Text of the video

AMD is finally launching their ryzen 7000 series x3d processors and they are claiming that this ryzen 97950 x3d should be the absolute fastest gaming CPU that money can buy while using less power than its direct competitors which is a pretty big claim to make so we spent the last couple of weeks testing it in 25 different games on three different resolutions and in this video I'm going to talk about how well it performs in games as well as when it comes to productivity and how power efficient it actually is let's begin the new x3d processors are in many ways similar to the existing 7000 X processors with one big difference the x3d comes with a big chunk of AMD 3D vcache
now they did this with the previous generation ryzen 7 5800 xtd and it turned out that extra cash can really help to improve gaming performance specifically so
now they're adding the same thing to the ryzen 9 models as well but the interesting thing here is that while ryzen 7 5800 x3d only had one block of eight cores this ryzen 9 chip comes with two core complexes that have eight cores each and the 3D V cache is only added to one of those so it has an asymmetric design and the idea behind this is that one half of the chip will benefit all those games and apps that prefer a lot of cash while the other half will deal with games and apps that prefer a higher frequency instead so you basically get the best of both worlds other than the extra cash the differences are actually quite small it is still a 16 core 32 thread CPU the theoretical boost clocks are the same and it is also built on the same five nanometer process however the TDP of the x3d chip is actually much lower the XD has a TDP of 120 watts which is much less than the 170 Watts on the 7950x and it is also half of the TDP of the I9 13 900k but I will talk about the actual power consumption a bit later in this video because I want to talk about the performance first I will be comparing this 7950 XD to the ryzen 97950x as well as the I9 3900k from Intel and to keep it fair we made sure that the AMD and Intel test benches are as comparable as possible and everything was tested and retested using the latest drivers and game updates if you want to know more about the systems or other testing conditions I will leave all the details in the description of this video and you can go ahead and check it out so let's start with some pure CPU benchmarks in cinebench R23 the 7950 x3d has slightly improved performance compared to the 7950x in a single threaded test but AMD is still behind Intel here but in the multi-threaded test the new x3d is actually a little bit slower than both which is what AMD said in their own presentation as well but in a real render workload the impact of that difference is actually quite small so in a short one minute render it is only about three seconds slower than the 7950x and 5 Seconds slower than the I9 and in a slightly longer render AMD starts to pull ahead the I9 is out 20 seconds behind both AMD chips with a 7950x holding on to a very small lead so in terms of productivity the x3d doesn't change that much but this CPU was made with gaming in mind so let's see how it does in games in Microsoft flight simulator which is a notoriously CPU heavy game the 7950 x3d starts off really well average frame rates are much better than on the 7950x and it is beating the I9 3900k as well one percent lows which you can see in the brackets aren't that much better but it is still an improvement overall watchdog's Legion seems to really benefit from this 3D cache as well showing more than 30 percent of an improvement over both the older AMD chip and the iron 9 on 1080p but even on high resolutions that are more GPU bound


now that puts AMD ahead by 4.4 percent on average across 25 games I've tested on 1440p AMD again beats Intel in 14 out of 25 games and in 10 of those by 5 or more meanwhile Intel wins in 10 titles but only in three of those by five percent or more on average AMD is ahead by 3.6 percent which is not a huge margin but still not bad for 1440p resolution on 4K though the graph flips slightly in Intel's favor both CPUs have five games where they win by five percent or more but
now Intel does have a slight advantage in the majority of games that 20 Gap in Far Cry 6 does help AMD to keep the average up which leaves a teeny tiny gap of only 0.2 percent between the two CPUs which is practically a draw but this is where it gets really interesting looking at the CPU power consumption when gaming starting with 4K resolution where performance is very similar between the three CPUs the new 7950 x3d is significantly more efficient it was using only 85 watts of power on average compared to the 122 Watts for the 7950x and 132 Watts for the 3900k and this is in a very GPU heavy scenario on 1080p where we are more CPU bottlenecked that Gap becomes really big
now technically the 3900k is outputting a few frames more in this particular title but it is also using 185 watts to do so compared to the 99 Watts on the 7950 x3d and that is a ridiculous power difference for a very similar performance even compared to the 7950x the x3d manages to offer a lot more FPS while using about 35 Watts less and that power consumption carries over into non-gaming tasks as well if we look at that render Benchmark again they look relatively similar however the x3d does this with an average power draw of 144 Watts which is 84 Watts less than the 7950x for similar performance and about half the power draw of the 3900k while being faster less power also means less heat when fully stressed the 7950x was averaging at 91 degrees Celsius the 3900k was at 94 degrees average while the new x3d was

now this might be an issue with certain motherboards for example so we also went ahead and retested it with a gigabyte motherboard instead of the Asus one and this did show some better results for AMD but it was still using a bit over 10 watts more than the Intel chip in idle that being said it is totally possible that AMD can somehow fix this with an update or that another bios update might help with certain motherboards but for now for right
now the idle power use is definitely something to think about especially if you're using your PC a lot during the day for that basic office use but at the end of the day I do think that the 7950x3d comes out pretty strong it is definitely an upgrade over the 7950x and it is faster than the 3900k on average in basically everything except for 4K gaming where they are actually tight I still don't think anyone that already owns a 7950x or 3900k should just run to the store to buy this one but if you were waiting for it to come out before you got an upgrade it is definitely a very strong option but the price also needs to play a part here on paper the MSRP is set to 699 dollars which matches the MSRP of the 7950x and if they cost the same the x3d here is the obvious choice but in actual shops the price of the 7950x is much lower costing about the same as the 3900k so for
now you really need to think about all these differences and decide how much more you're willing to pay for it and how much would it benefit your particular case that being said I do expect that the XD will be more expensive at launch but the price should go down over time we also have to factor in platform costs as well nowadays you can actually buy a decent b650 motherboard for about 200 or so or an x670e for a bit more than that and even though it only supports more expensive ddr5 memory the price of ddr5 continues to drop down as well so for a high-end CPU like this one I don't think the platform costs are that much of an issue like they were half a year ago technically the z790 boards for an Intel system are still a little bit cheaper in most regions but seeing how with an Intel motherboard you can pretty much forget about future CPU upgrades while AMD here has promised to continue to use the same am5 platform to at least 2025 I think I do think that a small price premium for the CPU and the motherboard combination is completely Justified here and you can all also probably save that difference on cooling because the I9 basically needs a big 360 millimeter all-in-one cooler to keep it running while a good mid-range air cooler will be more than enough for this 7950 x3d this video is brought to you by Corsair and their brand new Dominator Platinum RGB memory these super fast ddr5 6000 Hertz memory kits are specifically made for ryzen 7000 series CPUs they feature a stylish aluminum heat spreader with the dhx technology that keeps them nice and cool under load offering a smooth and stable performance with a lot of room for overclocking and they come with 12 customizable kapelix LEDs that you can control with their IQ software and easily sync up with your other coarser components check them out using the links in the description below and this is where I will leave it for today I really hope you enjoyed this review I'm very sorry for making it this long
