AMD Ryzen 7 3700X & Ryzen 9 3900X Processor Review

Synthetic Benchmarks

It doesn’t take long to look at these charts and realise that the AMD 3rd Gen CPUs are coming out swinging for Intel’s top dog the i9-9900K. In some, it’s a close call, either sitting behind or ahead and in others, they trample all over Intel. The 3DMark score was a big shift for AMD, scoring the 4th and 5th highest scores to date and within spitting distance of Intel’s top scores. It’s also a hell of a lot ahead of the Ryzen 2700X, showing a 13% improvement since the last generation.

In Unigine and PC Mark 10, the two new CPUs picked up a hell of a pace, smashing out our 1st and 2nd highest scores to date. In both tests, the difference between these and the i9-9900K as well as the last gen Ryzen CPUs is significant.

AMD said they got their single core figures in order too, and they sure as hell didn’t lie. The 3900X did 32M WPrime in a blazing fast 2.429 seconds, and the 3700X was speedy to at 3.128. Plus, with 82 seconds the 3700X just beats the i9. However, the Ryzen 9 was beating some Threadripper parts, and closing in on the £1000-2000 Intel XE processors; simple staggering performance here.

In Cinebench, the single core performance finally broke the 200 mark for AMD for the first time. The Ryzen 7 3700X scored 205 and the Ryzen 9 3900X 209, closing in on the 214 from Intel, but not quite beating it. At least, until we turned on all cores. The 3700X beat the i9 by just 27 points, while the 3900X was over 1000 points in the lead; that’s enough to compete with Threadripper, and again closer to the XE processors.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
