AMD Ryzen 3 3300X improved on-die configuration gives a performance edge

AMD Ryzen 3 3300X steers away from the typical on-die configuration, showing a promising result and makes it looks like potent little chip. On behalf of the internet, I’d like to thank a fella called ‘Vivek’ from OneIndia who got the information from AMD India and leaked it before the non-disclosure agreement’s embargo. AMD typically watermarks its pre-embargo information to journalists and reviewers with a mark across the slides. That’s the only way for any of us to know.

How AMD makes its Ryzen 3000-series CPUs?

This is an oversimplified explanation. Typically, a Zen2 Ryzen 3000 series CPU has two CCDs (Core Chiplet Die) per core. Within each contains 4 CCXs (Core Computing Complex) containing cores, threads and L3 Cache divided evenly. Due to this implementation, AMD Ryzen has 8 Core/ 16 thread at max. Such CPUs will have 2 enabled CCDs, each with 2x 4 CCXs.

The key difference between the Ryzen 3 3100 and the Ryzen 3300X

The Ryzen 3 3100 and the Ryzen 3 3300X are 4 core/ 8 thread with 16MB L3 Cache with 3.6/ 3.9 GHz and 3.9/ 4.3 GHz. Till here, there’s no ‘on paper spec’ difference apart from the clock speed. But the specific difference is the way AMD designed to achieve this.

AMD-Ryzen 3 3300X and Ryzen 3 3100 CCX configuration

Since both of these CPUs are quad-core, each of those contain one CCD. The common relation ends here. Within the CCD in the Ryzen 3 3100, there are two CCX which contain 2 core / 4 threads each. Each CCX contains 8MB L3 Cache. Since each CCX is split into 2+2 configuration, there would be some latency when communicating with eachother. But the Ryzen 3 3300X which has a single CCX enabled, which contains all four cores/ threads with a full 16MB L3 Cache within it. Because of a complete single package, the inter-core latency is reduced. This results in better response and therefore heightened performance. This is also a dramatic shift from what AMD typically does in this Ryzen CPUs.

Because of this, it makes sense why the Ryzen 3300X is very close to the Core i7-7700K in single-thread Cinebench score of 199. With such potent performance throughput from a $120 segment quad-core CPU, it makes a very good chip to pair with an AMD B550 motherboard. It also brings up the conversation if AMD is able to achieve this irrespective of the core configuration they wish to make. We’ll only know in in the future. As of now, these CPUs are destined to be released by next month. The mid-range chipset is expected to be released on the June 16th.
