This is yet another processor from Intel that demonstrates their total market domination in the high end PC sector. The 4820K isn't really a step forward in any particular direction but rather a variant on what's already been available (performance wise) for a few years. As long as Intel is largely competing with itself they will likely continue with these sorts of incremental releases. The 4820K requires an Intel X79 chipset, which dates back to Sandy Bridge-E and lacks some of the newer features like native USB 3.0 support. An investment in the 4820K only makes sense if you already own an LGA2011 Motherboard and could be seen as good money chasing bad given that the platform is due an upgrade. That said the 4820K is a very capable multi-core processor and it sits amongst the top handful of processors in this regard. For typical consumers a Haswell i3 will offer mostly identical response times, a lower energy footprint and a significantly more competitive price. [Nov '13 CPUPro]

The 3700X is a $320 USD 8-core, 16-thread mid-range Ryzen 3000 series CPU. Out of the box, the 3700X, 3600X and 3600 achieve similar quad core speeds but the 16 threaded 3700X is 30% faster at multi-core computations than the 12 threaded 3600X. Comparing the 3700X to Intel’s i7-9700K shows that, when overclocked, the 3700X is 26% faster at 64-core computations but 13% slower for gaming and desktop (sub eight core performance). Unlike lower end Ryzen 3000 SKUs, the 3700X comes with a half decent cooler but AMD should not have bothered since a $20 aftermarket cooler is still quieter, easier to change, and better at cooling. With a Gammaxx 400 cooler we were able to maintain a 43.25x OC during our EFps tests. We had to use a fixed clock OC (rather than Offset/PBO) to avoid significant frame drops in Fortnite. With strong single-core scores, the 3700X should offer very strong gaming performance but in reality it is let down by its memory controller, which, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency. The heavily hyped 3700X, paired with a 2060S, offers real world gaming performance comparable to the $80 USD entry level 4-core, 4-thread Intel Core i3-9100F. At $320 USD, the 3700X offers reasonable value to full time media encoders but general desktop users, gamers and even streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. The 3700X severely bottlenecks a 2070S: gamers should investigate the 9600K, which is both cheaper and faster[Jul '19 CPUPro]

 Frequently Asked Questions

 Best User Rated

Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
