The announcement of the Ryzen 3 3100 and Ryzen 3 3300X processors left us with an interesting question on the table: what configuration had AMD used internally to create these two chips? It is an important question, since both are based on the zen architecture 2, a generation that introduced chiplets and moved I / O elements to an external package.
Each chiplet (CCD unit) has eight cores divided into two CCX units (four cores each) and a maximum of 32 MB of L3 cache, which are divided into 8 MB of L3 cache for each two cores. Thanks to a leaked slide we have been able to see the configuration that AMD has used in the Ryzen 3 3100 and Ryzen 3 3300X, and the truth is that we have had a major surprise.
On the left we have the Ryzen 3 3100, which comes has a total of two active cores in each of the two CCX units, and on the right we have the 3300X, which has four active cores in a CCX unit, which means that the another is completely disabled. Well, this means that in the first one each block of two cores can only access 8 MB of L3 cache, while in the second one all four cores can access 16MB of L3 cache that are available.
The difference between the two is not limited, therefore, to the working frequencies that they bring from home, but as we see they have a deeper range, and should allow the Ryzen 3 3300X to offer slightly higher performance. It is not the first time that AMD has played with the configuration of the active cores in the CCX units, remember that the Ryzen 5 3500 comes with 16 MB of L3 cache while the Ryzen 5 3500X maintains 32 MB L3 cache of the chiplet (CCD drive).
The new Ryzen 3 3000 will be available from May
And with a price that, really, is a bit difficult to fit. Right now we have the Ryzen 5 1600 AF available, based on Zen +, by 99.99 euros, a chip that remains the best solution that exists right now to assemble a gaming PC on a tight budget if we want to play with guarantees both in the short and medium term.
The Ryzen 3 3000 series will offer superior single-wire performance thanks to its higher IPC as they are based on Zen 2, but unlike that, which has six cores and twelve strands, they will be equipped with four cores and eight threads. In some current games, the difference between having four cores and eight threads and having six cores is already beginning to be noticed, a reality that will increase when the arrival of new generation consoles occurs.
If AMD launches this new generation with a price of $ 99 and $ 120, the cost in Spain of both processors, after applying taxes and currency exchange, could easily be around 110 and 130 euros, respectively. For that money, I am clear that a Ryzen 5 1600 AF is the best option, especially as a medium and long-term investment.
It is clear that Zen 2 is a more advanced architecture and that the jump it represents in terms of IPC partly justifies that price, but we are at the beginning of an important transition that will make six-core processors the new standard to play with. guarantees so a six-core, twelve-wire chip is not worth giving up to buy another more expensive four-core and eight-core, claiming that it has a slightly higher CPI (around 10% -12%).
