Boxed yesterday we checked out the six Core ryzen 5 7600x and today we are hands on with the 16 core ryzen 9 7950x of course the 7700x and 7900x reviews are still coming over the next few days so make sure you are subscribed for those we do have a boatloads more data for you speaking of which I'll get to The Benchmark results as quickly as possible but before we do let's go over the 7950x specs what we have here is a 16 core 32 thread zen4 processor that clocks between 4.5 and 5.7 gigahertz depending on the load unlike the 7600x this time we're getting two core complex dies or ccds along with a six nanometer i o die
now the additional CCD means the total L3 cache capacity has increased from 32 megabytes to 64 megabytes and there's
now a total of 16 megabytes worth of L2 cache the TDP has also increased from 105 Watts from the single CCD models to a whopping 170 Watts though do note due to the fact that we're using the same i o die that means the same 28 pcie 5.0 lanes are supported now quite surprisingly whereas its predecessor the 5950x featured a launch price or MSRP of 800 us the 7950x has actually been dropped to 700 us so a 13 discount for what should be a much faster processor though I should note that at present the 5950x can be had for as little as 550 so technically the Zen 416 core model is coming in at an almost 30 premium so given that it will want to be rather Snappy there's a lot more to go over but we'll talk about many of the new features and changes as we work through the review so let's go over the test system specs and then get on with it I've been busy over the past few weeks updating all of our CPU data and as a result we have 17 CPUs for comparison along with the 7600x which we just looked at for the info platform I've got a range of Zen 2 and Zen 3 CPUs with popular models such as the Ambia ryzen 5 3600 AMD ryzen 7 3700x and of course the AMD ryzen 5 5600x but there are half a dozen more models also included then I've got the Intel 10th gen core series including the popular Core i5 i-799 models and due to time I have skipped the 11th gen as that was a bit of a flop anyway then for the 12th gen Core Series processes I've tested using ddr4 3200 dual rank cl14 memory and ddr5 6400 single rank cl32 memory and we have from the core I3 12 100 up to the core I9 1200k for comparison the new am5 test system is based on the MSI Meg x670e Ace and amd's insisted all reviewers use the supplied ddr5 6000cl30 memory so that's what we've done finally please note all testing was conducted using the GeForce RTX 3090 TI Windows 11 and resize all bar was enabled for all test configurations okay let's get into it just quickly before we dive into the blue bar graphs here's a look at clock behavior in cinebench R23 after an hour of load testing the 7950x maintained all core clock frequency of 5.1 gigahertz on the primary CCD and at 4.9 gigahertz on the secondary CCD so there's a four percent frequency discrepancy between the two core complex dies these results were achieved using the be quiet pure Loop 2 FX 360 millimeter liquid cooler installed inside the be quiet silent base 802 then for single core workloads the 7950x appeared to maintain a core clock frequency of 5.725 gigahertz so 25 megahertz above the advertised clock frequency that said at the maximum reported frequency was 5.85 gigahertz though this didn't appear to be achieved under load and all of this clock Behavior was witnessed on the MSI mag x670e Ace starting with the cinebench R23 multi-core results we uh probably should have included some threadripper CPUs I mean damn this thing is fast so for reference the 24 core 48 thread threadripper 3960x that scores about 34 000 points making the 7950x faster perhaps just as impressive as the fact that despite packing half the cores of the 3970x it's just shy of 20 slower so 50 fewer cores less than 20 slower pretty amazing stuff then when compared to mainstream desktop CPUs the 7950x is roughly 40 faster than the core I9 1200k and almost 60 faster than its predecessor the 5950x so again that is incredible as you'd expect given the multi-core performance single core is also very strong meaning the 7950x should really have no weakness here we're looking at a four percent uplift from the 1200k and a 30 improvement from the 5950x moving on to the 7-Zip file manager compression results we see that the 7150x is also very strong here beating the 1200k armed with ddr5 by a 22 margin and the 5950x by 27 margin also for those of you interested it was 73 faster than the 7600x and scaling is poor here as compression doesn't utilize amd's smt very well but where smt does scale well is when looking at decompression performance and here the 7950x is a hundred and fifty percent faster than the

7600x which is quite impressive scaling given that there's a 166 percent more cores then when compared to the 5950x we're looking at a 28 uplift and a massive 90 Boost from Intel's core I9 12900k the 7950x is also a beast in blender delivering 30 greater performance than that of the 5950x and a massive 60 more than the 1200k so AMD looks to be back to dominating Intel in productivity workloads though Raptor could change that shortly the corona Benchmark results are also Mighty impressive a 40 Boost from the 5950x along with a 51 improvement over the 1200k the Premiere Pro 2022 Puget systems Benchmark really surprised me though it probably shouldn't have given how much faster these N3 based 5950x is when compared to the 5600x we're looking at a very similar performance Trend here with Zen four making the 7950x 40 faster than the 7600x which also meant it was 25 faster than the 5950x and 42 percent faster than the 1200k moving on to photoshop 2022 and never before have we seen a ryzen CPU that dominates both Premiere and Photoshop this is because Photoshop relies heavily on single core performance and typically in Telus at the upper hand here however with zen4 that all changes and the 7950x narrowly edged out the 1200k by a mere three percent margin making it 24 faster than the 5950x it's the same story when looking at After Effects previously even the 12 600k was able to match the 5950x but with the 7950x offering 33 more performance it again nudged ahead of the 1200k finally the last productivity Benchmark we have to look at is code compilation performance and here the 7950x delivered 25 greater performance that Intel's current Flagship processor the 1200k the margin from the 5950x was also similar so yet another easy win here for amd's new 16 core Flagship processor now onto the gaming Benchmark so first up we have factorio and I'd just like to apologize for a silly mistake overlooked in the 7600x review previously I showed the score for the 5800 X 3D to be 200 updates per second when in fact it's 352. I've
now corrected that data for this content and all content moving forward also just to clarify I'm running the factorio Box Benchmark here again sorry for the mistake now factorio is very cash sensitive and really only looks at single core performance despite packing twice the L3 cache to that of the 7600x it is split into two ccds which evidently doesn't work all that well here as a result the 7950x was just two percent faster than the 7600x making it four percent slower than the 1200k when paired with ddr5 memory the extra cores of the 7950x helped it jump ahead of the 7600x in watchdog's Legion pushing the average frame rate six percent higher to get within three percent of the 1200k armed with ddr5 6400 memory that's a 22 increase from the 5950x so quite an impressive generational leap year when it comes to gaming performance the Rainbow Six extraction performance was again average though perfectly fine given the 7950x was just four percent slower than the fastest CPU tested the 12900k running ddr560 400 memory moving on to Hitman 3 we find the 7950x is no faster than the 7600x so both were roughly on path to 1200k using ddr5 memory so a good result overall even though Hitman 3 doesn't require more than six Zen 4 cores Tiny Tina's Wonderland has been included not because it's a super CPU demanding game but rather because it's a good representation of how CPU demanding many modern games are that is to say when using a relatively modern CPU most games are going to end up being GPU bound even when using an RTX 3090 TI at 1080p as we see in this example this game could be useful for testing low end CPUs but for the 7950x it just shows that we're able to max out the RTX 3090 TI here matching other high-end CPUs the 7950x was again comparable to the 7600x this time in f122 where it was just a mere two percent faster hitting 340 FPS on average that's a six percent uplift from the 5800x3d and an 11 improvement from the 1200k moving on unfortunately Spider-Man remastered also didn't take advantage of all those extra cores which resulted in the 7950x delivering 7600x light performance and that meant it was significantly slower than the 1200k running ddr5 memory trailing by a 13 margin shadow of the Tomb Raider saw a reasonable six percent Improvement to one percent lows for the 7950x over the 7600x and this placed it alongside the 1200k as the fastest CPU tested in this title like the 7600x the 7950x was impressive in Horizon zero Dawn hitting 212 FPS which saw it lead the 500x30 by 7 margin and the 1200k running ddr5 memory by a 13 margin the cyberpunk 2077 results are interesting because despite only beating the 7600x by a mere one percent margin we're looking at the average frame rate the 7950x was able to boost one percent lows by a far more impressive nine percent that said performance overall was still pretty underwhelming here as the 1200k was 17 faster and that is quite a significant win there for the core I9 processor

ACC also saw little improvement with the 7950x over the 7600x meaning it was a good bit slower than the 5800x 3D but five percent faster than the 1200k now the rift breaker data is interesting as the 7950x was actually six percent slower than the 7600x this appears to be an issue with zen4 processors using dual ccds as I've also observed this frame rate decline with the 7900x amd's aware of the issue and are in contact with the developer to see if there's a solution so this small performance issue may be rectified shortly the last game I'm going to look at is Counter-Strike Global Offensive and here the 7950x improves upon the 7600s already impressive result by additional five percent hitting an average frame rate of 511 FPS that makes it 14 faster than the 1200k using ddr5 memory and a massive 30 faster than the 5950x now here's a look at the 12-game average and as expected the 7950x is barely any faster than the 7600x placing it roughly on part of the 1200k running ddr5 6400 memory as we saw in the 7600x review these N4 CPUs appear to handle ddr5 6400 well and enjoy a small performance boost when doing so so there is a good chance both would nudge just ahead of the 1200k using the same spec memory but either way performance overall is going to be much the same the highlights of the 7950x are the fact that it's five percent faster than the 5800x 3D and 16 faster than the 5950x so some very impressive gains there in gaming for AMD now as impressive as the application in Game of performance is the 7950x does come at a cost and that cost is power whereas the 5950x consumed a similar level of power to that of the 5800x which was an incredible feat the same can't be said for the 7950x which pushed total system power consumption up to 355 Watts so it's a massive 60 increase in total system draw when compared to the 5950x and that means it's actually much worse than the 5950x when it comes to Performance per watt which probably isn't surprising given that the 7600x only matched the 5800x still when compared to Intel it's hardly a poor result using slightly less power the 1200k for around 60 more performance in this test so in terms of power efficiency Zen 4 does Wipe the floor with elder Lake now when it comes to cooling the zen4 CPUs intentionally give the impression that they're difficult to Cool by delivering as much performance as possible by taking full advantage of the thermal and power Headroom AMD states that with the new am5 socket and higher TDP Zen 4 processors will run into a thermal wall before they hit a power wall this means under heavy load they'll sit at TJ Maxx which is about 95 degrees Celsius for the ryzen 7000 series and this will be particularly true for the 12 and 16 core models such as the 7950x AMD stressed that this behavior is intended and by Design and say it's important to note that TJ Maxx is the maximum safe operating temperature but not the absolute maximum temperature in the case of Zen 4 the processors are designed to run at TJ Maxx 24 7 without risk of damage or degradation AMD went on to say that 95 degrees is not running hot rather zen4 will intentionally go to this temperature as much as possible under load because the power management system knows that this is the ideal way to squeeze the most performance out of the chip without damaging it the good news being that almost all am4 coolers will be compatible with am5 the only exceptions being those that are secured from the rear side of the motherboard as the back plates are
now non-removable this means that all coolers can
now be installed without requiring rear access to the motherboard as is the case with hedt processors so that is excellent news now for testing we're using the be quiet pure Loop 2 FX 360 millimeter liquid cooler which is 100 compatible with am5 after an hour of looping the cinebench R23 multi-core test with the pure Loop 2 FX installed inside the be quiet silent base 802 we recorded a peak CPU temperature of 99 degrees for the primary CCD and 96 degrees for the secondary CCD so just above the 95 degree TJ Max that AMD says the CPU targets for maximum performance it'll be interesting to revisit these N4 CPUs using a range of calls see how much the cooling performance affects the cpu's performance but that will be an investigation for another time now time for a value analysis and we'll start with the gaming numbers looking at the cost per frame while only taking into account the price of each CPU as you'd expect given that the 7950x only match the gaming performance of the 7600x the cost per frame is terrible and much worse than that of the 1200k really the 7950x just isn't a gaming CPU
now when factoring in the entire platform cost things don't really improve for the 7950x it's much worse value than Intel's Flagship for gaming and really you just go with something like a core i712 700k or of course the 7600x which

is similar in terms of value again this isn't a gaming CPU and the same will be true of the 7900x these are primarily productivity CPUs that also happen to be really good at gaming but also not better than the six and eight core versions so if you're just gaming get one of those lower core count models and save yourself a heap of money now what the ryzen 9 7950x is good at is productivity really really good for professionals the price to Performance isn't something that matters at least within reason a product that saves time saves money as far as desktop CPUs on a mainstream platform go the 7950x is currently unbeatable costing 33.33 per 1000 points in cinebench R23 when factoring in not just the CPU cost but also the memory and motherboard this makes it 17 better value than the 5950x though again I'd say for most the almost 60 boost in performance is a far bigger draw card the 1200k can't live with it either not only is the 7950x 40 faster here but it's also seven percent better in terms of value for video professionals it's a similar story The 7950x will save you a good chunk of time compared to other desktop CPUs and it's also great from a value perspective matching the 5950x while offering around 15 better value than the 1200k the ryzen 9 7950x really is a jack of all trades apart from maybe power consumption and of course the price there's really nothing to complain about it does everything exceptionally well with no real weaknesses even the price while certainly expensive for what you're getting it's actually very reasonable and as I noted at the start of the review it is a hundred dollar drop at the MSRP from the previous generation so pretty hard to complain about that in most productivity workloads it Stomps the core I9 1200k and as we just saw in the price to Performance comparisons it's also better value as a professional grade product the 7950x is Sensational but as a gaming CPU it's really just Overkill and a bit pointless basically exactly the same situation as N3 then for example if you bought the 5900x or 5950x in an effort to Future proof your gaming experience to date at least you've unfortunately just thrown away a heap of money outside of streaming there is zero benefit to the 12 and 16 core models over the eight core and for the most part even the six core models and the same will be true for Zen 4 if not more so of course if you plan on working as well as gaming from the same PC then nothing does this as well as the 7950x it's unclear at this point how well Intel's core I9 13900k will compete with the 7950x but I suspect we'll know by this time next month so it's probably best to wait until then before making your purchase for those of you interested in the 7950x I feel as though the high x670e board prices won't be a deterrent nor will the price of premium ddr5 memory on top of all that you'll want to ensure excellent case Cooling and above all else bring a big cooler to the table to maximize performance on that note all of the performance shown in this video was achieved using the 125 us be quiet pure Loop 2 FX 360 millimeter liquid cooler so really quite an affordable AIO and certainly one of the cheaper components in a 7950x build as for any additional testing like what was shown in the 7600x review I didn't bother showing all of that again with the 7950x because there's really nothing new there the 7950x scales the same with memory it can handle ddr56000 with four dimms populated and resizable bar or Sam scales as expected overclocking is something I'll probably look at soon in a dedicated content piece and as for the big gaming benchmarks the 7600x and 7700x will be the focus for
now for serving on 50xo really has impressed me it's the ultimate no compromise solution and it's hands down the best at what it does at least for
now it's actually quite impressive that for several Generations
now AMD has been able to dominate with their 16 core desktop CPU the 3950x made a mockery of the core I9 1900k productivity benchmarks though it did lag behind for gaming then the 5950x retired Intel's entire hedt lineup and demolished the 1000k in the process even managing to give it a hard time in the gaming benchmarks the 7950x though has by far faced the stiffest competition from Intel in the 1200k and yet it still managed to come out on top comfortably winning the productivity benchmarks while offering comparable gaming performance so in conclusion I highly recommend the ryzen 9 7950x but I also caution you to wait for Intel's 13th generation core series before pulling the trigger on anything though Intel would really want to hit it out of the park with that one for me to recommend you invest in a dead platform and with that I'm done here if you enjoyed the video make sure you give it a like subscribe for more content as I said 7700x that's going to be a really interesting CPU looking at that tomorrow
