Final Words & Conclusion
Conclusion
Not bad, the Vision G was designed to be the more value alternative in the Z490 range from Gigabyte, which does come at the cost of a down tune VRM design and 50A power stages. Not a big deal really, but if you are an extreme overclocker, there are boards out there with 90A stages that will suit your needs better. Other than that you'll miss out on AX WIFI6 and some more premium audio features. Oh that and lower DDR4 support up-to 4400 MHz, all trivial at best. The asking price is 199 USD and that is the first Z490 motherboard in my hands that seems more affordable, albeit still a lot of money. You do need to like that white design as well of course.
Whenever we write a motherboard review, for the conclusion we need to make a distinction between the CPU and motherboard in the conclusion of course. Everybody will have an opinion about Comet Lake, but for motherboards, you need to be more factual about platform performance and features. Coming from Z390, Z490 really isn't that different in terms of the infrastructure in combo with Comet lake generation processors. The big miss for this hybrid symbiosis of CPU and motherboard is the lack of PCI Express 4.0 support running through the veins of the hardware eco system., and that's a bit of a miss on the intel side. The inserting thing is that Z490 range of motherboards factually is PCIe Gen 4.0 compatible, just not with this processor, here you will need the next-gen Rocket Lake-S series processors. So the 11th generation Core processors will double up on PCI bandwidth, opening up a plethora of options in terms of M2 storage and graphics cards. The reality is also this, do you really need PCIe Gen 4.0 in 2020? We honestly doubt it. A good PCIe Gen 3 M2 SSD is super fast, and for graphics cards, the Gen 3 or Gen 4 link just doesn't matter. In the past with Crossfire and SLI PCIe Generations made a difference, but even today if you go SLI, all data is now passed over the graphics cars though a high-bandwidth interface, internally bridged on the graphics cards. So yes, it matters less. So what's the big difference between Z390 and Z490 then? Well, nothing much on the chipset side really. Yes, the motherboards get a bump to AX WIFI (not this particular model though) and more refined Ethernet jacks starting at 2.5 Gbps. Also, overall the VRM design has been beefed up a notch, but that's a necessity for Comet Lake-S high-end processors really and their high PL2 states. However, making a move from Coffee lake (Gen9) towards Comet lake (Gen10) is not going to move mountains in terms of features and performance.
Power consumption
With these ten cores and twenty threads proc you get a 125 Watt TDP processor. With the system at idle with a GeForce RTX 2080 Ti installed / 16 GB memory / SSD and the Z490 motherboard, I hovered at roughly 60~65 Watts in IDLE. That's okay, the load values are okay as well but definitely higher. When we stressed the processor 100% run we reach roughly 200~250 Watts with the flagship 10-core part. That's the entire system. That is on the high side alright. Then again, does anyone actually care about it when you get performance metrics like shown today?
DDR4 Memory
For Comet Lake-S (as wel as 8th, 9th and now 10th Gen Intel procs) and DDR4 we always say, volume matters more than frequency. A 3200 CL16 to 3600 CL18 MHz kit is plenty fast overall for all your needs. Higher frequency memory is more expensive and does offer better bandwidth but the performance increase in real-world usage will be hard to find. Unless you transcode videos over the processor a lot. As always, my advice would be to go with lower clocked DDR4 memory with decent timings, but get more of it. Don't go for 8 GB, get two or four DIMMs, and in total a minimum of 16 GB. we think the current sweet spot is 3200 MHz (CL14/CL16) or 3600 MHz CL16/CL18).
Performance & tweaking
Once tweaked we noticed that the 10 cores like a bit of extra voltage, we expect all-core tweaks in the 5.1~5.2 GHz marker to need 1.35~1.45 Volts on the processor. While that does increase power consumption, it wasn't something that scared me away. Some platforms will and procs will also be able to manage a lower voltage. If you plan a tweak at that 5.2 GHz marker then remember my remarks on cooling, you will need LCS, that or a very good heatpipe cooler. Again, we have been using an ES sample so I cannot say anything conclusive on the final retail products (these might run a tiny bit cooler). The infrastructure that Z490 offers is easy to use, you increase the CPU voltage and multiplier and you are good to go. Another plus for the Intel platform is that over the years they have been able to refine their memory controllers, pop in anything XMP 2.0 and you have a 90% chance it'll work straight out of the box with very fast memories. VRM temps ran slightly high, but ~80 Degrees C under heavy stress still falls within acceptable limits.
Final words
At 199 USD I'd say this board is a fair deal if you dig the looks of course. The photos are a bit difficult with all that white and our white backgrounds, but it does like nice really. For that money, you'll forfeit WIFI6, slightly lower memory frequency support, and lacks the more expensive headphone amplifiers, etc. All trivial stuff at best. The good stuff is on there making this a complete enough motherboard for many, the VRM design, however, is of lower but sufficient grade. The 2.5 ethernet jack will bring you at least twice the LAN performance, granted you need a compatible switch in our network infrastructure or else you'll be still stuck at 1 Gbps. I do wish the switch market would be more competitive in bringing more diverse options and lower prices available in that segment, But that's another discussion. We do miss the WIFI6 implementation but understand the added costs, and we like the triple M2 slots and six SATA3 ports. Going from Z390 to Z490 is not going to bring you massive differences platform wise other than a new series processor. We doubt that the upgrade from Coffee lake to Comet lake is worth this kind of money really. Platform wise you'll get some added features like AX Wifi and a more luxurious Ethernet configuration on the form of that 2.5 ethernet jacks. While the platform is PCIe Gen 4.0 ready the reality remains that Z490 will only survive two generation s of processors, so Rocket Lake-S is the next series that will finally bring PCIe Gen 4.0, the good news is that this motherboard is compatible or at least should be. It's not listed on the box or as a spec though. So I do hope that once Rocket lake-S is available, Gigabyte will not just 'update' the premium boards only. if you do not plan to go extreme with overclocks and whatnot, this might be just the right board for you. Definitely worth a recommendation.
