If they will be competetive (I'm not into leaks and gossip stuff, but from what I know they will be comparable), it's worth to wait a little longer for non-K ones: for last few years they were noticeably less power hungry (but you can power limit any ofc and it somethimes even make sense with flagship ones) noticeably cheaper and unnoticeably slower (at worse literally few %). There are plenty of materials explaining CCDs, but instead of worrying about that I would wait for Raptor Lakes - then we will see what is better choice for you. I just hope I can still air cool the 7700x. If I got the 7700x (the sweet spot for me since I can't justify the extra jump in price for the 7900x) the eco mode feature would be useful for everyday productivity, whereas when I want to do something more intensive like video editing or 3-D modelling, I suppose I could always turn eco mode off to get full power. However, I also found out that in Zen 4 you can turn on an eco mode feature (requires rebooting) which drastically reduces temps, yet does not impact performance too much. So it looks like the 7700x will carry on the same design as the 5800x (with only one CCD) and run hotter than the other 7900x and 7950x. ![]() When there is only one CCD, temps are higher, as in the case of the 5800x and 7700x (one CCD with 8 cores). When the heat load is spread out over two CCDs, apparently temps don't get quite as hot. I'm really confused about whether to get a Zen 3 or 4 system.Īfter doing some research, I found out that in Zen 3 there were two CCDs on the higher end 5900x and 5950x CPUs, and now also in Zen 4 with the 7900x and the 7950x. My needs are modest right now (90% office work, 10% video editing, 1% 3-D modelling), but that could change in say 5 or 6 years. I don't game at all, but I want to get more into video editing. I'm not sure if 6 cores would be enough in the future. I'm also wanting my next build to last a long time, so future proofing is also on my mind. For my use, I probably don't need more than 8 cores. Second: I am trying to decide between a 5900x, a 7600x and a 7700x. My first question is: For the 8-core Zen 4 (7700x) will this follow the same CCD issue as the previous Zen 3, 8-core chip and run even hotter than the other 7000 series? Now with Zen 4, all the 7000 series CPUs reportedly run hot. So, at the time, when I was contemplating getting a Zen 3 system, I was looking at a 5900x rather than the 5800x to avoid the hotter CPU. This was apparently because of the CCD, for technical reasons I don't quite understand. In Zen 3, the 8-core 5800x ran hotter than the other Ryzen 7's and even Ryzen 9's. A recent AMD demo showed a Zen 4 CPU running at little more than 5GHz on all cores while playing Halo Infinite.I have a couple of questions about thermals and performance comparing Zen 3 and 4. Clock speeds look to be increasing significantly as well, with boost frequencies projected to exceed 5GHz. Raphael (zZEN4) will be built on TSMC's new N5 process (5nm). These new processors will be the first to run on AMD's brand new LGA AM5 socket, which includes PCIe Gen 5 capability. Looks like Raphael got it's production model ID (the previous one was 96), probably stepping RPL-B1.ĪuthenticAMD Family 25 Model 97 Stepping 1 / A60F11ĪMD's Zen 4 architecture is expected to debut in the second half of 2022 as the Ryzen 7000. This Zen 4 chip would be an 8-core pre-production prototype with SMT enabled if this is correct. The core count is labeled as processing units by therefore we assume it covers the thread count of the whole CPU. However, for the L2, this is a significant improvement over AMD's existing Zen 3 processors, such as the Ryzen 9 5950X, which has just 512KB. Obviously, this is the L2 cache, as the latest Zen 2 and Zen 3 chips all have 元 cache capacities more than 1MB. Notably the cache, is specced at 1024KB capacity. This specific chip, returns as a Stepping 1 revision, indicating that it is one of AMD's earliest production versions employing the Zen 4 architecture that we have seen, implying that it is a pre-production model that is not yet ready for the general market. Furthermore, other parameters, like as the number of cores and cache sizes, imply that Zen 4 is nearing completion. This additional data includes the CPU family, model, and stepping name. AMD's first pre-production version of its future Zen 4 CPUs appears in a spec sheet.
