The EVGA Z590 Dark Motherboard Review: For Extreme Enthusiasts
by Gavin Bonshor on October 15, 2021 9:00 AM ESTSystem Performance
Not all motherboards are created equal. On the face of it, they should all perform the same and differ only in the functionality they provide - however, this is not the case. The obvious pointers are power consumption, POST time and latency. This can come down to the manufacturing process and prowess, so these are tested.
For Z590 we are running using Windows 10 64-bit with the 20H2 update.
Power Consumption
Power consumption was tested on the system while in a single MSI GTX 1080 Gaming configuration with a wall meter connected to the power supply. Our power supply has ~75% efficiency > 50W, and 90%+ efficiency at 250W, suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency. These are the real-world values that consumers may expect from a typical system (minus the monitor) using this motherboard.
While this method for power measurement may not be ideal, and you feel these numbers are not representative due to the high wattage power supply being used (we use the same PSU to remain consistent over a series of reviews, and the fact that some boards on our testbed get tested with three or four high powered GPUs), the important point to take away is the relationship between the numbers. These boards are all under the same conditions, and thus the differences between them should be easy to spot.
In our power testing, the EVGA Z590 Dark performed well, although it wasn't as power-efficient as other Z590 models we've had on test.
Non-UEFI POST Time
Different motherboards have different POST sequences before an operating system is initialized. A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized). As part of our testing, we look at the POST Boot Time using a stopwatch. This is the time from pressing the ON button on the computer to when Windows starts loading. (We discount Windows loading as it is highly variable given Windows-specific features.)
EVGA put on a solid display in our non-UEFI POST time testing, with some of the quickest boot times into Windows we've seen. We did manage to shave around half a second of time when disabling the networking and audio controllers, however.
DPC Latency
Deferred Procedure Call latency is a way in which Windows handles interrupt servicing. In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority. Critical interrupts will be handled as soon as possible, whereas lesser priority requests such as audio will be further down the line. If the audio device requires data, it will have to wait until the request is processed before the buffer is filled.
If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time. This can lead to an empty audio buffer and characteristic audible pauses, pops, and clicks. The DPC latency checker measures how much time is taken processing DPCs from driver invocation. The lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds.
Perhaps the most surprising result in all of our testing came in DPC latency, which we test at default settings out of the box. The EVGA Z590 Dark gave us our lowest latency of all the Z590 motherboards we've tested, with a latency of 47.4 microseconds which is incredible.

Value is all relative to what a user is willing to spend. For extreme overclocking, that's dependant on the qualityAlistair - Friday, October 15, 2021 - link
Quick! Buy it 2 weeks before it is obsolete! Hurry! ;)Silver5urfer - Friday, October 15, 2021 - link
Obsolete ? LGA1700 ADL is going to be a generation first product on DDR5 with Gear 4 and Gear 2, on top of new trash cores shoved in because of high power consumption. Plus a basic PCIe5.0 for GPU X16 only. Yeah more DMI and more lanes but questionable Intel Hardware Scheduler on top of the big little BS first adoption on top. Plus the added cost for all the new tech.If we follow the leaks ADL barely matches Zen 3 in SMT and perhaps in ST boost how it translates to real world ? Gotta see, RKL was also like that but came at huge power spike and not much in SMT. This new ADL has inferior cores going to magically beat in real workloads ? Nah.
Nope this platform is not Obsolete only issue is PCIe NVMe SSD slots aren't there and must use PCIe slot and RAID them. If used with 10th gen then PCIe3.0 will be a negative on the GPU lane when used with NVMe SSDs.

You can buy it using DDR4 and it is in no way inferior, if you don't want DDR5. The new big cores are just better than Rocket Lake big cores, so who cares about the small cores, those are just extra. With Intel you can even disable any cores you don't want. Why are you comparing to AMD when we are talking about Z590 being obsolete vs the latest Intel, AMD has nothing to do with my comment. A lot of funny responses in your comment.Silver5urfer - Friday, October 15, 2021 - link
It's not obsolete is the fact gauging by the performance it offers. The fact that AMD was mentioned is because on how RKL was compared to it and had ST advantage but nothing in SMT and huge power draw.Small cores no one cares ? Are you drunk lol. Intel is screaming from their chest that these 8x Atom trash are better than SMT cores AND the fact on how the Cinebench leaks showed it barely reaches to AMD's top SKU in the same tests. And you think disabling those small cores is going to net you the performance boost that Intel is claiming, what a pathetic joke. Those cores are needed if you disable you lose SMT Multicore advantage. Period. AND finally DDR4 is Gear 2 by default there was a latest leak saying Gear 1 is maxed out at 3600MHz probably similar or could be worse than RKL IMC.
You took the AMD and other aspects and discarded everything related to being a new platform on top of the extra costs, done with your kind of garbo useless replies.

Assuming anyone will be able to actually find them in stock. I wasn’t under the impression intel had solved the silicon shortages.Wrs - Sunday, October 17, 2021 - link
Oh come on, Z590 is at higher risk of obsolescence than a typical chipset. Every CPU supported is 14nm. You could be stuck between the power hungry RKL and the soon to be two generation lag of Comet Lake. Both already have problems comparing to Ryzen.LGA1700 should offer you the ability to reuse ddr4. The number of technologies being added is what obsolescence is about, no? The only thing to save Z590 from obsolescence is if ADL is trash, and you simply don't know that, not from the public leaks.

That makes no sense. RKL is the fastest gaming CPU where it counts, minimum frames per second / 99th percentile. https://www.tomshardware.com/reviews/best-cpus,398... Take a look for yourself. Who cares if it's 14nm? Larger process nodes have their advantages as well. Performance is what matters. If you're looking to save on energy, buy yourself a tablet. The only thing obsolete is whatever you're running in your rig today instead. Ryzen has plenty of problems, you're just not informed. Stay salty, poor boy.Wrs - Sunday, October 17, 2021 - link
Obsolescence is about what's around the corner, not what you have today. I just think buying any Z590 today is asking for buyer's remorse. Around the corner, we're expecting expanded cache Ryzens for AM4 - which may not be much except for gaming - and ADL on Z690. ADL consists of two new cores on a finer process (I consider it coequal with Zen 3's 7nm), translating to a higher overall core/thread count and cache, and ITD with all its potential game optimizations. Unless ADL has a poor showing or developers don't support ITD, won't ADL make Z590 suddenly feel lackluster? It could be a mild Pentium 4 moment.It's true that RKL holds pole position for most games right now. It's just that the edge over a 5800x is really small, the cost of that power budget is substantial, and many of us weigh other workloads too, including multitasking while gaming.

As a platform probably yes because of only I/O - PCIe3.0 for CML and RKL gettin Gen 4 but at 8C max and insane ABT power spiking and heat. In terms of performance not yet. ADL is a brand new platform and with questionable core design it's already having a lot of news around DRM, Application optimizations and etc. Why should I pay for beta testing a product ? Esp when the DDR5 is so new and PCIe5.0 barely has any effect and the whole socket longevity along with Intel Thread Director drama and Win11 shenanigans ??Intel clearly lost their way. RKL was the first sign of that, IMC massively downgraded on that. With ADL DDR4 is not going to run at 4000MHz C15. It's not going to happen. The leaks show max of 3600MHz just like AMD, AM4 platform has a TON of issues, I was on the verge on pulling a trigger on Crosshair 8 Dark Hero but the USB drop out, WHEA issues, random PCIe issues, million AGESA updates. FCLK instability all these are there some of them only if you push the CPU but what's the point in buying a 16C or 12C processor and shoving it in an OC capable high VRM mobos likes of Aorus Master or Xtreme etc or even the X570 DARK and run it on all stock ?
All of these compound to one thing per my analysis, CML / RKL LGA1200 is a better mature platform to put money in for the next 5 years of it's life.
