Intel’s continuing to bring the heat, literally and figuratively, and is now leveling its new 10C/20T part squarely at AMD. We have a separate in-depth review coming up on the 10600K, which has interesting implications for the R5 3600 and the realm of gaming, but for launch, we need to start with the flagship 10900K. That’s not the 10900X, mind you, but the 10900K, which is the part socketable for LGA1200 and Z490 motherboards. We’ll be looking at whether Intel’s die sanding worked for leveling-off thermals, benchmarking games, initial overclocking on the ASUS Max XII Extreme, production workloads versus the 3900X, and more.

In this content, we’re going to be breaking-down the AMD B550 vs. X570, B450, X470, X370, and A320 chipset specifications number-by-number. Our goal is to look at this purely from a facts-based angle of what the differences are, and those differences will include both numerical specification differences (number and type of lanes afforded) and forward or backwards compatibility differences. This includes the intent of the 500-series chipsets to support Zen 3 architecture (reminder: that’s not the same as Ryzen 4000 mobile, nor is it the same as Ryzen 3000 desktop), while the existing B450 and X470 boards are left to cap-out at Ryzen 3000 series (Zen 2) parts.
We have some additional discussion of the basics of naming, including CPU naming distinctions, in our video component that accompanies this article. You may get more information on the differences between AMD Zen generations and Ryzen generations in that content.
This is the big one: In this review, we’re benchmarking the AMD R3 3300X $120 CPU, but we’re specifically interested in the real-world impact of the CCX-to-CCX communication latency in the Ryzen 3 3100 versus the Ryzen 3 3300X at the same overclocked frequency of 4.4GHz. It’s massive in some instances, beyond 20%, and eliminates the ability to just overclock the otherwise identical 3100 to meet the 3300X performance for cheaper. As discussed in our Ryzen 3 3100 review that’s already live, the 3300X runs a 4+0 core configuration with everything on one CCD, on one CCX, while the 3100 runs a 2+2 configuration on two CCXs on that CCD. We’re going to look at how much that impacts performance, but also review the 3300X versus basically every other current CPU, and a few older ones.
Today we’re reviewing the AMD R3 3100 and Ryzen 3 3300X, but we have a dedicated content piece for the AMD R3 3300X because we added benchmarks for the two CPUs at the same frequency, exposing the latency difference between them. For this specific article and video, we’re focusing all of our attention on the AMD R3 3100 CPU at $100, potentially a high-volume part for budget PC builds. That includes overclocking, power consumption, gaming benchmarks, frequency analysis, production workloads (Premiere, Photoshop, compile, et al.), and more. Our AMD Ryzen 3 3300X review will post within a couple of hours on this one (on YouTube, at least, if not also on the site), and that’ll feature head-to-head 4.4GHz overclocks on the R3 3100 vs. R3 3300X, where the 3300X’s 4+0 core CCX configuration can be tested for its real-world latency impact versus the 2+2 3100.
Writing this review, it felt like we were writing a review script from the same era as the 7700K, and not just because AMD is positioning itself against the 2017 CPU. Back when we reviewed the 7700K, all the comparisons were to the 6700K, the 4790K, the 2600K – the theme was that it was all intra-brand competition. The same is happening now, where we’re throwing a few Intel names out there as comparisons, but until the 10-series, AMD really is just competing against itself. It’s fascinating in a way, because from a reviewer and editorial standpoint, it really does feel like dejavu – except it’s a different company in 2020. The new AMD Ryzen 3 3100 and 3300X CPUs have a release date set for May 21, 2020, with the Intel 10th “Gen” release date set for May 20, 2020.
It’s time again for our CPU testing methodology to be updated, alongside the test bench. We’ve done some significant streamlining behind the scenes that make these tests easier to run and the results easier and more accurate to process, but on the public side, we’ve completely overhauled the software suite we’re using. Last time we updated our testing methodology, we added a code compile benchmark that was short-lived. The test featured GCC, Cygwin, some other environments, and ended up being a top-to-bottom sort by cache. We ditched that test (and consulted Wendell of Level1 Techs on it in this video), and we’re just now replacing it. New code compile benchmarking (with more usefulness) has been added for 2020, alongside the addition of Handbrake H.264 to H.265 transcoding (ranked by time), updated Adobe Premiere video rendering and Adobe Photoshop benchmarks, updated file compression and decompression benchmarks, and more. Gaming gets a total overhaul, too, with a big suite of new games added.
Additionally, we’ve updated several existing game and production benchmarks from last year’s suite, with a few left unchanged. This is to keep producing data that we can still compare to old data, which is useful for rapid analysis of parts that may not have been re-tested in the current year. For example, if we were testing a 10700K and wanted to reference its performance vs. a 2600K, but didn’t have a fresh retest, we could reference data from GTA V, Tomb Raider, Civilization, and ACO to form an understanding without fully retesting. We try to limit this, but time often gets the better of us, and it’s good to have reference points to ensure ongoing accuracy.
Intel today announced its 10-series desktop CPUs, which it’s calling “10th Gen,” and that includes the 10-core / 20-thread Intel i9-10900K. Intel confirmed several of the specs we’ve exclusively published in the past couple of HW News episodes, but we can now talk about it in a more official capacity. A bigger focus on thermals was one of the key points, but we were also interested to see expanded overclocking support as a heavily promised feature for the 10-series Intel CPUs. Intel’s press announcement left a lot to be desired from an informational standpoint and the company ended the call before getting through all of the press questions, but we still have information we can work through today. Unfortunately, the press call was not without its usual stuffing of marketing that bordered on territory of “probably literally made up,” but Intel later retracted those claims after questioning. More on that later.
In this week's hardware news, we have an exclusive news item pertaining to Intel's 10-core CPU thermal packaging for the Z490 mainstream desktop part. We've verified the news as accurate and are working to verify additional information sent to GamersNexus by industry partners. In the meantime, DDR is in the news again, GDDR5 is almost out of the warehouses as GDDR6 replaces it, and Atari further taints its name.

AMD's been in the news a lot this week, but for various reasons. One of the bigger stories was that of the Threadripper 3990X and its compatibility with various Windows versions, like Windows 10 Pro versus Windows 10 Enterprise. AMD has officially responded to some of those concerns, all discussed in our news recap today. AMD was also in the news for Google's adoption of more Epyc CPUs. Accompanying AMD, Samsung makes the news for advancements in its EUV fabs for 7nm and 6nm products, and Phanteks makes the rounds for its blatant rip-off of the Lian Li O11 Dynamic.

We've received a loaner AMD Threadripper 3990X to work with for an upcoming review, but we also will be streaming with the CPU for multiple overclocking efforts. In the meantime, hardware news is still pushing ahead. News on Intel CPU refreshes, AMD x86 marketshare reports, market analysis on AMD's positioning, and more.

Hardware news is busy this week. We've been in the throes of planning a trip to China for several months now, including a leg to Taiwan to visit several HQs, but may have to postpone due to the recent Wuhan flu outbreaks near some of the regions we were scheduled for. We're also talking about RDNA2, AMD's quarterly earnings and YOY reports, Intel's CacheOut vulnerability, and people who want Windows 7 for free.
