Announced a couple of weeks ago, the new AMD Ryzen 3000XT models with increased clock frequencies should be available today in primary markets. These new processors offer slightly higher performance than their similarly named 3000X counterparts for the same price, with AMD claiming to be taking advantage of a minor update in process node technology in order to achieve slightly better clock frequencies.

The new 3000XT family of processors focuses mostly on boosting the turbo frequency by 100-200 MHz for the same power. AMD states that this is due to using an optimized 7nm manufacturing process. This is likely due to a minor BKM or PDK update that allows TSMC/AMD to tune the process for a better voltage/frequency curve and bin a single CPU slightly higher. 

An update in this range could be indicative of a ~10 mV better voltage for a single core, although this would normally be in the binning noise - for it to be statistically relevant would need a lot of CPUs, so this could just be better binning. However, base frequencies haven’t moved much, so performance-per-watt benefits are going to be somewhat minimal. The biggest uptick would be in 1T scenarios.

Each of the new XT processors is the highest speed variant of its respective class.

Users should note that the prices listed are official SEP (Suggested Etailer Price). In March, AMD did announce a temporary AMD-focused price drop, but that has since passed. Retailer pricing will vary with local sales practices.

The top new processor is the Ryzen 9 3900XT which offers +100 MHz turbo over the 3900X, for the same official price as the 3900X. The 3800XT offers +200 MHz on single core turbo over the 3800X for the same price. The final new processor is the 3600XT, with +100 MHz on the turbo frequency, again for the same price over the 3600X.

In each three cases, the XT processors give slightly better frequency than the X units, so we should expect to see an official permanent price drop on the X processors in order to keep everything in line.

AMD’s announcement today also includes information about thermal solutions. The Ryzen 5 3600XT, with six cores, will come bundled with AMD’s Wraith Spire cooler. For the other two CPUs, AMD’s own press release states that the company ‘is recommending the use of an AIO solution with a minimum 280mm radiator or equivalent air cooling to experience these products at their best’. This does seem somewhat overkill for 105 W processors, especially if the package power tracking on these parts should be ~142 watts, notwithstanding any trickery that the motherboard manufacturers are doing.

These new processors will be supported in any motherboard that already supports Zen 2-based Ryzen 3000 hardware (the cost in BIOS space to add a CPU of the same family is negligible).

Performance

While we have had these three processors in for testing over the last week or so, we are in the process of transitioning to a new benchmark suite for 2020/2021, with updated CPU tests, newer games, and game testing with RTX 2080 Ti graphics cards. This bench suite is still a work in progress with regression testing older models, and so at this point we do not have a strong enough dataset to confidently do the processors a full review in the AnandTech way. A number of the tests use updated software packages, and so comparison to previous versions is not possible, however we do have some metrics which align that we can share with you.

Graphs will be updated as results come in.

As we can see, there isn’t much between the old X models and the new XT models – increasing the turbo frequency a little means that there is scope for increased performance in low thread-count workloads, but ultimately the voltage/frequency curve when we start pushing with more cores loaded counts in those high density benchmarks.

We’re planning on doing a full article with our updated benchmark suite and new tests after we’ve done more regression testing. There will also be a new section in Bench to cover our new benchmark suite. Stay tuned for that.

    I agree with romrunning that he made his point unnecessarily antagonistically, but I agree with it-- MSRP is _really_ not a useful measure for consumers. Reply

    But how is using a price that will likely be outdated and wrong by the time someone reads the article any more useful? Reply

    3900X has been on sale at AMZN for months @ ~$420. Bought min in March.

    How is using a price that is ALREADY outdated and wrong any better? ASP over the previous week or month before publication would be ideal, but the current selling price is good enough.

    MSRP isn't worth the paper it's written on.

    It's worth is as an artificial reference point. It places it more clearly in the line and shows how the manufacturers viewed their product against the competition. Take those numbers as having no units and only relevant relative to the generation. Reply

    I apologize for being "unnecessarily antagonistic". I was just trying to make my point very clearly, not intending to be antagonizing. Reply

    So what price should they use? Even you couldn't pick out a single price for the two parts you mentioned. Reply

    One possibility is to use a graph/ data from camelcamelcamel - they track Amazon price history. In this case, the price history of the 6 or 7 CPUs discussed in this article can all be shown on a single graph and provide quite a lot of information to the reader. Camelcamelcamel only shows a single product’s price history so if Anandtech can show all the CPUs in one graph, that’s added value for Anand readers. Depending on camelcamelcamel’s API, it might be possible to show a live graph so that a reader coming back will see updated price information - this would be useful in the weeks after a new processor comes out, while the street price is still settling.

    That would be ideal, really. Reply
