AMD RYZEN 7 5800X3D REVIEW

AMD's fastest gaming CPU ever. But does anyone really need the 'fastest gaming CPU' in their gaming PC?

The new AMD Ryzen 7 5800X3D is then, and it's the fastest gaming processor the red platoon has ever made. It also offers a value proposition Intel's elite gaming CPUs can not contend with, indeed if they're actually the briskly chips in the final reckoning. But that does not change the fact that AMD's new chip is a technically emotional beast, using the rearmost packaging processes from TSMC to plug an devilish quantum of cache into its new CPU. 

 

 Because, after all, what do you do when you can not squeeze any advanced frequentness out of your processor armature? You stick a whole lot further cache memory into it and hope for the stylish. That is what AMD has done on the GPU side with its Perpetuity Cache, pairing up to 128 MB with its RDNA 2 plates cards, to great effect, and now it's doing the same to its CPUs. 

What are the Ryzen 7 5800X3D specs? 

 The Ryzen 7 5800X3D is architecturally identical to the standard Ryzen 7 5800X, using the same Zen 3 processor design, and thus the same chiplet setup that has made AMD's recent generations of CPU similar world- beaters. That means you are getting the same eight core, 16- thread layout in a single chiplet (so no implicitinter-chiplet quiescence issues), but a slightly slower timepiece speed because of a inescapably lower voltage. 

 

 The original Ryzen 7 5800X runs at3.8 GHz with a4.7 GHz boost timepiece, while this new chip comes in with a3.4 GHz base and4.5 GHz boost timepiece. At lower voltages (1.35 v as opposed to1.5 v) the timepiece speed as to be lower in order to remain stable under cargo. This is also one of the reasons the red platoon has nixed overclocking on the 5800X3D, however there are reports that base timepiece tweaking can impinge pets. We have not had any success yet, but we'll keep playing. 

 But AMD is laying on that lower operating frequence being a small price to pay in terms of gaming when it comes to hitting up the total L3 cache on offer from 32 MB, all the way up to 96 MB. 

 

 But trebling the quantum of L3 cache available to an being CPU design, still, needs a little more finesse than simply incinerating it into the cipher bones of a Ryzen processor. 

 And this is where AMD's close relationship with contract manufacturer, TSMC, really comes into play. Using a new 3D packaging fashion, the 5800X3D's cipher chiplet, the Core Complex Die (CCD), has a new chapeau. It's a chapeau made of memory that is roughly half the areal size of the chip it's sat on top of, but contains twice the quantum of L3 cache. 

 

 Though it's like a chapeau that is been clicked to your crown at the molecular position, because it uses a so- called mongrel relating approach that mixes bobby-to- bobby cling with through silicon vias (TSVs) to connect the new cache die to the Zen 3 cipher die. This approach creates a whole cargo of interconnects to insure the data can seamlessly flow between those Zen cores and L3 cache, wherever it's positioned. 

 This redundant cache is named 3D V- Cache, and represents the first time we have seen 3D mounding used within a consumer- concentrated desktop CPU. It's an elegant result, made indeed more so by the fact that despite the redundant V- Cache bones (nicknamed the L3D) sitting on top of the CCD silicon, the performing chip is still the same height as former word Zen 3 CPUs. 

 

 AMD says that, in the manufacturing process, the factual Zen 3 CCD has been weakened down so that the end result is a chiplet that includes the piled L3D on top of the traditional core silicon, yet is no high than in a standard Ryzen 5000-series processor. That all means there is no issue about comity with coolers, and means AMD can use the same heat spreaders, and sockets when it comes to putting it all together. 

 But why would throwing a knob further cache onto a processor have any benefit in gaming terms? The simple answer is that it's each about means and getting access to them snappily. Ultramodern games have lots of, and ever larger, pools of means that need to be loaded in an moment to keep your experience smooth. That each has to be loading into, and brought from memory. Cache memory is the closest to the processor and anything sitting in there can be made readily available to the CPU to use. And if it's not in there the processor has to waste time dipping into the main system memory to snare the necessary data. 

 

 So if you have further of the hastily, near memory — the L3 cache — also theoretically you should see an enhancement in gaming performance … where the CPU might be some kind of tailback, anyway. AMD has been outspoken about the fact that the 3D V- Cache in the Ryzen 7 5800X3D has no impact on productivity operations, marking the chip out as a specific gaming processor. 

 Which brings us neatly onto the content of gaming performance. 

 

 How does the Ryzen 7 5800X3D perform? 

We have put AMD's finest CPU up against what the red platoon firstly called its stylish gaming processor, the Ryzen 9 5950X. The rhetoric seems to have changed since launch, and AMD is now suggesting that the Ryzen 9 5900X is that chip, despite original claims that the top 16- core 5950X was bin sorted to offer the loftiest performance in everything, gaming included. 

 

 We have also tested it against Intel's top processors, the Core i9 12900K and the brand new, special edition Core i9 12900KS. These are Intel's top gaming processors and a marker for where AMD and Intel's separate chips stand when it comes to hurling gaming frame rates around your screen. 

We've checked the cipher performance criteria to punctuate the differences there, but the real meat is in the gaming pets. We are testing at 1080p, with an Nvidia RTX 3080 FE card, to insure our tests are not GPU limited. This will show where there are performance earnings for one CPU or another. 

 

 The catch then's that at advanced judgments the differences are seriously lowered as game performance becomes decreasingly reliant on GPU performance and the speed of a CPU makes little difference beyond a certain point. But that is commodity we'll come back to latterly. For now, let's look at the factual performance. 

In general, the Ryzen 7 5800X3D either basically matches or outperforms the Ryzen 9 5950X. That is a great result considering the top Ryzen is still an precious CPU, and further than ever just a productivity chip and little additional. 

 

 There are also a many times where the new Ryzen CPU outperforms the standard Core i9 12900K, which again is a great achievement. Though, for the utmost part, it lags behind the Golden Cove microarchitecture of the Alder Lake part when it comes to gaming. And, with the special edition Core i9 12900KS coming in with a advanced timepiece speed again compared with the former top Intel processor, the flagship Alder Lake CPU is suitable to keep Intel's claims to'the fastest gaming processor' alive and well. 

While PC gamers arguably watch lower about effectiveness than utmost (after all why would you hanker for an RTX 3090 Ti to gain just a many further frames per second in your games?) it's absolutely worth considering the relative power draws of the two CPU designs. AMD's move to the chiplet setup was a masterstroke, and its 7nm Zen 3 armature is an impressively elegant and effective design. That is instanced by the relative peak wattage numbers of the Intel and AMD processors. 

 

 Under full CPU cargo, running the videotape garbling standard of X264, the Core i9 12900KS demands 77 further power than the Ryzen 7 5800X3D. Though that's with all its performance and effective cores running at full pelt. But indeed when you look at the relative power draw while gaming of the two chips, the Ryzen CPU is suitable to offer much lower power draw while gaming. 

 Taking Far Cry 6 as the illustration then, the Intel chip delivers 23 advanced average frame rates, but with 47 advanced power consumption. 

 

 One thing to note about the 5800X3D, still, is that it's a hot chip. Actually the 12900KS will happily hit 101 °C under full core cargo, but at 93 °C the new eight- core Ryzen CPU runs important hotter than the 16- core 5950X. 

What does the Ryzen 7 5800X3D mean for gaming? 

 Environment is king when it comes to figuring out what applicability releasing a new Ryzen 5000-series chip inmid-2022 actually has. It would be easy to dismiss the Zen 3- grounded 5800X3D in the face of new Zen 4 processors arriving before the end of the time, but it's nearly precisely because of that this new chip has a place. 

 

 The AM4 platform, which has supported the Zen CPUs since they first arrived back in 2017, is going to be effectively retired formerly Zen 4 releases with a new LGA socket this time. But, given that five time heritage, there are going to be a lot of being AMD druggies sitting on an AM4 system they might want to upgrade, but do not want to go through the process of replacing the entire setup. 

 The Ryzen 7 5800X3D is a drop-in upgrade for the maturity of being AMD Ryzen chipsets, and that makes it an easy path to bettered performance for a vast range of AMD druggies. The Zen 4 processors arriving this time, on the other hand, bear a whole new motherboard purchase — probably an precious one originally — and also a new set of precious DDR5 memory, too. Depending on power conditions, you may indeed have to suppose about a new PSU. 

 

 Those are the same arguments against switching to Intel's Alder Lake platform. It may have the advanced gaming performance, but as an upgrade — indeed with a lower spec Intel chip — the platform costs are advanced. 

 The 5800X3D can get mighty close to Alder Lake's gaming frame rates, and you do not have to gutter your entire AMD setup to get there. 

 

 That is a huge plus for the AMD chip, but it still faces competition from within. Substantially because AMD's Ryzen 5000-series prices have dropped significantly in recent months. Right now, it's tough to argue that upgrading your AMD carriage to a$ 450 5800X3D makes further sense than spending lower and grabbing the$ 394 12- core, 24- thread Ryzen 9 5900X. 

 That is one of my favourite ever AMD CPUs, and its gaming performance is still damned emotional. It'll also deliver inconceivablemulti-threaded cipher power, and I would go will still look like a great chip in a couple of times, and a many CPU generations down the line. 

 

 Also we also come to the thorny issue of actually how applicable that whole' stylish gaming CPU' moniker actually is in the realworld.However, there is a real good chance you are not looking to play at 1080p, If you are spending the stylish part of$ 500 on a processor for your gaming system. You will probably have a GPU able of rendering happily at 1440p, and at the point games come more reliant on plates processors than CPUs. Up at 4K, beyond the' good enough' point, your core processor has nearly no bearing on the final frame rates your carriage will deliver. 

 If you are running at RTX 3080 or RX 6800 XT at advanced judgments also redundant cache of the 5800X3D is not going to have enough impact to make it more precious than a 5900X. In those terms also, do you really need further than a Ryzen 5 5600X or Core i5 12600K?
