ASRock B550 Taichi Motherboard Review

Manufacturer: ASRock ASRock B550 Taichi Motherboard Review

The B550 Taichi is not only ASRock’s highest-end B550 option, but it also has the distinction of being the most expensive B550 motherboard available today, with a $299.99 price tag that crosses completely into X570 territory.

In this review we will take a look at this board’s design and features, talk about the pricing overlap issue between X570 and B550, and, on a related note, try to understand why ASRock has positioned this model to compete directly with their own X570 Taichi at the same price point.

Manufacturer Description

“Taichi represents the philosophical state of undifferentiated absolute and infinite potential. A motherboard that fulfills every task – with style! Become like water. Shapeless, formless, versatile for any situation.”

The B550 Pricing Overlap

At first glance AMD’s B550 chipset (first announced back in May) might appear to be the logical successor to B450, destined to become the basis of many budget Ryzen builds. But things are a little more complicated than that. AMD’s B550 chipset is positioned as a lower-cost alternative to X570 for Ryzen 3000 CPUs. And to be sure, there are significantly more X570 motherboards over the $200 mark than below it. But B550 has not exactly been a universally low-cost option, either.

B550 also loses backwards compatibility with pre-Zen 2 cores found on X570 chipset boards. In other words, B550 boards only support the current Ryzen 3000 series processors and future APUs – with the current products like the Ryzen 5 3400G disqualified due to its older Zen+ CPU cores. But if you are shopping for a motherboard to support one of the current Ryzen 3000 CPUs and don’t need the additional expansion capabilities provided by X570 chipset, then B550 is often a good way to make your budget go farther.

However, just to complicate things even further, there is a considerable amount of pricing overlap between the B550 and X570 boards, with a number of options from multiple vendors currently competing with one another at the same price point. And there is no better example of this overlap than the motherboard we’re taking a look at today: the ASRock B550 Taichi!

Taichi vs. Taichi (compare these two Taichi motherboards using ASRock’s website comparison tool, linked here)

If you’re familiar with the Taichi branding, you know that means a high-end option in the ASRock product stack. And for both the B550 and X570 option – with the same premium Taichi branding – to be available at the same price (right now, anyway), it seems like the X570 would be the obvious pick. But it actually isn’t that simple! Things have changed in the year since the original X570 launch, and the B550 version does boast some advantages.

There are meaningful differences that actually favor the B550 over the X570, beginning with power delivery. The B550 Taichi offers 16 phase power with dual 8-pin connectors, while the X570 Taichi is a 14 phase design with standard 8 + 4-pin power. Networking has also improved with the B550 Taichi, moving up from Intel I211AT 1GbE with the X570 to 2.5GbE capable Intel I225V. Wireless is unchanged, with both boards sporting an Intel 802.11ax solution.

And the last notable difference is in rear I/O, with dual display outputs – HDMI and DisplayPort – on the B550, and only a single HDMI output on the X570. This is a clear indication that the B550 Taichi is meant as the high-end option for AMD processors with integrated graphics. (Those have to be coming soon to the DIY market, right?)

B550 Taichi Board Design

ASRock offers a different look for the B550 compared to the X570 Taichi, with the same gear-infused brushed metal brown/gold design elements as the recently-reviewed Intel Z490 Taichi. I really like this look, with its coppertone kind of feel (if anyone remembers that era of appliances).

VRM heatsinks are substantial, which makes sense given the impressive 16 phase power design with dual 8-pin 12V connectors. The B550 Taichi also features fast Intel networking with 2.5 Gigabit LAN and Wi-Fi 6 onboard, plenty of rear IO connectivity, and even a Type-C USB 3.2 Gen2 front panel header.

We aren’t going to go in-depth on the components found on the PCB, with resources in that department available from places like this already, but here are some highlights:

The B550 Taichi finishes off its premium appearance with a brushed aluminum backplate that covers about half of the PCB, with a cutout around the socket area to avoid impeding CPU cooler bracket swaps.

B550 Taichi Performance

Motherboard performance testing can be a daunting task. It starts to feel like an extension of quality assurance when test after test is run to attempt to isolate often minute performance deltas between motherboards featuring identical chipsets. It’s not like the old days, when a given platform had competing chipsets and board designs were considerably less standardized.

Nonetheless, we did run the ASRock B550 Taichi though its paces, to some degree. Some consumer benchmarks were performed, with the usual representation of Cinebench, Geekbench, 3DMark, and a couple of others. In comparing these results to our most recent benchmarks with the same Ryzen 9 3900X processor on an X570 test platform, the results were, as expected, very close to one another in most instances.

ASRock B550 Taichi Motherboard Review - Motherboards  15

To begin testing, I decided to try out the board’s XMP compatibility using a G.Skill Flare-X kit certified at 3200 MHz with aggressive 14-14-14-34 timings at 1.35V. Using the auto XMP-equivalent setting in the UEFI setup, subtimings were incorrect, with the automatic tRC setting of 73 quite a bit higher than the XMP profile’s value of 48.

After manually configuring the memory to 3200 MHz and 1.35V, and setting the timings to 14-14-14-34-48, the system was completely stable through all testing. Manual intervention is sometimes necessary on AMD boards with high-performance memory, anyhow, and I didn’t run into any GDM (Gear Down Mode) latency weirdness with this motherboard/RAM combo – though memory speeds with the kit are rather modest by today’s standards at 3200 MT/s.

GPU Drivers NVIDIA GeForce Game Ready 445.87

I had mentioned above that CPU performance with our Ryzen 9 3900X was very close to our most recent reference benchmarks using an X570 platform (obtained using an MSI X570-ACE with AGESA 1.0.0.5), and if we were to go though every result you would see some slightly mixed results, depending on the benchmark. There are potential performance differences between AGESA versions, of course, and in this case we are comparing X570 AGESA 1.0.0.5 to the B550’s AGESA v2 1.0.0.2.

In single-threaded testing the Ryzen 9 3900X scored an average score of 519 over three runs, with multi-threaded scores averaging 7039. Performance was higher with the X570 ACE in this test, with an average single-thread score of 529 and multi-thread average score of 7106. In 3DMark the overall/GPU/CPU scoring breakdown was 11191/11066/11963, and with the same CPU/GPU combo on the X570 platform we saw scores of 10974/10866/11634.

Geekbench 5.1 average overall scores with the B550 Taichi were 1335 single, 11215 multi. This B550 test system should have an advantage with low-latency CL14 memory vs. the 16-18-18-36 kit used in the X570 ACE results in an overall test like Geekbench, with the latter providing average scores of 1341 single, 11191 multi. Higher single-core, and lower multi-core results, but not by much in either direction (again, tests run using different AGESA versions).

We could go through more tests, and more back and forth results, but in the end these platforms offered CPU performance within about 1% of each other. Features and price will naturally be more important considerations when comparing X570 vs. B550. However, I was interested in the internal/external storage performance with this B500 Taichi board, and to this end we ran speed tests using the fastest options we had on hand.

A 1TB CORSAIR Force Series MP600 Gen4 PCIe NVMe SSD averaged 4101.4 MB/s across a long (40 minute) linear read test, with our fastest external NVMe solution (the recently-reviewed combo of a Samsung SM961 NVMe SSD in an Orico enclosure) resulting in maximum transfer speed of 905.6 MB/s using the motherboard’s rear USB 3.2 Gen2 Type-C port.

Final Thoughts

The ASRock B550 Taichi is a high-end option for AMD’s B550 chipset, and is impressively specified and nicely built – as we have come to expect from ASRock’s Taichi boards. At $299.99 any B550 board is a tough sell considering its position relative to X570 options – including ASRock’s own X570 Taichi at the same price. But if you are content with onboard audio and networking, and thus have limited expansion needs beyond a single GPU, X570 is probably overkill, anyhow.

Checking prices on Newegg as of this writing (8/17/20), there were 26 AMD X570 boards priced above $200, and 17 X570 boards below $200. Moving to AMD B550 boards, there were just 8 above $200 (with the ASRock Taichi the highest at $299.99), and 33 priced below $200. In other words, B550 is clearly the less costly platform overall, though a significant overlap exists. Having now used the word “overlap” for about the 60th time, I’ll move on.

If you are considering an ASRock board for your Ryzen build, and the premium Taichi option is $299 for both B550 and X570, the X570 might seem like an obvious pick, though enhanced power delivery and networking (no to mention passive chipset cooling) from the B550 Taichi might be enough reason to downgrade chipsets. It’s a tough call.

On its own merit, however, the ASRock B550 Taichi is a solid option with premium features that give most X570 motherboards a run for their money.

    There is something I have noticed with 550/570 boards. While the chipset offers support to configure two X16 PCIe slots as x8/x8, most manufacturers only connect the first PCIe X16 to the CPU. ALL other PCIe ports, even if they pose as X16 ports, are connected to the chipset with it’s extremely limited number of PCIe lanes. This means less bandwidth of course and stuff getting disabled if you connect something here are something else there.

    Taichi is one of the few boards that split those 16 lanes to two x16 PCIe ports. The other boards look more like microATX boards in an ATX form.

      This one still looks like a mATX board in ATX shape, even with the PCIe bifurcation. mATX has room for 4 PCIe slots, there are plenty of slots to choose from for PCIe bifurcation. B550 simply cannot meaningfully take advantage of the ATX form factor, even when splitting the CPU PCIe lanes. The reason such boards exist and sell is because people for some reason prefer to buy ATX form factor (they probably believe the larger size of an ATX board equals better/more features)

    at 300 bucks why would anyone even consider any B550 when the MSI Tomahawk , the Gigabyte Arourus Elite , and many other X570 offer more PCIE 4.0 lanes and faster innerconnect between the cpu and the chipset

    So taking a handful of pictures, copying some specs on the box and including a Cinebench score is a motherboard review. Pathetic content.

      Cinebench and 3DMark!

      Just kidding. In addition to Cinebench R20 single and multi-threaded results with the R9 3900X on both the B550 and the X570 motherboards I also included single and multi-core Geekbench 5.1 scores for both systems, and provided a look at storage throughput results with the B550 board.

      If you had done more than scroll past the images, you’d have noticed those numbers 😉

        Modern motherboard reviews focus on VRMs, if the advertised specs of phases and stuff are true or not. Because it seems that motherboard makers lie in that area. Also VRM temps.
        You might consider adding those in future reviews.
        Things are getting way more technical in motherboards now that CPUs tent to ask much more power than their TDP, even at stock.

          Modern motherboard reviews are high-level YouTube videos. And it’s not in-depth to just list the parts on the board if I’m not going to be stressing it to essentially do product validation – not the intent of this review (and I say that in the intro to the performance section).
          And how, may I ask, am I to properly stress this 16-phase power delivery with a 7nm AMD Ryzen desktop CPU, exactly? I think it’s safe to say ASRock “overbuilt” this a bit for a B550 board.

    Just a little addendum here for the comments section: The primary focus of this review (including 466 words in a section called “the B550 pricing overlap“) was to talk about the overlap in pricing between B550 and X570, with this the best possible example of that as ASRock priced the B550 Taichi at the exact $299.99 retail as their existing X570 Taichi.

    Since B550 is positioned as a more affordable platform vs. X570, it’s very interesting to see some of these boards instead showcase some of the improvements (enhanced networking, etc) that are becoming more mainstream in the year+ since the X570 launch.

    Thanks Sebastian another excellent review, its a pricy board but you are getting high quality. The $299 US retail price probably indicates a price around $400 + here in Australia.
