AMD 7nm Ryzen 3 officially out of the mountains for the first time the introduction of multi-threaded, architectural mystery

Recently, AMD’s third-generation desktop ryufamily welcomed a new member, using the 7nm process, Zen2 architecture of the Ryzen 3 3300X, Ryzen 3 3100 shiny debut, and for the first time in the Ryzen 3 family to introduce multithreaded technology, for entry-level users to bring new choices. Now, the two new models of the structure, performance has been officially lifted, but the domestic listing will be a few days, the specific price will also be announced at that time, the current overseas mobile phones are 120 dollars, 99 dollars.

Don’t miss out on detailed reviews here: i5-9400F and i7-7700K are not rivals! Ryzen 3 3100/3300X Premiere Review

Ryzen 3 3300X is a 4 core 8 thread, base frequency 3.8GHz, up to 4.3GHz, and non-lock frequency, integrated 2MB secondary cache, 16MB three-level cache, support for dual-channel DDR4-3200 memory, 24 PCIe 4.0 channels, thermal design power 65W.

The Ryzen 3 3100 is also a 4 core 8 thread, but the frequency is reduced to 3.6-3.9GHz, and the others are identical.

Both package interface continues AM4, compatible with the 300/400/500 series motherboard, comes with a heat sink ghost Stealth, very conscience is the inside is brazing cooling.

So far, AMD 3rd Generation Desktop Ryzen has formed a complete system from high est in its height, covering all price segments, from the top 12 core 24 threads to the most entry-level 2 Core 4 threads.

Of course, although everyone is the same family product, but there are differences, Rylong 5 3400G, Rylong 3 3200G are used in 12nm Zen plus architecture, speed dragon 3000G or 14nm Zen.

It is important to note that the Ryzen 3 3300X and Ryzen 3 3100 are all 4 core 8 threads and 16MB, but the internal architecture is divided very differently.

We know that the AMD Zen architecture has a modular design of CCD and CCX. Each CCX module consists of four physical cores, a 16MB three-stage cache, and then two CCX modules make up a CCD chip, an eight-core processor such as rye 7 3800X/3700X contains a CCD, and a 12/16 processor core such as rye 9 3900X/3950X contains two CCDs.

At the same time, the three generations of Ryzen internal also integrated an IOD chip, specifically responsible for I/O input and output, GF 12nm process manufacturing.

Ryzen 3 3300X is a set of CCXs that are shielded from a CCD, leaving a complete set of CCXs, that is, the four cores of one, 16MB three-level cache, which can be called a combination of “4 plus 0”.

Ryzen 3 3100 is to mask a CCD in each set of CCX half of the core, three-level cache, leaving their own relatively independent two core, 8MB three-level cache, together to form 4 core, 16MB three-level cache specifications, can be called a “2 plus 2” combination.

It is clear that the structural design of the Ryzen 3 3300X is more advantageous, with four cores and 16MB three-level caches in the same CCX module, lower communication latency between cores, and all cores with out-of-point access to the shared 16MB three-level cache.

The different cores of the Ryzen 3 3100 communicate across CCX, and if the demand for the third-level cache exceeds 8MB, the delay naturally increases across the CCX.

Such a different architecture, resulting in differences in performance between the two in latency, caching, etc., which is also determined by AMD’s product differentiation positioning strategy, but for the vast majority of entry-level applications, for the core, cache latency is not particularly sensitive, so in general the performance difference between the two will not be particularly large.

Here we first look at AMD officially given some performance data, mainly compared to the second generation of Ryzen 3 upgrade, for your reference.

Compared to the Ryzen 3 32300X, in addition to process and architectural progress, the specifications add edgy, the base frequency is 100MHz higher, the acceleration frequency is 100MHz lower, the three-stage cache capacity doubles, the memory frequency is also increased by 266MHz, thermal design power consumption remains the same.

Performance, if CineBench is used as the rule, the Ryzen 3 3100 is up 9%, the multithreaded increase is 44%, and in the 7-Zip multithreaded test is as much as 63%.

In content creation applications, the increase was more encouraging, and the decrease was more than 46% up to 85%.

The game has also improved significantly, with “Ghost Bust 5” reaching a staggering 62% at around 20-30% in general.

Ryzen 3 3300X compared to the Ryzen 3 2300X base, acceleration frequency is higher 300MHz, the advantages are more obvious: CineBench single-threaded increase of 15%, multi-threaded increase of 58%, content creation performance increased by 70-100%, game performance generally improved by about 40%.
