This processor can keep up with even the Intel Core i9-9900K, a processor that considerably costs more and consumes more power, with its TDP of 95W. The AMD Ryzen 7 3700X has a 65W TDP, and with that fairly low amount of power, it's able to deliver quite a lot. Storage: 2TB Gigabyte Aorus M.2 SSD (NVMe PCIe 4.0 x4) Case: Corsair Crystal Series 570X RGB AMD Ryzen 7 3700X: PerformanceĬPU: 3.8Ghz AMD Ryzen 7 3700X (8-core, 36MB cache, up to 4.4GHz) In our own testing, the Aorus PCIe 4.0 SSD that AMD provided was able to get up to 4,996 MB/s sequential read speeds. Through this superior connection, NVMe SSDs are potentially up to 51% faster than their non-PCIe 4.0 peers. However, the way we look at it, SSDs are the real stars of the PCIe 4.0 show. When paired with an AMD Navi graphics card like the AMD Radeon RX 5700 XT or newer, you'll experience much better performance, thanks to increased bandwidth. The major addition to the 3rd Generation of Ryzen, however, is PCIe 4.0. This GameCache isn't anything entirely new, but it does show that this will help boost gaming performance in some cases – especially in older 1080p esports games. This isn't nearly as much as you get with the AMD Ryzen 7 5800X3D, but it's still a lot.Įssentially, this processor has a grand total of 36MB of Cache, which AMD lumps together as 'GameCache'. With the third generation Ryzen chips, as the CPU cores are on their own chiplets, AMD was able to pack way more L2 and 元 cache into the Ryzen 7 3700X – with 4MB and 32MB, respectively. That’s not big enough to be evident in day-to-day workloads, but it does still mean something. Effectively, compared to a second-gen Ryzen processor at the same clock speed, you will get a straight 15% increase in performance. This move to 7nm has brought a beefy 15% boost to IPC (instructions per clock) performance over its predecessor. What this means for most people is lower power consumption and much improved performance at the same time. Basically you are paying a slight premium for the 3800X as it is a better binned 3700X.The AMD Ryzen 7 3700X, like the rest of AMD's Zen 2 processors, is built on a 7nm manufacturing node. Really they are both very good processors and you can't go wrong with either one. I personally won't push past 1.4V, so have never tried either with more voltage than that. The 3700X at max overclock 1.4V can usually come close to 4.4Ghz, however the 3800X can come close to 4.5ghz with the same voltage. Most 3800X can do 4.4Ghz at the same voltage due to better binning. Most of the 3700X I have dealt with can't overclock much past 4.3Ghz all core 1.3 - 1.34V (ie reasonable voltage for a 24/7 overclock). However if you are going to manually overclock your processor then there are gains to be made. If your going to just run stock with XFR doing the boosting for you and possibly use the auto overclock and / or PBO then there really isn't going to be much gained by going to the 3800X. I've dealt with several 3700X and 3800X builds, and honestly if your not going to be manually overclocking there really isn't a huge difference between the two. I know some RAM this isn't the case, I had a kit of Hynix A die that higher frequency and looser timings produced better results than lower frequency and tighter timings. Depending on your RAM you may actually get better performance by lowering frequency to 3600Mhz and running with tighter timings / sub-timings. I am running 3733Mhz CL14 tight sub-timings. I use a voltage offset so I'm not at a sustained high voltage when not under load.Īnother important thing is RAM. I do almost all my overclocking in bios so I just load profile 1 for my everyday overclock (4.4Ghz 1.3V) profile 2 for SMT enabled 4.475Ghz all core (can push 4 cores and 8 threads to 4.5Ghz with ryzen master) 1.406V and profile 3 SMT disabled 4.525Ghz all core 1.406V. At 4.5Ghz+ in single core execution these processors can rival the 9700K, 9900K and even the 9900KS (of course those processors when overclocked past 5Ghz will still hold the edge). It was my first single core optimizations I was trying and am still tinkering with it to see if I can manage a little better single core as programs like Adobe and most games aren't going to make much use out of more than 8 threads and do better with higher frequency. The biggest difference in scores is I am running 4.475Ghz all core for my multi core score and single thread score I disabled SMT and was running 4.525Ghz all core. Deciding between the 3700X and 3800X I took the risk that the better binning would make a difference, and with this processor it was worth the gamble. I had to make the move as I needed my computer up and running and had already promised my 2700X to someone else who needed it and just couldn't put it off any longer. I had a hard time getting a Ryzen 3000 processor because I really wanted the 3900X, but couldn't connect with one.
