"a uvek su prvi ddr5 slabiji od top ddr4 , tako uvek bilo."

U ovom slucaju ne. DDR4 je poceo sa 2400 (ili bese 2133) i to nije bilo brze od TOP DDR3, ali ovo pocinje sa 4800.
2133 cini mi se.
Ma da to je kao brzi 20% RAM ili nesto 800mhz, a onda kada se testira u realnom radu ispadne 2 fpsa vise za ulaganje od 500e vise.
Nema zaletanja dok ne vidim testove u realnom radu, ne nasedam odavno na reklame.

Evo i prvih testova, nad procesorima koji su prodati pre 30.3
Improvements for Desktop, Sort Of

Rocket Lake brings to the table a big core design with new features such as AVX-512 and PCIe 4.0. The core is so big that in order to keep die size, yield, and costs similar to the previous generation, the final design only has eight cores rather than ten. This would appear to be a 20% regression in absolute performance, however Intel is promoting a +19% average performance gain, evening it all out, while also providing the new features listed above. That +19% also should apply to single thread situations, enabling faster single user response time.


To validate Intel’s claims here, we run our industry standard benchmarks, such as SPEC, and compare the i7-10700K to the i7-11700K. Though this testing, we can confirm that Intel is correct on that +19% claim, however that isn’t an overall performance uplift and there’s a big asterisk next to that number.


All workloads at their core, even when browsing the web or word processing, can be split into integer (whole numbers, most workloads) and floating point (numbers with decimal places, workloads with math). In our testing, we saw the following:


  • Single thread floating point: +19.0%
  • Multi-thread floating point: +19.5%

Sounds great, right?


  • Single thread integer: +13.0%
  • Multi-thread integer: +7.3%

Oh. While Intel’s claim of +19% is technically correct, it only seems to apply to math-heavy workloads. The benefits of non math-based throughput are still better than average, 7-13%, but vary rarely do Intel’s big claims come with an easily identifiable asterisk.


When we look at our real-world data, in almost every benchmark the 11700K either matches or beats the 10700K, and showcases the IPC gain in tests like Dolphin, Blender, POV-Ray, Agisoft, Handbrake, web tests, and obviously SPECfp. It scores a big win in our 3DPM AVX test, because it has AVX-512 and none of the other CPUs do.

A Comment on Gaming: Core Latency

Users looking at our gaming results will undoubtedly be disappointed. The improvements Intel has made to its processor seem to do very little in our gaming tests, and in a lot of cases, we see performance regressions rather than improvements. If Intel is promoting +19% IPC, then why is gaming so adversely affected?


The answer from our side of the fence is that Rocket Lake has some regressions in core-to-core performance and its memory latency profile.
