The Ryzen 7 3800X is one of five Zen 2 processors that were announced at Computex, with a sixth SKU revealed a short while later. They include the following...
As for the Ryzen 7 3800X, it has 8 physical cores and 16 threads clocked at 3.9GHz to 4.5GHz, and 32MB of L3 cache. In terms of pricing, it goes up against Intel's Core i7-9700K. While AMD has Intel's part listed at $385, street pricing is actually a bit higher—it's listed on Amazon for $406.99.
We don't want to draw too many conclusions based on a leaked benchmark result, but the numbers are interesting. According to the single-core score, AMD has not quite matched (or exceeded) Intel in IPC performance, but it is a lot closer than it was previously (note that the Intel chip is running 300MHz slower while still scoring a little higher).
In multi-core performance, the Ryzen 7 3800X takes the lead. IPC aside, the Ryzen 7 3800X looks to offer similar performance to an Intel part that costs around $100 more. That's impressive. And according to the Geekbench listing, the AMD chip was benchmarked in an X470 motherboard, not a newer X570 board. So, there's the potential for even better performance.
There are also some scores floating around the web of AMD's Ryzen 5 3600. Have a look...
The Ryzen 5 3600 is a 6-core/12-thread processor clocked at 3.6GHz to 4.2GHz, with 32MB of L3 cache. Like the Ryzen 7 3800X, it is a third-generation Ryzen processor based on a 7-nanometer manufacturing process.
If comparing to our own collection of scores, the leaked Ryzen 5 3600 numbers roughly compare to a Core i7-8700K, at least in the Cinebench R15 benchmark run (we don't have numbers for Cinebench R20).
Consider all of this a rough preview. We'll know more of how Zen 2 actually compares to Intel's silicon once we've spent some hands-on time with AMD's new stuff. Stay tuned.
