Ryzen 7 7800X3D on an A620 Motherboard, Can you save HUNDREDS over the X670E?

today we are going to be testing out the a620 chipset from AMD with a ryzen 7 7 800 x 3D now the Curiosity peaked for this motherboard chipset because in the past I have extracted a lot of value out of amd's Cheaper motherboards especially with their high value CPU lineups like the ryzen 5 3600 for example I found that that CPU and that motherboard provide extremely good value for money now what I want to look for with this is if you go with an a620 are you going to be losing much performance versus say an x670 where at computax I was looking for a lot of information not just with gpus and prices and numbers there but also when I started talking to people on the showroom floor they divulged a lot of information to me that I believe I shouldn't know but it regardless I'm going to be sharing with you guys here today a the first of which is the a620 chipset itself it costs 28.50 for motherboard companies to Source this from AMD and that's in bulk as opposed to the x670 chipset that costs the motherboard manufacturers around 54.50 so automatically if you're going for an a620 motherboard you are going to be saving over 25 just like that that's money that you're not handing towards AMD furthermore the requirements for the motherboard manufacturers to make an x670 is that it has to have four slots of memory a much bigger vrm as well as a lot of different features for instance PCA 5.0 compatibility built into the lanes that just adds so much cost on top of the motherboard that by the time you get to the end price an a620 is going to be under half the price of an x670 motherboard which can save you a lot of money especially if you're on the budget but you want to get the best performance possible and today we're going to be doing just that with this chipset and the first of which is the memory overclock capabilities of an a620 motherboard versus an x670 where in this case I was able to lock in with the ryzen 7. 7800 X 3D 6400 megahertz on both platforms meaning that some of the best x670 motherboards at least with this ryzen 7000 generation of chips is going to make no difference to the memory OC capabilities because we're now limited to that ryzen CPU itself the integrative memory controller being captured around 6400 megahertz though what about gaming performance let's test that out right after today's video sponsor and also guys sorry I've been a bit of a Hiatus I will answer that towards the end of the video also never pay full price for Windows 10 or 11 again with today's video sponsor SED Keys you can get activated as little as 15 using that coupon bftyc links in description below foreign [Music] so we've just finished our first round of testing here and we have some really interesting results and this is my first time using an a620 motherboard as well as a 7800 X 3D and what I'm noticing here is straight away there was high idle power consumption on this CPU on this motherboard it was all the time over 30 watts and if we ran it at default memory and default everything it was going up still to around 25 watts or that was the minimum base case however there was one setting I turned off in the Bios that with our tune settings dropped the 32 watts roughly all the way down to 19 watts and this was The Encore SOC always high voltage settings so if you turn this off then it will basically essentially have that scale with the processor and when it's not being when the processor isn't Under full load for example it will drop down the power consumption so if you've been wondering why your 7800 X 3D perhaps runs a bit hotter and perhaps uses a bit more power consumption out of the box then hopefully this will solve that issue regardless of what motherboard you're on the next problem that we were coming into to sort of overcome here was the default power consumption on the a620 motherboard itself and here is where we got 80 Watts out of the box in cinebench R23 at around 17.7 000 points and then if we looked at the motherboard's vrm itself that was going up to around 86 degrees with the heatsink at 61 degrees so for the a620 motherboard this would be the most I would want to use with this combination here would be a 7800 X 3D I wouldn't go any higher unless I could tune the CPU down to around this 80 watt level as going any higher will go over 90 degrees and I generally like the vrm on my motherboard especially if I'm going to be using this combination for a few years to run under 80 degrees so we good news is though we did get that under 80 degrees on the vrm only just and this was when we tuned the CPU with a maximum limit of 75 degrees in the Bios and although ryzen Master opens up on Windows we don't get any control of the x3d chip go back to that temperature limit of 75 degrees on the CPU this is where we actually got the best numbers in terms of average FPS in the 1080p low settings Benchmark with an RTX 4090 on the Last of Us versus the worst case scenario which was just the default CPU with no memory OC at all however one important thing is with this CPU and this motherboard combination rebar resizable bar that will actually be enabled by default so you don't have to worry about turning this on however one setting You may wish to do in the Bios is turn on the maximum utilization of rebar which is what we did going forward with our tuned settings the other good thing is this motherboard capable of 6400 megahertz however I decided on 6200 megahertz because I wanted to drop down the soc voltages as well as the memory voltages too which we ended up with 1.25 volt on our ddr5 memory and on the soc we ended up with 1.18 then now it's time for the second test and that is to whack a water cooler on and let the 7800 X 3D run unconstrained on this motherboard and then we're going to be testing that versus that x670 okay [Music] foreign so now we just finished up with the x670e and the 7800x3d and a water cooler and I decided to compare this versus the results on the a620m hdv m.2 plus and the results were really nothing special the gaming numbers at 1080p lower settings moving on into 1440p high settings and then even 4K Ultra in The Last of Us showed us that we were getting very similar numbers coming down to Mere variance between these two motherboards testing out with this CPU in fact the best results we got in this game was when we were fine-tuning the a620m with the Snowman air cooler though moving on now to D4 now I have to pronounce this game as D4 because I got demonetized in the previous P PC build video that I did with this game and it's the only thing that's really different to what I've been doing at Tech yes City but I wish YouTube would actually give me clarification as to what exactly demonetize the video instead of just outright saying you're demonetized deal with it so it kind of a bit frustrating there but anyway 1080p ultra settings 1440p ultra settings in 4k now we used ultra settings across the board because this game actually has a 400 FPS limit that I didn't know about until testing with the CPU and GPU and so it tended to be low versus 1080p Ultra there's going to be virtually no difference in fps with this combo except the visual quality is going to be significant so here's where we got around 395 average FPS the 0.1 percent lows did drop down to under 100 and I was testing it out in a very heavy dungeon with a lot of creeps so this would be a benchmark that is pretty intense on I guess at times on the CPU and there's a lot going on though at 1440p 310 roughly average FPS and then at 4K 155 this was with the extra HD textures enabled when we installed the game which adds about 40 gigabytes onto the install moving on to Hogwarts Legacy the final title in today's Benchmark here getting over 200 FPS on both configurations at 1080p low settings moving on to 1440p high getting over 150 average FPS and then at 4K getting over 100 average FPS at ultra settings so really when it comes down to gaming you're not going to be losing anything going with an a620 over say the most expensive x670 motherboard now this is where we're going to break it down further in this video and go well if surely if you're spending this kind of money on the CPU GPU you should at least spend a little bit extra on the motherboard and I do agree with that certainly but I do like to test things and know where the limits are especially for entry-level motherboards on the AMD platform I mean for instance would I be pairing a 7950x with this motherboard absolutely not I would go for something a little bit more especially in terms of having some options to tune the CPU which is something I got very little of on the a620 but in terms of it working with these eight core and six core CPUs it works absolutely fine and if you're looking for instance you see a ryzen 7 700 with a cooler on sale because they include The Wraith prism if you see that on sale and then you see this going for under 100 bucks and some cheap ddr5 memory you can put together something really good in terms of your bare bones kit for a new PC build and save quite a bit of money now in terms of the 7800 X 3D I also wanted to test okay was there a big difference between this budget chipset and the more expensive stuff and the answer was especially for gaming a big resounding no now we didn't even bother to update the BIOS which apparently improves CPU performance because I was really happy with the performance to begin with for instance 4K Ultra settings the GPU you when we check closely it's going to 99 which is exactly what you want with your CPU and GPU combo resizable bar is enabled by default and Windows 10 Works flawlessly with this combo to the point where if you've got a Gen 4 SSD and you put it in the top slot you're going to be getting really good speeds in this case we're measuring over six gigabytes per second transfers so the final thing to talk about is that vrm where with the 7800 X 3D the vrms were going to around mid 80 degrees which is kind of my Max threshold for what I would want to use in my reg personally 24 7 though it did pass the test it did get there though I would recommend if you're getting this motherboard go with a top-down CPU Cooler that puts airflow running through the vrms to give it a little bit of cooling and you should be absolutely fine though the 7800 X 3D itself just like the 7950x3d it runs pretty hot out of the box and like I said in my 7950x 3D review there's just really no way to get this CPU Cooler other than actually manually setting in a temperature limit in the Bios because you don't have really any control of the voltages besides the x670 carrying the PBO curve Optimizer over the a620 which doesn't have that in the Bios you don't have a lot of options there for manually tweaking the x3d chips and this is the same for the 5800x3d where the best I could get on that was around 30 millivolt minus 30 millivolt under volt in this case we don't really get any options to undervolt at all and then on the x670 we only get the option to do very similar to the 5800 x3d so the x3d chips they do run out of the box a bit too hot for my liking especially if you are wanting to keep this for a long time and you'll be playing games for a really long time I would definitely think about going into the bar us and just setting that temperature limit in this case we set it to 75 degrees and that for me we didn't see really any drop in performance on any of these titles in fact the 75 degree limit wasn't actually working probably in the last of us where it was boosting above that but it was working in cinebench R23 so that was pretty good to see but I'd put that limit in there just for Peace of Mind especially if you're going to be using this thing for years and years to come and also in terms of power consumption using an a620 the CPU is using about the same power drawer from the wall and also in the software readout as it is on the x670 so that's some good news they've really this time around with a620 motherboards implemented something that will work absolutely fine with the at least the six and eight cores so in terms of the 7950x or a 7900x I'd personally not go with those CPUs on an a620 and the main reason at least up until this point I'm going to actually ask ASRock about this is is there any way for me to get some manual control of those CPU clocks and voltages even if I'm not overclocking I don't care I want to undervolt those CPUs in particular because if I could undervault I believe something like they're slightly more expensive a620 pro RS for example that would actually be absolutely fine with a tuned 7950x or at least undervolted to around 4.8 gigahertz all cores that would give out some really good I believe Synergy there especially with the 7950x coming down in price though for what it's worth a620 if you guys are looking to save a few bucks and you're getting a six core or an eight core on special this motherboard is certainly going to deliver I was very impressed with the performance very impressed with the use of ease and also as we talked about before if you guys are having idling issues and higher power consumption You may wish to go to the BIOS turn off that one setting and you guys can thank me later in the comments and speaking of comments guys we've got the question of the day which we haven't done in a while and I do apologize for my Hiatus this is actually the question that relates to the highest comes from corn bread man 2012 and they ask hope you're doing all right 12 days since the last video and I do apologize here I have been uh taking a bit of a break after computex that was just a flat out week of just constant work and then from there I got back and I did the D4 PC and to be honest D4 is a game that I have really enjoyed I haven't jumped into a PC game in a long time and just been absolutely immersed and that game did that for me decided to take a bit of a time out and just really enjoy it now I've got my character up to a level where I've pretty much done all I wanted to do with the game and I'm waiting for honestly for blizzard to update the game and so I can try out new things without having to waste time reconfiguring my character already so I'm waiting for them to have different character profiles so in that term I'm done with the game and the good thing is we're now set up with D4 benchmarking to Benchmark it at a real sort of a congested level where we're going to get you guys good numbers at least when it comes to benchmarking that game so sorry for the Hiatus but I guess I needed a bit of a break hope that answers that question and we've got some really cool content coming up in relation to some of the deeper answers that I was digging for at computex so make sure you stay food tuned for that and if you guys enjoyed this video then be sure to hit that sub button ring that Bell and I'll catch you in another tech video very soon peace out for now bye [Music]
