect from this CPU. In GB5 tests, the Core i9-11900T has managed to score 1717 points in the single-threaded test and 8349 points in multi-threaded results. Comparing that to something like AMD Ryzen 5800X, which scores 1674 points in single-threaded results, Rocket Lake's Cypress Cove core has managed to be 2.5% faster than Zen 3. However, in multi-threaded results, the AMD chip is unmatched as the low TDP of the Intel processor is stopping it from reaching full performance.

And geekbench? come on honestly! .......
Either way, single-core performance is within a percent or two at the same frequency. Competition is only good from our consumer perspective.
4.9GHz vs 4.7GHz max single core boost = 4% difference in clock speeds (being in Intels favour)
1717 vs 1674 is the max single thread score of both CPU's mentioned (being in Intels favour again)... but when we take 1717 (the score of the mentioned 11900T) and reduce it by 4% to take into account clock disparity between CPU's, we actually get a score of 1648 for the Intel part... less than the 5800X's score, at the same clock speed.
Or, in "points-per-ghz":
1717/4.9=350.40
1674/4.7=356.17
Maybe I'm mistaken, but that doesnt equate to a 2.5% lead.
Edit to ask @W1zzard for employment due to my amazing mathematical skills. Any chance? :roll:

Plus AMD forums are full of complains
Consumers are returning damaged or alleged faulty CPU's, but the issue isn't the Processor, it's the Motherboard Manufacturers stuffing up voltage regulation.
Anyway, enough off topic from me.

Not sure what your comment has to do with 11900T and 5800X comparison though.
You probably know that Intel is still on the 5-6-year old 14nm process, and its processors are slower, have less multi-threading, are more power hungry and are not reliable because of security vulnerabilities.
So, given all these inferiorities, it is a tough task to remain positive towards Intel.
Hell, even Intel's CEO lost his position recently, what more can or shall we add?
This leak seems top indicate Rocket Lake is only slightly slower compared to Zen3 which is made up by slightly higher frequency.
Less multi-threading and power-hungry are still accurate enough.
Rocket Lake being Ice Lake/Sunny Cove derivative, it should have most of the security vulnerabilities fixed.
