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.

    weird to see in a couple cases the 3700X beating the 3800XT when they're the same part binned differently. Reply

    I was about to ask the same thing, especially since the article doesn't go out of its way to explain the anomaly, unless it's that "new bench suite". But then the charts would not be indicative of anything. Reply

    It's within 3%, which could just be run-to-run variation. Reply

    I guess I was expecting 300MHz to make more of a difference. At least enough to keep the 3800XT consistently above the 3700X even if in the margin of error. Are those benchmarks so insensitive to frequency? I can wait for the full reviews, or the new benchmarking suite. Reply

    The heat, the heat, the heat... 3700x runs a Little bit cooler and can maintain higher clock a Little bit longer. Reply

    While this is a technically accurate explanation it shouldn't be the case on such a review. I mean a benchmarked CPU shouldn't be limited by its cooling. The point is to show what the CPU is capable of (at least with reasonable cooling options) not highlight the inadequacy of the cooling used. I hope that at least AMD's recommendation of an "AIO solution with a minimum 280mm radiator" was followed. I'm trying not to speculate since I have nothing to base this on.

    For a benchmark I'd definitely oversize the cooling. People looking at higher end CPUs and who care about top performance will probably do the same.

    Then do more runs? Otherwise the test has no value. Reply

    Isn't this a classic case of not showing the proper comparisons? I get that AT got to test the 3800XT in this round, but it's unfortunate we can't compare against a 3800X.

    I just feel like sometimes the choice of comparisons here doesn't make any sense. You need to look at what consumers will actively compare against. For instance does a user today buy a 3800X at a reduced price or wait for their retailer to have a 3800XT in stock? Those are questions a reader might want to have answered.

    They are just getting started and I assume the comparisons you want will be coming. However they will show that the XT CPU's are essentially pointless. Obviously retailers can't sell an X and an XT for the same price, so they wont be the same price. Example: At Microcenter the 3900XT is $499.99 while the 3900X is $399.99. But who is going to pay $100 more for the XT when the only difference is 100 Mhz on the maximum boost? They don't have a 3800XT yet but 3600 XT Vs 3600X is $249.99 to $199.99. Who will pay even $50 extra for the added 100 Mhz?

    So I expect the benchmarks of any XT to be close enough of a tie with the corresponding X as to make no difference. Even before this, many including me were passing on the 3800X in favor of the 3700X because the extra Mhz mostly didn't matter. The only way the XT's make sense is if the older X CPU's disappear from the market.

    "The only way the XT's make sense is if the older X CPU's disappear from the market." - exactly! Reply
