Our assessment of AMD’s 12-core Ryzen 9 3900X CPU, in 5 phrases:

Damn, this CPU is quick.

But preserve studying, as a result of the Ryzen 9 3900X is probably going as vital, and sure as game-changing, as AMD’s unique K7 Athlon-series of CPUs that crossed the 1GHz line first, or its Athlon 64 CPU that ushered in 64-bit computing in a desktop PC.

You’d suppose the Ryzen 9 3900X would have a tough time reaching the identical greatness. It’s true that it would not fairly shake all of the gaming-performance bugaboos of previous generations. But we predict when the mud settles, the CPU collection will simply be a first-ballot, CPU corridor of fame entry.


AMD mentioned it has improved its floating level efficiency by 2X on its Ryzen 3000 collection of CPUs.

It is, in spite of everything, the primary client x86 chip to be produced on a 7nm course of node. Intel’s present desktop chips are nonetheless all constructed on a 14nm course of node, and the corporate will simply start to maneuver to 10nm later this 12 months. We suspect the chip big is slightly envious that AMD reached this tiny die shrink first.

With that manufacturing know-how lead, AMD breaks out a redesigned 2nd technology “Zen” core for the Ryzen 3000 that guarantees double the floating level efficiency over the earlier Ryzen 2000 collection, in addition to a 15-percent enhance in “instructions per clock” (suppose total effectivity per clock).

On a fair deeper stage, AMD mentioned it has improved instruction pre-fetching, additional enhanced the instruction cache and doubled the micro-op cache. Besides doubling the floating level efficiency, AMD has now adopted AVX-256 (256-bit Advanced Vector Extensions) (and sure, Intel followers, we all know Core has AVX-512). AVX’s influence is generally seen in video encoding immediately, however it could actually rear its efficiency head elsewhere too.

AMD has primarily doubled the L3 cache on the Ryzen 3000 chips, and the corporate goes for some Apple-esque advertising by calling it Game Cache. The cache, as much as 70MB on the Ryzen 9 3900X, goes a good distance towards decreasing reminiscence latency on the Ryzen 3000s. It additionally tends to spice up gaming efficiency dramatically on the CPU, so AMD feels calling it Game Cache may also help the typical client perceive its advantages. Yes, that bigger L3—err, Game Cache may also assist utility efficiency, however nobody will get enthusiastic about App Cache we guess.
